Quotes and commas in \bibitem

Question

I have followed Converting to bibitem in LaTeX to convert into the \bibitem format.

However, the results are not as good as when I would have used the regular references.bib file.

For example, one of my entries in the references.bib file is :

@inproceedings{dansereau2013decoding,
  title={Decoding, calibration and rectification for lenselet-based plenoptic cameras},
  author={Dansereau, Donald G and Pizarro, Oscar and Williams, Stefan B},
  booktitle={Proceedings of the IEEE conference on computer vision and pattern recognition},
  pages={1027--1034},
  year={2013}
}

This generates in my pdf as :

Now after compiling the latex file and generating the pdf, I copy the required \bibitem lines from the output.bbl log file which is obtained :

\bibitem{dansereau2013decoding}
D.~G. Dansereau, O.~Pizarro, and S.~B. Williams, ``Decoding, calibration and
  rectification for lenselet-based plenoptic cameras,'' in {\em Proceedings of
  the IEEE conference on computer vision and pattern recognition},
  pp.~1027--1034, 2013.

But now my pdf file generates as the following with this bibitem format :

The quotes and commas have drastically changed and do not look as presentable as the first result. How do I generate the \bibitem contents from the .bbl files to get the same style of commas and quotes like I would have using a simple references.bib file

EDIT:

I had inserted my orginal referneces.bib file using :

\bibliographystyle{ieeetr}
\footnotesize
\bibliography{references.bib}

The new article with the bibitem format has :

\reftitle{References}
\begin{thebibliography}{999}
\bibitem{dansereau2013decoding}
D.~G. Dansereau, O.~Pizarro, and S.~B. Williams, ``Decoding, calibration and
  rectification for lenselet-based plenoptic cameras,'' in {\em Proceedings of
  the IEEE conference on computer vision and pattern recognition},
  pp.~1027--1034, 2013.
