Fermented polyherbal formulation ameliorates the severity of acute multiple - antibiotics - resistantPseudomonas aeruginosainfected burn wound in rat burn model

Abstract

ABSTRACTPseudomonas aeruginosa, a Gram-negative opportunistic bacterium has emerged as a cause of life-threatening infections in topical burn wounds. Current therapeutic approaches thru wound dressings and systemic medicines are far from satisfactory; multiple-antibiotic-resistance shown by pathogens contribute to failures of therapy causing mortality. This animal study was conducted to check efficacy of one Ayurveda based fermented polyherbal preparation (AP 01) against multiple antibiotic resistantPseudomonas aeruginosa HW01infected rat burn wounds. AP-01 was applied on artificially inflected burn wound on rat model infected with Multiple Antibiotics ResistantPseudomonas aeruginosato register the healing effects in terms of reduction in residual wound area percentage, presence of C-reactive protein in blood, presence of viable bacteria colony while keeping conventional antibiotics as positive control. The polyherbal preparation had reduced the infected residual burn wound area at 40.63% ± 0.69 from the initial burn wound area within two weeks after a single intervention; whereas residual burn wound area remained much higher in case of animals left untreated and in case of the animals treated with control drug. Restoration to normalcy of serum C-reactive protein level were also achieved earlier in case of polyherbal AP-01 treated groups than other groups. Fermented formulation using components of AP-01 singly or in different combinations were never been tested earlier for topical application in infected burn-wound. The formulation AP-01 was found superior in terms of rate of healing and control of infection by multiple-antibiotic-resistantP. aeruginosastrains in burn wounds in rat model.
