urinary tract infections (utis) are significant health problem, with escherichia coli as the primary pathogen in proximally 80% of cases. the adhesion of e coli to the host cell can be influenced by cell surface hydrophobicity (csh) and is an important factor for the development of infections. this study was conducted to find the relation between csh and one of the adhesions (mannose resistant ...

The normal bacterial flora contains antibiotic resistance genes to various degrees, even in individuals with no history of exposure to commercially prepared antibiotics. Several factors seem to increase the number of antibiotic-resistant bacteria in feces. One important factor is the exposure of the intestinal flora to antibacterial drugs. Antibiotics used as feed additives seem to play an impo...

objective: vancomycin-resistant enterococci (vre) have emerged worldwide and have become an increasing problem in clinical settings. acquired glycopeptide resistance in enterococcus species is due to the acquisition of van a, van b, van d, van c and van e genes, resulting in the production of peptidoglycan precursors with reduced affinity for glycopeptide antibiotics. the origin of these van ge...

Microorganisms are a necessary part of everyday life. Many, known as resident or normal flora, adapt and live peacefully with the human body, providing benefits such as vitamin production or cellulose digestion in the intestines, and protection from disease-producing pathogens. Transient flora may stay for weeks to months but do not remain permanently because of fierce competition from resident...

The nature and magnitude of fluid and electrolyte loss into the small intestine were defined by the marker perfusion technique in patients with acute undifferentiated diarrhea (AUD) in the tropics. The patients were divided into two groups according to their small bowel bacteriologic findings, namely those with a predominant Escherichia coli flora and those with a mixed flora. 11 normal subject...

Antibiotic-resistant strains of Escherichia coli and, to a lesser extent, Klebsiella-Enterobacter were common in serial samples of the normal intestinal flora of healthy young adults in Thailand, and the resistance often was to multiple drugs and was transferable. Antibiotic administration promoted dominance of the flora by drug-resistant organisms regardless of the drug regimen and the predrug...
