ABSTRACT Chryseobacterium indologenes is a Gram-negative aerobic bacillus commonly found in nosocomial environments, particularly in patients with prolonged hospital stays or those requiring long-term invasive devices. It primarily affects elderly and immunocompromised individuals. This microorganism is associated with multidrug resistance, which is a crucial factor in treatment decisions. Here, we report a case of C. indologenes infection in an infant following the ingestion of milk formula diluted with untreated water.
