Abstract | Cysticercus tenuicollis (C. tenuicollis) bubble-like metacestode is the larval stage of Taenia hydatigena (T. hydatigena). This larval stage was found in different numbers with various sizes from one cm up to 6–8 cm, which attached to the omentum, mesentery, and liver surface among domestic intermediate ruminant hosts. Prevalance of C. tenuicollis at Matrouh abattoir was 387(19.5%) cases out of 1986, 318 out of 1431 (22%) in goat compared to 69 out of 555 (12%) of sheep. Studying the effect of different viability duration days of C. tenuicollis cysts was estimated and different infective dosage of C. tenuicollis cysts to yield defined numbers of T. hydatigena adult worms in the small intestine of experimentally infected dogs. The study was carried out through faecal samples diagnosis, administration of C. tenuicollis cysts and measurement of T. hydatigena adult worms. Administration of 54 C. tenuicollis cysts to 36 healthy labeled experimental dogs. The healthy experimental dogs were divided according to C. tenuicollis cysts viability and different dosage into 3 groupsÍž Group 1 (viability within 24 hours), Group 2 (viability within 48 hours), and Group 3 (viability within 96 hours) and each viability groups were divided into two dosage one or two C. tenuicollis cysts which contains each dosage six experimental dogs three females and three males. The results indicated that the over all of total infected dogs were 16/36 (44.44%) experimentally infected with C. tenuicollis and the females were higher than males as 10/16 (62.5%) were females. the infection was 100% within 24 hours (group1) with two cysts infective dose among female only with the shorter average length than males and overall infection among within 24 (group 1) was 8/12(66.66%). On other hand, the low infection rate to yield adult worms among viability duration within 96 (group 3), was 3/12 (25%) but the infection rate within 48 (group2) was 5(41.66%) out of 12 experimental infected dogs So, it could be concluded that, the risk of infection of Taenia hydatigena adult worm among experimental dogs was belonged to infective dosage two C. tenuicollis cysts with viability duration within 24, prevention of dogs from consumption of abattoir offal’s within 24 hours, or before treatment is a must in controlling the disease.
