The genus Campylobacter  is of great importance to public health because it includes several species that may cause diarrhoea. Poultry and poultry products are known as important sources of human campylobacteriosis. In this study, during the autumn months of 2005, a total of 100 samples from poultry carcasses, representing 20 broiler flocks were obtained by rinse test, after the chilling stage ...

The southern Neotropical genus Anahi Martínez is comprehensively revised and now includes three species: A. dentata Ocampo Ruiz-Manzanos new species, A. guaraniticus Martínez, and A. oblivia Ocampo Ruiz-Manzanos new species. The new species extend the distribution of the genus from Paraguay and Bolivia to Argentina. A. guaraniticus is redescribed and the characters that define the genus are ext...

The common zero locus of a set of multivariate polynomials (with complex coefficients) determines an algebraic set. Any algebraic set can be decomposed into a union of irreducible components. Given a one dimensional irreducible component, i.e. a curve, it is useful to understand its invariants. The most important invariants of a curve are the degree, the arithmetic genus and the geometric genus...

The genus Alnus (Betulaceae) is comprised of more than 40 species. Many species of this genus have a long history of use in folk medicines. Phytochemical investigations have revealed the presence of diarylheptanoids, polyphenols, flavonoids, terpenoids, steroids and other compounds. Diarylheptanoids, natural products with a 1,7-diphenylheptane structural skeleton, are the dominant constituents ...

during the period of april to november 1994, an investigation was carried out on fauna of phlebotominac in ilam province, west of iran. about 12000 sandflies were caught by sticky trap, light trap and aspirator from different ecological regions and were identified. these sandflies consist of 22 species (11 species from the genus phlebotomus: ph. paptasi, ph.sergenti, ph.alexandri, ph.rnajor, ph...

Cellobiose dehydrogenase (CDH EC.1.1.5.1) is an extracellular enzyme that mainly produced by wood-degrading fungi. It oxidizes cellobiose to cellobionolactone using a wide spectrum of electron acceptors. The key roles of CDH in growth, metabolism, and some other important cellular processes such as cellulose degradation in fungi have been noted. Since the demands for finding new sources of CDH ...

during a faunistic survey of natural enemies of spider mites of genus tetranychus in mashhad and vicinity, a predatory gall midge species belonging to the family cecidomyiidae was collected and identified as feltiella acarisuga vallot. f. acarisuga is one of the ten species in the genus feltiella and an important biological control agent of tetranychid mites has previously been reported from va...

In this paper we construct families of hyperbolic knots with free genus one, whose complements have arbitrarily large volume. This implies that these knots have free genus one but arbitrarily large canonical genus.

The stiletto fly genus Eupsilocephala Kröber is a member of the Taenogera genus-group endemic to Australia. Two new species of this rarely collected genus, Eupsilocephala albodorsalis sp. nov. and Eupsilocephala sulphurea sp. nov., are described.
