ABSTRACT
A total of 205 blood samples were collected from different farm animals shortly before slaughtering [cows 50, buffaloes 40, sheep 60, goats 30 and calves 25] from the Alexandria abattoirs. In the mean time, a total of 95 blood samples were collected from individuals with expected high exposure rate such as butchers [35] and workers [60] who slaughtered, eviscerated, dressed and skinned such animals. At the same time, a total of 108 blood samples were collected from individuals of normal exposure groups such as poultry breeders [20], laboratory workers [25], nurses [15], housewives [18] and students [30]. All blood samples were examined serologically by using Dye test for detection of toxoplasma infection. A total of 35 faecal samples were obtained from stray domestic cats around the abattoirs to investigate the epidemiological role of the cats in the transmission of Toxoplasma gondii. From the obtained results it was revealed that seropositive cases in animals [cows, buffaloes, sheep, goats and calves] were 23.5% and in individuals of high risk group [butchers and workers] were 41.1% and other groups of normal exposure [poultry breeders, laboratory workers. nurses, housewives and students] were 17.6%, and the mature infective Toxoplasma gondii oocysts were revealed from cat's faeces with an incidence of 20.0%. The zoonotic and public health importance of Toxoplasma gondii was discussed
