Enterococci are found in the gastrointestinal tract of humans and animals, in soil, and in water, but they also have a long history of use in the production of traditional fermented food. Some strains of enterococci are considered as emerging pathogens of humans. The intrinsic and acquired resistance of enterococci to antibiotics has special significance. Food of animal origin may be a source of resistant enterococci. The main cause of food contamination with enterococci is improper cleaning and disinfection of equipment. The aim of this study was to assess the antibiotic susceptibility of enterococci isolated from different types of food of animal origin and the ability of these microorganisms to form biofilm. Out of a total of 63 isolates, relatively few enterococci were resistant to gentamicin (1.59%). The highest level of resistance was noted for vancomycin (7.94%) and ampicillin (9.52%). However as many as 19.05% and 44.44% of enterococci were resistant to erythromycin and tetracycline, respectively. The ability to form biofilm was detected in 14.29% of the strains of enterococci tested.

Feed-efficient ruminant production is a key topic in the further development of ruminant husbandry all over the world. Ruminants contribute substantially to human nutrition by production of milk and meat. They are also extremely useful for mankind by providing other important products and labour, such as skins, clothing, bones, dung, heating material, and working as draft animals, etc. The microorganisms in the rumen of ruminants are able to process lignocellulose from low quality roughage into volatile fatty acids and energy, to transfer non-protein nitrogen, such as urea, into microbial protein, and to synthesize B vitamins. Therefore, ruminants are able to produce food of animal origin without competition for feed with non-ruminants and man. On the other hand, gas methane (CH4 ) with a high greenhouse gas potential is an unavoidable by-product of rumen fermentation. Furthermore, growing ruminants are characterized by a low growing potential (daily yield in edible protein < 0.05% of body weight). The objectives of ruminant breeding, nutrition and keeping/management should, therefore, be to maximize/optimize the advantages of ruminants and to minimize their disadvantages. Feed-efficient ruminant production is viewed as a complex system starting with plant and animal breeding. More systemic approaches are considered necessary to understand interactions and to find acceptable solutions for complex relationships in the context of food security, resource efficiency, as well environmental, social and economic aspects.

Comparative study of microfossils from two kinds of sediments: chert intercalations (studied in thin section) and phosphorite/phosphatic carbonate (in thin section and maceration), from the upper Neoproterozoic Doushantuo phosphorites in the Weng’an area, Guizhou Province, South China, shows that the phosphatized Megasphaera ornata and the chert−preserved Tianzhushania tuberifera should be regarded as representing the same taxon preserved by different mineralization processes. In phosphatized specimens the outer wall is often peeled off, exposing the ornamented middle wall. Some phosphatized specimens isolated from the rock matrix and specimens seen in thin sections of phosphorites show a partly preserved outer wall with spines, which can be compared to the thin−sectioned specimens from the chert beds. The small pits usually seen on the surface of the ornamented middle wall of phosphatized specimens correspond to the attachment spots of the spines in the outer wall. The presence of a spiny outer wall is a characteristic of Tianzhushania Yin and Li, 1978. Tianzhushania ornata (Xiao and Knoll, 2000) comb. nov. is here proposed as the valid name for the species. The proposed resting−egg nature of T. ornata, mainly based on the ornament type of the middle wall, cannot be excluded. The presence of a spiny outer wall, however, suggests that it is a pelagic rather than a benthic form.

Biogenic amines can be naturally present in many foods and they can also be produced in high amounts by the activity of amino acid decarboxylases of microorganisms. If ingested in significant amounts they may produce direct or indirect effects on a consumer’s health. In food microbiology, their large presence has been associated to spoilage and fermentation processes. The aim of the present study was to assess the content of biogenic amines (single and total value) in Tuscan traditional cheeses and sausages. Thirty samples of these products were tested. Biogenic amines content was analyzed by a HPLC-UV method. Tyramine was, in all the matrices, the amine most often detected and quantified, followed by putrescine and cadaverine. In conclusion, except in dry sausages, the data obtained in the present study suggest these traditional foods have generally low biogenic amines total content.

As a result of the research carried out in 1983-1993 (with consideration for the results of the research conducted before WWII by German entomologists) in the Bielinek forest-steppe reserve 57 species of click beetles were found (Elateridae, Eucnemidae, Throscidae). The zoogeographical and ecological characteristics of click beetles fauna of the area was presented. As a result a high share of species related to Submeridian-Atlantic climate was found in the reserve as well as the species which in terms of range are included in the Ponto-Mediterranean and Mediterranean elements. A hypothesis on the origin of the click beetles fauna of the area was presented. It was stated that the species that are climatic relicts (late Pleistocene and previous periods of Holocene) are very poorly represented in the fauna (2 species related to forest-steppe habitats: Porthmidius austriacus and Melanotus crassicollis). The species that are habitat relicts of natural forests (e.g. Lacon querceus, Limoniscus violaceus, Stenagostus rhombeus, Hypoganus inunctus, Ischnodes sanguinicollis, Brachygonus dubius, Ampedus cardinalis, Elater ferrugineus, Isorhipis melasoides) are much more numerous. Taking the above into consideration it was found that the fauna of click beetles of the Bielinek reserve has a specific, unique character and in this respect the reserve can be counted among the most valuable refugia of unique fauna in Poland, and probably also in Europe.

Badaniami objęto trzy grupy genetyczne indyków - w typie ciężkim Hybrid Large White (HLW) i Big-6 oraz średniociężkim indyki WAMA-3. W każdej grupie odchowywano 200 lamie i 50 samców. Do reprodukcji wybrano losowo z każdej grupy po 105 samic i 20 samców. Okres rozpłodu trwał 20 tygodni. Po zakończonym okresie wychowu (30 tyg.) nieco cięższe (o 0.56 kg) były indyczki HLW (12.16 kg) od BIG-6 (11.60 kg). Samce w tych grupach osiągnęły jednakową masę ciała (25.85 kg). Indyki średniociężkie WAMA-3 ważyły w tym wieku mniej - samice 9.15 kg, a samce - 21.84 kg. Indyki WAMA-3 niezależnie od płci spożywały w okresie wychowu najmniej paszy. Największe spożycie paszy odnotowano u samców (106.91 kg) i samic (53.08 kg) w grupie indyków BIG-6. Indyczki BIG-6 i WAMA-3 osiągnęły dojrzałość rozpłodową w 224 dniu życia, a HLW w 229. dniu. Średnie zapłodnienie jaj wynosiło u indyczek HLW - 89.6%, BIG-6 - 88.6% i WAMA - 91.8%. Szczyt nieśności w analizowanych stadach osiągnęły ptaki w 3.-4. tyg. produkcji. W ciągu 140 dni nieśności uzyskano od nioski stanu początkowego od 60.6 szt. jaj (HLW) do 73.8 szt. (BIG-6). Średnia liczba piskląt wylęgłych od jednej nioski, to 41.3 szt. w grupie WAMA-3, 39.2 szt. w grupie BIG-6 i 33.3 szt. w grupie HLW. Najwyższe zużycie paszy na produkcję 1 pisklęcia stwierdzono u indyków HLW (1607 g), a najniższe u WAMA-3 (1164 g).
