<i>In vitro</i> studies of <i>Rickettsia</i>-host cell interactions: Confocal laser scanning microscopy of <i>Rickettsia helvetica</i>-infected eukaryotic cell lines - Fig 1

<p><b>Growth of <i>Rickettsia helvetica</i> AS819 in Vero E6 (A) and L929 (B) cell cultures.</b> Genome equivalents measured by quantitative <i>gltA</i> PCR of infected cell cultures are given at several time points during infection. The values from triplicate infected cultures were averaged; standard deviation error bars are given. Growth studies using Vero E6 (A) and L929 (B) were performed simultaneously. ● indicate <i>gltA</i>-copies/μl template-DNA purified from cell layers, and ■ represent <i>gltA</i>-copies/μl template-DNA obtained from culture supernatants.
