Exploring Potential Bioactive Peptides in Fermented Bactrian Camel's Milk and Mare's Milk Made by Mongolian Nomads.

To date, bioactive proteins and peptides from minor livestock milks and their fermented products have been scarcely reported. In Mongolia, nomads are commonly rearing five livestock animal species (i.e.

Identification of sialyl oligosaccharides including an oligosaccharide nucleotide in colostrum of an addax (Addax nasomaculatus) (Subfamily Antelopinae).

Mammalian milk/colostrum usually contains milk oligosaccharides along with the predominant lactose. Although milk oligosaccharides of a variety of Bovidae species including cow, sheep and goat have been characterized, those of the addax, an Antelopinae species of the Bovidae, have not as yet been clarified. In this study, several sialyl oligosaccharides were purified from a sample of addax colostrum and characterized as follows: Neu5Ac(α2-8)Neu5Ac(α2-3)Gal(β1-4)Glc, Neu5Gc(α2-8)Neu5Gc(α2-3)Gal(β1-4)Glc, Neu5Ac(α2-3)Gal(β1-4)Glc, Neu5Ac(α2-6)Gal(β1-4)GlcNAc, Neu5Gc(α2-3)Gal(β1-4)Glc, Neu5Gc(α2-6)Gal(β1-4)Glc, Neu5Gc(α2-6)Gal(β1-4)GlcNAc.

Highly pathogenic avian influenza virus among wild birds in Mongolia.

Mongolia combines a near absence of domestic poultry, with an abundance of migratory waterbirds, to create an ideal location to study the epidemiology of highly pathogenic avian influenza virus (HPAIV) in a purely wild bird system. Here we present the findings of active and passive surveillance for HPAIV subtype H5N1 in Mongolia from 2005-2011, together with the results of five outbreak investigations. In total eight HPAIV outbreaks were confirmed in Mongolia during this period.

Cloning, monoclonal antibody production, and bodily distribution pattern of a bovine lipocalin.

A bovine lipocalin, previously identified as a putative odorant-binding protein in bovine colostrum (bcOBP), was cloned and expressed, and its monoclonal antibody was established. bcOBP was constantly secreted into milk on day of parturition until at least 10 d postpartum at a concentration of 181±39 µg/L. Besides milk, bcOBP occurred in the nasal mucus, saliva, amniotic fluid, vaginal discharge, and blood plasma.
