| penetration of bacteria and spermatozoa into bovine cervical mucus. | it has been reported that bacteria may attach to motile spermatozoa, be carried through the cervix and uterus to the fallopian tubes, and cause acute salpingitis. in an attempt to mimic these conditions in vitro, we incubated escherichia coli, streptococcus faecalis, pseudomonas aeruginosa, and staphylococcus aureus with motile spermatozoa which then were allowed to migrate through a capillary filled with bovine cervical mucus. after satisfactory sperm migration through the mucus, the capillarie ... | 1987 | 3110711 |
| therapeutic effects of imipenem-cilastatin on experimental intrauterine infections in rats. | the therapeutic effects of imipenem-cilastatin (mk-0787-mk-791) on experimental intrauterine infections in progesterone-treated virgin rats and postpartum rats were studied. the relative efficacy of imipenem-cilastatin for the treatment of such intrauterine infections was compared with that of cefazolin and ampicillin for the treatment of infections caused by escherichia coli and streptococcus faecalis, respectively. treatment with imipenem-cilastatin significantly inhibited the proliferation of ... | 1987 | 3111355 |
| failure to demonstrate a consistent in vitro bactericidal effect of trimethoprim-sulfamethoxazole against enterococci. | controversy exists as to the in vitro and in vivo activities of trimethoprim-sulfamethoxazole (tmp-smx) against enterococci. in this study, we investigated the in vitro activity of tmp-smx in the type of mueller-hinton broth previously reported to give the lowest mics and mbcs with enterococci. in all instances, mics were less than or equal to 0.5 microgram/ml. the majority of tests showed mbcs of greater than 32 micrograms/ml, although there was some effect from varying the inoculum and the len ... | 1987 | 3111362 |
| comparative survival of antibiotic-resistant and -sensitive fecal indicator bacteria in estuarine water. | the survival of antibiotic-resistant and -sensitive strains of escherichia coli, enterococcus faecalis, enterococcus faecium, streptococcus equinus, and two environmental isolates, ap17 and aq62, was examined in estuarine water. each strain was rendered resistant to a combination of two antibiotics by serial passage in increasing concentrations of antibiotics. cultures were incubated in filter-sterilized estuarine water for up to 7 days. recovery was assessed by examining colony-forming ability ... | 1987 | 3111372 |
| comparison of single and multiple doses of prophylactic antibiotics in experimental streptococcal endocarditis. | single-doses or short-term administration of beta-lactam antibiotics alone or combined with aminoglucoside antibiotics have failed to consistently prevent experimental streptococcal endocarditis induced by high inocula of bacteria poorly susceptible to killing by these antibiotics. the optimal duration of administration of antibiotics for successful prophylaxis under these circumstances has not been established. we therefore tested, in rats with catheter-induced sterile aortic vegetations, the d ... | 1987 | 3111743 |
| comparison of most probable number and pour plate procedures for isolation and enumeration of sulphite-reducing clostridium spores and group d faecal streptococci from oysters. | a comparative study of methods to enumerate sulphite-reducing clostridium spores and group d faecal streptococci in oysters demonstrated that pour plate solid agar techniques gave higher counts than liquid broth most probable number procedures. reinforced clostridial broth with supplements to detect sulphite reduction was compared with pour plates of egg yolk-free tryptose sulphite cycloserine agar incubated at 37 degrees c for 24 h. azide dextrose broth was compared with pour plates using slane ... | 1987 | 3112087 |
| the effect of ampicillin and tylosin on the faecal enterococci of healthy young chickens. | enterococcal isolates from young chickens were differentiated into one of three species, namely enterococcus faecalis, ent. faecium and ent. gallinarum. the proportion of each species among the enterococcal population changed with time in birds not dosed with antibiotics. this pattern of change was modified in birds dosed with either tylosin or ampicillin even though ampicillin did not select for ampicillin resistance among the enterococcal population. a gradual increase in tylosin resistance wa ... | 1987 | 3112089 |
| in vitro activity of ro 19-5247 (t-2525) and interpretive criteria for disk diffusion susceptibility testing. | the activity of ro 19-5247 (the active metabolite of the oral cephalosporin ro 19-5248 [t-2588]) was compared with that of five orally active agents against a total of 331 bacterial strains. ro 19-5247 was more active in vitro than amoxicillin, amoxicillin-clavulanate, cefaclor, cefuroxime, and cephalexin against members of the family enterobacteriaceae. amoxicillin-clavulanate and amoxicillin overall were more active than the other four agents against staphylococci. ro 19-5247, amoxicillin-clav ... | 1987 | 3112176 |

| characterization and comparison of two penicillinase-producing strains of streptococcus (enterococcus) faecalis. | we identified two beta-lactamase-positive enterococci. one strain was high-level (mic, greater than 2,000 microgram/ml) gentamicin resistant; the other was not (mic, 12.5 microgram/ml). beta-lactamase production was extrachromosomally mediated in both strains, and both strains showed an inoculum effect reversed by beta-lactamase inhibitors. the strain lacking high-level gentamicin resistance showed synergistic killing with a combination of penicillin, clavulanic acid, and gentamicin. | 1988 | 3126703 |
| responses of chickens to streptococcus faecalis: genotype-housing interactions. | hens from lines selected for high and low juvenile body weight were maintained in single-bird wire cages or in litter-floor flocks and inoculated intravenously with streptococcus faecalis. responses to the inoculation, as measured by changes in body weight, plasma xanthophyll levels, heterophil/lymphocyte ratios, and mortality, were more severe in the high-body-weight line than the low-body-weight line. the effect of cage vs. floor housing varied according to genetic line. responses of individua ... | 1987 | 3126728 |
| preliminary experience with ceftazidime monotherapy in perinatal infection. | ceftazidime, a new cephalosporin antibiotic, was used as monotherapy to treat 75 term neonates with suspected perinatal bacterial infection. septicemia was documented in ten patients (13%). ceftazidime was administered as 25 mg/kg doses intravenously every 12 h. peak serum concentrations at 0.5 h after dose ranged from 57 to 115 micrograms/ml and trough serum concentrations prior to next dose from 2 to 15 micrograms/ml. the overall clinical, bacteriological and laboratory response to ceftazidime ... | 1987 | 3127359 |
| contribution of the microflora to proteolysis in the human large intestine. | protease activities in human ileal effluent were approximately 20-fold greater than in normal faeces. comparative studies with faeces from a person who did not have a pancreas suggested that a substantial proportion of the proteolytic activity in normal faeces was of bacterial origin. thimerosal, iodoacetate, edta and cysteine significantly inhibited proteolysis in faeces, but not in small intestinal contents, showing that cysteine and metalloproteases were produced by bacteria in the large gut. ... | 1988 | 3127369 |
| the effect of growth-promoting antibiotics on the faecal enterococci of healthy young chickens. | small groups of chickens were given feed containing either avoparcin, nitrovin, virginiamycin or zinc bacitracin from the day of their purchase as day-olds. differences between the birds receiving growth promoters and the untreated controls were observed during the last third of the 23 d survey period. the enterococcal population of the 'dosed' birds contained a greater proportion of enterococcus faecium than did that of the control birds while the converse was true for ent. gallinarum. this app ... | 1988 | 3127371 |
| effects of bacterial infection on absorbable vascular ligating clips. | electron microscopic observations of two implanted absorbable clips, absolok and lactomer, infected with escherichia coli and streptococcus faecalis, were carried out. an overgrowth of bacteria was observed over the entire surface of the clips. the mating surfaces of the lactomer clips and the locking mechanisms of both types of clip were more heavily infected--that is, provided better support for bacterial growth--than other areas of the clips in the initial postimplantation period. however, wi ... | 1988 | 3127583 |
| a shift from acute to chronic spontaneous pyelonephritis in male mm mice associated with a change in the causal micro-organisms. | proteus mirabilis was the predominant cause of acute diabetes-associated pyelonephritis occurring spontaneously in male mm mice until they were segregated in a new environment. thereafter pasteurella pneumotropica and streptococcus faecalis emerged collectively as the most common causal organisms, the pyelonephritis became more chronic and proteus mirabilis isolates from faeces and urine produced atypical non-swarming colonies on blood agar plates. this did not account for the reduced pathogenic ... | 1988 | 3127633 |
| constitutive expression of erythromycin resistance mediated by the ermam determinant of plasmid pam beta 1 results from deletion of 5' leader peptide sequences. | we have sequenced the erythromycin resistance determinant (erm) of the streptococcus faecalis plasmid pam beta 1 to investigate its relationship to other known resistance determinants. we show that this determinant is strongly (99%) homologous at the dna level to that of plasmid pam77 (streptococcus sanguis) and of transposon tn917 (s. faecalis). moreover, nucleotide sequence comparison with the determinants of pam77 and tn917 shows that most of the probable regulatory region is absent, providin ... | 1987 | 3127839 |
| enterococcal superinfection in patients treated with ciprofloxacin. | two patients developed serious enterococcal superinfection following therapy with intravenous ciprofloxacin. the strains causing bacteraemia were susceptible to low concentrations of ciprofloxacin when tested at a standard inoculum. however, at an inoculum of 1 x 10(7) cfu/ml they were resistant to high concentrations of ciprofloxacin. our data suggest that ciprofloxacin should not be used to treat patients with serious enterococcal infection and that patients treated with ciprofloxacin should b ... | 1988 | 3128516 |
| comparison of 1% silver sulfadiazine with and without 1% chlorhexidine digluconate for topical antibacterial effect in the burnt infected rat. | the addition of 1% chlorhexidine digluconate to 1% silver sulfadiazine cream (cdss) was compared with 1% silver sulfadiazine (ss) alone to assess the antibacterial effect of a once-daily application of the therapies on an experimental rat model with a 20% full-thickness burn wound seeded with 10(8) microorganisms originally isolated from infected wounds of burn patients. separate series evaluated staphylococcus aureus, pseudomonas aeruginosa, enterobacter cloacae, and streptococcus faecalis. the ... | 1988 | 3128553 |
| evaluation of the cobas bact automated system for susceptibility testing of enterobacteriaceae, pseudomonas aeruginosa, and enterococcus faecalis to azlocillin, mezlocillin, and ciprofloxacin compared to nccls and din standards. | the aim of automated susceptibility testing systems like the cobas bact is to provide the clinicians with rapid and reliable results for the care of patients and to decrease the work load in microbiological laboratories. because data about accuracy on mezlocillin, azlocillin and ciprofloxacin were lacking, we investigated 184 bacterial strains and compared the results of the cobas bact susceptibility testing to standardized agar dilution and agar diffusion methods. essential correlations for all ... | 1988 | 3129374 |
| an open study of the safety and efficacy of enoxacin in complicated urinary tract infections. | thirty-one patients with serious or complicated urinary tract infections were treated with oral enoxacin for between four and eight days. twenty-five patients with microbiologically confirmed infections completed treatment with 400 mg enoxacin twice daily and at the end of treatment all urine cultures were negative. at short term follow-up, five to nine days after therapy, 21 of the 25 patients were still infection free. in total, reinfection or relapse occurred in 12 patients during the four to ... | 1988 | 3129393 |
