“…CHIEFFI et al 10 and SCHANTZ et al 37 , reported a higher frequency of infection in individuals who were in contact with dogs, however, other studies found no association between ownership or professional contact with dogs and Toxocara infection 22,26 . FAN et al 18 observed high seropositive rates in 79.4% of dog owners, and 67.9% in nonowners, suggesting that these two groups are equally at risk of infection. These results are in line with those of WOODRUFF et al 42 who observed that 50% of patients with clinical toxocariasis owned dogs.…”

SUMMARYTo estimate the frequency of anti-Toxocara sp. antibodies, and evaluate factors associated with this infection, sera from 242 male and female children, aged from one to fifteen years old, attended at the Hospital of the Federal University of Uberlândia, Minas Gerais State, Brazil, were analyzed by ELISA. Information on the patients was collected and registered using an investigative questionnaire, and details on possible clinical alterations were obtained from the medical charts of 187 patients. Of a total of 242 samples, 21 (8.7%) were positive for anti-Toxocara sp. antibodies. The presence of dogs and cats and the school variable (place of contact), appeared to be significantly associated (p < 0.05) with a positive serology. Respiratory symptoms and eosinophil counts greater than 20% also showed a positive statistical correlation with a positive serology for Toxocara sp.. Factors such as sex and age, and symptoms like headache, stomach ache, convulsive crises and anemia were not associated with toxocariasis.

“…in 38.8 % of healthy children and observed a statistically significant correlation between occurrence of antibodies and low hygiene practices. Fan et al (2004) reported up to 75.6 % of seropositive healthy children living in Taiwan, in an environment contaminated by eggs of Toxocara spp. Kaplan et al (2004) detected a substantially higher seroprevalence in groups of mentally disabled persons (18.8 %) than was that in a sample of healthy individuals (7.1 %).…”

261 SummaryThe aim of our study was to determine the prevalence of toxocariasis in Bratislava and smaller towns in western Slovakia. During 2006 -2011, sand samples collected from 121 sandpits were investigated: 63 sandpits were from Bratislava City and 58 from sandpits in towns outside Bratislava (Malacky, Pezinok Stupava). In Bratislava, 27 % of examined sandpits were contaminated with Toxocara spp. eggs. In smaller towns eggs of Toxocara spp. were found from three sandpits (6.8 %) of Pezinok and Stupava only. In Malacky, no faeces and no eggs were found in any sandpits. Faecal samples of 1436 dogs and 263 cats were investigated. T. canis eggs were found in the faeces of 16.5 % dogs and T. cati in 18.6 % of examined cats. Toxocariasis of dogs was significantly higher in smaller towns such as the city Bratislava (χ2 = 10.88 for P ≤ 0.001). The difference in prevalence of T. cati in cats bred in Bratislava and outside Bratislava was not confirmed (P ≤ 0.05). 382 pregnant women were examined by ELISA. Anti-Toxocara antibodies were detected in 32 women (8.4 %). The difference in seroprevalence of women coming from Bratislava (6.6 %) and smaller towns outside Bratislava (11.0 %) was not statistically significant (χ2 = 1.6; P ≤ 0.05).

“…Clinical manifestation of human toxocariasis is usually asymptomatic (2,4). Nevertheless, visceral larva migrants (VLM) and ocular larva migrants (OLM) as two major syndromes of toxocariasis in human can be detected (6,7). VLM signs are recognized by fever, hepatomegaly, splenomegaly, respiratory symptoms, muscle pain, hypergammaglobulinemia, and eosinophilia (2,7,8).…”

Background: Humans may be accidently infected by larva stage of Toxocara canis and Toxocara cati nematodes through consumption of contaminated vegetables and food by embryonated eggs and geophagia. They cause visceral, ocular, and neurological syndromes detected through serological methods. Parasitic contamination and infectious diseases are the main cause of eosinophilia. Objectives: The current study aimed at investigating Toxocara canis seroprevalence in military personnel and their families with eosinophilia referred to a military hospital in Tehran, Iran, from 2015 to 2016. Methods: In the current cross sectional study, 179 patients (military personnel and their families) referred to a military hospital with eosinophilia > 5% in a two-year period (2015 -2016) were selected and after obtaining informed consent and filling out the questionnaires, anti-Toxocara canis IgG was detected in their sera using the enzyme-linked immunosorbent assay (ELISA) technique. Results: Seroprevalence of Toxocara canis infection was 11.7%. Males were the most infected individuals. After statistical analysis, a significant relationship between the level of education (P = 0.01) and history of pet contact (P = 0.02), and anti-T. canis IgG was found; nevertheless, it had no relationship with age, gender, occupation, and place of residence (P > 0.05). Conclusions: Prevalence of Toxocara antibody was relatively high, which can indicate susceptibility to Toxocara infection in military personnel due to military operations. Due to lack of clinical manifestations in some patients, survey of Toxocara infection in eosinophilia cases is recommended.
