Comparative studies on the antimicrobial activity of Terminalia arjuna and Aloe vera against community associated drug resistant Staphylococcus aureus in pus from carbuncles of adults
The emergence of methicillin (oxacillin) resistant Staphylococcus aureus (MRSA) causes a serious health problem in developing as well as developed countries. Present study was conducted to isolate community associated Staphylococcus aureus in the pus from the carbuncles of adult persons including their antibiotic susceptibility and to study the antimicrobial effect of aqueous extract of bark of Terminalia arjuna and Aloe vera gel against drug resistant Staphylococcus aureus. Pus samples from carbuncles of adult persons of both sexes belonging to low socio-economic condition were collected and Staphylococcus aureus were identified through several biochemical tests. Antibiotic susceptibility and antimicrobial effect of aqueous extract of bark of Terminalia arjuna and Aloe vera gel were studied by agar well diffusion method. Moreover, present study revealed that 49 (65.3%) and 47 (62.67%) of Staphylococcus aureus isolates were resistant to Erythromycin and Clindamycin respectively while 39 (52.0%) Staphylococcus aureus were resistant for both Erythromycin and Clindamycin. Beside this 19 (48.72%) of them (resistant to both Erythromycin and Clindamycin) were also resistant to Methicillin and 11 (57.89%) of the Methicillin-resistant Staphylococcus aureus isolates were observed to be resistant to Vancomycin. Present study revealed that community associated Vancomycin resistant Staphylococcus aureus (which are also MRSA) were present in carbuncle. It was observed that aqueous extract of bark of Terminalia arjuna had good antimicrobial role against the Vancomycin resistant Staphylococcus aureus (which were also MRSA) whereas Aloe vera gel was found to be less important against them.
