Transferência do Hepatozoon tupinambis, parasita do lagarto Tupinambis teguixin, para a serpente cascavel (Crotalus durissus terrificus), por intermédio do mosquito Culex fatigans

Abstract

Os autores obtiveram a transferência do Hepatozoon tupinambis (Laveran e Salibeni, 1909) parasita do lagarto Teiidae, Tupinambis teguixin, L., para a serpente cascavel, Crotalus durissus terrificus (Laur.), alimentando-a com mosquitos experimentalmente infectados. o parasita mantém os seus caracteres morfológicos no animal receptor, nos limites do tempo observado (cerca de 100 dias). O ofídio receptor apresentou cistos esquizogônicos do fígado.<br>The authors achieved a transfer of the Hepatozoon tupinambis (Laveran and Salibeni, 1909), a parasite of the Sauria: Tupinambis teguixin, L., to a rattlesnake of the species Crotalus durissus terrificus, feeding the latter with experimentally infected mosquitoes. The parasite maintained its morphological characteristics in the recepting animal throughout the whole observation period (about 100 days). Schizogonic cysts were found in the liver of the rattlesnake

Description of gamontogonic and sporogonic stages of Hepatozoon spp. (Apicomplexa, Hepatozoidae) from Caudisoma durissa terrifica (Serpentes, Viperidae)

“…Although several authors have been successful in experimentally infecting mosquitoes (Pessoa et al 1974;Wozniak and Telford 1991;Sloboda et al 2007;Telford 2010), the results obtained in the present study suggest that mosquitoes are not the natural hosts of these protozoans of Fig. 2 Sporogonic development of Hepatozoon sp.…”

“…Mosquitoes have been used as experimental vectors for Hepatozoon spp. of snakes with success (Pessoa et al 1974;Sloboda et al 2007;Telford et al 2008Telford et al , 2010. Bashtar et al (1991) monitored the developmental stages of Hepatozoon melhorni sp.…”

Hepatozoon (Eucoccidiorida: Hepatozoidae) in wild mammals of the Americas: a systematic review

“…Furthermore, spillover of Hepatozoon spp. in atypical hosts may lead to infections more virulent than those observed in natural hosts [ 196 – 198 ].…”

Morphologic and morphometric analysis of Hepatozoon spp. (Apicomplexa, Hepatozoidae) of snakes

“…Besides, the gamonts of a same species of Hepatozoon can present slight morphologic changes depending on the host. Pessoa et al (1974) demonstrated that it was possible to transfer H. tupinambis of the lizard Tupinambis teguixin to the snake C. durissus terrificus. The transfer induced changes in the parasite so that in the lizard, Hepatozoon species produced eryth-…”
