Enteropathogenic Escherichia coli (EPEC), atypical enteropathogenic E. coli, and Shiga toxin-producing E. coli differ in their virulence factor profiles, clinical manifestations, and prognosis, and they require different therapeutic measures. We developed and evaluated a robust multiplex PCR to identify these pathogroups based on sequences complementary to escV, bfpB, stx1, and stx2.

conclusions this study suggests that epec strains are important contributors to diarrhea in iranian children. because of the weakness of routine microbiological tests and poor specifity of serological tests, it is recommended that the epec strains are better detected by molecular methods. results the e. coli isolates were confirmed by the presence of the uida gene. the epec was diagnosed in 6 c...

Salmonella spp., Shigella spp., and Yersinia spp. are important enteropathogenic bacteria. Antibiotic treatment is normally indicated for infections caused by Shigella spp. and only in the case of severe infections for Salmonella and Yersinia. Studies from a number of countries have reported the development of resistance of these bacteria to certain antibiotics. The new quinolones, such as cipr...

Enteropathogenic Escherichia coli isolated from diarrheal children and adults were studied. Twenty-two OK groups were set up as enteropathogenic Eschericha to include : O26: K60, O28a, 28c : K73, O44: K74, O55: K59, O86: K61, O86: K62, O111: K58, O112a,112c : K66, 0119: K69, O124: K72, O125: K70, O126: K71, O127: K61, O86: K63, O128: K67, O136: K78, O143: Kx1, O144: Kx2, O146: K87, A-D (Alkales...

Enteropathogenic species Yersinia pseudotuberculosis and enterocolitica are of great importance worldwide due to their ability survive preserve pathogenic properties in biotic abiotic environments. They can cause sporadic flare-up diseases. Therefore, it is extremely important use modern methods diagnosing diseases caused by these pathogens.
 The article analyzes the laboratory diagnostics...

background and objectives: the therapeutic options for diseases caused by escherichia coli are limited. in this study we investigated the presence of virulence factors among enteropathogenic escherichia coli (epec) strains and their antibiotic resistance patterns. the isolates were also checked for the presence of class1 integrons and gene cassettes. materials and methods: this study included 7...

Bayesian analysis was used to estimate the pig's and herd's true prevalence of enteropathogenic Yersinia in serum samples collected from Finnish pig farms. The sensitivity and specificity of the diagnostic test were also estimated for the commercially available ELISA which is used for antibody detection against enteropathogenic Yersinia. The Bayesian analysis was performed in two steps; the fir...

The ability of Clostridium perfringens type C to cause human enteritis necroticans (EN) is attributed to beta toxin (CPB). However, many EN strains also express C. perfringens enterotoxin (CPE), suggesting that CPE could be another contributor to EN. Supporting this possibility, lysate supernatants from modified Duncan-Strong sporulation (MDS) medium cultures of three CPE-positive type C EN str...

The duodenal microflora was studied during the first week of diarrhoea in 40 infants with acute infectious diarrhoea of different aetiologies and compared with that in a convalescent group and a group in whom diarrhoea of known aetiology had persisted for more than 14 days after an acute onset. In the acute phase 16 of the 40 infants had more than 10(4) colony forming bacteria/ml, predominantly...
