An inter-laboratory proficiency test is being organized to assess the performance and conformity of laboratories in detecting Paenibacillus larvae and Melissococcus plutonius, the causative agents of American and European foulbrood in honeybees.

Objectives:

To evaluate the accuracy and reliability of results provided by participating laboratories in the detection of these pathogens.

 

Diagnostic Methods Assessed:
