Low Prevalence

Examination of 6,880 sputum specimens from untreated patients disclosed that 3.1% were positive for mycobacteria by fluorescence microscopy, and 92.5% of these has positive cultures. There was a positive correlation between the number of organisms seen on smear and growth on culture. All specimens with positive smears and negative cultures contained rare or few acid-fast bacilli on the smear. Eighty-two percent of the specimens with positive cultures and negative smears yielded less than 25 colonies, whereas there were greater than 25 colonies from 93% of the specimens with positive smears and cultures. In a low prevalence, general hospital population, the primary acid-fast smear continued to be a reliable diagnostic tool.

The amphibian embryo offers advantages of size, availability, and ease of use with both microsurgical and molecular methods in the analysis of fundamental developmental and cell biological problems. However, conventional wisdom holds that the opacity of this embryo limits the use of methods in optical microscopy to resolve the cell motility underlying the major shape-generating processes in early development.These difficulties have been circumvented by refining and adapting several methods. First, methods of explanting and culturing tissues were developed that expose the deep, nonepithelial cells, as well as the superficial epithelial cells, to the view of the microscope. Second, low angle epi-illumination with video image processing and recording was used to follow patterns of cell movement in large populations of cells. Lastly, cells were labeled with vital, fluorescent dyes, and their behavior recorded, using low-light, fluorescence microscopy and image processing. Using these methods, the details of the cellular protrusive activity that drives the powerful convergence (narrowing)
