Background: Increasing antimicrobial resistance (AMR) is a global threat and wild migratory birds may act as mediators of resistant bacteria across country borders. Our objective was to study extended-spectrum beta-lactamase (ESBL) plasmid-encoded AmpC (pAmpC) producing Escherichia coli in barnacle geese using whole genome sequencing (WGS) id...

A carbapenem-resistant Escherichia coli strain (DVR22) was recovered from a stool specimen from a patient with traveler's diarrhea who had traveled to India. Molecular screening led to the first identification of NDM-1 in Spain. The bla(NDM-1) gene was located in a conjugative plasmid of ca. 300 kb that also contained the bla(CTX-M-15), bla(TEM-1), Δbla(DHA-1), and armA genes. In addition, bla(...

کلی باسیلوز یک بیماری شایع در واحدهای پرورش مرغ های گوشتی بوده که بواسطه مقاومت باکتریائی و استفاده بی رویه از داروها طی سالیان متمادی تلفات و خسارات زیادی را به بار آورده است. هدف از مطالعه حاضر، بررسی وجود ژن های bla tem,   bla ctx-m و bla shv در نمونه های اشریشیا کلی جدا شده از طیور به روش multiplex-pcr و تعیین الگوی حساسیت آنتی بیوتیکی این سویه ها می باشد. در مجموع تعداد 60 جدایه اشریشیا کل...

In this study, we examined molecular mechanisms associated with multidrug resistance (MDR) in a collection of Escherichia coli isolates recovered from hospitalized animals in Ireland. PCR and DNA sequencing were used to identify genes associated with resistance. Class 1 integrons were prevalent (94.6%) and contained gene cassettes recognized previously and implicated mainly in resistance to ami...

Abstract Infection of the urinary tract ranks as one most common infections affecting people worldwide and its treatment is made complicated by rising incidence antibiotic resistance. This study aimed to detect extended spectrum beta-lactamase (ESBL) genes resistance profile uropathogenic Escherichia coli ( E. ) recovered from patients attending a University Teaching hospital in Nigeria. Uropat...

The incidence of extended-spectrum β-lactamases (ESBLs) has been increasing worldwide, but screening criteria for detection of ESBLs are not standardized for AmpC-producing Enterobacteriaceae such as Enterobacter species. In this study, we investigated the prevalence of ESBLs and/or AmpC β-lactamases in Japanese clinical isolates of Enterobacter spp. and the association of plasmid-mediated quin...

Here we report the nucleotide sequence of pCTX-M3, a highly conjugative plasmid that is responsible for the extensive spread of the gene coding for the CTX-M-3 extended-spectrum beta-lactamase in clinical populations of the family Enterobacteriaceae in Poland. The plasmid belongs to the IncL/M incompatibility group, is 89,468 bp in size, and carries 103 putative genes. Besides bla(CTX-M-3), it ...

The putative virulence and antimicrobial resistance gene contents of extended spectrum β-lactamase (ESBL)-positive E. coli (n=629) isolated between 2005 and 2009 from humans, animals and animal food products in Germany, The Netherlands and the UK were compared using a microarray approach to test the suitability of this approach with regard to determining their similarities. A selection of isola...

BACKGROUND AND OBJECTIVES Klebsiella pneumoniae, one of the important causes of nosocomial infections, is the most common extended spectrum β-lactamases (ESBLs) producing organism. ESBLs are defined as the enzymes capable of hydrolyzing oxyimino-cephalosporins, monobactams and carbapenems. The aims of this study were to identify ESBL-producing K. pneumoniae isolates and detect their antibiotic ...

Complete sequencing of pJIE137 revealed a backbone closely related to p271A, encoding a novel RepA protein but with a similar organization and up to ∼70% nucleotide identity to IncN plasmids. A region in pJIE137 resembling the IncN CUP regulon is mostly missing from p271A, presumably due to recombination. The class 1 In/Tn and ISEcp1-bla(CTX-M-62) transposition unit in pJIE137 and a putative tr...
