Ryan, in Principles and Practice of Pediatric Infectious Diseases (Fifth Edition), 2018 Pyrantel Pamoate. LugolвЂ™s iodine (1% povidine iodine 10,000 ppm) may be used to kill hookworm larvae on exposed skin.Edward T. americanus larvae within five minutes and to kill all such larvae within 10 minutes, making ethanol a suitable surface disinfectant. In vitro exposure to 70% ethanol has been shown to kill 95.6% of 45 infective N. Appropriate PPE (gloves, gown) should always be worn to minimize the risk of transdermal penetration when working with stool specimens or larval cultures. Standard protocols apply for the handling of stool specimens. For quantitative assessments of infection, various methods such as the Kato-Katz, FLOTAC and Mini-FLOTAC may be used. Where concentration procedures are not available, a direct wet mount examination of the specimen is adequate for detecting moderate to heavy infections. Concentrate using the formalinвЂ“ethyl acetate sedimentation technique.Microscopic identification of eggs in the stool is the most common method for diagnosing hookworm infection. Patients have reported vague gastrointestinal disturbances and eosinophilia (sometimes referred to as Wakana syndrome) following peroral infection. Other clinical manifestations of hookworm infection include an urticarial dermal reaction (вЂњground itchвЂќ) associated with filariform (е…ѓ) larvae penetration, and respiratory involvement including eosinophilic pneumonia may be observed may occur during larval pulmonary migration A second urticarial rash may subsequently develop during pulmonary migration. In severe cases, protein malnutrition from chronic plasma protein loss has been reported. Occult blood in the stool may also be seen in heavy infections. Iron deficiency anemia caused by blood loss at the site of intestinal attachment of adult worms may occur especially in heavy infections. Attachment of the hookworms to the intestinal wall may stimulate abdominal pain, nausea, and anorexia. Intestinal hookworm infections are commonly asymptomatic.

However, the full extent of its geographic occurrence is not completely characterized. ceylanicum is highly endemic throughout much of Southeast Asia and the Pacific Islands, and also has been reported from Australia, Japan, South Africa, Madagascar, Suriname, Guyana, and the UAE it appears to be absent from Europe and North America. duodenale is found in the Middle East, North Africa, and northern India.ДЄ. americanus is found in south India and predominates in the Americas, while only A. Both Necator americanus and Ancylostoma duodenale are found in Africa, Asia, Australia and the Americas. Hookworm species have a worldwide distribution, mostly in areas with moist, warm climates where larvae can survive in the environment. ceylanicum may be zoonotic, as two haplotypes have been identified, one found only in humans thus far and the other found in humans, dogs, and cats. Humans are the principal host for both A. americanus does not appear to be infective via the oral or transmammary route. caninum-associated eosinophilic enteritis is believed to result following oral ingestion of larvae, not percutaneous infection. caninum infections may also be acquired by oral ingestion. duodenale may probably also occur by the oral and the transmammary route. These larvae are capable of re-activating and establishing patent, intestinal infections. duodenale larvae, following penetration of the host skin, can become dormant (hypobiosis in the intestine or muscle). Most adult worms are eliminated in 1 to 2 years, but the longevity may reach several years. Adult worms live in the lumen of the small intestine, typically the distal jejunum, where they attach to the intestinal wall with resultant blood loss by the host. The larvae reach the jejunum of the small intestine, where they reside and mature into adults.

They penetrate into the pulmonary alveoli, ascend the bronchial tree to the pharynx, and are swallowed.

On contact with the human host, typically bare feet, the larvae penetrate the skin and are carried through the blood vessels to the heart and then to the lungs. These infective larvae can survive 3 to 4 weeks in favorable environmental conditions. These released rhabditiform larvae grow in the feces and/or the soil, and after 5 to 10 days (and two molts) they become filariform (third-stage) larvae that are infective. Eggs are passed in the stool, and under favorable conditions (moisture, warmth, shade), larvae hatch in 1 to 2 days and become free-living in contaminated soil.
