Rattus spp. are often found living together in the human environment. Till date, there are no data on nematodes in rats from Simeulue Island. Therefore, a research on the nematodes of Rattus spp. from Simeulue Island, Aceh was conducted to know the species and the pattern of nematodes infection. The observation was carried out by dissecting 14 carcasses of Rattus spp. and then observing the internal organs for nematodes. For the result, we identified four species i.e., Syphacia muris, Cyclodontostomum purvisi, Gongylonema neoplasticum, and Nippostrongylus brasiliensis with prevalence 28.5%, 7.1%, 7.1%, 85.7%, respectively, and parasite indexes 1-23, 1, 1, 2-118 individual parasites in each host, respectively.Key words: nematodes, parasites, Rattus spp., Simeuleu Island.

Summary The aim of this study was to determine the prevalence and species composition of helminths in commensal rodents captured inside private residences in the city of Villahermosa in Tabasco, Mexico. Trapping was performed at each house for three consecutive nights from October to December 2015. Fifty commensal rodents were captured: 23 Rattus norvegicus, 16 Mus musculus and 11 Rattus rattus. Rodents were transported alive to the laboratory and held in cages until they defecated. Feces were analyzed for helminth eggs using the Sheather’s flotation technique. The overall prevalence of helminths in rodents was 60 %: R. norvegicus was more likely to be parasitized (87.0 %) than R. rattus (63.6 %) and M. musculus (18.8 %). Eggs from at least 13 species of helminths were identified: Hymenolepis diminuta, Rodentolepis nana, Moniliformis moniliformis, Heligmosomoides polygyrus, Heterakis spumosa, Mastophorus muris, Nippostrongylus brasiliensis, Strongyloides ratti, Syphacia obvelata, Syphacia muris, Toxocara sp., Trichosomoides crassicauda, and Trichuris muris. This is the first study to report the presence of H. polygyrus, S. ratti and T. crassicauda in commensal rodents in Mexico. In conclusion, our results suggest that helminths commonly infect commensal rodents in Villahermosa and therefore rodents present a health risk to inhabitants in this region.

AbstractThe aims of this research were: 1) to determine the helminth parasite fauna of seventy two Rattus norvegicus (Berkenhout, 1769) individuals inhabiting poultry farms in the Pampean region of Argentina; 2) to examine the relationship between parasitism and individual characteristics of the hosts, and 3) to analyze the associations among helminths. The study was carried out in twenty-four poultry farms from autumn 2000 to winter 2001. Nematodes were found in the intestine or caecum rectum of the 74 % of rats and cestodes were found along all the intestine of the 28 % of rats. Heterakis spumosa (Travassos 1914) was a central species, whereas Syphacia muris, Yamaguti 1941, Nippostrongylus brasiliensis (Travassos 1914) and Hymenolepis diminuta (Rudolphi 1819) were satellite species. Helminths do not affect rat survival and growth of rats. Rats parasitized with H. spumosa and H. diminuta were larger and older than non-parasitized rats. The intensity of infection with H. spumosa significantly increased with rat age. Rats parasitized with Nippostrongylus brasiliensis and Syphacia muris did not differ in size and age with respect to non-parasitized ones. The mean intensity of infections per host was 33.74, 74.28, higher than 200, and 3.10 for H. spumosa, S. muris, N. brasiliensis and H. diminuta, respectively. The mean intensity of infection with H. spumosa was higher in summer than in the other seasons, while the higher mean intensity of infection with N. brasiliensis and S. muris occurred in autumn. Infections with Heterakis spumosa and Syphacia muris, and with Syphacia muris and Nippostrongylus brasiliensis were independent; while Heterakis spumosa and Nippostrongylus brasiliensis were negatively associated.

Background: Present study was aimed to record diversity, prevalence and risk assessment of nematode parasites in Indian gerbil, Tatera indica, a wild rodent species found in crop fields. Methods: Total 180 Indian gerbils (T. indica) were live trapped from crop fields of Ludhiana, Punjab between April, 2019 to March, 2020 and examined for the diversity and prevalence of nematode parasites in liver and gastrointestinal tract. Result: Only 33 (18.33%) gerbils were found infected with four nematodes species i.e. Nippostrongylus brasiliensis (39.40%), Calodium hepaticum (21.21%), Trichuris muris (21.21%) and Syphacia muris (18.18%). Eggs of N. brasiliensis, T. muris and S. muris were found in faecal samples. Pale yellow lesions on surface of liver and subsequent histopathology of infected liver indicated the presence of C. hepaticum eggs entrapped in parenchyma. Host age (χ2 = 8.78, P = 0.03) and season (χ2 = 9.21, P = 0.01) significantly affected the prevalence of N. brassiliensis and C. hepaticum, respectively. Shannon-Weiner index and Species Evenness of nematode parasites were maximum in monsoon season (1.04 and 0.94, respectively). Based on results proper rodent pest management is advised by integrated control measures at village level to prevent spread of diseases caused by them.

AbstractThe aim of the present study was to calculate the prevalence and intensity of intestinal helminths in the house mouse (Mus musculus) and the black rat (Rattus rattus) trapped in rural households of Yucatan, Mexico. Sampling was conducted during the rainy season from October to December 2011 and the dry season from January to March 2012. A total of 154 M. musculus and 46 R. rattus were examined, with 84.2% of M. musculus being infected with helminths compared with a significantly lower prevalence of 52.2% in R. rattus (P< 0.01). Adult M. musculus were more likely to be infected with helminths (89%) than subadults (63%) (P< 0.01). Four helminth species were identified: Taenia taeniaeformis larvae, Nippostrongylus brasiliensis, Syphacia muris and Trichuris muris. Nippostrongylusbrasiliensis was present more frequently in M. musculus than in R. rattus (P< 0.01) and in adult mice compared to subadults (P< 0.01). Trichuris muris was present only in adult mice. This is the first report of N. brasiliensis, S. muris and T. muris in Yucatan, Mexico, as well as the first to report the presence of N. brasiliensis in M. musculus from Mexico. The helminth fauna of commensal rodents present in households appears to constitute a low potential health risk to local inhabitants; however, it would be advisable to conduct further studies to better understand the public health risk posed by these rodent intestinal helminths.

SummaryThe aim of this paper was to study the occurrence of helminths inMus musculusandRattus rattusfrom urban, suburban and rural settlements in Yucatán, Mexico; and to analyse the host factors (e.g. sex) related to helminths’ distribution. Helminths in a total of 279 rodents were surveyed by visual examination of the liver for metacestodes and faecal examination for helminth eggs using the formalin-ethyl acetate sedimentation technique. The cestodesHydatigera taeniaeformis(metacestodes detected in the liver) andHymenolepis diminuta,and the nematodesAspiculurissp.,Nippostrongylus brasiliensis,Syphacia muris,Syphacia obvelata, andTrichuris muriswere identified. InM. musculus, the prevalence of infection withT. murisandH. taeniaeformiswas higher in the rural village compared to those in the suburban neighbourhood. ForR. rattus, a higher prevalence of infection withH. diminutawas found in the urban site compared to that in the suburban site. This study reports the occurrence ofH. diminutaamong rodents living in close proximity to humans, representing a potential public health risk. In addition, this survey increases our understanding of dynamic transmission among intestinal helminths recorded in Yucatán, Mexico.

AbstractA helminthological survey was performed on 143 brown rats (Rattus norvegicus) from the city of Palermo (Italy). The overall prevalence of helminth infection was 98.60 %. The following parasites were found: Brachylaima sp. (prevalence 8.39 %) (Trematoda); Taenia taeniaeformis larvae (11.89 %), Rodentolepis nana (13.29 %), Hymenolepis diminuta (24.48 %) (Cestoda); Gongylonema sp., (4.90 %), Syphacia muris (8.39 %), Nippostrongylus brasiliensis (18.88 %), Eucoleus gastricus (30.07 %), Mastophorus muris (30.77 %), Capillaria hepatica (54.55 %), Heterakis spumosa (82.52 %) (Nematoda) and one acanthocephalan (0.70 %). The species found in males were also present in females, with the exception of the acanthocephalan. No significant differences were found between males and females in prevalence (P%) or mean infection intensity (MI). However, a significant correlation between both P% and MI, as well as host age, was observed in some helminth species. Hosts were infected by one to six helminth species (median = 3). This is the first report from Sicily of helminths in R. norvegicus.
