PROGRESS OF VERRUGA WORK WITH PHLEBOTOMUS 



VERRUCARUM T. 



By Charles H. T. Townsend, Director of Enlomological Stations, Lima, Peru 



The following is a brief abstract of the results to date from inocu- 

 lations of laboratory animals with Phlehotomus verrucarum T. at the 

 Verruga Laboratory in Chosica (near Lima), Peru. The temperatures 

 given are all rectal and Centigrade. All weights are in grams. All 

 dates are 1913. 



It ma}' be said by way of preface that Dr. R. P. Strong, of Harvard, 

 assisted by others, has recently put forth the opinion that Barton's x- 

 bodies are the causative organism of Oroya fever, and has bestowed 

 on them the name Bartonia baciUiformis; that verruga eruption is 

 caused by a virus present in the eruption; and that the two are sepa- 

 rate pathologic entities. To this the writer of the present article does 

 not agree; but the rr-bodies in question, or what appear indistinguish- 

 able therefrom morphologically, are referred to herein as Bartonia 

 bodies. 



It is well to state that the Verruga Laboratory at Chosica is quite 

 outside the limits of the verruga zones, the nearest known verruga 

 locality being Santa Eulalia some three miles distant. The topog- 

 raphy of the country lying between Santa Eulalia and Chosica, the 

 unfailing strong winds in the Chosica valley, the heavy night fogs 

 during the cool season, and the lack of sufficient rainfall during the 

 warm season, all combine to preclude any chance of the disease reach-
