Bovine herpesvirus 1 (BHV-1) establishes a latent infection in sensory ganglionic neurons of cattle. During a latent infection, a single latency-related (LR) transcript is expressed. This observation suggested that DNA sequences in the LR promoter are positively regulated by neural cell type factors. The regulation of the LR gene was examined in neural cells as well as nonneural cells in transient assays. A 258-bp XbaI-SphI fragment from the LR promoter cis activated the herpes simplex virus type 1 thymidine kinase promoter in rat pheochromocytoma (PC-12) cells and differentiated human (HCNIA) neurons. In contrast, cis activation was not …

Enterococci in the alimentary tract of animals are believed to be commensal bacteria.3 However, Enterococcus durans has been associated with diarrhea in foals, piglets, and puppies. The possibility that E. durans is associated with diarrhea in calves has not been established, although grampositive cocci adhered to villi, occasionally together with Cryptosporidia, have been seen histologically in the small intestine of diarrheic calves. This report describes the association of E. durans and diarrhea in 4 calves.

Small mammals were trapped for 2 years at 16 localities on the central-Argentine pampa. Six species (Akodon azarae, Calomys musculinus, C. laucha, Bolomys obscurus, Oligory-zomys flavescens and Mus musculus) accounted for >95% of captures. The major breeding season, as assessed by pregnancies, was September or October through April or May. Mild weather in late autumn and winter of the second season resulted in a relatively longer breeding season during the 2nd year of the study. Females of all six species comprised significantly 50% of captures during the height of the breeding season. For most species, there was …

Michigan Bovine Tuberculosis Bibliography and Database
A naturally occurring outbreak of Mycobacterium bovid infection in captive wild elk (wapiti) in Montana was confirmed by mycobacteriologic examination. Twenty-eight of 143 elk responded to M. bovis purified protein derivative (PPD) tuberculin injected intradermally in the cervical region (SCT). The results of comparative cervical tuberculin skin tests conducted within 9 days of SCT revealed greater responses to M. bovis PPD tuberculin than to M. avium PPD tuberculin in 23 of 28 elk responding. At necropsy, several grossly visible tuberculous lesions were observed in the parenchyma of the lung, thoracic lymph nodes, and submandibular lymph nodes. Microscopic examination of appropriately …
