Allergic Fungal Rhinosinusitis in Europe: Literature Review and Own Experience.

Allergic fungal rhinosinusitis (AFRS) is primary, Th2-mediated, chronic rhinosinusitis, which is diagnosed when the criteria defined by Bent and Khun are met. The disease is most common in countries located in the subtropical and tropical regions characterized by high temperatures and high levels of humidity, which favour the wider occurrence of fungi in the environment. The presence of specific IgE antibodies directed against fungal allergens, which is one of the diagnostic criteria, proves the systemic nature of the disease and allows one to distinguish AFRS from eosinophilic fungal rhinosinusitis.

A new pathway for naproxen utilisation by Bacillus thuringiensis B1(2015b) and its decomposition in the presence of organic and inorganic contaminants.

Bacillus thuringiensis B1 (2015b) is a bacterial strain that is able to degrade naproxen. However, the potential effect of water co-contaminations on the degradation process and its pathway have not yet been evaluated. The results of our study show that in the presence of aromatic compounds, the B1 (2015b) strain utilised naproxen with an efficiency that was similar to what it was with no aromatic co-contaminations.

Naproxen ecotoxicity and biodegradation by Bacillus thuringiensis B1(2015b) strain.

High level of naproxen consumption leads to the appearance of this drug in the environment but its possible effects on non-target organisms together with its biodegradation are not well studied. The aim of this work was to evaluate naproxen ecotoxicity by using the Microbial Assay for Risk Assessment. Moreover, Bacillus thuringiensis B1(2015b) was tested for both ecotoxicity and the ability of this strain to degrade naproxen in cometabolic conditions.
