Bordetella parapertussis evolved in a host population that had already developed immunity to "B. pertussis", where being able to evade "B. pertussis" immunity was an advantage. Two lineages of "B. parapertussis" have been described. The first infects humans and is responsible for a minority of cases of the disease pertussis (also known as whooping cough). The second, ovine, lineage causes chronic nonprogressive pneumonia in sheep. Both lineages are thought to have evolved from a "B. bronchiseptica"-like ancestor. This disease can be symptomatic or asymptomatic and may predispose hosts to secondary infection. Bordetella parapertussis Bordetella parapertussis is a small Gram-negative bacterium of the
Coronary artery disease of adult stem cell populations. Research is still going on – with first promising results particularly for FGF-1 and utilization of endothelial progenitor cells. Myeloperoxidase has been proposed as a biomarker. Dietary changes can decrease coronary artery disease. For example, data supports benefit from a plant-based diet and aggressive lipid lowering to improve heart disease. Coronary artery disease Coronary artery disease (CAD), also known as ischemic heart disease (IHD), is the most common of the cardiovascular diseases. Types include stable angina, unstable angina, myocardial infarction, and sudden cardiac death. A common symptom is chest pain or discomfort which may travel
