Helmintos y sifonápteros parásitos de cinco especies de roedores en localidades de la Cuenca Oriental, en el centro de México

The Oriental Basin is located in part of the states of Puebla, Tlaxcala and Veracruz, inside of the Trans-Mexican Volcanic Axis; so far, only two helminth species have been recorded (Caballerolecythus ibunami and Lamotheoxyuris ackerti) and three siphonapterans (Anomiopsyllus perotensis, Stenistomera alpina and Echidnophaga gallinacea). Two sampling visits to the area were carried out in June of 2007 and July of 2008, including five localities in the region; eight helminth and nine flea taxa were collected from Liomys irroratus, Dipodomys phillipsii, Peromyscus difficilis, P. maniculatus and Reithrodontomys megalotis. New hosts and localities records for seven helminths and one taxa for fleas were found.La Cuenca Oriental se ubica en los estados de Puebla, Tlaxcala y Veracruz, localizada en el Eje Volcánico Transmexicano; hasta la fecha, sólo se han registrado en la localidad dos especies de helmintos (Caballerolecythus ibunami y Lamotheoxyuris ackerti) y tres sifonápteros (Anomiopsyllus perotensis, Stenistomera alpina y Echidnophaga gallinacea). Para el presente trabajo se realizaron dosmuestreos, en junio de 2007 y julio de 2008, los cuales incluyeron cinco localidades de la región, colectándose ocho taxa de helmintos y nueve de pulgas, todos provenientes de Liomys irroratus, Dipodomys phillipsii, Peromyscus difficilis, P. maniculatus y Reithrodontomys megalotis. Se registran nuevos hospederos y localidades para México en siete taxa de helmintos y sólo uno para las pulgas

Zoonotic parasites in feline coprolites from a holocenic mortuary context from eastern Patagonia (Argentina)

Nowadays, wildlife is one of the most important sources of zoonoses, and it is a major concern for the public health. Nevertheless, little is known about the role of wildlife as a reservoir and source of infectious diseases in the past. South America presents a wide diversity of wildlife. In the south of the continent, Argentina shelters a large diversity of neotropical carnivores. Although the paleoparasitological studies on carnivores have been increasing in southern Argentina, most of the efforts have been focused in a handful of sites located in western Patagonia. In this paper, two coprolites of felid found in Cueva Galpón, an initial late Holocene mortuary site from northeast Patagonia (Argentina), were studied for paleoparasitological purposes. Samples were processed by rehydration, homogenization, filtered and processed by spontaneous sedimentation. The samples were assigned to Puma concolor (puma) or Panthera onca (jaguar). Microscopic observations revealed that both coprolites were positive for parasite remains. High parasite richness was observed. Six nematodes, one cestode and one coccidian morphotypes were reported. This is the first time that Gnathostoma sp. and Spirocerca sp. were recovered from holocenic times from Patagonia. This finding implies that some diseases such as taeniasis, spirocercosis, gnathostomosis, ascariasis and coccidiosis could be present in holocenic wildlife from Patagonia prior to the Spanish colonization and domestic animal introduction. The overall results suggest that felids could have played a role as reservoirs and source of some parasitic species, some of which are zoonotic. Therefore, this animal could have entailed a risk agent for human health in the site.Facultad de Ciencias Naturales y Muse
