Correlation of the effect of beta-lactamase inhibitors on the beta-lactamase in growing cultures of gram-negative bacteria with their effect on the isolated beta-lactamase [PDF]
Antimicrobial Agents and Chemotherapy, 1984 The effectiveness of clavulanic acid, sulbactam, quinacillin sulfone, and the carbapenems MM13902 and MM4550 as inhibitors of TEM-2 beta-lactamase in growing cultures of gram-negative bacteria has been studied. Each of these beta-lactams inhibited the enzyme in intact cells, and the nature of the inhibition correlated with studies on the purified ...

Veterinary Medicine and Science, Volume 9, Issue 1, Page 226-233, January 2023., 2023 Abstract Background Evaluating the prevalence of vancomycin resistance genes (van genes) in enterococcal isolates from food‐producing animals is an important public health issue because of the possibility of resistance genes spread to human. Objectives The present study aimed to determine the occurrence of vancomycin resistance genes among Enterococcus

Plasmid-determined beta-lactamase indistinguishable from the chromosomal beta-lactamase of Escherichia coli [PDF]
Journal of Bacteriology, 1976 A plasmid, derived from a naturally occurring strain of Proteus mirabilis, conferred resistance to cephalosporins, apparently mediated by a beta-lactamase indistinguishable from that determined by the chromosomal gene of Escherichia coli K-12. There was evidence for a recombination event between the wild-type plasmid and a defective F factor (Fsp) in ...

Beta-lactamase production among multidrug-resistant wound isolates from patients attending University College Hospital, Ibadan, Oyo State, Nigeria [PDF]
Microbes and Infectious DiseasesBackground: Wound infections have been a problem in the field of medicine for a long time due to the emergence and re-emergence of drug resistance. The assessment of Beta-lactamase production, plasmid profiling and corresponding resistance pattern in the

Veterinary Medicine and Science, Volume 9, Issue 1, Page 513-522, January 2023., 2023 The average isolation rate of livestock‐associated S. aureus is 6.5%, and the S. aureus isolates showed high resistance to a wide range of antimicrobials. Most strains, with the exception of three chicken‐associated strains, harbored blaTEM‐1a gene. All S.

The .BETA.-lactamases of genus Bacteroides.
The Journal of Antibiotics, 1983 Two hundred anaerobic isolates from clinical specimens were examined for beta-lactamase production by Nitrocefin methodology. Altogether, 77 strains were beta-lactamase producers. Organisms belonging to Bacteroides melaninogenicus group, i.e., B. intermedius and B.

Oral flora of domestic cats in Hong Kong: Identification of antibiotic‐resistant strains
Veterinary Medicine and Science, Volume 9, Issue 1, Page 25-36, January 2023., 2023 Abstract Background As the clinical outcome of bite‐associated infection is related to the oral commensals, evaluating their composition and antibiotic susceptibility pattern can provide more information for the antibiotic treatment of wound infections and increase the awareness of the multidrug‐resistant bacteria in cat oral flora. Aims This study was
