Effect of VR1 CFS in delaying the cytotoxicity caused by A. veronii. Time lapse microscopic studies were carried out until 10 h incubation of Vero cells with different treatments of culture supernatant of A. veronii and VR1 in 1:10 ratio. We show here the representative images from the treatment of a) control b) A. veronii c) VR1 d) pre-incubation of VR1 for 6 h and then addition of A. veronii e) co-incubation of VR1 and A. veronii. Images a1-a5 represents the incubation time of 2, 4, 6, 8 and 10 h, respectively. Same denomination is followed for other treatments as well. Detachment of Vero cells can be observed from 6 h onwards in A. veronii treated cells. Arrow indicates cell detachment.
