The olive tree is a member of the Oleaceae family, which contains the genera Fraxinus, Forsythia, Forestiera, Ligustrum and Syringa, as well as the genus Olea. Commercial olives are products of the Olea europaea L. species. There are roughly 20 species of Olea found throughout tropical and subtropical regions of the world, but only O. europaea L. produces edible fruit. The fruit of olive trees ...

The speed of recovery of cell suspensions and biofilm populations of the ammonia oxidizer Nitrosomonas europaea, following starvation was determined. Stationary-phase cells, washed and resuspended in ammoniumfree inorganic medium, were starved for periods of up to 42 days, after which the medium was supplemented with ammonium and subsequent growth was monitored by measuring nitrite concentratio...

A papillomavirus was isolated from healthy epithelial tissue of two European moles (Talpa europaea) and the complete genomic sequence was determined. To our knowledge, this is the first papillomavirus to be isolated from a mole. Phylogenetic analysis shows it to be most closely related to viruses of the genus Kappapapillomavirus.

The complete genome sequence of Nova virus, a novel hantavirus isolated from a European mole (Talpa europaea) captured in central Poland, was determined. The availability of this sequence will facilitate the search for other mole-borne hantaviruses and will accelerate the acquisition of new knowledge about their phylogeography and evolutionary origin.

Cytochrome c oxidase has been purified from the ammonia oxidizing chemoautotroph Nitrosomonas europaea by ion-exchange chromatography in the presence of Triton X-100. The enzyme has absorption maxima at 420 and 592 nm in the resting state and at 444 and 598 nm in the dithionite-reduced form; optical extinction coefficient (598 nm minus 640 nm) = 21.9 cm-1 nM-1. The enzyme has approximately 11 n...

BACKGROUND A new subcutaneous specific immunotherapy (SCIT) product adsorbed on aluminium hydroxide has been developed with a short and simplified up-dosing phase, containing a biologically standardized allergen pollen extract from Olea europaea. OBJECTIVE To assess the tolerability profile of the updosing phase and its immunological effect, in terms of specific IgG4 and IgE levels and immedi...

We found in the environmental strain Nitrosomonas europaea a chromosomal integron-like structure with an integrase gene, intI(Neu). We have tested the capacity of the IntINeu integrase to excise and integrate several resistance gene cassettes. The results allow us to consider IntINeu a new functional integron integrase.
