A 54-year-old male was admitted because of having suffered from progressive watery diarrhea for 12 days. He had no history of diabetes mellitus, hypertension, heart disease, organ transplantation, or malignancy. After admission, he still complained of diarrhea despite medical treatment. The
Ancylostoma (A.) ceylanicum, one of the most common species of hookworms infecting dogs and cats, also causes patent infections in humans and is now considered to be the second most common hookworm species infecting populations in southeast Asia. A Japanese patient who returned from a visit to
During 1983, a multinational military intervention took place on Grenada. After deployment, troops from several U.S. Army units noted signs and symptoms consistent with soil-transmitted helminthic infection. Of 684 soldiers screened five to seven weeks post-deployment, over 20% reported abdominal
A new compound, 4-isothiocyanato-4'-nitrodiphenylamine (C.9333-Go/CGP 4540), was tried in 39 hospitalized patients with hookworm infection, using several treatment schedules. At effective dose schedules (125 mg X 3 given 4-hourly; 250 mg X 3, 8-hourly; 1,000 mg X 3, 12-hourly), the egg reduction was
A model of human hookworm infection has been defined with a strain of Ancylostoma ceylanicum that is known to be infective for humans. In the first experiment, dogs were infected with between 150 and 12,150 filariform larvae and followed up for six weeks. A direct relation was found between the size
An imported case of rectal hookworm infection was diagnosed by stool examination and recovery of adult worms from the rectal mucosa by sigmoidoscopy. The chief complaints of a patient were diarrhea, abdominal pain and weight loss for about 1 month after returning from his travel abroad to the

Countries in the Southeast Asia region have a high prevalence of soil-transmitted helminth, such as roundworm, whipworm, and hookworms [Ancylostoma duodenale, Necator americanus, Ancylostoma ceylanicum]. Recent molecular-based surveys have revealed that A. ceylanicum, a zoonotic hookworm,
Soil-transmitted helminth infections when light-to-moderate usually are well tolerated, but heavy-to massive infections invariably cause disease. A massive infection with Ascaris lumbricoides may cause intestinal obstruction, liver abscess, or some other condition requiring surgical treatment; more
Soil-transmitted helminth (STH) infections are common. Indeed, more than 1 billion people are affected, mainly in the developing world where poverty prevails and hygiene behavior, water supply, and sanitation are often deficient. Ascaris lumbricoides, Trichuris trichiura, and the two hookworm
Tropical medicine as a specialty began during colonialization of the tropics. From the outset, controversy focused on scientific research (tropical medicine) vs. public health (tropical health). The former became associated with parasitology to the relative exclusion of microbiology. Remarkable
BACKGROUND
Qualitative evidence suggests that inadequate water, sanitation and hygiene (WASH) may affect diarrheal and helminthic infection in women disproportionately. We systematically searched PubMed in June 2014 (updated 2016) and the WHO website, for relevant articles.

In this preliminary study, a total of 8006 schoolchildren (aged 9-19 years) from 77 elementary schools was screened for infection with Ascaris lumbriocoides, Trichuris trichiura and hookworms using the Kato-Kata method. A. lumbriocoides was commonly encountered (35.4%) followed by the hookworms
Trichuriasis may be asymptomatic or, in heavy infection, lead to profuse, bloody diarrhea and rectal prolapse. Diagnosis is made by finding the distinctive barrel shaped eggs in the stool or in the heavily infested patient, by anoscopy and identification of worms attached to reddened and ulcerated
From a study of strongyloides infections in man and animals in this region, it has been determined, in confirmation of the view of Grassi, Calmette, and others, that they are not causative factors in the production of diarrhea. The mother worm, however, burrows into the mucosa and deposits her ova
