To investigate the anti-bacterial activity of crude extracts of Mintha pipertia and Allium sativum against throat infection causing bacteria streptococci collected from various diagnostic laboratories and hospitals of Mingora swat

Streptococcus (S) pyogenes one of the major Gram-positive pathogens responsible for upper respiratory tract and nosocomial infections. This is a Gram Positive, aerobic, no motile, and non-spore-forming ubiquitous bacteria. The present study was conducted to evaluate the in vitro antibacterial activity of ethanol and aqueous extract of peppermint and garlic against 29 isolates of S. pyogenes recovered from the throat sample of patientsin Swat KPK-Pakistan. These isolates were purified to identify the target bacterial isolates by gram staining and biochemical tests. The Agar dilution and well method was applied for the antibacterial activity of garlic and peppermint extracts. All of the subject isolates were exposed to different concentrations of peppermint. MIC of aqua extract of peppermint was 250µL/mL and ethanol extract was 100µL/mL. The zone size was 29mm and 36mm respectively. So the ethanol extract of peppermint was found to be more effective as compared to the aqueous extract. On the other hand, Garlic has shown equal effectiveness of water and ethanol extraction with MIC value of all is 50µL/mL and zone of inhibition   was 38mm. Ciprofloxacin antibiotic disk was used as reference standard.
