“…Gemella species, including Gemella morbillorum, a microaerophilic Gram-positive coccus, are part of the normal fl ora of the human oropharynx, upper respiratory, urogenital and gastrointestinal tract rarely causing human infection. Although uncommonly pathogenic, they have been implicated in a variety of human infections, some of them with serious consequences, most notably infective endocarditis [1][2][3][4][5][6][7] . Dental instrumentation appears to be the usual source of infection 1 .…”

-Gemella morbillorum, a commensal of the oropharynx, upper respiratory, urogenital and gastrointestinal tract is rarely associated with infections in humans. However, an increasing number of infectious processes in different locations have been reported. Cerebral abscesses caused by these bacteria are extremely uncommon with only four cases previously described in the literature. We present the case of a cerebellar abscess by Gemella morbillorum in a 50 years-old man with inter-atrial communication dealt by surgical excision and antimicrobial therapy.KEY WORDS: cerebellar abscess, inter-atrial communication, Gemella.

“…For many years Enterococci species believed to be harmless and considered medically unimportant, because they produce bacteriocins, and they have been used in food industry as starter for dairy products and probiotic [ 1 ], but recently Enterococci have been emerged as an important nosocomial pathogens and are among the most frequently isolated organisms in hospital-acquired infections [ 2 ]. At present Enterococci is known as important nosocomial infections such as endocarditis [ 3 ] bacteremia [ 3 , 4 ] and urinary tract infections [ 5 ]. The majority of enterococcal infections are caused by E. faecalis .…”

Enterococci rank among leading cause of nosocomial bacteremia and urinary tract infection in hospital and community acquired infections. Several traits that may contribute to enhanced virulence have been identified in Enterococci. Extracellular surface protein (Esp) is a virulence factor that contributes in biofilm formation and resistance to environmental stresses. In this study we aimed to determine occurrence of esp in E. faecium and E. faecalis isolates isolated from urinary tract infections and to investigate whether there is any correlation between presence of esp and antibiotic resistance. One hundred and sixty six isolates were collected from patients with UTI and after identification by biochemical and PCR, antibiotic resistances were examined. The presence of esp was investigated by primer-specific PCR. 43.3% of isolates identified as E. faecium and 56.7% as E. faecalis. The esp gene was found in 76.1% of E. faecium isolates and 77.9% of E. faecalis isolate. There were significant correlation between esp positive E. faecium and resistance to Vancomycin (p<0.01), also in E.faecalis we found correlation between esp positive and resistance to Ampicillin, Chloramphenicol and Tetracycline (p<0.01, p<0.01, p<0.01 respectively). Occurrence of esp in our isolates from urinary tract infection was high that indicates importance of this gene in urinary tract infections and shows importance of ability to forming biofilm and hydrophobicity of surface of Enterococci for causing urinary infection by Enterococci. Also, our finding showed significant correlation between resistance to antibiotics and presence of esp in Enterococci.

“…In our case, the source of bacteremia was not found. There is a tendency to involve normal left-sided valves as in our case (2,(6)(7)(8)10). S. pyogenes endocarditis in intravenous drug addicts, similar to Staphylococcus aureus, involves mainly right-sided valves and mortality is low (2).…”

Although group A β-hemolytic streptococcus is an uncommon cause of infective endocarditis, an increase in the incidence of invasive group A streptococcus infections including bacteremia has been reported in the last two decades. Herein we report Streptococcus pyogenes endocarditis in a previously healthy adult patient who was hospitalized to investigate the etiology of fever. Because of a suspicion of a new vegetation appeared in the second (aortic) valve in the 14 th day of high dose penicillin G treatment, the mitral and aortic valves were replaced by mechanical prosthesis on the 22 nd day of treatment. He was discharged from hospital after the 6 week course of antibiotic treatment.
