Yersinia enterocolitica comprises both pathogenic and nonpathogenic members. Distinguished by biogrouping, serogrouping, and ecological distribution, commonly occurring pathogenic serobiogroups, e.g., O:3/4; O:5,27/2; O:8/1b; O:9/2, possess both chromosomal and plasmid-mediated virulence traits. Studies have revealed several (oral, blood transfusion) modes(More)
Yersinia enterocolitica, a gram-negative coccobacillus, comprises a heterogeneous group of bacterial strains recovered from animal and environmental reservoirs. The majority of human pathogenic strains are found among distinct serogroups (e.g. O:3, O:5,27, O:8, O:9) and contain both chromosome- and plasmid (60 to 75 kb)-mediated virulence factors that are(More)
Culture of the buffy coat layer of the peripheral blood of 14 AIDS patients demonstrated sustained mycobacteremia or fungemia: 11 with Mycobacterium avium-intracellulare, 2 with Cryptococcus neoformans, and one with Mycobacterium tuberculosis. The early detection of these agents prior to the onset of overt symptomatology of disseminated infection due to(More)
A 57-year-old male with a history of hypercholesterolemia and anxiety but otherwise in good health volunteered to donate the right lobe of his liver to his brother. The operation was performed uneventfully, without transfusion. Postoperatively he did well, until he developed tachycardia, profound hypotension, and coffee ground emesis on postoperative day 3.(More)
Cardiobacterium hominis, like other fastidious, opportunistic gram-negative bacilli, including Actinobacillus actinomycetemcomitans, Haemophilus aphrophilus, and Eikenella corrodens, is increasingly recognized as a cause of human disease. In this review the microbiologic and clinical features of C. hominis are discussed. The findings are based on(More)
Ten isolates of Cryptococcus neoformans recovered from individual patients with the acquired immunodeficiency syndrome (AIDS) were studied in conjunction with three other isolates from non-AIDS patients. On primary culture nine out of ten of the AIDS isolates grew as nonmucoid, dry, pasty colonies resembling those produced by "diphtheroids." One isolate(More)
Certain strains of mesophilic aeromonads (Aeromonas hydrophila, A. sorbria, and A. caviae), when grown in broth containing 0.5% glucose, undergo growth inhibition concomitant with acetate accumulation. Because these strains are nonviable after 24 h, this phenomenon is termed suicide. We investigated suicidal strains of Aeromonas species as a means of(More)
Difficulties were encountered in the recognition of a nutritionally deficient streptococcus which continued to display aberrant morphologic forms (especially bulbous swellings and filament formation) despite provision of growth factors. With isolates displaying diverse morphologic entities not characteristic of a given species, e.g., Streptobacillus(More)
During the 20 year interval from 1958 to 1978 a change in the spectrum of disease, etiology, and diagnosis of mucormycosis was observed at The Mount Sinai Hospital. Although the rhinocerebral and pulmonary forms of mucormycosis were still the most frequent forms of disease, hospital acquired cutaneous and subcutaneous infections emerged. Since 1974, 14 of(More)
