“…It is likely that workers that have handled infected animals were carrying the parasite from their contaminated hands to their mouths. In a study of 174 workers and residents of swine workers in the USA, Weigel and coworkers [12] attributed an increased risk of T. gondii seropositivity in males to less attention paid to cleanliness in food preparation and eating. Workers in contact with animals might be more frequently in contact with T. gondii than subjects without contact with animals.…”

“…Only few descriptive studies about the seroprevalence of T. gondii infection in people occupationally exposed to animals including veterinarians [10,11] and farmers [12] have been reported. However, to the best of our knowledge, there is no any case-control study that had determined the association between T. gondii infection and occupational exposure to live animals.…”

The association of infection with Toxoplasma gondii and occupational exposure to animals has been scantly determined. We performed a case-control study with 200 subjects from Durango Province, Mexico, occupationally exposed to animals and 200 ageand gender-matched subjects without this occupation. Sera from all participants were analyzed for anti-T. gondii IgG and IgM antibodies using enzyme-linked immunoassays. The association of seroprevalence with sociodemographic, work, clinical, and behavioral characteristics in cases was determined.Cases and controls had similar frequencies of anti-T. gondii IgG antibodies (12/200: 6.0% and 11/200: 5.5%, respectively) (OR = 3.0; 95% CI: 0.12-73.64; P = 1.0). The frequency of sera with high (>150 IU/ml) levels of anti-T. gondii IgG antibodies was comparable among cases and controls (P = 0.61). Seroprevalence of anti-T. gondii IgM antibodies was similar in cases (4, 2.0%) than in controls (4, 2.0%) (P = 1.0). Multivariate analysis showed that seropositivity was associated with eating while working (OR = 7.14; 95% CI: 1.91-26.72; P = 0.003) and consumption of duck meat (OR = 5.43; 95% CI: 1.43-20.54; P = 0.01).No association between seropositivity to T. gondii and occupational exposure to animals was found. However, risk factors for infection found should be taken into account to reduce the exposure to T. gondii.

Infectio 2017. http://dx.doi.org/10.22354/in.v21i2.654 AbstractToxoplasma infection, an aspect included in the Integral Care Guidelines for prevention, early detection and treatment of complications during pregnancy developed and sponsored by the Department of Science, Technology and Innovation, Colciencias and the Ministry of Health and Social Protection; was selected to develop recommendations that may contribute to its prevention diagnostic and treatment. Guidelines were developed through systematic review of literature, two panels of evaluation, gradation of evidence: SIGN (Scottish Intercollegiate Guidelines Network), discussion panel with users and patients, external evaluation and socioeconomical evaluation of the impact of recommendations. The Toxoplasma gondii infection that occurs during pregnancy may cause serious complications for the fetus and important sequelae for the newborn. A clinical guideline based on the best available scientific evidence, with emphasis on Colombian references, was performed. Experts in parasitology, neonatology and infectious diseases (adult and pediatric) developed the recommendations. It is suggested that the recommendations included in this guideline be followed by healthcare professionals in pregnancy care programs nationwide, with the purpose of lowering the morbidity and mortality related to this disease. Specific recommendations for diagnosis during the first trimester of the pregnancy, recommendations for prevention in noninfected women, identification of fetal or newborn infection and recommendations for treatment in those given cases are included.

“…There was not significant relation between pregnant women who worked in the garden around their houses with toxoplasmosis infection incidents (p=0.29 > 0.05). Weigel et al (1999) 16 found different result in Europe, almost 17% pregnant women infected by toxoplasmosis because of contacts with soil. Similar result also found by Spalding et al (2005) 17 who stated that contacts with soil were high risk factor of toxoplasmosis infection for pregnant women.…”

Background: toxoplasmosis is a zoonotic-parasite disease caused by T.gondii that spread in many countries. Recently, this disease is one of the major public health problems associated with severe enocomical and social impacts such as miscarriages, hydrocephalus, blindness and mental retardations. The human parastic infection are closely related with the presence of infected cats around their houses, in which the animals are the definitive host releasing the parasites into the environment via their feces. The aim of this research was to determine the correlation between morphological prevalence and molecular detection of T.gondii in cats feces. Methods: detection of molecular was carried out by applying microscopic and a specific polymerase chain reaction (PCR). A case-control study using 40 maternal with positive serology of T. gondii and 40 maternal with negative serology were selected by purposive sampling method. Similarly, 80 faecal sample of cats were also obtained from each house of the women. The major risk factors considered as the important rule for human toxoplasmosis such as age, education, occupation, contact with soil, cat's age, un-owned cats and oocyst-positive feces were determined by questionnaire. Results: The epidemiological analysis showed that the highest risk factor was oocyst-positive feces (OR= 8.143; p= 0.003), followed by education (OR= 3.414; p= 0.045), contact with soil (OR= 2.255; p= 0.073), un-owned cats (OR= 2.25; p= 0.210), age (OR=2.23; p=0.074), occupation (OR= 1.556; p= 0.348) and cat's age (OR= 1.138; p= 0.799). However, the pregnant women with serologically positive to T. gondii had a very high probability of miscarriages (OR= 18.857; p= 0.0001) compared to whom with serologically negative. Moreover, logistic regression model analysis revealed that only oocyst-positive feces and education contributed a significant factor in causing toxoplasmosis among pregnant women. Microscopic observation of 80 faecal samples indicated that only 14 (17.5%) contained typical oocyst of T. gondii. All of the 8 oocyst of T. gondii positive-faecal samples were further confirmed with PCR, and we found that 4 (50%) were positive. Conclusion: This study concluded that the presence of oocyst-positive feces in the environment in conjuction with education level were considered to play significant contribution to the accident of toxoplamosis in pregnant women.
