Figure 1From: Genetic loci of Mycoplasma agalactiae involved in systemic spreading during experimental intramammary infection of sheep Growth analysis of selected transposon mutants during co-cultivation with HeLa cells. Doubling time, in presence of HeLa cells 48 h pi, of the wild type strain PG2 and transposon mutants deficient in systemic spreading is shown. Each bar represents the average doubling time ± standard deviation of three independent experiments done in duplicates. *p < 0.05; **p < 0.005.Back to article page
