So it's not a complete surprise scientists have discovered the same behavioral changes associated with toxoplasmosis in rats and mice — reduced anxiety, fearlessness and an attraction to cat urine — are also expressed in humans infected
with the oocysts, according to Peter Marra and Chris Santella, authors of «Cat Wars: The Devastating Consequences of a Cuddly Killer.»
The paper observes that «It is important to both inform susceptible individuals and the general populations that meat should be cooked thoroughly, fruits and vegetables should be washed before consumption, and contact
with oocysts should be avoided, particularly when changing cat litter.
Not exact matches
Humans can become infected after unintentionally ingesting the microscopic
oocysts, primarily from not their washing hands after cleaning a cat's litter box or working in a garden
with contaminated soil.
Since incredible numbers of
oocysts are shed from infected pets, the environmental contamination
with coccidia
oocysts is severe.
In other cases, a puppy or kitten becomes infected
with coccidiosis, produces lots of
oocysts of coccidia but never has clinical signs of disease such as diarrhea, loss of appetite, vomiting or failure to thrive.
Since cats who have been infected shed
oocysts only once (repeated shedding has only been seen in a laboratory setting in cats
with severely compromised immune systems), sterilized cats in managed colonies that have the parasite are no longer producing the
oocysts.
The
oocyst shedding leads to the other mode of infection for people and other warm - blooded animals: consuming feces that contain the
oocysts, such as by eating a plant
with feces residue or by gardening and not washing your hands before eating.
Pregnant moms and immunocompromised people
with cats who can not get someone else clean the litter box for them should wear gloves, clean the litter box promptly twice a day before the

Nonetheless, the data reveal that ownership of a cat is not necessary to acquire T. gondii, because it has been shown that
oocyst exposure is not always associated
with cat ownership or
with recognition of risk factors.
Indeed, as cats increasingly contaminate public areas
with T. gondii
oocysts it will become progressively more difficult to avoid exposure.»
Because of their fastidious nature, the passing of non-infective
oocysts, and the short duration of
oocyst shedding, direct contact
with cats is not thought to be a primary risk for human infection.»
[14, 15] It's generally thought that
oocysts (the mature, infective form of the parasite) are transferred from soil contaminated
with infected feces to coastal waterways by way of freshwater run - off.
