Parasites and fungi as risk factors for human and animal health

Abstract

Recent literature data suggests that parasitic and fungal diseases, which pose a threat to both human and animal health, remain a clinical, diagnostic and therapeutic problem. Attention is increasingly paid to the role played by natural microbiota in maintaining homeostasis in humans. A particular emphasis is placed on the possibility of manipulating the human microbiota (permanent, transient, pathogenic) and macrobiota (e.g., Trichuris suis) to support the treatment of selected diseases such as Crohn's disease, obesity, diabetes and cancer. Emphasis is placed on important medical species whose infections not only impair health but can also be life threatening, such as Plasmodium falciparum, Echinococcus multilocularis and Baylisascaris procyonis, which expand into areas which have so far been uninhabited. This article also presents the epidemiology, diagnosis and treatment of opportunistic parasitoses imported from the tropics, which spread across large groups of people through human-to-human transmission (Enterobius vermicularis, Sarcoptes scabiei). It also discusses the problem of environmentally-conditioned parasitoses, particularly their etiological factors associated with food contaminated with invasive forms (Trichinella sp., Toxoplasma gondii). The analysis also concerns the presence of developmental forms of geohelminths (Toxocara sp.) and ectoparasites (ticks), which are vectors of serious human diseases (Lyme borreliosis, anaplasmosis, babesiosis), in the environment. Mycological topics contains rare cases of mycoses environmentally conditioned (CNS aspergillosis) and transmissions of these pathogens in a population of hospitalized individuals, as well as seeking new methods used to treat mycoses.
