Ziekteverwekkers zijn een onderdeel van het natuurlijk systeem. Echter, de introductie van een nieuwe, onbekende ziekteverwekker kan de stabiliteit en het evenwicht van een systeem verstoren. The chytrid fungus Batrachochytrium dendrobatidis in the Netherlands: an overview of ten years study The fungal pathogen Batrachochytrium dendrobatidis [Bd] has been, and remains, one of the most challenging threats to herpetological conservation in particular, and wildlife conservation in general. In our country the global panzootic lineage (Bd-GPL) which emerged around 120-50 years ago from the Korean Peninsula occurs. Due to poor biosecurity and the scale of amphibian trade, this devastating fungus has been able to quickly spread over the world. In the Netherlands the fungus is endemic and is widespread. The interaction between host and pathogen is strongly context dependent. In the Netherlands, yellowbellied toads have a random chance of becoming infected, but once infected the probability of survival of the individual host significantly decreases. A high Bd prevalence coincides with increased adult mortality. A compensatory mechanism of increased recruitment prevails the collapse of populations, but this balance is fragile. Habitat deterioration (poor management), increasing temperatures and the introduction of novel Bd-strains all threaten to disturb this balance, hence vigilance remains important. The prevention of novel introductions is essential and therefore the implementation of disinfection protocols is of utmost importance. Additionally proper habitat management and a strong reservation towards restocking and repopulation projects is recommended
