  1. Ascaris lumbricoides: Morphology, life cycle, Pathogenesis, lab diagnosis and Treatment. Ascaris lumbricoides is an intestinal round worm. It is the largest intestinal nematode to infect Human. The adult worm lives in small intestine and grow to a length of more than 30 cm. Human is only the natural host and reservoir of infection
  2. The fourth stage larvae reach the pharynx through trachea and finally reach the gut where it attains adult stage. The average life span of this worm is 9 to 12 months in man. Disease : Ascaris lumbricoides causes ascariasis which is more in children than in the adult persons. In the intestine of man these worms take the digested food materials
  3. Ascaris species are very large (adult females: 20 to 35 cm; adult males: 15 to 30 cm) nematodes (roundworms) that parasitize the human intestine. A. lumbricoides is the primary species involved in human infections globally, but Ascaris derived from pigs (often referred to as A. suum) may also infect humans. These two parasites are very closely related, and hybrids have been identified; thus, their status as distinct, reproductively isolated species is a contentious topic

Ascaris lumbricoides is one of the largest and most common parasites found in humans. The adult females of this species can measure up to 45 cm long (males are generally shorter), and it is estimated that 25% of the world's population is infected with this nematode. The adult worms live in the small intestine and eggs are passed in the feces Surgery may be needed to treat serious complications caused by some of these parasites.

Adult worms live in the small intestine Fertilized and unfertilized eggs are passed in the feces unfertilized eggs are not infective when ingested fertilized eggs are infective Embryonated eggs become infective after about 2.5 weeks (under optimum conditions, several weeks if suboptimal) Infective eggs are swallowed The larvae hatch and invade the intestinal barrier The Life Cycle. Ascaris lumbricoides, or roundworm, infections in humans occur when an ingested infective egg releases a larval worm that penetrates the wall of the duodenum and enters the blood stream.From here, it is carried to the liver and heart, and enters pulmonary circulation to break free in the alveoli, where it grows and molts The entire life cycle of ascaris lumbricoides would last for around 2 - 3 months whereas, the adult worms can live up to a year producing millions of eggs.
