Introduction:
The onset and maintenance of disease can be significantly influenced by the colonization of the mouth cavity by pathogenic microorganisms or by an imbalance of the physiological microbiome. Hence, in the current study, various commonly used antibiotics have been tested for their antibacterial and antifungal activity.
Materials And Methods:
The current research was performed as an in vitro study. The commonly used antibiotics Augmentin (CV), Ceftriaxone-Cephalosporin (CF), and Linezolid were tested for the microorganisms, lactobacillus, and Escherichia coli. The "Radius of Zone of Inhibition (mm)- RZI" after 24 and 48 h were tested by the agar-well diffusion method.
Results:
For E. coli, the antibiotics tested were CV (5 μl and 2.5 μl), CF (5 μl and 2.5 μl), and Linezolid (5 μl and 2.5 μl). The results showed that the radius of the zone of inhibition was consistent for each antibiotic concentration, with a range of 0.8-1.4 mm at both time points. For Lactobacillus, the antibiotics tested were CV (5 μl and 2.5 μl), CF (5 μl and 2.5 μl), and Linezolid (5 μl and 2.5 μl). The results showed that the radius of the zone of inhibition varied between antibiotics and concentrations, with a range of 0.5-1.8 mm at both time points.
Conclusion:
This study highlights antibiotics' antibacterial action against E. coli and Lactobacillus. The data imply that antibiotic efficacy varied by organism and drug concentration. These organisms' antibiotic resistance mechanisms and new antibiotic resistance methods need more study.
Insights
This study evaluated common antibiotics against E. coli and Lactobacillus. Antibiotic effectiveness varied by microorganism and concentration, indicating a need for further research into resistance mechanisms.
Area of Science:
- Microbiology
- Pharmacology
Background:
- Microbial imbalance in the oral cavity can lead to disease.
- Antibiotics are commonly used to combat pathogenic microorganisms.
Purpose of the Study:
- To assess the in vitro antibacterial activity of commonly used antibiotics against E. coli and Lactobacillus.
- To compare the efficacy of Augmentin (CV), Ceftriaxone-Cephalosporin (CF), and Linezolid against these microorganisms.
Main Methods:
- An in vitro agar-well diffusion method was employed.
- The Radius of Zone of Inhibition (RZI) was measured after 24 and 48 hours.
- Antibiotics tested included Augmentin (CV), Ceftriaxone-Cephalosporin (CF), and Linezolid at concentrations of 5 μl and 2.5 μl.
Main Results:
- For E. coli, RZI ranged from 0.8-1.4 mm, consistent across concentrations and time points.
- For Lactobacillus, RZI varied between 0.5-1.8 mm, showing differences based on antibiotic and concentration.
- Antibiotic efficacy demonstrated variability depending on the specific organism and drug concentration used.
Conclusions:
- The study confirmed the antibacterial action of tested antibiotics against E. coli and Lactobacillus.
- Findings suggest that antibiotic efficacy is organism- and concentration-dependent.
- Further investigation into antibiotic resistance mechanisms in these organisms is warranted.
