New Server

SLU 40 years logoFrom the beginning, we have developed the VetBact database with the needs of the students in the veterinary program in mind, but we also want it to be a useful resource for many workers outside the Swedish University of Agricultural Sciences (SLU).

When we first went online, in 2006, the database was hosted by our partner during the early years of development, the National Vete­rina­ry Institute (SVA). VetBact was at that time an integral part of the SVA website.

As VetBact grew and we introduced more student-oriented modules such as quizzes, it became clear that it needed its own domain name and server. Therefore we acquired the domain vetbakt.se, and moved the system to a commercial web hosting service. As we continued to develop the system, it soon became evident that most of our users were in countries other than Sweden, so we changed the domain to vetbact.org and moved the system to a more powerful server.

With the further development of even more course-related functionality, e.g. the virtual laboratory VetBactLab and video lectures, it now seems appropriate to take the next step in that we now bring the system back home to its roots by moving it to a server run by the university IT department. Incidentally, this means that VetBact can now also be reached using an alternate URL: http://vetbact.slu.se/.

The URLs have changed in that we no longer use “/vetbact” nor “/vetbactblog” as part of the URL path. Although we hope that most links to pages on the website will continue to get you to the right place despite this change, please check/update your links and bookmarks!

The bacteriology course for veterinary students

Students in the lab.

Students are identifying bacteria during the 2017 course in bacteriology for veterinary students at the Swedish University of Agricultural Sciences.

In Sweden the course in bacteriology and food microbiology for veterinary students started on August 28 this year (2017) and will last until October 5. The bacteriology course is given during the second year of the veterinary programme and is attended by about 100 students. There is only one veterinary school in Sweden. The course consists of lectures and laboratory work. During the course, VetBact is used as a source of information, to check the knowledge and to perform virtual experiments. Links to lectures on YouTube can also be found on VetBact.

Phylogenetic trees of Actinobacteria

Phylogenetic tree of Actinobacteria.

Phylogenetic tree based on 16S rRNA gene sequences of some members of the phylum Actinobacteria.

Phylogenetic trees for all members of the phylum Actinobacteria in VetBact (27 species/subspecies) have now been included. The only group of bacteria for which there are no trees available in VetBact is the class Gammaproteobacteria, which also is the biggest class with 61 members included in VetBact.

The phylogenetic trees in VetBact are based on prealigned 16S rRNA gene sequences retrieved from RDP (Ribosomal Database Project). The trees have been constructed on line by using the computer program “Tree Builder” at the website of RDP. The images of the trees were further revised by using the GNU Image Manipulation Program – GIMP.

Mycoplasma hyopneumoniae and M. hyorhinis

Mycoplasma hyorhinis.

Colonies of Mycoplasma hyorhinis cultivated on commersially Mycoplasma-Experience medium  for 7 days. The length of the scale bars is equivalent to 1 mm. Credit: Joachim Frey and Bettina Trueb.

Thanks to Professor Joachim Frey (Institute of Veterinary Bacteriology, University of Bern, Swit- zerland), we have got images of colonies of Mycoplasma hyopneumo- niae and M. hyorhinis to by used on the corresponding bacterial pages of VetBact. Mycoplasmas form very small colonies (0.1-1 mm in diameter) and to see details of the colonies, a microscope has to be used. The colonies are in general umbonated and are said to look like fried eggs. However, these two mycoplasmas form atypical colonies with very poorly defined “egg yolk”.

MALDI-TOF MS available at VHC, SLU

MALDI-TOF MS

The instrument for MALDI-TOF MS, which i.e. can be used for identification of bacteria, is placed at BVF, VHC, SLU.

Since some months back there is an instrument for MALDI-TOF MS (Matrix Assisted Laser Desorption – Time Of Flight Mass Spectrometry) available for analyses at VHC (Centre for Veterinary Medicine and Animal Science), SLU (Swedish University of Agricultural Science. The instrument is placed at the BVF (Department of Biomedical Sciences and Veterinary Public Health) and it is ready to be used in research projects, routine diagnostics and teaching. MALDI-TOF kan for instance be used for identification of bacteria, mold and fungi.

For more information about costs etc. contact:

New phylogenetic trees in VetBact

25_clostridium_ver3 So far only few phylogenetic trees have been included on the bacterial pages of VetBact. However, within a few months we hope to increase the number of trees significantly. We have started to constuct trees for the genus Clostridium and a phylogenetic tree can now be found on all clostridia pages of VetBact. The trees are based on prealigned 16S rRNA gene sequences retrieved from RDP (Ribosomal Database Project). The trees have been constructed on line by using the computer program “Tree Builder” at the website of RDP. The images of the trees were further revised by using the GNU Image Manipulation Program – GIMP.

Visitors from Alexandria University

An introduction to VetBact

VetBact has been demonstrated to four very interested researchers (Ms. Walaa Osama Ahmed Abdelkader Khattab, Mrs. Salma Adnan Ahmed Bekhit, Dr. Neveen Fahmy Mohamed Agamy Hassanin and Mr. Mohamed Anwar Mohamed Sultan Mahgoub) from the High Institute of Public Health, Alexandria University in Egypt.

We have currently four researchers from the High Institute of Public Health, Alexandria University, Egypt visiting our university (Swedish University of Agricultural Sciences – SLU) for three weeks. The visit is a part of the start-up of a new three-year project ‘Molecular Epidemiology of Campylobacter spp. in Broiler Meat and Quantitative Modeling of the Risk of Human Campylobacteriosis in the Egyptian Setting’ funded by the Swedish Research Council. For more information about the project, please contact Sofia Boqvist (sofia.boqvist@slu.se) at SLU.
