Comparative analysis of phylogenetic group and antimicrobial resistance pattern of fecal Escherichia coli isolates between healthy dogs and their owners
Abstract To compare the phylogenetic group and antimicrobial resistance pattern of fecal Escherichia coli from dogs and their owners in Shiraz, Iran, a total of 385 E. coli was isolated from 32 dog–owner pairs and 17 control humans. All isolates were subjected to Clermont PCR phylotyping and standard disk diffusion susceptibility testing to 13 antibiotics. Phylogenetic group distribution was significantly different among dogs, owners, and controls. Highest resistance was found to ampicillin (100 %) followed by amoxicillin (96.6 %) and trimethoprim–sulfamethoxazole (57.1 %) and lowest to meropenem (2.3 %) and imipenem (5.5 %). Phylogroup D was accounted for higher antimicrobial resistance. Multidrug resistance (MDR) was found in 76.9 % of isolates. Prevalence of antimicrobial resistance and MDR of E. coli isolates from owners were almost similar to dogs and were more prevalent in compared to controls. Similar resistance profile was found in 9.3 % of dog–owner pairs. No hand washing after petting and before owner’s meal or feeding dogs, allowing the dogs to enter inside home, sleeping in the same bed, licking on owner face, and feeding dogs with people foods are common behaviors which can be risk factors for increasing the chance of transmission of resistant bacteria between dogs and their owners directly in either directions or through the environment.
ConclusionThe spread of NDM variants among E. coli strains is a serious threat to global public health. In addition, the most prevalent E. coli clonal groups, such as ST101 and ST167, are one of the main causes of E. coli infection in different countries.
ConclusionsThis study reported ESBL-producing Enterobacteriaceae in Tunisian camels from both tourist and meat-producing sectors. This was the first description of the mcr-1 gene in a meat-producing camel. Although not alarming, this context needs specific attention to avoid camels becoming a bigger reservoir for multidrug-resistant Enterobacteriaceae.
ConclusionsTo our knowledge, this is the first draft genome of an E. coli ST131-O25:H4-H30 strain recovered from infant diarrheal stool sample in Mexico. The genome sequence of E. coli M51-3 presented here will be helpful to understand the genomic diversity of this highly virulent and MDR successfully pandemic bacterial pathogen.
Abstract Background/Aims: Among patients with febrile neutropenia that developed after chemotherapy, high-risk patients, such as those having clinical instability or Multinational Association of Supportive Care in Cancer score of
ConclusionsThe co-existence of the mcr-1 and ESBL/AmpC genes and the very high level of multiple drug resistance in all colistin-resistant E. coli isolates obtained from sampled chicken farms in Vietnam is a major concern.
Authors: Bader MS, Loeb M, Leto D, Brooks AA Abstract Urinary tract infections (UTIs) caused by antibiotic- resistant Gram-negative bacteria are a growing concern due to limited treatment options. Knowledge of the common uropathogens in addition to local susceptibility patterns is essential in determining appropriate empiric antibiotic therapy of UTIs. The recommended first-line empiric antibiotic therapy for acute uncomplicated bacterial cystitis in otherwise healthy adult nonpregnant females is a 5-day course of nitrofurantion, a 3-g single dose of fosfomycin tromethamine, or a 5-day course of pevmecillinam. High...
ConclusionIt is concluded that NIT resistance in the studied NIT-RE. coli isolates was mainly mediated by nfsA and nfsB alterations.

ménez F, Marin C Abstract Wild birds have repeatedly been found to be involved in the dissemination of enteric bacterial pathogens in the environment. The aim of this study was to determine the occurrence of Salmonella and Campylobacter as well as the antimicrobial resistance in wild Bonelli's eagles nestlings in Eastern Spain. In addition, we compared the efficiency of two sampling methods (fresh faecal samples from nest and cloacal swabs from nestlings) for detection of both bacteria. A total of 28 nests with 45 nestlings were analysed. In the nest, Salmonella occurrence was 61 ± 9.2%...
ConclusionGiven the widespread use of penicillins and tetracyclines in animal health, co-resistance to amoxicillin and tetracycline could be an efficient indicator of MDR in E. coli isolates. Based on a specific resistance profile and not an arbitrary number of resistances compared with MDR, this potential indicator is also precise, convenient and suitable for routine use.
