Brown recluse spider bites.

BACKGROUND Brown recluse spider bites are a serious medical problem in the southeastern United States. Although most bites are asymptomatic, envenomation can result in a constellation of systemic symptoms referred to as loxoscelism. Patients can also develop necrotic skin ulcers (necrotic arachnidism). These ulcers are often difficult to heal and can require skin grafting or amputation of the b...

Osteomyelitis of the Mandibular Symphysis Caused by Brown Recluse Spider Bite

BACKGROUND Brown recluse spider bites cause significant trauma via their tissue toxic venom. Diagnosis of these injuries and envenomation is difficult and many times presumptive. Treatment is varied and dependent upon presentation and course of injury. MATERIALS AND METHODS We present a case of a previously unreported incidence of osteomyelitis of the mandible as a result of a brown recluse s...

Passive hemagglutination inhibition test for diagnosis of brown recluse spider bite envenomation.

Our goal was to recreate a passive hemagglutination inhibition (PHAI) test to diagnose brown recluse spider (BRS; Loxosceles reclusa) bite envenomation for treatment trials. Guinea pigs received intradermal injections of concentrated spider venom from the following species: Loxosceles reclusa, Argiope aurantia, Argiope trifasciata, Phidippus audax, and Lycosa frondicola. Skin lesion exudate was...
