Experimental Transmission of Yellow Fever by Central American Species of Haemagogus and Sabethes Chloropterus

Abstract

SummarySuccessful transmission from monkey to monkey of a strain of yellow fever virus isolated in Trinidad was obtained with the following Middle American Haemagogus: H. m. mesodentatus, H. m. gorgasi and H. equinus. All the above mentioned species as well as H. lucifer and H. spegazzinii falco were found by intracerebral mouse inoculation to harbor yellow fever virus from one to four weeks after the infective meal. No virus was isolated from mice injected with pools of S. chloropterus even though the species transmitted the virus by bite from monkey to monkey on one occasion.
