Light micrograph (phase contrast) of Lactobacillus bulgaricus bacteria,taken from live yoghurt. The relatively long,Gram-positive bacteria appear as thin,black rods. They are commonly found among the normal human internal flora in places such as the stomach,gut,mouth & vagina. Lactobacillus produces lactic acid from the fermentation of carbohydrates. This acidic environment,notably in the vagina,protects the host by inhibiting the growth & replication of other more pathogenic bacteria. Magnification: x400 at 35mm size | |
