Infectious disease patterns in the Waorani, an isolated Amerindian population.

The Waorani Indians of eastern Ecuador provide a unique opportunity for studying exposure of an isolated human population to various infectious disease agents. Using serologic tests to determine antibody prevalence, skin test data, and stool examination for parasites, we have been able to construct a profile of infectious diseases which are endemic, and others which have been introduced into the Waorani population. These findings are compared with similar data reported from elsewhere in the Amazon. Serologic studies demonstrating the presence of antibody to measles and poliovirus type 3 after vaccination indicate that the Waorani respond normally to viral challenge with these agents. The question of genetic inability among aboriginal Amerindians to respond to viral agents is discussed. Finally, general recommendations are made regarding the future health care of the Waorani.

Phleomycin-stimulated degradation of deoxyribonucleic acid in Escherichia coli.

Phleomycin stimulates the degradation of DNA by energy-dependent endonuclease and exonuclease reactions in Escherichia coli rec(+) cells and in recB(-) and recC(-) cells that lack an adenosine triphosphate-dependent nuclease functioning in the repair of ultraviolet (UV) lesions. Exonuclease activity is blocked in T4 phage-infected cells. The endonuclease reaction produces 10(7)-dalton segments resembling those produced in colicin E2-treated cells. These differ from the random-sized segments produced in UV-irradiated cells, or the 10(6)-dalton segments made in T4 phage-infected cells. A mutant selected for phleomycin tolerance is cross-tolerant to colicin E2, and some mutants selected for colicin E2 tolerance are cross-tolerant to phleomycin. On the basis of these cross-tolerances and the similarities between the effects of phleomycin and E2-stimulated nucleases, the suggestion is made that both agents may stimulate the same nuclease reactions in E. coli cells.

Nutrition information sources.

Medical personnel and medical librarians may tend to think of nutrition in medical terms and to forget its interdisciplinary aspects. For this reason, it is desirable for medical librarians to become familiar with a variety of sources of information on the composition of foods, nutrient values, food additives, and food protection. Many of these are government publications from such agencies as the U.S. Department of Agriculture, the National Research Council, and the Food and Agriculture Organization. Less familiar sources include nutrition materials from state agricultural experiment stations and extension services and important data published in a wide range of scientific or agricultural journals, which may be located through Nutrition Abstracts and Reviews, Food Science and Technology Abstracts, and the Bibliography of Agriculture. Sources of current information on nutrition research in progress include the Department of Agriculture's Current Research Information System (CRIS) and selective listings from the Smith-sonian Information Exchange.
