We reviewed cases of Providencia stuartii bacteremia at a large community teaching hospital during a 12-year period (1981 to 1992). None of the infections were hospital-acquired. Of the 49 patients, 47 (96%) came from a nursing home, and 45 (92%) had…
Most cases of Yersinia enterocolitica manifest with symptoms of enterocolitis, such as diarrhoea, fever and abdominal pain. Y. enterocolitica is a very rare cause of pneumonia, and usually occurs in immunocompromised patients. We report a case of…
We conducted a multicenter, retrospective cohort study of patients with Streptococcus pneumoniae bacteremia to determine factors associated with antibiotic resistance and mortality. Risk factors were identified using multivariate logistic regression.…
We report three cases of group B streptococcal endocarditis of the tricuspid valve. Two patients were intravenous drug abusers. In the literature review, and including our cases, ten patients had group B streptococcal endocarditis of the tricuspid…
Beta hemolytic streptococcus group G is increasingly being recognized as a cause of serious infections. We describe a patient with group G streptococcus septic arthritis of the right knee and osteomyelitis of the proximal tibia. Clinical details of…
The Streptococcus pneumoniae (SP) urinary antigen (UAg) test is a commonly used assay. The purpose cif this study was to evaluate the test's actual performance in the clinical setting and determine the effects of renal function, grade of bacteremia,…
Patients with Proteus mirabilis bacteremia at a large community teaching hospital during a 13-year period (1980-1992) were retrospectively reviewed. There were 176 patients whereof 44 (25%) had polymicrobial bacteremia. The median age of patients was…
Introduction As part of an institutional review board-approved quality improvement project reviewing 10 years of experience (2009-2018) with Pseudomonas aeruginosa bacteremia (PAB) at our institution, we identified 15 patients with recurrent…
Staphylococcus epidermidis septicemia from a urinary source is rare. Two male patients had septicemic shock caused by S epidermidis urinary tract infection. Both patients had recently had indwelling urethral catheterization during severe illness.…
Staphylococcus lugdunensis is a coagulase-negative Staphylococcus capable of causing infective endocarditis on native as well as prosthetic valves and implanted cardiac devices. It causes acute disease clinically indistinguishable from that caused by…
Background: The clinical diagnosis of infective endocarditis due to Staphylococcus aureus can be difficult, and many patients with this disease are only diagnosed post mortem. There are few published reports of large series of patients with S aureus…
Introduction Advanced phenotypic, genomic, and proteomic laboratory techniques have recently modified Streptococcus bovis group (SBG) nomenclature. We wished to determine if physicians continue to recognize the importance of SBG and its association…
BackgroundStreptococcus pyogenes causes pharyngitis, tonsillitis, cellulitis, and less frequently other clinical syndromes. It is infrequently included in the differential diagnosis of other infectious illnesses. Methods We reviewed the medical…
