Identification and phylogenetic analysis of oral Veillonella species isolated from the saliva of Japanese children

“…It was previously reported that a higher number of anaerobic bacteria was detected on BHI agar in saliva from Thai children with poor oral hygiene than those with good and moderate oral hygiene 20 . This prior study demonstrated that oral Veillonella isolates were detected at a twofold higher frequency in the saliva of Thai children with poor rather than good or moderate oral hygiene 20 . Here, it was demonstrated that the number of anaerobic bacteria on BHI agar and Veillonella species on the selective medium increased in saliva of Japanese children with worsening oral hygiene status.…”

“…Then, 1,442 of 1,609 strains were detected by the one-step PCR method with the species-specific primer sets for V. atypica , V. denticariosi , V. dispar , V. parvula , V. rogosae , or V. tobetsuensis. They reported that V. rogosae was the predominant species detected in all groups 20 . These results of the previous and present studies indicate that V. rogosae is the predominant oral Veillonella species in the human saliva and tongue biofilm.…”

“…A previous study also showed that V. rogosae was the predominant Veillonella species in tongue biofilms of the children in Thailand 12 . Recently, Theodorea et al isolated 1,609 Veillonella strains from saliva samples of Thai children divided into three groups: good, moderate and poor oral hygiene status 20 . Then, 1,442 of 1,609 strains were detected by the one-step PCR method with the species-specific primer sets for V. atypica , V. denticariosi , V. dispar , V. parvula , V. rogosae , or V. tobetsuensis.…”

“…To resolve this problem, Mashima et al established a novel one-step PCR method with species-specific primer sets based on the variable region of the rpoB gene sequences of oral Veillonella species 12 . Additionally, 1,442 Veillonella strains isolated from the saliva of 107 Thai children were identified by this method as V. dispar , V. parvula , V. rogosae , V. atypica , V. denticariosi , and V. tobetsuensis in our previous study 20 . In that study, V. parvula was significantly more prevalent in the poor oral hygiene, and the detection rate of oral Veillonella species in the saliva was indicative of the oral hygiene status of Thai children 20 .…”

“…Additionally, 1,442 Veillonella strains isolated from the saliva of 107 Thai children were identified by this method as V. dispar , V. parvula , V. rogosae , V. atypica , V. denticariosi , and V. tobetsuensis in our previous study 20 . In that study, V. parvula was significantly more prevalent in the poor oral hygiene, and the detection rate of oral Veillonella species in the saliva was indicative of the oral hygiene status of Thai children 20 . Additionally, another study suggested that several novel Veillonella species may inhabit the human oral cavity 21 .…”
