Summary: | Introduction : Streptococcus pyogenes (Grup A Streptococcus) is one of the major
pathogens causing from mild to severe infection. Antibiotic is a main therapy of
Streptococcus infection. The patient's disobedience in the treatment series will
results in inadequate medical treatments and potent to increase of the post
streptococcal infection sequelae. Red Ginger (Zingiber officinale Roscoe) is known
to contain monoterpenoid compounds (eg linalool) that have antibacterial
properties. This research was conducted to investigate the antimicrobial activity of
essential oil of red ginger against Streptococcus pyogenes.
Method : This research was a true experimental with post-test controlled group
design and was done in the laboratory of microbiology. Rhizome of red ginger was
destilated using steam distillation method and the growth of Streptococcus
pyogenes was measured using the dilution method to determine the Minimum
Inhibitory Concentration (MIC) and Minimum Bactericidal Concentration (MBC).
The extract concentration used in this research were 4,8%, 2,4%, 1,2%, 0,6%, 0,3%,
0,15%, 0,075 %, 0,0375%, 0,01875%, 0,009375%, and 0,0046875%. This
experiment was replicated three times. MIC was observed by the significant
alterations of solution’s turbidity after incubation at 37oC for 24 hours. All those
solutions then cultured on blood agar plate at 37oC for 24 hours and observed
visually by noticing the growth of bacterial colonies.
Results :MIC could not be determined due to no significant alterations in turbidity.
Cultures on blood agar plate shows mean or average of MBC was 0,7%.
Conclusion : In summary, essential oil of red ginger has antimicrobial effect
against Streptococcus pyogenes. |
