| epidemiological survey of babesia species in japan performed with specimens from ticks collected from dogs and detection of new babesia dna closely related to babesia odocoilei and babesia divergens dna. | detection and analysis of babesia species from ticks recovered from dogs in japan were attempted by pcr and nucleotide sequence analysis based on the 18s rrna gene, respectively. a total of 1136 ticks were examined for babesia dna by 18s rrna-based pcr and nucleotide sequencing. partial sequences of babesia canis vogeli dna were detected from six ticks in aomori, nara, hiroshima, oita, and okinawa prefectures; and babesia gibsoni asia-1 dna was also detected in four ticks in osaka, hiroshima, mi ... | 2003 | 12904344 |
| frequency of amantadine-resistant influenza a virus isolated from 2001-02 to 2004-05 in nara prefecture. | we investigated the frequency of amantadine-resistant influenza a viruses in nara prefecture during four epidemic seasons from 2001-02 to 2004-05. point mutations within the m2 gene were identified using rt-pcr and dna sequencing analysis. five viruses (3.4%) with point mutation were observed from 145 strains analyzed. three viruses (2.0%) possessed a change at position 31 (agt-->aat, ser to asn), one virus (0.7%) showed a change at position 26 (ctt-->ttt, leu to phe), one virus (0.7%) showed a ... | 2006 | 16785705 |
