Giardia lamblia is a parasitic protozoan that causes giardiasis (a parasitosis). Giardiasis is a disease that affects the digestive system. The main symptom is diarrhea (abundant, liquid, foul-smelling and with substances not absorbed by the body). The cat infected with the Guard has a predisposition to dehydration and weight loss. The cat has no fever but is not very active, tired, lethargic and exhausted. The puppies, being more delicate, are more affected by the Giardia infestation.

Once the microorganism has infected its victim, it lives in the intestine and is transmitted in the feces. Outside the body, Giardia can survive for weeks or even months. A parasite that can live and survive anywhere. It normally lives in stagnant waters, in ponds, in water holes and in non-potable and sewage-polluted waters.

The disease is transmitted via the fecal-oral route. You can become infected by ingesting contaminated water, food or soil, or through the faeces of an infected animal.
