Epididymite,M. S. T. et Fertilité

Before the antibiotic’s era, the clinicians have shown the relation between epididymitis and Infertility. At the moment, venerial diseases are the principal cause of Epididymitis by the young man. The early diagnosis of the urethral infection (acute or not) associated with a suitable antibiotherapy will allow to protect the fertility.

Ephemerella readeri Müll. Hal. (Physcomitrella readeri (Müll. Hal.) I.G. Stone & G.A.M. Scott,Funariidae, Bryophyta): a genus and species new to Europe

Abstract

A morphological and molecular analysis of a Physcomitrella, collected from a reservoir margin in the north of England, revealed this to be P. readeri, a species new to Europe. The present study clarifies previous confusion over the taxonomy of P. readeri showing it to be clearly distinct in both sporophytic and gametophytic characters from P. patens and uniform across its world range from England to USA, Japan and Australasia. While phylograms of the ITS1 region from both the Physcomitrella species, Physcomitrium pyriforme (Hedw.) Bruch & Schimp., Enthosthodon attenuatus (Dicks.) Bryhn and Funaria hygrometrica Hedw., place the first two in separate clades, in ITS2 phylograms they occur as sister taxa. This, together with previous genealogical studies on the speciation history of the Physcomitrella–Physcomitrium species complex, and morphology, suggests that generic rank is appropriate for P. readeri. We therefore reinstate the original name Ephemerella readeri Müll. Hal. Recent records at several reservoirs in England indicate that E. readeri may be native to UK, though remarkable congruence in ITS1 with Australian plants also suggests recent arrival as an alternative possibility.
