ABSTRACT

Bloodsmears from 119 yellow baboons (Papio hamadryas cynocephalus) in six groups in Mikumi National Park, Tanzania, and from 189 olive (P.h. anubis) hamadryas (P.h. hamadryas) and hybrid baboons in three groups in Awash National park, Ethiopia showed differing levels of infection with Hepatocystis simiae. 0% to 42% in the Tanzanian groups were carriers of the parasite but none of the Ethiopian baboons was positive. The remarkable absence of H. simiae in the Ethiopian baboons is believed to be related to environmental factors that exclude transmission in the absence of the Culicoides vector.

ABSTRACT

Blood smears of 159 vervet monkeys from three sites in Kenya were stained with Giemsa and examined for Hepatocystis parasites. The populations differ in incidence of parasitemia, ranging from 0-62% affected individuals. These differences are probably due to altitude and local environmental conditions.

ABSTRACT

Historical events and suitable environmental conditions in the southwestern coastal areas of Sri Lanka have led to the establishment of a zone of endemic filariasis caused by Wuchereria bancrofti and transmitted by Culex pipiens fatigans. The previous Brugia malayi foci, scattered over widely dispersed areas of the island, were apparently completely eliminated as a result of control of the Mansonia vectors by the destruction of the larval host plants in their swamp habitats. Control measures by the Anti-Filariasis Campaign against W. bancrofti and C. p. fatigans have greatly reduced the human infection rates in the endemic coastal belt and have kept the rate in the dense population to less than 1% over the last several years. This paper assesses the entomological aspects of the control programme during the years 1970-72.
