Which can only be seen under a microscope.

This is vital to repeat because many owners see compact stools without any apparent signs of worms or parasites and make sure their dog is healthy. But that is not always the case.

Life cycle of Giardia duodenalis

The Life cycle of Giardia duodenalis He is direct, he has no intermediate guests.

Giardia has two forms, oocysts and trophozoite. The infectious form is the oocyst which is eliminated through dog feces, thus contaminating the whole environment. The oocysts are quite resistant.

Under favorable conditions of temperature and humidity (they especially prefer moist soil) they can remain effective and contagious for several months (which explains why dogs regenerate). Trophogite on the other hand is form flagellate Mobile that is in the dog’s nickname (as opposed to where cats live fast).

There Infection of Giardia It runs through Through the fecal-oral route. The dog only needs to lick food, water or soil that is contaminated by the oocyst that has been excreted in the feces by other animals, including humans, to become infected. Cyst gastro-resistant, acid excretes and reaches gastric juice intactSmall intestineWhere it resides.

Here the oocyst turns into a flagellated trophozoite. Trophozoites attach themselves to the intestinal mucosa by replicating. It is at this stage that Damages epithelial cells Symptoms of intestinal cause.

Some trophozoites are excreted in the feces, but they die quickly, which means that if we find them in the feces, the specimen is extremely fresh. Others, however, become oocyst as they pass through the intestines, which are excreted in the feces, ready to begin the cycle again.

The Incubation time This is very fast, we talk for a few days and the reason is that the accepted oocysts are immediately contagious.
