Mass treatment with azithromycin is the mainstay of the WHO strategy for both the eradication of yaws and the elimination of trachoma as a public health problem , but the dose recommended for trachoma is lower than that for yaws . In countries where both diseases are ... | Yaws is a neglected tropical disease caused by a bacterium closely related to the agent of syphilis . Mass treatment is recommended by WHO for the control of both yaws and the blinding eye disease trachoma , but the dose used for trachoma is lower ( 20 mg/kg versus 30 mg/kg ) . We have previously shown that a single ro... | [

Merkel cell polyomavirus ( MCV or MCPyV ) is the first human polyomavirus to be definitively linked to cancer . The mechanisms of MCV-induced oncogenesis and much of MCV biology are largely unexplored .
