Four human Lactobacillus acidophilus strains were tested for their ability to adhere onto human enterocyte like Caco-2 cells in culture. The LA 1 strain exhibited a high calcium independent adhesive property. This adhesion onto Caco-2 cells required a proteinaceous adhesion promoting factor, which was present in the spent bacterial broth culture supernatant. LA 1 strain also strongly bound to t...

INTRODUCTION Escherichia coli causes gastroenteritis in humans and animals. CASE PRESENTATION In this study, both Shiga toxin-producing E. coli (STEC) and atypical enteropathogenic E. coli (EPEC) strains were identified in a stool sample from a healthy child, and they were serotyped as Shiga toxin-producing E. coli (STEC) ONT : H19 and atypical enteropathogenic E. coli (EPEC) O37 : H45. CON...

Bacterial plasmids are self-replicating, extrachromosomal elements that are key agents of change in microbial populations. They promote the dissemination of a variety of traits, including virulence, enhanced fitness, resistance to antimicrobial agents, and metabolism of rare substances. Escherichia coli, perhaps the most studied of microorganisms, has been found to possess a variety of plasmid ...

During recent years, interest in the use of bacteriophages as biocontrol agents against foodborne pathogens has increased, particularly for members of the family Enterobacteriaceae, with pathogenic Escherichia coli, Shigella, and Salmonella strains among them. Here, we report the isolation and characterisation of 12 novel T5-like bacteriophages from confiscated food samples. All bacterophages e...

Schistosomiasis is a chronic enteropathogenic disease caused by blood flukes of the genus Schistosoma. The disease afflicts approximately 240 million individuals globally, causing approximately 70 million disability-adjusted life years lost. Chronic infections with morbidity and mortality occur as a result of granuloma formation in the intestine, liver, or in the case of Schistosoma haematobium...

Enteropathogenic bacteria was isolated from 131 of 447 (29.4%) neotropical Panamanian lizards belonging to 34 species of seven families. Overall, 147 strains of bacteria were isolated comprising 26 Salmonella and 10 Arizona serotypes. Gymnopthalmus speciosus had the highest infection rate, 12 of 13 individuals (92.3%), whereas Gonatodes fuscus exhibited the lowest, 1 of 18 (5.6%). The highest i...

Ribonucleotide reductase (RNR) is an essential enzyme for all living organisms since is the responsible for the last step in the synthesis of the four deoxyribonucleotides (dNTPs) necessary for DNA replication and repair. In this work, we have investigated the expression of the three-RNR classes (Ia, Ib and III) during Escherichia coli biofilm formation. We show the temporal and spatial importa...

OBJECTIVES To determine the relative frequencies and prevalence rates of pathogenic Escherichia coli and intestinal parasites in hospitalised infants (0-5 years) in Kumasi. DESIGN A prospective descriptive study of screening 162 (83 males and 79 females) infants with diarrhoea and 122(64 males and 58 females) non-diarrhoeal infants controls for pathogens (E. coli and intestinal parasites) by ...

OBJECTIVE To investigate the cause of infective diarrhea in children, special distribution of the infection and the drug sensitivity. PATIENTS AND METHODS We carried out pathogenic detection and drug sensitivity tests for one hundred and twenty-six children with diarrhea, including 67 children in infant group (0-<1 year) and 59 children in child group (1-5 years). RESULTS Fat particles and ...

The mucosa of the small intestine of neonatal calves responds in a similar way to a variety of infectious agents. However, samples should be removed under general anaesthesia to avoid post-mortem artefacts. These include the separation of epithelium from the villous lamina propria and denudation of villous tips within a few minutes of death, and occur more rapidly in challenged animals. Patholo...
