[Amoeba of the Acanthamoeba species in swimming pools and lakes of the Lublin area and in people using contact lenses].

Examinations of water for the presence of Acanthamoeba in covered and open air swimming pools and lakes of the city of Lublin were performed in order to determine the places where the invasion of amoebas of Acanthamoeba kind on the eyes can occur. Pathogenic strains of Acanthamoeba were found in all collected water samples. The cultures from the conjunctival sac of regular swimmers practising every day in these pools were taken. Amoebas were found in none of the examined cultures. The observations have shown that contact lenses should be protected from the contamination with swimming pool water. Amoebas were not revealed in the conjunctival sac of the swimmers after bathing.

[Histologic changes in lungs of mice experimentally infected with amoebae of the "limax" group].

The studies revealed that the infection with the "limax" group amoebae resulted in the severe changes in the respiratory system: in interstitial pneumonia, the injuries of the bronchi, the bronchioles and the blood vessels. The histopathological examinations showed the focal destruction of the alveoli in case of the mild amoeba invasion while the massive invasion caused the complete destruction of the respiratory epithelium, the blood vessels, the bronchi and the bronchioles. Apart from all the changes in the alveoli, in most cases the significant pulmonary hyperaemia and the numerous blood foci were observed. Moreover, the histopathological changes in the blood vessels, the bronchi and the bronchioles consisting in the epithelial destruction and the laceration of the blood vessel walls and the bronchioles were disclosed.

[Amebic keratitis-keratitis acanthamoeba].

In seventeen patients who suffered of corneal ulcer, and were negative in bacteriological and mycological examinations, parasitological tests were performed between 1990-1992. Acanthamoeba keratitis was diagnosed in one patient with characteristic corneal changes of right eye following trauma. The patient was not a contact lens wearer. The amoeba found in direct smears of scraping from corneal ulcer and isolated and cloned in in vitro conditions (isolate-clone-No. 2961) belonged to Acanthamoeba polyphaga species. The trophozoites showed a low degree of invasiveness and high virulence when tested in BALB/c mice. The authors discussed the epidemiology of Acanthamoeba keratitis and pointed out to the necessity of accurate laboratory diagnosis and discerning interpretation of the results to prevent an Acanthamoeba-phobia among the potential patients and most of all among the medical staff.
