FIG. 3.
Cellular integrity of RAW 264.7 cells infected with B. pseudomallei. Monolayers were infected with B. pseudomallei DD503 (•) or ZP1220 (○) at an MOI of 10. The percent cytotoxicity was determined by assaying for LDH release in culture supernatants at 6, 12, and 18 h postinfection. The values are the means ± standard deviations of three independent experiments performed in duplicate.
