“…First, human can acquire T.gondii by eating raw or inadequately cooked infected meat, especially pork, mutton, and wild game, or uncooked foods that have come in contact with infected meat (Dubey, 1994). Second, humans can inadvertently ingest oocysts that cats have passed in their faeces, either from a litter box or from soil (e.g.…”

Toxoplasmosis, caused by the protozoan parasite Toxoplasma gondii, is one of the most common parasites of man and other warm-blooded animals. Humans are infected through contaminated food, water, and blood transfusion, organ transplantation or from mother to foetus through the placenta. Severe congenital infections occur as a result of primary T. gondii infection in early pregnancy. Transmission of T.gondii to the foetus can result in serious health problems, including mental retardation, seizures, blindness and death. Frequency of foetal infection is higher when maternal infection occurs later in pregnancy and sequelae are more severe when maternal infections occur early in the first trimester of pregnancy. The ability of the parasite to survive intracellularly largely depends on the blocking of different proapoptotic signaling cascades of the host cells. During pregnancy, however, alterations in the incidence of apoptosis are associated with abnormal placental morphology and function. Both cellular and humoral immune responses control T.gondii infection. Toxoplasma is asymptomatic, infected women can only be detected by serological testing. In many instances, congenital toxoplasmosis can be prevented by educating pregnant women and women of childbearing age about the route of transmission. The need for screening suspected cases of T. gondii will help reduce transmission to the foetus.

“…Toxoplasmosis is a zoonosis caused by the obligate intracellular parasite protozoan Toxoplasma gondii, which has worldwide distribution and infects most warm-blooded animals, including pets and man (Dubey 1994). The infection prevalence varies with the different species depending on occurrence area, socio-cultural habits, besides weather and geographic factors.…”

RESUMO.-[Fatores de risco e presença de anticorpos para Toxoplasma gondii em cães do litoral do Estado de São Paulo.] A toxoplasmose é causada por um protozoário parasita intracelular obrigatório, Toxoplasma gondii, e acomete vertebrados homeotérmicos incluindo animais de companhia e o homem. O cão apresenta importância epidemiológica por atuar como sentinela da infecção para o homem. O presente estudo objetivou determinar a ocorrência de anticorpos para T. gondii em 205 amostras de soro de cães do município de Ubatuba, SP, Brasil, pela reação de imunofluorescência indireta (RIFI), assim como os fatores de risco relacionados à infecção nos animais, como raça, idade, sexo, acesso a rua, ingestão de comida caseira, acesso a água não tratada e presença de roedores. 52/205 (25,4%) Toxoplasmosis is caused by the obligate intracellular protozoan parasite Toxoplasma gondii and affects warm-blooded vertebrates, including pets and man. Dogs are epidemiologically important since they act as sentinels for the infection in humans. The present study aimed to determine the presence of antibodies to T. gondii in 205 serum samples from dogs in Ubatuba, Sao Paulo state, Brazil, through indirect immunofluorescence reaction (IFAT), as well as the risk factors related to toxoplasmosis in the animals such as breed, age, sex, access to outdoors, homemade food ingestion, access to untreated water, and contact with rodents. Toxoplasmosis-positive samples accounted for 52/205 (25.4%), with titers ranging from 16 to 256. The serological results presented significant association (P<0.05) with homemade food ingestion (45/118; 38.1%; CI95% 29.9%-47.2%) (OR=7.0; CI95% 3.0-16.6), and with access to outdoors where those that do not have access to the street were prevalent (37/121; 30.6%; CI95% 23.1%-39.3%) (OR=0.5; CI95% 0.2-1.0). These results show that toxoplasmosis in this region is related to problems of sanitary education, mainly concerning the appropriate cooking of foods, since most positive animals did not show significant association with the presence of rodents or untreated water consumption but showed, instead association with ingestion of homemade food. Thus, toxoplasmosis is a public health problem in the studied region, and sanitary measures are needed to control the infection due to the strict relationship between man and dog and the presented risk factors. e acesso a rua, em que aqueles que não tinham acesso a rua foram prevalentes (37/121; 30,6%; IC95% 23,1%-39,3%) (OR=0,5; CI95% 0,2-1,0). Estes resultados demonstram que a toxoplasmose na região está relacionada com problema de educação sanitária, principalmente quanto ao adequado cozimento dos alimentos, visto que a maioria dos animais positivos não apresentou associação significativa com presença de roedores ou consumo de água não tratada, porém os mesmos permaneciam em casa aos quais fora oferecida comida caseira. Portanto, a toxoplasmose consiste em um problema de saúde pública na região estudada, sendo necessárias medidas sanitári-as para o controle da infecção, visto a...
