RESUMO
A dairy goat operation in Minnesota experienced a sudden, markedly increased mortality among its neonatal goats. Approximately 60 of 130 kids (46%) died. The animals had diarrhea and dyspnea of 1-2 days duration before death. Necropsy of 4 goat kids revealed marked, acute, catarrhal enteritis and fibrinous pleuropneumonia. Mannheimia haemolytica was isolated from the lungs. Basophilic inclusion bodies filling the entire nucleus were present in enterocytes of the ileum of 3 goats. Adenoviral particles were detected in the feces by electron microscopy and adenovirus was subsequently isolated from the intestinal content together with a parvo-like virus (dependovirus). Morphology, physicochemical characteristics, and neutralization tests indicated that the adenovirus resembled ovine adenovirus-2 (OAdV-2). However, the PstI restriction endonuclease pattern produced by the goat adenovirus was distinct from that of OAdV-2. This is the first report of enteritis in goats with an adenovirus antigenically related to OAdV-2 and with a parvo-like dependovirus.

No vaccine is a substitute for good management and diligent biosecurity in an aquaculture facility. It is always important to ensure the best water quality possible, provide quality nutrition, avoid overcrowding of tanks and raceways, remove dead fish to prevent pathogen buildup and spread, and reduce or eliminate unnecessary stress on fish. Use of a preventive medicine vaccine program and improved management can help ensure good health in a fish population and reduce the industries' use of therapeutic agents.
