title: The influence of lorry transport on the Trypanosoma vivax infection rate in Nigerian trade cattle.
abstract: In Nigeria in 1974 and 1975 there was an apparent sharp reduction in the prevalence of trypanosomiasis of cattle at several markets and control points. Some of the decrease appears to be due to the tsetse eradication programmes and Sahelian drought, but the change to lory transport as the principal means of moving cattle from the northern grazing areas to the south-western markets, which replaced a trek of at least three weeks, was probably an important factor.
