Study of Blood Parasites of the Three Snake Species in Iran: Natrix natrix, Natrix tessellata and Zamenis longissimus (Colubridae)

Infections with blood parasites are common phenomenon in reptiles from all over the world. Apicomplexan are the majority of blood parasites that frequently occur with high levels of parasitaemia in the snakes. The aim of this study was to determine the presence of blood parasites in some snakes Guilan province in the North of Iran. A total of 51 specimens of three snake species were captured in...

A glitch in the Natrix: cryptic presence of alien grass snakes in Switzerland

The difficulty to detect invasive species depends of numerous factors, such as morphological similarities with local taxa (Dubey et al., 2014), low densities (Fitzpatrick et al., 2009), cryptic behaviours (Mazzotti et al., 2015), or remote distribution ranges (Lass et al., 2002). In some circumstances, alien taxa hybridize with local ones resulting in individuals with intermediate phenotypes. T...

Enzyme histochemistry of skeletal muscle.

This is the first of three papers on the application of enzyme histochemical techniques to the study of developing and diseased muscle. This paper will deal with developing muscle in various laboratory animals, the second with developing human muscle, and the third with hereditary neurogenic atrophies in infancy and childhood. In 1678 Stefano Lorenzini had already observed that animal muscle co...
