| characteristics of legionella pneumophila serogroup 2 strains by colony morphology. | the isolation rate of legionella pneumophila serogroup 2 from clinical samples is low. in 2007, we encountered the second case known to occur in japan. as the l. pneumophila serogroup 2 type strain, the kobe strain isolated in 1988, and the okinawa strain isolated from the present patient could not be differentiated using the usual biochemical and serological tests, we tried to achieve differentiation by observing colony morphology. in oxoid bcyealpha medium, colonies of the kobe strain develope ... | 2008 | 19050363 |
