Ioannis Arsenakis was born on 11 December 1984 in Chicago, Illinois, USA. He graduated in March 2010 from the Faculty of Veterinary Medicine of Aristotle University of Thessaloniki, Greece. He then received a scholarship grant to continue his studies at the Roslin Institute of the Royal (Dick) School of Veterinary Studies in Edinburgh, Scotland. He graduated on June 2012 and received a Master’s degree in Animal Biosciences (awarded with Distinction). He then continued in the Republic of Ireland, where he worked as a poultry veterinarian, taking care of broiler and broiler breeder flocks. From August 2013 until October 2018, he was a member of the Unit of Porcine Health Management (lead by Prof. Dr. D. Maes) at the Faculty of Veterinary Medicine of Ghent University, Belgium. He has completed the residency program for the European College of Porcine Health Management. Apart from clinical training, he also performed studies focusing on the optimization of vaccination strategies against Mycoplasma hyopneumoniae in peri-weaned piglets and breeding sows. Other studies he conducted and published focused on the use of autogenous vaccination in sows for the control of exudative epidermitis in nursery pigs and the evaluation of semen quality of Belgian Piétrain boars. Ioannis has supervised Master’s theses of final-year Veterinary Medicine students and contributed to the conception and development of several field trial protocols related to enzootic pneumonia, assessment of the colostrum quality as well as optimization of swine artificial insemination techniques. He has been an invited speaker on several national and international conferences, and he has authored several papers in international peer reviewed scientific journals.

Korte beschrijving

Mycoplasma hyopneumoniae (M. hyopneumoniae) is the primary agent of enzootic pneumonia, a chronic respiratory disease which results from infection of M. hyopneumoniae and other secondary bacteria, and inflicts major economic losses to the pig industry. One of the ways frequently used to control M. hyopneumoniae infections worldwide is vaccination. The most common vaccination strategy in practice is vaccination of the piglets during suckling or at weaning. Currently, it is not known whether the efficacy of vaccination against M. hyopneumoniae can be influenced by the weaning process when vaccination is applied at the day of weaning. Concerning the breeding sow population, vaccination of gestating sows against M. hyopneumoniae is not frequently practiced under field conditions. Nevertheless, breeding sows could be a reservoir of M. hyopneumoniae infections for the suckling and recently weaned piglets in endemically infected herds. Thus, it is interesting to investigate whether vaccinating sows during gestation could decrease the percentage of their offspring that is colonized with M. hyopneumoniae at weaning as well as in the nursery units. The general aim of this thesis was to investigate different vaccination strategies against M. hyopneumoniae
