Selected to survive and kill: Tityus serrulatus, the Brazilian yellow scorpion. [PDF]

PLoS ONE, 2019
Annually, more than 1.2 million scorpion stings and more than 3,000 deaths occur worldwide. Tityus serrulatus Lutz and Mello, 1922 (Scorpiones, Buthidae) is the most medically relevant species in Brazil where it is spreading rapidly and causing over 90 ...

Inhibition of Tityus serrulatus venom hyaluronidase affects venom biodistribution. [PDF]

PLoS Neglected Tropical Diseases, 2019
BackgroundThe hyaluronidase enzyme is generally known as a spreading factor in animal venoms. Although its activity has been demonstrated in several organisms, a deeper knowledge about hyaluronidase and the venom spreading process from the bite/sting ...

Immunomodulatory activity of Tityus serrulatus scorpion venom on human T lymphocytes. [PDF]

J Venom Anim Toxins Incl Trop Dis, 2015
Tityus serrulatus scorpion venom (TsV) contains toxins that act on K(+) and Na(+) channels and account for the venom's toxic effects. TsV can activate murine peritoneal macrophages, but its effects on human lymphocytes have been poorly investigated. Considering that lymphocytes may play an important role in envenomation, we assessed whether TsV affects

The nociceptive response induced by different classes of Tityus serrulatus neurotoxins: The important role of Ts5 in venom-induced nociception [PDF]

PLoS Neglected Tropical Diseases, 2023
Scorpion sting envenomations (SSE) are feared by the intense pain that they produce in victims. Pain from SSE is triggered mainly by the presence of neurotoxins in the scorpion venom that modulates voltage-gated ion channels.

Tityus serrulatus Scorpion Venom-Induced Nociceptive Responses Depend on TRPV1, Immune Cells, and Pro-Inflammatory Cytokines [PDF]

Toxins
For centuries, researchers have been fascinated by the composition of scorpion venom and its local and systemic effects on humans. During a sting, scorpions inject peptides and proteins that can affect immune cells and neurons.

First report of scorpionism caused by Tityus serrulatus, described by Lutz and Mello, 1922 (Scorpiones, Buthidae), a species non-native to the state of Pará, Brazilian Amazon [PDF]

Revista da Sociedade Brasileira de Medicina Tropical, 2020
This reports a case of scorpionism caused by Tityus serrulatus. A male adult was stung while unloading bananas at the supply center in Belém, Pará, Brazil. The bananas originated in another state (Bahia) and were brought to Belém by truck.

Understanding the complexity of Tityus serrulatus venom: A focus on high molecular weight components [PDF]

Journal of Venomous Animals and Toxins including Tropical Diseases
Tityus serrulatus scorpion is responsible for a significant number of envenomings in Brazil, ranging from mild to severe, and in some cases, leading to fatalities. While supportive care is the primary treatment modality, moderate and severe cases require

What do we know about some of the most conspicuous scorpion species of the genus Tityus? A historical approach [PDF]

Journal of Venomous Animals and Toxins including Tropical Diseases, 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 ...
