This bacteria is a common cause of meningitis in both immunosuppressed people and neonates, which is why pregnant women are advised to avoid eating soft cheeses and drinking unpasteurized milk.
The entry of this pathogen into hepatocytes requires the inIAB operon. This pathogen's virulence genes are silent at 30 degrees Celsius, but once the temperature hits 37, the hairpin structure of PrfA melts and expression of genes such as Hly begins. This pathogen is instilled in a rabbit or guinea pig, resulting in severe keratoconjunctivitis, in a positive Anton test. This is the only Gram-positive bacteria whose lipopolysaccharides contain endotoxin. This bacteria uses extensive (*) "rocket" actin polymerization to move through eukaryotic cells, and displays a "tumbling motility" when viewed under a light microscope. This bacteria is a common cause of meningitis in both immunosuppressed people and neonates, which is why pregnant women are advised to avoid eating soft cheeses and drinking unpasteurized milk. For 10 points, identify this bacteria, with species name monocytogenes, named for the Englishman who pioneered sterile surgery.
