Alkanindiges hongkongensis sp. nov. A novel Alkanindiges species isolated from a patient with parotid abscess.

A bacterium was isolated from the abscess pus of a 72-year-old patient with Warthin's tumor and parotid abscess. The cells were aerobic, non-motile, Gram-negative but difficult to be destained, non-sporulating, coccobacillus. The bacterium grew poorly on sheep blood agar and MacConkey agar as non-hemolytic colonies of 0.

Anaerospora hongkongensis gen. nov. sp. nov., a novel genus and species with ribosomal DNA operon heterogeneity isolated from an intravenous drug abuser with pseudobacteremia.

A bacterium was isolated from the blood culture of an intravenous drug abuser with pseudobacteremia. The cells were strictly anaerobic, straight or slightly curved, sporulating, Gram-negative rods. It grew on sheep blood agar as non-hemolytic, pinpoint colonies after 48 hr of incubation at 37 C in an anaerobic environment.

Bacteremia in a patient with colonic carcinoma caused by a novel Sedimentibacter species: Sedimentibacter hongkongensis sp. nov.

A bacterium was isolated from the blood culture of a 91-year-old patient with colonic carcinoma. The cells were strict anaerobic, motile, Gram-negative, sporulating, straight, or slightly curved rods. The bacterium grew on agar using the BACTEC anaerobic blood culture broth or buffered charcoal yeast extract agar as pinpoint colonies after 72 h of incubation at 37 degrees C in anaerobic conditions.

Eggerthella hongkongensis sp. nov. and eggerthella sinensis sp. nov., two novel Eggerthella species, account for half of the cases of Eggerthella bacteremia.

Eggerthella, one of the human gut flora, was rarely reported to cause bacteremia in the literature. We describe the application of 16S ribosomal RNA gene sequencing in defining the epidemiology and clinical significance of Eggerthella bacteremia during a 4-year period. Among 55 clinically significant blood culture isolates of anaerobic Gram-positive bacilli, 5 were identified as E.

Actinomyces hongkongensis sp. nov. a novel Actinomyces species isolated from a patient with pelvic actinomycosis.

A bacterium was isolated from the pus of a patient with pelvic actinomycosis. The cells were strictly anaerobic, straight, non-sporulating, Gram-positive rods. It grows on sheep blood agar as non-haemolytic, pinpoint colonies after 24 hours of incubation at 37 degrees C in anaerobic environment.

Streptococcus sinensis sp. nov., a novel species isolated from a patient with infective endocarditis.

A bacterium was isolated from the blood culture of a patient with infective endocarditis. The cells were facultative anaerobic, nonsporulating, gram-positive cocci arranged in chains. The bacterium grows on sheep blood agar as alpha-hemolytic, gray colonies of 0.
