Bacterial phospholipases C with dual activity: phosphatidylcholinesterase and sphingomyelinase
The aim of this review is to discuss similarities and differences among the most explored bacterial enzymes that have both phospholipase C and sphingomyelinase C activities. The structural aspects of three of those enzymes, their substrate specificity, and in silico substrate docking analysis are discussed, as well as their mechanisms of toxicity in ...

Local Cytotoxic Effects in Cobra Envenoming: A Pilot Study
The cobra (genus Naja (N.)) is one of the most common venomous snakes. Due to its frequency and deadly complications of muscle paralysis, local necrosis, and chronic musculoskeletal disability, it should not be ignored.

Diclofenac enhances the sensitivity of methicillin‐resistant Staphylococcus aureus toward the β‐lactam antibiotics, which help to circumvent drug resistance and improve the antibacterial efficacy of conventional antibiotics. Besides, murine implant infection models show that diclofenac combined with oxacillin, can alleviate MRSA infections. Mechanistic

Insights into brown spider and loxoscelism [PDF]
Loxosceles is a genus of cosmopolitan spiders comprising several species, and popularly known as brown spiders or brown recluses. Brown spider bites can cause dermonecrotic lesions and systemic reactions known as loxoscelism.

Identification and validation of a linear protective neutralizing epitope in the β-pore domain of alpha toxin. [PDF]
The plethora of virulence factors associated with Staphylococcus aureus make this bacterium an attractive candidate for a molecularly-designed epitope-focused vaccine.

Loxosceles Sphingomyelinase Induces Complement-Dependent Dermonecrosis, Neutrophil Infiltration, and Endogenous Gelatinase Expression [PDF]
Envenomation by the spider Loxosceles can result in dermonecrosis and severe ulceration. Our aim was to investigate the role of the complement system and of the endogenous metalloproteinases in the initiation of the pathology of dermonecrosis ...

Envenomation by Loxosceles bites is characterized by dermonecrotic and/or systemic features that lead to several clinical signs and symptoms called loxoscelism. Dermonecrotic lesions are preceded by thrombosis of the dermal plexus.

Phospholipase D toxins of brown spider venom convert lysophosphatidylcholine and sphingomyelin to cyclic phosphates. [PDF]
Venoms of brown spiders in the genus Loxosceles contain phospholipase D enzyme toxins that can cause severe dermonecrosis and even death in humans.

Engineered nanoparticles bind elapid snake venom toxins and inhibit venom-induced dermonecrosis. [PDF]
Envenomings by snakebites constitute a serious and challenging global health issue. The mainstay in the therapy of snakebite envenomings is the parenteral administration of animal-derived antivenoms. Significantly, antivenoms are only partially effective
