Two lactic acid-producing bacteria, one volatile fatty acid-producing bacterium, and one starch-hydrolyzing bacterium were isolated from the cecal contents of adult chickens. The ability of these bacteria to produce lactic and volatile fatty acids in

Competitive exclusion bacteria must colonize the intestinal tract of the chicken in order to protect the chicken from colonization by Salmonella. Typically, these beneficial bacteria are introduced into the gut by ingestion as the chick preens after

During the first week post-hatch, chickens demonstrate an increased susceptibility to infection by bacteria such as Salmonella. The purpose of the present study was to evaluate the effects of immune lymphokines on phagocytosis and killing activities

Until recently the only biomedical use of erythrocytes was in transfusion medicine to restore a normal oxygen delivery. The development of a technology that permits one to open and reseal erythrocytes has dramatically changed this perspective. Curren

Broiler breeder flocks and hatcheries have been identified as reservoirs of salmonellae and potential sources of Salmonella infection for highly susceptible day-old chicks. Once salmonellae have colonized the gastrointestinal tract of the chick, the

Chicks are most susceptible to Salmonella infection during the first 4 days post-hatch. In poultry, one of the primary cells in the innate immune response to early bacterial invasion by Salmonella is the heterophil. Previous studies using a granulocy
