One of them Intestinal parasites Where we can come across our four-legged friends Dog giardia.

Dog giardia: the cause and what it is
Giardia a Protozoan Very common worldwide, known as being able to develop an intestinal parasitosis giardiasis. It is important to point out You cannot see Giardia with the naked eye Inside Dog feces. You can see roundworms and tapeworms, but you can’t see giardia or coccidia. 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.
Symptoms of Giardia in dogs
The symptoms of Giardia are quite variable. Sometimes an occasional finding in this case Asymptomatic dogOther times, you have dogs with impeccable stools, but that is the only visible signs of weight loss. Giardia can be an acute, intermittent form of the disease. The dog will alternate periods with normal stools with periods of soft or prolonged stools.
