Goodbye 2011 and Hello New Science Year 2012: JIDC Postcards 2011- a Wrap-up

Good Bye 2011.  Hello New Science Year! Its 2012!  I hope everyone had a fabulous 2011 and rang in 2012 with a (big) bang!

There is so much a new year brings, especially in science. A new year with many possibilities. New conferences to attend (yeah!). Papers to publish. Exciting projects to start.  And new posts to write for the JIDC Blog!

To move forward in a guided direction I often feel we need to review the past.  What conferences were attended?  Were they beneficial? What papers were we able to publish last year? Were they well received? What are the stages of the current projects? Are they close to a publication? Are they close to completion?

And here at the JIDC Blog, what were the posts on the Blog over the last year?  Were they helpful to readers and authors? Did they promote scientific discussion? Were the Blog and the Blog Posts a good resource for research information? – This was my main goal when starting the JIDC Blog.  My hope was that the Blog would be useful to JIDC readers and authors alike as an information resource as well as a point for discussions.  I also hoped that it would be a valuable tool for non-JIDC members and help educate new people about JIDC.

So shall we review?

There is a blog tradition that I have only just learned about.  The tradition is that the first post of the New Year should be a listing of all the first sentences from the first post of every month from the previous year.

Below is a listing of all of the first Posts of every month in 2011 and the first sentences from each.  I have also added my personal notes from each post.

Here we go…

June 2011 — JIDC Postcards: The JIDC Blog

Hi, and welcome to JIDC’s blog. 

I was sooo excited…and nervous to introduce the Blog to the JIDC community and the world.  Would anyone read it? Would anyone like it?  Would it be a Blog that we could be proud of? Only you can answer these questions for me. 

 

July 2011 – Olga:  From Mozambique to Brazil

A Challenge!! An Opportunity!!

My name is Olga André Chichava, and I’m a young biologist fromMozambique!

I absolutely loved this post from Olga. Her story gave an incredible view into the life of a research student who is also a mother.  I was inspired to see her courage to move to a foreign country and her drive to build her masters project.   She shared her passion for research as well as life with us. This post was featured on the headlines of Microbiology Daily, I was so proud. Also, this post is the most popular post on the Blog.

 

August 2011 – Milliedes in Kashmir,India

Insects have been found in Marrhama, a village in Blok Trehgam in the District of Kupwara Jammu and Kashmir, India. The main water source used for drinking purposes is badly affected by the insects.

This post from Dr. Kadri highlighted problems that affect regional areas which can easily go unnoticed to the rest of the world.  I am so glad that he shared this experience so that more people can be aware of such difficulties that face communities. This is the second most popular post of all time on the Blog and I am happy that it has reached so many people!

 

September 2011 – The First Annual Conference on Drug Therapy in TB Infection

The Africa Health Research Organization, AHRO, presents the International Conference on Drug Therapy in TB Infection

What: First International Conference on Drug Therapy in TB Infection
When: 6-7 January 2012
Where: Edinburgh Scotland
Who: Presented by AHRO,Africa Health Research Organization

It was great to post about this conference.  Since the conference was just completed, I hope that everything went well and it was a successful event.  Also, I would love to hear a roundup of the conference by anyone who attended.  Please contact me if you are interested in writing a Blog Post describing this meeting.

 

October 2011 – And the winner is…! JIDC Open Access Week#4

And the winner is….I just couldn’t help it.  I have enjoyed Open Access Week and the JIDC T-shirt give-away that I could not just draw only 1 name.  So I picked 6!

Ooooo this was an exciting one.  I was incredibly happy to share JIDC and the JIDC T-shirts with readers and authors! If you are a winner and you haven’t contacted me and would still like at T-shirt, please let me know.

 

November 2011 – Publishing a Scientific Article in JIDC

How do I publish a scientific paper?…This question is asked by all young scientists. 

How do you write a scientific paper? There are so many directions one can take when putting their research together. I hope this helped authors organize themselves when preparing manuscripts for JIDC.  In addition to this Post, if you have other specific questions about writing a paper or you have a particular writing topic you would like to see a post about, please don’t hesitate to let me know.  I am currently preparing a post how I write a scientific paper to share with you.

 

December 2011 – ReR – MedToday!

Memento te hominem esse. – Remember that you are human.

What an important point that is! Remember you are human. We are all vulnerable and delicate aren’t we? I am so happy to have posted the special work of ReR-MedToday! The importance of support during times of ill health can’t be overstated. I am sure the families touched by this organization are forever grateful.

 

Thats a Wrap! 

So that’s the JIDC Blog for 2011.  I hope 2012 brings just as fabulous Posts and discussions as 2011 did.

I would like to thank everyone who contributed to the Posts and Discussion of the 2011 JIDC Blog!  In no particular order, BIG THANKS to:

Ana: Salmonella in Sardinia

I am please to present a Postcard written by the lovely Ana Carolina!  Ana is a microbiologist from Brazil who carried out part of her PhD in Sardinia, Italy studying salmonella.  I was lucky enough to work in Sardinia at the same time as Ana Carolina while I was completing my Visiting Professorship at the University of Sassari.  Ana works incredibly hard but always with a smile on her face.  It was a delight to see her everyday. I am happy to call Ana a colleague and a friend!

I went to Sardinia!

In 2008 I started my PhD in food microbiology at the Federal University of Rio Grande do Sul (UFRGS), in Porto Alegre, Brazil. It was a moment of transition, because I did my master’s degree working with mycotoxins and now I decided to work with Salmonella. I was accepted to a group that has studied the occurrence of outbreaks of salmonellosis in the state of Rio Grande do Sul (RS) (southern Brazil) for 10 years, the Laboratory of Food Microbiology of the ICTA/UFRGS.

 
 

This research group had already made several discoveries regarding Salmonella Enteritidis (S. Enteritidis).  In previous work done in the Laboratory of Food Microbiology, the spvR gene (Salmonella plasmid virulance)was identified in 82.7% of S. Enteritidis infections involved in food poisoning cases which occurred in RS from 1999 to 2000 [1] . These isolates were also characterized according to their antibiotic resistance, and it was shown that there was a high percentage of sensitivity to most of the drugs tested [1] . Oliveira et al. [2] demonstrated that strains of S. Enteritidis isolated from these outbreaks which occurred in RS in 2001 and 2002 showed similar resistance profiles as the lines of the preceding period.  Interestingly, it was identified that one strain of S. Enteritidis was involved in more than 95% of the salmonellosis cases which occurred in RS [2]. Importantly, other work from the laboratory evaluated the resistance of S. Enteritidis SE86 to disinfectants commonly used in food industries [2]. It was concluded from this work that peracetic acid, sodium hypochlorite and quaternary ammonium were able to inactivate S. Enteritidis SE86; however, this strain was more resistant to the concentration of 200 ppm sodium hypochlorite (commonly used in Brazil).

Continuing the investigation into the strains of S. Enteritidis which are responsible for salmonellosis and acid resistance in RS, my PhD project aims to investigate the expression of resistance genes which may contribute to the involvement of this predominant strain of S. Enteritidis in food in Brazil. That was the part of the thesis that took me to the Laboratorio di Microbiologia at Univesrsità degli Studi di Sassari.

 

So, with the desire of live outside Brazil and to enrich the Brazilian science, I went to Sardinia or Sardegna, Italy.  Sardinia is a large Island in the Mediterranean Sea.

 

To realize this dream, I sent emails to  Professore Salvatore Rubino (Editor-in-Chief of JIDC) and Professore Sergio Uzzau, asking if I could perform one year of research in their laboratory. After their positive response, I applied for a scholarship to Capes, a Brazilian funding agency for research. The result was one year living in Sassari (2009 to 2010), developing my thesis.

In Sardinia genetic modifications in the Brasilian S. Enteritidis (strain SE86) were preformed. With the help of Doctoressa Donatella Bacciu, we performed knockout techniques [3] and epitope tagging [4] in four different genes to check the expression of these strain’s forward acidity and high temperatures, results which I am currently writing up.

It was an incredible experience! Sardinia has breathtaking landscapes, incredible history and very nice people. The university gave me all necessary support for my research; with great colleagues guiding me … I learned a lot, both inside and outside the laboratory. I returned to my country with lots of knowledge: the language, the laboratory techniques, dear friends. I love Sardinia!

 Today I am writing the articles and the thesis, because I have to finish my PhD

 Post doc? Why not? Science takes us to places that we never dreamed… 

Ana

 Ana is 31 years old. She studied biology (2000 until 2004), then did a two year master degree ( between 2005 and 2007) working with  Aspergillus flavus (food microbiology). In 2008, she started her PhD (food microbiology) at the Federal University of Rio Grande do Sul (UFRGS) in Porto Alegre, Rio Grande do Sul, Brazil. Ana’s story to be post in Portuguese soon!
