The present study was conducted to gain insights into the occurrence and characteristics of extended-spectrum beta-lactamase- (ESBL-) producing Escherichia coli (E. coli) from drinking well water in the rural area of Laiwu, China, and to explore the role of the nearby pit latrine as a contamination source. ESBL-producing E. coli from wells were compared with isolates from pit latrines in the vi...

conclusions based on the presence of ta systems in the majority of p. aeruginosa isolates, these could be used as a novel target for antimicrobial therapy. results our results showed that in the 174 p. aeruginosa isolates, relbe and higba were universal, but parde was less prevalent. both of the flanking regions of the parde genes in all positive isolates were amplified. the flanking regions of...

Background: Plasmid-mediated quinolone resistance (PMQR) determinants are commonly characterized in Klebsiella pneumoniae isolates worldwide and complicate the treatment of infections caused by this bacterium. Objectives: This study aimed to investigate prevalence PMQR molecular typing blood K. Milad hospital Tehran, Iran, within 2018 - 2019. Methods: A total 100 were tested for susceptibility ...

Aim The aim of this study was to characterize virulent Escherichia coli isolated from different poultry species and poultry farm workers using enterobacterial repetitive intergenic consensus-polymerase chain reaction (ERIC-PCR) genotyping. Materials and Methods Fecal swabs from different poultry species (n=150) and poultry farm workers (n=15) were analyzed for E. coli and screened for virulen...

Edwardsiella tarda is an enterobacterial fish pathogen that causes mortality in various fish species worldwide. In this study, we analyzed the intraspecific variability in a collection of E. tarda strains isolated from turbot. To do this we employed 4 polymerase chain reaction (PCR)-based methods: (1) random amplified polymorphic DNA (RAPD), (2) enterobacterial repetitive intergenic consensus-P...

conclusions the high prevalence of oxa β-lactamase and high genetic diversity of p. aeruginosa indicated that the resistance of p. aeruginosa might be expanding in our studied hospitals. background pseudomonas aeruginosa is main bacterial pathogen accountable for nosocomial infections. furthermore, it could potentially become resistant to β-lactams, aminoglycosides and fluoroquinolones antibiot...

To report the presence of viable mycobacteria in a patient with keratitis treated for 6 months. Species identification was performed using the PRA method (polymerase chain reaction followed by restriction endonuclease analysis). Clonality was evaluated with RAPD (randomly amplified polymorphic DNA) and ERIC-PCR (enterobacterial repetitive intergenic consensus-polymerase chain reaction) methods....

Shigella spp are Gram-negative, anaerobic facultative, non-motile, and non-sporulated bacilli of the Enterobacteriaceae family responsible for “Shigellosis” or bacillary dysentery, an important cause of worldwide morbidity and mortality. However, despite this, there are very few epidemiological studies about this bacterium in Brazil. We studied the antibiotic resistance profiles and the clonal ...

ABSTRACT Streptomyces soil rot is a destructive disease of sweetpotato (Ipomoea batatas) that causes yield loss resulting from decay of the feeder root system and reduced quality due to the presence of necrotic lesions on the storage roots. It is managed by the use of resistant cultivars, but variability of the pathogen has not been previously assessed. This study compared 36 strains of the pat...
