“…One of the major findings of the study is to bacterial resistance against colistin (43.24%), which is striking and worrying. Colistin, the last resort drug, is being used extensively in agriculture and veterinary medicine [21], but its use in human medicine is restricted because of nephrotoxicity and neurotoxicity. The present study revealed that ceftriaxone, gentamicin, and erythromycin were sensitive to 56.76%, 56.76%, and 43.24% isolates, respectively, while Azad et al [20] reported 36% to gentamicin and 100% to erythromycin.…”

Objective:The present study was carried out to appraise the antibiotic resistance and to detect some of the target resistant genes in Escherichia coli (E. coli) isolated from apparently healthy broilers.Materials and Methods:Cloacal swab samples (n = 60) were collected from apparently healthy broilers (n = 60) sold at two different live bird markets (LBMs) of Chattogram, Bangladesh. Isolation and identification of the Escherichia coli was done by the following standard bacteriological techniques followed by biochemical tests. The antibiotic susceptibility of E. coli isolates was determined by the disk diffusion method. The antibiotic resistant genes were detected by polymerase chain reaction (PCR) using specific primers.Results:The overall prevalence of E. coli in broilers was 61.67% (n = 37/60) (95% CI = 49–72.93). The antibiogram study showed that the isolates were 100% resistant to ampicillin and tetracycline followed by sulfomethoxazole-trimethoprim (94.59%, n = 35/37) and nalidixic acid (91.89%, n = 34/37). To the contrary, 56.76% (n = 21/37) isolates were sensitive to both ceftriaxone and gentamicin followed by colistin (48.65%, n = 18/37). All of E. coli isolates were multidrug resistant (MDR) and carried blaTEM, tetA, and Sul2 genes.Conclusion:The presence of MDR genes in E. coli isolates in broilers could pose a serious public health threat.

“…However, all the isolates showed 100% sensitivity to colistin sulfate followed by ceftriaxone (78%) and ciprofloxacin (39%), according to Xue et al [17], who reported 52% susceptibility against ciprofloxacin. Although colistin sulfate was susceptible to all isolates in our study, the last resort drug is being used extensively in agriculture and veterinary medicine [18].…”

Objectives:The present study was carried out to assess the antibiotic resistance and to identify the resistance genes in Escherichia coli from captive Bengal tigers at two Safari parks in Bangladesh.Materials and Methods:A number of 24 environmental fecal swab samples of Bengal tigers were collected from two different Safari parks in Bangladesh. For the isolation of E. coli, samples were submitted to a number of bacteriological screening and biochemical tests. The antibiotic susceptibility of E. coli isolates was determined by disk diffusion method.Results:Results demonstrated that 18 environmental fecal samples were positive to E. coli in bacteriological screening and biochemical test. The overall prevalence of E. coli in Bengal tiger was 75% (n = 18/24). The antibiogram study unveiled that all the isolates were resistant to ampicillin. Sulfamethoxazole-trimethoprim, nalidixic acid, and tetracycline were 89% (n = 16/18) resistant. On the contrary, 100% (n = 18/18) of the isolates were sensitive to colistin sulfate. blaTEM was detected in 78% (n = 14/18) ampicillin-resistant isolates, whereas sul2 was found in 31% (n = 5/16) of the sulfamethoxazole-trimethoprim-resistant isolates.Conclusion:This study, first time in Bangladesh, highlights a significant proportion of environmental fecal samples from captive Bengal tigers at Safari parks harboring antibiotic resistant E. coli. Transmission of resistant E. coli from Bengal tigers to humans and the environment could pose a public health risk at Safari parks in Bangladesh.

“…These antimicrobials are recommended to be antimicrobials of last resort for treating bacterial infections. Also, [36] reported that all their E. coli isolates were resistant against colistin. According to [37], for many decades, colistin was not recommended for use due to its toxicity and the availability of other safer antimicrobials such as penicillins.…”

Background Rising incidences of antimicrobial resistance has become a major public health issue globally resulting in increasing health-care costs and severe and lethal diseases. Several reports have documented alarming increases of antimicrobial resistance in the Enterobacteriaceae family, hence, this study evaluated the occurrence and antibiogram signatures of Enterobacteriaceae isolates recovered from vegetables, hospital effluents and river water samples in two district municipalities in the Eastern Cape Province, South Africa. Results Out of 142 presumptive isolates, 105 were confirmed to belong to the Enterobacteriaceae family. From these, 45% were identified as E. coli, 24% as Enterobacter spp., 20% as Citrobacter spp. and 11% as Klebsiella spp. All the isolates demonstrated high resistance against ampicillin at a frequency of 91.4%, followed by nalidixic acid (86.7%), tetracycline (82.9%), cefuroxime (81.9%) and doxycycline (81.9%). The beta-lactam resistance gene blaTEM was detected in 77.8% of the E. coli isolates and 33.3% of the Klebsiella isolates. The sul1 gene was detected in 23.1% of the Enterobacter species, while sul2 gene was detected in 70% of the Klebsiella species. All the Enterobacter species were positive for the strB gene. Conclusions We conclude that the vegetables, hospital effluents and river water in the two District Municipalities are reservoirs of multidrug resistant members of the Enterobacteriaceae family and a potential health hazard for consumers.
