The Pantanal is an area of 140,000 km2 located in the centre of South America between 16 and 21 S and 55 and 58 W. Its fauna is very rich and diverse. There are 230 species of fishes, 658 species of birds, 80 species of mammals, 50 species of reptiles and 25 species of Tabanidae. Extensive cattle ranches, varying from 10,000 to 200,000 hectares, occupy most of this wetland. It is populated by 3,996,000 cattle, 4,966 buffaloes and 139,760 horses (Cadavid Garcia, 1986). The tradicional cattle-raising system is based on calf and yearling production and its marketing involves the animal transport to market-places, river ports or railway stations. The most common means of transportation is on foot, in lots averaging 906 animals and taking on average 11 days to cover 230 km (Cadavid Garcia, 1985). Generally 6 cowboys herd the animals and usually each man has one extra horse. Trypanosomosis due to T. evansi is the principal protozoal disease of horses and wildlife in the Pantanal causing several hundred deaths of horses and other species every year. Recently several outbreaks have caused a high mortality in horses, for example on one farm 50.5% of a herd of 95 horses died (Silva et al., 1995a) and on another 30 horses out of a herd of 40 died, both due to T. evansi infection (unpublished data). In horses, the clinical signs observed were anemia, edema of the legs and lower parts, fever, lethargy, loss of appetite, weakness, lacrimation, abortion and loss of condition. The diagnosis was made using the microhematocrit centrifuge test (Woo test). MenosThe Pantanal is an area of 140,000 km2 located in the centre of South America between 16 and 21 S and 55 and 58 W.
