| arrested development in human hookworm infections: an adaptation to a seasonally unfavorable external environment. | contrary to general belief, larvae of ancylostoma duodenale do not always develop directly to adulthood upon invasion of man. in west bengal, india, arrested development appears to be a seasonal phenomenon which results in (i) reduction of egg output wasted in seeding an inhospitable environment and (ii) a marked increase in eggs entering the environment just before the monsoon begins. | 1973 | 17817813 |
| arrested development in ancylostoma duodenale: course of a self-induced infection in man. | the course of self-induced infection with about 100 ancylostoma duodenale larvae was followed by twice-weekly blood and stool examinations. after a small initial increase, no further change in eosinophil counts occurred until the 33rd week of infection when they began to increase sharply. seven weeks later, eggs were first observed in stools. thus, in this infection, the prepatent period was five times the expected. it is suggested that a strain of a.duodenale exists which either 1) has an inher ... | 1974 | 4451228 |

| the topographic distribution of necator americanus and ancylostoma duodenale in the human intestine. | during an investigation in dar es salaam, tanzania, 28 human intestinal tracts were systematically inspected on the presence of hookworms. in total, 643 hookworms (508 necator americanus and 135 ancylostoma duodenale) were isolated from 19 intestinal tracts. the localization of these hookworms was determined. n. americanus worms were concentrated in the duodenum and jejunum, whereas a. duodenale worms rather prefer the jejunum and proximal ileum. some preference of hookworms for the antimesenter ... | 1975 | 1179482 |
| biology of soil-transmitted helminths: the massive infection. | 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 regularly, however, ascaris disease is a form of malnutrition. trichuris trichiura causes diarrhea and dysentery and, at times, rectal prolapse. the hookworms, necator americanus and ancylostoma duode ... | 1975 | 1052507 |

| population biology of hookworms in children in rural west bengal. ii. acquisition and loss of hookworms. | from changes in hookworm egg counts in feces of children in gangetic west bengal we estimate that, on the average, each child lost about 11.1 female hookworms during the 1969 post-monsoon dry period and gained about 10.3 females during the subsequent premonsoon and monsoon seasons, resulting in a net loss of worms over the 22-month study period. however, the mean fecal egg count for each 1-year age group of children from 3-11 years suggests an average net gain of 2.7 female worms/year. from seas ... | 1978 | 727321 |
| population biology of hookworms in children in rural west bengal. i. general parasitological observations. | hookworm infection was studied over a 22-month period in 31-49% of a population of 1,803 1- to 10-year-old children in a rural area near calcutta where both necator americanus and ancylostoma duodenale were prevalent. half of the children were infected before age 5 and 90% were infected by age 9, when the mean egg count reached 2,000 eggs/g of feces. infection was significantly heavier and more prevalent among males than among females, and greater among muslims than among hindus. these differenc ... | 1978 | 727320 |
| human ancylostoma infections in nigeria. | an estimate of the proportion of infections with ancylostoma duodenale and necator americanus by the examination of larvae collected from the stools of 220 persons infected with hookworm was made. fifty-nine per cent of the infections were due to n. americanus only: a. duodenale always occurred in association with n. americanus. in 12% of the infections it is suggested that there were approximately three female a. duodenale to 95 female n. americanus. the highest numbers of a. duodenale in mixed ... | 1978 | 697443 |
