Abstract:
During the past two years, we have carried out the following studiesl Ultrastructural study of Rift Valley fever RVF virions in the cardia. 2 Immunocytochemical studies of the salivary glands and other tissues in Anopheles sp. which had been shown to be non-transmitters when intrathoracically-infected as adults, but transmitters when infected as immatures. 3 Immunocytochemical study of Ockelbo virus in Culex pipiens. 4 Ultrastructural examination of various tissues for RVF virus in hemocoelically- infected Cx. pipiens. 5 Development of an immunogold procedure for in situ labelling of RVF virions in electron microscopic preps. 6 Worked toward the identification and isolation of the mosquito cell surface receptor molecule for RVF virus. 7 Developed and presented a pre-meeting workshop, Mosquito Histology, Ultrastructure, and Methods for In situ Localization of Viruses, held in conjunction with the annual meeting of the American Society of Tropical Medicine and Hygiene. 8 Made progress in the development of a monograph on mosquito histology and ultrastructure.
