The incidence of acute episodes of intestinal infectious diseases in the United States was estimated through analysis of community-based studies and national interview surveys. Their differing results were reconciled by adjusting the study population age distributions in the community-based studies, by excluding those cases that also showed respiratory(More)
Serum samples taken from women with toxic-shock syndrome (TSS) and from women without a history of TSS were examined for the presence of antibodies to toxic-shock-syndrome toxin (TST). Serum samples from 38 women with TSS and from 70 women with no history of TSS were analyzed by radioimmunoassay (RIA) and by an enzyme-linked immunoadsorbent assay (ELISA).(More)
OBJECTIVE --To describe the epidemiology of foodborne disease outbreaks in nursing homes and to identify where preventive efforts might be focused. DATA SOURCES --Reports by state and local health departments of foodborne disease outbreaks occurring from January 1, 1975, through December 31, 1987. STUDY SELECTION --Foodborne disease outbreaks reported(More)
The ChemCam instrument, which provides insight into martian soil chemistry at the submillimeter scale, identified two principal soil types along the Curiosity rover traverse: a fine-grained mafic type and a locally derived, coarse-grained felsic type. The mafic soil component is representative of widespread martian soils and is similar in composition to the(More)
[1] Iron fertilization of macronutrient-rich but biologically unproductive ocean waters has been proposed for sequestering anthropogenic carbon dioxide (CO 2). The first carbon export measurements in the Southern Ocean (SO) during the recent SO-Iron Experiment (SOFeX) yielded $900 t C exported per 1.26 t Fe added. This allows the first realistic, data-based(More)
Foodborne disease has become a contemporary issue. Several large, well-publicized outbreaks of foodborne disease have heightened public awareness that harmful microorganisms may be present in food and that chronic as well as acute disease may be caused by foodborne microbes. The field of food microbiology has likewise experienced a resurgence of interest.(More)
