“…Blood taken from toe clips was used to make smears that were fixed in methanol and stained with Giemsa. Only one of us (JJS) viewed the slides under 900X to determine if the animal was infected with Plasmodium mexicanum, or two other blood parasites, Schellackia occidentalis (another protozoan), or a piroplasm (probably a virus) (Schall 1983;Telford 1984). Animals infected with parasites other than Plasmodium were not used in the trials.…”

Summary. The effect of malarial parasitism on the ability of male western fence lizards, Sceloporus occidentalis, to compete for access to females was assessed experimentally. Pairs of male lizards, one infected with the malarial parasite, Plasmodium mexicanum, and the other not infected, were matched by size and color and placed in large seminatural outdoor enclosures along with an adult female lizard. Infected males displayed to females and to other males less often than did noninfected male lizards. Noninfected lizards were dominant in social interactions more often than malarious animals, based on duration and intensity of agonistic encounters toward the other male, and time spent with the female. Thus, malarial infection hinders the ability of male fence lizards to compete for mates.

“…Muitos invertebrados foram descritos como vetores e hospedeiros deϐinitivos, incluindo os carrapatos, mosquitos, moscas, piolhos, pulgas e sanguessugas (Clark et al 1973, Göbel & Krampitz 1982, Telford Jr 1984.…”

Determinação de hemogregarina em Boa constrictor constrictor mantidos em cativeiro

et al. 2012

O presente estudo teve como objetivo determinar a presença de hemogregarina em boídeos mantidos em cativeiro no Estado do Pará, bem como, relacionar a hemoparasitose com pre-disposição sexual, alterações clínicas e hematológicas e a presença de ectoparasitos. Esta pesquisa teve autorização do Sistema de Autorização e Informação em Biodiversidade do Instituto Brasileiro do Meio Ambiente e dos Recursos Naturais Renováveis para ser realizado. Utilizaram-se 19 serpentes da família Boidae mantidas em cativeiro, pertencentes ao "Museu Paraense Emilio Goeldi" (Belém/PA) e "Sítio Xerimbabo" (Santo Antônio do Tauá/PA). A pesquisa de hemogregarina foi realizada em esfregaços sanguíneos examinados no aumento de 400x, enquanto que a parasitemia foi determinada contando- se 550 hemácias em aumento de 1000x. Do total de animais estudados (n=19), nove encontraram-se parasitados (47,36%), não havendo correlação entre presença de hemogregarina, pré-disposição sexual, alterações clínicas e hematológicas nas serpentes hospedeiras. A correlação da hemoparasitose foi detectada apenas quanto à presença de ectoparasitas nas serpentes, no entanto, estudos adicionais são necessários para verificar a prevalência de hemogregarinas em animais mantidos em cativeiro no Estado do Pará, visto que, existe grande lacuna de dados na literatura veterinária especializada no que diz respeito à fauna da região amazônica.

“…It was given the name of Haemogregarina amphisbaenae Pessôa, 1968, but most probably does not belong to this genus. Telford (1984) mentions the finding of what was probably the same parasite in a single specimen of A. alba from Venezuela, but gave no description. I have examined thin blood films from 43 of these lizards, from various localities in Pará, North Brazil, without encountering this haemogregarine (unpublished observations).…”
