schistosomiasis as a worldwide problem: pathology. | low-grade schistosome infection is often well tolerated, except for the danger of ectopic lesions; the risk of life-threatening pathology increases with rising worm burdens. at present, quantitative stool or urine egg counts do not reliably measure individual infection intensity, especially in adult patients, and more precise methods are needed on which to base therapeutic decisions. timely schistosomicidal treatment will prevent or improve bilharzial lesions, often dramatically, but can not rev ... | 1975 | 1107577 |
hypersensitivity to parasite proteolytic enzyme in schistosomiasis. | a proteolytic enzyme which hydrolyses hemoglobin was obtained from the supernatant fraction of homogenized schistosoma mansoni. this enzyme elicited histaminic skin reactions in various animals, including man, which were infected with s. mansoni. it failed to induce reactions in monkeys harboring s. haematobium, s. japonicum, or s. intercalatum. in a preliminary field trial in the caribbean, the skin test proved to be somewhat less sensitive than the customarily used extract of adult worms in co ... | 1975 | 1111360 |

renographic studies in vesical schistosomiasis in children. | renal function in children infected with schistosoma haematobium and in uninfected controls has been studied with the i131 hippuran renogram. the results suggest that renographic abnormalities which persist after a water-load are more common in infected children who have heavy egg-output in their urine, and abnormal pyelograms. specific chemotherapy restored the renogram to normal within 3 weeks in several cases. it is suggested that the renogram is useful for the assessment and followup of pati ... | 1975 | 1119668 |
studies on schistosomiasis in somalia. | a survey was made on the prevalence and intensity of schistosomiasis in 14 localities in 4 areas in somalia has revealed the presence of urinary bilharziasis among the inhabitants of all these localities, this being much higher in the two areas where water development has been accomplished. the mean prevalence of infection was found to be 27.2% and 58.1% in the two areas where water development has only been planned, while it was 58.7% and 75.6% in the two areas where the extension of irrigation ... | 1975 | 1119669 |
the relation of worm burden to passage of schistosoma haematobium eggs in the urine of infected patients. | patients scheduled for cystectomy for bladder carcinoma or exstrophy of the bladder were studied. the number of eggs per day passed in the urine preoperatively was compared with the number of worms recovered from the cystectomy specimen by dissection. a mean of 203 embryonated schistosoma haematobium eggs per day per worm pair were recovered from the urine of active, untreated cases. the relation between the number of s. haematobium females recovered and the number of living eggs passed in the u ... | 1975 | 1119670 |
suppression of delayed hypersensitivity in schistosome-infected patients by niridazole. | niridazole, an anti-parasitic drug, suppresses manifestations of delayed hypersensitivity and retards allograft rejection in laboratory animals. we investigated the immunosuppressive effects of the standard antihelminthic regimen of niridazole (25 mg/kg/day for seven days) in five patients with schistosomiasis. although 15-minute skin reactions to schistosomal antigens remained unchanged, niridazole reduced or ablated positive 48-hour skin reactions to tuberculin (ppd), mumps and schistosome ant ... | 1975 | 1124104 |

seasonal population densities of snails transmitting urinary and intestinal schistosomiasis in lusaka, zambia. | the two molluscan intermediate hosts of s. haematobium schistosomiasis: bulinus africanus and bulinus globosus, were found most commonly in habitats that retained water for a substantial part of the year rather than in temporary rain-filled pools. biomphalaria pfeifferi which transmits s. mansoni were found principally in streams and impoundments like dams but scarce in rivers. in a permanent habitat, the peak density of snails was between the warm, dry months of august and september while in a ... | 1975 | 1169833 |
solitary epididymal schistosomiasis. | a 54-year-old canadian presented with a 1-month history of painless swelling in the right testis. the diagnosis was thought to be a sperm granuloma, a leiomyoma, or an adenomatoid tumour of the epididymis; histologic examination, however, revealed evidence of schistosomiasis, probably due to schistosoma haematobium. solitary schistosomiasis of the epididymis has been reported previously in only two cases. epididymal schistosomiasis has never been diagnosed preoperatively because it is so rare, b ... | 1975 | 1175114 |

a quantitative post mortem analysis of urinary schistosomiasis in egypt. ii. evolution and epidemiology. | further analysis of the data obtained from 190 unselected autopsies at the university of cairo (faculty of medicine) hospitals reinforces our conclusion that a high prevalence of urinary schistosomiasis leads to infection intensity causing severe uropathy and mortality, both directly and by way of complications and sequelae. based on histological study, two stages of urinary schistosomiasis must be considered in epidemiological work: "active disease", characterized by significant egg excretion; ... | 1975 | 1190367 |
effect of the aswan high dam on prevalence of schistosomiasis in egypt. | an increase in the prevalence of schistomiasis in egypt, as a result of the aswan high dam, has for long time been predicted because of reclamation of land and conversion of annual flooding (basin irrigation) into perennial irrigation in upper egypt. two aspects, neglected in the predictions, have been investigated in the present study, and these are: the ecological changes, relevant to the transmission of the disease, in the nile itself, and those in irrigation canals and drains in areas which ... | 1975 | 1216315 |

relationship between pure schistosoma haematobium infection in upper egypt and irrigation systems. part 1: methods of study. | four villages in assiut governorate were studied. they were matched for availability and time of introduction of medical services, the size of population and the socioeconomic status. one village had a basin system of irrigation. the other three villages had perennial irrigation introduced at different dates. a sketch map of each village was made showing the location of every house and the irrigation channels. total coverage was intended in gezirat el-maabda (with basin irrigation) and nazza kar ... | 1975 | 1230346 |
relationship between pure schistosoma haematobium infection in upper egypt and irrigation systems. part ii: host characteristics. the general prevalence of schistosoma haematobium, age and sex distribution. | the epidemiology of bilharziasis was studied in four villages in assiut governorate. these villages were almost similar with respect to their socioeconomic conditions, modes of living, availability and date of introduction of medical services. the first village, gezirat el-maabda, has a basin system of irrigation. the other three villages had shifted to the perennial system of irrigation for three years in nazza karrar, 26 years in el-ghorayeb and 95 years in garf sarhan and were similar with re ... | 1975 | 1230347 |
relationship between pure schistosoma haematobium infection in upper egypt and irrigation systems. part iii: host characteristics. the prevalence of s. haematobium in relation to religon, occupation, and habits. | study of the effect of religion on the prevalence of s. haematobium infection revealed that ablution and other muslims rituals do not represent an important factor in the prevalence of s. haematobium. data concerning the effect of education on the prevalence of s. haematobium show that it has no significant role when similar age groups were compared. farming was shown to be the occupation of leading importance with rest to exposure to s. haematobium infection, as farmers and farm labourer const ... | 1975 | 1230348 |

studies on schistosoma bovis in ethiopia. | schistosoma bovis occurs in at least seven of the 14 rovinces of ethiopia. results of faecal and snail surveys in three foci are reported. adwa. one collection showed that nine out of 26 bulinids were infected with s. bovis. the snail host was a tetraploid form of bulinus (n = 36). the examination of 200 specimens of cattle faces revealed no s. bovis eggs, which was attributed to poor technique or light infection. gewani. the snail host was bulinus abyssinicus, which was also infected with s. ha ... | 1975 | 808181 |
experimental schistosomiasis haematobia in bushbaby (galago crassicaudatus), patas (erythrocebus patas), and grivet (cercopithecus aethiops). | the bushbaby (galago crassicaudatus), patas (erythrocebus patas), and grivet (cercopithecus aethiops) have been evaluated as hosts in experimental schistosomiasis haematobia. individual hosts demonstrated considerable variation in host-parasite relationships. e. patas is suggested as a host for continuing investigations in schistosoma haematobium infections, based upon its moderate susceptibility to infection and a moderate potential for pathological involvement of the urogenital system. | 1975 | 808620 |
immunodiagnosis of human schistosomiasis using different immunoprecipitation techniques. | one hundred sera of individuals infected with schistosoma mansoni and/or s. haematobium were examined for the presence of specific anti schistosoma antibodies by means of different immunoprecipitation techniques: immunoelectrophoresis, immunodiffusion, immunoelectroosmophoresis (on two different supports), and electroimmunodiffusion. the immunoelectroosmophoresis proved to be superior to the other immunoprecipitation techniques, its main advantages being sensitivity, rapidity, and economic use o ... | 1975 | 810988 |
treatment of chronic enteric fever with amoxicillin. | twelve patients with proven salmonella typhi or salmonella paratyphi a bacteriuria and recurrent bacteremia associated with schistosomiasis were treated for four weeks with amoxicillin (250 mg four times daily). seven of the 12 patients were seriously ill and febrile before treatment. they showed a dramatic response, and, within three to six days of initiation of amoxicillin therapy, they were afebrile and much improved clinically. amoxicillin was rapidly and highly concentrated in the urine of ... | 1975 | 811715 |
ascorbic acid effect on intestinal iron absorption in different types of anaemias. | the study deals with investigations on anaemia due to iron or protein calorie deficiency and that associating acute glomerulonephritis, nephrosis and schistosoma haematobium. the rate of intestinal iron absorption using an oral dose of ferrous sulphate equivalent to 4 mg clemental iron/kg body weight was studied. the supplementing action of ascorbic acid in iron absorption in these cases was also investigated. the rate of intestinal iron absorption was enhanced in pure iron deficiency anaemia, a ... | 1975 | 816695 |

field studies of a rapid, accurate means of quantifying schistosoma haematobium eggs in urine samples. | a new means of quantifying schistosome eggs has been adapted from the laboratory to the field. urine from 510 individuals in areas of kenya with a high prevalence of schistosomiasis haematobia was injected in aliquots of 10, 5 and 1 ml on to transparent nuclepore filters, 13 mm in diameter. the filters were placed face down on glass slides and were read without staining at x40 magnification. the method has been shown to be accurate, sensitive, and reproducible, and also extremely rapid. | 1976 | 1088097 |
4-isothiocyanato-4'-nitrodiphenylamine (c 9333-go/cgp 4540), an anthelminthic with an unusual spectrum of activity against intestinal nematodes, filariae and schistosomes. | 4-isothiocyanato-4'-nitrodiphenylamine was found to possess activity against intestinal nematodes in mice, against schistosomes in various hosts including primates and against two filarial species in the mongolian jird. upon administration in a single oral dose it is equally effective against s. haematobium, s. mansoni and s. japonicum. | 1976 | 817928 |
proliferative epithelial lesions of the urinary bladder in cynomolgus monkeys (macaca fascicularis) infected with schistosoma intercalatum. | five cynomolgus monkeys (macaca fascicularis) were infected with schistosoma intercalatum, a helminth that is morphologically similar to schistosoma haematobium. infections were readily established and remained active until the monkeys were sacrificed 21 to 84 weeks after exposure. although the schistosomes were located predominantly in mesenteric and hepatic portal venules, schistosome eggs were found in the bladders of 3 monkeys. nodules of atypical epithelial cells interpreted as superficiall ... | 1976 | 819136 |
experimental biharzial bladder cancer: tryptophan metabolism in nonhuman primates experimentally infected with schistosoma haematobium. | a nonhuman primate species infected with schistosoma haematobium provided a model system for controlled studies on biharzial bladder cancer. urinary excretion of tryptophan metabolites by capuchin monkeys (cebus apella) was similar to that of humans when expressed per g creatinine. liver tryptophan oxygenase activity of the capuchin monkeys was comparable to that of humans. excretion of 3-hydroxykynurenine and 3-hydroxyanthranilic acid was elevated above control levels in capuchin monkeys infect ... | 1976 | 815556 |

scanning electron microscopy of the integumental surfaces of schistosoma haematobium. | the integumental surfaces of critical point dried s. haematobium were studied by scanning electron microscopy at 34 to 8,000 magnifications. there are marked differences between the surface structures of male and female as well as from one part of the same parasite to another. the surface of the male schistosome is moderately rough while that of the female is relatively smooth. sem reveals certain basic features such as spines in the oral sucker and the acetabulum of both sexes which may facilit ... | 1976 | 1255386 |
cryptococcal granuloma (toruloma) of the central nervous system in a patient with schistosomiasis. | a case of cryptococcal granuloma of the brain and lung is described in a nigerian woman who also had schistosoma haematobium infection. | 1976 | 1259076 |
a comparative study of the death of schistosomula of schistosoma haematobium and schistosoma mansoni in the skin of mice and hamsters. | this study shows that some cercariae of s. haematobium and s. mansoni die during penetration of mouse or hamster skin. approximately 30-38% of cercariae of both species die in mouse skin and 14-16% die in hamster skin. the greater number of cercariae which die in the skin of mice seems to account for the higher yield of adult worms recovered in hamsters. adult worm recoveries from animals infected with s. haematobium were, however, only about half the worm recoveries from hosts infected with s. ... | 1976 | 1262692 |
intermediate host antigens associated with the cercariae of schistosoma haematobium. | bulinus (physopsis) africanus antigens were shown to be associated with the cercarial glycocalyx of schistosoma haematobium using immunofluorescence and the cercarienhüllen reaktion. it is proposed that this snail antigen may sensitise the definitive host and that resistance to further invasion by cercariae could be induced in this manner. | 1976 | 1262693 |
the timing of reproductive cell development and movement in schistosoma mansoni, s. japonicum, and s. haematobium, using techniques of autoradiography and transplantation. | tritiated thymidine was incorporated into gonial and vitelline cells of male and female schistosoma mansoni, s. japonicum, and s. haematobium after 2 hr of incubation. spermatogonial cells developed into labeled mature sperm after 6 days of transplantation in all species. insemination of females was detected on the same day indicating copulation is frequent. oogonia labeled in the initial incubation matured into primary oocytes after 7 days of transplantation for s. mansoni and s. haematobium an ... | 1976 | 1263031 |
