In a companion paper, we requested the Judicial Commission to correct the type strain of from ATCC 15468 to NCMB 74 (=ATCC 23309). Correction of this error on the 1980 Approved Lists by an Opinion of the Judicial Commission will remove the status of the name as a junior objective synonym of . This is important because the scientific community continues to use the name almost exclusively instead of .

We request that the type strain designations for and subsp. be corrected from ATCC 15468 to NCMB 74.

Performance-limiting scattering processes have been measured directly which provide new insight into the electronic conduction mechanisms within the nanowires. Results demonstrate a transition from 3-dimensional (3D) to 2D and then 1D as the nanowire mean widths are reduced from 12 to 4 nm.

Phase-matching wavelengths and conversion efficiencies were determined for several quasi-phase-matching periods using 1.9 ps pulses.

Comparative 16S rRNA gene sequence analysis suggested that strains of Achromobacter groups B and E belong to P. phragmitetus (similarity levels were higher than 99 %).

Comparative 16S rRNA gene sequence analysis confirmed that group EF-4a and EF-4b belong to the genus Neisseria with Neisseria canis and Neisseria dentiae as the nearest phylogenetic neighbours. DNA-DNA hybridizations and biochemical analyses demonstrated that isolates of group EF-4a and EF-4b represent two novel species within this sublineage of the genus Neisseria.

Phenotypic and phylogenetic studies were performed on four Campylobacter-like organisms recovered from three seals and a porpoise. Comparative 16S rRNA gene sequencing studies demonstrated that the organisms represent a hitherto unknown subline within the genus Campylobacter, associated with a subcluster containing Campylobacter jejuni, Campylobacter coli and Campylobacter lari. DNA-DNA hybridization studies confirmed that the bacteria belonged to a single species, for which the name Campylobacter insulaenigrae sp.

In this paper minimal standards for the description of new genera and cultivable species in the family Flavobacteriaceae are proposed in accordance with Recommendation 30b of the Bacteriological Code (1990 Revision). In addition to specified phenotypic characteristics, the description of new species should be based on DNA-DNA hybridization data, and the placement of new taxa should be consistent with phylogenetic data derived from 16S rRNA sequencing. An emended description of the family is also proposed as several new taxa have been described since 1996.
