Background: There are scarce reports about the association of Klebsiella oxytoca ( K. ) with urinary tract infection (UTI) in children. We aimed to evaluate prevalence fimA, mrkA, matB and pilQ adhesins genes extended-spectrum beta-lactamase (ESBL) blaCTX-M, blaTEM blaSHV by polymerase chain reaction (PCR) study biofilm formation antibiotics resistance from children UTI. Methods: This was a ret...

Background: Carbapenem-resistant Acinetobacter baumannii strains are one of the most severe factors in hospital infection worldwide, which beta-lactamase enzyme is main resistance mechanisms. Objectives: This study aimed to evaluate presence carbapenem-resistant genes and determine antibiotic patterns clinical isolates A. from patients hospitalized Shahid Kamyab Hospital, Mashhad, Iran. Methods...

The use of antibiotics in veterinary and human treatment can cause the development antibiotic resistance bacteria for β-lactam antibiotics. Worldwide, this has become a growing concern public health. Limited data are currently available regarding Extended Spectrum β-Lactamase (ESBL) Escherichia coli Indonesia. current study determined prevalence characteristics ESBL genes E. retail chicken meat...

Collared peccaries (Pecari tajacu) roam the forests of natural areas in America. Wild collared peccary appears to be a carrier for bacteria associated with infections humans and animals, however, presence diarrheagenic E. coli (DEC) pathotypes has not been studied captive peccary. This study aimed prevalence DEC, susceptibility antibiotics, frequency β-lactamase genes (ESBL) faeces. DEC strain...

Objective(s) Different types of extended spectrum beta-lactamases (ESBLs) are encountered in the clinical settings worldwide. There are a few studies regarding the prevalence of ESBL genes among Klebsiella pneumoniae isolates at Tehran especially those of blaPER and blaCTX. The aim of this study was to determine the prevalence of blaSHV, blaTEM ,blaPER and blaCTX genes among clinical K. pneumo...

Background & Aims: The production of extended-spectrum-β-lactamases (ESBLs) is the main mechanism of resistance to β-lactam antibiotics. The outbreak of isolates simultaneously possessing several resistance mechanisms to β-lactam antibiotics caused a decrease in sensitivity of the confirmatory tests for ESBL. The aim of this study was the evaluation of the β-lactamase disk test method in the de...
