fifty dogs from different parts of Thrissur including 138
dogs presented to the Hospital and twelve stray dogs were
studied by microscopic agglutination test.
Among the 150 dogs, 49 (32.67 per cent) were
seropositive to Leptospira serovars pomona (53.06 per cent),
canicola (32.65 per cent) and icterohaemorrhagiae (14.28 per
cent) 83.33 per cent of the stray dogs were seroreacative
with agglutinins to L. serovars pomona (90 per cent) and
L. canicola (10 per cent) .
Seroprevalence recorded was higher age wise among young
dogs, upto three years of age, among the male dogs and among
non-descript and German Shepherd dogs. Monthwise prevalence
was higher during June, May and December.
DFM examination were carried out on blood samples from
23 suspicious cases of leptospirosis and 12 stray dogs, and
on urine sample from eight suspected cases. Leptospiraemia
was detected in two clinical cases (C 261 and C 11556) and
from two stray dogs (S-6 and S-10) Urine sampies were
negative for leptospires or DFM.
Culture and isolation were tried with blood sample from
23 suspected cases of leptospirosis and from 12 stray dogs,
urine sample from eight suspected cases of leptospirosis and
kidney tissue from six sacrificed stray dogs. Of these,
blood sample from stray dog 8-6 showed evidence of growth in
the medium, but leptospires could not be isolated. The
culture medium with kidney tissue from stray dog 8-6 revealed
the presence/growth of leptospires on DFM examination. But
isolation of leptospires from amongst the contaminants was
not possible on further subculture, millipore filtration or
guinea pig inoculation.
Haematological findings in the seropositive dogs were
monocytosis which was highly significant, non- significant
i~crease in the mean values of E8R, total leucocyte count and
absolute neutrophil count. A slight increase in the mean
PCV, absolute lymphocyte and eosinophil count were recorded.
Mean haemoglobin level was slightly lower in the seropositive
dogs, compared to the seronegative dogs.
On biochemical analysis, significant increase (PsO.05)
in creatinine level was recorded in the seropositive dogs.
There was increase in the mean total bilirubin, albumin and
albumin-globulin ratio in the seropositive dogs, but it was
non-significant. Mean serum total protein, globulin, serum
ALT values were lower in the seropositive group compared to
those of the seronegative group.
