Escherichia coli is a common cause of infections in companion animals. In recent years the increasing prevalence of resistance to β-lactams, including extended-spectrum cephalosporins, antimicrobials frequently used in small animal veterinary practice, was observed in canine isolates of E. coli. The aim of this study was to detect and to characterize extended-spectrum β-lactamases (ESBLs) produ...

The emergence of resistance to extended-spectrum cephalosporins in salmonellae is an increasing clinical problem. We report the characteristics of a ceftriaxone-resistant Salmonella enterica serovar Hadar strain collected in 2001 from a patient with a postoperative wound infection in a university hospital in Taiwan. Resistance to extended-spectrum cephalosporins was found to be due to productio...

Resistance to broad spectrum β lactams, mediated by extended spectrum beta lactamase (ESβL) and AmpC βL enzymes is fast spreading in Nigerian hospitals. Production of these enzymes has resulted in treatment failure especially if one of the second or third generation cephalosporins is used. A study was undertaken to determine the prevalence of each enzyme and coproduction of the two enzymes amon...

Background: Escherichia coli is one of the most common causative agent of urinary tract infection. In recent years, resistance to cephalosporins has been considerably on the rise due to production of extended spectrum beta-lactamases (ESBLs.( This study was aimed to determine the survey of CTX-M, SHV, TEM, OXA-1, PER-2, and VEB-1 which are the most famous ESBL genes in E. coli isolated from out...

OBJECTIVES To investigate the prevalence of extended-spectrum cephalosporinase (ESC)-producing Escherichia coli in pigs at slaughter and retail meat, and possible associations with the consumption of third- and fourth-generation cephalosporins. METHODS During 2009, faecal samples from Danish pigs (n=786) were collected at slaughter, and 866 meat samples [Danish: pork (153), broiler meat (121)...
