Do Patterns of Bacterial Diversity along Salinity Gradients Differ from Those Observed for Macroorganisms?
It is widely accepted that biodiversity is lower in more extreme environments. In this study, we sought to determine whether this trend, well documented for macroorganisms, also holds at the microbial level for bacteria. We used denaturing gradient gel electrophoresis (DGGE) with phylum-specific primers to quantify the taxon richness (i.e., the DGGE band numbers) of the bacterioplankton communi...
متن کاملAmino acids of the cholera toxin from differ from those of strain O 1 (
The isolates of Vibrio cholerae (Vc) non-O1 from the Sudanese outbreak in 1968 produce an enterotoxin similar to cholera toxin (CT) of Vc O1. However, we have observed that the subunit B of CT purified from a Sudanese isolate (strain $7) was a larger oligomer than that of Vc O1 (Yamamoto et al., 1983). This larger oligomer formation was suggested to be due to difference in the subunit B from CT...
متن کاملSphingosine forms channels in membranes that differ greatly from those formed by ceramide.
Ceramide channels formed in the outer membrane of mitochondria have been proposed to be the pathways by which proapoptotic proteins are released from mitochondria during the early stages of apoptosis. We report that sphingosine also forms channels in membranes, but these differ greatly from the large oligomeric barrel-stave channels formed by ceramide. Sphingosine channels have short open lifet...
متن کاملMotile activities of Dictyostelium discoideum differ from those in Protista or vertebrate animal cells.
Cell movement in the amoebae Dictyostelium discoideum has been examined in media differing in monovalent cation concentration (i.e. Na+ and K+). Under isotonic or even slightly hypertonic conditions, the cells move equally well in solutions in which either potassium or sodium ions dominate. However, in strongly hypertonic solutions the amoebae showed motility in a 2% potassium chloride solution...
متن کاملDo patients with recurrent episodes of campylobacteriosis differ from those with a single disease event?
BACKGROUND Although Campylobacter is the leading cause of reported bacterial gastro-enteritis in industrialized countries, little is known on its recurrence. The objective of this study is to describe the risk and the patient characteristics of recurrent episodes of human campylobacteriosis reported in Quebec. METHODS Laboratory-confirmed cases of campylobacteriosis reported in the province o...
