The present study was an attempt to raise hen egg yolk Ig (IgY) simultaneously directed against Salmonella Enteritidis (SE) and Salmonella Typhimurium (ST) in the same egg yolk. The immunopotentiating effect of 2 different adjuvants -- Freund's adjuvants (FA) and immunostimulating complexes matrix (IM) -- on antibody response was also evaluated. Bacterial outer membrane proteins (OMP) were sele...
In order to design a new Salmonella enterica vaccine, one needs to understand how naive and immune chickens interact differently when exposed to S. enterica. In this study we therefore determined the immune response of vaccinated and non-vaccinated chickens after intravenous infection with Salmonella enterica serovar Enteritidis (S. Enteritidis). Using flow cytometry we showed that 4 days post ...
A chicken 13K cDNA microarray was used to profile global gene expression after Salmonella enteritidis (SE) challenge of young chickens. Two F8 advanced intercross lines (AIL), broiler by Leghorn, and broiler by Fayoumi, were studied. Day-old chicks were orally inoculated with SE, and spleens were harvested at day 7 or 8 post-inoculation. The SE bacteria burden in the spleen was quantified. The ...
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...

background : young chickens are more susceptible to salmonella colonization than older ones that have developed resistance with age as native microflora become established. methods : in this study, two groups of fertile eggs were inoculated with 20 cfu of hila or parent strains of s . enteritidis . presence and number of salmonella cells inside the homogenized egg contents were determined on...
this study was an attempt to investigate the effect of teaching meta cognitive strategies on iranian intermediate efl students speaking proficiency. in this study the researcher has employed metacognitive strategies taken from brown (2000) to teach speaking strategies to number of participants. the participants were intermediate students of shokouh language institute; they were divided into an ...
