New prevention strategies in HIV infection
Buriánková, Lucie ; Španielová, Hana (advisor) ; Drda Morávková, Alena (referee)
This bachelor theses deals with the new preventive methods in the fight against HIV (Human Immunodeficiency Virus). Chapter 1 is aimed at the HIV characterization. The next chapters dwell on the preventive methods, whether these are ABC methods (abstinence from sex, being faithful, use of condoms), which belonging to the old preventive strategy in HIV struggle or innovation methods like male circumcision, vaginal diaphragm, microbicides and HIV vaccines. The final chapter deals with the situation in Czech Republic and various ways of educational training at czech schools.

Sexual transmission of Toxoplasma gondii from males to females: experimental verification using laboratory animal model
Navrátil, Jiří ; Kodym, Petr (advisor) ; Votýpka, Jan (referee)
Toxoplasma gondii is cosmopolitly living parasite which prevalence in human extends to tens of percent. In its life cycle it uses any homoiothermic vertebrate as an intermediate host. The definitive host are felines from Felidae family. The acute phase of infection is medically important in immunocompromised pacients and by its risk of congenital toxoplasmosis in pregnant women who never suffered from this illness before. Infection could have serious and rarely even lethal consequences in both cases. This thesis focuses on experimental verification of theory of sexual transmission of toxoplasmosis from male to female on laboratory mice. Possible transmission was tested in acute phase and latent phase of infection. The result was negative in both cases. Moreover, we observed the parasite's affinity to tissue of organs in male mice by PCR technique. Particularly, our interest was in comparing genital organs with others. It was discovered that lungs and spleen are the most infected organs in acute phase of infection. Toxoplasma was also present in genital organs (especially in epididymis) but not more frequently than in others. We observed statistically significant difference between sexual and non-sexual organs in acute and latent toxoplasmosis - non-sexual organs were more infected in both phases....

Influence of latent toxoplasmosis on human fertility
Hlaváčová, Jana ; Kaňková, Šárka (advisor) ; Calda, Pavel (referee)
Toxoplasma gondii is one of the most widespread parasitic protozoa in humans in developed countries. It has a wide range of hosts including various warm-blooded animals and humans. Recent studies suggest that it could influence the fertility of humans. The aim of this work was to find out, what is the prevalence of toxoplasmosis in groups of women and men with fertility problems and whether Toxoplasma gondii has an effect on specific fertility parameters. In women, Significant positive correlation between toxoplasmosis and the percentage of oocytes in the follicles was found among women. Group of men with semen pathology diagnosis revealed a statistically significant negative association between toxoplasmosis and the percentage of morphologically normal sperm. It seems that latent toxoplasmosis in men can also worsen the negative effect of tobacco smoking on fertility. The impairment of fertility in men could be the result of the manipulation activity of Toxoplasma gondii, which leads to more frequent sexual intercourse due to decreased ability to conceive. This could increase the likelihood of sexual transmission, which is currently suggested as one of the possible ways of transmission of toxoplasmosis.
