Ces trypanosomes peuvent être inoculés dans les souris et les rats et il est suggéré que, dans certaines conditions, elles ou d'autres vivant dans l'intestin de l'insecte peut causer la maladie chez l'homme.

. Animal parasites and human disease. Insect Vectors; Parasites; Parasitic Diseases; Medical parasitology; Insects as carriers of disease. 382 BEDBUGS AND THEIR ALLIES of this bug have been found to contain trypanosomes in all phases of development, and of very variable form, possibly representing several species. These trypanosomes can be inoculated into mice and rats and it is suggested that under certain conditions they or others living in the gut of the bug may cause disease in man. A number of cases are on record where irregular fevers have followed the bites of this insect. Since these fevers were shown to be non-malarial and showed symptoms of typical trypanosome infection, it is possible that such an infec- tion may really be transmitted to man by this bug as well as by its close relatives in South America. It is also possible that the bug may serve as an intermediate host for the kala-azar parasite. Other Species. — Several other species of bugs of this family occur in Africa. One, Acanthaspis sulcipes, has been thought to be the possible transmitter of a form of endemic goitre in tropical Africa. In North America the family is further repre- sented by the " kissing bugs, " of the genus Melanolestes. The common kissing bug or " black corsair, " M. picipes, became very abundant in the United States a few years ago and gave op- portunity for many startling newspaper stories. It is a large black bug with reddish marks on the back and legs. Its bite much resembles that of a wasp, though often much more serious, occasioning more than local symptoms and even vomiting. Allied bugs of the genera Reduvius, Rasahus and Melanolestes occur in the warm parts of North and Central America, and frequently attack man and other mammals, though their normal food in most cases is insects. In Venezuela and other parts of northern South America a very common bug which in- fests houses is Rhodnius prolixus, a species which has been found capable of transmittin
