“…As serological tests we used the modified agglutination test (MAT), a well-established in-house immunofluorescence test (IFAT) and an ELISA based on TgSAG1 (p30-ELISA (Maksimov et al, 2011)) as proposed by the European Food Safety Authority for the analysis of swine (EFSA, 2011).…”

“…Affinity purified 30 kDa T. gondii surface antigen (TgSAG1; Hosseininejad et al, 2008;Maksimov et al, 2011) was diluted in bicarbonate buffer (0.1 M, pH 8.3) and 120 μl/well of the diluted antigen (30 ng/ml) used to sensitize (1 h, 37°C) PolySorp ELISA plates (Nunc, ThermoFischer Scientific, Denmark). The plates were then washed three times with phosphate buffer saline (PBS) supplemented with 0.05 % (v/v) Tween® 20 (Serva, Heidelberg Germany) (PBST).…”

“…This intensification of farming is associated with changes in farm management such as year round indoor-housing of dairy goats. In pigs and poultry, a lower seroprevalence of T. gondii infection was found in indoor farming systems than in outdoor farming systems (Maksimov et al, 2011;van der Giessen et al, 2007). Therefore, indoor-housed dairy goats are expected to have a low seroprevalence of T. gondii.…”

After extensive review of the literature, experimental studies were performed in the main livestock species (cattle, small ruminants, pigs, horses and poultry) to address the main knowledge gaps considering (1) the relationship between detection of antibodies and presence of T. gondii, (2) the anatomical distribution of tissue cysts, and (3) on-farm risk factors for infection. In slaughterhouse studies in cattle and horses, a lack of concordance between detection of antibodies by MAT and detection of T. gondii in tissues by mouse bioassay or MC-PCR was demonstrated. Positive mouse bioassay results were obtained in cattle and horses, indicating a potential infection risk for consumers.

Calves, sheep, pigs, chickens and turkeys were experimentally infected with T. gondii. In calves various tissues were tested and T. gondii was recovered, but no clear predilection sites were identified. There was also little variation in parasite load between the different edible tissues (i.e. skeletal muscles) from pigs and sheep. Brain and heart were clearly identified as predilection sites in chickens and turkeys, with higher parasite loads compared to breast, thigh and drumstick muscle. The observation that drumstick, an edible tissue, tested positive in 25% (8/32) of the bioassay positive organic laying hens, indicated a potential risk for consumers. The seroprevalence of T. gondii in Dutch indoor-housed dairy goats appears to be relatively low and was associated with the presence of cats at the farm. I...

“…Goose meat is an important foodstuff worldwide, and humans can acquire infections with T. gondii by ingesting undercooked goose meat containing tissue cysts. Surveys of seroprevalence of T. gondii infection in geese have been reported throughout the world [6][7][8], and there have also been surveys of T. gondii infection in geese in several provinces of China in recent years [9,10]. The People's Republic of China (PRC) is one of the largest producers of geese in the world, and Hainan province, tropical China is one of the major geese producers in the PRC.…”

Background: Little information is available about the seroprevalence of Toxoplasma gondii infection in geese (Anser domestica) in China. In the present investigation, the seroprevalence, risk factors and genotyping of T. gondii in geese were investigated in Hainan province, tropical China. Findings: A total of 600 serum samples and 150 brain tissue samples were collected from six administrative regions in tropical China, and assayed for T. gondii antibodies by Indirect Haemagglutination (IHA) test. Genomic DNA was extracted from the 30 brain tissues of seropositive geese and T. gondii B1 gene was amplified using a semi-nested PCR. DNA samples giving positive B1 amplification were then genetically characterized using multi-locus PCR-RFLP. Overall, 17% (95% CI: 14-20) of the animals were positive for T. gondii antibodies. Presence of cats in the household (odds ratio, OR 3), hygiene (OR 2.3) and presence of stray cat around the house (OR 2.3) were considered as main risk factors associated with T. gondii infection. Of 30 DNA samples, three were positive for the T. gondii B1 gene, two showed complete genotyping results. Only one genotype (type II) was identified. Conclusions:The results of the present survey indicated the presence of T. gondii infection in geese in tropical China. Therefore, it is imperative that improved integrated measures be carried out to prevent and control T. gondii infection in geese in this province. This is the first report documenting the occurrence of T. gondii genotype in geese in China.

“…Also the 2-yearold breeders (Group 4) were found to be seronegative and this can only be explained by an effective housing system where biosecurity is strictly enforced and feed is not contaminated with oocysts. Zhu et al (2008), Yan et.al (2009 and Maksimov et al (2011) have reported similar findings amongst biosecurity-enforced, caged and freerange poultry in North East China and enclosed and free-range geese and ducks in Saxony, Germany. Both reports relate high T. gondii seroprevalence in free-range birds due to their exposure to feral cats.…”
