“…Prevalence of T. gondii in free range and slaughterhouse chickens were reported as 53.6% and 24%, in Brazil and 53.3% and 20%, in Egypt, respectively, and the prevalence of free range chickens in Nicaragua, Indonesia, Middle East, and Illinois (based in the United States) was reported as 85.7%, 26.6%, 40.4%, and 100%, respectively (Dubey, ). In studies conducted by Askari et al, in Shiraz City (Fars Province Center), seroprevalence of toxoplasmosis in free, semi‐industrial and industrial chickens was 27.1%, 12%, and 2.02%, respectively (Asgari et al, ). The difference in the prevalence of toxoplasmosis in the present study and Askari et al is due to the difference in the type of sample studied, the diagnostic method and the weather conditions.…”

Birds are important intermediated hosts of Toxoplasma gondii. Consumption of chicken meat and its infected products is one of the main sources of human infection with T. gondii. However, little information is available about T. gondii infection in egg. In this study, the contamination of industrial and local eggs with Toxoplasma was investigated by PCR method targeting the RE gene in two tropical cities of Iran. Genotypes of T. gondii were determined by PCR‐RFLP method targeting the SAG3 gene. T. gondii DNA was detected in 11% (22/200) of the eggs. Genotyping of 14 T. gondii isolates revealed that all of the isolates were belonged to genotype III of T. gondii. Sequencing of the isolates by the SAG3 gene showed 95%–100% similarity with the T. gondii isolates in GenBank. Practical applications The findings of this study suggested that consumption of raw or undercooked eggs might play a role in human infection with Toxoplasma. Hence, consumption of adequately cooked eggs should be considered for prevention of human toxoplasmosis.

“…This result was lower than that obtained by Dubey et al (1994) who found T.gondii in 6/13 (34.6%) of livers, 7/13 (53.8%) of lungs and 7/14 (50%) of brains in infected Japanese quail. The parasite distribution in bird tissue is random; so, the negative result should be interpreted carefully because it is possible that the parasite could be present in unexamined parts of the target tissue (Asgari et al, 2008).…”

This study aimed to detect Toxoplasma gondii in quail samples collected from different houses in Sohag Governorate by histopathological examination and determine the seroprevalence of IgM and IgG in aborted women using ELISA test. The results revealed that 10% of quail samples were positive for Toxoplasma gondii, 48.9 % of aborted women were seropositive for IgM (5.4%), IgG (38%) and both IgM and IgG (5.4%). Higher infection rate was reported in age group ranging from18 to 20 years, in women with first time of abortion and in women live in rural areas. This study highlights on the role of quail as a source of Toxoplasma infection for human.

“…Many factor such as the locality, the number of birds, and the type and the hygiene of breeding affect the incidence or seroprevalences of T. gondii in domestic avian species (Dubey, 2010). For example, the seroprevalence of T. gondii antibodies among freeranging chickens was 27.1% in Southern Iran (Asgari et al, 2008) and 40.4% in Giza Province of Egypt (Dubey et al, 2003a),…”

This review article was developed to the infection of avian species with Toxoplasma gondii (T. gondii), diagnosis, pet bird and human infection, and control methods with a special reference to the current status of infection among the Egyptian poultry farms and population. Toxoplasmosis is a zoonotic disease caused by a unicellular, protozoan parasite T. gondii. Different domesticated and wild animals, as well as birds can harbor T. gondii and may be a potential source of infection to humans. Avian species could be infected with T. gondii through the ingestion of contaminated food, soil, and water with oocysts shed in the excreta of infected animals, especially cats. Poor sanitation and hygienic conditions increase the risk of infection. Consumption of food or water, as well as undercooked poultry meat or meat products containing the oocysts of the parasite, are the main sources of human infection with T. gondi. Diagnosis of T. gondii in the infected host depends on the serological detection of specific antibodies and molecular detection of the parasite. Microscopic demonstration of the oocysts and other developmental stages of the parasite in the intestine, liver, brain, and skeletal muscles tissues is another means for rapid diagnosis. Generally, a high prevalence of the disease is also reported in pet birds. Toxoplasmosis in humans is associated with abortion, congenital disorders, stillbirth, and other complications, especially in immunocompromised patients. Application of hygienic measures, as well as public awareness, are essential for the prevention and control of toxoplasmosis. In different Egyptian governorates, a high prevalence of T. gondii has been detected in animals, birds, and humans. High incidence of infection was recorded due to the contact with Toxoplasma oocysts shed mainly from infected cats or other carriers. Egyptian chicken and turkey flocks and backyard birds revealed the presence of different developmental stages of the parasite and even its antibodies. In addition, human populations showed signs of toxoplasmosis with severe complications.
