Comparison of virulence gene profiles of Escherichia coli strains isolated from healthy and diarrheic swine.
A combination of uni- and multiplex PCR assays targeting 58 virulence genes (VGs) associated with Escherichia coli strains causing intestinal and extraintestinal disease in humans and other mammals was used to analyze the VG repertoire of 23 commensal E. coli isolates from healthy pigs and 52 clinical isolates associated with porcine neonatal diarrhea (ND) and postweaning diarrhea (PWD). The re...
متن کاملFrequency of selected virulence-associated genes in intestinal and extra-intestinal Escherichia coli isolates from chicken
Background: Although Escherichia coli (E. coli)is a part of intestinal normal microflora of warm-blooded animals, includingpoultry, outbreaks occur in poultry raised below standard sanitation and duringthe course of respiratory or immunosuppressive diseases. Avian pathogenic E.coli (APEC) harbors several genes associated with virulence andpathogenicity. APEC strains are responsible for some dis...
متن کاملSerotypes and virulence profiles of non-O157 Shiga toxin-producing Escherichia coli isolates from bovine farms.
Non-O157 Shiga toxin-producing Escherichia coli (STEC) strains are clinically significant food-borne pathogens. However, there is a dearth of information on serotype prevalence and virulence gene distribution, data essential for the development of public health protection monitoring and control activities for the meat and dairy industries. Thus, the objective of this study was to examine the pr...
متن کاملPlasmid Profiles of Multidrug-resistant Escherichia coli from Clinically Healthy Swine
A total of 145 Escherichia coli isolates originated from clinically-healthy pigs were analyzed for plasmid profiles. All but one isolate (n=144) carried one to nine plasmids with size ranging from 0.7-16.2 Mda. Fifty-six plasmid profiles were defined based on sizes and numbers of plasmids in each strain, of which the most common patterns were 15.8, 4, 3.3, 1.7, 1.3 Mda and 16.2, 15.8, 4, 3.3, 2...
متن کاملPhylogenetic diversity, antimicrobial susceptibility and virulence gene profiles of Brachyspira hyodysenteriae isolates from pigs in Germany
Swine dysentery (SD) is an economically important diarrheal disease in pigs caused by different strongly hemolytic Brachyspira (B.) species, such as B. hyodysenteriae, B. suanatina and B. hampsonii. Possible associations of epidemiologic data, such as multilocus sequence types (STs) to virulence gene profiles and antimicrobial susceptibility are rather scarce, particularly for B. hyodysenteriae...
