Surveillance of avian influenza virus in migratory water birds in eastern Hokkaido, Japan.

The epidemiological information has obtained on avian influenza virus (AIV) in eastern Hokkaido, Japan, where AIV surveillance has not been performed. Cloacal or fecal samples obtained from migratory water birds were screened for AIV both by real-time reverse transcriptase polymerase chain reaction to detect the influenza A virus matrix (M) gene and by egg inoculation. Between 2007 and 2009, a ...

Prevalence and risk factor analysis of bovine hemoplasma infection by direct PCR in Eastern Hokkaido, Japan.

The prevalence and risk factors of 2 bovine hemoplasma species-Mycoplasma wenyonii (Mw) and "Candidatus Mycoplasma haemobos" (CMh)-were examined by direct PCR using whole blood samples collected from 343 cattle in Eastern Hokkaido, Japan. The sensitivity of the direct PCR assay was 10-fold higher than the standard PCR assay, detecting 5 copies of bovine hemoplasma DNA per reaction. An epidemiol...

Azole susceptibility in clinical and environmental isolates of Aspergillus fumigatus from eastern Hokkaido, Japan.

Azole antifungals are used not only clinically for fungal infections but also used as agricultural fungicides. Recently, azole-resistant Aspergillus fumigatus containing a tandem repeat in the promoter region of cyp51A combined with amino acid substitution(s) appears in the environment in Eurasia, especially in several European countries. Although azole fungicides have been used in Japan, espec...

Macrozooplankton and Micronekton off Hokkaido Island, Japan: Composition and Gear Inter-calibration

The second micronekton inter-calibration experiment (MIE-2) was carried out in the coastal area off southeastern Hokkaido Island, Japan, during September 23–October 3, 2005. Comparative tows were made at four stations situated over the upper continental slope with bottom depths of approximately 500 m (Fig. 3.1). This area is strongly influenced by the coastal branch of the Oyashio Current (Kono...
