Résumé
Group C Streptococcus (GCS) and Group G Streptococcus (GGS) distinctly differ from other Streptococcus in biochemical reactions, hemolytic properties, host species, and clinical characteristics.GCS and GGS are common colonizers of the skin, throat and female genitourinary tract of human body.The classification of GCS and GGS is complex and has been continuously corrected and revised over the past few decades.The outbreak of GCS and GGS infections mostly likely arises from environmental factors.GCS and GGS have similar pathogenicity, bacterial resistance characteristics, and clinical characteristics to group A Streptococcus.They can lead to various invasive infections, and Penicillin is still the first choice for their treatment currently.GCS and GGS infections are more severe than other Streptococcus infections.In this article, the classification and clinical characteristics of GCS and GGS were reviewed.
Résumé
PURPOSE: To report the first case of endophthalmitis due to Streptococcus dysgalactiae after phacoemulsification and posterior chamber intraocular lens implantation in the Republic of Korea. CASE SUMMARY: A 65-year-old male was transferred because of endophthalmitis following cataract surgery. His initial visual acuity was light perception. Because inflammation of the anterior chamber and vitreous cavity progressed rapidly, we performed total pars planar vitrectomy and intraocular lens extraction in addition to administering intravitreal antibiotics and intravitreal dexamethasone injections. Streptococcus dysgalactiae was identified in samples cultured from the vitreous and anterior chamber fluid. Four days after surgery, we washed the anterior chamber and intravitreal antibiotics were again injected because of increased inflammation of the anterior chamber and vitreous. The patient was discharged 25 days after surgery but corneal neovascularization, contraction, edema, infiltration, and hypopyon remained. Visual acuity progressed to no light perception and there was shrinkage of the globe. CONCLUSIONS: Endophthalmitis due to Streptococcus dysgalactiae is very rare. We report the first case of endophthalmitis caused by Streptococcus dysgalactiae in the Republic of Korea. The prognosis for recovery was poor despite aggressive treatment.

The group G streptococcal endocarditis is a rare form of infective endocarditis when present, and it is associated with serious neurological complications. Also, endogenous endophthalmitis due to group G streptococcal endocarditis has rarely been reported, and usually leads to total loss of vision. We report a case of group G streptococcal endocarditis which presented clinically as endophthalmitis unrelated to trauma or surgery in a 85-year-old diabetic man.

Bacterial pericarditis has been recognized as a rare disease since the development of antibiotics. Usually, the disease is associated with underlying conditions or a seeding of infection elsewhere to the pericardium. Here we describe a case of group G streptococcal pericarditis as an initial presentation of colon cancer. A 52-yr-old man was admitted because of dyspnea. An electrocardiogram showed a diffuse ST-segment elevation and a two-dimensional echocardiogram showed a large amount of pericardial effusion. A pericardiocentesis was done and purulent fluid was drained. Group G streptococci was cultured in pericardial fluid. The patient was treated with antibiotics and pericardiostomy with saline irrigation. A colonoscopy revealed a small mass with moderately differentiated adenocarcinoma in rectosigmoid colon. He underwent a mucosectomy and was recovered without any complication.
