mcr-1 identified in Avian Pathogenic Escherichia coli (APEC)
Antimicrobial resistance associated with colistin has emerged as a significant concern worldwide threatening the use of one of the most important antimicrobials for treating human disease. Here, we examined a collection (n = 980) of Avian Pathogenic Escherichia coli (APEC) isolated from poultry with colibacillosis from the US and internationally for the presence of mcr-1 and mcr-2, genes known ...
متن کاملAvian Pathogenic Escherichia coli (APEC) - an update on the control
Escherichia coli is a common inhabitant of the gastrointestinal tracts of humans and animals. Commensal E. coli, designated as nonpathogenic, are considered to be the majority. This microorganism can be divided into two large groups: pathogenic and commensal E. coli. The pathogenic group is characterized by two more pathotypes: diarrheagenic E. coli (DEC) (with eight subpathotypes) and extraint...

متن کاملSome Adhesins of Avian Pathogenic Escherichia Coli (apec) Isolated from Septicemic Poultry in Brazil
Three hundred and fifty strains of E. coli isolated from septicemic poultry from seven states of Brazil were examined for presence of nine adhesion-encoding genes, hemagglutination and adherence to chicken tracheal cells (in vitro). Analysis of the strains by colony hybridization tests demonstrated that 93.7% of the isolates were fim +, 17% pap+ and 5.7% were sfa+. The mannose sensitive fimbria...
متن کاملPrevalence of Avian Pathogenic Escherichia coli (APEC) Clone Harboring sfa Gene in Brazil
Escherichia coli sfa+ strains isolated from poultry were serotyped and characterized by polymerase chain reaction (PCR) and amplified fragment length polymorphism (AFLP). Isolates collected from 12 Brazilian poultry farms mostly belonged to serogroup O6, followed by serogroups O2, O8, O21, O46, O78, O88, O106, O111, and O143. Virulence genes associated were: iuc 90%, fim 86% neuS 60%, hly 34%, ...
