Gastrointestinal parasitism is a common problem in pets. Intestinal parasites are found worldwide. The parasites can be wormlike (e.g., stomach worms, roundworms, hookworms, tapeworms) or one-celled (e.g., Isospora, Giardia, Toxoplasma) organisms. The signs associated with parasite infections are fairly nonspecific.
Most dogs become infected by ingesting infective agents, eggs, Giardia duodenalis cysts, or larvae in a contaminated environment. Dog parks play an important role in the well-being of your pet however, there is an increased risk for exposure to intestinal parasites. Cats show prevalence rates as high as 45 percent.
Undetected infections may become clinically apparent, and untreated pets may shed parasites that contaminate the environment, presenting a threat to animals and humans. Children and immunocompromised individuals are at the greatest risk. One Health indicates that routine monitoring and appropriate parasiticide treatments are crucial for pet health. Frequent fecal examination with appropriate and combined diagnostic techniques is important for pets of all ages.
Parasite reinfections are very common, but can be prevented. Parasite control begins with good sanitation procedures. This includes daily removal of feces; washing the litter box with a disinfectant (e.g., diluted household bleach) on a regular basis; avoiding overcrowded conditions; avoiding diets with raw meats; and controlling intermediate hosts (fleas, ticks, and rodents). Good parasite control is the key to a healthier pet.
