Wolbachia contribute to metabolic activity as measured by the MTT reduction assay C6/36 and C6/36 Wp were incubated in medium or medium with tetracycline 20 μg/ml for four weeks before the MTT reduction assay was performed. Bars represent means of five repeats each of 250 000 cells (± S.D.). Values that are significantly lower than those of C6/36 Wp are denoted by * (P = 0.000) and ** (P = 0.03).
