| Abstract: | Natural and experimental infections of cats with Dirofilaria immitis have been reported. Experimental infections of D. immitis in cats with the subsequent detection of microfilaremia and immediate skin hypersensitivity to antigen to D. immitis were produced. Cutaneous nodules and chylothorax were also detected in some infected cats. Adult worm recoveries were low and dead worms were found in some cats indicating the unsuitability of the cat as a host for D. immitis. However, one successful mosquito passager of D. immitis from a cat to a dog was accomplished. |
