A variety of Acanthamoeba spp. pathogenic strains were isolated from water pools in the area of Poznań. In many cases amoebae invaded lungs, kidney heart, liver and diaphragm causing significant changes in these Organs. The presence of amoeba outside of CNS was found mainly in the early periods of infection. Amoeba isolated from different organs of dead animals did not exhibit any specificity in relation to the organs in following infections. Infection with both low-and high-virulent strains resulted in pathomorphological changes of similar character. However, changes induced by low-virulent parasites developed later and were less extensive.

Introduction: The establishment of a high-throughput quantification approach for waterborne pathogenic protozoa and helminths is crucial for rapid screening and health risk assessment.
Methods: We developed a high-throughput quantitative polymerase chain reaction (HT-qPCR) assay targeting 19 waterborne protozoa and 3 waterborne helminths and validated its sensitivity, specificity, and repeatability. The assay was then applied to test various environmental media samples.

Acanthamoeba spp. are widespread protists that feed on bacteria via phagocytosis. This predation pressure has led many bacteria to evolve strategies to resist and survive inside these protists.

Background: Diseases in humans caused by amphizoic amoebae that can result in visual impairment and even blindness, have recently been identified more frequently worldwide. Etiologically complex incidents of keratitis, including those connected with strains detected in Poland, were evaluated in this study.
Methods: Corneal samples from cases resistant to antimicrobial therapy assessed for epidemiological, microbiological and parasitological aspects were investigated by phase-contrast microscope, slit lamp and by confocal microscopy.

The proliferation and chlorine resistance of pathogenic bacteria in drinking water distribution systems (DWDSs) pose a serious threat to human health. In this study, the synergistic effects of ozonation pretreatment and trace phosphate on water quality health risk and microbial stability were investigated in the small-scale DWDSs simulated by biofilms annular reactors with cast iron coupons. The results indicated that ozonation of drinking water containing trace phosphate was equivalent to increasing microbial carbon and phosphorus sources, further leading to the rapid proliferation of opportunistic pathogens (OPs) in subsequent DWDSs.

The fact that free-living amoebae of the genus Acanthamoeba can live in many different environments causes these protozoa to have different interactions with other microorganisms. Investigation of Acanthamoeba-pathogenic bacteria interaction is important for the discovery of new antibacterial agents that can be used against pathogenic bacteria. In this study, it was aimed to investigate the antibacterial effect of cell-free supernatants obtained from Acanthamoeba against some pathogenic bacteria.
