Descriptions. Black widow spider antivenin belongs to a group of medicines known as immunizing agents. It is used to treat patients with serious symptoms caused by the bites of the black widow spider. This medicine is to be given only by or under the direct supervision of a doctor.
They use their neurotoxic venom as a defense — delivering the most toxic spider bite in the U.S. The venom of a female black widow is 15 times stronger than a rattlesnake's, and they have the ability to paralyze large prey.
α-Latrotoxin is a presynaptic neurotoxin isolated from the venom of the black widow spider Latrodectus tredecimguttatus. It exerts toxic effects in the vertebrate central nervous system by depolarizing neurons, by increasing [Ca2+]i and by stimulating uncontrolled exocytosis of neurotransmitters from nerve terminals.
Indications and Usage for Antivenin Black Widow Spider. Antivenin (Latrodectus mactans) is used to treat patients with symptoms due to bites by the black widow spider (Latrodectus mactans).
The black widow spider makes a venom that affects your nervous system. Some people are slightly affected by it, but others may have a serious response. You may feel serious pain, burning, swelling, and redness at the site.
Can I still expect a bodily reaction? If you happen to eat a venomous spider, say a Black Widow or Brown Recluse, which both have medically significant venom, and you get it down to your stomach without getting bit, the hydrochloric acid in your stomach will render the toxic venom harmless.
Sydney funnel-web spider. According to the Guinness World Records, the Sydney funnel-web spider, Atrax robustus, is the most dangerous spider to humans in the world. Native to Australia, this poisonous spider is found in moist habitats such as under logs or in gardens.
The venom is collected from the tips of the fangs in a glass capillary tube. The spider regurgitates digestive fluids (it vomits) during milking. The vomit dilutes or even destroys the venom, so the vomit must be removed from the spider's mouth using a tiny suction device.
Adult male and female black widows live solitary lives, meeting only to breed. The female black widow lays approximately 200 eggs. The eggs incubate for some 20 days in a small, round papery sac that's attached to the mother's web. After hatching, the baby spiders stay in the cocoon for up to one month.
The venom from a black widow spider is poisonous. Symptoms of a reaction to the venom start about 30 minutes after the bite. Symptoms are usually mild and stop within a few days, but severe symptoms that last several days are possible. Venom can spread from the bite to other parts of your body.
Red Dust is a gas used to free mind controlled victims from their subjugation. Yelena Belova and Natasha Romanoff used the Red Dust to free the Black Widows and Taskmaster from Dreykov's control.
If a black widow bite is causing severe pain or life-threatening symptoms, your doctor might recommend antivenom, which is usually given through a vein (intravenously). Symptoms usually ease within about 30 minutes of receiving the antivenom.
A black widow bite usually feels like a pinprick, though some individuals feel nothing at all. Within the first hour of a bite, individuals may feel dull muscle pain throughout the entire body. The bite site later swells and turns red, forming a target-shaped lesion.

She, like other Black Widow assassins created by the dreaded Red Room, was subjected to a forced hysterectomy during training, and therefore cannot menstruate.
A woman who kills one or more of her lovers. A female suicide bomber, sometimes one intending to avenge her husband who was killed.
Natasha Romanoff was born in the Soviet Union as Natalia Alianovna Romanova (Наталия Альяновна Романова). Although her exact parentage is unknown, it is rumored that she is related to the late Romanov dynasty—the former rulers of Russia—but those claims have so far been unproven.
Moore found that the black widow uses two kinds of silk for scaffolding. One can stretch an extra 25% of its length before breaking and is twice as strong as the orb spider's dragline.
A female black widow spider can store the sperm from one mate and use it throughout her lifetime.
Black widows are the most venomous spider in North America. Their venom is about 15 times stronger than rattlesnake venom, and uses a chemical called alpha-latrotoxin to overwhelm nerve cells and cause immense pain.
The prognosis for black widow bites is good. Most pain and systemic symptomatology are self-limited. Although patients may encounter long-term pain or muscle spasms after black widow bites, this phenomenon is rare. Similarly, systemic toxicity, including abdominal pain and autonomic dysfunction, is usually temporary.
Some black widow bites cause such extreme pain that it's mistaken for appendicitis or a heart attack. This kind of intense pain is treated with narcotics. Muscle cramps are treated with muscle relaxants. Once in a while, black widow bites can cause trouble breathing.
1. Sydney funnel-web (Atrax robustus) With highly toxic venom produced in large amounts and large fangs to inject it, the Sydney funnel-web is without a doubt the deadliest spider in Australia, and possibly the world.
The Sydney funnelweb spider Atrax robustus, is considered to be the world's most dangerous spider. It is found within a 100 km diameter circle around Sydney. No deaths have occurred since the advent of an antivenom in 1981. Males wander at night in spring and summer in search of females.
The funnel web “classically speaking” is considered the world's deadliest spider because it “kills so quickly”. “In terms of speed of death, in Australia we say funnel web, 15 minutes, no sweat,” Raven said. “With a funnel web bite to the torso, you're dead.
