Most mycoses are caused by fungi that reside in nature. The severity of the infection depends on the pathogenic attributes, socioeconomic factors and local environmental conditions. Recent diagnosis increasingly relies on not only the clinical features. Molecular identifications have determined the need for a rapid and easy method of extracting DNA. Usually two factors have to be considered: maximize the DNA yield and ensure that the extracted DNA is susceptible to enzymatic reactions. These data suggest that phenol-chloroform methods and a 7-day culture period may be useful for validation and constitute the first step of molecular diagnosis of dermatophytes.

A particularly important factor in the epidemiology of bacterial infections is the introduction of pathogens posing a risk to other animals and humans into the soil, plants and especially water, as contaminants together with faeces. Our study presents screening of potentially pathogenic bacteria in different populations of deer that were displaced under reintroduction programmes. Based on our own research and the literature data, it seems that wild ruminants play an important role in the maintenance of zoonotic pathogens and information about zoonoses from red deer will become increasingly important as deer populations continue to grow, especially in Europe.

Ten common phenolic compounds from five plant extracts i.e. Hypericum perforatum L., Matricaria recutita L., Achillea millefolium L., Thymus vulgaris L. and Salvia officinalis L. were separated using optimized TLC conditions and visualized using NP/PEG reagent.Antioxidant properties of components of the extracts were assessed using TLC-DPPH • directly on the TLC plate. Nine from ten analyzed polyphenols were proved to be radicalscavengers. The presence and identity of target substances in plant samples were confirmed by LC-MS technique.

Canine parvovirus disease appeared in the world and in Europe during the second half of the 1970s. Over the course of 40 years the original CPV-2 strains mutated and variants 2a, 2b and 2c appeared. Their appearance is connected with specific amino acid changes, mainly in the capsid protein VP2. Strains isolated by the authors were adapted for in vitro cell culture. Phylogenetic analysis revealed differences between strains isolated in Poland in 1982-1985 and in 1995-2009. Strains from the 1980s were shown to belong to variant CPV-2a (11 strains) and variant 2b (2 strains), while no fundamental differences were found among the genetic profiles of the strains from 1995-2009, which were classified as belonging to variant 2c.
