Feral trichinosis in Africa

Abstract: 1. 1) In this preliminary note the results are given of the examination of 537 animals from the area in Kenya where Forrester et al. (1961) described an outbreak of human trichinosis. 2. 2) T. spiralis larvae were found in a dog (Canis familiaris) and a leopard (Felis pardus) collected near Kerugoya on the lower slopes of Mount Kenya. The dog had eaten part of a wild pig (Potamochoerus porcus) which was believed to be the source of the human infections. It is known that leopards also eat wild pigs. 3. 3) Four hundred and thirty-seven rodents and more than 50 carnivores which are known to eat rodents were examined; none was infected. 4. 4) T. spiralis larvae were found in a hyaena (Crocuta crocuta) from the Masai plains more than 100 miles from Kerugoya. 5. 5) Trichinosis is believed to be rare in the tropics. There are no previous records of infections in wild animals in Africa. Man probably contracts trichinosis in Africa when he intrudes into a cycle confined to wild animals. The incidence and distribution of the infection in animals is not yet known.

Taeniasis and cysticercosis (Taenia saginata).

Abstract: Publisher Summary This chapter summarizes all significant matters concerning Taenia saginata (T. saginata) taeniasis and cysticercosis—that is, nomenclature, host relationships, structure and biology, clinical and therapeutic features, epidemiology and epizootiology, and prevention of infection. It considers some taxonomic problems and the hosts of T. saginata. The structure and biology of the adult worm, egg, onchosphere, and cysticercus is discussed. The clinical aspects of taeniasis are dealt in terms of symptomatology, clinical pathology, diagnosis, and treatment. Yomesan is the drug of choice for T. saginata infection in Man at present, and some suggestions are made for treatment with this and other drugs. The chapter discusses epidemiology, epizootiological, and losses due to taeniasis and cysticercosis. Losses are difficult to estimate, because infection is rarely fatal, but some figures are available for European, African, and American areas. Meat inspection is dealt with as a means of prevention, likewise serological diagnosis and the immunization of cattle. Sanitation is a matter discussed, its improvement, expensive but connected with higher standards of living.
