Globicatella sanguinis Osteomyelitis and Bacteremia: Review of an Emerging Human Pathogen with an Expanding Spectrum of Disease. Open Forum Infect Dis 2017; 4:ofw277.

Abstract
Background Globicatella sanguinis is an uncommon pathogen that may be misdiagnosed as viridans group streptococci. We review the literature of Globicatella and report 2 clinical cases in which catalase-negative Gram-positive cocci resembling viridans group streptococci with elevated minimum inhibitory concentrations (MICs) to ceftriaxone were inconsistently identified phenotypically, with further molecular characterization and ultimate identification of G sanguinis. Methods Two clinical strains (from 2 obese women; 1 with a prosthetic hip infection and the other with bacteremia) were analyzed with standard identification methods, followed by matrix-assisted laser desorption ionization time-of-flight mass spectrometry, 16S recombinant ribonucleic acid (rRNA), and sodA polymerase chain reaction (PCR). The existing medical literature on Globicatella also was reviewed. Results Standard phenotypic methods failed to consistently identify the isolates. 16S PCR yielded sequences that confirmed Globicatella species. sodA sequencing provided species-level identification of G sanguinis. The review of literature reveals G sanguinis as an increasingly reported cause of infections of the urine, meninges, and blood. To our knowledge, this is the first reported case of an orthopedic infection caused by Globicatella sanguinis. A review of the 37 known cases of G sanguinis infection revealed that 83% of patients are female, and 89% are at the extremes of age (<5 or >65 years). Conclusions Globicatella sanguinis, an uncommon pathogen with elevated minimum inhibitory concentrations to third-generation cephalosporins, is difficult to identify by phenotypic methods and typically causes infections in females at the extremes of age. It may colonize skin or mucosal surfaces. Advanced molecular techniques utilizing 16S rRNA with sodA PCR accurately identify G sanguinis.

Abstract
Globicatella sanguinis is a gram-positive coccus, resembling non-haemolytic streptococci. The organism has been isolated infrequently from normally sterile sites of humans. Three isolates obtained by blood culture could not be identified by Rapid 32 ID Strep, but partial sequencing of the 16S rRNA gene revealed the identity of the isolated bacteria, and supplementary biochemical tests confirmed the species identification. The cases histories illustrate the dilemma of finding relevant, newly recognized, opportunistic pathogens and the identification achievement (s) that can be obtained by using new molecular diagnostics.

Abstract
Globicatella sanguinis is a very rare isolate in clinical samples. We present a case of meningitis in a 69-year-old female patient after implantation of an external left ventricular drainage due to a hydrocephalus. She recovered after antibiotic treatment with ceftriaxone.

Abstract
BACKGROUND Globicatella are streptococcus-like organisms that have been rarely isolated from clinical specimens. Their epidemiology and clinical significance remain largely unknown. AIMS To describe two cases of Globicatella bacteraemia identified by 16S ribosomal RNA (rRNA) gene sequencing. METHODS Two unidentified streptococcus-like bacteria isolated from blood cultures of patients were subject to 16S rRNA gene sequencing. RESULTS Two cases of Globicatella bacteraemia were identified by 16S rRNA gene sequencing. In the first case, a gram positive coccus was isolated from the blood culture of an 80 year old woman with diabetes mellitus and nosocomial sepsis, who died the day after developing the bacteraemia. The bacterium was unidentified by conventional phenotypic tests, the Vitek (gram positive identification) and the ATB expression (ID32 Strep) systems. In the second case, a similar bacterium was isolated from the blood culture of a 92 year old woman with polymicrobial acute pyelonephritis complicated by septic shock, who subsequently recovered after antibiotic treatment. 16S rRNA gene sequencing of the two isolates showed 0.5% nucleotide difference from that of G. sulfidifaciens and 0.7% nucleotide difference from that of G. sanguinis, indicating that they were Globicatella species. CONCLUSIONS Because Globicatella is rarely encountered in clinical microbiology laboratories, it may have been overlooked or misidentified in these cases. 16S rRNA gene sequencing is a useful tool to better characterise the epidemiology and clinical significance of Globicatella.

Abstract
We describe systemic infection by Weissella confusa in a mona monkey (Cercopithecus mona) on the basis of microbiologic, molecular genetic, and histologic data. The same strain of W. confusa, as determined by pulsed-field gel electrophoresis, was isolated in pure culture from the primate’s brain, liver, spleen, and intestine. Histologic lesions showed inflammatory infiltrates mainly composed of neutrophils, indicating an acute septicemic process.
