  A large number of mammals are hosts of taeniidae cestodes. Nematotaenia dispar was the only worm isolated from the infected gray monitor in Saudi Arabia. The present study was used to examine, the electrophoretic patterns of extracted proteins of Nematotaenia dispar isolates from Varanus griseus by using SDS-PAGE technique. The whole worm was washed with phosphate buffered saline (PBS, pH 7.4), weighed and homogenized by glass-glass homogenizer in cold physiological saline. Supernatants were examined by Sodium Dodecyl Sulfate-Polyacrylamide Gel Electrophoresis (SDS-PAGE) and coomassie blue staining. The SDS-PAGE of the extracted proteins resulted in a total of eleven protein molecules were detected in gel, six bands with apparent molecular weights of 200, 116, 97, 66, 45 and 29 kDa were observed. It is concluded that the present results may give an idea about this worm that we can do antibodies for one of these proteins to be used in the future. In addition, further studies on the functions of these proteins are required.

  A cross-sectional study was conducted to identify the seroprevalence of Toxoplasma gondii infection in cats, dogs, sheep, goats, cattle and camels in Al-Ahsa area, Saudi Arabia. Serum samples were collected from cats, dogs and slaughtered ruminant animals and analysed for Toxoplasma gondii antibodies using ELIZA. The seroprevalence was 90, 20, 19, 10, 22, 12, 4 and 8% in stray and household cats, stray and household dogs, sheep, goats, cattle and camels, respectively. Significantly higher value of prevalence was seen in stray cats compared to other animals. The presence of Toxoplasma gondii in slaughtered animals indicates that toxoplasmosis in this area poses an occupational risk to workers in the slaughter house and that toxoplasmosis could be a veterinary public health that necessitates integrated control measures.
