Moraxella haemolytica sp. nov., isolated from a goat with respiratory disease
An aerobic, haemolytic, Gram-negative and rod-shaped bacterial strain ZY171148 T was isolated from the lung of a dead goat with respiratory disease in Southwest China. The strain grew at 24–39 °C, at pH 6.0–9.0 and in the presence of 0.5–2.0% (w/v) NaCl. Phylogenetic analysis of 16S rRNA gene sequen...

Summary: | An aerobic, haemolytic, Gram-negative and rod-shaped bacterial strain ZY171148
T
was isolated from the lung of a dead goat with respiratory disease in Southwest China. The strain grew at 24–39 °C, at pH 6.0–9.0 and in the presence of 0.5–2.0% (w/v) NaCl. Phylogenetic analysis of 16S rRNA gene sequences showed that the strain belongs to the genus
Moraxella
. The nucleotide sequence similarity analysis of the 16S rRNA gene showed that the strain has the highest similarity of 98.1% to
Moraxella
(
M
.)
caprae
ATCC 700019
T
. Phylogenomic analysis of 800 single-copy protein sequences indicated that the strain is a member of the genus
Moraxella
and forms a separated branch on the
Moraxella
phylogenetic tree. The strain exhibited the highest orthologous average nucleotide identity (OrthoANI) and average amino acid identity (AAI) values of 77.0 and 77.9% to

3OH (9.7%) as the predominant fatty acids and CoQ-8 as the major respiratory quinone. The strain contained phosphatidylglycerol, phosphatidylethanolamine, cardiolipin, dilysocardiolipin, monolysocardiolipin and phosphatidic acid as the major polar lipids. β-haemolysis was observed on Columbia blood agar. All results confirmed that strain ZY171148
T
represents a novel species of the genus
Moraxella
, for which the name
Moraxella haemolytica
sp. nov. is proposed, with strain ZY171148
