Urban honeybees could be used to gain insight into the microbiome of the cities in which they forage, which can potentially provide information on both hive and human health, reports a study published in Environmental Microbiome.
], and we hypothesized that their travel would permit them to interact with various microbial environments including air, water, and mammalian sources in addition to their known plant targets. We designed a pilot study to test for geo-specific microbial residues corresponding to all of these environments within material found in a hive.
Here we describe the results of a pilot study conducted with three rooftop beehives in Brooklyn, NY, where we evaluated the potential of various hive materials to reveal information as to the surrounding metagenomic landscape, and where we conclude that the hive debris are the richest substrate. Based on these results, we profiled four additional cities by collecting hive debris: Sydney, Melbourne, Venice and Tokyo.
~ 200 µL residual liquid was moved to an Eppendorf, and placed in the − 20 °C freezer until the DNA extraction step.The bee debris was diluted in a 1:5 ratio of grams of bee debris to mL of ultrapure water. The mixture was then heated in a water bath at 70 °C for 5 minutes in order to soften the debris and have it disperse in the liquid and then spun on the vortex vigorously.
