WYEOMYIA SUBGROUP OF ARBOVIRUS: ISOLATION FROM MAN.

An agent, serologically identical to a Wyeomyia virus obtained from mosquitoes, was isolated from a worker on the inter-American highway project in Darien Province in eastern Panama. He experienced a mild febrile illness with recovery. A significant rise in anttibody titer to this virus was demonstrated in his serum during convalescence. Neutralizing antibodies to this newly isolated strain were found in 10 of 59 blood samples from inhabitants of Darien Province. The virus is designated the Darien strain.

Serological evidence of infection of Tacaribe virus and arboviruses in Trinidadian bats.

Sera from 39 species of bats collected in Trinidad between 1972 and 1974 were tested against some or all of 18 arboviruses in hemagglutination inhibition (HI) and/or suckling mouse neutralization (N) tests. A few sera were HI-positive with Mucambo, eastern equine encephalitis (EEE), Oriboca, Restan, Manzanilla, Guama, Bimiti, and Catu. No sera were HI-positive with Mayaro, Caraparu or Maguari. Many ser inhibited one or more of the group B hemagglutinins: Ilheus, St. Louis encephalitis (SLE), dengue 2, and yellow fever (YF), positives occurred in nearly every species of bat, being most frequent with Ilheus. In N tests, a few or single sera were found to protect against Ilheus, Nepuyo, Guama, Bimiti, and Cocal, while none protected against EEE, SLE, YF or Catu. Many sera positive in HI test with Ilheus, SLE or YF failed to neutralize the respective virus. Tacaribe neutralizing antibody was demonstrated in Artibeus jamaicensis and A. lituratus, the sources of past virus isolation, in the fruit bats Sturnira lilium and Vampyrops helleri, and in the vampire bat Desmodus rotundus. Sera from 19 other species gave either negative or inconclusive results. No convincing evidence of Tacaribe antibody was found in 29 human sera, 20 from bat collectors.

STUDIES OF ARBOVIRUSES IN WESTERN AUSTRALIA. SEROLOGICAL EPIDEMIOLOGY.

In order to obtain information on the occurrence of arboviruses in Western Australia, sera from white persons and Australian aborigines and from animals were subjected to antibody estimations with selected viruses as a prelude to virus isolations. The serological evidence shows the presence of group A and group B arboviruses but significant differences in antibody distribution between the two groups. Antibodies to group A viruses, particularly to the Malayan mosquito virus AMM 2354, are present in both the aboriginal and the white populations over the entire territory. Neutralizing antibody to another group A virus, AMM 2021, isolated in Malaya, is found in much lower prevalence, while antibodies to the newly isolated Queensland group A virus, MRM 39, are found only in the Kimberley area. No avian group A antibodies were detected. The prevalence of group B antibodies is high in the northern part of the State and almost non-existent in the central areas. The results indicate the presence of more than one group B virus and the absence of dengue neutralizing antibody in the Australian aborigine. A unique situation exists in central Australia, where all aboriginal sera have group A antibody but none has group B antibody.
