Abstract:
This study was conducted to assess the contamination of soil and the
environmental load with Toxoplasma gondii- like oocysts from cats'
faeces, which will also give an idea about the prevalence of
Toxoplasmosis in cats. Also the study investigated the prevalence of the
disease among humans in Red Sea State, Sudan.
The soil contamination and the disease in cats was investigated through
examining cats' faecal samples from different areas of the State, for the
presence of Toxoplasma gondii-like oocysts, using the improved modified
McMaster Method. Thirty four (34%) out of the 100 cats' faecal samples
examined were positive for the presence of T. gondii-like oocysts. A result
indicating a wide spread contamination of environment with T. gondii
oocysts, and a very high prevalence of Toxoplasmosis in cats.
In humans, the disease was investigated serologically, using Latex
Agglutination tests. The overall prevalence was 44.4% (52 out of 107
persons), being 50% among women and 41.1% among men while all
children examined randomly were negative for the presence of antibodies
against T. gondii.
