[, Therefore, being as this preliminary evidence very promising, it is advisable to continue to study the use of NO as an alternative strategy to treat, Phage therapy (PT) represents an old idea which has acquired renewed importance thanks to the successful recent case reports, where antibiotic-resistant lung infections in CF people were treated [, PT refers to the use of phages to fight bacterial infections. 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. How does cystic fibrosis affect the reproductive system? In CF, the inherited CF gene directs the body's epithelial cells to produce a defective form of a protein called.
