Assessment of Antibiogram of Multidrug-Resistant Isolates of Enterobacter aerogenes after Biofield Energy Treatment

provided by EOL authors

Abstract:

Enterobacter aerogenes (E. aerogenes) has been reported as the versatile opportunistic pathogen associated with the hospital infections worldwide. The aim of the study was to determine the impact of Mr. Trivedi’s biofield energy treatment on multidrug resistant clinical lab isolates (LSs) of E. aerogenes. The MDR isolates of E. aerogenes (i.e., LS 45 and LS 54) were divided into two groups, i.e., control and treated. Samples were analyzed for antimicrobial susceptibility pattern, minimum inhibitory concentration (MIC), biochemical study, and biotype number using MicroScan Walk-Away® system, on day 10 after the biofield treatment. The antimicrobial sensitivity assay showed 14.28% alteration out of twenty eight tested antimicrobials with respect to the control. The cefotetan sensitivity changed from intermediate (I) to inducible β-lactamase (IB), while piperacillin/tazobactam changed from resistant to IB in the treated LS 45. Improved sensitivity was reported in tetracycline, i.e., from I to susceptible (S) in LS 45, while chloramphenicol and tetracycline sensitivity changed from R to I in treated LS 54. Four-fold decrease in MIC value was reported in piperacillin/tazobactam, and two-fold decrease in cefotetan and tetracycline in the biofield treated LS 45 as compared to the control. MIC results showed an overall decreased MIC values in 12.50% tested antimicrobials such as chloramphenicol (16 μg/mL) and tetracycline (8 μg/mL) in LS 54. The biochemical study showed an overall 45.45% negative reaction in the tested biochemical in both the treated isolates as compared to the control. A change in biotype number was reported in MDR isolates (LS 45 and LS 54), while in LS 54, altered biotype number, i.e., 0406 0374 as compared to the control (7770 4376), with identification of the new species as Stenotrophomonas maltophilia with brown color as special characteristic. The study findings suggest that Mr. Trivedi’s biofield energy treatment on clinical MDR isolates of E. aerogenes has the significant effect on altering the sensitivity of antimicrobials, decreasing the MIC values, changed biochemical reactions, and biotype number.

Characterization of Phenotype and Genotype of Biofield Treated Enterobacter aerogenes

provided by EOL authors

Abstract:

Enterobacter aerogenes (E. aerogenes) has been commonly described as a versatile opportunistic pathogen in hospital infections. The aim of the present work was to evaluate the impact of biofield treatment on E. aerogenes for its phenotypic and genotypic characteristics. E. aerogenes bearing ATCC 13048 (American Type Culture Collection) was procured from Bangalore Genei, in sealed pack and divided into control and treated groups. Treated group was subjected to Mr. Trivedi’s biofield treatment and analyzed for antimicrobial susceptibility, minimum inhibitory concentration (MIC), biochemical reactions, and biotype using automated MicroScan Walk-Away® system. In addition, treated group of E. aerogenes was evaluated for DNA polymorphism by Random Amplified Polymorphic DNA (RAPD) and 16S rDNA sequencing to establish the phylogenetic relationship of E. aerogenes with different closely related bacterial species. Antimicrobial susceptibility results showed an alteration of 14.28% among twenty-eight tested antimicrobials. Similarly, 15.65% tested antimicrobials showed an alteration in MIC values. Chloramphenicol showed improved sensitivity i.e. resistant to susceptible after biofield treatment, with the support of decreased MIC by two folds (i.e. >16 to ≤8 µg/mL). Norfloxacin also showed decrease MIC by two folds (i.e. 8 to ≤4 µg/mL) as compared to control. Biofield treatment showed an impact on biochemical reactions (9.09%) followed by a change in biotype number (7770 5272) in treated group with respect to control (7770 5372). Using RAPD analysis, sample showed an average range of 4 to 42% of polymorphism, while 16S rDNA study showed that treated sample was detected as Kluyvera cryocrescens (GenBank Accession Number: AM184245) with 97% identity of gene sequencing data, which was nearest homolog species to Enterobacter aerogenes strain: C1111 (Accession No. AB244467). These results suggest that Mr. Trivedi’s unique biofield treatment can alter the antimicrobial sensitivity pattern, thus it can be used as alternate energy medicine in future.

Klebsiella aerogenes

provided by wikipedia EN

Klebsiella aerogenes,[2] previously known as Enterobacter aerogenes, is a Gram-negative, oxidase negative, catalase positive, citrate positive, indole negative, rod-shaped bacterium.[3] The bacterium is approximately 1–3 microns in length, and is capable of motility via peritrichous flagella.[4]

Klebsiella aerogenes is a nosocomial and pathogenic bacterium that causes opportunistic infections including most types of infections. The majority are sensitive to most antibiotics designed for this bacteria class, but this is complicated by their inducible resistance mechanisms,[5] particularly lactamase, which means that they quickly become resistant to standard antibiotics during treatment, requiring a change in antibiotic to avoid worsening of the sepsis.

Some of the infections caused by K. aerogenes result from specific antibiotic treatments, venous catheter insertions, and/or surgical procedures. K. aerogenes is generally found in the human gastrointestinal tract and does not generally cause disease in healthy individuals. It has been found to live in various wastes, hygienic chemicals, and soil. The bacterium also has some commercial significance – the hydrogen gas produced during fermentation has been experimented with using molasses as the substrate.

K. aerogenes is an outstanding hydrogen producer. It is an anaerobic facultative and mesophilic bacterium that is able to consume different sugars and in contrast to cultivation of strict anaerobes, no special operation is required to remove all oxygen from the fermenter. K. aerogenes has a short doubling time and high hydrogen productivity and evolution rate. Furthermore, hydrogen production by this bacterium is not inhibited at high hydrogen partial pressures; however, its yield is lower compared to strict anaerobes like Clostridia. A theoretical maximum of 4 mol H2/mol glucose can be produced by strict anaerobic bacteria. Facultative anaerobic bacteria such as K. aerogenes have a theoretical maximum yield of 2 mol H2/mol glucose.[6]

It may spoil maple sap and syrup.[7]

Owing to diverse metabolites, namely acids and alcohols, produced by such a strain in conjunction with its capability of utilizing different sugars, the metabolic behavior and growth of K. aerogenes can significantly vary under different conditions.[8]
