ABSTRACT
Toxoplasma gondii is an obligate intracellular coccidian that infects human being, warm blooded animals and birds. The life cycle cannot be completed without passing in the feline species which shed millions of un-sporulated oocysts. The oocysts become infectious after sporulation 2-5 days later and contaminate the surrounding environment with subsequent oral infection of final and intermediate hosts. The hazard played by kittens was evaluated by detecting the cats infected percent as bio-indicator to what extent the degree of Egyptian environmental contamination by T. gondii oocysts occurs. A total number of ninety seven kittens, 34 and 63 stray and house-hold cats respectively were collected from different regions of Giza, Cairo and Kalubia Governorates. All cats were assayed serologically by using Latex agglutination test [LAT] and Sabin Feldman Dye Test [SFDT]. The results were re-tabled after cats were reclassified to 72 and 25 un-weaned and weaned kittens respectively. Sero-positive percent of naturally infected Egyptian kittens was 70.6 and 50.8% while the shedding percent was 4.17 and 0% in un-weaned and weaned kittens respectively. Sero-negative kittens were better shedders [11.34%] than sero-positive ones [3.09%]. Significant difference was also recorded between stray vs house hold vs female's kittens. Oocysts environmental contaminations maximize the incidence of human toxoplasmosis through the infection of slaughtered food animals which harboring tissue cysts. This necessitates control of urban outdoor cats inhabitants to reduce the risk of infection to human and animals

In this study, blood samples were collected from 16 symptomatic patients at hospital and 12 asymptomatic individuals working at the swine slaughter house. Blood samples were also obtained from 75 pigs at two abattoirs and experimentally infected rats [day 25 PI]. There was no great difference in the seroprevalence of trichinellosis between symptomatic [56%] and asymptomatic [50%] individuals. ELISA results recorded that 13% of swine was seropositive, while 44% were suspected to be infected with T. spiralis. Immunoblotting profiles of T. spiralis adult antigen against human, swine and rat sera showed common reactive bands at 95.00 and 64.466 kDa [human and swine] and 35.554 kDa [human and rat]; while, the blotting patterns of adult E/S products against human, swine and rat antibodies recognized two trichinellosis-specific determinants between human and swine [87.619 and 74.136 kDa] as well as between human and rat [98.00 and 16.535 kDa]
