Immune thrombocytopenia possibly triggered by multiple tick bites.
Rev Inst Med Trop Sao Paulo

Hospital Militar Central, Servicio de Infectología, Bogotá, Colombia.
Immune thrombocytopenia (ITP) is an autoimmune hematological condition characterized by a markedly isolated decrease in platelets without any apparent associated clinical conditions, resulting in bleeding and bruising of the skin, mucous membranes, and major organs. It is often triggered by preceding illness or several immune stimulants such as immunizations, infections, allergic reactions, among others. While uncommon, arthropod bites can trigger acute ITP.

Bee venom (BV) represents a promising natural alternative to conventional antibiotics, particularly significant given its broad-spectrum antimicrobial activity and potential to address the growing challenge of antimicrobial resistance. The prevalence of antimicrobial-resistant microorganisms (AMR) is a global burden that affects human health and the economies of different countries. As a result, several scientific communities around the world are searching for safe alternatives to antibiotics.

Background: Bee venom consists of more than 50 % melittin (MLT), which has anti-cancer, anti-inflammatory, and antimicrobial properties. Bee venom also contains toxic components such as phospholipase A2 (PLA2) and hyaluronidase (HYA), which cause allergic reactions, so the toxic components must be removed to use MLT. In previous studies, analytical methods were used to separate MLT.

Background: Melittin, a major peptide component of bee venom, has demonstrated promising anti-cancer activity across various preclinical cell models, making it a potential candidate for cancer therapy. However, its molecular mechanisms, particularly in ovarian cancer, remain largely unexplored. Ovarian cancer is a life-threatening gynecological malignancy with poor clinical outcomes and limited treatment options.

The rapid and reliable detection of pathogenic bacteria remains a significant challenge in clinical microbiology. Consequently, the demand for simple and rapid techniques, such as antimicrobial peptide (AMP)-based sensors, has recently increased as an alternative to traditional methods. Melittin, a broad-spectrum AMP, rapidly associates with the cell membranes of various gram-positive and gram-negative bacteria.
