Five species of myrmecophilous microdispid mites (Acari: Microdispidae) are recorded from Western Siberia, Russia. Unguidispuslasii Kurosa, 1979, Unguidispusjaponicus Kurosa, 1979, Caesarodispusminutus (Sevastianov, 1981), and Caesarodispussamsinaki (Mahunka, 1967), comb. n. are reported from Russia for the first time. Unguidispuspolyctenus (Sevastianov, 1969) and Caesarodispussamsinaki are red...

Powassan virus is endemic to the United States, Canada, and the Russian Far East. We report serologic evidence of circulation of this virus in Alaska, New Mexico, and Siberia. These data support further studies of viral ecology in rapidly changing Arctic environments.

Of 235 Mycobacterium tuberculosis isolates from patients who had not received tuberculosis treatment in the Irkutsk oblast and the Sakha Republic (Yakutia), eastern Siberia, 61 (26%) were multidrug resistant. A novel strain, S 256, clustered among these isolates and carried eis-related kanamycin resistance, indicating a need for locally informed diagnosis and treatment strategies.

A new species of the genus Paravillersia Kuznetsov, 1978 (Acari: Stigmaeidae), P. jamaliensis Khaustov sp. nov. is described from mosses on fen in Western Siberia, Russia. The supplementary description of Paravillersia grata Kuznetsov, 1978 is provided based on the type material. 

Genetic analyses of highly pathogenic avian influenza A(H5N8) virus from the Netherlands, and comparison with strains from Europe, South Korea, and Japan, showed a close relation. Data suggest the strains were probably carried to the Netherlands by migratory wild birds from Asia, possibly through overlapping flyways and common breeding sites in Siberia.

Ixodes persulcatus (n = 125) and Dermacentor reticulatus (n = 84) ticks from Western Siberia, Russia, were tested for infection with Borrelia, Anaplasma/Ehrlichia, Bartonella, and Babesia spp. by using nested polymerase chain reaction assays with subsequent sequencing. I. persulcatus ticks were infected with Borrelia burgdorferi sensu lato (37.6% +/- 4.3% [standard deviation]), Anaplasma phagoc...
