an epidemiological study of listeriosis in dairy cattle

1.29-18.22) whereas straw bedding in houses other than cubicles and loose yards was
associated with a decreased risk of disease (OR 0.0, CL 0.0-1.05) (Table 3 18).
(v) General management:
a) Cases of Listeriosis in other animals: Reporting cases of Listeriosis in beef cattle
(OR 51.4, CL 12.63-243.04) and in sheep (OR 3.94, CL 1.55-9.71) was associated with
an increased risk of reporting silage eye cases (Table 3. 18).
b) Vaccine use: Vaccinating animals against Leptospirosis was associated with an
increased risk of disease (OR 1.77, CL 1.01-3.10) (Table 3. 18).
c) Mole hills: The presence of mole hills in fields was associated with an increased risk
of reporting silage eye (OR 1.80, CL 1.01-3.23) (Table 3. 18).
