The water and ionic permeability induced by polyene antibiotics across plasma membrane vesicles from Leishmania sp.


An osmotic method has been used to study the effect of the polyene antibiotics amphotericin B, nystatin and candicidin on the water permeability of plasma membranes prepared from Leishmania sp. The effect of amphotericin B on the permeability of Leishmania membranes to a salt such as potassium nitrate was also investigated. A non-linear and saturable… (More)
