The ability to recover bacteria from frozen culture specimens has important implications. The purpose of this study was to validate the utility of frozen specimens for recovery of several gram-positive and gram-negative bacterial species by culture. Results demonstrate that 98% of 250 bacterial isolates identified on initial culture were subsequently(More)
This review focuses on the epidemiology of human African trypanosomiasis: why it occurs in humans, the current methods of surveillance, and the drugs available to treat it. Emphasis is placed on the identification of human-infective trypanosomes by the blood incubation infectivity test. This test distinguishes between trypanosomes that are non-infective for(More)

African trypanosomes are lipid auxotrophs that live in the bloodstream of their human and animal hosts. Trypanosomes require lipoproteins in addition to other serum components in order to multiply under axenic culture conditions. Delipidation of the lipoproteins abrogates their capacity to support trypanosome growth. Both major classes of serum(More)
Chronic erosive gastritis is a gastric mucosal lesion characterized by multiple, small, sessile elevations with central erosions. Symptoms typically resemble those in peptic ulcer disease. The elevations may persist and appear as sessile polyps after the erosions heal and symptoms resolve with therapy. Adenomatous transformation is reported in a patient(More)
