Using the `Biblatex` style from [here](https://tex.stackexchange.com/questions/20754/tuning-numbered-citations-as-footnote/20771#20771) and tweaking some other things I had some success but not for this thing in bibliography; I have a repeated species name, which is `Helicobacter pylori`, how to write a code to recognize this word, and may be some other words as well, so that Biblatext can write them in emphasized text once found in the .bib file? 

P.S. That word `Helicobacter pylori` can appear in different forms in titles of references, they all should be emphasized as they are species names, as following: 

* `Helicobacter pylori`
* `Helicobacter`
* `H. pylori`
* `H.pylori`, i.e., space in between is sometimes omitted
* `Helicobacteraceae`, though rarely

**Code:**

\begin{document}
The book reference  is here~\parencite{kennedy_pcr_2011}. This article has a bold year in the bibliographye~\parencite{vignali_il-12_2012}, whereas this one not~\parencite{akira_role_2000}. This article also with no year shown~\parencite{lu_duodenal_2005-1}, but has species name called ``\textit{Helicobacter pylori}'' that I want to be emphasized as it should be. If it is possible also to make the author name lower case, otherwise I have to hack this from within the Biblatex translator of Zotero citation manager. I am using TexStudio as \LaTeX{} IDE, while you may use a different one, but that should'nt be a problem anyway.How about using  \verb|multicite| commands of the \verb|Biblatex| neat package by citing all of the above \parencites{see,}{akira_role_2000, kennedy_pcr_2011, vignali_il-12_2012, lu_duodenal_2005-1}. Did you notice that the prenote ``see'' was bold, how to change that to normal?
