RESUMEN
Idiopathic epilepsy was diagnosed in 3 gaur in a zoologic park collection during a 3-year period. Seizures were characterized by tonic rigidity of all limbs. Results of serum biochemical analysis, CBC, blood lead analysis, CSF analysis, and necropsy were within normal limits in all gaur. The role of heredity in development of seizures in these gaur is unclear because of limited founder stock of gaur in North America.

Administration of 200 micrograms mestranol/day (oestrogen) to ovariectomized chimpanzees caused a rapid decrease of circulating gonadotrophin concentrations to values similar to those in intact females. Administration of 2 mg chlormadinone acetate (progestagen) resulted in a prompt and significant rise in LH and FSH. This rise was accompanied by alteration in the physical characteristics and electrolyte composition of the cervical mucus which were the same as those observed around the time of ovulation. These results suggest a role of preovulatory progesterone secretion in relation to changes associated with ovulation in the chimpanzee.

Callitrichid hepatitis (CH) is a highly fatal, emerging arenavirus disease of captive South American marmosets and tamarins (Callitrichidae), including the endangered golden lion tamarin. A common-source outbreak of CH in golden lion tamarins and pygmy marmosets at a US zoo resulted from a single feeding of the primates with newborn mice in apparently infected with lymphocytic choriomeningitis virus (LCMV). Isolates from livers of mice and primates were related to isolates from previous CH outbreaks and to laboratory strains of LCMV by serology and nucleic acid hybridization, and 2 surviving animals developed antibody to other LCMVCH isolates and to laboratory strains of LCMV. Thus, LCMV, an arenavirus prevalent in wild mice in the US, can cause sporadic fatal hepatic disease in primates. Exposure of humans to wild or laboratory mice or to marmosets and tamarins that are infected with wild-type strains of LCMV poses the danger of serious disease.

A cytopathogenic virus with size and structural characteristics of a Herpesviridae was isolated from a cheetah with severe ulcerative dermatitis. Restriction endonuclease analysis and cross-hybridization studies revealed that the isolate was related to feline herpesvirus type 1 (FHV-1). Antigenic comparison studies using anti-FHV-1 serum demonstrated the presence of common antigens in the FHV-1 and the isolate from the cheetah.
