AIM To study the role of intestinal flora in inflammatory bowel disease (IBD). METHODS The spatial organization of intestinal flora was investigated in normal mice and in two models of murine colitis using fluorescence in situ hybridization. RESULTS The murine small intestine was nearly bacteria-free. The normal colonic flora was organized in three distinct compartments (crypt, interlaced, ...

C. albicans triggers recurrent infections of the alimentary tract mucosa that result from biofilm growth. Although the ability of C. albicans to form a biofilm on abiotic surfaces has been well documented in recent years, no information exists on biofilms that form directly on mucosal surfaces. The objectives of this study were to characterize the structure and composition of Candida biofilms f...

The bacterial species Streptococcus mutans is known as the main cause of dental caries in humans. Therefore, much effort has focused on preventing oral colonization by this strain or clearing it from oral tissues. The oral cavity is colonized by several bacterial species that constitute the commensal oral flora, but none of these is able to interfere with the cariogenic properties of S. mutans....

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 To determine the conjunctival bacterial flora present in patients with Stevens-Johnson syndrome. METHODS A prospective study of the conjunctival bacterial flora was performed in 41 eyes of 22 patients with Stevens-Johnson syndrome. The information gathered included the patient's sex and age, the duration of disease, the cause of Stevens-Johnson syndrome, and treatments. Scrapings of...

Intensified aquaculture includes the use of antimicrobials for disease control. In contrast to the situation in livestock, Escherichia coli and enterococci are not part of the normal gastrointestinal flora of fish and shrimp and therefore not suitable indicators of antimicrobial resistance in seafood. In this study, the diversity and phenotypic characteristics of the bacterial flora in raw froz...

A prospective observational study was conducted at J. N. Medical College, Aligarh Muslim University, to compare the bacterial flora obtained from sequestrum culture and sinus track culture and to evaluate their antibiotic sensitivity. A total of 62 patients with chronic osteomyelitis were enrolled (38 males and 24 females). Sinus track cultures were done taking all aseptic precautions and the r...

Bacterial infection, especially with intestinal-type bacterial flora, is a common complication in patients with cirrhosis [1–4]. Spontaneous bacterial peritonitis (SBP), urinary tract infection, pneumonia, spontaneous bacterial empyema and bacteraemia are the most frequent infective complications in this group. The incidence of infection with Gram-positive cocci, in particular, has increased in...

prebiotic: a nondigestible food ingredient that benefits the host by selectively stimulating the favorable growth and/ or activity of 1 or more indigenous prebiotic bacteria. prebiotics can modify the intestinal flora and interact with the immune system of the host against specific pathogens. however clinical trials are currently limited and a beneficial effect of prebiotic in treatment acute d...

Introduction: Bacterial vaginosis is defined as change in the vaginal ecology characterized by replacement of lactobacilli by a variety of bacterial flora including anaerobes. The condition is diagnosed using Amsel Criteria. Ten to fifteen percent of cases do not improve on antibiotics, which encouraged the use of probiotics. Aim: To compare between the efficiency of probiotic vaginal tampons a...
