SUMMARY:

This work is divided into three chapters written in the format of scientific articles. The first one consists of a scientometric study, with the objective of tracing the profile of articles published on zoonoses transmitted by rats (Ratus sp.), through scientometrics. A search for publications was carried out in the scientific databases: WEB OF SCIENCE and SCIELO, using different combinations of names related to the theme, “Health AND Zoonoses AND Rats”. Studies corresponding to the years 2015 to 2020 were considered. The articles obtained were analyzed and grouped according to the number of publications per year, list of journals in which the articles were published, main authors who published in the period, subjects addressed in the publications, country with the highest publication rate, main agents of rats studied and journal qualis. As a result, there is a moderate amount of research on rat-borne zoonoses worldwide. However, it is noticeable that these studies are increasing when comparing the years 2015 to 2020 with a gradual increase over the years. Among the countries with the highest number of publications, the United States and Brazil stand out. The second article addresses intestinal parasites in rats, aiming to verify and identify the occurrence of gastrointestinal helminths in rats sp. For this, the research was carried out from May to June 2022, and the collection was carried out in points of the city of Santarém in which the presence of rats sp. synanthropic activity can be evidenced, being them in the “Mercadão 2000”, “Feira da Candilha”, Bosque da Cidade, UFOPA campus Tapajós area and ZooUnama peripheral zone, for that the rats sp. were sampled for a period equivalent to 4 collections each month. The maximum number of specimens of rats sp. possible, regardless of species, sex, age, reproductive stage. Then, the animals were removed from the traps directly with the hand and gloves. Subsequently, these were placed in cages and taken to the laboratory, where they were sacrificed for screening, identification and blood collection of the animals. The animals were euthanized with an overdose of lidocaine, as recommended by the National Council for the Control of Animal Experimentation (CONCEA). The animals were necropsied in locu. After the necropsy of the animals, samples of feces were collected from the intestine, aiming to identify intestinal parasites. The parasites were identified using the spontaneous sedimentation technique. Data were statistically analyzed to verify the absolute and relative frequency. Thus, it was noted that Ancylostoma spp. was the most commonly observed species, being present in 57.89% of the positive samples, followed by Enterobius spp and Hymenolepis spp, both with 18.75% each. It was possible to observe the presence of Ancylostoma spp. in 53.33% (8/15) of the evaluated stool samples. When analyzing stool samples from Ratus ssp. was to observe that 86.66% (13/15) of the samples were positive for at least one gastrointestinal parasite. Therefore, the findings evidenced in this study indicate that synanthropic rodents present in the municipality of Santarém, Pará, Brazil, are parasitized by different species of gastrointestinal parasites with zoonotic potential. The third chapter aimed to identify possible hemoparasite of interest in public health through blood smears. The research was carried out from May to June 2022. With the result, the presence of Dirofilaria spp., Leishmania sp., Babesia sp., Anaplasma sp., and Erlichia sp., in rats sp. synanthropes in the municipality of Santarém, Pará, Brazil.
