Phytochemical analysis and in vitro synergistic efficacy of leaf extracts of Acacia polyacantha and antibiotics against MDR Klebsiella SPP.

Emerging Multidrug-resistant problem is a major concern. Klebsiella sp. can lead to a wide range of disease causing pathogen namely  pneumonia, urinary tract infections, septicemia, meningitis, diarrhea and soft tissue infections and development of MDR against commonly used antibiotics making the case difficult to manage. Total 525 Clinical samples were screened for isolation of Klebsiella sp. Total 36 isolates belonging to Klebsiella sp. Were obtained. 29(8.06%) isolates were associated with urinary tract infection (UTI), 6(12%) with sputum and 1(1.54%) was associated with blood. Antibiogram study of these isolates revealed that all these isolates are resistant to several antibiotics out of 34 antibiotics tested. Cold and hot acacia leaf petroleum ether extract, cold and hot acacia leaf chloroform extract, cold and hot acacia leaf acetone extract, cold and hot acacia leaf methanol extract and cold and hot acacia leaf water extract were used for synergistic study. Qualitative phytochemical analysis these leaf extracts showed the prominent presence of alkaloids, Carbohydrates and glycosides, proteins and amino acids and phytosteroids. The studies on these extracts of Acacia polycantha and antibiotics on susceptibility of resistant Klebsiella isolates showed that both cold and hot solvent extracts are effective on antibiotics. The effectiveness shown by these extracts may be useful in evaluating the efficacy of combination therapy against MDR-Klebsiella sp.
