ABSTRACT Background and Objectives: Cryptosporidium parvum is a coccidian protozoan that causes diarrhea in immunocompromised humans and newborn animals. The severity of the disease depends on the immunological status of the affected. Cryptosporiosis can have lethal effects on immunocompromised individuals such as AIDS patients. About 10% of...
abstract this study was carried out to compare disinfecting effects of nanosilver with other feed disinfectants on layer hen performance, immune system, gastrointestinal microflora and intestinal morphology. total of 90 layers (lsl) were divided into five groups consisting: 1-control, 2- formalin (200 ppm), 3- formaycin (200 ppm), 4- nanosilver in drinking water (7.5 ppm) and 5-nanosilver in f...
BACKGROUND Allergy to hen's egg and meat contributes significantly to the manifestations of food allergy all over the world. OBJECTIVES This study was performed to assess the presence of hen's egg and meat specific IgE antibodies among patients investigated for various allergic disorders. METHODS This is a retrospective study performed at King Khalid University Hosptial, Riyadh. Data from 4...
an experiment was conducted to evaluate the effect of dietary crude protein and lysine levels on quality and quantity of egg production. fifteen diets consisted of 3 levels of protein (14, 15 and 16%) and 5 levels of lysine (0.71, 0.74, 0.77, 0.80 and 0.83 %) in a 35 factorial arrangement were provided. each diet was randomly fed to 4 replicates of 12 birds, during four periods of 4 weeks (28-...
Avibacterium paragallinarum is Gram-negative bacteria that cause infectious coryza (IC), an acute respiratory disease of chickens. Despite vaccination of Layer and breeder farms of Iran against IC, they are still experiencing the disease clinically and there is no knowledge of serotypes prevalence of this bacterium in this country. This study designed to determine serovar identity by molecular ...
objective: the purpose of the study was to evaluate the production of antibodies in serum as well as egg yolk raised against s. typhimurium and the cross-reactivity of this antibody with other enteric bacteria. materials and methods: white egg–laying hens were immunized with s. typhimurium, heat-killed whole cell, in freund's adjuvant. immunization was done with 107 conlony forming unit (cfu) o...
Wheat distillers dried grains with solubles (WDDGS) is a by-product that can be an alternative feed ingredient for poultry. However, WDDGS contains non-starch polysaccharides which limit its dietary inclusion. The objective of the current experiment was to evaluate the effect of WDDGS with or without Endofeed W® as a commercial enzyme on laying hens. A 5×2 factorial arrangement in a completely ...
BACKGROUND Children with allergy to raw egg white might tolerate low amounts of heated egg. Ovomucoid-specific IgE antibodies have been suggested to be predictors of whether children could tolerate heat-treated egg. OBJECTIVE The aim was to evaluate the clinical usefulness and added diagnostic value of measurements of IgE antibodies to egg white, ovalbumin, and ovomucoid in children with egg ...
Vibrio spp. are major causes of mortality in white shrimp (Litopenaeus vannamei) which is lacking adaptive immunity. Passive immunization with a specific egg yolk antibody (IgY) is a potential method for the protection of shrimp against vibriosis. In this study, immune effects of the specific egg yolk powders (IgY) against both V. harveyi and V. parahaemolyticus on white shrimp were evaluated. ...
