Pathology of sarcoptic mange in red foxes (Vulpes vulpes): macroscopic and histologic characterization of three disease stages.

Sarcoptic mange is a highly contagious skin disease that can have a devastating impact on affected wild mammal populations. There are notable variations in the clinical and pathologic picture of sarcoptic mange among species and among conspecifics. However, the origin of these variations is unclear.

Rapid diagnosis and quantification of Francisella tularensis in organs of naturally infected common squirrel monkeys (Saimiri sciureus).

Francisella tularensis, a small Gram-negative facultative intracellular bacterium, is the causative agent of tularaemia, a severe zoonotic disease transmitted to humans mostly by vectors such as ticks, flies and mosquitoes. The disease is endemic in many parts of the northern hemisphere. Among animals, the most affected species belong to rodents and lagomorphs, in particular hares.

Transient Expression of a Major Ampullate Spidroin 1 Gene Fragment from sp. in Mammalian Cells.

Spider silk possesses extraordinary and unsurpassed mechanical properties and several attempts have been made to artificially produce spider silk in order to manufacture strong and light engineering composites. In the field of oncology, recombinant spider silk has the potential to be used as a biomaterial for bone replacement after tumour surgery. In this study, a 636-base pair gene fragment, coding for a part of major ampullate spidroin 1 from the African spider, Euprosthenops sp.

Spider silk proteins--mechanical property and gene sequence.

Spiders spin up to seven different types of silk and each type possesses different mechanical properties. The reports on base sequences of spider silk protein genes have gained importance as the mechanical properties of silk fibers have been revealed. This review aims to link recent molecular data, often translated into amino acid sequences and predicted three dimensional structural motifs, to known mechanical properties.
