Histology and ultrastructure of the gut epithelium of the neotenic cave salamander, Proteus anguinus (Amphibia, Caudata).
Histological, histochemical, and ultrastructural features of the gut of the European endemic cave salamander Proteus anguinus were studied. The gut is a relatively undifferentiated muscular tube lined with a simple columnar epithelium containing numerous goblet cells. The mucosa and underlying lamina propria/submucosa are elevated into a number of high longitudinal folds projecting into the lum...
متن کاملBacteriophage typing of Proteus mirabilis, Proteus vulgaris, and Proteus morganii.
A bacteriphage typing scheme for differentiating Proteus isolated from clinical specimens was developed. Twenty-one distinct patterns of lysis were seen when 15 bacteriophages isolated on 8 Proteus mirabilis, 1 P. vulgaris, and 1 P. morganii were used to type 162 of 189 (85.7%) P. mirabilis and P. vulgaris isolates. Seven phages isolated on 3 P. morganii were used to type 13 of 19 (68.4%) P. mo...
متن کاملExtreme lifespan of the human fish (Proteus anguinus): a challenge for ageing mechanisms.
Theories of extreme lifespan evolution in vertebrates commonly implicate large size and predator-free environments together with physiological characteristics like low metabolism and high protection against oxidative damages. Here, we show that the 'human fish' (olm, Proteus anguinus), a small cave salamander (weighing 15-20 g), has evolved an extreme life-history strategy with a predicted maxi...
متن کاملMonitoring health and reproductive status of olms (Proteus anguinus) by ultrasound
The olm (Proteus anguinus) is a troglomorphic, neotenous amphibian with extraordinary life expectancy and unique adaptations that deserve further investigation. A low reproductive rate and habitat decline render it threatened by extinction. Establishing captive populations for maintenance and artificial breeding may one day become crucial to the species. Longitudinal, in-vivo assessment of inne...
متن کاملPlasmid Pattern of Biofilm Producing Proteus mirabilis and Proteus vulgaris among Clinical Isolates in Kerman University Hospitals during 2011-2012
Background & Aims: Emergence of biofilm producing Proteus strains created a serious problem in the treatment of catheter-associated urinary tract infections. The aim of this research was to study biofilm production and plasmid pattern of proteus strains associated with Urinary tract infection. Methods: A total of 88 strains of Proteus were isolated from samples collected in hospitals of Kerman/...
