Bluetongue virus serotypes 1, 3, 6, and 12 were isolated from sentinel animals. To the authors' knowledge, these are the first isolations of BTV from the region studied and the first isolations of these serotypes in the Western Hemisphere. Clinical disease attributable to BTV infection was not observed in sentinel animals. The incidence pattern, with respect to age and geographic location, was determined. The need to evaluate the epizootiologic features or arthropod-borne viruses (arboviruses) on a regional ecologic basis is stressed.

Viraemia persisted for two months in some lambs even though they received colostrum. It is suggested that transplacental infection of bluetongue virus in sheep may be an overwintering mechanism for the virus in some areas of the world.

A mixed viral infection of PPR virus (morbillivirus) and adenovirus was confirmed in both goats. The adenoviruses did not conform to any of the ovine and bovine serotypes recognised; the two isolates were considered different serotypes. It is concluded that, although the role of adenoviruses in the epizootiology of PPR in Nigeria is difficult to appraise, they are probably commensals. This is believed to be the first report of the isolation of adenoviruses from goats.

Since veterinary education in most countries is now focused on preparing clinicians rather than public health practitioners or research scientists, educators should recognise the importance of research by emphasising the principles and key methodologies that are generic in the life sciences. This exposure will provide a baseline understanding for all students, may encourage some to complete research projects and research-focused externships during school, and will ultimately inspire others to pursue research training after graduation. All aspects of veterinary research would benefit from this approach, including veterinary public health. This paper discusses the essential understanding of research that should be gained through veterinary education, particularly within the evolving nature of veterinary public healt...

The most prominent issues putting pressure on global health today include the dramatic emergence and spread of zoonotic diseases, contamination of food, water and soil, bioterrorist events, and degradation of resources and habitats. Current global health challenges have prompted a call for more holistic, collaborative, action-oriented approaches toward the goal of logical and practical solutions. Veterinarians have pivotal obligations, opportunities, and contributions to make in enhancing public health, recognising and responding to zoonotic disease transmission, maintaining food and water quality, and promoting wildlife and ecosystem health.

Large feral populations in North America and Australia are principally derived from introduced domestic pigs. In Europe, most wild boar are found in Germany and Poland. While wild swine are certainly a significant reservoir of infection for domestic swine diseases (for example, African swine fever virus in wild boar in Sardinia), these swine generally do not constitute a major public health risk. Brucella suis infections and trichinellosis are the most important zoonotic threats to public health.

All exposed pigs became sick and died or were killed after becoming moribund. Necropsy revealed lesions typical of African swine fever, but several pigs had marked hemorrhage surrounding the kidneys or rectum or in the gastric, hepatic, or ventral abdominal region that, in the field, might have suggested trauma or poisoning as a cause of death. Most pigs had severe lesions associated with kidney worms. Virus was detected in the blood and selected tissues of each pig, using the hemadsorption reaction in porcine monocyte cultures; direct or indirect immunofluorescence was used to confirm the diagnosis.
