Abstract The study reports the MDR, ESBL, and NDM producing Escherichia coli (CRE) isolated from the rescued sloth bear (Melursus ursinus), India. The faecal samples of adult rescued sloth bear (n=21) were collected from a rescue center located in India during 2015-2016 and processed for isolation and antibacterial susceptibility pattern of E. coli. 45E. coli isolates were recovered, and on phenotypic screening, 23 were MDR, 17 were ESBL producers, and five were carbapenem-resistant (CR). The MDR isolates carried beta-lactamase, chloramphenicol, aminoglycosides, tetracycline, fluroquinone, and sulphadimidine resistance genes. All the phenotypic ESBL producing isolates had blaCTX-M genes. On genotypic screening, three CRE (60.0 %, 3/5) were positive for blaNDM carbapenemase gene. Efflux pump-mediated carbapenem resistance was noticed in two CRE isolates (40.0 %, 2/5).The CRE also isolates co-harbored AMR genes like blaTEM-1, blaAmpC, qnrA, qnrB, qnrS, tetA, tetB and sulI. Virulence screening of the resistant isolates revealed the presence of Stx1, Stx2, eae, hlyA genes.Plasmid incompatibility (Inc) typesof three NDM positive isolates revealed that two isolates blaNDM-5 gene on Incl1 an one isolate on IncF plasmid. Apart from NDM genes, the plasmids also carried tetracycline, beta-lactamase and quinolone resistance genes. The plasmid multilocus sequence typing (pMLST) of the E. coli Incl1 plasmid showed the Sequence Type (ST) 297.This appears to be the first report of multi-drug resistant, extended spectrum beta-lactamase (ESBL) producing and blaNDM-5geneson Incl1 and IncF plasmids in rescued sloth bear.

Introduction There are few studies describing colonisation with extended spectrum beta-lactamase-producing Enterobacterales (ESBL-PE) and carbapenem-resistant Enterobacterales (CRE) among children in sub-Saharan Africa. Colonisation often precedes infection and multi-drug-resistant Enterobacterales are important causes of invasive infection. Methods In this prospective cross-sectional study, conducted between April and June 2017, 200 children in a tertiary academic hospital were screened by rectal swab for EBSL-PE and CRE. The resistance-conferring genes were identified using polymerase chain reaction technology. Risk factors for colonisation were also evaluated. Results Overall, 48% (96/200) of the children were colonised with at least one ESBL-PE, 8.3% (8/96) of these with 2 ESBL-PE, and one other child was colonised with a CRE (0.5% (1/200)). Common colonising ESBL-PE were Klebsiella pneumoniae (62.5%, 65/104) and Escherichia coli (34.6%, 36/104). The most frequent ESBL-conferring gene was blaCTX-M in 95% (76/80) of the isolates. No resistance- conferring gene was identified in the CRE isolate (Enterobacter cloacae). Most of the Klebsiella pneumoniae isolates were susceptible to piperacillin/tazobactam (86.2%) and amikacin (63.9%). Similarly, 94.4% and 97.2% of the Escherichia coli isolates were susceptible to piperacillin/tazobactam and amikacin, respectively. Hospitalisation for more than 7 days before study enrolment was associated with ESBL-PE colonisation. Conclusion Approximately half of the hospitalised children in this study were colonised with ESBL-PE. This highlights the need for improved infection prevention and control practices to limit the dissemination of these microorganisms.

AbstractHorizontal gene transfer is an important mechanism which facilitates bacterial populations in overcoming antimicrobial treatment. In this study, a total of 120 Escherichia coli and 62 Salmonella enterica subsp. enterica isolates were isolated from poultry farms in Alberta. Fourteen serovars were identified among Salmonella isolates. Thirty one percent of E. coli isolates were multiclass drug resistant (resistant to ≥ 3 drug classes), while only about 16% of Salmonella isolates were multiclass drug resistant. Among those, eight E. coli isolates had an AmpC-type phenotype, and one Salmonella isolate had an extended-spectrum beta-lactamase (ESBL)-type β-lactamase phenotype. We identified both AmpC-type (blaCMY-2) and ESBL-type (blaTEM) genes in both E. coli and Salmonella isolates. Plasmids from eight of nine E. coli and Salmonella isolates were transferred to recipient strain E. coli J53 through conjugation. Transferable plasmids in above total eight E. coli and Salmonella isolates were also transferred into a lab-made sodium azide-resistant Salmonella recipient through conjugation. The class 1 integrase gene, int1, was detected on plasmids from two E. coli isolates. Further investigation of class 1 integron cassette regions revealed the presence of an aadA gene encoding streptomycin 3”-adenylyltransferase, an aadA1a/aadA2 gene encoding aminoglycoside 3”-O-adenyltransferase, and a putative adenylyltransferase gene. This study provides some insight into potential horizontal gene transfer events of antimicrobial resistance genes between E. coli and Salmonella in poultry production.

Chorioamnionitis, a common complication of pregnancy is associated with significant maternal, perinatal, and long-term adverse outcomes. This case of placental infection leading to preterm delivery, severe neonatal sepsis, maternal wound infection, postnatal readmission, and prolonged hospital stay was caused by multi-drug resistant Extended Spectrum Beta Lactamase (ESBL)-producing Escherichia Coli
