We investigated the prevalence of the virulence genes specific for five major pathogroups of diarrheagenic Escherichia coli (DEC) in primary cultures from feces of animals slaughtered for human consumption in Burkina Faso. For the study, 704 feces samples were collected from cattle (n = 304), chickens (n = 350), and pigs (n = 50) during carcass processing. The presence of the virulence-associat...

Escherichia coli is a normal inhabitant of the gastrointestinal tract of all warm-blooded animals, but variants of this species is also among the important etiological agents of enteritis and several extraintestinal diseases. The E. coli strains that cause diarrhoeal illness are categorised into pathogenicity groups based on virulence properties, mechanisms of pathogenicity, clinical symptoms a...

conclusions etec and eaggec were the most detected e. coli among stool and uti samples, emphasizing the need to dedicate more health care attention to this group. in addition, our phylogenetic study may be helpful in figuring out the infection origin and for epidemiological studies. nonetheless, more research studies with larger sample sizes are suggested for confirming our results. results ove...

Escherichia coli has been implicated as one of the main etiological agents diarrhea, urinary tract infections, meningitis and septicemia worldwide. The ability to cause diseases is potentiated by presence virulence factors. factors influence capacity E. infect colonize different body systems. Thus, pathogenic are grouped into DEC strains that mainly clustered in phylogenetic group B1 A; ExPEC b...

The present study carried out to evaluate the presence of diarrheagenic Escherichia as causes of diarrhea in young calves in Damietta governorate during period from November 2015 to March 2016. Bacteriological examination was done on a total of (100) fecal samples collected from young diarrhoeic calves of average age of 2 to 21 days to detect the prevalence of E. coli . The samples were grouped...

Cattle farming can promote diarrheal disease transmission through waste, effluents or cattle fecal matter. The study aims to characterize the diarrheagenic Escherichia coli (DEC) isolated from cattle feces, manure in the composting process and slurry, collected from four cattle markets in Ouagadougou. A total of 585 samples (340 cattle feces, 200 slurries and 45 manures in the composting proces...

Diarrhea can be caused by a range of pathogens, including several bacteria. Conventional diagnostic methods, such as culture, biochemical tests, and enzyme-linked immunosorbent assay (ELISA), are laborious. We developed a 7-plex PCR-Luminex assay to simultaneously screen for several of the major diarrhea-causing bacteria directly in fecal specimens, including pathogenic Aeromonas, Campylobacter...

BACKGROUND The German Military Medical Service contributed to the medical screening of unaccompanied minor refugees (UMRs) coming to Germany in 2014 and 2015. In this study, a broad range of diagnostic procedures was applied to identify microorganisms with clinical or public health significance. Previously, those tests had only been used to screen soldiers returning from tropical deployments. T...

In a prospective study between July 1999 and September 2000, stool specimens of children below the age of 16 years with (n = 187) and without (n = 137) diarrhea were tested for the presence of enterovirulent bacteria by standard culture methods and by PCR. Targets for the PCR were the plasmid pCVD432 for enteroaggregative Escherichia coli (EAEC), the verotoxin 1 and verotoxin 2 genes for entero...
