Quinine sulfate and bacterial invasion

Table 1 Invasion efficiency of E. coli HB101 pRI203 into HeLa cells in the presence of quinine sulfate (QS)

Inoculated and internalized viable bacteria were evaluated by counting them on agar plates. Invasive efficiency is the percent of the inoculated colony-forming units (CFU) which were internalized. Condition 1: QS was incubated with 3 × 10⁵ HeLa cells for 60 min at 37°C prior to infection; condition 2: QS was added to the HeLa cell monolayers during the infection period.
