What effect does toxoplasmosis have on humans?
Untreated, these infections can lead to blindness

Does toxoplasmosis affect the human brain?
Your brain on Toxoplasma
Infection with Toxoplasma
does not usually produce symptoms in humans unless their immune systems are compromised
, but the parasites remain in the body for life as latent tissue cysts. These tissue cysts are commonly found in the brain, heart and skeletal muscle.
What are the long term effects of toxoplasmosis?
The long-term or chronic effects of the infection result when the cysts spread to the brain and muscle cells. The cysts, which can stay in the body as long as the person lives, can
rupture and cause severe illness including damage to the brain, eyes and other organs
.
How likely are you to get toxoplasmosis from cats?

All mammals including humans are considered intermediate hosts and can become infected, but cannot shed the eggs of the parasite and infect others. It is considered that greater than 40% of humans and
30% of cats have been exposed to Toxoplasmosis
and would have a positive antibody test.
Can parasites change your personality?
In the new study, a pattern appeared in infected men: the longer they had been infected, the less conscientious they were. This correlation supports the researchers' hypothe-sis that
the personality changes are a result of the parasite
, rather than personality influencing the risk of infection.
Should I be worried about toxoplasmosis?
Of those who are infected however, very few have symptoms because a healthy person's immune system usually keeps the parasite from causing illness. However,
pregnant women and individuals who have compromised immune systems should be cautious
; for them, a Toxoplasma infection could cause serious health problems.
How do you know if cat has toxoplasmosis?

. Cysts remain in the body for life. The effects of congenital toxoplasmosis are also life-long.
How does toxoplasmosis leave the body?
Most studies of egress have taken advantage of the fact that T. gondii can be rapidly induced to exit its host cells through
permeabilization of the host cell with detergents or bacterial toxins
(2, 30) or by exposing cells and parasites to calcium ionophores (13) or dithiothreitol (40).
Does toxoplasmosis change human behavior?
gondii has been linked to behavioural changes in humans
. Toxoplasma infection is classically associated with the frequency of schizophrenia, suicide attempts or “road rage”. A more recent study shows that toxoplasma infection prevalence was a consistent, positive predictor of entrepreneurial activity.
How do you test for toxoplasmosis?
A test that measures immunoglobulin G (IgG)
is used to determine if a person has been infected. If it is necessary to try to estimate the time of infection, which is of particular importance for pregnant women, a test which measures immunoglobulin M (IgM) is also used along with other tests such as an avidity test.
Does toxoplasmosis cause you to love cats?
Bizarrely, new research raises that question, finding that
the parasite Toxoplasma gondii, which lives in cats, actually makes cats attractive — rather than scary — to their natural prey
(in this case, rats).

a significant association with bipolar disorder (BD) and suicidal/aggressive behaviors has also been detected
.
Can toxoplasmosis cause psychosis?
As research has shown,
Toxoplasmosis could be related to developing a psychotic disorder
or alternatively Toxoplasmosis could cause psychotic symptoms by affecting similar brain regions and clinical manifestations might mimic a disorder like schizophrenia [4]. Schizophrenia may well be a syndrome with many forms.

Can cleaning a cat litter box make you sick?
Overexposure to ammonia
Inhaling cat urine can also make you sick
. A cat's urine is full of ammonia, a toxic gas that can cause headaches, asthma attacks and even serious respiratory diseases such as pneumonia. Children, older adults and people with weak immune systems are at increased risk.
Can you get toxoplasmosis from smelling cat poop?
gondii infectious organisms are excreted only in cat feces, wild and domestic cats are the parasite's ultimate host. Although you can't “catch” toxoplasmosis from an infected child or adult,
you can become infected if you: Come into contact with cat feces that contain the parasite

gondii with a long exposure time of at least 3 hours. Tachyzoites and tissue cysts are susceptible to most disinfectants, including
l% sodium hypochlorite and 70% ethanol

Can toxoplasmosis live on surfaces?
The parasite becomes infective one to five days after it is passed in the feces of the cat.
