Massilia timonae, which was isolated for the first time in 1998 from the blood of an immunocompromised patient, is the most clinically relevant . In 2008, the species M. varians was found in a clinical isolate and, in 2012, the species M. oculi was also classified as pathogenic to humans .
Few infections with Massilia bacteria have been described in the literature. Most infections are caused by Massilia timonae and occur as co-infections or in immunosuppressed patients. Rare cases of patients without underlying conditions have also been documented. The few such cases described reveal a wide range of diseases .
Bone marrow inflammation
Infection of the inside of the eye
Massilia spp. are environmental bacteria that are primarily found in the ground, in water, in the air, and in plants. Some species were also isolated from human samples (blood, cerebrospinal fluid) .
Relevance of pathogen in transmission in endoscopy
Ear, nose, and throat: Low
Relevance for endoscope surveillance
High concern organism
Resistance to antibiotics
In studies on isolates from soil in the surroundings of poultry and cattle farms, Massilia spp. was identified as being a carrier of resistance genes to sulfonamides .
