Effect of sodium polyanethol sulfonate in blood cultures
Abstract:
Fifteen-hundred hospital blood cultures were made in duplicate, with and without 0.05% sodium polyanethol sulfonate in the broth medium. A significantly higher rate and speed of recovery of both gram-positive cocci and gram-negative bacilli was accomplished in sodium polyanethol sulfonate broth. The effect was independent of the content of 0.1% agar in the growth medium. In the cases of Neisseria meningitidis septicemia examined, however, a detrimental result on recoveries was observed. The addition of sodium polyanethol sulfonate also resulted in an increased frequency of recoveries of contaminating organisms.

Sputum Studies II: Culture and Sensitivity
Sputum culture and sensitivity is a medical procedure used to diagnose bacterial infections in the respiratory tract and select the most appropriate antibiotics for treatment. This process involves analyzing sputum samples of thick and opaque secretions produced in the lungs and airways. These samples are collected from patients and then sent to the laboratory for analysis.
The test can identify various pathogens responsible for respiratory infections, including Streptococcus,...
