A existência de tais bacilos persistentes (ou dormentes) após a quimioterapia foi demonstrada logo após a introdução da isoniazida. O termo persistência refere-se à capacidade dos bacilos tuberculosos de sobreviverem na presença de concentrações bactericidas de quimioterápi-cos durante tratamentos conduzidos corretamente.Pouco se conhece sobre o que lev… Show more
