''Legionella jordanis'' is a Gram-negative bacterium from the genus ''Legionella'' which was isolated from the Jordan River in Bloomington, Indiana and from the sewage in DeKalb County, Georgia.〔〔〔〔 ''L. jordanis'' is a rare human pathogen and can cause respiratory tract infections.〔 ==History== ''Legionella jordanis'' strain BL-540 was first isolated from water samples taken at the Jordan River in Bloomington, Indiana by Cherry et al. in 1978.〔 Another strain characterized as ABB-9 was discovered in 1980 from sewage collected in DeKalb County, Georgia. The specific epithet ''jordanis'' was derived from the name of the river in which was discovered.〔 The two strains were both Gram-stained. They Sudan black B fat stain for lipids and the Wirtz-Conklin method were used to demonstrate spore formation. Acid-fast staining was used, as well. The cultures were streaked onto trypticase soy agar (TSA) and charcoal yeast extract (CYE) agar slants,〔 and were left to incubate around 36°C in candle extinction jars that remove oxygen from the jar by burning a candle with the lid tightly sealed. The cultures failed to grow on the TSA plates, but did show growth on CYE slants which Cherry et al. expected. They were removed at 24- and 48-hour periods and tested for oxidase and catalase production.〔
