          Abstract

          Hematological results are reported for 13 giant anteaters (Myrmecophaga tridactyla) and 13 collared anteaters (Tamandua tetradactyla). Animals were captive-reared adults held at the Fundação Parque Zoológico de São Paulo (São Paulo, SP, Brazil) and Parque Zoológico Municipal Quinzinho de Barros (Sorocaba, SP, Brazil), and were considered healthy on physical examination. Examined parameters included red blood cell count, white blood cell count, hematocrit, hemoglobin concentration, mean corpuscular volume, mean corpuscular hemoglobin, mean corpuscular hemoglobin concentration, total plasmatic protein and differential leukocyte counts. Also, a survey for hemoparasites was done and none was observed in thin blood smears. The results were generally similar to those previously reported in the exiguous literature for these species, providing further reference data for the interpretation of laboratory results besides health monitoring, assisting early disease diagnosis and providing relevant information for conservation programs for these species.

          Obteve-se os valores hematológicos de 13 tamanduás-bandeira (Myrmecophaga tridactyla) e 13 tamanduás-mirim (Tamandua tetradactyla) adultos e saudáveis segundo exame físico, oriundos de cativeiro, da Fundação Parque Zoológico de São Paulo (São Paulo) e do Parque Zoológico Municipal Quinzinho de Barros (Sorocaba). Os parâmetros hematológicos estudados incluíram contagem total de eritrócitos e leucócitos, hematócrito, concentração de hemoglobina, volume corpuscular médio, hemoglobina corpuscular média, concentração de hemoglobina corpuscular média, proteína plasmática total estimada e contagem diferencial de leucócitos. Também se realizou a pesquisa de hemoparasitas, não se encontrando nenhum nos esfregaços sanguíneos. De maneira geral, os valores obtidos não diferiram muito daqueles presentes na pouca literatura existente, contribuindo com dados adicionais para a interpretação de resultados laboratoriais, visando acompanhamento do estado sanitário, auxílio no diagnóstico de enfermidades e programas de conservação dessas espécies.

            A survey of hemoparasite infections in free-ranging mammals and reptiles in French Guiana.

            Blood smears of 1,353 free-ranging mammals (35 species) and 112 reptiles (31 species) from French Guiana were examined for hemoparasites. Parasites from 3 major groups were recorded: Apicomplexa (including hemogregarines, piroplasms, and Plasmodium spp.), Trypanosomatidae, and Filaroidea. Fifty percent of the individuals (86% of the species) were infected by parasites from at least 1 group. Hemogregarines, identified as Hepatozoon sp., infected numerous snakes with high prevalences (30-100%); infection is reported for the first time in 5 host genera of snakes: Clelia, Oxybelis, Pseustes, Rhinobotryum, and Bothriopsis. Infections were also observed in 4 marsupial species and 1 rodent. Hepatozoon spp. recorded in Didelphis albiventris (Marsupialia) and Coendou prehensilis (Rodentia) may be new species. Plasmodium sp. were observed in 2 snake species, Dipsas indica (Colubridae) and Bothrops atrox (Viperidae). Plasmodium brasilianum was recorded in all 5 primate species examined. Piroplasms were observed in all mammal orders except primates. Large terrestrial rodents were the main hosts of members of the Babesidae; 42% of Myoprocta acouchy, 36% of Dasyprocta agouti, and 44% of Agouti paca were infected. Trypanosomes were common in mammals and were recorded in 70% of the examined genera. Trypanosoma cruzi-like infections were reported in 21 mammal species, including sloths, rodents, carnivores, and primates. Microfilariae were also widespread, with higher prevalences in sloths, anteaters, and porcupines (>40% of the individuals infected) and in tamarins (95% infected). This survey highlights some potential anthropozoonotic risks due to the recent further evidence of Plasmodium brasilianum and P. malariae as a single species and to the increased diversity of hosts for Trypanosoma cruzi.
