There Giardiasis in cats Is caused by a protozoan known as Giardia duodenalis, Giardia intestinalis or Giardia lamblia. It is not a species-specific agent, but has several genotypes.

Giardia comes in two forms, static oocysts and motile trophozoites.

Life cycle of Giardia duodenalis

There The route of transmission It is contagious when cats are licked or eaten by oocysts that contaminate the environment, food, water or litter. Taking some oocysts within a few days is enough to develop the disease. As a life cycle, Giardia that straight, It has no intermediate host.

It all starts when the cat ingests oocysts, They are gastro-resistant, so they bypass the acidic juices of the stomach to reach the intestines. Reaching the small intestine, it comes out of the oocysts Trophozoite Which multiplies, as well as damages the intestinal wall, creating new oocyst which is later excreted in the environment including feces.

The Holiday period, Ie the interval between receiving oocysts and releasing new ones is 4-16 days. Oocysts do not pass through all stools, which can complicate the diagnosis. Furthermore, these cysts are already contagious: they are released into the environment and it is enough for another cat to start a cycle again by licking contaminated soil or water, food containing oocysts, or just a liter of infected cat.

There The duration of the disease It is changeable. The Holiday period This can last for weeks or months with occasional expulsion of oocysts. On the other hand, the symptoms will persist until the cause is identified and therapy is set.

E.g. Oocysts are then very resistant to the external environment, Under conditions of adequate humidity and temperature they can survive for several months. However, they are sensitive to extreme heat and temperatures below -4 degrees, although they should remain at this temperature for at least a week to become inactive.

The risk of oocysts only if they use this system False negative Too long. If the specimen is very fresh and very parasitic, trophozoites can also be seen: they have a classic “falling leaf” movement, distinct from the rolling movement of the trichomonas fetus.
  • Stool tests for enrichment: To increase the chances of spotting Giardia, choose one Tests made by flotation. In this case, however, it is necessary to repeatedly test on the samples taken for 2-3 days: this increases the chances of diagnosis because not all occlusal oocytes are eliminated.
  • Antibody testThere are tests that can detect the presence of antibodies against Giardia. These tests are OK as a first diagnosis, but not for control because, being antibodies, they remain positive for several months after recovery.
  • PCR: Non-routine outpatient examination, but PCR allows Giardia to be highlighted despite the presence of some oocyst. And it allows you to genotype Giardia, but it costs a lot more than other tests
