The aim of this work was an assessment of a microbiological quality of some dried herbs, offered in retail. A basil (Ocimum basilicum L.), marjoram (Origanum majorana L.), oregano (Origanum vulgare L.) savory (Satureja hortensis L.), tarragon (Artemisia dracunculus L.) and thyme (Thymus vulgaris L.) were investigated. The research material included 28 samples coming from five producers and was purchased in Szczecin in shops of various commercial networks. It was stated that the microbiological contamination was significantly differentiated depending on both: a kind of herbs and a producer. A mean count of microorganisms was the highest in basil while the lowest counts were detected in oregano and savory. A microbiological quality of the majority of the tested herbs attained standards. However, in 25% of the samples an excessive amount of bacteria (>105cfu∙g-1) was detected. Only in individual cases, there was a high contamination by moulds (>103cfu∙g-1) and coliforms (present in 0.01–0.001 g). Nevertheless, there were no E. coli, Salmonella sp. and coagulase (+) staphylococci in any sample.

Infections related to modern surgical procedures present a difficult problem for contemporary medicine. Infections acquired during surgery represent a risk factor related to therapeutical interventions. Eradication of microorganisms from hospital operating theatre environment may contribute to reduction of infections as the laminar flow air-conditioning considerably reduces the number of microorganisms in the hospital environment. The objective of the study was to evaluate the occurrence of fungi in air-conditioned operating theatre rooms. The study was carried out in one of the hospitals in Kraków during December 2009. Indoor air samples and imprints from the walls were collected from five operating theatre rooms. A total of fifty indoor air samples were collected with a MAS-100 device, and twenty five imprints from the walls were collected using a Count Tact method. Fungal growth was observed in 48 air samples; the average numbers of fungi were within the range of 5–100 c.f.u. in one cubic metre of the air. Fungi were detected only in four samples of the wall imprints; the number of fungi was 0.01 c.f.u. per one square centimetre of the surface. The mould genus Aspergillus was most frequently isolated, and the species A. fumigatus and A. versicolor were the dominating ones. To ensure microbiological cleanness of hospital operating theatre, the air-conditioning system should be properly maintained. Domination of the Aspergillus fungi in indoor air as well as increase in the number of moulds in the samples taken in evenings (p<0.05) may suggest that the room decontamination procedures were neglected.

Contamination with bioaerosols most affects the livestock production, and especially the poultry. Prolonged or repeated exposure to high concentrations of airborne fungal spores is considered a major risk factor for human health and contributes to the deterioration of lung functions, and particularly allergic diseases. The aim of the study was to determine the number and quality of moulds and yeasts in the air of various objects for poultry post-slaughter waste processing. The study allowed to detect the presence of moulds and yeasts in the air of all sampling points. There were: Aspergillus sp., Penicillium sp., Scopulariopsis sp., Trichoderma sp., Acremonium sp., Cephalosporium sp., Alternaria sp., Pithomyces sp., Eurotium sp., and: Rhodotorula sp., Candida sp., Yarrovia sp. and Saccharomyces sp. Statistical analysis confirmed the presence of highly significant influence of the sampling point, date, and interaction of these factors on the fungi population.

Aerobiological measurements were made by the volumetric method (VPPS Lanzoni and Burkard instruments). Concentrations of microscopic fungi were measured from April 16th to July 2nd, 2013, in two rooms of the Chair of Botany and Natural Environment Protection, Faculty of Biology, Szczecin University. The study was undertaken to perform mycological analysis of the air in selected rooms. Mycological contamination of the air in the surveyed areas was not diverse in terms of species composition. Nearly three times higher concentrations of fungal spores were recorded in the seminar room. The most abundant were spores of fungi from the genus Cladosporium. The concentration of fungal spores of Cladosporium, Botrytis and Aspergillus/Penicillium exceeds the limits.

Present work contains the attempt to compare methods of microorganisms identification, for example, the similarity between species – molecular and classical. The both methods were used because classical approaches based on the use of morphological criteria are, as in several other fungi, difficult to apply in Trichoderma, due to plasticity of characters to interpret. Consequently, almost all recent studies have used molecular data to characterize and identify species. The comparison of these two techniques is based on using guidelines of macroscopic and microscopic evaluation of few classical factors as well as RAPD and RFLP – molecular techniques. Results indicate that none of the technique being compared is adequate when used alone, although molecular ones are more accurate. There is no complete convergence between RAPD and RFLP what makes it even harder to interpret but this fact can be the result of inconvenient markers used in experiment.

Contamination of feed with zearalenone (ZEA) is still a serious problem in farm animals feeding, especially in gilts, sensitive to this compound. The relative failure of current methods of decontamination and quality control lead us to look for new techniques. The commonly accepted method for breaking down ZEA was performed in controlled temperature and time conditions. Various sodium carbonate doses (0.5 – 4%) were added to feed naturally contaminated with ZEA (ZEA biosynthesis by F. graminearum isolates). These doses were found to be effective in in vitro studies. The addition of 2% sodium carbonate gave the best results in reducing the phytoestrogen in the feed.

The results of the tests of the effectiveness of the action of new, not yet described in the literature group of biocidal ionic liquids were synthesised and presented. Those ionic liquids are derivatives of the leading structure, i.e. didecyldimethylammonium nitrate, and demonstrate strong action against mould fungi. Natural quaternary ammonium salts, mainly extracts from coconut and soybean, and from vegetable fats, were the basis for syntheses. Mycological tests were carried out on the wood of pine Pinus sylvestris L. (sapwood) in accordance with the method assumed binding for the assessment of biocide efficacy.

Damp dwellings represent suitable conditions for extended indoor moulds. A cellulolytic micromycete Stachybotrys chartarum (Ehrenb.) Hughes is considered to be a tertiary colonizer of surfaces in affected buildings. Known adverse health effects of S. chartarum result from its toxins – trichothecenes or atranones, as well as spirolactams. Mechanism of their potential pathological effects on the respiratory tract has not yet been sufficiently clarified. The cytotoxic effects of complex chloroform-extractable endo- (in biomass) and exometabolites (in cultivation medium) of an indoor S. chartarum isolate of an atranone chemotype, grown on a liquid medium with yeast extract and sucrose at 25oC for 14 d, on lung tissue were evaluated in the 3-day experiment. For the purpose, 4 mg of toxicants were intratracheally instilled in 200 g Wistar male rats. A trichothecene mycotoxin diacetoxyscirpenol was used as the positive control. Bronchoalveolar lavage (BAL) parameters - viability and phagocytic activity of alveolar macrophages (AM), activity of lactate dehydrogenase, acid phosphatase and cathepsin D in cell-free BAL fluid (BALF), as well as in BAL cells, were measured. Acute exposure to the metabolites caused statistically significant changes, indicating lung tissue injury in the experimental animals. Decreased AM viability and increased activity of lysosomal enzyme cathepsin D in BAL cells after fungal exometabolite exposure were the most impressive. As toxic principles were found predominantly in the growth medium, toxins were more likely responsible for lung cell damage than e.g. fungal cell wall components. S. chartarum toxic metabolites can contribute to the ill health of occupants of mouldy building after inhalation of contaminated aerosol.

Resistance causes of moulds to N,N-bis(3-aminopropyl)dodecylamine (APDA) for selected species of Aspergillus niger and Aspergillus flavus was examined. Control (sensitive) strains and resistant strains, cultured at 0.05% triamine, were used in the experiments. The non-resistant strains did not have growth capacity in this amount of ADPA while the resistant strains were characterised by a smaller biomass increase. Individual stages of the development of the mycelium occurred later than those in the control samples. The participation of the cell wall in the mycelium biomass of the resistant strains was higher by 7.5%. The glucan content in the wall dry mass was lower by 11% than that in the sensitive strains. A 41% increase in the lipid content was recorded in the cell wall of resistant Aspergillus flavus. A 21 % protein increase occurred in the wall of Aspergillus niger comparing to the control strain. Infrared spectrophotometry analysis of the cell wall did not reveal the presence of triamine. Most absorption bands disappeared in the wall of Aspergillus flavus while no additional absorption bands were registered in Aspergillus niger, some bands were only stronger than those in the control sample. The resistant strains were characterised by a smaller ergosterol content, the main constituent of cell membranes. Spectrophotometry analysis of the mycelium did not reveal significant qualitative changes; only quantitative changes were observed. It was noticed that the resistance reaction did not occur with the same intensity in both species studied. The resistant strain of Aspergillus niger was characterised by a slightly more intensive absorption within its entire spectrum range in comparison to control strain. In case of Aspergillus flavus the absorption was higher for control strain.
