Abstract
The prevalence of canine parvoviral infection in three
hundred and forty nine dogs from all over Kerala including 57
clinically suspected dogs and 292 healthy and vaccinated dogs
was studied.
Among 57 clinically suspected dogs, 15.7 per cent and
19.3 per cent respectively, had CPV antigen in the faecal
samples by AGID and CIEP.
Canine parvovirus (CPV) antigen were detected in faecal
samples of 61.4 per cent of 57 clinically suspected dogs by HA
test.
EM detected CPV in one (13 per cent) of eight clinically
suspected dogs and 17 per cent of six clinically suspected
dogs had CPV in the faecal samples by IEM.
Agar gel immunodiffusion test detected canine parvoviral
antibody in seven (12.3 per cent) of clinically suspected
dogs, 14 (36.8 per cent) of 38 healthy vaccinated dogs and 17
(6.7 per cent) of 254 healthy non-vaccinated dogs.
Counterimmunoelectrophoresis (CrE) test detected CPV
antibody in 8 (14 per cent) out of 57 clinically suspected
dogs 14 (36.8 per cent) of 38 healthy vaccinated dogs and 17
(6.7 per cent) of 254 healthy non-vaccinated dogs.
Out of 349 dogs screened by HI test, 70.5 per cent dogs
had the protective level of antibody against canine parvoviral
infection. Haemagglutination inhibition test detected CPV
antibodies in 36 (63.2 per cent) of 57 clinically suspected
dogs, 37 (97.3 per cent) of 38 healthy vaccinated dogs and 173
(68.1 per cent) of 254 healthy non-vaccinated dogs.
Dot-ELISA detected CPV antibodies in 38 (66.7 per cent)
of 57 clinically suspected dogs, 37 (97.3 per .cerit ) of 38
healthy vaccinated dogs and 174 (68.5 per cent) of 254 healthy
non-vaccinated dogs.
More seropositive dogs were recorded in dogs below six
months of age. Prevalence rate observed was more in male
dogs, eventhough no significant difference was observed
between sexes. Among the breeds, German shepherd were more
affected, followed by Doberman Pinscher and non-descript.
Seasonal prevalence in the present study was higher during
April, June and July. However, no significant difference was
observed between different months.
