Gaboon Viper
The black mamba (Dendroaspis polylepis) venom is primarily neurotoxic.
The venom contains a combination of neurotoxins, including:
1. Dendrotoxins: These are potent neurotoxins that can cause respiratory failure, cardiac arrest, and renal failure.
2. Fasciculins: These are muscle toxins that can cause muscle weakness, paralysis, and respiratory failure.
3. Calciseptine: This is a toxin that can cause muscle paralysis and respiratory failure.
The neurotoxins in black mamba venom work by blocking the release of neurotransmitters, such as acetylcholine, at the neuromuscular junction. This can lead to a range of symptoms, including:
- Respiratory failure
- Cardiac arrest
- Muscle weakness and paralysis
- Renal failure
- Seizures and coma
While the venom is primarily neurotoxic, it can also cause some cytotoxic effects, such as local tissue damage and necrosis. However, the neurotoxic effects are the primary cause of morbidity and mortality associated with black mamba bites.
It's worth noting that black mamba venom is highly toxic, with an LD50 (the dose required to kill 50% of test subjects) of around 0.25-0.5 mg/kg. However, with prompt medical treatment, including antivenom administration, the prognosis for black mamba bite victims is generally good.
​
​
The Berg adder (Bitis atropos) venom is primarily cytotoxic.
The venom contains a combination of enzymes and peptides that cause local tissue damage, necrosis, and inflammation. The cytotoxins in Berg adder venom work by:
1. Breaking down tissue membranes and causing cell lysis
2. Activating inflammatory pathways and causing edema
3. Damaging blood vessels and causing hemorrhaging
The cytotoxic effects of Berg adder venom can lead to a range of symptoms, including:
- Severe pain and swelling at the bite site
- Necrosis and gangrene
- Blistering and bruising
- Inflammation and edema
- Systemic complications, such as renal failure and cardiovascular instability
While the venom is primarily cytotoxic, it may also contain some neurotoxic components, which can cause systemic symptoms such as:
- Weakness and fatigue
- Dizziness and nausea
- Headache and fever
However, the neurotoxic effects are generally less pronounced than the cytotoxic effects, and the venom is not considered to be highly neurotoxic.
It's worth noting that the Berg adder is a venomous snake found in the mountainous regions of southern Africa, and its venom can cause significant morbidity and mortality if left untreated. Prompt medical treatment, including antivenom administration, is essential for managing Berg adder bites.

# Cytotoxic Effects
The venom also contains cytotoxins that can cause:
1. Local tissue damage and necrosis
2. Inflammation and edema
# Neurotoxic Effects
In addition to hemotoxic and cytotoxic effects, Boomslang venom may also contain neurotoxins that can cause:
1. Weakness and fatigue
2. Dizziness and nausea
3. Headache and fever
However, the neurotoxic effects are generally less pronounced than the hemotoxic and cytotoxic effects.
The Boomslang is a venomous snake found in sub-Saharan Africa, and its venom can cause significant morbidity and mortality if left untreated. Prompt medical treatment, including antivenom administration, is essential for managing Boomslang bites.

The neurotoxic effects of Forest Cobra venom can cause:
- Respiratory failure
- Muscle paralysis
- Weakness and fatigue
- Dizziness and nausea
- Headache and fever

The neurotoxic effects of Green Mamba venom can cause:
- Respiratory failure
- Muscle paralysis
- Weakness and fatigue
