“…Moreover, previous studies have shown that nematodes and cestodes are more abundant in helminth communities of R. norvegicus (Abu-Madi et al, 2001Hancke et al, 2011;Kataranovski et al, 2011). This result is consistent with our findings, as nematodes accounted for 98.7% of the helminth community.…”

Rattus norvegicus has attracted much attention because of its role as a reservoir of zoonotic pathogens. This work aimed to identify the intestinal helminth species in R. norvegicus and to analyse the effects of temperature, rainfall, host age and sex on the helminth community structure. Moreover, this study investigated the possible associations among helminth species in an urban population of R. norvegicus in São Gonçalo, Rio de Janeiro, sampled during the rainy and dry seasons over a span of 2 years. A total of 112 rats were infected by six species of helminths. The nematode Nippostrongylus brasiliensis was the most prevalent and abundant species, with high mean intensity in both seasons, followed by Strongyloides venezuelensis, Heterakis spumosa, Raillietina sp., Hymenolepis nana and Moniliformis moniliformis. Co-occurrence was found between N. brasiliensis and S. venezuelensis and between N. brasiliensis and H. spumosa. The occurrence of S. venezuelensis was related to rainfall. The understanding of the helminth community structure in this synanthropic rat provides basic information on parasites of public health importance, as two helminth species (H. nana and M. moniliformis) recovered from rats in the urban area studied can infect humans.

“…The success of murine rodents in anthropogenic habitats could be the reason for many parasitological studies done worldwide. In general, studies have focused primarily on list of all parasites species and analyzed biotic and abiotic factors influencing composition and parasite burden (see Battersby et al 2002;Milazzo et al 2010;Easterbrook et al 2007;Kataranovski et al 2008Kataranovski et al , 2011Hancke et al 2011). In recent decades, the detection of diseases associated with rodents as reservoirs has increased (see Meerburg et al 2009), which gives them a significant role in disease transmission to humans.…”

Richness and diversity of parasites depend on a set of interrelated factors related to the characteristics of the host, the environment and the parasites itself. In the City of Buenos Aires, rodent communities vary according to landscape structure. The goal of this paper was to study the variations of helminth richness and diversity among invasive rodent species in different landscape units of the City of Buenos Aires. 73% of the rodents were parasitized with at least one of the 10 identified helminth species. Each rodent species presented its own characteristics in terms of richness, diversity and helminth composition, keeping these characteristics still occupying more than one landscape unit. The infracommunities with greater diversity corresponded to R. norvegicus due to its high values of parasitic richness, proportion of infected hosts and parasite prevalence. Instead, R. rattus and M. musculus infracommunities had lower diversity since a high percentage of them presented a unique helminth species. Within the city, the inhabitants of shantytowns would be the most exposed to zoonotic diseases transmitted by rodents due to high abundance of rodents harboring a high parasite load, including species like Hymenolepis nana and H. diminuta, recognized worldwide from a zoonotic aspect.

“…Moreover, these rodent species are not only potential disease reservoirs since in these shantytowns they are actually carrying several pathogens that produce diseases to humans, such as Leptospira spp. (Seijo et al 2002), hantavirus Seoul (Cueto et al 2008), and human helminth parasites (Hancke et al 2011). This scenario, in association with other socio-environmental vulnerabilities, as poor public services, would increase the effect of these zoonoses within shantytowns.…”

Commensal Rodents in the City of Buenos Aires: A Temporal, Spatial, and Environmental Analysis at the Whole City Level

Commensal rodents are some of the main vertebrate pests in urban areas; however, knowledge about factors that favor them at large scales is scarce. We studied spatial and temporal variations in rodent infestation levels at the whole city scale using the complaints of rodent sightings and questionnaire surveys to city neighbors. Demographic, socio-economic, and environmental characteristics handled with a geographic information system were evaluated as possible indicators of rodent infestation. The number of rodent sightings was lower in months with low mean temperature with two months time lag and higher in areas with high number of meat and metal industries. Rodent infestation estimated by the questionnaire survey showed spatial autocorrelation defining large areas with similar infestation levels. It decreased when the apartment density increased, while increased when the proportion of area occupied by shantytowns, the density of meat industries, and the proportion of area occupied by moderate urban development increased. Rodent control programs at the whole city level would have better results if public health pest agencies and/or governments will focus the efforts on areas with more precarious conditions as well as the industrial areas in the cold season when have lower rodent abundances.
