Abstract
Toxoplasmosis is a parasitic disease caused by Toxoplasma gondii and affecting all warm-blooded animals. The available data about the epidemiological situation of T. gondii in water buffaloes in Egypt are scarce. Thus, a cross-sectional study was conducted to determine the seroprevalence of T. gondii in water buffaloes in three Egyptian governorates and to evaluate the associated risk factors for the infection. A total of 430 sera samples were examined using commercial Indirect ELISA Multi-species kit. The overall seroprevalence rate of T. gondii in examined water buffaloes was 7.4 %, and the highest rate (9.3 %) was found in Kafr ElSheikh governorate. Multivariate logistic regression analysis showed that adult buffalo (OR = 7.10; 95 % CI: 0.87-57.68; P = 0.067) and small herds (OR = 8.42; 95 % CI: 1.07-66.02; P = 0.043) were more likely than young buffalo and large herds to become infected with T. gondii. Moreover, the risk of buffaloes contracting T. gondii infection was higher in winter and especially among animals contacted with cats. It is necessary to identify risk factors in order to determine what mitigation, control, and prevention strategies to implement in order to reduce, control, and prevent T. gondii infection in domestic animals, which will in turn reduce human infection with the disease.

Abstract
Toxoplasma gondii is an obligate intracellular parasite that causes toxoplasmosis, with approximately one third of the population around the world seropositive. The consumption of contaminated food is the main source of infection. These include meat products with T. gondii tissue cysts, and dairy products with tachyzoites. Recently, contamination has been detected in fresh products with oocysts and marine products. Despite the great health problems that are caused by T. gondii, currently there are no standardized methods for its detection in the food industry. In this review, we analyze the current detection methods, the prevalence of T. gondii in different food products, and the control measures. The main detection methods are bioassays, cell culture, molecular and microscopic techniques, and serological methods, but some of these do not have applicability in the food industry. As a result, emerging techniques are being developed that are aimed at the detection of multiple parasites simultaneously that would make their application more efficient in the industry. Since the prevalence of this parasite is high in many products (meat and milk, marine products, and vegetables), it is necessary to standardize detection methods, as well as implement control measures.

Abstract
Toxoplasmosis is a parasitic disease resulting from infection with the apicomplexan Toxoplasma gondii (Nicolle et Manceaux, 1908), one of the world's most common parasites in warm-blooded animals, including humans. Sources of infection can be exposed to infected cat faeces, mother-to-child transmission during pregnancy, and notably, the consumption of undercooked contaminated meat of intermediate hosts. In Thailand, water buffaloes are highly valued for rice cultivation, traditional culture and meat production. Like several other mammalian species, these animals play a role as reservoirs of T. gondii, thus representing a threat to human health. The seroprevalence of T. gondii infection in swamp buffaloes was examined in southern and northeastern Thailand. In total, serum samples of 721 water buffaloes were collected from seven provinces (Ubon Ratchathani, Roi Et, Si Sa Ket, Surin, Buri Ram, Sakon Nakhon, and Songkhla) and examined for the presence of T. gondii infection using commercial latex agglutination test kits (TOXOCHECK-MT, Eiken Chemical Co., Tokyo, Japan). Of the 721 animals analysed, 49 (6.8%) were positive for T. gondii. Songkhla province had the highest seroprevalence (14.7%) among the seven provinces covered in this survey. There was a potential risk to local citizens of T. gondii infection identified by the present study, notably in northeastern Thailand, where despite lower seroprevalence consuming raw buffalo meat salad should be restricted to avoid the risk of zoonotic infections.

Abstract
Toxoplasmosis is a zoonotic disease of global distribution and importance. It is caused by the protozoan parasite Toxoplasma gondii, the only species in the Toxoplasma genus. This parasite can infect most warm-blooded animals, including humans and livestock. Main routes of transmission are by ingestion of tissue cysts in raw or undercooked meat of infected animals, ingestion of raw vegetables or water contaminated with T. gondii oocysts from cat feces, and transplacental. Around one-third of human beings are chronically infected with T. gondii. Most infections appear to be asymptomatic in immunocompetent persons, but toxoplasmosis can be fatal to the fetus and immunocompromised adults. Water and foodborne outbreaks have been caused by this parasite worldwide, but few are well documented. Importantly, T. gondii is a parasite of high importance in animal health, causing reproductive failure, particularly in small ruminants, and clinical toxoplasmosis in many species. This overview discusses the knowledge of T. gondii infections in the last decade focusing on the foodborne transmission of this parasite.

Abstract
Toxoplasmosis and neosporosis are diseases with worldwide distribution that are associated with reproductive problems in livestock and responsible for economic losses. This review presents an overview of the current knowledge relative to these diseases in water buffalo (Bubalus bubalis). In general, buffalo are considered resistant to clinical toxoplasmosis because there are studies only reporting serological evidence of natural infection in these animals. Studies have described age, poor hygienic status of the farm, and presence of cats as risk factors for the development of Toxoplasma gondii infection in buffalo. It must be highlighted that buffalo meat, which does not receive adequate freezing treatment, could be a potential source for toxoplasmic human infection as well as the importance of raw buffalo milk in the transmission of toxoplasmosis to human beings. Neospora caninum is considered one of the major causes of abortion and responsible for huge economic losses in cattle. Vertical transmission is the main route to infect calves, and is responsible for maintaining the parasite within a herd. In buffalo, vertical transmission is also described; moreover, although there are indications that N. caninum may be associated with abortion in dairy buffalo, the reproductive importance of neosporosis is apparently lower in buffalo relative to cattle. Most studies have identified a higher time of exposition to N. caninum oocysts relative to age. The household system was also described as a risk factor for infection, possibly due to persistent contact between the home-raised buffalo and canids. The fetal immune competence of buffalo is similar to bovine, and buffalo fetus are highly susceptible to infection during the first trimester of pregnancy, indicating that N. caninum may be an abortigenic agent in buffaloes. Alternatively, it is interesting to note there is evidence that the inflammatory response in pregnant buffalo infected with N. caninum is mild enough to avoid abortion in most cases. It is proposed that the possible transmission of toxoplasmosis through unprocessed milk and buffalo meat may occur, which is important in terms of public health. Additionally, there is strong evidence to suggest that N. caninum may be associated with abortion in buffalo.

Abstract
One hundred twenty-four water buffaloes (Bubalus bubalis) originating from 9 farms located in southern Italy were tested to investigate simultaneously, for the first time, the seroprevalence of the protozoa Neospora caninum, Toxoplasma gondii and Besnoitia besnoiti by ELISA tests and to evaluate the clinical findings potentially associated to the presence of these aborting parasitic pathogens. Twenty-five of 124 buffaloes (20.2%) were positive for N. caninum, while 17/124 (13.7%) for T. gondii. No buffalo showed specific antibodies for B. besnoiti. Nineteen of 124 animals (15.3%) were found seropositive for both T. gondii and N. caninum. The univariate statistical analysis showed that the seroprevalence of N. caninum is significantly associated with abortion and presence of retained foetal membranes, while the seroprevalence of T. gondii is significantly associated with an increase of days open. The logistic regression models showed that the co-infection by N. caninum and T. gondii strengthened the abortive effects (OR = 7.330) and showed further negative effects on the parameter embryonic death (OR = 2.607). The outcome revealed herein represents a high exposure of N. caninum and T. gondii in water buffaloes with reproduction disorders that deserves attention for both economic reasons, animal health and welfare.
