Dirofilaria immitis

Dirofilaria immitis, commonly known as heartworm, is a parasitic roundworm that infects dogs, cats, and other animals through mosquito bites. The worms develop into adults in the heart and lungs, causing damage that can lead to respiratory issues, heart failure, and even death if untreated. The infection often shows few symptoms initially but can progress to cause fatigue, coughing, and difficulty breathing. Prevention involves regular use of veterinarian-approved medications, and treatment is available for infected animals. Controlling mosquito populations also helps reduce spread. Early detection and preventive care are crucial for maintaining an affected pet's health.
