Most of you have probably seen some of the worms that infest dogs and cats. These include Roundworms, Hookworms, Tapeworms and Whipworms. However, there are a lot of parasites that live in your pet’s intestines that can not be seen with the visible eye and the use a microscope or antigen testing is needed to make diagnosis.
Coccidia is one of the parasites we find it frequently in puppies and kittens. It is generally not life threatening but can sometimes cause some pretty severe diarrhea. Fortunately, it is usually well controlled with a 1 or 2 week course of medication.
Another intestinal parasite that we are seeing much more frequently is Giardia. Giardia is a protozoal agent that lives in the intestines. It can cause a wide range of symptoms including vomiting and loss of appetite, but the most common symptoms of infection are diarrhea or soft stool. In order to diagnose Giardia we need to perform an antigen test on a stool sample. In a study we performed at Catoctin Veterinary Clinic recently we found that 25% of the fecal samples submitted for analysis were positive for Giardia. This is such a high proportion that we now routinely test for it when we perform a fecal analysis. One of the important issues about Giardia is that it is zoonotic, meaning it may be transmittable to people. Fortunately, recent studies show that the cat and dog Giardia species is very easily transmitted between animals but not as easily transmitted to people. Treatment is often very successful using Metronidazole or Panacur.
If you think your pet may have an intestinal worm or parasite submit a fresh fecal sample to our office. We usually have results within 24 hours and can dispense appropriate medication if we find any infection.
