Two types of tests, using mosquitoes as vectors, were employed. One type involved the feedings of mosquitoes on previously inoculated birds, then after a period of from zero to ninety-six hours refeeding the mosquitoes on assay birds. The second type of insect test comprised the feeding of mosquitoes on inoculated birds, then macerating and inoculating them into check birds at intervals of one to twenty-one days following feeding. Other experiments were conducted in which uninoculated birds were brought into close contact with inoculated chickens and their excrement. The observation of all tests indicated the absence of transmission of an infective titer of the infectious synovitis agent. These conclusions are drawn from tests using Aedes aegypti (Linn.) and Culex fatigans Wied., with methods and materials described.60 leavesBTDapplication/pdfenIn CopyrightLD5655.V855 1961.P473Mosquitoes as carriers of diseaseMycoplasma diseases in animals -- TransmissionPoultry -- Diseases -- TransmissionThesishttp://scholar.lib.vt.edu/theses/available/etd-10032008-063050/
