We report the cloning and analysis of a bovine JH locus comprising a DQ52 segment, six JH segments and sequence to a 5' H chain intronic enhancer. The contig was mapped to BTA 11 and evidence was found for rearrangement of the sixth JH segment at a low but detectable frequency. In contrast, the fourth segment present at a second copy of the bovine JH locus(More)
Neospora caninum, an apicomplexan protozoan parasite, is recognized as a major cause of abortion in cattle. Surface antigen 1 of N. caninum (NcSAG1) is an important immunodominant candidate for the development of a diagnostic reagent for neosporosis. The present study describes the development and evaluation of a latex agglutination test (LAT) with(More)
To confirm the diagnosis of the infectious pancreatic necrosis, the pancreas, liver, kidney and spleen specimens from 140 rainbow trout (Oncorhynchus mykiss) of weight ranges from 15 to 250 g were processed for routine histopathological and immunohistochemical (IHC) studies together with a nested-PCR using primers that amplify a 164-bp product. Of the 140(More)
The focus of present study was to determine the epidemiological and molecular aspects of different strains of cystic echinococcosis in Fars province, Iran. Liver and lung samples from 410 sheep, 206 goats and 315 cattle were collected. In cattle, the infestation rate was 18.1% (57/315), with 11.1% hepatic cysts and 7.0% pulmonary cysts. Out of all(More)
The diagnostic characteristics of immunohistochemistry (IHC) and polymerase chain reaction (PCR) methods were studied in the tissues of broiler chicken embryos experimentally infected by Neospora caninum. An infection with N. caninum NC-1 isolate was conducted in 70 broiler chicken embryonated eggs randomly divided into seven equal groups. After 8 days of(More)
Cattle are common intermediate hosts of Sarcocystis, and the prevalence in adult bovine muscle is close to 100 % in most regions of the world. Three Sarcocystis spp. are known to infect cattle as intermediate hosts, namely, S. cruzi, S. hirsuta, and S. hominis. The aim of the present study was the molecular identification and differentiation of these three(More)
