General bacteriology

Unit responsible: 

Detecting, cultivating, isolating, identifying and characterising bacteria of animal origin

We detect, identify and monitor the evolution of bacteria that are indicative of or that are responsible for infectious diseases in animals, such as, for example, Staphylococcus aureus, coliform bacteria or mycoplasms. If we suspect that they are present but they are difficult to culture, we use molecular or immunological methods to identify these bacteria. We also advise health authorities to help them control and combat bacterial diseases effectively.

Besides routine diagnosis based on the detection of antibodies in the animals’ blood or on the culture of the bacteria being studied, we use or develop methods for detecting and characterising bacteria based on the analysis of their DNA. Whether it concerns identification markers, virulence properties or resistance to antibiotics, we are able to characterise all the bacteria that fall within our remit accurately.

We also collaborate with epidemiologists to monitor the evolution of resistance to antibiotics in bacteria isolated from farm animals, especially since the use of antibiotics is strictly regulated in veterinary medicine. We also study the emergence and propagation of antibiotic resistance genes, paying particular attention to those that present a risk to the success of antibiotic treatments in human medicine.

Finally, we collaborate with the authorities to identify bacteria that could be used as biological weapons for terrorist purposes.
