Sorbitol-bile salts broth was modified by the addition of 0.5% peptone for the enrichment of Yersinia enterocolitica in nonfood samples. A quantitative comparison was made of the growth of Y. enterocolitica in sorbitol-bile salts broth and peptone-sorbitol-bile salts broth at 22 degrees C. Incubation for 48 h resulted in an average 7.79 log10 increase in a viable cell number for six serotypes w...

Whereas cholesterol accounts for more than 90-95% of the sterols in bile, bile acids and their salts are the most important solutes; they are essential in the management of cholesterol levels and themselves help determine the extent of bile flow. Bile acids are synthesized from cholesterol in the liver. There are three groups. Primary bile acids, in humans mainly cholic and chenodeoxycholic aci...

Salmonella and Shigella bacteria require the type III secretion system (T3SS) to inject virulence proteins into their hosts and initiate infections. The tip proteins SipD and IpaD are critical components of the Salmonella and Shigella T3SS, respectively. Recently, SipD and IpaD have been shown to interact with bile salts, which are enriched in the intestines, and are hypothesized to act as envi...

Bile salts present in gallbladder of wild and cultured red seabream, Pagrosomus major, a marine teleost were analyzed. The bile from wild red seabream was found to contain two previously unknown bile salts along with two known bile salts, taurocholate and taurochenodeoxycholate. Isolation of each bile salt was performed by column chromatography. Fast atom bombardment mass spectra of the unknown...

Cholesterol crystallization is a key step in gallstone formation and is influenced by numerous factors. Human bile contains various bile salts having different hydrophobicity and micelle-forming capacities, but the importance of lipid composition to bile metastability remains unclear. This study investigated the effect of bile salts on cholesterol crystallization in model bile (MB) systems. Sup...

this experiment was conducted to evaluate the effect of emulsifiers such as lecithin and bile salts onbroilers performances fed diet containing vegetable fats. 192 male ross broiler chickens were randomlyallocated in a factorial experiment design of 3 × 2, consisting two sources of fat (four percent fatty acidsor soy bean oil) and three emulsifiers (none, one percent lecithin and 0.05 percent b...

Bile from patients with mixed gallstones and controls without gallstones was analysed for relative concentrations of bile salts, phospholipids and cholesterol. A significant difference was found in the concentration of bile salts in normal controls and patients with cholelithiasis. The mean values for total bile salts, phospholipids and cholesterol in patients' bile were Mean + S.E. 84.34 + 15....

To study the mechanism of the propsed assimilation of cholesterol, we cultured various strains of Lactobacillus acidophilus and a Bifidobacterium sp. in the presence of cholesterol and oxgall. During culturing, both cholesterol and bile salts were precipitated. Because of bacterial bile salt deconjugation, no conjugated bile salts were observed in either the culture fluids or the pellets. Durin...

Bile salts are ionic amphiphilic compounds with a steroid skeleton. Among the most important physiological properties of bile salts are lipid transport by solubilization and transport of some drugs through hydrophobic barriers. Bile salts have been extensively studied to enhance transepithelial permeability for different marker molecules and drugs. They readily agglomerate at concentrations abo...
