Isolated severe thunderstorms with a potential for large hail and wind damage are possible today across parts of the southern Plains into the northern Ozarks. Marginally severe thunderstorms with strong wind gusts and hail are also possible from the Ohio Valley into the central and northern Appalachians. Chehalis-Centralia Airport (KCLS)
A pilus (Latin for 'hair'; plural: pili) is a hairlike appendage found on the surface of many bacteria. The terms pilus and fimbria (Latin for 'fringe'; plural: fimbriae) can be used interchangeably, although some researchers reserve the term pilus for the appendage required for bacterial conjugation.ovement produced by type IV pili is typically jerky, and so it is called twitching motility, as distinct from other forms of bacterial motility, such as motility produced by flagella. However, some bacteria, for example Myxococcus xanthus, exhibit gliding motility.
1 a hair or hairlike structure. 2 (in microbiology) a fine filamentous appendage found on certain bacteria and similar to flagellum except that it is shorter, straighter, and found in greater quantities in the organism. Pili consist solely of protein and are associated with antigenic properties of the cell surface.here are two kinds of pili: (a) a larger form that is hollow and found on male bacterial cells only; it is used in bacterial cell conjugation, and (b) a smaller form which is of major significance in adherence of bacterial cells to epithelial surfaces such as the intestinal mucosa or mammary gland epithelium.
