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...

Worldwide, there are a large number of retailers in popular markets offering fresh orange juice, which is preferred for its nutritional and health value. Incorrect management during the preparation, presence pests, inadequate environmental conditions can affect microbiological quality juices sold even make them reservoir enteropathogenic bacteria. The aim this study was to evaluate bacteria fre...

The Portulaca oleracea L. (P. oleracea) has been used to treat bacillary dysentery for thousands of years in China. Pharmacology studies on P. oleracea have also showed its significant antibacterial effects on the enteropathogenic bacteria, which might reveal the treatment of P. oleracea in cases of bacillary dysentery to some extent. To date, however, the therapeutic basis of P. oleracea treat...

Lactobacilli were isolated from chicken gastrointestinal tract and examined for their potentially probiotic properties towards their inhibitory activity against poultry enteropathogenic bacteria. Biochemical tests, ITS-PCR and cell wall protein analysis were used to characterize the Lactobacillus isolates. The identification of isolated Lactobacillus strains based on phenotypic properties was n...

The pathogenicity of classical enteropathogenic Escherichia coli strains of human origin was investigated in gnotobiotic piglets. One to two day old piglets in groups of four were infected perorally with approximately 10(8) colony forming units of one of eight enteropathogenic E coli strains or a non-pathogenic control strain. Animals were necropsied 24 or 48 hours after infection and their int...

acute infectious gastroenteritis is one of the most common infectious diseases of humans in the world. diarrheal disease still ranks very high as a major cause of illness and death especially in developing nations. this study has been carried out to investigate enteropathogenic bacteria isolated from 2517 specimens of patients with diarrhea. the results obtained are as follow: salmonella typhim...

Type III secretion systems (T3SSs) are employed by Gram-negative bacteria to deliver effector proteins into the cytoplasm of infected host cells. Enteropathogenic Escherichia coli use a T3SS to deliver effector proteins that result in the creation of the attaching and effacing lesions. The genome sequence of the Escherichia coli pathotype O157:H7 revealed the existence of a gene cluster encodin...
