A nested polymerase chain reaction (PCR) assay was used to detect early stages of Myxobolus cerebralis in caudal and adipose fin samples from rainbow trout (RT). To determine sensitivity, groups of 10 RT were exposed to 2,000 M. cerebralis triactinomyxons/fish for 1 hour at 15 degrees C and subsequently moved to clean recirculating water. Fish were held for 2 and 6 hours and 1, 2, 3, 5, 7, 10, ...

a rapid and sensitive reverse transcription polymerase chain reaction (rt-pcr) and nested-pcr were used to detect bovine viral diarrhea virus 1 (bvdv-1) in bull semen. selected primers could amplify a part of the 5´utr of the bvdv genome. a 294 bp dna fragment was amplified and specificity of the results was confirmed by direct sequencing of the pcr product. prior to rna extraction, the seminal...

objective: chronic myeloid leukemia (cml) is a malignant clonal disorder of hematopoietic stem cells which results in increase of myeloid cells, erythroid cells and platelets in the peripheral blood and hyperplasia in bone marrow. investigations have shown different types of bcr- abl variants in these patients. in iran only 3 types of these variants have been identified because most of the clin...

AIMS The aim of this study was to compare the performance of four TaqMan RT-PCR assays with a commonly used nested RT-PCR and to include the Feline calicivirus (FCV) as an internal control. METHODS AND RESULTS RNA extracted from 87 swine faecal samples and 103 swine blood samples was subjected to different detection systems. Faecal samples naturally contaminated with Hepatitis E virus (HEV) a...

Group A rotavirus has been recognized as the major etiological agent of diarrhoea in calves, which leads to heavy economic loss to dairy farmers. The present study was done to estimate the prevalence along with genotypic characterization of group A rotavirus circulating in dairy herds of Punjab. A total of 198 faecal samples of cow calves were analyzed from April 2012 to March 2013 in Ludhiana ...
