“…Toxoplasma gondii seroprevalence in dogs from Foz do Iguaçu county (67.02%) is close to the upper limit found in Paraná in the last decade: 10.3% and 70.85% (DREER et al, 2013;CALDART et al, 2015;FERREIRA et al, 2016). Even though no epidemiological variables were statistically associated with this high prevalence, dogs that did not have access to the street, slept in the house and has a defined breed showed a higher frequency in the IFAT methodology.…”

“…To IFAT, the methodology was done according Camargo (1964), where tachyzoites of RH strain were used as antigen, and in each slide positive and negative controls were used. Samples with titers ≥16 were considered positive (FERREIRA et al, 2016) and were diluted at a ratio four until the titer was negative. The results of the two tests were merged to analysis.…”

This study evaluated the seroprevalence of Toxoplasma gondii, Neospora caninum and Leptospira spp. in dogs from Foz do Iguaçu, Paraná, Brazil. Indirect immunofluorescent antibody test was used to detect antibodies anti-T.gondii and anti-N. caninum. Immunoenzymatic assay and microscopic serum agglutination were used for screening antibodies anti-T.gondii and anti-Leptospira spp., respectively. The results were: 67.02% of the samples reactive for T.gondii and 1.38% for N. caninum, both without statistically significant variables. For Leptospira spp. the results indicated seroprevalence of 23.11%. The analysis of the variables without distinction of serovar showed association for intrinsic characteristics as breed, age, nutritional status and dog category. The extrinsic variables as city region and access to the street presented association (p<0.05). The most prevalent serovars were: Canicola 59.47%; Bratislava 13.07% and Butembo 15.68%. Variables that make up the adjusted multiple analysis model using Leptospira spp. were: age, breed and nutritional status; serovar Canicola, sex, nutritional status and area (p<0.05); serovar Bratislava, lymphadenomegaly and presence of fleas (p<0.05). Given the results obtained, dogs can be used as sentinels for toxoplasmosis and leptospirosis in Foz do Iguaçu and other cities with similar outcomes. In addition, preventive measures should be taken by health authorities because they are zoonoses and humans are also at risk.

“…Infection by T. gondii in dogs is most often asymptomatic and may result in neurological changes in immunosuppressed animals (MORETTI et al, 2002;SILVA et al, 2009). Ferreira et al (2016) observed higher frequency of neurological signs (p < 0.0001) such as seizures, ataxia, paresis, and plegias as compared with ophthalmic, reproductive, and respiratory signs.…”

Toxoplasmosis, leishmaniasis, and ehrlichiosis are zoonoses that have cosmopolitan distribution and cause important clinical changes in dogs and humans. Dogs are important in the epidemiology and transmission of Leishmania infantum and Ehrlichia canis and serve as indicators of environmental contamination by the transmission of Toxoplasma gondii. The aim of this study was to detect antibodies against T. gondii, Leishmania spp., and E. canis in dogs from Bahia and identify the risk factors associated with infections. Blood samples were collected from 353 dogs from several municipalities of Bahia and the sera were tested using reaction of indirect immunofluorescence (RIFI) for T. gondii and Leishmania spp. and enzyme-linked immunosorbent assay (ELISA) for E. canis. The data were tabulated and analyzed using EPI-INFO 7.1.5 program. Of 353 samples analyzed, 144 (40.8%) were positive for T. gondii (antibody titer 16-4,096) and 92 (26.1%) were seropositive for Leishmania spp. (antibody titer 40-160). The seropositivity for E. canis was the highest as compared to that of the other agents. Furthermore, 184 (52.1%) samples were positive for antibodies against E. canis. Sixteen (4.5%), 71 (20.1%), and 25 (7.1%) samples were co-infected with T. gondii and Leishmania spp., T. gondii and E. canis, and E. canis and Leishmania spp., respectively, while 20 (5.7%) dogs presented co-seropositivity for all three etiological agents. Risk factors such as age, sex, habitat (stray/not stray), and region of dog’s origin were analyzed; age ( ? 1 year) was significantly associated with T. gondii (p = 0.03) and E. canis (p = 0.02) infection and stray animals were more exposed to T. gondii (p = 0.03) and Leishmania spp. (p = 0.01) infection. The results confirmed the heterogeneous distribution of the three etiological agents in dogs from Bahia and identified animals with co-infections.

Exploring similarities and differences between Toxoplasma gondii and Neospora caninum infections in dogs

Toxoplasma gondii and Neospora caninum infections in dogs are predominantly manifest asymptomatic. However, these infections can also present highly varied and potentially severe clinical signs. This is due to the parasites’ ability to replicate in a number of cell types within the host organism, with N. caninum exhibiting a particular tropism for the central and peripheral nervous systems, and T. gondii targeting the central nervous system and musculature. In clinical practice, toxoplasmosis and neosporosis are often considered to be closely related diseases, despite their distinct epidemiological, clinical, diagnostic, and therapeutic characteristics. The present review analyses the similarities and differences between these two protozoan infections, since an accurate and timely aetiological diagnosis is essential for establishing effective therapeutic protocols and control strategies.
