High-level beta-lactamase activity in sputum samples from cystic fibrosis patients during antipseudomonal treatment.
The in vivo activity and source of beta-lactamase in sputum samples from 43 patients with cystic fibrosis (CF) during a 2-week antipseudomonal treatment were studied. A colorimetric method, based on the conversion of nitrocefin, was used for quantitation of the sputum beta-lactamase activity. beta-Lactamases in sputum were characterized by isoelectric focusing and inhibition profile and were co...
متن کاملMucus, phlegm, and sputum in cystic fibrosis.
Although some clinicians still believe that cystic fibrosis (CF) lung disease is largely due to hypersecretion of very viscous mucus, it has never been demonstrated that there is mucus hypersecretion in CF and it is clear that there is almost no intact mucin (the principal polymeric component of normal mucus) in CF sputum. CF sputum has lower viscosity when compared to asthma or bronchitis sput...
متن کاملElevated expression of both mRNA and protein levels of IL-17A in sputum of stable Cystic Fibrosis patients
BACKGROUND T helper 17 (Th17) cells can recruit neutrophils to inflammatory sites through production of IL-17, which induces chemokine release. IL-23 is an important inducer of IL-17 and IL-22 production. Our aim was to study the role of Th17 cells in cystic fibrosis (CF) lung disease by measuring IL-17 protein and mRNA levels and IL-22 and IL-23 mRNA in sputum of clinically stable CF patients ...
متن کاملIsolation of Staphylococcus aureus from sputum in cystic fibrosis.
The success in the isolation of Staphylococcus aureus of different methods of sputum processing was investigated in 60 specimens collected from 14 patients with cystic fibrosis during a seven-month period. Fifty specimens (83%) from 11 patients yielded Staph. aureus by one or more methods. Direct plating of purulent portions of sputum on to media designed for general use in respiratory infectio...
متن کاملConformity of bacterial growth in sputum and contamination free endobronchial samples in patients with cystic fibrosis.
The use of sputum cultures to guide the antimicrobial treatment of patients with cystic fibrosis has been questioned. Bacterial growth and antibiotic susceptibility patterns of 33 culture pairs from sputum and contamination free endobronchial swabs from 14 patients with cystic fibrosis were compared. As expected, Pseudomonas aeruginosa of the mucoid and non-mucoid type, Staphylococcus aureus, a...
