ABSTRACT
Descreveram-se os valores hematológicos de bugios pretos (Alouatta caraya) e estabeleceram-se diferenças entre sexo e idade, de 36 animais aparentemente saudáveis, de vida livre da região do Alto Rio Paraná, sul do Brasil. Os animais foram capturados e contidos quimicamente com cloridrato de tiletamina e cloridrato de zolazepam, na dose média de 5,5mg/kg, por via intramuscular. Na comparação entre os sexos, houve diferença para número de hemácias (4,48±1,36 e 3,58±0,91 x10(6)/mm³), maior nas fêmeas, e volume globular médio (90,99±27,65 e 118,36±44,63fL) e número de eosinófilos (0,30±0,24 e 0,76±0,85 x10³/mm³), maior nos machos. O volume globular (39,46±3,53 e 36,69±3,54 por cento) e a proteína total plasmática (7,91±0,53 e 7,40±0,63g/dL) foram significativamente mais baixos nos animais jovens.
The hematologic values and the influence of gender and age were described in 36 free-ranging healthy black-and-gold howler monkeys (Alouatta caraya) from the region of Paraná river, Southern Brazil. The animals were caught with trap models and intramuscularly anesthetized with 5.5mg/kg tilitamine/zolazepam hydrochlorides. The red blood cells were higher in females (4.48±1,36 vs. 3.58±0.91x10(6)/mm³) while mean corpuscular volume (90.99±27.65 and 118.36±44.63 fL) and eosinophils (0.30±0.24 and 0.76±0.85x10³/mm³) were significant higher in males. The packed cell volume (39.46±3.53 and 36.69±3.54 percent) and plasma total protein (7.91±0.53 and 7.40±0.63g/dL) were lower in juveniles.

The aim of this study was to evaluate the seroprevalence of Paracoccidioides brasiliensis infection in wild New World monkeys (Cebus sp. and Alouatta caraya). A total of 93 animals (Cebus sp., n = 68 and Alouatta caraya, n = 25) were captured in the Paraná River basin, Paraná State, Brazil and the serum samples were analyzed by ELISA and immunodiffusion using P. brasiliensis gp43 and exoantigen as antigens, respectively. The seropositivity observed by ELISA was 44.1% and 60% for Cebus sp. and A. caraya, respectively, while by immunodiffusion test Cebus sp. showed positivity of 2.9% only. No significant difference was observed in relation to age and sex. This is the first report of paracoccidioidomycosis in wild capuchin monkeys and in wild-black and golden-howler monkeys. The high positivity to P. brasiliensis infection in both species evaluated in our study and the positivity by immunodiffusion test in Cebus sp. suggest that natural disease may be occurring in wild monkeys living in paracoccidioidomycosis endemic areas.
