Characterization of bioactive compound isolated from Micromonospora marina KPMS1 and its activity against emerging antibiotics resistant strains of Klebsiella pneumoniae HAUTI7 and Proteus vulgaris HAUTI14

Multiple antibiotic resistances have increased gradually in many classes of antibiotics among the gram negative organisms like Klebsiella pneumoniae and Proteus vulgaris which are the major causes of infection among worldwide. Nearly a hundred urine samples were collected, among them 16 urine samples were having plasmid and its resistant to various antibiotics. This present investigation has determined the resistant plasmid pattern of multi drug resistant Klebsiella pneumoniae and Proteus vulgaris from urinary tract site isolated from hospital patients. The detection and characterization of antimicrobial metabolite derived from marine sediments that produce potent activity against multidrug resistant pathogen. The 16S rRNA sequencing results and phylogeny showed that the resistant bacteria belong to the genera of Klebsiella pneumoniae HAUTI7 and Proteus vulgaris HAUTI14. The antibacterial activity and the characterization of bioactive compound like FT-IR and NMR studies were performed to analyze the structural elucidation of active compounds derived from marine source Micromonospora marina KPMS1. The 16S rRNA sequences of Micromonospora marina KPMS1was deposited in the Gen bank with the accession number MH036351. The effective bioactive compound derived from marine sediments are virtually unlimited interest that control the emerging multiple antibiotic resistant strains.

Automated summary

The study observed the gradual increase of multiple antibiotic resistances in gram negative organisms such as Klebsiella pneumoniae and Proteus vulgaris, which are major causes of infection worldwide. Among nearly a hundred urine samples, 16 samples were found to contain plasmids with resistance to various antibiotics. The research focused on determining the resistant plasmid patterns in multi drug resistant Klebsiella pneumoniae and Proteus vulgaris isolated from urinary tract infection sites in hospital patients, as well as detecting and characterizing antimicrobial metabolites derived from marine sediments that exhibit potent activity against multidrug resistant pathogens.
