| 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 |
| [coprologic survey in bilharzia infected children of the adzope region (ivory coast)]. | during a stool examination survey on 174 bilharzia attained children living in a rural area of ivory coast, 93% were found to have intestinal parasites mainly entamoeba coli, necator americanus and ascaris lumbricoides. the prevalence of the cysts of entamoeba histolytica (4,7%) is lower than the one found in france (7%). concerning the other intestinal parasites, their respective occurrence have been compared with those noted in other regions of ivory coast and of africa. | 1975 | 170007 |
| mechanism of skin penetration by ancylostoma tubaeforme larvae. | skin penetration by infective ancylostoma tubaeforme larvae has been investigated cinematographically and using in vitro techniques. the dermal tissue appears to cause little hinderance to larval migration but complete penetration through the skin from the dermal direction did not occur, although total penetration from the epidermal surface was frequently accomplished. no evidence could be found for enzymic secretions emanating from the worms under conditions that gave positive results from neca ... | 1975 | 235107 |
| evaluation of the skin test for hookworm as an epidemiological tool. | the usefulness of a skin test with larval necator americanus antigen for assessment of hookworm prevalence was evaluated in an endemic area of costa rica. in comparison with standard coprologic techniques employed to survey the population, the skin test detected 83% of infections, showing a fairly satisfactory sensitivity. the overall specificity of the test was 50%, i.e., random. no correlation was found between skin reactivity and hookworm burden. the sensitivity of the test increased moderate ... | 1975 | 1119666 |

| 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 |
| variation in delayed hypersensitivity in onchocerciasis. | soluble antigen preparations were made from onchocerca volvulus adults recovered from subcutaneous nodules, and from necator americanus third-stage larvae. intradermal skin tests were carried out on a total of 100 individuals clinically classified as having either the generalized form of onchocerciasis (86 cases, or the localized sowda form (14 cases). 91 of the people studied produced immediate reactions to the onchocercal antigen, but only those with sowda showed delayed reactions, though one ... | 1978 | 705843 |
| 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 |
| 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 |
| [epidemiological study on the hookworm infections in korea] | this study was undertaken to evaluate the present status of hookworm infections in korea from october 1976 through september 1978. the stool specimens of 5,632 persons(male 3,689: female 1,943) collected from primary and middle schools, foundling asylums, and the general populations of various parts in korea were examined the methods employed were brine floatation technique for the prevalence rate of hookworm infections, kato's cellophane thick smear technique for the other helminthic infections ... | 1978 | 12902770 |
| non-specific potentiation of ige by parasitic infections in man. | infection with the helminthic parasites ascaris lumbricoides and/or necator americanus (hookworm) induces the production in man of high levels of serum ige. the specificity of this ige antibody when measured by rast to a wide range of allergens was restricted in general to the helminthic antigens. absorption of the sera with immunosorbents produced by coupling extracts of a. lumbricoides to cnbr activated sepharose 4b established that ascaris antigen specific ige antibodies contributed a minor f ... | 1979 | 370030 |

| homology between roundworm (ascaris) and hookworm (n. americanus) antigens detected by human ige antibodies. | utilizing the techniques of radioallergosorbent test (rast), inhibition of rast and isoelectric focusing on polyacrylamide gels, antigenic cross-reactivity has been shown between extracts of ascaris lumbricoides. ascaris suum and necator americanus (hookworm). antigenic homology is extensive between the two ascaris preparations. the antigens common to hookworm and ascaris, while representing a minor component of ascaris body fluid, are nonetheless potent stimulators of ige antibody production in ... | 1980 | 7458774 |
| anthelmintic effect of amidental (bay d 8815) against ancylostoma duodenale infection. | a new anthelmintic, amidantel(bay d 8815), an acetylated p-amino-phenyl-acetamidine was tried in 140 patients with ancylostoma duodenale and other helminth infections. in the first trial, each 16 cases in 64 patients with a. duodenale were treated with 3.0, 6.0 and 9.0 or 10.0 mg/kg body weight of amidantel including placebo control. another 76 patients infected with hookworms and other helminths were treated with 5.0, 6.0 and 8.0 mg/kg body weight of amidantel in the second trial. in order to a ... | 1980 | 12902739 |
| the infectivity of ingested adult hookworms. | fourth-stage larvae and adults of ancylostoma ceylanicum (dog strain) produced patent infections, with fertile ova, in hamsters to which they had been given in a drench. similarly, 36-day-old (immature adult) necator americanus given in a drench to hamsters also produced patent infections with fertile ova. the epidemiological significance of these experiments is discussed. | 1981 | 7198834 |
| [epidemiological survey and sanitary problems in a village in east central madagascar]. | an evaluation of health problems is done in a village in eastern madagascar, where takes place a development programme. 217 inhabitants go through physical examination and lab tests are performed (blood smear - thick drop. emmel test. stools examination for parasites and enteroviruses). the epidemiologic investigation reveals the prevalences of malaria (39,4 p. 100) intestinal schistosomiasis (59,9 p. 100) ascaridiasis (61,3 p. 100) hookworm (29,9 p. 100) trichuriasis (19,8 p. 100) and sickle ce ... | 1981 | 7200761 |
