1.  Efficacy of fresh Aloe vera gel against multi-drug resistant bacteria in infected leg ulcers 
The Australasian Medical Journal  2012;5(6):305-309.
Background
Infected leg ulcers are major health problems resulting in morbidity and disability and are usually chronic and refractory to antimicrobial treatment.
Aims
The present study is aimed at determining the bacteria involved in leg ulcers and their resistance patterns to commonly used antibiotics as well as to determine whether Aloe Vera has antibacterial activity against multi-drug resistant organisms and promotes wound healing.
Method
A total of 30 cases with leg ulcers infected with multi-drug resistant organisms were treated with topical aloe vera gel and 30 age and sex-matched controls were treated with topical antibiotics. Culture and sensitivity was done from the wounds on alternate days and the ulcer was clinically and microbiologically assessed after 10 days. The results were compiled and statistically analysed.
Results
Cultures of the study group who were using aloe vera dressings showed no growth by the fifth day in 10 (33.3%) cases, seventh day in another 16 (53.3%) and ninth day in two of the remaining four cases (6.7%) while in two (6.7%) cases there was no decrease in the bacterial count. This means that of the 30 cases, 28 showed no growth by the end of 11 days while two cases showed no decrease in bacterial count. Growth of bacteria in study group is decreased from 100% (30 cases) to 6.7% (2 cases) by day 11 with P<0.001. Cultures of the control group did not show any decrease in the bacterial growth by day 11.
Conclusion
Aloe vera gel preparation is cheap and was effective even against multi-drug resistant organisms as compared to the routinely used topical anti-microbial agents.
