Detection of antibodies in blood meals of hematophagous Diptera.

Antibodies are detectable by an agglutination technique in the blood meals of hematophagous Diptera that are fed on laboratory and domestic animals infected with organisms of the Trypanosoma brucei subgroup. It is likely that both the antibody status and the identity of the animal fed on can be determined from the same blood meal from wild Diptera. The technique may be applicable to other infections for which sensitive serological tests are available.

The dissemination of 17D yellow fever vaccine in Africans in Kenya in relation to the interpretation of results of protection-test surveys.

The extent of dissemination of 17D yellow fever vaccine among the population of Kenya, especially among Africans, is estimated, largely from information in the records of the Kenya Medical Department. The total recorded vaccinations of Africans between 1941 and 1951 amount to about 379,000, representing 7.2% of the African population in 1948; it is, however, possible that the actual number of vaccinations is considerably higher. At Mombasa, 78,000 persons of races other than Africans were given routine inoculation over the same period.After a study of the economy of use of vaccine, the author discusses the protection-test surveys performed before 1951 and during that year in relation to the dissemination of vaccine. It is tentatively concluded that natural infection of man with yellow fever is rare in both Kenya and Tanganyika.
