AIM The aim of the present study was to diagnose infectious bursal disease (IBD) using gross, histopathological, and immunopathological approaches and to compare efficacy of immunohistochemical techniques with conventional diagnostic techniques. MATERIALS AND METHODS A total of 33 samples were collected from the six different poultry farms from Ludhiana and the nearby districts. Upon gross an...

s of papers 3 7 Non-MHC alloantigen genes affecting immunity. W. E. Briles*, Northern Illinois University, DeKalb, IL 60115. An alloantigen is a genetically determined cell-surface molecule detected by specific antisera. An identifying letter has been assigned to each genetic locus responsible for the eleven distinct families of alloantigens A, C, D, E, H, I, J, K, L, P, and R. The genes of eac...

Developmental changes in immunocompetent cells of the gut during the first week posthatch were determined in broiler chicks fed immunobiotic lactic acid bacteria in the form of Lactobacillus jensenii TL2937-, Lactobacillus gasseri JCM1131(T)-, Lactobacillus delbrueckii ssp. bulgaricus NIAIB6-, or L. gasseri TL2919-supplemented diets. The relative weights of spleen and bursa of Fabricius in chic...

OBJECTIVE To evaluate effects of subacromial bursa injection with steroid according to dosage and to investigate whether hyaluronidase can reduce steroid dosage. METHODS Thirty patients with periarticular shoulder disorder were assigned to receive subacromial bursa injection once a week for two consecutive weeks. Ten patients (group A) underwent subacromial bursa injection with triamcinolone ...

F(1) hybrid chicks isogenic for the strong B histocompatibility locus and for most weak H-loci were X-irradiated on day 1 after hatching, injected intraperitoneally on day 2 with dispersed cells of bursa, spleen, or thymus from 4- or 10-wk-old F(1) hybrid donors, and immediately challenged by the same route with either Brucella abortus, sheep erythrocytes, or a mixture of both together. The agg...

Small shoot bud galls induced by the Fergusobia (Nematoda: Neotylenchidae)/Fergusonina (Diptera: Fergusoninidae) mutualism occur on various Eucalyptus spp. Four new species of Fergusobia, collected from small shoot bud galls on Eucalyptus camaldulensis, E. gomphocephala and E. leucoxylon, are described. Fergusobia gomphocephalae Davies n. sp. is morphologically characterized by a combination of...

This study investigated the effects of dietary resveratrol at 0, 200, 400, or 600 mg/kg of diet on the performance, immune organ growth index, serum parameters, and expression levels of heat shock protein (Hsp) 27, Hsp70, and Hsp90 mRNA in the bursa of Fabricius, thymus, and spleen of 42-d-old female black-boned chickens exposed to heat stress at 37 ± 2°C for 15 d. The results showed that heat ...
