A brief literature résumé of the hereditary transmission of human infections by arthropods is presented. This mechanism of transmission is of considerable importance in the epidemiology of these diseases and in a few instances is probably the normal method by which the parasite reaches man. It is also of great significance in the propagation and maintenance among animal reservoirs. Attention is called to the occasional presence of microörganisms within the ova of mosquitoes. While as yet there is no experimental proof that the etiological agent of any human infection may be hereditarily passed through the mosquito, additional research may force us to change our opinions on this subject.
