Leprosy 



Currle, D. H. Studies on Leprosy. IX, Mosquitoes in relation to the trans- 

 mission of leprosy. X, Flies in relation to the transmission of leprosy. Pub. Health 

 & Mar. Hospt. Ser. Bull. 39, Sept., 1910. The reason that mosquitoes that have 

 fed on lepers do not contain the lepra bacilli is that when these insects feed they 

 insert their proboscis into a blood vessel and thus obtain bacilli-free blood un- 

 mixed with lymph. This fact accounts for the absence of lepra bacilli in mosqui- 

 toes, which are therefore not to be regarded as carriers of the disease. Flies feed 

 on leprous fluids and contain the bacilli in their intestinal tract and feces for several 

 days and may convey them directly or indirectly to the skins, nasal mucosa, and 

 digestive tracts of healthy persons. Fhes are therefore to be regarded as one of the 

 possible means of disseminating leprosy. 



House Fly 



Bertarelli, E. Flies and typhus fever. Centralbl. Bakt. Parasitenk. Vol. 53 

 (1910), p. 486-495. Submits experimental evidence to show that house flies may 

 serve as disseminators of typhus fever. 



Byer, H. G. Dissemination of disease by the fly. N. Y. Med. Jour., April 2, 1910, 

 considers flies as possible etiological factors in tuberculosis, leprosy, cholera, plague, 

 summer diarrhea of children, tj^phoid and other diseases.

 Notes on several species. 



Converse, G. M. Amoebiasis. Bull. Cal. St. Bd. Health, October, 1910. Points 

 out the possibility of flies feeding on stools from infected persons then fljing to 

 the food of others and thus carrying the amoeba that cause the disease.
