Two Cases of Liver Abscess Caused by Group G beta-Hemolytic Streptococcus / 감염

ABSTRACT

Group G beta-hemolytic Streptococcus is a normal flora of skin, pharynx, female genital tract, and intestine. Group G beta-hemolytic Streptococcus has been reported to cause a variety of human infections, such as pharyngitis, soft tissue infection, arthritis, osteomyelitis, respiratory infection, endocarditis, meningitis, puerperal infection, neonatal sepsis and peritonitis. But liver abscess caused by group G beta-hemolytic Streptococcus has not been reported to date. We report two cases of liver abscess caused by group G beta-hemolytic Streptococcus. One patient with underlying neurofibromatosis presented with fever and diarrhea; the other patient presented with fever and pain on the right upper quadrant of abdomen. Hepatic abscess was diagnosed by computerized tomography and confirmed by percutaneous needle aspiration. Cultures of pus obtained by aspiration revealed group G beta-hemolytic Streptococcus, which were susceptible all tested antibiotics, including penicillin.
