Interspecies communication in bacteria.
Until recently, bacteria were considered to live rather asocial, reclusive lives. New research shows that, in fact, bacteria have elaborate chemical signaling systems that enable them to communicate within and between species. One signal, termed AI-2, appears to be universal and facilitates interspecies communication. Many processes, including virulence factor production, biofilm formation, and...
متن کاملInterspecies Sex and Taste
Different species of fruit flies share habitats but are believed to mate with each other only rarely. In this issue, Fan et al. show that interspecies mating is inhibited by the taste receptor Gr32a (Gustatory receptor 32a) and a neural circuit in which it functions.
متن کاملInterspecies transplacement of mitochondria
Protoplasts of a respiration-deficient rho strain of Saccharomyces cerevisiae were incubated with mitochondria isolated from various respiration-competent yeast species under conditions enabling transplacement of mitochondria. Respiration-competent cybrids were selected by plating the protoplasts on agar media containing a non-fermentable energy source. The resulting cybrids contained nuclear D...
متن کاملInterspecies Communication and Periodontal Disease
More than 500 bacterial strains may be found in dental plaque. In the beginning, the emphasis was laid on the isolation of bacteria in pure culture to define their properties. However, now, it has been well established that in nature the bacteria exist as a member of polymicrobial community or consortium of interacting species. Interactions among human oral bacteria are integral to the developm...
متن کاملInterspecies Communication In Oral Biofilm
Oral cavity contains large numbers of microorganisms. Dental plaque is composed of bacteria in a matrix of salivary glycoproteins and extracellular polysaccharides which displays extensive interactions while forming biofilm structures, carrying out physiological functions, and inducing microbial pathogenesis. Our emerging view of the microbial world is one in which individual bacteria exert the...
