A Holistic Approach to Chronic Disease Prevention: Good Health and Wellness in Indian Country.

The National Center for Chronic Disease Prevention and Health Promotion at the Centers for Disease Control and Prevention funds the agency's largest investment in Indian Country, Good Health and Wellness in Indian Country. This 5-year program, launched in 2014, supports American Indian and Alaska Native communities and tribal organizations to address chronic diseases and risk factors simultaneously and in coordination. This article describes the development, funding, and implementation of the program.

DAPI staining and fluorescence microscopy techniques for phytoplasmas.

The 4',6-diamidino-2-phenylindole (DAPI) stain technique is a simple method that was developed for confirming the presence of phytoplasmas in hand-cut or freezing microtome sections of infected tissues. DAPI binds AT-rich DNA preferentially, so that phytoplasmas, localized among phloem cells, can be visualized in a fluorescence microscope. The procedure is quick, easy to use, inexpensive, and can be used as a preliminary or quantitative method to detect or quantify phytoplasma-like bodies in infected plants.

[Evaluation of trap color and position on the capture of cicadellids in Gaultheria phillyreifolia (Ericaceae) affected by phytoplasmas].

Color sticky traps are one of the main alternatives to collect insect vectors, as they are easy to handle and are inexpensive. We aimed to compare the effect of color and height of the traps on the attractiveness to potential cicadellids vectors of plant pathogens. Yellow and green colored stick traps were placed at two different heights in plant of Gaultheria phillyreifolia.
