pasteurellosis of cattle and buffalo named as hemorrhagic septicemia (hs) is an acute and fatal disease causes by pasteurella multocida serotypes b2 and e2 in different countries. hs is occurred in all parts of the world except australia. economic importance of disease in asia is more than africa. bovine pasteurellosis is endemic in northern areas (gilan and mazandaran), west and east azarbayja...

The aim of this study was to identify the deficiency of uridine monophosphate synthase (DUMPS) and the complex vertebral malformation (CVM) in Iranian Holstein bulls. A total of 144 blood samples were prepared of Holstein bulls in Abbas Abad Animal Breeding Center and Ferdowsi University of Mashhad's Dairy Farm in Khorasan state of Iran. Genomic PCR-RFLP protocol was performed to amplify the po...

background: foot -and- mouth disease (fmd) is endemic in iran. molecular techniques for diagnosis of persistent infection or carrier animals have shown a potential ability to improve the detection of a low genome copy number in samples. objectives: the purpose of this study is to evaluate the frequency of foot and mouth disease viral carriers in slaughtered sheep in mashhad industrial abattoir ...

Historically, dwarfism was the major genetic defect in U.S. beef cattle. Aggressive culling and sire testing were used to minimize its prevalence; however, neither of these practices can eliminate a recessive genetic defect. We assembled a 4-generation pedigree to identify the mutation underlying dwarfism in American Angus cattle. An adaptation of the Elston-Steward algorithm was used to overco...

Huge livestock population of India is under threat by a large number of endemic infectious (bacterial, viral, and parasitic) diseases. These diseases are associated with high rates of morbidity and mortality, particularly in exotic and crossbred cattle. Beside morbidity and mortality, economic losses by these diseases occur through reduced fertility, production losses, etc. Some of the major in...

Band 3 deficiency with hereditary spherocytosis and hemolytic anemia in Japanese black cattle, band 3(Bov.Yamagata), is caused by a total lack of band 3 protein with an autosomal dominant inheritance. Genotyping for band 3 deficiency and sexing were successfully achieved in biopsied embryo cells with efficiencies of 98.4% and 97.4%, respectively. Transfer of the embryo that was determined as ho...

The authors studied the incidence of nasal and visceral schistosomosis in 300 male cattle that were slaughtered in 2001 at the Karnataka Meat and Poultry Marketing Corporation Limited abattoir in Bangalore, South India. The nasal and intestinal scrapings and their contents were screened for eggs and the nasal and visceral cuttings were examined for worms. Eggs of Schistosoma nasale and S. spind...

The factors that control fat deposition in adipose tissues are poorly understood. It is known that visceral adipose tissues display a range of biochemical properties that distinguish them from adipose tissues of subcutaneous origin. However, we have little information on gene expression, either in relation to fat deposition or on interspecies variation in fat deposition. The first step in this ...

Two point mutations were identified within the gene encoding bovine CD18 in a Holstein calf afflicted with leukocyte adhesion deficiency (LAD). One mutation causes an aspartic acid to glycine substitution at amino acid 128 (D128G) in the highly conserved extracellular region of this adhesion glycoprotein, a region where several mutations have been found to cause human LAD. The other mutation is...
