Background

Mixta calida was originally isolated from powdered infant formula, and in 2010 was placed in the genus Pantoea.^[3] In 2018, the species was reclassified into the novel genus, Mixta.^[1] The species name is derived from Latin calida (warm, hot), referring to the species' ability to grow well at 44 °C.^[3]

Research on infections in humans is limited, but Mixta calida has been reported to cause implantable cardioverter defibrillator-related infection, postsurgical meningitis, and bacteremia.^[4]
