“…[ 18 ], Mosa [ 19 ], and Ossani et al . [ 22 ]. The low numbers of incidence of T. gondii detected by qPCR in comparison with antibodies of Toxoplasma are due to the fact that IgG antibodies are produced in the late stage of infection, and the parasite is being in localized in the organs and tissues and not circulated in the blood, thus finally it will not reach to the milk.…”

Background and Aim:Toxoplasmosis is a worldwide zoonotic disease with harmful effects on animal and human health. Ingestion of contaminated raw milk has been suggested as a vehicle for transmission of Toxoplasma gondii to human. The present study was performed for the detection of T. gondii in raw milk samples of goat, sheep, and camel in Upper Egypt using two different techniques (enzyme-linked immunosorbent assay [ELISA] and quantitative polymerase chain reaction [qPCR]).Materials and Methods:This study was conducted to determine the T. gondii prevalence using ELISA and qPCR in raw goat, sheep, and camels milk (30 samples for each) collected from different locations in Upper Egypt.Results:T. gondii IgG antibodies were detected in 90.0, 60.0, and 3.33% of goat, sheep, and camel milk samples, respectively. From the positive samples of T. gondii IgG, the parasitic DNA was detected only in two examined milk samples, one of them was present in goat milk sample and another one was found in sheep milk sample. On the other hand, the parasite was not detected in camels’ milk samples.Conclusion:These results concluded that the raw milk was contaminated by T. gondii tachyzoites which could be a source of human infection. Restricted hygienic programs should be implemented in the animal farms to decrease the risk of milk contamination by this parasite.

“…They exhibited that the incidence of T. gondii in raw camel, sheep and goat milk samples were 0%, 5.55% and 3.70%, respectively. T. gondii has also been recognized in the milk of numerous hosts, such as goat [22][23][24][25][26][27], sheep [28][29][30], donkey [23,31], cattle [32,33], camel [21,[34][35][36], buffalo [11], cat [37], dog [38], rat [39] and even human breast feed [40,41]. In keeping with this, only consumption of contaminated goat milk was associated with occurrence of human acute toxoplasmosis [42][43][44].Nevertheless, some sero-epidemiological surveys specified significantly association with ingestion of raw milk of other livestock and T. gondii infection [45][46][47][48][49].…”

RIMARY infection by Toxoplasma gondii is habitually food borne and ingestion of foods with animal origins is measured as a risk factor. The current survey was performed to assess the seasonal and age distribution of T. gondii in diverse kinds of raw milk and traditional dairy products. Three-hundred and seventy raw milk and traditional dairy samples were collected and subjected to DNA extraction. B1 specific gene of T. gondii was perceived by means of the molecular technique. Eighteen out of 370 (4.86%) studied samples were positive for T. gondii. Molecular incidence of T. gondii in raw milk was 6.08%. T. gondii was also perceived in 2.85% of studied traditional dairy samples, respectively. Sheep milk (10%) and cheese (6.66%) had the uppermost molecular incidence of parasite. Molecular incidence of T. gondii in raw camel milk and cream and butter samples were 3.33%, 5% and 5%, respectively. Samples which were collected through autumn (15.55%) and summer (9.37%) seasons had the maximum molecular incidence of T. gondii. Raw milk samples of older than 4 years animal species (11.39%) had the maximum molecular incidence of T. gondii. The existingsurvey is the first report of seasonal and age distribution of T. gondii in diverse kinds of dairy samples. Raw sheep, goat, buffalo, bovine and camel milk and also traditional cheese, cream and butter dairy samples may harbor T. gondii infection. Seasonal and senile distribution should be measured for molecular incidence of T. gondii in milk of primary infected animals and also traditional dairy products.

“…Powell et al, Costa and Langoni, respectively reported, that cats and rat infected with T. gondii, their milk contained viable and transmitable T. gondii [29,30]. Conducted research and reported that T. gondii lives can be excreted in goat's milk and can survive in fresh cheese, while Bezerra et al and Ossani, et al found, respectively, 6.05% and 30.95% of the milk samples of naturally infected goats and dairy ewes were positive with T. gondii [20,[31][32][33][34].…”

Toxoplasmosis is a zoonotic disease caused by an intracellular protozoal infection, Toxoplasma gondii. Cats and Felidae are definitive host and non felidae mammals and birds as intermediate host. Worldwide, domestic cats are estimated to be infected with ranging from 30 to 40%. Cats produce and shed oocysts and contaminate the environment for long time. Sporulated oocyst is infectious stage for livestock and product (meat, milk and eggs) of infected livestocks can act as a source of T. gondii infection.
