The effect of Toxoplasma gondii on the intermediate host
Vosátka, Martin ; Chaloupková, Helena (advisor) ; Hradec, Michal (referee)
Toxoplasma gondii is a protozoan parasite, which has a wide spectrum of warm-blooded hosts, human included. It has worldwide occurrence. The most important role for it has a feline, which serves like a definitive host and allows it to proliferate. The aim of this bachelor thesis was to sum up all identified information so far about the possibilities of relationship between protozoan parasite and its intermediate hosts mainly in area of behavior. Laboratory mouse, the most examined animal associated with behavioral changes, was chosen as an intermediate host. This thesis was also aimed on affecting of human behavior by Toxoplasma gondii in general and about problems connected with it, for example connection with mental diseases and higher risk of traffic accidents. Manipulation of mice by Toxoplasma leads to change in basic instincts necessary for survival. It is especially about attraction to feline odour, when the degree of attraction depends on the dose of stimulus. Area of learning and memory was examined at mice model as well. Worsen ability of learning and memory was demonstrated in most cases (Flegr et al., 2014). Also relationship between number of cysts in the brain and worse results were observed (Vyas et al., 2007). Another important area was human reaction time. Infected individuals had slower reactions, which indicates worsen long-term concentration (Havlíček et al., 2001). Worsen concentration plays an important role and it is connected with a chance of susceptibility to accidents and riskiness for drivers. The individuals with latent Toxoplasma had 2,65 times higher chance for traffic accident (Flegr et al., 2002). T. gondii plays an important role in mental diseases, especially in link with schizophrenia. Effective medication of schizophrenia can inhibit T. gondii (Yolken et al., 2009). Schizophrenia often results in suicide attempt. That is why possible link between suicide attempts and presence of the parasite was researched. The study shows connection between antibody levels of T. gondii and suicide attempts, but just in a subgroup of patients younger than 38 years. It is probably because of risk of suicide attempts in schizophrenia appears in earlier phase of the disease (Okusaga et al., 2011).
