ABSTRACT Potential
risk factors for
Ureaplasma diversum in the vaginal
mucus of 1,238
dairy cows were included in a multivariate
logistic regression model, based on the
cow level (i.e., granular
vulvovaginitis [+GVV], yearly
milk production [4500 kg or more],
pregnancy, predominance of
Bos taurus [+
Bos Taurus], score of corporal condition [at least 2.5], concomitant positivity for
Escherichia coli [+E.coli]), and
farm level i.e., milking room
hygiene (-Milking room), dunghill
location, and replacement
female).
Ureaplasma diversum was present in 41.1% of the samples. Independent
risk factors for U. diversum were +GVV (
odds ratio [OR], 1.31); +
Mycoplasma spp (OR, 5.67); yearly
milk production (4500 kg or more) (OR, 1.99); +
Bos taurus (OR, 1.68); +E. coli (OR, 4.96); -milking room (OR, 2.31); and replacement
females (OR, 1.89).
Ureaplasma diversum vaginal colonization was strongly associated with
Mycoplasma spp., E. coli, and number of pregnant
cows.
