The use of biologically active substances tissue origin for the creation additives and immunomodulatory drugs is an important area scientific research in field nutrition pharmacology. aim work to evaluate effect enzymatic hydrolysate from fabricium bag broiler chickens on cytotoxicity nonspecific immunity mice against background experimental salmonella infection using biotechnological methods. ...

Salmonella vaccines used in poultry in the EU are based on attenuated strains of either Salmonella serovar Enteritidis or Typhimurium which results in a decrease in S. Enteritidis and S. Typhimurium but may allow other Salmonella serovars to fill an empty ecological niche. In this study we were therefore interested in the early interactions of chicken immune system with S. Infantis compared to ...

background: cryptosporidium parvum is a parasitic protozoan that functions as important causa­tive agent of diarrhea in human and animals. the host's immune response to surface anti­gens of c. parvum has been previously demonstrated. in this respect, the role of humoral immu­nity in the development of host protective immunity against this protozoon has been well demon­strated. methods: the effe...

Salmonella food poisoning is a public health problem. Feed withdrawal from broiler chickens before slaughter can favor the multiplication of Salmonella in the cecum and crop of contaminated animals and subsequently lead to contamination of carcasses in the processing plant. In the present study, a cocktail of lytic bacteriophages isolated from sewage water was orally administered to 45-d-old br...

Aim: To conduct detailed pathomicrobial studies on Salmonella Gallinarum infection in broiler chickens. Materials and Methods: Bacteriological and pathological studies were conducted on 134 dead poultry birds collected from 23 different farms suspected to be infected with S. Gallinarum. Results: Mortality pattern revealed that maximum mortality occurred in 1-2 week aged birds. Out of 23 Salmone...

Besides infection in humans, Salmonella enteritidis can also cause serious illness in young chickens. However, the genetic and immunological parameters important for the disease in chickens are not well characterized. In this study, processes in the chicken intestine in response to a Salmonella infection were investigated in two different chicken lines. One-day-old chickens were orally infected...

BACKGROUND Infection of newly hatched chicks with Salmonella enterica serovar Enteritidis (S. Enteritidis) results in an inflammatory response in the intestinal tract which may influence the composition of gut microbiota. In this study we were therefore interested whether S. Enteritidis induced inflammation results in changes in the cecal microbiota. To reach this aim, we compared the cecal mic...

Introduction: Salmonella has been significant cause of food poisoning in humans and contaminated eggs and chickens have been thought to be an important source of its infection. The use of Lactic acid bacteria (LAB) has been suggested as an effective strategy to reduce salmonella infection in poultry industry. In this study we tested Lactic acid bacteria isolated from Korean fermented foods for ...

Gallinacins in poultry are functional equivalents of mammalian beta-defensins, which constitute an integral component of the innate immune system. Salmonella enterica serovar Enteritidis is a gram-negative bacterium that negatively affects both human and animal health. To analyze the association of genetic variations of the gallinacin genes with the phenotypic response to S. enterica serovar En...
