Taenia saginata

A species whose larvae live in cattle. The adult worm lives in the small intestine of humans, who acquire it by eating insufficiently cooked beef infested with the encysted larval form (cysticercus or bladderworm). Adult worms may reach a length of 15 to 20 ft (4.6 to 6.1 m) or longer.

Wikerhauser (1982), al inmunizar bovinos contra Taenia saginata concluyo que sobrenadantes de oncosferas incubadas in vitro contenian antigenos protectores similares a aquellos producidos por oncosferas inyectadas; pero que su eficiencia dependia de la cantidad mas que en su calidad (Flisser et al., 1982).

The prevalence of intestinal parasitic infection during the period of study was as follows; Ascaris lumbricoides (n= 205, 1.8%), Giardia lamblia (n= 178, 1.6%), Entamoeba histolytica(n= 174, 1.57%), Trichuris trichiura (n= 118, 1.06%), Hymenolepis nana (n= 51, 0.46 %), Enterobius vermicularis (n= 28, 0.25%) and Taenia saginata (n= 21, 0.19%) respectively.
O complexo teniase-cisticercose constituise de duas doencas distintas, causadas pela mesma especie de cestodeo, em fases diferentes do seu ciclo biologico, sendo a teniase caracterizada pela presenca das formas adultas de Taenia solium ou Taenia saginata no intestino delgado do ser humano.
