“…In the present study, 25.4% of the tested samples were positive by IFAT and were within the State range from 19.7 to 33.1% (Brito et al 2002, Souza et al 2003, Langoni et al 2006) and the national range from 8.2 to 88.5% (Silva et al 1997, Souza et al 2003, Cañón-Franco et al 2004, Azevedo et al 2005, Romanelli et al 2007, Figueredo et al 2008, Da Silva et al 2009, Santos et al 2009 (Silva et al 1997, Brito et al 2002, Azevedo et al 2005, Langoni et al 2006, Dubey et al 2007b,c, Öncel et al 2007, Romanelli et al 2007, Da Silva et al 2009, Santos et al 2009). On the other hand, Cañón-Franco et al (2004) observed that most of the 76.4% seropositive dogs did not have low titers, ranging from 128 to 2048, which may indicate active infection.…”

“…However, some studies have reported that dogs can mechanically transmit oocysts through the feces to men (Frenkel & Parker 1996, Lindsay et al 1997, Clementino et al 2007). On the other hand, dogs epidemiologically act as perfect sentinels of T. gondii infection to men, allowing the evaluation of the rate of environmental contamination with oocysts in both urban and rural areas, as well by ingestion of raw or undercooked meat with tissue cysts (Souza et al 2003, Azevedo et al 2005, Langoni et al 2006, Santos et al 2009). Santos et al (2009) demonstrated such relationship by identifying 54/61 (88.5%) dogs and 113/116 (97.4%) men serologically positive to T. gondii in 50 farms studied in Mato Grosso State, Brazil.…”

“…Such variable is a very important item in Brazil since most of the population is used to feeding dogs on leftovers, which are generally raw or poorly cooked food of unsafe origin. In addition, there are precarious sanitary conditions, including scarce technical knowledge about infections important to public health and raising of pets (dogs and cats), as well as production animals in the house and surroundings, concomitantly (Santos et al 2009). The presence of cats, when studied, generally shows a significant association, as observed by Azevedo et al (2005).…”

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...

“…Cows showed 29.1% (35/120) of prevalence for T. gondii. Seroepidemiological surveys for toxoplasmosis in cattle showed anti-T. gondii antibody occurrence ranged from 1.03 to 71% in Brazil (MARANA et al,1995;GONDIM et al, 1999;GARCIA et al, 1999;SANTOS et al, 2008;MOURA et al, 2010;FRAZÃO-TEIXEIRA & OLIVEIRA, 2011), and 0 to 91% in some parts of the world (DUBEY & STREITEL, 1976;HASHEMI-FESHARKI, 1996;MORE et al, 2008;OPSTEEGH et al, 2011). Therefore, caution should be taken when the results of prevalence studies are being evaluated, since the differences in results might be directly related to the serological techniques employed, the cut-off values, sample size, and the type (breed and/or species) of animal that is being investigated.…”

Companion animals can harbor a wide range of parasites, some of which are transmissible to humans. The overall burden of human diseases attributable to companion animal -associated parasites is unknown and varies greatly between regions. The risks associated with some are often overstated while others are largely ignored, and the range of illness can extend from mild and selflimited to fatal.
