“…The prevalence of T. gondii in dogs that lived in the areas where the rats were captured is compatible with the one found in other studies conducted in the Paraná State ranging from 19.7% to 75.98% in dogs from urban areas and from 20.8% to 84.1% in dogs from rural areas 33 , 34 , 35 , 36 . In this study we should also associate the difference in the prevalence of toxoplasmosis observed among rats and dogs, with the fact that the predominant rodent population in the city was of R. rattus ; a species that presents arboreal habits and is only found in the ground when searching for food.…”

SUMMARYThe role of rodents in the epidemiology of toxoplasmosis was investigated in Londrina, Paraná State, Brazil. One hundred and eighty-one Rattus rattus and one Mus musculus were caught in 37 places. Blood and tissues were collected and submitted to the indirect fluorescence antibody test (IFAT) and the bioassay. Serum samples from 61 contacting dogs were also collected. Sixteen rats (8.8%) were positive for Toxoplasma gondii, but just two of them were positive by serology and bioassay test. Antibodies were found in nine (4.9%) rats. Tissues of nine rats bioassayed were positive and four isolates were obtained. Restriction fragment length polymorphism (RFLP) analysis was performed using 12 markers (SAG1, SAG2, SAG2-alt, C22-8, C29-2, L358, PK1, BTUB, GRA6, SAG3, Apico, CS3). Genotyping revealed that the four strains isolated from this study have been isolated before in cats and chickens from Brazil. None of the isolates was identified like clonal archetypal T-types I, II, and III. The rats presented lower serologic Toxoplasma gondii prevalence (8.8%) compared to contacting dogs (70.5%).

“…The presence of infection by T. gondii in dog populations shows environmental contamination by oocysts eliminated by cats or contamination of food given to these animals. This highlights a possible risk of infection to the human population- as they share the same habitat 33 , 34 , 35 , 36 .…”

“…Previously, increased prevalence rates were observed in areas around forests (Mascolli et al, 2015) and rural areas compared with urban areas (Boa Sorte et al, 2015;Benitez et al, 2017a). The seroprevalence rates of T. gondii were high in this study, suggesting that preying upon infected animals may be an important factor in maintaining infection in the canine population, as previously observed (Navarro et al, 1992;Camossi et al, 2008). The chance of dogs becoming infected with T. gondii is exacerbated due to their close contact with soil and their carnivorous behavior (Dubey & Jones, 2008), preying on rodents and birds (Mascolli et al, 2015).…”

Dogs are hosts of the protozoans Toxoplasma gondii, which causes an important public health disease, and Neospora caninum. Studies that have evaluated toxoplasmosis and neosporosis for prolonged periods in dog populations are rare. We analyzed infection by both parasites in a domestic dog population over three consecutive years in São Paulo state, Brazil. In the 1st, 2nd and 3rd years of collection, 181, 193 and 172 domiciles were visited, and blood samples of 331, 371 and 348 dogs were collected for antibody serology, respectively. The seroprevalence of T. gondii in each year was 27.2%, 22.5% and 43.9%, respectively, and that of N. caninum was 7.8%, 4.8% and 6.8%, respectively. The incidence rates for T. gondii in the 2nd and 3rd collections were 13.2% and 30.0%, and those for N. caninum were 3.3% and 4.4%, respectively. Positive and negative serological conversions for both agents occurred at high frequencies during the study period. This study reveals the canine population’s serological profile and demonstrates the constant exposure of dogs to the investigated pathogens, indicating the need for prevention and control measures in the region.
