Lactobacillus jensenii, Lactobacillus crispatus, Lactobacillus iners, Lactobacillus gasseri and Lactobacillus vaginalis were identified by 16S rRNA gene sequencing as the predominant culturable vaginal Lactobacillus species in a group of South African women, comprising 24, 22, 10, 10 and 9 %, respectively. A significant effect of vaginal discharge syndrome (VDS) and bacterial vaginosis (BV) on the distribution of predominant Lactobacillus species was observed. Whilst L. crispatus isolates were almost equally distributed between individuals with and without VDS and were not significantly reduced in women with BV versus normal microflora, L. jensenii isolates were significantly reduced in women with VDS (P=0.022) and reduced in women with BV versus normal microflora (P=0.053). Unlike L. crispatus, L. jensenii isolates were also significantly reduced in women with BV-associated VDS versus women without VDS and with normal microflora (P=0.051). In addition, lysogeny was commonly observed for L. crispatus, with 77 % of isolates yielding phage particles with contractile and non-contractile tails. Only 29 % of L. jensenii isolates yielded phage particles, and these were visible as tailless or podo-like particles.
