Chronic endocarditis due to Legionella anisa: a first case difficult to diagnose
نویسندگان
چکیده
Endocarditis due to Legionella spp. is uncommon but presumably underestimated given the prevalence of Legionellae in the environment. We report a first and unusual case of chronic native valve endocarditis due to L. anisa and advocate that the diagnosis of endocarditis be made collaboratively between the cardiologist, surgeon, microbiologist and pathologist.

Legionella anisa, a possible indicator of water contamination by Legionella pneumophila.
Legionella anisa is one of the most frequent species of Legionella other than Legionella pneumophila in the environment and may be hospital acquired in rare cases. We found that L. anisa may mask water contamination by L. pneumophila, suggesting that there is a risk of L. pneumophila infection in immunocompromised patients if water is found to be contaminated with Legionella species other than ...

متن کاملInfection of Tetrahymena pyriformis by Legionella longbeachae and other Legionella species found in potting mixes.
All Legionella longbeachae strains, both serogroups of L. bozemanii, and three strains of L. anisa reproducibly infected washed Tetrahymena pyriformis at 30 degrees C. L. pneumophila serogroup 1 strains infected T. pyriformis less reproducibly than did L. longbeachae. Low-level concentrations of nutrients in cocultures inhibited infection. Four L. micdadei strains and L. anisa ATCC 35292 failed...
