Escherichia coli isolates from various sources 2018 to 2019 were included in the study. Mcr-1 genes found two of 105 animal strains (2%) and seven 928 human (0.8%). All mcr-1-positive showed a low level resistance colistin (MIC ranged 4 8 µg/ml). Both isolated animals remained sensitive betalactam antibiotics did not contain beta-lactamase genes. Beta-lactamases absent only one humans. Four res...
INTRODUCTION The aim of this study was to determine the prevalence of extended-spectrum beta-lactamase (ESBL) producing Escherichia coli (E. coli), Klebsiella pneumoniae (K. pneumoniae), and Proteus mirabilis (P. mirabilis). In addition, different methods for detection of these enzymes, including the newly introduced CHROMagar ESBL, were evaluated. METHODOLOGY A total of 382 Enterobacteriacea...
Shigellosis is a major source of gastroenteritis throughout the world (14). Extended-spectrum -lactamases (ESBLs), including cefotaximases (CTX-M), confer resistance to extendedspectrum cephalosporins and significantly compromise the treatment options for shigellosis. Numerous ESBLs have been described among Enterobacteriaceae (2, 8, 13); however, only a single CTX-M-producing Shigella isolate ...
Extended-Spectrum Beta-Lactamase (ESBL)-producing bacteria are a common cause of healthcare and community-associated infections worldwide. The distribution of such isolates in the environment and their presence in fish as a result of sewage contamination is not well-studied. Here we examined fish and environmental samples from Mwanza city for the presence of ESBL-producing bacteria. From 196 fi...
Nosocomial infections are very common in African hospitals, particularly in neonatal units. These infections are most often caused by bacteria such as Escherichia coli, Klebsiella spp and Staphylococcus spp. Salmonella strains are rarely involved in nosocomial infections. Here, we report the first description of S. Grumpensis in neonatal infections in Senegal. Seventeen Salmonella strains were ...
Background and purpose: Citrobacter species can cause opportunistic hospital-acquired infections and their treatment has become problematic following the acquisition of extended spectrum beta- lactamases (ESBLs). The purpose of this study was to determine the frequency of ESBL genes in clinical isolates in Kermanshah Imam Reza Hospital. Materials and methods: In this study, 70 Citrobacter isol...
Background: The increasing pattern of Multi-Drug Resistant (MDR) bacteria has limited therapeutic options especially for nosocomial isolates of Klebsiella pneumoniae. Therefore, the aim of this study was the molecular detection of 16S rRNA methylase and blaCTX-M-15 among K. pneumoniae strains isolated from hospitalized patients in Mofid, Imam Hossein and Taleghani hospitals. Materials and Me...
We screened 30 Klebsiella pneumoniae isolates from dogs and cats at a single animal hospital in Guangdong Province, China. Among them, 12 K. pneumoniae strains possessed high-level resistance to amikacin and gentamicin and these were screened for 16S rRNA methyltransferase (16S-RMTase) genes. And then the genes positive isolates were detected for ESBLs (extended spectrum β-lactamases) and analy...
Background Due to increasing colistin usage, the dissemination of the colistin-resistant gene mcr-1 has been increasingly investigated. The aim of this study was to determine whether a traveler on a short-term international trip to a developing country could bring mcr-1 back to their home country. Materials and methods Thirty-four travel events from Japan to Vietnam encompassing 19 travelers ...
