This research has performed for detection of Aspergillus species (A. fumigatus, A. flavus, A. niger and A. terreus) in aborted bovine, ovine, caprine and camel foetuses by real-time PCR in Iran. After modification of real-time PCR on abomasal contents, from the total number of 970 samples, 141 (14.53%) gave positive results for Aspergillus species. Of them, 62 (17.71%), 33 (14.04%), 27 (12.05%)...

Fresh cheese was prepared from caprine milk by isoelectric precipitation as a model experiment for reducing the allergenicity of milk. After acidic precipitation of casein, the beta-lactoglobulin content in curd was determined by ELISA using monoclonal antibody (MAb-beta209). The beta-lactoglobulin content was very high in the fresh cheese obtained from heat-treated (85 degrees C) bovine or cap...

BACKGROUND Type 1 diabetes mellitus is a devastating disease for which there is currently no cure, but only lifetime management. Islet xenotransplantation is a promising technique for the restoration of blood glucose control in patients with diabetes mellitus. The purpose of this study was to explore the potential use of caprine (goat) islet cells as xenogeneic grafts in the treatment for diabe...

Inducible nitric oxide synthase (iNOS) regulation in human and murine macrophages in vitro differs considerably. In this study, expression of macrophage iNOS in ruminants was addressed. Nitric oxide (NO) output by cattle and goat macrophages was as different as that by human and mouse macrophages. Bovine macrophages activated by heated Salmonella dublin or lipopolysaccharide (LPS) expressed hig...

There are several physiological and pharmacological evidences indicating that opening of voltage dependent Ca channels play a critical role in induction of acrosome reaction in mammalian sperm. We determined the intracellular free Ca concentration in ejaculated goat sperm using a fluorescent, Ca-specific probe, Fura2/AM, after the suspension of sperm in KRB medium, capable of sustaining capacit...

Neospora caninum is an obligate intracellular apicomplexan parasite that causes reproductive loss and severe economic losses in dairy and goat industry. In the present study, we aim to investigate the effects of N. caninum tachyzoites on the release of extracellular traps (ETs) in caprine monocytes and furthermore elucidated parts of its molecular mechanisms. N. caninum tachyzoite-induced monoc...

Mammalian sperm capacitation is an essential prerequisite to fertilization. Although progress is being made in understanding the physiology and biochemistry of capacitation, little has been yet explored about the potential role(s) of individual sperm cell protein during this process. Therefore elucidation of the role of different sperm proteins in the process of capacitation might be of great i...

in this study the genetic polymorphism of growth hormone (gh) gene as a candidate gene in livestock was investigated. blood samples were randomly collected from 34 alpine and 42 saanen goats. dna was extracted from blood samples and a 365 bp region of exon 5 of the gh genewas amplified by polymerase chain reaction (pcr). pcr products were analyzed using single strand conformation polymorphism (...

Competitive inhibition of hybridization between (125)I-labeled caprine arthritis-encephalitis viral RNA and homologous cDNA by heterologous viral RNA shows that the caprine retrovirus shares <20% genome sequence homology with visna and progressive pneumonia viruses. These viruses, however, are indistinguishable in immunodiffusion reactions involving the major structural protein (p28).
