Western Steppe HerdersIn archaeogenetics, the term Western Steppe Herders (WSH), or Western Steppe Pastoralists, is the name given to a distinct ancestral component first identified in individuals from the Eneolithic steppe around the turn of the 5th millennium BC, subsequently detected in several genetically similar or directly related ancient populations including the Khvalynsk, Sredny Stog, and Yamnaya cultures, and found in substantial levels in contemporary European, West Asian and South Asian populations.
BuboA bubo (Greek βουβών, boubṓn, 'groin') is adenitis or inflammation of the lymph nodes and is an example of reactive lymphadenopathy. Buboes are a symptom of bubonic plague and occur as painful swellings in the thighs, neck, groin or armpits. They are caused by Yersinia pestis bacteria spreading from flea bites through the bloodstream to the lymph nodes, where the bacteria replicate, causing the nodes to swell. Plague buboes may turn black and necrotic, rotting away the surrounding tissue, or they may rupture, discharging large amounts of pus.
