Enhancement of recovery of Neisseria meningitidis by gelatin in blood culture media.
نویسندگان
چکیده
The efficacy of gelatin for the recovery of Neisseria meningitidis from blood cultures was evaluated in a clinical setting. The organism was isolated from seven patients with meningococcal infections in blood culture media containing 1% gelatin. In contrast, only two blood cultures from these patients were positive in media without gelatin (P less than 0.05). Gelatin did not influence the recovery of other organisms isolated during this study. Conventional blood culture media may be supplemented with gelatin when meningococcemia is suspected.

Effect of sodium polyanetholesulfonate and gelatin on the recovery of Gardnerella vaginalis from blood culture media.
Sodium polyanetholesulfonate (SPS) is used as a routine supplement to blood culture media to enhance recovery of microorganisms, but it inhibits the growth of Peptostreptococcus anaerobius, Neisseria meningitidis, Neisseria gonorrhoeae, and Streptobacillus moniliformis. Comparative clinical blood culture studies at the University of Colorado Hospital suggested that SPS also inhibits the growth ...
متن کاملGelatin neutralization of the inhibitory effect of sodium polyanethol sulfonate on Neisseria meningitidis in blood culture media.
The inhibitory effect of sodium polyanethol sulfonate (0.05%) upon growth of Neisseria meningitidis was found to be neutralized by adding gelatin (l.1%) to the growth medium. The neutralizing effect was demonstrated in solid medium, as well as in nutrient broth for blood cultures. The findings parallel those of Wilkins and West (6) regarding gelatin neutralization of the inhibitory effect of so...
متن کاملControlled evaluation of blood culture medium containing gelatin and V-factor-analog for detection of septicemia in children.
Both Neisseria meningitidis and Haemophilus influenzae are important isolates recovered in blood cultures from septicemic children. Sodium polyanetholsulfonate is present in most blood culture media and can inhibit the growth of certain bacteria, including N. meningitidis. The addition of gelatin to blood culture media neutralizes this inhibition. The growth of H. influenzae is enhanced by spec...

Tests of 25 strains of Neisseria meningitidis for sensitivity to sodium polyanethol sulfonate (SPS) showed that the sensitivity of strains varied with both inoculum size and SPS concentration. In Trypticase soy broth (TSB), 2 out of 13 strains were sensitive to 0.05% SPS, whereas 8 out of 13 strains were sensitive to the same concentration of SPS in brain heart infusion (BHI). In artificial blo...
