Reporting two novel <i>Kluyvera</i> species, <i>Kluyvera huaxiensis</i> and <i>Kluyvera chengduensis</i>, isolated from human sputa.

ABSTRACT:

Introduction

Two Gram-stain negative, facultatively anaerobic, rod-shaped, motile, and non-spore forming bacterial strains, 142053^T and 142359^T, were isolated from sputum samples obtained from different patients.

Methods

Growth of strain 142053^T and 142359^T occurred at 8-42 °C (optimum 28-37 °C), pH 5.0-9.0 (optimum 6.0-8.0) and NaCl concentrations of 0-5% (w/v) (optimum 0-4%). Comparison of 16S rRNA gene sequences showed that strain 142053^T and 142359^T exhibited high similarity to Kluyvera intermedia NBRC 102594^T (99.48%) and Kluyvera georgiana ATCC 51603^T (98.68%), respectively.
