Investigation of Growth of Microorganisms within the Spacers of Children with Cystic Fibrosis

Background and aim: Cystic fibrosis is a monogenic disorder in several systems. Since spacers used by these patients may be used several times a day, many of them do not know how to wash and use them, so these devices are good places for bacteria to grow. Therefore, this study was performed to identify and determine the relationship between the growth of microorganisms inside spacers and the ef...
