brucellosis is a zoonotic disease transmitted to humans either from animals or from their products.although brucellosis can be found worldwide, the mediterranean basin, south and central america, easterneurope, asia, africa, the caribbean, and the middle east have currently been listed as high-risk regions. thegenus brucella is classified in at least nine species. brucella melitensis is the glo...

  With advent and development of DNA recombinant technology and advantages of p. pastoris expression system, fusion (F) protein of PPRV expression, because of effective immunodominant role could be an appropriate candidate for production of recombinant vaccine against PPR disease. In this study, F gene of PPRV Nigeria 75/1 strain (1637 bp) was amplified using RT-PCR and purified. It was then cl...

This study was designed to identify genetically resistant animals to gastrointestinal nematode (GIN) infections using microsatellite polymorphisms of Ovar-DRB1 gene in Iranian Ghezel sheep breed lambs. In the present study 120 male Ghezel lambs were at 4 to 6 months of age randomly selected from six different sheep flocks in East Azerbaijan province (n=20 per flock). These lambs were naturally ...

Medicinal use of the opium poppy (Papaver somniferum L) has ancient history, but the isolation of morphine was not described until the early nineteenth century. Morphine is the most important alkaloid of opium poppy in the last 50 years. In the morphine pathway has been reported to generate morphine in this species, CODM has a crucial role as the gene coding the enzyme respons...

objective(s) staphylococcus aureus is a common cause of human infection, and emergence of vancomycin-resistance s. aureus  is a great concern for treatment of methicillin-resistant s. aureus,(mrsa) in recent years (mrsa). here, we report the isolation of high-level vrsa. materials and methods s. aureus was isolated from foot ulcer of a diabetic woman in tehran, iran. antibiotic susceptibility w...

rotaviruses group a are the major cause of diarrhea in calves under one month and every year causes enormous economic losses. serological and molecular techniques can be used for rapid detection of rotaviruses but virus isolation requires specific methods of cell culture and suitable cell lines. in this study, 41 samples were collected from diarrheal calves up to the age of one month, from indu...

Speciation with gene flow is greatly facilitated when traits subject to divergent selection also contribute to non-random mating. Such traits have been called 'magic traits', which could be interpreted to imply that they are rare, special, or unrealistic. Here, we question this assumption by illustrating that magic traits can be produced by a variety of mechanisms, including ones in which repro...
