Members of the genus Myroides are aerobic Gram-negative bacteria that are common in environmental sources, but are not components of the normal human microflora. Myroides organisms behave as low-grade opportunistic pathogens, causing infections in severely immunocompromised patients and rarely, in immunocompetent hosts. A case of Myroides odoratimimus cellulitis following a pig bite in an immunocompetent child is presented, and the medical literature on Myroides spp. soft tissue infections is reviewed.

Primary peritonitis is a rare infection in healthy children, mainly affecting patients with underlying medical disorders. We report a case of primary pneumococcal peritonitis in an immunocompetent 3‑year‑old boy. The analysis and diagnosis was made at laparotomy and cultures of the intra‑abdominal pus yielded Streptococcus pneumoniae. Timely antibiotic treatment administered resulted in complete resolution of the infection.
