β-Lactam Resistance and Enterobacteriaceae, United States
Extended-spectrum cephalosporins (ESC) are an important drug class for treating severe Salmonella infections. We screened the human collection from the National Antimicrobial Resistance Monitoring System 2000 for ESC resistance mechanisms. Of non-Typhi Salmonella tested, 3.2% (44/1,378) contained blaCMY genes. Novel findings included blaCMY-positive Escherichia coli O157:H7 and a blaSHV-positiv...
متن کاملMolecular identification of coagulase-negative staphylococci isolated from bovine mastitis and detection of β-lactam resistance.
INTRODUCTION Bovine mastitis is a frequent cause of economic loss in dairy herds. Coagulase-negative staphylococci (CoNS) are increasing in importance as causeof bovine intramammary infection (IMI) throughout the world in recent years. CoNShave been isolated from milk samples collected from cows with clinical andsubclinical mastitis in several countries. Identification of mastitis pathogensis i...
متن کاملMolecular Investigations of PenA-mediated β-lactam Resistance in Burkholderia pseudomallei
Burkholderia pseudomallei is the etiological agent of melioidosis. Because of the bacterium's intrinsic resistance and propensity to establish latent infections, melioidosis therapy is complicated and prolonged. Newer generation β-lactams, specifically ceftazidime, are used for acute phase therapy, but resistance to this cephalosporin has been observed. The chromosomally encoded penA gene encod...
متن کاملEvolution of fungal β-lactam biosynthesis gene clusters
Filamentous fungi are microorganisms of great biotechnological interest due to their ability to synthesize a variety of bioactive secondary metabolites including β-lactam antibiotics, such as penicillins and cephalosporins. Hydrophobic (with aromatic side chains) penicillins are only produced by fungi, mainly Penicillium chrysogenum and Aspergillus (Emericella) nidulans, whereas hydrophilic cep...
متن کاملTrimethoprim sulfamethoxazole drug resistance with co resistance to extended spectrum β-lactam antibiotics among bacterial isolates from HIV patients
Background Trimethoprim-sulfamethoxazole (TMP-SMX) is a broad spectrum antimicrobial agent and also reduces the mortality among adults and children when used as prophylaxis against opportunistic infections in HIV infected patients. Drug resistant to TMP-SMX along with Extended spectrum b-lactamase (ESBL) production among Enterobacteriaceae is creating major therapeutic problem in clinical setti...
