Measurements of the heterophil:lymphocyte (H/L) ratio (invasive technique) and corticosterone in yolk and albumen (noninvasive techniques) were used to measure stress in 3 commercial laying strains, Lohmann White (LW), H&N White (HN), Lohmann Brown (LB), and a noncommercial cross (CR) between Rhode Island Red (male) and Barred Plymouth Rock (female), kept in conventional cages or floor pens. Al...

Pro-inflammatory cytokines are produced as part of innate immunity. Increased resistance to extraintestinal Salmonella enteritidis (SE) has been associated with an increase in heterophil pro-inflammatory cytokine gene expression. Invasion of chicken epithelial cells by SE induces an 8- to 10-fold increase in interleukin (IL) -6 production. Infection with SE induces an influx of heterophils to t...

The immune adherence hemagglutination assay was found to be as sensitive and specific as the indirect immunofluorescence technique for titration of antibodies to Epstein-Barr virus capsid antigen. Satisfactory virus capsid antigen-specific and negative control antigens for the immune adherence hemagglutination assay were prepared from cell extracts of the Epstein-Barr virus producer P3HR-1 and ...

ABSTRACT The effects of vitamins E and C supplementation on growth performance biochemical haematological parameters Japanese quail were studied. A total 360 one-day-old female quails randomly allocated to nine dietary treatment groups (10 birds per replicate 4 replicates treatment), including a control (basal diet) the basal diet supplemented with: 250 or 500 mg/kg vitamin C, E, both C. Vitami...

ENCEPHALITIS and cerebellar ataxia are rare complications of infectious mononucleosis (IM). Until recently the demonstration of a raised titre of heterophil antibodies in a Paul-Bunnell test provided the best objective data for substantiating a diagnosis of IM. Unfortunately, this test may produce both false positive and false negative results and may remain positive for many months after the a...

We evaluated serial enzyme and bilirubin determinations as aids to diagnosis of Epstein-Barr virus-induced infectious mononucleosis (121 cases) and the heterophil-negative mononucleosis-like illness due to cytomegalovirus (33 cases). Laboratory evidence for either type of mononucleosis includes mild to moderate hepatic dysfunction, with aspartate aminotransferase activity increased, but lower t...

an experiment was conducted in which 30 broiler chickens were selected based on their ecg and designated as healthy or subclinical ascites. subsequently, blood samples were collected and assayed for hemoglobin, hematocrit and differential leukocyte count. finally, all the birds were euthanized and their hearts harvested for the ventricle cuts. results indicated that broilers with subclinical as...

The present study was carried out to the effect of Spirulina supplementation on growth and some physiological performances Gimmizah males exposed heat stress (HS). A total number 150 male 4 weeks old were randomly allocated in five groups (3 replicates, 10 chicks each). first (positive control, PC) reared under 22-24OC PH 45-55% fed unsupplied basal diet, B). Whereas, other reused HS (38°C±1; 5...
