Peritonitis is a major complication of peritoneal dialysis (PD) and remains the most common cause of PD failure. Micrococci are catalase-positive, coagulase-negative, and gram-positive cocci that are spherical, often found in tetrad, and belong to the family Micrococcaceae. Micrococcus species are commonly found in the environment, and it is now recognized that Micrococcus species can be opportunistic pathogens in immunocompromised patients. The only consistent predisposing factor for Micrococcus infection is an immunocompromised state. We report three cases of Micrococcus PD peritonitis. Improper practice of PD may have been the causative factor. Although Micrococcus species are low-virulence pathogens, infection could result in refractory peritonitis and subsequent PD failure. Intraperitoneal administration of vancomycin for at least 2 weeks is recommended for Micrococcus peritonitis.
