Background:
Duration of digestion/decontamination has a considerable impact on yield of mycobacteria especially from sterile body fluids and pus specimens. Additionally, duration of digestion/decontamination affects the contamination rates. This study evaluates the effect of digestion/decontamination protocol for 15 and 20min versus inoculation of media directly from the sample on contamination rates as well as the yield of mycobacteria from pus and sterile fluids other than cerebrospinal fluids.
Methods:
Pleural fluid (n=60), pus (n=48) and ascitic fluid (n=12) specimens were cultured for mycobacteria and evaluated for contamination and mycobacterial yield using three different processing methodologies ...
