The treatment of acanthamoebiasis is a still a problem. Our previous studies showed that the application of extracts from Artemisia annua L. significantly prolonged the survival of mice infected by Acanthamoeba.

Hygiene pests as vectors for parasitic and bacterial diseases in humans.

Diseases transmitted by hygiene pests remain a very serious problem in spite of fast developments in science and medicine. The present study focuses on pests carrying germs that pose a threat to human health and life. The quick pace of life, the need to satisfy human needs and mass production of food sometimes result in flagrant sanitary, hygienic and epidemiological deficiencies.

Evaluation of the effectiveness of tea tree oil in treatment of Acanthamoeba infection.

Eye diseases caused by amoebae from the genus Acanthamoeba are usually chronic and severe, and their treatment is prolonged and not very effective. The difficulties associated with therapy have led to attempts at finding alternative treatment methods. Particularly popular is searching for cures among drugs made of plants.

Toll-like receptors in the brain of mice following infection with Acanthamoeba spp.

The Toll-like receptors (TLRs) of the innate immune system play an important role in the recognition of pathogens such as bacteria, viruses, fungi, and parasites. In this study, we examined the changes in the level of expression of TLR2 and TLR4 mRNA and protein in the brains of mice infected with Acanthamoeba spp. The Acanthamoeba strains were isolated from a patient with Acanthamoeba keratitis (AK) (Ac55) and Malta Lake (Ac43).

Acanthamoeba infection in lungs of mice expressed by toll-like receptors (TLR2 and TLR4).

Toll-like receptors (TLRs) play a key role in the innate immune responses to a variety of pathogens including parasites. TLRs are among the most highly conserved in the evolution of the receptor family, localized mainly on cells of the immune system and on other cells such as lung cells. The aim of this study was to determine for the first time the expression of TLR2 and TLR4 in the lung of Acanthamoeba spp.

Artemisia annua L. as a plant with potential use in the treatment of acanthamoebiasis.

The treatment of acanthamoebiasis is a great problem. Most cerebral invasions end with death, and the treatment of ocular invasions is usually long-lasting and not very effective. Numerous plant extracts and substances isolated from plants, which are effective against trophozoites or cysts, have been studied in the treatment of acanthamoebiasis.

Parasitic diseases in humans transmitted by vectors.

Despite the considerable progress of medicine, parasitic diseases still pose a great threat to human health and life. Among parasitic diseases, those transmitted by vectors, mainly arthropods, play a particular role. These diseases occur most frequently in the poorest countries and affect a vast part of the human population.

Genotypic characterization of amoeba isolated from Acanthamoeba keratitis in Poland.

Free-living amoebae belonging to the genus Acanthamoeba are the causative factor of many diseases. Among others, they cause Acanthamoeba keratitis (AK), a condition that usually occurs in contact lens wearers, though it is also observed in non-wearers. The number of diagnosed cases of AK increased more than eightfold during 8 years in the USA, and a proportional increase in frequency also occurred in Poland and Europe.
