An extracellular particle approximately 40 nM in diameter was detected in culture supernatant from the fastidious bacterium Rochalimaea henselae. This particle has at least three associated proteins and contains 14 kbp linear DNA segments that are heterogeneous in sequence. The 14 kbp DNA was also present in R. henselae cells as an extrachromosomal element for all 14 strains tested. Despite attempts to induce lysis of R. henselae, plaque formation was not observed. A similar particle, also containing 14 kbp DNA, was observed in Bartonella bacilliformis, and may be analogous to a bacteriophage that has been described elsewhere for B. bacilliformis.
