Taenia saginata
Taenia saginata
Taenia saginata (/ˈtiːniə səˈɡɪnətə/), commonly known as the beef tapeworm, is a species of parasite that belongs to the cestode family. The term "Taenia" is derived from the Greek word "tænia", which means "ribbon", referring to the flat, ribbon-like body of the worm. "Saginata" is derived from the Latin word "saginatus", meaning "fattened", which refers to the worm's ability to grow and fatten within its host.
Life Cycle
The life cycle of Taenia saginata involves two hosts. The primary host is humans, who become infected by consuming raw or undercooked beef containing the cysticercus (larval stage) of the worm. The secondary host is cattle, which become infected by ingesting eggs present in the human feces.
Symptoms
Infection with Taenia saginata is often asymptomatic. However, when symptoms do occur, they may include abdominal discomfort, weight loss, and the passage of proglottids (segments of the worm) in the stool.
Treatment
Treatment for Taenia saginata infection typically involves a single dose of the anthelmintic drug praziquantel.
Prevention
Prevention of Taenia saginata infection primarily involves proper cooking of beef to kill the cysticercus, and good hygiene practices to prevent contamination of food and water with human feces.
