Molecular screening of ovine mastitis in different breeds

Screening of Breeding Bulls of Different Breeds through Karyotyping

A study of chromosomal analysis for 200 breeding bulls of different breeds of cattle (Jersey, Holstein Friesian, Sahiwal and Cross-bred) and Nili-Ravi buffalo, maintained at Semen Production Unit, Qadirabad and Livestock Experiment Station, Bhunikey (Pattoki) was carried out. Micromethod was adopted for leukocyte culture and chromosomes were trapped at metaphase stage. The diploid number of chr...

The prevalence of ovine herpesvirus-2 in 4 sheep breeds from different regions in South Africa.

About 90% of bovine malignant catarrhal fever (BMCF) PCR-positive cases in South Africa are caused by alcelaphine herpesvirus-1 (AlHV-1) and the other 10% by ovine herpesvirus-2 (OvHV-2). The prevalence of OvHV-2 in different sheep breeds in South Africa was determined in order to investigate whether the lower incidence of BMCF caused by OvHV-2 in comparison with AlHV-1 can be ascribed to a low...

Molecular identification of ovine Babesia spp. in north of Iran

Background: Babesia is blood-tissue parasite, which are transmitted by hard ticks from Ixodidae family. The parasite is the cause of Babesiosis among ruminants. Babesia is as one of main fatal factors among livestock in endemic regions such as Iran. The aim of this study was to investigate Babesia spp infection using microscopic and molecular methods among small ruminants in Mazandaran and Gole...

Study on Frequency, Aetiology and Some Enzymatic Activities of Subclinical Ovine Mastitis in Urmia

molecular and physiological characterizations of floral scent production in rosa damascena mill.

گل محمدی (r. damascena mill.)مهمترین گونه ای است که در تولید گلاب، عطر و اسانس، در صنعت عطرسازی و دارویی کاربرد دارد. با وجود اهمیت عطر گل محمدی، پژوهش های مولکولی و بیوشیمیایی عطر گل این گونه هنوز در مراحل ابتدایی است. در این پژوهش، ویژگی های مولکولی و فیزیولوژیکی تولید عطر در گل محمدی در آزمایش های مختلف مورد بررسی قرار گرفتند. در آزمایش اول، پژوهشی به منظور بررسی تنوع شیمیایی اسانس میان 44 ت...
