Although genetic variations at these loci have long been considered neutral, the availability of a significant amount of epidemiological data and the use of mathematical models have allowed us to discover that some combinations of alleles at these loci may be subject to selection and that some combinations in some hypervirulent lines are associated with small gains in fitness for meningococcal transmission (Buckee et al., 2008)

Red or purple chromaturia is a side effect of hydroxocobalamin, typically resolving over several weeks.2 Additional causes of red urine include blood (e.g., traumatic catheterization, malignancy, infection), dietary ingestion (e.g., beets), and medications (e.g., rifampin, phenothiazines).3 Although benign and not warranting further evaluation by itself, hydroxocobalamin-induced discolouration of body fluids may interfere with colorimetric sensors
