Use of Gas Chromatography and SPME Extraction for the Differentiation between Healthy and Paenibacillus larvae Infected Colonies of Bee Brood—Preliminary Research

Paenibacillus larvae is a deadly pathogen for bee brood, which can lead to the death of entire colonies. The presence specific volatile organic compounds (VOCs) in hive may be related occurrence this bacterium brood. Compositions those fractions present healthy brood from control colonies and without symptoms infection collected infected by P. were compared using gas chromatography coupled with mass spectrometry (GC-MS) solid phase microextraction (SPME). Among seven detected quantified, relative concentrations 3-carene limonene significantly differentiated Based on ratio analysis, samples terms number emitted VOCs.
