ABSTRACT
Abstract The role of rodents as reservoirs of helminths of public health importance is not well known. The zoonotic potential of Syphacia spp. has been confirmed; therefore, the study aimed to estimate the occurrence of oxyurid nematodes in small rodents from pet shops and breeding clubs in Slovakia. Fecal samples of 586 pet rodents kept in 133 cages were collected between 2016 and 2018 and examined by Faust´s flotation method. Four species of oxyurid nematodes, Syphacia muris, S. obvelata, Aspiculuris tetraptera and Paraspidodera uncinata were detected. A. tetraptera was found in the faecal samples of all rodent species included in this survey. The number of positive boxes varied from 5.4% in hamsters to 70.0% with mice. The prevalence of Syphacia muris was highest in Mongolian gerbils where up to 75.0% boxes were positive; S. obvelata was found in 26.7% of boxes with mice, 25.0% of boxes with Mongolian gerbils and 3.2% of boxes with rats. The high prevalence of Syphacia spp. in all animal species points out the infection risk for humans. Animals offered for sale are often in close contact with human beings; therefore they should be regularly tested for parasites and then effectively dewormed.
Resumo O papel dos roedores como reservatórios de helmintos de importância para a saúde pública não é bem conhecido. O potencial zoonótico de Syphacia spp. foi confirmado; portanto, o estudo teve como objetivo estimar a ocorrência de nematóides oxiurídeos em pequenos roedores de pet shops e clubes de reprodução na Eslováquia. Amostras fecais de 586 roedores mantidos em 133 gaiolas foram coletadas entre 2016 e 2018 e examinadas pelo método de flotação de Faust. Foram detectadas quatro espécies de nematódeos oxiurídeos, Syphacia muris, S. obvelata, Aspiculuris tetraptera e Paraspidodera uncinata, A. tetraptera foi encontrado nas amostras fecais de todas as espécies de roedores incluídas nesta pesquisa. O número de gaiolas positivas variou de 5,4% em hamsters a 70,0% em camundongos. A prevalência de Syphacia muris foi maior nos gerbilos da Mongólia, onde até 75,0% das gaiolas foram positivas; S. obvelata foi encontrada em 26,7% das gaiolas com camundongos, 25,0% das gaiolas com gerbilos da Mongólia e 3,2% das gaiolas com ratos. A alta prevalência de Syphacia spp. em todas as espécies animais aponta o risco de infecção para os seres humanos. Animais oferecidos para venda estão frequentemente em contato próximo com seres humanos; portanto, eles devem ser regularmente testados quanto a parasitas e, então, efetivamente desparasitados.

We present the results of paleoparasitological analyses in coprolites of Kerodon rupestris, rodent endemic to rocky areas of Brazil's semiarid region. The coprolites were collected from excavations at the archaeological site of Toca dos Coqueiros, in the National Park of Serra da Capivara, southeastern of state of Piauí. Syphacia sp. (Nematoda: Oxyuridae) eggs were identified in coprolites dated at 5,300 ± 50 years before present. This is the first record of the genus Syphacia in rodent coprolites in the Americas.

The house mouse, Mus musculus, has been present in Chile since approximately 1600 AD and it is the most tipically synanthropic rodent in Chile. In order to know its parasites a survey was conducted in three different localities in Santiago. The helminthes community was poor in species and only three nematodes species were found: Syphacia obvelata,Aspiculuris tetraptera and Physaloptera calnuensl All these species constitutes the first record in Chile. This is also the first record of P. calnuensis in this host. Syphacia obvelata was the most abundant and the most prevalent.
El ratón doméstico, Mus musculus, está en Chile desde aproximadamente el 1600 DC. y es el más sinantrópico de los roedores chilenos. Para conocer sus parásitos se realizó un estudio en tres diferentes localidades de Santiago. La comunidad de helmintos fue pobre en especies y sólo se encontraron tres especies de helmintos: Syphacia obvelata, Aspiculuris tetraptera y Physaloptera calnuensis; todas estas especies constituyen el primer registro para Chile. Esté es también el primer hallazgo de P. calnuensis en este hospedador. Syphacia obvelata fue la especie más prevalente y abundante.

Se analizaron los parásitos de 40 liebres (Lepus europeaus) (20 de la Provincia de Ñuble y 20 de Última Esperanza) capturadas entre enero de 2003 y agosto de 2004. En la Provincia de Ñuble se aislaron tres especies de endoparásitos: Trichostrongylus retortaeformis (60 por ciento), Passa-lurus ambiguus (5 por ciento) y Eimeria spp. (45 por ciento). En Última Esperanza se encontró sólo la especie T. retortaeformis (60 por ciento). Se aisló además una especie de ectoparásito correspondiente al Phthiraptera Haemodipsus lyriocephalus en una liebre de la Provincia de Ñuble. No se estableció ninguna relación significativa entre la presencia de los parásitos gastrointestinales con el sexo y edad de las liebres. Tampoco hubo una diferencia significativa entre el parasitismo provocado por T. retortaeformis en las dos zonas estudiadas.
The parasites of 40 Lepus europaeus (hares) were analyzed (20 of the Ñuble Province and 20 of Ultima Esperanza) caught between January 2003 and August 2004. In the Ñuble province three endoparasites species were isolated: Trichostrongylus retortaeformis (60%), Passalurus ambiguus (5%) and Eimeria spp. (45%). In Ultima Esperanza only T. retortaeformis was isolated with 60% of infection. The ectoparasite species isolated corresponded to the Phthiraptera Haemodipsus lyriocephalus in a hare of the Ñuble Province. No significant differences in the presence of gastrointestinal parasites were found with respect to sex and age of the hare. Nor was there any significant difference between parasitism of T. retortaeformis in the two studied zones.
