A 7-year-old girl was admitted to the hospital with acute
lymphoblastic leukemia and was treated with allogenic cord blood transplantation. At day 30 after graft, she developed a fever and
multiple nodular lesions disseminated in the liver and lungs. All
bacterial cultures attempted on liver and lung biopsy specimens and
blood remained sterile on standard axenic media. However, inoculation
of liver and lung biopsy specimens on eukaryotic cell monolayers by the
centrifugation-shell vial technique (M. Marrero and D. Raoult, Am.
J. Trop. Med. Hyg. 40:197-199, 1989) led to the recovery of a strain
of Legionella pneumophila serogroup 1, identified by 16S
rRNA gene amplification and sequencing and serotyping. Our findings
demonstrate that the centrifugation-cell culture method, which has
previously been useful for the isolation of other strictly or
facultatively intracellular bacteria, can also serve as a method for
the recovery of L. pneumophila from clinical material.
