What do we know about some of the most conspicuous scorpion species of the genus Tityus? A historical approach [PDF]
, 2015 In the present study, comments are proposed on historical aspects of the most conspicuous scorpion species of the genus Tityus found in Brazil. Both Tityus bahiensis (Perty) and Tityus serrulatus Lutz & Mello are better known for their infamous ...

A novel K+ channel blocking toxin from Tityus discrepans scorpion venom [PDF]
, 1999 A novel toxin (TdK1) was purified from the venom of the scorpion Tityus discrepans, sequenced and functionally characterized. It contains 37 amino acid residues and blocks reversible the shakerB K+ channel expressed in SF9 cells with a Kd in the order of

Cardiorespiratory evaluation of juvenile rats experimentally envenomed with Tityus serrulatus venom [PDF]
Journal of Venomous Animals and Toxins including Tropical Diseases, 2010 Accidental envenomation caused by Tityus serrulatus scorpions is very common in Brazil and may result in serious cardiorespiratory alterations that are frequently fatal to children. In the present study, the effects of T. serrulatus venom on the cardiorespiratory system of recently weaned male Wistar rats were evaluated.

Genotoxicity evaluation induced by Tityus serrulatus scorpion venom in mice
Toxicon, 2017 Tityus serrulatus is the scorpion associated with the most severe cases of scorpion envenoming in Brazil. However, there are no studies reporting the genotoxic effects of this venom in natural or experimental envenomations. It is well known that DNA-damage responses are providing opportunities for improving disease detection and management.

A study of myonecrosis induced by the venom of the scorpion tityus serrulatus.
Histology and histopathology, 1987 The pathogenesis of skeletal muscle necrosis produced by Tityus Serrulatus venom was studied by means of light microscopy and electron microscopy. Wistar rats were inoculated subcutaneously, at some distance from the muscles under study, with a sublethal dose of scorpion venom. Samples were taken of the tibialis anterior muscles of both rear legs, 2, 7

Inter- and intrapopulational genetic variability of Tityus serrulatus (Scorpiones, Buthidae)
Acta Tropica, 2009 In Brazil, there are near 20 genera and almost 120 species of scorpions of which 95% reproduce sexually. Parthenogenetic reproduction, however, may also take place. To gain insight into useful molecular markers in parthenogenetic scorpion species, we studied DNA polymorphism using two molecular approaches: simple sequence repeat anchored polymerase ...
