Urinary tract infections(UTIs) are among the most common bacterial infections encountered in clinical practice (Ejrnaes, 2011)) E.coli causes about 80%of acute UTIs(Mitsumori,1998).E.coli is the most prevalent facultative gram negative bacilli in the human fecal flora, usually inhabits the colon as an innocuous commensal (Johnson, 1991). E.coli strains causing disease outside the gastrointestin...

Sulfonamides are known to alter the intestinal flora of animals, with a consequent change in the synthesis of certain vitamins by the intestinal bacteria (l-5). This altered synthesis may in turn lead to an increased dietary vitamin requirement for some animals or invoke new requirements in others. For example, the inclusion of 1 per cent of sulfasuxidine in the diet of chicks increases their f...

It is well known that some intestinal bacteria, such as Escherichia coli, can produce a remarkable amount of molecular hydrogen (H(2)). Although the antioxidant effects of H(2) are well documented, the present study examined whether H(2) released from intestinally colonized bacteria could affect Concanavalin A (ConA)-induced mouse hepatitis. Systemic antibiotics significantly decreased the leve...

in this study, two main probiotics (lactobacillus plantarum and lactobacillus delbrueckii subsp. bulgaricus) were isolated from the intestine of tor grypus and their effects on growth performance, gut microbial flora and digestive enzymes activities (i.e., α-amylase, lipase, trypsin, chymotrypsin, and alkaline phosphatase) of tor grypus (karaman, 1971) were determined. juveniles of t. grypus (n...

Colorectal cancer is one of the most common human malignant tumors. Recent research has shown that colorectal cancer is a dysbacteriosis-induced disease; however, the role of intestinal bacteria in colorectal cancer is unclear. This review explores the role of intestinal flora in colorectal cancer. In total, 57 articles were included after identification and screening. The pertinent literature ...
