“…Oxyurida are very rarely noted in snakes, and are more common in lizards and especially tortoises (Buńkowska et al, 2011). The list of nematodes recorded in South African snakes does not contain single information about Oxyurida (Hering-Hagenbeck & Boomker, 2000); there are no records of these parasites from Costa Rica (Bursey et al, 2011). Eggs identified as pinworm eggs were found in the faeces of one brown house snake L. fuliginosus from a warehouse.…”

Endoparasites of exotic snakes (Ophidia)

2014

31 SummaryExotic reptiles, among them snakes, are a novelty in the world of pets. A total of 28 snakes housed in the City Zoological Garden in Wrocław and 23 snakes from zoological wholesale were examined for the presence of endoparasites. Both parasitological sections of dead reptiles and coprological examination were done. Endoparasites were detected in a total of 13.7 % of snakes, including 21.7 % of those coming from the zoological wholesale and 7.1 % of the zoo-kept snakes. Two groups of protozoa were detected: Choleoeimeria sp. and Ciliata, as well as nematodes: Kalicephalus sp., Dioctowittidae and a pinworm (Oxyurida). The zoo snakes were also found to carry pseudoparasites.

“…It seems that H. onchocercum rarely parasitizes rattlesnakes, since it has only been documented in Crotalus durissus (Vicente et al 1993), a species closely related to C. tzabcan, and its geographic range includes Brazil, Costa Rica, Panama and Trinidad (Desportes 1941;Caballero 1947;Everard 1975;Bursey and Brooks 2011). Therefore, the specimens of H. onchocercum found in this study represent the first record of the genus in Mexico.…”

“…Hexametra boddaertii had not been previously reported in the Yucatán Peninsula, maybe because there have been few studies of snake parasites in the region (e.g., González-Solís and Terán-Juárez 2013; González-Solís et al 2014). Travassosascaris araujoi has been documented in C. durissus, C. pyrrhus and C. simus (Sprent 1978;Bursey and Brooks 2011;Goldberg et al 2013). Sprent (1978) suggested that T. araujoi appears to be restricted to rattlesnakes in Central and South America, but it also occurs in rattlesnakes from North America, and has been documented in colubrid and dipsadid snakes (Bursey and Brooks 2011;Goldberg et al 2013).…”

“…Additionally, none of the specimens examined appeared to be affected by the presence of the parasites. Such parasites have been able to colonize several rattlesnake species, including those in the Crotalus durissus group (to which C. tzabcan belongs), like Capillaria crotali (Rudolphi, 1819), H. onchocercum, H. boddaertii, K. inermis, Ophidascaris ardnti Sprehn, 1929, P. crotali and T. araujoi (Peláez and Julia 1983;Goldberg and Bursey 1999;Goldberg et al 2006;Pinto et al 2010;Bursey and Brooks 2011).…”

The helminth and pentastomid fauna of 50 specimens of from the Yucatán Peninsula, Mexico is documented. The examination revealed the presence of three nematode species (, , and), and one pentastomid (). The threee nematode species had the same prevalence (2%), while the pentastomid had a higher prevalence (8%). The pentastomid was the most abundant and intense parasite, although it was only found in four snake hosts. acts as definitive host for the adult helminths and pentastomids, with rodents as the probable intermediate hosts. This work represents the first systematic survey on the parasitic helminth and pentastomid fauna of , and includes four new geographical records. Additionally, a checklist of helminths and pentastomids reported for and is provided. To date, a total of 32 helminth and 7 pentastomid species have been recorded as parasites of rattlesnakes. Nematoda possessed the highest species richness. The genera with the highest number of host species were and , followed by. The rattlesnake species with the highest number of reported parasites was (18 nematodes and 2 pentastomids).

“…boddaertii was originally isolated and described by Baird (1860), who removed a single female specimen from a Boddaert's tropical racer (Mastigodryas boddaerti), a colubrid snake found throughout much of South America. Since then, several neotropical colubrid snakes have been identified as host for this parasite including: Oxyrhopus trigeminus and Philodryas patagoniensis from Brazil (Sprent, 1978), Spilotes pullatus and Trimorphodon biscutatus from Costa Rica (Bursey and Brooks, 2011), and a Philodryas baroni specimen from an unknown locality (Hartdegen and Gamble, 2002). The current study reports the presence of H. boddaertii in an individual O. guibei captured in Argentina, which not only identifies a new host for this parasite, but also reports the first country record for H. boddaertii.…”

The current study summarizes the postmortem examination of a specimen of Oxyrhopus guibei (Serpentes, Colubridae) collected in Iguazu National Park (Argentina), and found deceased a week following arrival to the serpentarium of the National Institute of Tropical Medicine (Argentina). Although the snake appeared to be in good health, a necropsy performed following its death identified the presence of a large number of roundworms in the coelomic cavity, with indications of peritonitis and serosal adherence. Additional observations from the necropsy revealed small calcifications in the mesothelium of the coelomic cavity; solid and expressive content in the gallbladder; massive gastrointestinal obstruction due to nematodes; and lung edema and congestion. Histopathological analyses of lung sections also showed proliferative heterophilic and histiocytic pneumonia. Parasites isolated from both the intestine and coelomic cavity were identified as Hexametra boddaertii by a combination of light and scanning electron microscopic examination. Results from this necropsy identify O. guibei as a new host for H. boddaertii, and is the first report of a natural infection by Hexametra in Argentina. Since Hexametra parasites may contribute to several pathological conditions in humans, and with the recent availability of O. guibei specimens through the illegal pet trade, it is necessary to consider the possibility of zoonotic helminth transmission of Hexametra from snake to human.
