Some Respiratory Characteristics of the Blue-Green Alga, Anabaena.
In recent years there has been a considerable increase in our knowledge of the respiratory metabolism in higher plants. The lower plants, however, have received little attention. This is particularly true of the blue-green algae where the amount of available information on their respiration is almost negligible. The only known investigation has been that of EMERSON (1) who reported that respira...
متن کاملChemotaxis in Vibrio cholerae.
The ability of motile bacteria to swim toward or away from specific environmental stimuli, such as nutrients, oxygen, or light provides cells with a survival advantage, especially under nutrient-limiting conditions. This behavior, called chemotaxis, is mediated by the bacteria changing direction by briefly reversing the direction of rotation of the flagellar motors. A sophisticated signal trans...
متن کاملVibrio cholerae non-serogroup O1 cystitis.
We report a case of a patient who developed cystitis caused by non-serogroup O1 Vibrio cholerae after swimming in the Chesapeake Bay. Treatment was empirical, with complete symptomatic resolution. Genitourinary tract infections by Vibrio spp. are uncommon but should be considered when cystitis occurs after saltwater exposure in appropriate geographic regions.
متن کاملHybrid El Tor Vibrio cholerae O1, Kuwait
To the Editor: The traditional causative agent of cholera, Vibrio chol-erae O1, has 2 biotypes, classical and El Tor. The current seventh pandemic that began in 1961 and has spread to much of the world is caused by the El Tor biotype. This biotype has replaced the classical biotype responsible for the previous pandemics. The classical and El Tor biotypes are differentiated by phenotypic tests (...
متن کاملThe Vibrio cholerae O1 chromosomal integron.
Until the discovery of the Vibrio cholerae repeat (VCR), the gene capture and expression systems termed integrons had been typically associated with antibiotic-resistance gene cassettes with usually less than five genes in an array. A method is described for the cloning of the ends of large cassette arrays. Conserved restriction sites within VCRs facilitated the mapping by Southern hybridizatio...
