In most countries, tuberculosis caused by Mycobacterium bovis is mainly a disease of cattle but can infect buffalos too. The disease can be controlled successfully by mean of a test-and-slaughter program. In Iran test-and-slaughter program has started since 1971 and prevalence of bovine tuberculosis reduces from 5% to less than 0.12% in recent years. In Western Azarbaijan, North West of Iran, t...

Enzootic bovine leukosis (EBL) is known as bovine lymphosarcoma and normally affects the old cattle. EBL is caused by bovine leukemia virus (BLV), which is generally spread all around the world. This virus is transmitted via bovine blood products within and between cattle herds. Glycoprotein GP51 in the blood is responsible for cattle immune responses to BLV. This virus has been previously dete...

Onion (Allium Cepa) contains high levels of flavonoids. Although there are many studies indicating the inhibitory effects of flavonoids on xanthine oxidase, there is no report on the effect of onion on this enzyme. Therefore, in the present study, the inhibitory effects of onion on xanthine oxidase are investigated. Fresh filtered juice of onion was prepared and its inhibitory effect on guine...

Background: The buffalo (Bubalus bubalis) is the animal with special production characteristics in producing milk and meat has a critical role in rural industry in Iran. The most problem of this specie is its low reproductive output. The aim of the present study was to evaluate the effect of bovine cumulus co-culture on maturation rate of Buffalo oocyte.Materials and Methods: Ovaries were colle...

Background: Genetic analysis in mice has lead to find about maternal effect genes such as Filia. Filia knock out mice have a 50% decrease in fertility. Filia dysfunction causes disorders in pre-implantation development. Mutations in human Filia gene, cause FBHM (Familial Biparental Hydatidiform Mole) in women. Filia protein in mice is homologous to that of rat and human, so this idea has emerge...

Bovine tuberculosis is an important worldwide disease mainly related to cattle, although it also affects other mammals, including humans. In recent years, there have been considerable advances in the knowledge of immune response mechanisms underlying interaction Mycobacterium bovis, main agent bovine tuberculosis, with its hosts. this review we describe most findings on cattle M. particularly r...

Multiphoton imaging and Raman spectroscopy reveal chemistry micro-structure of the bovine vertebral endplate.

Bovine lactoferrin (LTF) is a member of the transferrin family of iron-binding proteins. This protein is present in a wide variety of biological fluids and shows important physiological functions in body. In this study, 404 blood samples were collected from Holstein dairy farms in Iran. A 301 bp fragment of intron 6 in bovine LTF gene was amplified and the animals were genotyped using polymeras...

To determine the role of DDX3Y gene in spermatogenesis and infertility in bulls, blood samples were collected from five infertile bulls (azoospermic; no sperm in the semen) at the Animal Breeding Center in Karaj, Iran. The recommended human primers by EAA/EQMN were investigated using the BLASTn database for STS marker detection. Alignment of STS marker genes with bovine genome was performed. Pr...

Background: The present study aimed to investigate the presence of leptin mRNA transcript in epididymal spermatozoa of Holstein cattle by RT-PCR analysis. Materials and Methods: To collect sperm from epididymis, the whole testes of three adult Holstein bulls were quickly removed after slaughtering. Samples were transferred to the laboratory on ice and subsequently the epididymal contents were c...
