Roundworms!!

Canine and feline Roundworm!!

What is it and how does your pet get it?

Roundworms are a type of intestinal parasite commonly found in the digestive tracts of cats and dogs. This parasite can be passed from Dam to babies during nursing, across the placenta when puppies are in utero or through the ingestion of contaminated hosts or soil. Soil that has embryonated (infective) eggs or hosts that have ingested embryonated eggs pass roundworm infections on to dogs and cats when consumed. Eggs become embryonated after they have been exposed to the elements. Once the embyonated eggs are ingested they hatch out and migrate thoughout the body. The adult roundworms can be found in the small intestines.

Why have fecal examinations on your pet?

Fecal examinations are a great way to detect many intestinal parasites in your pet. Roundworms are only one of hundreds of intestinal parasites found in cats and dogs. Fecal examinations look for the microscopic eggs that are shed by mature adults. You will not always see stool changes if there is an active infection. It depends on the type of parasite, stage in the lifecycle of the parasite and number of parasites present and your pets’ sensitivity to the infection.

Why deworm puppies and kittens?

It is known that puppies and kittens can become infected in utero and puppies can become infected while nursing. If infection is present, it can affect growth and development of the puppies and kittens. Poor hair coat, pot-bellied appearance, and in severe cases death may occur. Puppies and kittens can shed eggs in the environment and then can infect other animals. When puppies and kittens are dewormed then the lifecycle can be broken.

Not only can roundworm infections affect your pet, but it is also a zoonotic disease. A zoonotic disease is something that can be transmitted between humans and animals. Dog and cat Roundworms can cause health concerns in people, particularly in children. Children tend to play in dirt that can harbour roundworm eggs and they tend to be less hygienic than adults. Health concerns in people from dog or cat roundworm can be caused by larva migrating through tissues in the body.  The parasite can travel through tissues causing inflammation. Many people may be asymptomatic for infection.

How do we prevent infection?

Regular veterinary care for your dog and cat, including fecal examinations, strategic deworming and monthly preventatives can help protect your pet. Stooping and scooping is a good practice to minimize transmission of many parasites. Eggs can be long lived in the environment. Hand washing is very important. After handling pets, playing outside and before preparing or eating food washing hands can decrease transmission to people. Do not allow your child to eat dirt or play in areas soiled by animals. Covering children’s sandboxes when not in use can also help prevent infection. Pets are a great pleasure for people and the risk of transmitting parasites to humans can be very small if the recommendations are followed.
