Ecology and Life Cycle Patterns of Echinococcus Species.

Abstract: The genus Echinococcus is composed of eight generally recognized species and one genotypic cluster (Echinococcus canadensis cluster) that may in future be resolved into one to three species. For each species, we review existing information on transmission routes and life cycles in different geographical contexts and - where available - include basic biological information of parasites and hosts (e.g., susceptibility of host species). While some Echinococcus spp. are transmitted in life cycles that involve predominantly domestic animals (e.g., dog - livestock cycles), others are wildlife parasites that do or do not interact with domestic transmission. In many cases, life cycle patterns of the same parasite species differ according to geography. Simple life cycles contrast with transmission patterns that are highly complex, involving multihost systems that may include both domestic and wild mammals. Wildlife transmission may be primary or secondary, i.e., resulting from spillovers from domestic animals. For most of the species and regions, existing information does not yet permit a conclusive description of transmission systems. Such data, however, would be highly relevant, e.g., for anticipation of geographical changes of the presence and frequency of these parasites in a warming world, or for initiating evidence-based control strategies.

Phytochemical and nutritional significance of cactus pear

Abstract: This review discusses cactus pear fruit with special emphasis on its functional components. Besides their nutritional importance, their significance in plant physiology is also described. Opuntia sp. is characterized by high levels of amino acids, especially proline and taurine. The latter was recently re-evaluated in nutritional science as a conditional amino acid and was hitherto virtually unknown in plant tissues. Free amino compounds also take part in osmoregulation and play an important role in betaxanthin biosynthesis. In contrast to red beets, cactus pears offer a great palette of colour hues and therefore may be used as a food colouring free from certification. The mucilages in Opuntia sp. tissue are responsible for water retention and can be used as dietary fibre or food thickening agents. Low in acids, the fruit is suitable for use in dairy products. With readily absorbable sugars, high vitamin C and mineral content, as well as containing polyphenols, amino acids and having a pleasant flavour, cactus pear is tailor-made for functional food preparations.

Anaerobic Microbial Degradation of Hydrocarbons : from Enzymatic Reactions to the Environment

Abstract: Hydrocarbons are abundant in anoxic environments and pose biochemical challenges to their anaerobic degradation by microorganisms. Within the framework of the Priority Program 1319, investigations fun

Spectroscopic Properties of Organic Azo Compounds

Abstract: Azo compounds are characterized by a low-energy 1(n,π*) electronic state, which gives rise to a weak band at long wavelengths in the absorption spectrum. Coupling of this state with other low-lying molecular states is responsible for the high intensity of the “azo band” compared to other forbidden transitions, for its lack of vibrational structure, and for the inability of nearly all organic azo compounds to fluoresce.
