Accession Number. U15731. Species. Bos taurus. Origin of Clone. Hybridizing with a 220-bp cDNA of the somatotropin receptor (Hauser et al., 1990) 10 clones were identified from a bovine genomic library (EMBL3 SP6pT7 cloning vector; Clontech Laboratories, Palo Alto, CA). A 2.9-kb XhoIIAatII fragment containing the promoter and exon I was subcloned into pGEM-7Zf (Promega, Madison, WI), and both s...

Recent findings from this laboratory suggest that the biological actions of placental lactogen (PL) in mammalian fetal tissues are mediated through binding of the hormone to a distinct and unique PL receptor. We have now purified this receptor from fetal and maternal sheep liver, characterized its binding to PL, growth hormone (GH), and prolactin (PRL), and determined its molecular weight by SD...

Staphylococcus aureus is an important pathogen of many species, including sheep, and impacts on both human and animal health, animal welfare, and farm productivity. Here we present the widest global diversity study of ovine-associated S. aureus to date. We analysed 97 S. aureus isolates from sheep and sheep products from the UK, Turkey, France, Norway, Australia, Canada and the USA using multil...

The first category includes endemic African diseases which have evolved with and cycle in the various indigenous wildlife populations which, in turn, act as sylvatic reservoirs of the infectious agents. These diseases usually cause only minimal debility or mortality in indigenous wildlife and the infections are often subclinical. In contrast, infection of domestic livestock with these agents us...
