Sample name: Staphylococcus aureus Treated A (Given Name: 3A)
Source of the Sample: On 23rd January 2008, Mr. Mahendra Kumar Trivedi visited our R&D facility at Bangalore to observe the impact of his treatment modality on various groups of bacteria at the level of DNA fingerprinting. On the same day, he subjected Staphylococcus aureus, ATCC no-49831 to his said treatment modality that were handed over to Ms. Bindu in two separate tubes named as Series A & Series B.
Following the treatment, after few days, we sub cultured the inoculums of treated Series A & Series B into Treated Sample A1 and Treated Sample B1 respectively.
All four treated samples (Treated sample A, Treated sample B, Treated Sample A1 And Treated Sample B1) along with Control were analyzed for DNA fingerprinting by RAPD analysis. And the comparative results are as follows.
 
 
  • The percentage of true polymorphism observed between Control & Treated sample A of Staphylococcus aureus sample is on an average 79%.
  • The percentage of true polymorphism observed between Control & Treated sample A1 of Staphylococcus aureus sample is on an average 45%.
  • The percentage of true polymorphism observed between Control & Treated sample B of Staphylococcus aureus sample is on an average 74%.
  • The percentage of true polymorphism observed between Control & Treated sample B1 of Staphylococcus aureus sample is on an average 52%.
  The details of the same report have been issued to him. As per his request, we have preserved all the treated samples. Out of which, preserved Treated Sample A was requested to analyse for Bacterial Identification Service/ Test based on 16S rDNA data by Mr. Trivedi on 9th April 2008.The original source (before the treatment) of preserved Treated Sample A is Staphylococcus aureus, ATCC no-49831.
Steps Involved: 1. Genomic DNA was isolated from the pure culture pellet after treatment provided by Mr. Mahendra Kumar Trivedi

2. Using consensus primers, the ~1.5 kb 16S rDNA fragment was amplified using high-fidelity PCR Polymerase.

3. The PCR product was cloned and plasmid DNA was bi-directionally sequenced using the forward, reverse and an internal primer.

4. Sequence data was aligned and analyzed for finding the closest homologs for the microbe.
 
Result:
  1. Based on nucleotides homology and phylogenetic analysis the Microbe (Sample: 3A) was detected to be Staphylococcus aureus (GenBank Accession Number: L37597).

  2. Nearest homolog species was found to be Staphylococcus simiae (Accession No. AY727530).

  3. Information about other close homologs for the microbe can be found from the Alignment View table.
