Zoonoses in humans from small rural properties in Jataizinho, Parana, Brazil

Abstract

The aim of this study was to conduct a serological survey for Lyme diseases, brucellosis, leptospirosis and toxoplasmosis and identify the risk variables related to these zoonoses in humans living in the rural area of Jataizinho, state of Parana, Brazil. A total of 63 rural properties were surveyed. Additionally, 207 serum samples collected from these rural area inhabitants were tested for indirect immunofluorescence (IFI) and western blots (WB) were performed to detect Borrelia burgdorferi (sensu lato); a tamponated acidified antigen test (AAT) and 2-mercaptoethanol (2-ME) were used to detect antibodies of Brucella abortus; the microscopic agglutination test (MAT) was carried out to detect antibodies anti-Leptospira spp. and IFI was used to find antibodies of Toxoplasma gondii. Two of the samples (0.96%) were reactive for Lyme borreliosis, three (1.4%) for brucellosis, 25 (12.1%) for leptospirosis and 143 (69.1%) for toxoplasmosis. Although the town of Jataizinho has a human development index (IDH) that was considered to be average (0.733) in the state of Parana, the low social, economic and cultural conditions of the population from small rural properties have resulted in lack of basic information on animal health and direct or indirect contact with the various species of domestic animals, wildlife and ticks have probably contributed to the prevalence levels found. These results show the need for additional regional studies in order to determine the epidemiological characteristics of these diseases as well as their respective vectors and reservoirs so that effective prophylaxis can be administered in the human population.

A serological survey of agents causing leptospirosis and toxoplasmosis in Rattus rattus in the city of Umuarama, northwest Paraná, Brazil

“…There is only a short distance between the perimeter of the peri-urban region where the rodents were captured and some rural properties, and the people and animals residing in these properties are susceptible to infection. Individuals working directly with animals, such as farmers, veterinarians, rural workers, and slaughterhouse workers, can reportedly acquire leptospiral infection through contact with contaminated urine, milk, aborted fetuses, carcasses, or placentas (WASIŃSKI; DUTKIEWICZ, 2013;GONÇALVES et al, 2013). Indeed, Clazer (2016), studied the same micro-region as this study and observed the presence of antibodies against the Hardjo serovar in the sera of 50% of university students enrolled on a veterinary medicine course.…”

First record of Borrelia burgdorferi sensu lato antibodies in stray dogs in the Northwest Region of Parana State, Brazil

“…in humans was also studied in the northwest region of Parana state. Using WB technique, Gonçalves et al (2013a) detected the presence of anti-B. burgdorferi s.l.…”

“…However, few studies were conducted using Western Blot (WB) to confirm the presence of B. burgdorferi s.l. infection, as recommended by the Center for Diseases Control and Prevention (CDC) (ALVES et al, 2004;CARRANZA-TAMAYO et al, 2012;DANTAS-TORRES, 2008;GONÇALVES et al, 2013a;JOPPERT et al, 2001;YOSHINARI et al, 2010). The aim of this study was to determine, by indirect immunofluorescence (IFI) and western blot (WB), the presence of anti-B.…”

Survey of spatial distribution of vector-borne disease in neighborhood dogs in southern Brazil

“…antibodies in human samples were reported in a rural settlement of northern Paraná state, however without molecular evidence of infection . Also within the Paraná state, the first detection of antibodies against B. burgdorferi sensu latu was reported in human beings living in the same rural area (Gonçalves et al, 2013). Finally, the adequate clinical and laboratory health status observed among these neighborhood dogs may http://www.openveterinaryjournal.com C. Constantino et al Open Veterinary Journal, (2017), Vol.…”
