The UC San Fransisco team will move forward with Phase II: 'Quantitative Examination of Seasonal Prevalence & Geographic Distribution of Honey Bee Pathogens & Correlates to Colony Health'.  After monitoring commercial honey bee colonies for 10 months, Phase I established a baseline of pathogen prevalence in healthy bee colonies.  Dr. DeRisi explains that "Establishing a comprehensive list of pathogens is critical to future studies aimed at understanding how these pathogens affect honey bee health and their potential role in CCD."  The next step will delve deeper into the 'hive'.  Key samples such as seasonal points (the summer and winter pathogen peaks), mite-infested and pesticide-exposed samples, as well as beekeeper management styles will all be correlated to inform and guide migratory beekeeping practices.
