Whenever animals from different backgrounds and sources, and frequently with an incomplete vaccination history, are placed into these shelters, top respiratory disease with serious cough and fever is a common occurrence. Digestive tract infections also develop in these shelters. Both URI and diarrhea cause severe illness and an high rate of loss of life in sheltered animals unacceptably.Most individuals have multiple activating KIRs, of which KIR2DS1 is the only one known to are likely involved in both NK-cell activation and tolerance, through its acknowledgement of HLA-C2 molecules. In HLA-C2 homozygous individuals , in whom high degrees of the ligand are expressed as a self-molecule, NK cells that specifically exhibit KIR2DS1 are hyporesponsive.11-13 These findings are in keeping with those of studies in transgenic mice, which have shown that the function of NK cells expressing activating receptors particular for self-ligands is diminished.
