Calculated that the small spiders are able to trigger such reactions at comparatively gigantic man, has evolutionary causes. Even young monkeys are afraid of spiders and beetles. The reservation against the creatures seem to be genetically predisposed. He is to hold them in primates, insects indiscriminately cram into his mouth, because that might indeed be toxic. "Ugh spider!" So an ancient way alert program that can be eased slightly in the normal case of habituation. Despite suffering about 10 percent of arachnophobia INFECTED people worldwide, those people that get triggered in the amygdala stressful situations get out of control and there is panic attacks.

The cysts remain even after a successful treatment in the body, but that is not enough. The agents remain in the cysts, this is where the concern lies.
A transmission from person to person may be made in case of an infection during pregnancy. Toxoplasmosis can then lead to serious complications or malformations in the fetus.
Infection with Toxoplasma
The causative agent of toxoplasmosis is found not only in the faeces of cats, including raw meat may be the source of infection. For this reason, one should not consume uncooked meat in large quantities, and especially during pregnancy . In addition to toxoplasmosis, it can also lead to other diseases such as Salmonella or other transmitted bacteria. The mere touch of carriers of the pathogens is not sufficient for infection. You have to penetrate through the mucous membranes or wounds in the body to cause damage.
A precaution, especially if one has a lot to do with cats, is especially washing hands after emptying the litter box. Thus, as with many other pathogens e.g. (Flu) are also ruled out that they are unintentionally added. For more information on toxoplasmosis exists in this fact sheet on the NHS site.
