| upper respiratory tract infections. ecological and therapeutic aspects of beta-lactamase production with special reference to branhamella catarrhalis. | available data indicate that the most common beta-lactamase produced by branhamella catarrhalis is plasmid mediated. the same enzyme occurs in moraxella nonliquefaciens, a commensal in the upper respiratory tract. the ability to produce the enzyme, which is known as bro-1, can be transferred by conjugation from m. nonliquefaciens to b. catarrhalis. since the first beta-lactamase-producing strains of b. catarrhalis appeared in 1977, the frequency of beta-lactamase production has increased rapidly ... | 1986 | 3488190 |
| plasmid-mediated beta-lactamase in branhamella catarrhalis. | the plasmid-mediated beta-lactamase in branhamella catarrhalis (bro-1), also occurring in moraxella nonliquefaciens, differs from other known plasmid-mediated beta-lactamases in gram-negative bacteria regarding substrate profile and isoelectric point. b. catarrhalis strains previously reported to produce beta-lactamases deviating from bro-1 were tested, and the beta-lactamases did not differ significantly from bro-1 in substrate profile, isoelectric point or relative substrate affinity index (rs ... | 1986 | 3488198 |
| beta-lactamase production in the upper respiratory tract flora. | in order to determine the recovery rate of species of the genera haemophilus and moraxella (including subgenus branhamella) from the upper respiratory tract and the incidence of beta-lactamase production within these genera, cultures were made of nose and throat swab specimens and adenoid tissue in 50 children undergoing adenoidectomy. haemophilus influenzae was isolated from 92% of the children. all children harboured strains of haemophilus spp. and in 46%, at least one strain produced the tem- ... | 1986 | 3490974 |
| disk diffusion susceptibility of branhamella catarrhalis and relationship of beta-lactam zone size to beta-lactamase production. | we tested 231 isolates of branhamella catarrhalis for beta-lactamase production and drug susceptibility by the national committee for clinical laboratory standards disk diffusion method. the nitrocephin disk (cefinase) identified beta-lactamase in 98% of the enzyme-producing strains, and a zone diameter of inhibition of less than or equal to 29 mm for penicillin correctly predicted the presence of beta-lactamase in 99% of the isolates. no resistance to erythromycin, tetracycline, trimethoprim-su ... | 1986 | 3492178 |
| activation of b chronic lymphocytic leukaemia cells by branhamella catarrhalis. | cells from the blood of patients with chronic lymphocytic leukaemia were cultured in the presence of two polyclonal activators of human b cells, the bacteria branhamella catarrhalis (bc) and staphylococcus aureus cowan 1 (sac). although the magnitude of the responses varied, cells from seven of the eight patients studied were induced to proliferate in response to bc. in contrast, the response to sac was low or negligible in seven of the eight patients, and only one patient responded well to this ... | 1987 | 3493206 |
| in vitro activity of bmy 28100, a new oral cephalosporin. | bmy 28100, a new oral cephalosporin, demonstrated good in vitro activity against common gram-positive and gram-negative respiratory and urinary tract pathogens. its activity was shown by microdilution techniques to be generally higher than those of ampicillin, cephalothin and cephalexin, but comparable to those of cefaclor and, except for haemophilus spp. and branhamella spp., to amoxicillin/clavulanate. | 1987 | 3494601 |
| amoxycillin/clavulanate in acute purulent exacerbations of chronic bronchitis. | twenty patients, all admitted to hospital with acute purulent exacerbations of chronic bronchitis associated with haemophilus influenzae, streptococcus pneumoniae or beta-lactamase producing branhamella catarrhalis were treated twice daily for ten days with amoxycillin/clavulanate. ten patients were first given 1000 mg amoxycillin with 200 mg potassium clavulanate intravenously bd for three days, before crossing to the standard oral regimen of 1000 mg amoxycillin + 250 mg potassium clavulanate b ... | 1987 | 3494724 |
| comparative antibacterial activity of the new oral cephalosporin bmy-28100. | the in vitro activity of bmy-28100 was compared with that of four other oral cephalosporins against gram-positive cocci, branhamella catarrhalis and haemophilus influenzae. bmy-28100 showed 5-20 times better activity against staphylococci and streptococci. methicillin-resistant staphylococci and enterococci were resistant to the drug. branhamella catarrhalis and haemophilus influenzae strains were moderately susceptible. time-kill curve studies showed bmy-28100 to be equally as active as benzylp ... | 1987 | 3497804 |
| detection of beta-lactamase activity among clinical isolates of branhamella catarrhalis with six different beta-lactamase assays. | a total of 74 different clinical isolates of branhamella catarrhalis were examined for their ability to produce beta-lactamase by six different beta-lactamase assays. these included a conventional tube and disk test, in which the chromogenic cephalosporin nitrocefin was used as a substrate; a disk procedure, in which pyridinium-2-azo-p-dimethylanaline cephalosporin was used as a substrate; broth and disk acidometric methods; and a conventional tube iodometric assay. a total of 58 of the study is ... | 1987 | 3497942 |
| infectious bovine keratoconjunctivitis: evidence for genetic modulation of resistance in purebred hereford cattle. | a vaccination study was conducted in a herd of purebred hereford cattle representing 4 selection (genetic) lines. for each of 2 years, half of the cattle were vaccinated with a pilus-enriched moraxella bovis bacterin. cows were vaccinated before parturition, and calves were vaccinated at 2 to 3 months of age. none of the cattle was vaccinated for 1 year preceding and 1 year after the 2 years in which cattle were vaccinated. there was a significantly (p less than 0.05) lower percentage of infecti ... | 1986 | 3516033 |
| critical evaluation of the automicrobic system gram-negative identification card for identification of glucose-nonfermenting gram-negative rods. | during a 6-month study we critically evaluated the accuracy of the automicrobic system gram-negative identification card (vitek systems, inc., hazelwood, mo.) in identifying glucose-nonfermenting gram-negative bacilli by testing 419 selected isolates in parallel with a conventional reference method. of 356 isolates included in the automicrobic system profile, a total of 307 (86.2%) were correctly identified, 36 (10.1%) were not identified, and 13 (3.7%) were misidentified. fifty-eight of 63 (92% ... | 1986 | 3517050 |
