Unfortunately, the original version of the article [1] contained an error. The author has brought to our attention that the article title is truncated in the published version. The correct title is American foulbrood in a honeybee colony: spore-symptom relationship and feedbacks between disease and colony development. Instead, it was published inadvertently as American foulbrood in a honeybee colony: spore symptom relationship and feedbacks due to an error occurred during the production process.
