The 1998 list - Proposed new bacterial taxa and proposed changes of bacterial names published during 1998 and considered to be of interest to medicalor veterinary bacteriology (an informational note)

In continuation of our previous efforts (Frederiksen er al. 1998/1999), we present a 1998 list of new names considered to be of interest to medical an d veterinary bacteriology. The following 45 bacterial names were published in 1998 in articles in the International Journal of Systematic Bacteriology (IJSB) (i.e. validly published) or published elsewhere and included in 199 8 on the validation lists of IJSB (i.e. validated), Our criteria for select ion of names are as previously: isolation from humans or warm-blooded anima ls with a few exceptions. IJSB 48, 1998 also brought some name corrections: (1) IJSB 48, 1073-1075, Euzeby: Taxonomic note: necessary correction of spe cific and subspecific epithets according to Rules 12c and 13b of the Intern ational Code of Nomenclature of Bacteria (1990 Revision). We encourage read ers to consult this paper. (2) Takeuchi and Hatano (IJSB 48, 739-747) proposed the unification of the genera Microbacterium and Aureobacterium with the consequence that Aureobac terium species could now be considered to belong to an emended genus Microb acterium. We found that among 125 new species/subspecies proposed in the IJSB in 1998 (i.e. validly published), 54 were based on only one strain (= 43 %). Twent y-nine new genera were proposed, and seven based on only one strain. Among 24 "medical" new species only four were based on a single strain.
