Ecological and Physiological Factors in the Cyclic Transmission of African Trypanosomiasis

  • F. L. Lambrecht


The cyclic transmission of African trypanosomes is subject to the successful passage through successive ‘biological barriers’ associated with the ecology and physiology of the host(s) and vector(s), and the ability of the parasite to adjust to the various substrates. This paper is an analytical compilation of factors which play a relevant role in the complex pathway characteristic of trypanosome transmission. These are discussed under the following headings: (a) physiology of the parasite; (b) physiology of the vector; (c) ecology of the vector; (d) feeding habits of the vector; (e) physiology of the vertebrate host; and (f) behaviour of the vertebrate host.
