Virginia Aragón graduated from the Faculty of Biological Sciences at the University of Navarre in 1990. Later on, she became a Ph.D. from the same University, where she wrote her thesis on Brucella ant the Department of Microbiology under the guidance of Dr. Moriyón (1994). In 1996 she travelled to the US, where she worked at the laboratories of Dr. Dreyfus (University of Missouri-Kansas City), Dr. Cianciotto (Northwestern University Medical School-Chicago) and Dr. Hansen (University of Texas-Southwestern University Medical Center-Dallas), on different aspects of bacterial pathogenicity.

Since 2003, Dr. Aragón works at the Centre de Recerca en Sanitat Animal (CreSA) [Animal Health Research Centre], that is the IRTA's animal health programme. She has become established as the main researcher on pig respiratory diseases. Her research at the IRTA (Food and Agriculture Research and Technology Institute) has focused on the genomic and functional characterisation of Haemophilus parasuis, including the pathogenicity molecular mechanisms. Currently, she is leading a project aimed at the determining of the respiratory microbiota and its role on the keeping of the swine health. The final goal of her research is the control of the porcine respiratory diseases through alternative methods to antibiotics, such as vaccinations and probiotics. The results of her studies have been published in 46 SCI international scientific magazines in the areas of veterinary medicine/science and microbiology, she has written a chapter of the book Diseases of Swine, has given more than 50 lectures at scientific meetings, has published several research articles, and has given technical speeches. She has participated in 16 research projects, in 4 of them as the meain researcher. She has also supervised 4 Ph.D. theses and 8 Msc theses. She also supervises visitung students from other laboratories.

Immunity and serotype

17-Sep-2009 (10 years 2 months 2 days ago)
The decrease in the contact time between the mother and her piglets, due to the common practice of early weaning, has led to the appearance of some piglets that are not completely colonised or that have not acquired a sufficient level of maternal antibodies. On mixing with other litters, these piglets are faced with distinct strains while lacking the necessary antibodies against the disease.
Immunity and serotype

Epidemiology and typing

02-Sep-2009 (10 years 2 months 17 days ago)
It is important to be able to identify the distinct circulating strains and to differentiate between the strains that are merely colonisers and those that have the capacity to produce disease. With this aim various methods of classification of strains or “typing” of H. parasuis have been developed.
Epidemiology and typing

Risk factors

06-Jul-2009 (10 years 4 months 13 days ago)
On a conventional farm with no problems with Glässer’s disease, it is possible to isolate various strains of Haemophilus parasuis which colonise piglets while being in balance with the animal’s immunity without producing pathology.
