Molecular comparisons of freshwater and marine isolates of the same morphospecies of heterotrophic flagellates

Article Abstract:

The intraspecific diversity of 10 morphospecies of heterotrophic flagellates was analyzed and the strains were isolated from marine and freshwater sites as well as soil and groundwater. It showed that freshwater lineages were not able to colonize marine environments and marine lineages were not able to colonize freshwater environments for a long time.

Multiplex assay based on single-nucleotide polymorphisms for rapid identification of Brucella isolates at the species level

Article Abstract:

A multiplex assay is developed based on the species-defining single-nucleotide (SNPs) that have offered an alternative approach for identifying Brucella isolates at the species level. The assay has overcome the subjectivity associated with biotyping with an approach that is straightforward and has advantages in terms of speed.

Assessment of an enterovirus sewage surveillance system by comparison of clinical isolates with sewage isolates from Milwaukee, Wisconsin, collected August 1994 to December 2002

Article Abstract:

The quantity and serotypes of enteroviruses (EVs) in the influent of a local sewage treatment plant were compared to local clinical EV cases to determine if testing of sewage is adequate for an EV surveillance system. Annual peaks of both sewage EV titers and clinical cases occurred in late summer or early fall.
