Description of a new ascaridoid parasite of Bothrops jararaca Wied (Reptilia, Ophidia) in Brazil

Abstract

A new species of Ophidascaris Baylis, 1920 is described on the basis of specimens recovered from the pit viper Bothrops jararaca Wied, 1824 in Brazil. The new species referred here was compared to other of the genus that are the closest. The differentiation was based on reliable morphological characters, mainly on what refers to the spicular length, number and distribution of caudal papillae, location of the vulvar opening, eggs size and aspect of the labial indentations. Moreover, female specimens are the only to possess a most prominent and characteristic post-anal tubercle-like structure and when analyzed together with the males, that show a great number of pre-cloacal papillae, the presence of an unpaired papilla and also of a less conspicuous post-cloacal tubercle-like structure, permit the prompt identification of the new species.

Parasitismo em serpentes

“…A migração larvar pode ocasionar lesões inflamatórias, ulcerativas e purulentas em pulmão, traqueia e outros sítios. Infecções secundárias podem agravar o quadro (Klingenberg, 1993;Araújo et al, 1999 (Siqueira et al, 2005). Silva e colaboradores (2001) em estudo envolvendo Crotalus durissus em sistema semiextensivo encontrou O. sprenti no estômago de 16,7% dos animais.…”

Ophidascaris wangi sp. n. and O. najae (Gedoelst, 1916) (Ascaridida: Ascaridoidea) from snakes in China

“…O. durissus Panizzutti, dos Santos, Vicente, Muniz-Pereira et Pinto, 2003 (Panizzutti et al 2003, Siqueira et al 2005. However, according to the description of O. durissus given by Panizzutti et al (2003), this species cannot be regarded as belonging to Ophidascaris because of the absence of interlabia and appears more likely to be a species of Hexametra Travassos, 1920.…”

“…However, according to the description of O. durissus given by Panizzutti et al (2003), this species cannot be regarded as belonging to Ophidascaris because of the absence of interlabia and appears more likely to be a species of Hexametra Travassos, 1920. Siqueira et al (2005) described O. tuberculatum, which should belong to the 'arndti' group of Sprent (1988), but, unfortunately, these authors did not mention the work of Sprent (1988) Ophidascaris najae (Gedoelst, 1916) Figs. 4-6…”

Prevalencia endoparasitaria de serpientes Bothrops asper (Garman, 1884) y Bothrops atrox (Linnaeus, 1758) en condiciones de cautividad en el Ecuador

“…Es conocido en los reptiles que el estrés de la cautividad puede conducir a enfermedades graves (Mihalca, 2010;Santos et al, 2008;QuesadaMorúa, 2005;Modrý et al, 2001), y en estudios provenientes de serpientes en cautiverio, el endoparasitismo ha sido una de las enfermedades mayormente reportadas (Pinto et al, 2010;Junker et al, 2009;Seghetti y Traversa, 2007) encontrándose entre estos hallazgos: nemátodos (Silva et al, 2007;Siqueira et al, 2005), céstodos (Gómez-Puerta, 2011;Sánchez et al, 2004), pentastómidos (Ayinmode et al, 2010;Gárate et al, 2007), protozoos (Matsubara et al, 2002), entre otros.…”
