Venoms and Toxins - Volume 2, Issue 1, 2022

Venom toxins have specific molecular targets that result in envenomated complications such as neurotoxicity. During evolution, the composition of the venom has been evolved synchronously with the evolution of molecular targets. Venom is an important tool for humans from two different perspectives; venom advantages and disadvantages. Meanwhile, clinical and pharmacological applications of venoms due to their specif Read More

A diversity of marine invertebrates, such as cnidarians are rich sources of large bio-active molecules. This chemo-diversity of bio-active compounds has a promising potential in several biotechnological and therapeutic applications. On the basis of a comparative bibliographic approach, we intend in this review to present and discuss an overview of: i) the diversity of marine invertebrates as a candidate for bio-active molecules prod Read More

Phospholipases A2 enzymes are found in many mammalian tissues and in animal venoms. Those present in bee venom (bvPLA2) and snake venom (svPLA2) have been studied more particularly for their biological activities of interest. Although they belong to the same family of secreted PLA2 (sPLA2), bvPLA2 and svPLA2 differ from a structural and functional point of view. In this review, we describe the morphological characte Read More

Background: Androctonus mauretanicus (Am ) is one of the most hazardous scorpions in Morocco and has a highly toxic venom responsible for severe cases of envenomation. However, few studies have focused on deciphering its proteic composition. Objectives: Herein, we aim to map out the complete proteome of the Am venom filtrate to highlight its complexity and the polymorphism of its toxic content. This, in turn, will l Read More

Background: Cholera is a life-threatening secretory diarrheal disease caused by Vibrio cholera bacterium. On the contrary, local and specific use of cholera toxin (CT) at a low concentration can cause controlled fluid secretion. In the study, we explored the secretory action of CT in the intestine of rats with acute renal failure (ARF). Methods: Closed intestinal loop experiments were performed in ARF rats treated with CT. Secreted flu Read More

Background: The development of antivenom or antidote requires the repetition of immunization of large animals, such as horses and goats, which ultimately releases the IgG immunoglobulin produced in the serum specimen. As snake venom involves a variety of proteins and enzymes getting administered into the animal, this process can inflict significant harm to the animal; therefore, choosing carriers that can deliver the lea Read More

Introduction: The health challenges associated with cassava products as a common staple food for approximately 70 % of Africans and part of Asia pose a looming danger due to Bacillus enterotoxins’ presence in the processing environment. Objective: This study investigated the presence of enterotoxigenic genes, namely, Bacillus cereus enterotoxin T (bceT), hemolysin bl (hblC, hblD), and non-haemolytic enterotoxin (nheA, n Read More
