On day 14 after sampling, 2 of 3 anaerobic blood cultures (automated blood culture BACTEC 9240 system (Becton Dickinson, Le Pont de Claix, France) yielded a slow-growing, gram-negative microbe. Blood was subcultured onto Columbia agar with 5% sheep blood (Mérieux, Marcy l'Etoile, France) under 5% CO 2 and anaerobic atmosphere and resulted in small colonies. This slowgrowing microbe was lost after 2 subcultures, and no isolate is available for further description. The isolate retrieved in the blood culture was identified by 16S rRNA gene sequence analysis. The template DNA was prepared from a few colonies that were isolated on the blood agar incubated anaerobically. DNA was extracted by using Fastprep DNA extraction kit (Ozyme, St Quentin en Yvelines, France) according to the manufacturer's recommendations and was subjected to polymerase chain reaction (PCR) targeting the 16S rRNA gene as previously described (2) . Sequencing the PCR product (2) showed a 1,531-nucleotide sequence. This sequence shared 100% homology with that of V. montpellierensis (GenBank accession no. AY244769) and was already reported (GenBank accession no. AY244769) in a previous article (3) . In this article, the isolated Veillonella strain (that was isolated from our patient) was first identified as "candidatus V. atypica" since the sequencing of the amplicon disclosed 94% sequence similarity with that of V. atypica (3). V. montpellierensis had not yet been described. PCR contamination was unlikely since this organism had never been amplified in our laboratory and negative controls remained negative.
