Fungi are the agent of serious contagious diseases that are often zoonosis. Fungal infections can by divided into dermatophytoses, subcutaneous infections and systematic infections. Dermatophytes are one of the most frequent skin diseases of pets throughout the world. The disease is spread among animals and humans. There is often no species barrier. For people the greatest role in infection play Microsporum canis, Trichophyton mentagrophytes and Trichophyton verrucosum. Dogs and cats, the two most popular pets, are believe to be the main source of dermatophytes infections in human. But nowadays also small mammals should be taken into consideration. Dermatophytoses are common in rodents especially in guinea-pigs and chinchillas as well as in rabbits. These animals are often bought to children, who are susceptible to mycotic infections. © 2010 Cornetis.

Background: Dermatophytosis are one of the most important zoonosis. Cats are commonly believed to be the main source of those zoophilic dermatophytes. Aim: The aim of this research was to verify if small mammals, e.g. rodents or leporids can also play an important role in the spreading of dermatophytosis. Material and methods: The authors have examined 43 animals from 5 different species (guinea pig, hamster, rat, rabbit, degu). Skin and hairs specimens were collected and tested with standard mycological procedures, e.g. direct microscopic examination, fungi culture. Antimycogramms were done as well. Results: Clinical dermatophytosis and asymptomatic carriers were found. Dermatophytes were isolated from 15 (34.9%) of 43 examinated animals, 4 of them were free of clinical lesions. Conclusion: Small mammals can be a source of dermathophytes and play an important role in the spreading of the disease. © 2010 Cornetis.

Mycotoxins are secondary metabolites produced by a variety of moulds on several agricultural commodities under specific environmental conditions. The main mycotoxigenic fungi are the Aspergillus spp., Penicillium spp. and Fusarium spp. genera. The main mycotoxins of interest for human health being aflatoxins (AF), ochratoxins (predominantly ochratoxin A; OA), trichothecenes (inc. deoxynivalenol - DON), fumonisins (FB) and zearalenone (ZEN). Among food contaminants, these mycotoxins will have greater consequences in terms of both human and animal health. They can cause cancer (AF, OA, FB), nephrotoxicosis (OA, FB); neurotoxicosis (FB); lung disease (FB); hepatotoxicosis (FB). Research has also demonstrated subtile effects of mycotoxin contamination, including reduced immune function with compromised resistance to infection and disease (DON, AF, OA). When animals ingest the contaminated feeds, some toxins can be metabolized and remain in milk, meat and eggs, which are used for human foods production. The levels of the most dangerous for humans toxins, such as aflatoxin (AF M1 and AF B1) and ochratoxins (OA) present in these secondary sources are much lower than those in agricultural commodities, but mycotoxin control measures have been implemented and legislation concerning mycotoxins have been introduced. It is also important to find methods of decreasing mycotoxin levels in human foods of animal origin. © 2010 Cornetis.

Easy-to-clean and easy-to-disinfect surfaces play a key role in keeping the right sanitary and hygienic standards in hospitals, veterinary clinics and food processing plants. In recent years, due to the development of nanotechnology, self-cleaning and self-disinfecting surfaces are applied on an increasing scalê. They are covered by photocataiytic surfaces made of nanomaterials (NMs) on which, upon exposure to the ultraviolet radiation, advanced oxidation processes (AOPs) can take place. Those processes present an effective method of bacteria eradication. One of the most studied AOPs in relation to microorganism eradication is the TiO2/UV-process, where titanium dioxide (TiO2) is used as a photocatalyst, and the ultraviolet radiation (UV) is used as an agent generating free radicals. The high efficiency of the gram-negative and gram-positive bacteria inactivation by the methods using photocataiytic properties of nano-sized TiO2 (nano-TiO2) contributes towards its increasing application. Disinfection based on free radicals reactions is considered to become one of the most promising tools to solve difficult problems related to hygiene and public health protection in the near future.

Studies on the effects of environmental factors and technological processes on the behavior of microorganisms in food have been conducted for many years. Mathematical models have come to be used extensively for quantitative interpretation of the results of these studies. The use of modeling in food microbiology has grown to the point of being recognized as a distinct discipline of food microbiology, termed predictive microbiology. In recent years, progress in this field has been impressive, and predictive microbiology is increasingly used by food producers and food inspectors in their routine work. One of the reasons for this development are changes in European food law, particularly the obligatory introduction of HACCP, risk analysis and microbiological criteria for food. Predictive microbiology has been an important supporting tool in food chain risk management.
