What condition can result from bites of loxosceles spiders?

The condition that results from bites of loxosceles spiders is necrotic arachnidism. This term specifically refers to the severe tissue necrosis that can occur following a bite from certain species of the Loxosceles genus, commonly known as brown recluse spiders.

When a loxosceles spider bites a human, it injects venom that contains enzymes and proteins capable of destroying tissue around the bite site. This can lead to significant skin damage, ulceration, and necrosis, making timely medical treatment essential to manage the effects of the bite.

The other conditions listed do not relate directly to loxosceles spider bites. Acute arachnitis refers to inflammation of the arachnoid layer of the meninges and is not associated with spider bites. Arachnoiditis is an inflammatory condition affecting the arachnoid membrane in the central nervous system and does not stem from arachnid bites. Chronic arachnodermatitis relates to long-term skin inflammation and is not directly linked to spider bites either. Therefore, necrotic arachnidism is the only accurate choice concerning the effects of loxosceles spider bites.
