New microbiota found in sputum from patients with community-acquired pneumonia. Thirty patients recovered with initial antibiotic treatment (antibiotic success or AS), while 11 patients showed poor outcome (antibiotic failure or AF). Thank you for your interest in spreading the word about bioRxiv. | Sputum specimens collected from patients for molecular diagnostic testing frequently contain mucoid or mucopurulent material that make the specimen too viscous for efficient processing for downstream nucleic acid extraction. ; Johnson, E.J.

We have an interest in a specific bacteriophage, or a virus that infects bacteria. Other pathogens can be detected in sputum as well, including HIV. extraction methods (chloroform and GuSCN-silica methods), the stored sediments from inhibitory sputum samples were thawed and divided into equal aliquots and were processed by the two extraction methods separately.

Successful elimination of bacterial DNA was shown to be a critical step in the optimization process. The final evaluation consisted of the microbiota analysis of all the possible final conditions in order to have a general overview of the method. 0000020884 00000 n The lung tissue microbiota of mild and moderate chronic obstructive pulmonary disease. DNA/RNA extraction from sputum - (Feb/09/2010 ) Is there any standard protocol for DNA/RNA extraction for sputum which is viscous? There was significantly decreased alpha diversity and increased relative abundances of Pseudomonas, Achromobacter, Stenotrophomonas and Ralstonia in AF patients.

A sputum specimen is the name given to the mucus which is expectorated from the lower airways. ; investigation, S.A., L.T. DNA extraction from sputum protocol (method) by Laszlo Irinyi The present study had three objectives: (1) to evaluate the performance of DTT treatment to homogenize sputum samples; (2) to evaluate the effect of an enzymatic step for Gram-positive lysis; and (3) to investigate the performance of lytic chemical/enzyme-based and bead-based extraction kits. There are many different ways to process sputum depending on what aspect of the sputum is to be studied. Lancet 381, 1405–1416 (2013). We sought to find the best method to take sputum from a CF patient and extract DNA so that we could detect both bacteria and bacteriophage DNA. ; Suarez-Cuartin, G.; Sibila, O.; Furrie, E.; Fong, C.J. Lim, M.Y. Our results should facilitate future gene-expression studies utilizing sputum. We established a nucleic acid co-extraction method from sputum based on magnetic beads and optimized the method by evaluating influencing factors, such as the guanidinium thiocyanate (GTC) and dithiothreitol (DTT) concentrations, … Clinical measures of disease in adult non-CF bronchiectasis correlate with airway microbiota composition. 18 0 obj <> endobj xref 18 35 0000000016 00000 n
