The re-emergence of foot-and-mouth disease (FMD) in Botswana is reported. The disease outbreak occurred in the Matsiloje Extension Area of Francistown veterinary district situated in the northeastern part of the country in an Office International des épízooties (OIE) recognized FMD free zone without vaccination. The disease affected cattle only and did not spillover into sheep and goats resident in the same extension area, as demonstrated by lack of seroconversion to FMD when tested. The virus isolate associated with the outbreak was identified as FMD virus; Southern African Territories (SAT) type SAT-2. The disease outbreak is discussed in relation to FMD outbreaks that have occurred previously within and outside Botswana. 相似文献

The first severe case of caprine contagious ecthyma (parapox) in Tswana goats is described from Botswana. Affected animals were indigenous adult Tswana goats. The case involved a flock of 12 goats of which 4 (33.3%) were very severely affected but none died. The lesions were confined to the head and included swollen lips, swollen submandibular lymph nodes, gingivitis, glossitis, ulceration on lip and gum mucosae and scab formation on ulcerated areas. No lesions were found on other parts of the body. This case was clinically indistinguishable from bluetongue. 相似文献

A retrospective serological survey of African horse sickness (AHS) in Botswana covering a 10-year period (1995-2004) is reported. The survey involved horses showing clinical symptoms of the disease; the horses had not been vaccinated against AHS. Over the period surveyed, serological evidence suggestive of infection with AHS virus (AHSV) was found in 99 clinical cases out of which 41.4% (41/99) cases were found during the 1st half (1995-1999) and 58.6 % (58/99) cases were found in the 2nd half of the survey period (2000-2004). These serological findings are discussed in relation to AHSV serotypes isolated from diseased horses in Botswana before and during the period of this serological survey. 相似文献

Virological and serological investigations were carried out in cattle, sheep and goats raised in the northern part of Tanzania in order to explore the possibility of bovine viral diarrhoea (BVD) virus cycling within these animal species. Two noncytopathogenic BVD virus isolates (A4/5/Tan86 and A4/10/Tan86) were obtained from sera sampled from inapparently infected indigenous (zebu) cattle originating from Kiteto district in Arusha region. No BVD virus was isolated from any of the sheep or goat sera. Seroepidemiological investigations revealed widespread prevalence of neutralising antibodies to BVD virus not only in cattle but also in sheep and goats. The seropositive rates are discussed in relation to previous observations in Tanzania and other parts of the world and to the livestock husbandry practices in northern Tanzania. 相似文献
