Genetic Variation within a Lotic Population of Janthinobacterium lividum.
An understanding of the genetic variation within and between populations should allow scientists to address many problems, including those associated with endangered species and the release of genetically modified organisms into the environment. With respect to microorganisms, the release of genetically engineered microorganisms is likely to increase dramatically given the current growth in the...
متن کاملLactococcus garvieae in wild Red Sea wrasse Coris aygula (Labridae).
Lactococcus garvieae infection in wild wrasse Coris aygula is reported, and the serological and molecular characteristics of the isolate are described. This is the first evidence of the presence of this pathogen in the Red Sea, and it follows the recent diagnosis of Mycobacterium marinum and Streptococcus iniae in wild fish from the same region. Whether all 3 pathogens are strains endemic to th...
متن کاملDiversity and association of psychrophilic bacteria in Antarctic sea ice.
The bacterial populations associated with sea ice sampled from Antarctic coastal areas were investigated by use of a phenotypic approach and a phylogenetic approach based on genes encoding 16S rRNA (16S rDNA). The diversity of bacteria associated with sea ice was also compared with the bacterial diversity of seawater underlying sea ice. Psychrophilic (optimal growth temperature, < or = 15 degre...
متن کاملEvolutionary relationships of cultivated psychrophilic and barophilic deep-sea bacteria.
Evolutionary relationships of cultivated barophilic bacteria were determined. All psychrophilic and barophilic isolates were affiliated with one of five genera of the gamma subdivision of the class Proteobacteria ((gamma)-Proteobacteria): Shewanella, Photobacterium, Colwellia, Moritella, and a new group containing strain CNPT3. The data indicate that the barophilic phenotype has evolved indepen...
متن کاملGrowth of psychrophilic bacteria.
On the basis of the temperature range in which growth can occur, bacteria are usually divided into 3 groups, namely: thermophiles, mesophiles, and psychrophiles (sometimes called cryophiles or rhigophiles). Thermophiles have temperature optima (generally quite close to temperature maxima) 10 to 25 degrees above the temperature optima of mesophiles. Thermophiles and mesophiles are easily disting...
