Directly after birth, bacteria commence to colonise the skin and the mucous membranes of the respiratory, urogenital and intestinal tract. With time, more or less complex bacterial ecosystems are established at various body surfaces, of which the normal intestinal microflora is the largest and most diverse. Thus, an adult individual harbours more than 400 bacterial species at this site. Most of...
this study evaluated the effects of drinking thyme essence (dte) (zero, 0.10, 0.15 and 0.20 ml/l) on growth performance, immune response and changing of intestinal bacterial population in broiler chickens. a total number of 500 day old male broiler chicks (ross 308), were randomly assigned to 4 treatments with 5 replicates and 25 chickens per each, based on a completely randomized design (crd)....
Maki, Leroy R. (University of Wyoming, Laramie), and Kay Picard. Normal intestinal flora of cattle fed high-roughage rations. J. Bacteriol. 89:1244-1249. 1965.-Intestinal bacteria were isolated from 15 cattle. Approximately 600 isolates were studied, and their presence and numbers in the duodenum, ileum, cecum, and colon were noted. Bacteria most frequently isolated from all parts of the intest...
Epithelial cells at all mucosal surfaces are potentially apposed to bacteria, particularly in the intestine. It is established that intestinal epithelial cells (IECs) represent an important barrier between lamina propria cells and the potentially harmful lumenal contents. In addition, IECs are important immunoeffector cells with the capacity to release cytokines, chemokines, and other molecules...
In order to test if the intestinal bacteria play an important role in antibacterial ability of earthworm, we chose Escherichia coli O157:H7, an anthropozoonosis pathogen, as a biological stressor and studied the change of intestinal bacteria community of earthworm by PCR-DGGE analysis. Results showed that the pathogen merely existed 1 3 days, then almost disappeared after through the earthworm’...
The role of the intestinal microbiota in human health is gaining more attention since clear changes in the composition of the intestinal bacteria or environment are seen in patients with inflammatory bowel disease, allergy, autoimmune disease, and some lifestyle-related illnesses. A healthy gut environment is regulated by the exquisite balance of intestinal microbiota, metabolites, and the host...
