Ovine Enzootic Abortion (OEA): a comparison of antibody responses in vaccinated and naturally-infected swiss sheep over a two year period
BACKGROUND Prevention and control of ovine enzootic abortion (OEA) can be achieved by application of a live vaccine. In this study, five sheep flocks with different vaccination and infection status were serologically tested using a competitive enzyme-linked immunosorbent assay (cELISA) specific for Chlamydophila (Cp.) abortus over a two-year time period. RESULTS Sheep in Flock A with recent O...
متن کاملHumoral immune response against two surface antigens of Chlamydia pecorum in vaccinated and naturally infected sheep
Chlamydia pecorum is a globally recognised livestock pathogen due to the significant clinical and economic impact it poses to livestock producers. Routine serological diagnosis is through a complement fixation test (CFT), which is often criticised for cross-reactivity, poor sensitivity and specificity. Although serology remains the preferred method in veterinary diagnostic laboratories, serolog...
متن کاملDiagnosis and prevalence of ovine pulmonary adenocarcinoma in lung tissues of naturally infected farm sheep.
AIM This study was aimed to detect ovine pulmonary adenocarcinoma (OPA) in sheep flocks affected with pulmonary disorders at organized farm. MATERIALS AND METHODS A total of 75 sheep died naturally were thoroughly examined for the lesions of OPA during necropsy. Tissue sections from affected portion of the lungs from each animal were collected aseptically and divided into two parts; one each ...
متن کاملSurface envelope glycoprotein is B-lymphocyte immunodominant in sheep naturally infected with ovine progressive pneumonia virus.
The B-lymphocyte-immunodominant antigen involved in naturally ovine progressive pneumonia virus (OPPV)-infected mature sheep remains unknown. Therefore, the amount of antibody in sera from 10 naturally OPPV-infected sheep was evaluated by immunoprecipitation (IP) of the major viral proteins in [(35)S]methionine/cysteine-labeled OPPV (whole virus) lysate. Using an excess of OPPV proteins in whol...
متن کاملMorphopathological study of naturally occurring ovine pulmonary adenocarcinoma in sheep in Fars province, Iran
Ovine pulmonary adenocarcinoma (OPA) is a contagious and transmissible lung cancer of sheepresembling human bronchiolo-alveolar carcinoma. In the present study, lungs of 9400 sheep slaughtered inFars province, Iran were examined morphopathologically. The OPA was diagnosed in the lungs of 21(0.22%) out of 9400 sheep. Frequency of involvement of different lobes in the affected lungs was includeda...
