Staphylococcus nepalensis sp. nov., isolated from goats of the Himalayan region.

Four coagulase-negative, novobiocin-resistant cocci, designated CW1(T), PM34, MM3 and RW78, were isolated from the respiratory tract of goats kept in the Himalayan region. The four isolates were assigned to a single species on the basis of almost identical biochemical and physiological traits, protein profiles obtained after SDS-PAGE and identical genomic fingerprints generated after enterobacterial repetitive intergenic consensus (ERIC)-PCR. Strain CW1(T) showed highest 16S rDNA sequence similarities to Staphylococcus cohnii subsp. urealyticus ATCC 49330(T), Staphylococcus saprophyticus subsp. saprophyticus ATCC 15305(T), S. cohnii subsp. cohnii ATCC 29974(T), Staphylococcus arlettae ATCC 43957(T), Staphylococcus gallinarum ATCC 35539(T), Staphylococcus succinus ATCC 700337(T) and Staphylococcus xylosus ATCC 29971(T) (99.0, 98.8, 98.8, 98.4, 98.2, 98.1 and 98.1 %, respectively), indicating its classification within the genus Staphylococcus. The polar lipid composition, fatty acid profiles, quinone systems and diagnostic cell-wall diamino acid were in agreement with the characteristics of the genus Staphylococcus. DNA-DNA hybridization with closely related Staphylococcus species suggested that strain CW1(T) represents an as-yet unrecognized species. Based on these results, a novel species of the genus Staphylococcus is described, Staphylococcus nepalensis sp. nov. The type strain is CW1(T) (=DSM 15150(T)=CCM 7045(T)) and the most dissimilar strain is PM34 (=DSM 15151=CCM 7046).
