INTESTINAL BACTERIAL FLORA AND TRANSIT TIME OF THREE NEOTROPICAL BAT SPECIES.

abstract：:Extracellular fibrils are involved in cell cohesion and cell development in Myxococcus xanthus. One group of social motility mutants, Dsp, is unable to produce extracellular fibrils; these mutants also lose the abilities to cohere and to develop. Extracellular fibrils isolated from vegetative wild-type cells and added...
