Fig. 3From: Antimicrobial and immunoregulatory effects of Lactobacillus delbrueckii 45E against genitourinary pathogensInverted microscopy was used to visualize the adhesion of LB on HeLa cells. A shows Ld45E (purple bacilli) on HeLa cells. The yellow arrows indicate a high quantity of Ld45E adhered onto HeLa cells. B Shows the control group HeLa cells incubated for 24 h at 37 °C in a 5% CO2 incubator. The black arrows indicate (purple cells) stained with crystal violate. C shows L. reuteri RC-14 (purple bacilli) on HeLa cells. The yellow arrows indicate a few L. reuteri RC-14 adhered onto HeLa cells (purple stain), magnification 40 × Back to article page
