“…On the other hand, few studies showed higher percentages, for example, Teixeira (2008) detected seropositivity in 62.37% of dogs in the milk producing properties of Maranhão, and Benetti et al (2009) reported positivity in 66.7% of the dogs inhabiting dairy farms in Mato Grosso. In contrast with the results of this study, Brasil et al (2018) reported a frequency of 1.6% anti-N. caninum IgG in dogs of the urban areas of João Pessoa, PB. When compared to the frequency of anti-N. caninum antibodies in dogs of urban areas, higher prevalence of antibodies in rural dogs was observed.…”

Article history Neospora caninum is a protozoan of the heteroxenous cycle, whose definitive hosts include domestic and wild canids, while intermediate hosts are herbivores. Its occurrence in dogs of rural areas deserves attention due to the risk of transmission to the animals of production, mainly cattle. The objective of this study was to determine the prevalence of N. caninum antibodies in dogs belonging to rural areas of the municipality of Sousa, the semi-arid region of Paraíba, Northeastern Brazil. Blood sera from dogs of six rural communities were analyzed. The indirect fluorescent antibody test was performed for the detection of anti-N. caninum IgG. The results were considered positive when the total peripheral fluorescence of the tachyzoites occurred at a dilution ≥1:50. The frequency of seropositivity was 9.18% (9/98 cases). Antibody titers ranged from to 200, with the 1:50 titer being predominant. Among the evaluated sites, 66.6% (4/6) showed the presence of at least one seropositive dog. The variable contact with cattle was considered a risk factor (odds ratio = 15.25) for infection by the parasite, demonstrating a higher risk of contact with contaminated tissues. It was concluded that dogs from rural areas of the municipality of Sousa were exposed to N. caninum, and it was suggested that contact between dogs and cattle be avoided as a control measure to prevent infection in dogs.

“…This questionnaire included epidemiological variables related to general information about the animal's lifestyle and management. To identify possible risk factors for T. gondii infection in these animals, the following variables were selected: sex [52,86], age [5,65], breed [6,56], street access [9,67], contact with cats [12,66], presence of rodents [48], type of food (dry and wet commercial food, meat and embedded, homemade food, offal and other types of food, like fruits and vegetables) [14,79] and water source for animals' consumption [8].…”

“…High anti-T. gondii antibody frequencies have been reported in domestic dogs and cats from Cuba, Mexico, Panama, Iran, Argentina, Portugal, Australia, Colombia, and Chile [1,10,26,30,44,57,58,63,83,86]. In Brazil, the frequency of T. gondii infection in Brazilian pet animal populations can vary from 9 to 70% in dogs and from 0 to 71% in cats [5,9,35,47,50,68,81]. Toxoplasma gondii seropositivity in pets can vary, not only between countries, but also between regions of the same country, and areas of the same city [20].…”

“…In general, domiciled animal populations or under the responsibility of owners have a lower frequency of anti-T. gondii antibodies compared to stray or shelter populations [4,18,47,55,77,79]. Different risk factors for T. gondii infection have been identified in populations of domestic dogs and cats, including street access, contact with cats, and presence of rodents at home [2,9,12,48,64,66,67,73]. Among these factors, the type of diet of these animals stands out.…”

Toxoplasma gondii in domiciled dogs and cats in urban areas of Brazil: risk factors and spatial distribution

et al. 2021

Toxoplasma gondii is a highly prevalent zoonotic parasite in Brazil capable of infecting mammals and birds. The increase in the urban populations of pets and the narrowing of the human–animal relationship can facilitate the transmission of important public health zoonoses, such as toxoplasmosis. This study aimed to evaluate the frequency and spatial distribution of T. gondii infection and its risk factors in domiciled dogs and cats attended at the Jorge Vaitsman Institute, Rio de Janeiro. Serum samples from 400 dogs and 272 cats were evaluated by an indirect fluorescent antibody test (IFAT) for IgG anti-T. gondii antibodies. Epidemiological questionnaires were used to interview the animals’ owners to identify risk factors for infection. Of the total, 34% (136/400) of dogs and 8.1% (22/272) of cats had anti-T. gondii antibodies. Breed (OR: 2.10–95%, CI 1.27–3.46) was a risk factor for dogs, while sex (OR: 3.40–95%, CI 1.10–10.52) and homemade food consumption (OR: 8.49–95%, CI 2.48–29.05) were risk factors for cats. Offal consumption was considered a risk factor for both species evaluated (OR: 2.74–95%, CI 1.38–5.43 for dogs; OR: 7.66–95%, CI 1.24–47.29 for cats). The spatial analysis showed that T. gondii seropositive animals were widely distributed in the metropolitan region of Rio de Janeiro state, with a concentration observed mainly in the west and north zones of Rio de Janeiro city. The results emphasize the importance of adopting prophylactic measures to control T. gondii transmission in domiciled dogs and cats in Rio de Janeiro, contributing positively to public health.

“…Information about the epidemiology of neosporosis and toxoplasmosis has been reported in several places in Brazil, proving the widespread circulation of these protozoans (Acosta et al, 2016;Brasil et al, 2018;Cerqueira-Cézar et al, 2017;Langoni et al, 2014). The presence of anti-N. caninum antibodies has also been reported in different animals, including cattle and dogs, in the state of Mato Grosso (Benetti et al, 2008;Benetti et al, 2009;Boa Sorte et al, 2015;Melo et al, 2012;Rodrigues et al, 2016).…”

Tis study evaluated the presence of Neospora caninum and Toxoplasma gondii antibodies in 320 domestic dogs living in urban and rural areas of the municipality of Poconé, located in the Pantanal wetlands of the state of Mato Grosso, Brazil. Anti-N. caninum (cut-of point 50) and anti-T. gondii (cut-of point 16) antibodies were detected by means of immunofuorescence assays (IFA), using NC-Bahia and RH strains as antigens, respectively. Anti-N. caninum antibodies were detected in 69 (21.56%; 95% CI: 17.27%-26.56%) dogs, 31 (44.93%) of which lived in urban areas and 38 (55.07%) in rural areas, and endpoint titers ranged from 50 to 3200. Anti-T. gondii antibodies were found in 132 (41.25%; 95% CI: 35.84%-46.87%) dogs, 58 (43.94%) from urban areas and 74 (56.06%) from rural areas, and endpoint titers ranged from 16 to 8192. A total of 33 dogs (10.3%) (12 urban and 21 rural animals) reacted to both agents (P <0.05). Tis study showed a higher prevalence of anti-T. gondii compared to anti-N. caninum antibodies in the dogs living in the Pantanal region, suggesting that both protozoans circulate in the studied region. Tis information is relevant, in view of its implications for animal and public health.
