The research materials are based on the processing and analyzing official results of air ground surveys conducted in 2019, providing departmental materials. habitats with a high number mountain sheep include Karaganda, Turkestan, Dzhambul Almaty regions Republic Kazakhstan. paper aims to estimate changes argali’s reveal basic influencing factors. total wild Kazakhstan is 17954 heads. shows that...
Melatonin is a pleiotropic molecule with variety of biological functions, which include its immunoregulatory action in mammals. Brucellosis worldwide endemic zoonotic disease caused by the Brucella, not only causes huge economic losses for livestock industry but also impacts human health. To target this problem, current study, two marker-free transgenic sheep overexpressing melatonin synthetic ...
The type strain of Listeria monocytogenes differs from wild-type L. monocytogenes strains in more characteristics than just the previously reported deficiency in hemolytic activity and virulence in the murine infection model. The type strain from the American Type Culture Collection (strain ATCC 15313) produces lecithinase, is hemolytic on rabbit (but not sheep) blood agar, lacks motility, and ...
Simultaneous infestation of 3-6 month-old Black-head sheep with 15 South African wild strains of Rhipicephalus evertsi evertsi males and females as well as a strain from Rwanda clearly showed that all strains are capable of inducing paralysis. Assessment of the infestation-rate of engorging female ticks during the period that their mass ranged between 15 and 21 mg/kg sheep body mass indicated t...
Transgenic sheep can be used to achieve genetic improvements in breeds and as an important large-animal model for biomedical research. In this study, we generated a TALEN plasmid specific for ovine MSTN and transfected it into fetal fibroblast cells of STH sheep. MSTN biallelic-KO somatic cells were selected as nuclear donor cells for SCNT. In total, cloned embryos were transferred into 37 reci...
Agouti signaling protein (ASIP) functions to regulate pigmentation in mice, while its role in many other animals and in humans has not been fully determined. In this study, we identify a 190-kb tandem duplication encompassing the ovine ASIP and AHCY coding regions and the ITCH promoter region as the genetic cause of white coat color of dominant white/tan (A(Wt)) agouti sheep. The duplication 5'...
