OFFARM 123 E reservorio principal de Toxoplasma gondii es el gato doméstico (Felis catus), que por medio de los ooquistes que elimina con las heces, disemina la infección en el medio ambiente pudiendo transmitirla a multitud de animales, al hombre o incluso a pájaros y peces. La infección causada por este parásito pasa, en el hombre sano, casi inadvertida, pero no sucede lo mismo en individuos inmunodeprimidos en los que puede llegar a provocar la muerte. También el contraer la toxoplasmosis durante el embarazo entraña para la mujer, y principalmente para su feto, daños que pueden ser fatales pudiendo ocasionar abortos espontáneos o daños irreversibles en el sistema nervioso central del neonato. A pesar de los riesgos tan elevados que supone el contraer la toxoplasmosis para estos grupos y de que un individuo se pueda infectar después de una trasfusión sanguínea, ésta no es una enfermedad de declaración obligatoria.

Toxoplasma gondii infection and toxoplasmosis in farm animals: Risk factors and economic impact.

Prevalence and Risk Factors for Toxoplasma gondii Infection in Meat Animals and Meat Products Destined for Human Consumption

Toxoplasma gondii is a ubiquitous zoonotic pathogen belonging to apicomplexan parasites. Infection in humans and animals may cause abortion and other severe symptoms under certain circumstances, leading to great economical losses and public health problems. T. gondii was first discovered in China in 1955 and the corresponding work was published in 1957. Since then, a lot of work has been done on this parasite and the diseases it causes. This review summarizes the major progress made by Chinese scientists over the last 60 years, and gives our perspectives on what should be done in the near future. A wide variety of diagnostic approaches were designed, including the ones to detect T. gondii specific antibodies in host sera, and T. gondii specific antigens or DNA in tissue and environmental samples. Further work will be needed to translate some of the laboratory assays into reliable products for clinic uses. Epidemiological studies were extensively done in China and the sero-prevalence in humans increased over the years, but is still below the world average, likely due to the unique eating and cooking habits. Infection rates were shown to be fairly high in meat producing animals such as, pigs, sheep, and chickens, as well as in the definitive host cats. Numerous subunit vaccines in the form of recombinant proteins or DNA vaccines were developed, but none of them is satisfactory in the current form. Live attenuated parasites using genetically modified strains may be a better option for vaccine design. The strains isolated from China are dominated by the ToxoDB #9 genotype, but it likely contains multiple subtypes since different ToxoDB #9 strains exhibited phenotypic differences. Further studies are needed to understand the general biology, as well as the unique features of strains prevalent in China.

Seroprevalence and risk factors of Toxoplasma gondii and Neospora caninum infections in small ruminants in China.

Toxoplasma gondii is an important zoonotic pathogen infecting humans and almost all warm-blooded animals. The most common sources of human infection are ingestion of tissue cysts in raw or undercooked meat. However, limited information is available about T. gondii infection in horses and donkeys in China. In the present study, we report the seroprevalence of T. gondii infection in horses and donkeys in Liaoning province, northeastern China. Serum samples were collected from 711 and 738 slaughtered horses and donkeys, respectively, in 13 regions of Liaoning province. The modified agglutination test (MAT) was used to test the specific antibodies to T. gondii. In this study, 178 of 711 (25.0%) horses were seropositive for T. gondii with titers of 1:25 in 81, 1:50 in 62, 1:100 in 33, and 1:200 in 2, and seroprevalence of T. gondii infection from 13 regions ranged from 8.2% to 37.0%. Antibodies to T. gondii were found in 174 of 738 (23.6%) donkeys with titers of 1:25 in 66, 1:50 in 54, 1:100 in 49, and 1:200 in 5, and seroprevalence varied in 13 different regions, ranging from 9.1% to 32.6%. The results of the present study indicated that the rate of infection with T. gondii in horses and donkeys is a little high in Liaoning province, northeastern China in comparison to other surveys in China, which suggests that consumption of horse and donkey meat in this area may represent a potential source for human infection with T. gondii.

There is a lack of information regarding the prevalence of Toxoplasma gondii infection in sheep from northeastern China. In the present study, serum samples from 566 domestic sheep were collected from Liaoning Province, northeastern China, to investigate the prevalence of T. gondii antibodies using an indirect hemagglutination antibody test. Twenty-five of 566 samples (4.4%) were seropositive at the cutoff of 1:64 serum dilution. No difference was found among 6 geographic regions (P > 0.05). This is the first report of T. gondii infection in sheep in Liaoning Province.

In recent years, surveys of Toxoplasma gondii infection in dogs have been reported throughout the world, including China. However, information is lacking regarding the prevalence of T. gondii infection in pet dogs in northeastern China. In the present study, we report the seroprevalence of T. gondii in pet dogs in Shenyang, northeastern China. Sera samples from 328 pet dogs in 5 districts were examined for T. gondii antibodies with an indirect hemagglutination antibody (IHA) test; 10.0% tested seropositive. There were no significant differences in terms of sex, age, and locality (P > 0.05). The results indicate that infection by T. gondii is widely prevalent in pet dogs in Shenyang, northeastern China, which has potential implications for public health in this area.

Seroprevalence of Toxoplasma gondii Infection in Pet Dogs in Shenyang, Northeastern China

In recent years, worldwide surveys of Toxoplasma gondii infection in dogs have been reported. However, only limited surveys of T. gondii infection in police dogs have been available, including China. In the present study, we report the seroprevalence of T. gondii in police dogs in Shenyang, northeastern China. Sera from 291 police dogs were examined for T. gondii antibodies with the modified agglutination test (MAT), and 30.9% animals were tested seropositive. The results of the present study indicated a relatively high prevalence of T. gondii infection in police dogs in Shenyang, China.

This is the first report of T. gondii infection in sheep in Liaoning Province. Toxoplasmosis is a widely prevalent zoonotic disease, caused by Toxoplasma gondii. Domestic cats and other felids are the only definitive hosts for the parasite, and almost all warm-blooded animals, including sheep and humans, are intermediate hosts. Humans can be infected by ingestion of raw, or undercooked, meat from the infected animals, and by consuming food or water contaminated with oocysts excreted by cats (Dubey, 2010). Meat from T. gondii-infected livestock (including pigs, cattle, and sheep) is consumed widely in many countries, including China, and is known to be the primary source of infection for humans (Smith, 1991).
