RESUMO
There is some evidence that dogs can be naturally infected by Paracoccidioides brasiliensis in endemic areas of paracoccidioidomycosis. In order to evaluate canine infection with this fungus, a survey with 149 urban and 126 rural dogs was carried out using ELISA and intradermal tests with the gp43 antigen of P. brasiliensis in Uberaba, Minas Gerais state of Brazil. Forty-one out of 149 urban dogs were euthanatized and had their lungs, liver and spleen removed. One slice from each viscera was processed for histopathological examination and the remaining was homogenized and then cultivated on mycobiotic agar at room temperature and Fava-Netto medium at 35 degrees C and observed for 12 weeks. Of urban dogs, 75 (50.3%) were small adult females, 56 (36%) were strays, while 93 (64%) had been donated to the municipal zoonosis control center. Nine (6.2%) had a positive intradermal test without statistical differences regarding gender, race, nutritional status or origin. No colonies with microscopic or morphology appearances resembling P. brasiliensis were isolated, nor granulomatous process or fungal structures were observed from histopathological examination. Eighty (53.6%) of the urban dogs presented seroreactivity, without statistical differences regarding gender, race, nutritional state, origin, or positive intradermal test. Of 126 rural dogs, 102 (80.5%) presented antibodies against gp43 antigen, and this was statistically significant in relation to the reactivity detected in urban dogs (P = 0.0001). Thus, dogs are commonly infected with P. brasiliensis, but they probably present natural resistance to develop paracoccidioidomycosis.

Foi realizado inquérito para avaliar alguns aspectos epidemiológicos da teníase em 100.144 indivíduos do Programa Saúde da Família. Foram identificados 185 (0,2 por cento) indivíduos com antecedentes de teníase. Destes, 112 (60,5 por cento) receberam tratamento com praziquantel. Em 97 (86,6 por cento) dos casos, houve eliminacão de proglotes que corresponderam a Taenia saginata e Taenia solium em 36 (37,1 por cento) e 4 (4,1 por cento), respectivamente.

An epidemiologic survey was carried out on 110,144 people from the Health Family Program to evaluate some Epidemiologic aspects of teniasis. Previous history of passing proglottides was registered in 185 (0.2%) of them, and 112 (60.5%) received praziquantel. After this 97 (86.6%) passed proglottides characterized as Taenia Saginata and Taenia Solium in 36 (37.1%) and 4 (4.1%) respectively.
