Self-introduction
The aim of my studies is to contribute food (milk) supply and food (milk) safety through the studies related to udder health (mastitis) and milk hygiene (contamination of foodborne zoonotic pathogens) in dairy animals. One of the strategies to achieve my aims is to clarify the mechanisms of bacterial intramammary infection especially by Enterobacterales in dairy animals.
