dc.description.abstractThe study was conducted with the following objectives: (1) to identify the microfilaria in the experimental dogs; (2) to determine the incidence rate of canine dirofilariasis in the selected municipalities of La Union; (3) to determine the incidence rate of canine dirofilariasis in relation to municipal categories; (3.1) to determine the significant differences in the incidence rate of canine dirofilariasis among the four municipal categories; (4) to determine the incidence rate of canine dirofilariasis in relation to breeds of dogs; and (4.1) to determine the significant differences in the incidence rate of canine dirofilariasis between breeds. This study was conducted in six selected municipalities of La Union from the months of November 2007 to January 2008. Two hundred (200) dogs which were classified into pure breed and mongrel regardless of sex and above six months of age were used in the study. Blood was collected aseptically from each test animal and subjected to Modified Knottā€™s Method to test the presence of microfilaria. To determine the presence of significant differences, Analysis of Variance and t-Test were used in the study. On the other hand, microfilaria of Dirofilaria immitis occurred in pure breed dogs in Agoo, and it occurred in mongrel dogs in Bacnotan and San Juan. Incidence rate of Dirofilaria immitis in selected municipalities in La Union was two percent (2.00%). Partially urban municipalities showed six percent (6.00%) incidence rate in dirofilariasis while urban municipalities registered 1.54% but significant differences were not observed. Both pure breeds and mongrel have equal incidence rates.
