Abstract
Streptococcus equi subsp. zooepidemicus (S. zooepidemicus)
is one of the most common pathogens of endometritis in intensive donkey
farms. In order to investigate the molecular
epidemiological characteristics of S.
zooepidemicus isolates associated with endometritis in
intensive donkey breeding farms in China, isolates (n=40) from 8
small and medium-sized breeding farms were selected for multilocus sequence
typing analysis. Results revealed that 4 sequence types (STs) were identified,
ST360, ST380, ST413, and
a novel genotype ST-novel, and these were genetically distant from each other,
which suggested that S. zooepidemicus strains caused endometritis in
intensive donkey farms possessed high genetic diversity and were lack of
genotype specificity. The result of present study contributed to the
understanding of the molecular epidemiological characteristics of S.
zooepidemicus isolates.
