In vitro activity of augmentin against pathogenic bacteria and its comparison with other antibiotics
Abstract:
190 isolates from clinical specimens were tested in vitro to determine their susceptibility pattern against augmentin. Of the 132 strains of Enterobacteriaceae tested, 109 (82.6%) were susceptible. 41 (93.2%) of the 44 gram-positive bacteria tested were also susceptible to augmentin. Strains of Pseudomonas aeruginosa and Serratia marcescens were resistant to augmentin. However, augmentin showed increased activity against Escherichia coli, and Staphylococcus aureus when compared with ampicillin.
Insights
Augmentin demonstrated significant susceptibility against common clinical bacteria like Enterobacteriaceae and gram-positive strains. However, Pseudomonas aeruginosa and Serratia marcescens showed resistance to this antibiotic.
Area of Science:
- Microbiology
- Infectious Diseases
- Pharmacology
Background:
- Antibiotic resistance is a growing global health concern.
- Understanding antimicrobial susceptibility patterns is crucial for effective treatment.
- Augmentin is a widely used antibiotic for bacterial infections.
Purpose of the Study:
- To evaluate the in vitro susceptibility of clinical bacterial isolates to Augmentin.
- To compare Augmentin's activity against specific bacterial groups and with ampicillin.
Main Methods:
- 190 clinical bacterial isolates were tested for susceptibility.
- In vitro susceptibility testing was performed against Augmentin.
- Bacterial isolates included Enterobacteriaceae, gram-positive bacteria, Pseudomonas aeruginosa, and Serratia marcescens.
Main Results:
- 82.6% of Enterobacteriaceae (109/132) were susceptible to Augmentin.
- 93.2% of gram-positive bacteria (41/44) were susceptible to Augmentin.
- Pseudomonas aeruginosa and Serratia marcescens exhibited resistance to Augmentin, while Escherichia coli and Staphylococcus aureus showed enhanced susceptibility compared to ampicillin.
Conclusions:
- Augmentin is effective against a majority of Enterobacteriaceae and gram-positive clinical isolates.
- Resistance to Augmentin was observed in Pseudomonas aeruginosa and Serratia marcescens.
- Augmentin shows improved efficacy over ampicillin for certain bacteria, including Escherichia coli and Staphylococcus aureus.
