Pathogenic food-borne bacteria have been associated with severe morbidity and mortality in humans and animals. This study was aimed at determining the prevalence of Staphylococcus aureus, Salmonella spp., and Escherichia coli present in cattle and pigs slaughtered in selected abattoirs in Vhembe District and at determining the susceptibility of the isolates to antibiotics. A total of 176 swab s...

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...

Subclinical mastitis is a persistent problem in dairy farms worldwide. Environmental Escherichia coli is the bacterium predominantly responsible for this condition. In Thailand, subclinical mastitis in dairy cows is usually treated with various antibiotics, which could lead to antibiotic resistance in bacteria. E. coli is also a reservoir of many antibiotic resistance genes, which can be convey...

The mammalian gastrointestinal tract is colonized by a high-density polymicrobial community where bacteria compete for niches and resources. One key competition strategy includes cell contact-dependent mechanisms of interbacterial antagonism, such as the type VI secretion system (T6SS), a multiprotein needle-like apparatus that injects effector proteins into prokaryotic and/or eukaryotic target...

Medical and pharmacological communities have long searched for antimicrobial drugs that increase their effect when used in combination, an interaction known as synergism. These drug combinations, however, impose selective pressures in favour of multi-drug resistance and as a result, the benefit of synergy may be lost after only a few bacterial generations. Furthermore, there is experimental evi...

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...

conclusions the results showed that some patients were probably contaminated with nonbacterial and nonparasitic agents. all the parasitic isolates were resistant to most antibiotics. therefore determination of microbial isolates and antibiotic susceptibility is necessary before treatment procedures. results of 2376 patients, 466 (19.6%) were contaminated with pathogenic bacteria or protozoa.the...

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...
