Alves,G.B.B.; Pinho,F.A.; Silva,S.M.M.S.; Cruz,M.S.P.; Costa,F.A.L..
Fifteen symptomatic and seven asymptomatic dogs infected naturally with Leishmania chagasi were examined in order to identify the presence of parasites and changes in heart and lung. Histopathological, cytological, and immunohistochemical analyses were performed on samples of heart and lung tissues. An inflammatory reaction characterized by inflammatory mononuclear, perivascular and intermuscular infiltrates was observed in both symptomatic and asymptomatic animals on histopathological analysis of the heart. In the lung, there was thickening of the alveolar septa due to congestion, edema, inflammatory infiltrate, and fibroblast proliferation. A focal reaction was observed although a diffuse reaction was present in both groups. On cytological examination,...

Sampaio Júnior,A.; Batista,M.C.S.; Cruz,M.S.P.; Silva,R.A.B.; Bona Nascimento,C.; Werneck,G.L..
The prevalence of anti-lentiviruses antibodies of small ruminants was investigated in goat herds in the city of Teresina, PI, Brazil. A seroepidemiological survey was conducted involving 480 animals, apparently healthy, belonging to six rural properties. The diagnostic test was the agar gel immunodiffusion (AGID), using antigens produced from cellular cultures infected with caprine arthritis encephalitis virus (CAEV Cork). Prevalences by gender and age were estimated considering sampling fractions for each farm. A general prevalence of 4.2%, was observerved, being 4.2% for females and 3.6% for males. Prevalences were higher among older goats. Regarding the breed standard, 23.5% were of the Anglo Nubian, 5.9% of the Boer, 35.3% Anglo Nubian x Boer...
