Figure 5From: Reverse transcriptase-PCR differential display analysis of meningococcal transcripts during infection of human cells: Up-regulation of priA and its role in intracellular replicationMorphology of B1940 and B1940ΩpriA meningococci. Meningococcal strains B1940 and B1940ΩpriA were grown to late (1.0 OD600 nm) logarithmic phase and observed by scanning electron microscopy. Note that priA-inactivation does not affect the typical diplococcal, coffee bean-shaped morphology of meningococci.Back to article page
