Synopsis
CAPC Recommends Cats who test positive for antibodies to Toxoplasma gondii should be considered unlikely to shed infectious oocysts; most infected cats will also remain asymptomatic. Remove cat feces on a daily basis from the litter box; T. gondii oocysts must develop for 1-5 days after being passed in the feces to become infectious.
Species
Toxoplasma gondii is the causative agent of toxoplasmosis, one of the most important zoonotic parasites.
Disease
Toxoplasmosis is a multisystemic infection characterized by granulomatous inflammation associated with tachyzoite proliferation in the tissues. In small animal practice, the disease is most commonly seen in immunocompromised cats and, occasionally, dogs.
Prevalence
Toxoplasmosis is a common, worldwide infection affecting a large variety of mammals and birds. Prevalence of oocysts (fecal stage) in cats in the United States is quite low.
Diagnosis
Non-sporulated oocysts (10 µm by 12 µm) are shed in feline feces. The oocysts of T. gondii are morphologically indistinguishable from those of Hammondia sp. and Besnoitia sp. which may also be present in feline feces.
Treatment
There is no approved treatment for toxoplasmosis in cats or dogs. However, the following medications and regimens have been used successfully.
Public Health Considerations
Follow the recommendations for prevention of infection in cats to limit human transmission from oocysts. Direct contact with cats is not considered to be a risk factor for T. gondii infection in people, particularly when cats are kept indoors and fed a commercial diet.
