Helminthiasis :

Helminthiasis Infestation with or disease caused by parasitic worms. Organisms that live in the Intestines of Human Beings and are Harmful to human host.

Intestinal Nematodes:

Intestinal Nematodes Worms “ Lugay ”

Helminthiasis or Intestinal Nematode Infestation:

Helminthiasis or Intestinal Nematode Infestation Affects more than 1 billion people worldwide. Most Common in Tropical Countries with Poor Fecal Sanitation.

Helminthiasis or Intestinal Nematode Infestation:

Helminthiasis or Intestinal Nematode Infestation Contributes greatly to Malnutrition and Poor Academic Performance in School Children. Poor Physical Development. Diminished Working Capacity.

Three Most Common Intestinal Nematodes:

Three Most Common Intestinal Nematodes Ascaris lumbricoides Hookworm Trichuris trichura

Ascaris lumbricoides:

Ascaris lumbricoides

Ascaris lumbricoides:

Ascaris lumbricoides The Largest Intestinal Nematode parasite of Humans Adult Male 10 to 31 cms in length Adult Female 22 to 40 cms in length

Ascaris lumbricoides:

Ascaris lumbricoides 2 -3 Months elapse before initial infection and egg production. Lifespan of 1 to 2 years. Female produce 240,000 eggs/day

Ascaris lumbricoides:

Ascaris lumbricoides Most Common Roundworm affecting Human Beings Endemic Worlwide Very Common in South East Asia – Philippines.

Ascaris lumbricoides epidemiology:

Ascaris lumbricoides epidemiology Egg in the soil is infective stage. Eggs are transmitted via hand to mouth Eggs are resistant to chemical disinfectants and can withstand temporary immersion in strong chemicals.

Ascaris lumbricoides:

Ascaris lumbricoides Adult Worm location in the Lumen of Jejunum. Infection is most Common in 5 to 9 year old age group. Pre – school and young school children harbor the most infection.

Ascaris lumbricoides:

Ascaris lumbricoides Usual infection consists of 5 to 10 adult worms Most frequent complaint is vague abdominal pain

Ascaris lumbricoides:

Ascaris lumbricoides Children affected with Ascariasis do not gain weight normally Food is consumed by the worms. Adverse effect upon nutritional state and mental development of school children.

Ascariasis Signs and Symptoms:

Ascariasis Signs and Symptoms Lung Stage of Larval migration non - productive cough, burning substernal pain aggravated by coughing or deep inspiration .

Ascaris lumbricoides:

Ascaris lumbricoides Blood Streaked Sputum Hemorrhagic Pneumonitis

Ascaris lumbricoides:

Ascaris lumbricoides Fever

Ascaris lumbricoides complications:

Ascaris lumbricoides complications Intestines Usually Asymptomatic Large Infections – Bolus Intestinal Obstruction Perforation

Hookworm:

Hookworm

Hookworm:

Hookworm 2 Hookworm species infective to humans Ancyclostoma doudenale Necator americanus Most infected humans are Asymptomatic Heavy worm burden, prolonged infection, malnutrition causes Iron Deficiency Anemia

Hookworm:

Hookworm Ancyclostoma doudenale produce 20,000 eggs/day Necator americanus produce 10,000 eggs/day Eggs are deposited in soil. Eggs hatch and Develop to Rhabditiform larvae After 1 week Develop to Filariform larvae – Infective Stage

Hookworm:

Hookworm Penetrate through skin. Reach the lungs Penetrate the alveoli Invade the Upper airways Coughed and Swallowed Develop in Small intestine Time Period: 6 to 8 Weeks Note: Larvae of Ancyclostoma doudenale can develop directly if swallowed

Hookworms:

Hookworms Adult Hookworms grow up to 1 cm long Attach to mucosa of small intestine Ancyclostoma doudenale Suck up to 0.2 ml of blood per day Necator americanus suck up to 0.03 ml of blood per day

Hookworms:

Hookworms Lifespan up to 10 years Ancyclostoma doudenale : 6 to 8 years Necator americanus : 2 to 5 years

Hookworm:

Hookworm Female hookworm can produce eggs within 5 to 6 weeks after initial infection

Hookworm epidemiology:

Hookworm epidemiology Ancylostoma doudenale prevalent in southern Europe, North Asia N. americanus is the predominant species in the western hemisphere and equatorial Africa. The two species overlap in many tropical regions, particularly Southeast Asia.

Hookworm epidemiology:

Hookworm epidemiology Older children have the highest incidence and greatest intensity of hookworm infection. In rural areas where fields are fertilized with human feces, older working adults also may be heavily affected.

Clinical Features:

Clinical Features Most hookworm infections are asymptomatic. Infective larvae may provoke pruritic maculopapular dermatitis ("ground itch")

Clinical Features:

Clinical Features The major consequence of chronic hookworm infection is iron deficiency. weakness shortness of breath.

Clinical Features:

Clinical Features Larvae migrating through the lungs occasionally cause mild transient pneumonitis .

Clinical features:

Clinical features In the early intestinal phase, infected persons may develop epigastric pain Diarrhea Abdominal pain

Trichuris trichura:

Trichuris trichura

Trichuriasis:

Trichuriasis Most infections with the Trichuris trichiura are asymptomatic. Whipworm is distributed globally in the tropics and subtropics Most common among poor children from resource-poor regions of the world.

Trichuriasis:

Trichuriasis heavy infections may cause gastrointestinal symptoms. Like the other soil-transmitted helminths

Life Cycle :

Life Cycle Adult Trichuris worms reside in the colon and cecum Embed in the superficial mucosa. Thousands of eggs laid daily by adult female worms pass with the feces and mature in the soil.

Life Cycle:

Life Cycle Eggs are ingested Eggs hatch in the duodenum, Larvae mature in the small intestine. Migrate to the large bowel. The entire cycle takes ~3 months. Adult worms may live for several years.

In Summary:

ACTION (HOW DOES MEBENDAZOLE KILL THE WORM?) :

ACTION (HOW DOES MEBENDAZOLE KILL THE WORM?) Once ingested by the WORM, Mebendazole interferes with cellular tubulin formation in the WORM INTESTINE by specifically binding to the TUBULIN and causing ultrastructural degenerative changes in the intestine. Disrupts GLUCOSE UPTAKE and other Nutrients in worm intestine STOPS the DIGESTIVE FUNCTIONS OF THE WORM
