Seroprevalence of Cysts in Cattle, Human Hospital Cases, and Risk Factors for Human Taeniasis in Kajiado County, Kenya.

is a zoonotic tapeworm that causes diseases in cattle and humans. A cross-sectional survey was conducted between June and July 2021 in Kajiado County, Kenya, to estimate the seroprevalence of cysts in cattle presented for slaughter in Kitengela, Kiserian, and Keekonyokie slaughterhouses; determine the annual hospital reported cases of in humans that visited all level 4 hospitals in Kajiado County between 2015 and 2021; and assess the risk factors for in humans. Analyzed data in this study revealed that the seroprevalence of cysts in cattle in the selected slaughterhouses was 2.

Ultrastructural study of Echnococcus granulosus larval forms.

The larval forms of Echinococcus granulosus were surgically removed from Turkana hydatid patients and studied on the electron microscope. It was found that the larval forms "hydatid cyst" consists of a protective laminated layer that surrounds the germinal layer. The germinal layer is made up of numerous germinal cells that transform to brood capsules within which protoscolices are formed.

Cellular immunity to Echinococcus granulosus cysts.

A fundamental feature of Echinococcus granulosus infection is its chronicity. There are many reasons for this, including weak natural immunity and the ability of the larval stages to evade or resist elimination by the hosts' specific immune responses. To identify the types of hosts' cellular immune response, a series of ultrastructral studies of hydatid cysts surgically removed from Turkana patients was conducted based on transmission electron microscopy.
