OBJECTIVES The aims of this study were (i) to detect extended-spectrum β-lactamase (ESBL) genes among 1378 Escherichia coli isolates from defined disease conditions of companion and farm animals and (ii) to determine the localization and organization of ESBL genes. METHODS E. coli isolates from the German resistance monitoring programme GERM-Vet were included in the study. Plasmids were trans...

Fresh cheese is one of the most consumed products dairy industry in México. This study aimed to determine frequency, antimicrobial resistance, and genetic characteristics extended-spectrum beta-lactamase (ESBL)-producing Escherichia coli fresh cheese. From samples, E. was isolated production ESBL, antibiotic resistance patterns, frequency genes, relationship were analyzed. Sixty ESBL-producing ...

Extended spectrum β-lactamases producing Enterobacteriaceae (ESBL-E) have emerged recently as the main cause that facilitates spreading of antibiotic resistance worldwide. Due to its composition and nutritive values, raw cow milk is vulnerable bacterial contamination from different sources, especially ESBL-E. Accordingly, present study aimed detect ESBL-E in healthy cows. 80 samples were collec...

BACKGROUND Studies about transmission rates of extended-spectrum β-lactamase (ESBL)-producing Enterobacteriaceae in hospitals and households are scarce. METHODS Eighty-two index patients with new carriage of ESBL-producing Escherichia coli (ESBL-Ec; n = 72) or ESBL-producing Klebsiella pneumoniae (ESBL-Kp; n = 10) and their hospital (n = 112) and household (n = 96) contacts were studied prosp...

conclusions more than behalf of the wound isolates were esbl positive, and the presence of blaveb-1 was determined in less than half of these isolates. fortunately, resistance to imipenem and meropenem was low. results the majority of the wound isolates were resistant to augmentin (90%, n = 80) and cefpodoxime (87.6%, n = 78). however, the majority was susceptible to imipenem and meropenem. fif...

Among 120 Escherichia coli isolates from Thai patients, 37 and 9 isolates were extended-spectrum beta-lactamase (ESBL) and suspected ESBL producers respectively while 5 E. coli isolates from 120 Thai healthy adults were suspected ESBL producers. Integrase (intl1) gene was detected in 99% of the clinical and 87% of the non-clinical isolates. Among 37 ESBL producers, percent recovery of bla(TEM),...

Increasing frequency of infections caused by antibiotic resistant Escherichia coli strains producing extended-spectrum β-lactamase (ESBL) needs to be addressed by continuous surveillance and accurate detection of specific ESBLs genes for more effective treatment. A total of 71 β-lactam drug resistant isolates (26 phenotypically ESBL-producing and 45 non-ESBLproducing) were observed to carry app...

The prevalence of extended-spectrum beta-lactamase (ESBL)-producing Escherichia coli (E. coli) is increasing rapidly in both hospital environments and animal farms. A lot of animal manure has been directly applied into arable fields in developing countries. But the impact of ESBL-positive bacteria from animal manure on the agricultural fields is sparse, especially in the rural regions of Tai'an...

Klebsiella pneumoniae causing primary liver abscess (PLA) is emerging. This study identified the beta-lactamases genes of K. pneumoniae isolates in Taiwan. The susceptibilities of beta-lactam antibiotics of 30 K. pneumoniae strains associated with primary liver abscess and 30 noninvasive strains were analyzed. The beta-lactamase genes of randomly selected 24 strains from community-acquired infe...

In the last two decades, Klebsiella pneumoniae demonstrated some characteristics of acquisition of plasmids coding extended spectrum β-lactamases (ESBL). The review data showed an increase in worldwide prevalence of ESBL and a temporal shift in the prevalence of ESBL types in K. pneumoniae during this last decade. CTX-M-15 seems to be the predominant ESBL type in K. pneumoniae in some parts of ...
