Plasmodium falciparum infections are known for having very pleomorphic (variable in shape) older trophozoites compared to the other Plasmodium species that cause malaria in humans. P. falciparum is the most severe form of malaria and can lead to complications and high mortality if not treated promptly and effectively.

Myiasis is the condition caused by the infestation of the skin, wounds, or body cavities of a living host by fly larvae (maggots) that feed on the host’s dead or living tissue, liquid body substances, or ingested food. It can occur in tropical and subtropical areas, as well as temperate zones.

A. Loxosceles

Loxosceles spiders, commonly known as brown recluse spiders, have venom that can cause a reaction leading to necrosis or gangrene at the bite site. The venom contains enzymes that can destroy skin tissues and cause a condition known as loxoscelism, which is characterized by a localized necrotic wound.

Latrodectus spiders, known as black widow spiders, produce venom that is neurotoxic, affecting the nervous system and causing symptoms such as pain, muscle cramps, and spasms, rather than necrotic wounds.
