Abstract
The aim of this study was to identify the presence of different parasites in synanthropic rodents captured in the urban and peri-urban area in the city of Umuarama, Paraná (PR). The rodents were euthanized for measurement and collection of feces and ectoparasites. Specific identification keys were used for the ectoparasitological analysis and the technique by Hoffman et al. (1934) was used for the coproparasitological analysis. From the 162 rodents captured, 24.70% were found in the urban area and 75.30% in the periurban area in the city. The rodents belonged to the species Rattus rattus (96.91%) and Rattus norvegicus (3.09%), being 52.47% male and 47.53% female. 62.96% analyzed feces samples contained at least one parasite species. Identified parasites species were Syphacia sp., Aspiculuris sp., Strongyloides sp., Hymenolepis diminuta and Entamoeba sp. and protozoa eggs. Upon visual inspection, a total of three (1.85%) ectoparasites identified as Xenopsylla cheopis were collected. The importance of synanthropic rodents on the maintenance and possible transmission of different parasitic etiological agents with zoonotic potential was demonstrated, making both man and pets susceptible to possible parasitic infections. Key words: Diagnosis, ectoparasites, enteroparasites, feces, rats.
Highlights
Rodents belong to the Rodentia order and there are approximately 2,000 rodent species in the world and they live in any terrestrial environment that can provide conditions for their survival (Brasil, 2002) and some species are considered synanthropic to man because they change their environments by their actions (Brasil, 2002; Guimarães et al, 2014)
The capture of 162 synanthropic rodents was performed throughout a year with possible catches in all months, which indicates that the locations where the traps were assembled provided favorable conditions for the survival of this animal species
(2002), its action radius tends to be greater than the one for Rattus norvegicus due to its ability of scale vertical surfaces and the ease of walking on wires, cables and tree branches, which makes it a species that is more prone to capture
Summary
International License which can be found in the urban, peri-urban and rural areas of the cities Factors such as urbanization and overcrowded cities and inadequate sanitation (water and sewer), have led to increasing numbers of these animals and becoming increasingly common transmitted diseases (Brasil, 2002). In Brazil, studies have been done in the states of Paraná (PR) and Sergipe (SE) (Araujo et al, 2010; Guimarães et al, 2014) These studies have shown the importance of synanthropic rodents in the transmission of different parasitic diseases of zoonotic potential chain. Considering the absence of regional data and the importance of rodents as transmitters of parasitic agents with zoonotic potential, the aim of this paper was to identify the presence of different parasite species in synanthropic rodents captured in the urban and periurban area in the city of Umuarama, Paraná, Brazil
