Compassionate Nitric Oxide adjuvant treatment of persistent. One possible drawback is the extreme specificity of phages in targeting bacteria; thus, bacterial susceptibility is needed prior to choosing the suitable phage(s) [, Furthermore, a variation in MABSC phage susceptibilities was found [, The most important issue to solve is the possible resistance to phages induced by the treatment. Currently, there have been few reported cases of phage therapy in humans, e.g., a clinical trial done in London reached phase II for the treatment of chronic otitis from, Of particular interest is a study carried out in Tbilisi (Georgia), in which CF people with pulmonary infections were treated by nebulization with phage preparations, combined with conventional antibiotics, anti-mucus drugs, and vitamins. CFTR is a type of protein classified as an ABC (ATP-binding cassette) transporter or traffic ATPase.
