Extended Spectrum β-Lactamase-Producing Escherichia coli and Klebsiella pneumoniae from Broiler Liver in the Center of Algeria, with Detection of CTX-M-55 and B2/ST131-CTX-M-15 in Escherichia coli

Antimicrobial Resistance Genes and Diversity of Clones among ESBL- and Acquired AmpC-Producing Escherichia coli Isolated from Fecal Samples of Healthy and Sick Cats in Portugal

“…To our knowledge, there is only one previous report related to the detection of this clone in humans, performed in healthy children in Sweden [53]. Furthermore, this clone was also detected in E. coli isolates from broilers in Algeria, associated with the B1 phylogroup [54].…”

Prevalence and antimicrobial susceptibility profiles of ESBL-producing Klebsiella Pneumoniae from broiler chicken farms in Shandong Province, China

“…A study in the Netherlands showed that antibiotic-resistance genes may be transmitted from poultry through the food chain to humans who are in close contact with them, as similar ESBL-producing isolates have been found in poultry meat and humans that are in close contact ( Leverstein-van Hall et al, 2011 ). In this study, the overall prevalence of ESBL genes in K. pneumoniae isolates was 100% (n = 33), a proportion that is higher than: that of a Shandong broiler slaughterhouse, where 96.67% (87/90) were ESBL-producing strains ( Wu et al, 2016 ); the ESBL production rate of a healthy meat and poultry farm in India (1/20, 5%) ( Bhardwaj et al, 2021 ); that of broiler liver from Algeria, where the proportion of ESBL isolates was 3.70% ( Chenouf et al, 2021 ); and Germany's separation rate of chicken meat, which was 17.50% (35/200) ( Eibach et al, 2018 ). The most common ESBL genes were bla SHV (n = 31/33, 93.94%), bla OXA64gp (n = 30/33, 90.91%), and bla TEM (n = 21/33, 63.64%).…”

First Report of Extended-Spectrum β-Lactamase ( bla CTX-M1 ) and Colistin Resistance Gene mcr-1 in E. coli of Lineage ST648 from Cockroaches in Tunisia

“…bla CTX-M-15 was the most dominant ESBL type ( n = 8). It was found in four isolates from cockroaches collected from collective catering, typed as ST8149 or ST2010 (each n = 2, in E. coli and K. pneumoniae , respectively), those STs having been described in several studies in animal, food, and environmental isolates ( 40 , 41 ). Three CTX-M15-producing isolates recovered from the hospital were typed as ST2914 ( n = 2; E. coli ), which has been reported in only one study in isolates of migratory birds in Pakistan ( 42 ), or ST551 ( n = 1; K. pneumoniae ), previously detected in human and environmental isolates ( 43 , 44 ).…”
