Roundworm (Female) - Ascaris lumbricoides
Ascaris lumbricoides is a large roundworm that infects humans. It grows to 35 cm (14 in)!!
It causes ascariasis, which is a Neglected Tropical Disease (NTG). Worldwide, approximately 1 billion people are infected with this nematode, with infection being more prevalent in tropical areas where sanitation is poor. It infects humans via the fecal-oral route...eggs are shed in feces and then get ingested. Hygiene is crucial to preventing the spread of this disease because it is one of the most difficult pathogens in the world to kill (the eggs can survive several years!).
