A Case of Paenibacillus alvei Cellulitis in Immunocompetent Patient

Bacillus species are ubiquitous in nature, and they are frequently considered as contaminants. Paenibacillus alvei is a spore forming bacterium that swarms vigorously on routine culture media. P. alvei has been reported as the cause of human infections in only a few cases. We report a case of cellulitis caused by P. alvei on right leg in an immunocompetent 62-year-old man.
