| lipid composition of the electron transport membrane of haemophilus parainfluenzae. | the principal lipids associated with the electron transport membrane of haemophilus parainfluenzae are phosphatidylethanolamine (78%), phosphatidylmonomethylethanolamine (0.4%), phosphatidylglycerol (18%), phosphatidylcholine (0.4%), phosphatidylserine (0.4%), phosphatidic acid (0.2%), and cardiolipin (3.0%). phospholipids account for 98.4% of the extractible fatty acids. there are no glycolipids, plasmalogens, alkyl ethers, or lipo amino acid esters in the membrane lipids. glycerol phosphate es ... | 1968 | 5685994 |
| phospholipid metabolism during changes in the proportions of membrane-bound respiratory pigments in haemophilus parainfluenzae. | after a transition from high to low oxygen tension, there was a twofold to 50-fold increase in the content of membrane-bound respiratory pigments of haemophilus parainfluenzae, and there were concurrent changes in the metabolism of the membrane phospholipids: (i) a twofold decrease in the rate of turnover of the phosphate in all the phospholipids; (ii) a shift from simple one-phase, linear incorporation of phosphate into phospholipids to a complex biphasic incorporation of phosphate into phospho ... | 1969 | 5764329 |
| indentification and localization of the fatty acids in haemophilus parainfluenzae. | haemophilus parainfluenzae was capable of synthesizing 22 fatty acids. these fatty acids were equivalent to 4% of the bacterial dry weight. these fatty acids were localized in the membrane-wall complex, which contained the respiratory pigments, the quinone, and the phospholipids. the fatty acids which could be extracted with organic solvents comprised 86% of the total fatty acids of the cell. these fatty acids were distributed as 98% in the phospholipids and 1.9% in the neutral lipids, of which ... | 1967 | 6025415 |
| transposon tn10-like tetracycline resistance determinants in haemophilus parainfluenzae. | tetracycline resistance (tcr) determinants from three different strains of haemophilus parainfluenzae expressed 10-fold higher levels of resistance when mated into escherichia coli. no plasmid was found in any of the e. coli recipients, even in matings in which a plasmid was identified in the donor haemophilus sp. the tcr determinant from haemophilus sp. caused instability of resident plasmids in the recipient e. coli: all plasmids were lost within 30 generations in antibiotic-free media. howeve ... | 1984 | 6090437 |
| treatment of 160 cases of acute bacterial meningitis with cefotaxime. | one hundred and sixty cases of acute bacterial meningitis were treated with cefotaxime. patients were between 9 days and 79 years old: 7 new borns, 37 infants, 43 children, 19 adolescents and 54 adults. fifty-eight patients (36%) were in coma when admitted. aetiology was determined in 110 patients (68.8%): neisseria meningitidis in 42, streptococcus pneumoniae in 36, haemophilus influenzae in 16, salmonella spp. in 7, staphylococcus aureus in 2, enterobacter spp. in 2 and haemophilus parainfluen ... | 1984 | 6094440 |
| occurrence of pili on and adhesive properties of haemophilus parainfluenzae. | of 20 clinical isolates of haemophilus parainfluenzae, 13 produced a mannose-resistant hemagglutinin that agglutinated erythrocytes from chickens, horses, rabbits, and sheep. examination with the electron microscope showed that only strain hr-885 was pilate. grown in static liquid culture, the 12 hemagglutinating, nonpilate isolates formed small, tightly packed clumps, whereas strain hr-885 formed large, loosely packed clumps. however, seven isolates did not produce a hemagglutinin, did not clum ... | 1981 | 6109710 |
| fimbriation of haemophilus species isolated from the respiratory tract of adults. | twenty-two clinical isolates of haemophilus species were studied within two passages of their original isolation for the presence of fimbriae by negative-staining electron microscopy. six isolates were identified as fimbriated, including three strains of nontypable haemophilus influenzae, one strain of haemophilus parainfluenzae, and two strains of haemophilus haemolyticus. in fresh isolates of fimbriated strains of nontypable h. influenzae, approximately 40%-50% of cells had fimbriae; after fiv ... | 1984 | 6146651 |
| urinary tract infection caused by haemophilus parainfluenzae. | a case of haemophilus parainfluenzae urinary tract infection is reported, with clinical history and bacteriologic data. other reports of this organism causing urinary tract infection could not be found. the importance of correlating data from clean-catch urine microscopic analysis, gram stain, and culture is emphasized, together with the possible modes of spread in a compromised host. | 1980 | 6153501 |
| isolation and characterization of two proteins possessing hpa ii methylase activity. | two proteins exhibiting hpa ii methylase activity have been purified to homogeneity from haemophilus parainfluenzae and their physical and catalytic properties have been studied. separation of the two hpa ii methylase activities was achieved by deae-sephadex a-50 chromatography. in subsequent steps, each methylase was purified separately by chromatography on sephacryl s-200, phosphocellulose, and hydroxylapatite. the proteins have molecular weights of 38,500 +/- 1,000 (hpa ii) and 41,500 +/- 1,0 ... | 1980 | 6248522 |
| uptake of plasmid deoxyribonucleic acid by haemophilus. | the uptake of circular and linear plasmid rsf0885 deoxyribonucleic acids, (dnas) obtained from haemophilus parainfluenzae 14, in both homologous and heterologous recipients was studied and compared with that of chromosomal dna. high concentrations of divalent cations stimulated the uptake of either circular or linear plasmid dna in h. parainfluenzae 14 competent cells but did not affect the uptake of chromosomal dna. the biological activity of linear plasmid dna was similar to that of circular d ... | 1981 | 6260748 |
| the somatic replication of dna methylation. | we have tested the hypothesis that dna methylation patterns are replicated in the somatic cells of vertebrates. using m-hpa ii, the modification enzyme from haemophilus parainfluenzae which methylates the internal cytosine residues in the sequence 5'ccgg 3' ggcc, we methylated bacteriophage phi x174 rf dna and the cloned chicken thymidine kinase (tk) gene in vitro and then introduced these dnas and unmethylated controls into tk- cultured mouse cells by dna-mediated transformation. twenty-five ce ... | 1981 | 6263490 |
| molecular nature of a plasmid specifying beta-lactamase production in haemophilus ducreyi. | we characterized pjb1, the plasmid previously reported to mediate beta-lactamase production in haemophilus ducreyi. we studied its relationship to pmr0360 and rsf0885, the plasmids responsible for beta-lactamase production in neisseria gonorrhoeae and haemophilus parainfluenzae, respectively. although pjb1 was maintained as a multicopy pool in escherichia coli, it was not stably maintained in the absence of antibiotic selection. electron microscope heteroduplex studies showed that it carried 100 ... | 1981 | 6273382 |
| in vitro activity of cefotaxime, ceftizoxime, cefmenoxime, and latamoxef in comparison with other beta-lactam antibiotics against recent clinical isolates of haemophilus influenzae and haemophilus parainfluenzae. | 1982 | 6290854 | |
| interaction of bacteriophage t7 with hind-endonuclease-producing haemophilus influenzae rd cells. | in order to test the influence of the restriction endonucleases of haemophilus species on in vivo dna restriction of phage t7 and its close relative t3 as well as to determine whether the anti-dna restriction effect of the t7 and t3 ocr+ gene is also expressed in haemophilus cells, we studied the interaction of t7 and t3 with haemophilus influenzae serotypes rd and rc and haemophilus parainfluenzae. the results show that t7 and t3 are unable to infect these bacterial species because they do not ... | 1982 | 6291263 |
| antibiotic treatment of haemophilus influenzae and haemophilus parainfluenzae infections in patients with cystic fibrosis. | during the period 1977-81, 188 cystic fibrosis patients have been treated with 1 254 anti-haemophilus treatments in the danish cystic fibrosis center. on an average, each patient received 1.7 courses of chemotherapy per year. haemophilus infections were more prevalent in the youngest age group of patients. the average number of h. influenzae precipitins increased with age, and this pattern was consistent throughout the whole study. the standard treatment was orally administered pivampicillin or ... | 1984 | 6331710 |
| relative proportions of haemophilus species in the throat of healthy children and adults. | to determine normal proportions of pharyngeal haemophilus species, qualitative and quantitative mapping of the species in the pharynx of ten healthy children and ten healthy adults was carried out using a selective and a non-selective medium. haemophilus organisms were present in all samples, comprising approximately 10% of the total cultivable flora (range 0.6-36.9%). haemophilus parainfluenzae was a member of the normal flora throughout life, constituting 74% of pharyngeal haemophilus organism ... | 1984 | 6332018 |
| the acid end-products of glucose metabolism of oral and other haemophili. | the acids produced in broth culture by various species of oral haemophili and by stock strains of capsulated and other haemophili were identified and measured by gas-liquid chromatography. succinic acid was the major acid end-product of all strains, with acetic acid also being regularly produced but in smaller amounts. a stock strain, haemophilus parainfluenzae nctc 4101, produced less succinic acid than other strains of haemophili. strain nctc 4101 possessed all the enzymes of the tricarboxylic ... | 1984 | 6332175 |
| bacteremia caused by a beta-lactamase producing haemophilus parainfluenzae strain of a new biotype. a case report. | a case of haemophilus parainfluenzae bacteremia without known infectious focus is reported. phenotypically, the isolated strain is a typical h. parainfluenzae except for its ability to produce indole and beta-lactamase. beta-lactamase producing h. parainfluenzae organisms are encountered occasionally, but to the best of our knowledge this is the first reported blood culture isolate with this ability. we propose a new biotype (iv) of h. parainfluenzae to accommodate strains that are indole, ureas ... | 1984 | 6333136 |

| biotyping of haemophilus using api 10s--an epidemiological tool? | one hundred and ninety-nine strains of haemophilus isolates were biotyped by kilian's method(1) and a modified api 10s strip and the results compared. one hundred percent correlation was found between the two systems. the onpg test proved of value in differentiating between haemophilus influenzae and haemophilus parainfluenzae when there was growth factor disc failure. | 1983 | 6337192 |
| potential significance of colonization with beta-lactamase-producing haemophilus parainfluenzae in children. | recent surveys in vancouver showed most healthy children were colonized with beta-lactamase-producing haemophilus parainfluenzae. such organisms might alter the effects of penicillins on throat bacteria by local inactivation. to test this hypothesis in vitro, three isolates of beta-lactamase-producing haemophilus parainfluenzae were each mixed on a membrane with ampicillin-sensitive strains of haemophilus influenzae type b or group a streptococcus pyogenes and exposed to ampicillin. when tested ... | 1983 | 6349987 |
| development of a test system for rapid differentiation of neisseria and haemophilus spp. | a qualitative micromethod (ids rapid nh system) employing conventional and single-substrate enzyme tests was developed for the biochemical characterization of neisseria spp., haemophilus spp., and other gram-negative species. a total of over 140 dehydrated, miniaturized biochemical tests were investigated for their ability to distinguish species. computer-assisted test selection and pair separation analysis of the data allowed the selection of 11 4-h tests that would identify haemophilus and nei ... | 1983 | 6358247 |

| antimicrobial resistance in haemophilus isolates: a minnesota experience and literature review. | annual ampicillin susceptibility rates for haemophilus influenzae isolates at the st. paul-ramsey medical center gradually decreased from 100% in 1974 to 83.3% in 1980 and then remained stable at 88.90%. penicillin susceptibility rates were similar to those for ampicillin. ampicillin rates were source dependent: eye 95%, respiratory 90%, miscellaneous sources 82%, and blood and csf 80%. rates for haemophilus parainfluenzae varied and showed no trend. h. parainfluenzae isolates were distinctly le ... | 1984 | 6380270 |
| haemophilus parainfluenzae lung abscess. | to our knowledge, haemophilus parainfluenzae lung abscess has not been described previously. such a case is presented in the setting of diabetes mellitus. the implications of diagnosis and management are discussed. | 1984 | 6395241 |
| antimicrobial susceptibility testing of haemophilus parainfluenzae by a kinetic killing-curve method. | a kinetic killing-curve method, designed to mimic several aspects of clinical therapy in endocarditis, was used to test 10 strains of haemophilus parainfluenzae against 28 antibiotic regimens. in an effort to simulate changing in vivo levels of antibiotic in serum, concentrations of three penicillins, three cephalosporins, gentamicin, and chloramphenicol were sequentially adjusted over a 12-hr period. against six beta-lactamase-negative strains, gentamicin in combination with penicillin or cepha ... | 1980 | 6444977 |
| [fundamental and clinical studies of cefoperazone in children (author's transl)]. | as a result of conducting experimental and clinical tests with the newly developed cephalosporin, cefoperazone (cpz), the following conclusions were obtained: (1) when tested against 10 strains of staphylococcus aureus and 16 strains of staphylococcus epidermidis, the antibacterial activity of cpz was found to be weaker than that of cez. against 5 strains of a-beta-streptococcus and 4 strains of streptococcus pneumoniae, both cpz and cez exhibited similar excellent antibacterial activity. cpz wa ... | 1980 | 6451730 |
| [clinical evaluation of 6059-s therapy in children (author's transl)]. | a new semisynthetic 1-oxa-beta-lactam derivative, 6059-s, was evaluated for its safety and efficacy in children. twenty-five patients were treated with 10 to 274 mg/kg per day of 6059-s by intravenous administrations. the diagnosis of the patients were acute pharyngitis (2), acute bronchitis (2), pneumonia (4), pertussis (4), acute enterocolitis (2), recurrent urinary tract infection (2), suspected septicemia (3), and acute purulent meningitis (1); and the remaining 5 patients were considered to ... | 1981 | 6457168 |
| haemophilus parainfluenzae endocarditis on tricuspid valve. | after an episode of intermittent fever which lasted 45 days, endocarditis of the tricuspid valve was diagnosed using m-mode echocardiography in a 17-year-old female patient who had no history of drug abuse. after unsuccessful therapy with ampicillin, tetracycline and aminoglycosides, clinical improvement was achieved by treatment with temocillin. | 1984 | 6478467 |
| distribution of oral haemophilus species in dental plaque from a large adult population. | the periodontal status of maxillary first molars in 284 young adults demonstrating near-health to early disease was evaluated, and supragingival and subgingival plaque samples were collected. plaque samples were processed anaerobically, enumerated microscopically for bacterial morphotypes, and cultivated on various media to enumerate the microflora. although haemophili were ubiquitous (recovered in 98.5 and 96.2% of the supragingival and subgingival plaque samples, respectively), 50% of the resp ... | 1984 | 6500711 |
| erythromycin-sulfisoxazole for persistent acute otitis media due to ampicillin-resistant haemophilus influenzae. | in patients with acute otitis media who had failed to improve with ampicillin therapy, 35% of haemophilus strains isolated from the middle ear were ampicillin-resistant. twenty-nine children (24 of whom had failed to respond to ampicillin) were treated with 40 mg erythromycin ethylsuccinate per kg per day and 100 to 150 mg sulfisoxazole per kg per day. middle ear exudate was cultured on chocolate and 5% sheep blood agar. twenty-three of 29 haemophilus isolates were nontypable, 10% (3 children) w ... | 1983 | 6601265 |

| rapid species identification and biotyping of respiratory isolates of haemophilus spp. | three commercially available systems, the 4-h minitek enterobacteriaceae iii, the haemophilus trio-tube, and the micro-id, were evaluated for their capacities to identify and biotype 308 respiratory isolates of haemophilus spp. when compared with aminolevulinic acid test results, the definitive identification method used in this study, these systems demonstrated no significant differences in their capacities to differentiate haemophilus influenzae from haemophilus parainfluenzae. they were in ag ... | 1983 | 6630435 |
| liver abscess caused by haemophilus parainfluenzae. | a case of liver abscess caused by haemophilus parainfluenzae in an otherwise healthy adult is described which responded to medical management without surgery. this we believe to be the first reported case of liver abscess caused by this organism in the english medical literature. | 1983 | 6657541 |
| isolation of haemophilus species from the genital tract. | haemophilus influenzae was isolated from the urethra of three of 85 men attending a sexually transmitted diseases clinic. these isolates of h. influenzae were nonencapsulated; one was biotype iii, and two were biotype iv. haemophilus parainfluenzae was isolated from the urethra or coronal sulcus of five men; three isolates were biotype ii, and two were biotype iii. neither h. influenzae nor h. parainfluenzae was isolated from the genital secretions of 84 women. haemophilus ducreyi and haemophilu ... | 1983 | 6658630 |
| trimethoprim-sulfamethoxazole in the treatment of otitis media secondary to ampicillin-resistant strains of haemophilus influenzae. | between august 1977 and january 1979, 16 children (7 males and 9 females) ranging in age from 5 to 38 months (mean age 18 months) were treated with trimethoprim-sulfamethoxazole (tmp-smx) (40 mg/kg smx per 24 hours) for otitis media caused by beta-lactamase strains of ampicillin-resistant haemophilus influenzae. fourteen patients had failed after antecedent ten-day courses of ampicillin (9 patients) or amoxicillin (5 patients) therapy. the remaining two patients received only five days of ampici ... | 1980 | 6778328 |
| penicillinase-producing neisseria gonorrhoeae in the netherlands: epidemiology and genetic and molecular characterization of their plasmids. | penicillinase-producing neisseria gonorrhoeae strains were isolated in the netherlands with increasing frequency during the period of 1976 to 1979. about 3% of the gonococci isolated in the first half of 1979 produced penicillinase. in contrast to the period of 1976 to 1977, most penicillinase-producing n. gonorrhoeae infections during the period of 1978 to 1979 were contracted in the netherlands. the results of genetic and molecular studies on 80 penicillinase-producing n. gonorrhoeae strains w ... | 1980 | 6778387 |
| frequency of ampicillin-resistant haemophilus parainfluenzae in children. | ampicillin resistance has been described in haemophilus species other than haemophilus influenzae, but its frequency and significance are uncertain. in a throat-culture survey, beta-lactamase-producing haemophilus parainfluenzae was detected in 192 (72%) of 266 ambulatory children. ampicillin-resistant h. parainfluenzae was more frequently found in children from three to four years of age (88%) or in those who attended day-care programs (97%) and less frequently in older children and parents (33 ... | 1981 | 6785367 |
| urethritis associated with haemophilus parainfluenzae: a case report. | haemophilus parainfluenzae was isolated from the urethral discharge of a man with urethritis. the patient responded favorably to treatment with amoxicillin. although the facts suggest that this case of urethritis may have been caused by h. parainfluenzae, a possible etiologic role of other microorganisms is not ruled out. | 1983 | 6845118 |
| management of complications of infective endocarditis. | complications of infective endocarditis may be considered as those that involve the heart and adjacent structures or those that are extracardiac. congestive heart failure is the most common serious complication of infective endocarditis and is the leading cause of death among patients with this infection. in patients with severe heart failure unresponsive to medical therapy after 24 to 48 hours, prompt cardiac valve replacement should be considered, irrespective of the duration of preoperative a ... | 1982 | 6895923 |
| possible mechanism for donor dna binding and transport in haemophilus. | morphological differences were observed in competent and noncompetent haemophilus parainfluenzae and haemophilus influenzae when thin sections of these cells were examined by electron microscopy. the membranous extensions present on the surface of competent h. parainfluenzae cells disappeared on treatment with transforming dna, while vacuole-like structures appeared in the periplasm. noncompetent cells had 1/5th as many extensions on their surface as competent cells, and no vacuoles were observe ... | 1982 | 6959125 |
| chromosomally integrated conjugative plasmids are common in antibiotic-resistant haemophilus influenzae. | twenty-three highly antibiotic-resistant strains of haemophilus influenzae and two of haemophilus parainfluenzae without detectable large plasmids were examined for conjugative transfer of their resistance to h. influenzae strain rd or to other strains. very inefficient transfer was observed for 18 h. influenzae strains and 1 h. parainfluenzae strain. all h. influenzae transcipients carried a large plasmid, and they were in turn efficient donors of their resistances in standard conjugation cross ... | 1980 | 6966629 |

| haemophilus parainfluenzae endocarditis: application of a molecular approach for identification of pathogenic bacterial species. | haemophilus parainfluenzae is both a human oropharyngeal commensal bacterium and a cause of serious invasive disease. the fastidious growth characteristics of this organism and the poor specificity of traditional methods for species identification are likely to have led to inaccuracies in the diagnosis of infections caused by h. parainfluenzae and related organisms. we report a case of h. parainfluenzae endocarditis in which confusion related to microbial identification was resolved by the analy ... | 1994 | 7528552 |
| [detection of beta-lactamase in samples obtained after tonsillectomy in children]. | production of beta-lactamase was detected using a microbiological assay (guts test) in samples of tonsils, and by in haemophilus growing from the same samples of both tonsils obtained from 30 children aged 2 to 13 years (18 aged < 6 years and 12 aged > or = 6 years). two pieces from each tonsil, core and superficial, were studied. the procedure included direct microscopic examination of smears, and culture to identify haemophilus, beta-haemolytic streptococci and streptococcus pneumoniae. guts t ... | 1995 | 7567124 |
| phylogeny of the pasteurellaceae as determined by comparison of 16s ribosomal ribonucleic acid sequences. | previously, virtually complete 16s ribosomal ribonucleic acid sequences were determined for 54 strains of species in the family pasteurellaceae. the sequences for 16 additional strains have been determined, bringing the total number of strains sequenced to 70. the additional strains include: actinobacillus hominis, a. muris, a. salpingitis, pasteurella bettyae, p. mairii, p. testudinis, and bisgaard taxa 2, 3, 5, 6, 7, 8, 9, 13, and 14 (2 strains). a phylogenetic tree was constructed based upon ... | 1993 | 7690271 |
| [clinical and laboratory studies on sy5555 in pediatric infectious diseases]. | clinical effects of sy5555 dry syrup, a new oral penem antibiotic, were analysed in 20 children with various bacterial infections. ages of the patients varied from 8 months to 14 years. doses of sy5555 were varied from 12.8 mg/kg/day to 30.5 mg/kg/day, and it was administered in 3 divided dosages. clinical efficacy rates were as follows; 6/7 in acute bronchitis, 5/5 in pharyngotonsillitis, 3/3 in acute otitis media and 2/2 in cystitis and 3/3 in impetigo contagiosa. the overall rate was 95.0% (1 ... | 1995 | 7745813 |
| hpaii methyltransferase is mutagenic in escherichia coli. | a genetic reversion assay to study c-to-t mutations within cg sites in dna is described. it was used to demonstrate that the presence of hpaii methyltransferase (mtase) in escherichia coli causes a substantial increase in c-to-t mutations at cg sites. this is similar to the known mutagenic effects of e. coli mtase dcm within its own recognition sequence. with this genetic system, a homolog of an e. coli dna repair gene in haemophilus parainfluenzae was tested for antimutagenic activity. unexpect ... | 1995 | 7751315 |
| affinity, conservation, and surface exposure of hemopexin-binding proteins in haemophilus influenzae. | haemophilus influenzae can acquire heme from hemopexin for use as a source of both essential porphyrin and iron. in classical ligand-binding studies, we observed time-dependent, saturable, and displaceable binding of human 125i-labelled hemopexin to intact cells of h. influenzae type b (hib) strain 760705 grown in an iron-restricted medium. from these experiments, which demonstrate that hemopexin associates with a single class of binding site, the affinities (kds) and receptor numbers were calcu ... | 1995 | 7768617 |
