In A. aegypti, bacilli persisted in proboscis till 156 hours, in gut 96 hours, and in faeces 72 hours after feeding. In C. fatigans--proboscides 144 hours, gut 96 hours and faeces 72 hours after feeding. In A. aegypti solid bacilli were present in proboscis upto 96 hours; in gut 48 hours and in faeces 42 hours after feeding. Corresponding figures for C. fatigans were: 144 hours for proboscis, 48 hours for gut, solid bacilli being absent in faeces. The results are discussed from the point of view of arthropod transmission.</p>  a0024-1024
