quantification of infection with schistosoma haematobium in relation to epidemiology and selective population chemotherapy. i. minimal number of daily egg counts in urine necessary to establish intensity of infection.	the intensity of infection with schistosoma haematobium (worm burden) can be approximated by quantifying the number of parasite eggs excreted in the urine. a new method of egg counting has been developed in which urine samples are passed through transparent nuclepore filters (nuclepore corp., pleasanton, calif.). the method requires no staining, is rapid, and can be performed in the field. it has previously been reported, however, that there is a significant daily fluctuation in output of eggs i ...	1978	570210
[inhibition of ea and eac rosette formation by sera of patients with vesical schistosomiasis].	circulating immune complexes were investigated by the e.a. and e.a.c. rosette inhibition test in sera samples from patients infested by schistosoma haematobium. about 60% of the patients demonstrated significantly higher inhibition values than controls. the material inhibiting e.a.c. rosette formation was precipitated by 3.5% polyethilene glycol, thus excluding the role of c3 fragments and suggesting that inhibition was due to immune complexes.	1978	757619

cystoscopic picture of schistosoma haematobium in egyptian children correlated to intensity of infection and morbidity.	cystoscopy was done on 45 children, 5--12 yr old, infected with schistosoma haematobium. on the basis of urinary egg output, the children were classifed as having mild, moderate, or heavy infection and the cystoscopic picture was correlated with their egg output and with their signs and symptoms. lesions reported, in descending order of frequency, were: hyperemia, sandy patches, tubercles, ulcers, nodules, and polyps. multiple schistosomal lesions were present in some patients and the frequency ...	1978	686243
on factors possibly restricting the distribution of schistosoma intercalatum fisher, 1934.	two hypotheses have been postulated explaining the limited distribution of schistosoma intercalatum. the first hypothesis is correlated with physical factors and behaviour of cercariae. histochemical and ultrastructural studies have shown that in response to increased temperature change the cercariae of s. intercalatum form aggregates, unlike other schistosome cercariae of man, which are non-infective to the definitive host. the aggregates are formed by the release of the adhesive post-acetabula ...	1978	695826
hycanthone therapy in selected patients with s. mansoni and s. haematobium infections in the sudan.	the results of a clinical trial of hycanthone in 601 selected sudanese patients with s. mansoni and s. haematobium infections are reported. hycanthone was given as a single intramuscular injection at a dose of 3.0 mg per kilogramme body weight. the commonest side effects were nausea and vomiting which occurred in 35 per cent and 32 per cent respectively. no incidence of acute hepatic damage and no deaths were encountered. about one third of patients reported for follow-up. cure rate for s. manso ...	1978	702619

size and shape analysis of schistomsome egg-counts in egyptian autopsy data.	we study egg-counts from a series of egyptian autopsy cases with active schistosomiasis at death (kamel, cheever, elwi, mosimann and danner 1977). the data are unique, and enable us to study the proportional distribution of eggs among various organs in relation to infection intensity for two species of schistosome worms. we develop a model for the distribution of eggs in three organs of the mesenteric circulation. under a lognormal distribution assumption, several exact statistical procedures ar ...	1978	719118
the influence of physical factors on the behaviour and infectivity of miracidia of schistosoma mansoni and s. haematobium. iii. effect of contact time and dispersion in static and flowing waters.	the scanning and infective capacity of schistosoma mansoni and s. haematobium miracidia were tested under limited exposure times in small volumes of water, and under increasing mutual dispersion in vessels of different sizes also over increasing horizontal distances, and under different flow rates of water. it was found that the miracidia of both species retained their infective capacity for up to 1 hour in the presence of susceptible snails. the infection rates decreased with decreasing miracid ...	1978	722043
glomerular lesions in patients with schistosoma haematobium infection.	in order to investigate the prevalence and type of glomerular lesions in patients with overt schistosoma haematobium (s h) infection, renal biopsies obtained from 13 patients were studied by light microscopy (in 13), ultra-structural (in 9) and immunofluorescence (in 11) techniques. renal function was normal in all patients, only two had mild proteinuria. glomerular deposits were absent in four patients. electron microscopy showed in four cases an increase of the mesangial matrix with subendothe ...	1978	726031
epidemiology of poly-parasitism. iv. combined effects on the state of health.	the assessment of morbidity caused by chronic parasitic infections in the populations of endemic areas has remained difficult and controversial. contributing to this predicament is the frequent occurrence of multiple infections with agents that can cause a wide range of clinical manifestations, from the frequent symptomless carrier state to overt disease with more or less specific clinical manifestations. in the interpretation of the complex morbidity patterns found in rural populations of tropi ...	1978	726041
serum immunoglobulin concentrations in human s. mansoni and s. haematobium infections in the sudan, with special reference to the effect of chemotherapy.	the serum immunoglobulin concentrations of igg, iga and igm were studied in 111 selected sudanese patients with s. mansoni infections and 48 with s. haematobium infections before and 6 weeks after successful treatment with hycanthone; 52 local individuals were studied as controls. both igg and igm were found to be significantly raised in s. mansoni patients compared with controls, while only igg was significantly raised in patients with s. haematobium infection. s. mansoni patients with the hepa ...	1978	726042
efficacy of medical treatment of schistosomal obstructive uropathy as determined by 131i-hippuran renography.	ten male patients with obstructive uropathy secondary to schistosoma haematobium and with associated bacteriuria were evaluated with serial urograms, renograms and renal function tests (endogenous creatinine clearance, maximal urinary concentration and total hydrogen ion excretion) before and after medical treatment. the mean duration of follow-up was 4.2 months. significant improvement was observed in the renograms and the renal function tests while the degree of obstructive uropathy as determi ...	1978	734719
quantification of infection with schistosoma haematobium in relation to epidemiology and selective population chemotherapy. ii. mass treatment with a single oral dose of metrifonate.	determination of the efficacy of mass treatment of schistosomiasis is usually based on the rate of cure. however, schistosomes do not multiply in the human host, disease tends to cluster in the small proportion of individuals with heavy infections, and reinfection continually occurs in endemic areas. thus drastic reduction in worm burdens can be a reasonable goal for mass treatment campaigns. the standard dose and regimen of metrifonate for the treatment of schistosomiasis haematobia is 7.5 mg/k ...	1978	739160

metrifonate trial in the treatment of various presentations of schistosoma haematobium and s. mansoni infections in the sudan.	the effect of metrifonate (bilarcil bayer) on schistosoma haematobium and s. mansoni infections was studied in 174 patients near khartoum. a high cure rate was obtained in s. haematobium infections, but anthelmintic efficacy was minimal in patients passing s. mansoni eggs in their stools. there was, however, a marked reduction of egg output in patients passing s. mansoni eggs in urine. this suggests that the site of infection in man, rather than the species of parasite, renders the parasite more ...	1978	352282
oxamniquine in the treatment of various schistosome infections in south africa.	trials of a new schistosomicide oxamniquine (vansil) were carried out in the lowveld of the eastern transvaal. after initial dose-finding trials, the safety and efficacy of oxamniquine against schistosoma mansoni at an oral dose of 15 mg/kg twice a day for 2 days (total dose 60 mg/kg), were confirmed. no detectable effect was noted against s. haematobium or s. mattheei.	1978	354047
bacteriuria in urinary schistosomiasis in egypt a prevalence survey.	an epidemiologic survey to assess the prevalence of bacteriuria in urinary schistosomiasis was carried out in a region endemic for urinary schistosomiasis in egypt. twenty of 390 (5.1%) school boys aged 5--16 years were bacteriuric. this prevalence rate is more than 10 times greater than that found in comparable surveys in areas non-endemic for urinary schistosomiasis. in this endemic population bacteriuria was found in 6.5% of active egg excreters and 2.3% of non-egg excreters.	1978	362956
metrifonate. summary of toxicological and pharmacological information available.	the organophosphorus compound 0,0-dimethyl-(1-hydroxy-2,2,2-trichloroethyl)-phosphonate was introduced as an insecticide, trichlorfon, in 1952 (lorenz et al., 1955) and as a drug, metrifonate, in the treatment of schistosomiasis in 1960 (lebrun and cerf, 1960). this organophosphorus compound is unique in that it has been claimed not to be a direct acting cholinesterase inhibitor but being transformed nonenzymatically into an active component dichlorvos, 2, 2-dichlorovinyl dimethyl phosphate (ddv ...	1978	363095

distribution of egg deposits and gross lesions in nonhuman primates infected with schistosoma haematobium (iran).	widespread tissue egg deposits and gross lesions were recorded in 15 species of primates subsequent to schistosoma haematobium (iran) infections of variable intensity and duration. considerable extra-intestinal involvement as well as pathology in different parts of the urogenital system were observed. transitional cell carcinoma of the urinary bladder was recorded for cebus apella.	1979	116002
immunobiology of schistosomiasis.	although malaria and hookworm disease appear to be on the decline, another dreaded parasitic disease-schistosomiasis-is on the increase. presently, the number of infected individuals with schistosomes is estimated to be 250 million, and even though only a small proportion of them become sick and die, schistosomiasis remains a medical problem of great significance. the high incidence of infection of man with schistosoma mansoni, schistosoma japonicum or schistosoma haematobium, as well as the chr ...	1979	118264

haematobium schistosomiasis in the squirrel monkey (saimiri sciureus).	the squirrel monkey (saimiri sciureus) accommodates schistosoma haematobium moderately well. adults occur in the major viscera but the extent of tissue egg deposits and associated pathology is variable. pathologic involvement of the urogenital system occurs in a large proportion of hosts exposed to moderate to heavy infections, and bladder pathology is indicative of conditions associated with bladder carcinoma.	1979	120625
distribution of blood groups and secretor status in schistosomiasis.	urine and stool specimens from 425 school children in swaziland were examined for evidence of schistosoma mansoni or schistosoma haematobium infection. concurrently, saliva collections were analysed for abh secretory ability and blood samples were typed for abo, rh and lewis groups. among individuals infected with s. mansoni, the frequency of blood group b was significantly increased (p < 0.001), and there was a greater prevalence of positive secretor status (p < 0.05). in contrast, the presence ...	1979	121770
preliminary report on long term cure of schistosomiasis using metrifonate (bilarcil/dipterex)--a new antischistosomal drug.	twenty patients aged between 7 and 19 years with confirmed vesical schistosomiasis due to schistosoma haematobium were treated with metrifonate (dipterex, bilarcil) orally on a single dose of 7.5 mg/kg body weight repeated at fortnightly intervals until egg excretion ceased. this was achieved with a maximum of three doses. no symptoms of toxicity or significant side effects were observed. four patients remained symptom free of the infection for up to three years after the initial treatment. thes ...	1979	122130
changing pattern of schistosomiasis in egypt 1935--79.	a village in the nile surveyed for schistosomiasis by j. a. scott in 1935 was surveyed again in 1979. the same number of people as in the 1935 survey were randomly selected for investigation by the same parasitological techniques as those used by scott. the prevalence of schistosoma mansoni infection had increased from 3.2% to 73%, whereas s. haematobium infection, which had been very common in 1935 (74%), had almost disappeared (2.2%). in the local district hospital since 1972 the percentage of ...	1979	89343

combination of a viability test and a quantification method for schistosoma haematobium eggs (filtration--trypan blue-staining-technique).	the efficiency of the polycarbamate membrane filtration technique for detecting schistosoma haematobium eggs in urine has been increased by using a pore size of 14 micrometers diameter and the suction of a water jet pump. the technique permits filtration of several 1000 ml of urine in one test. eggs concentrations of 1 egg in more than 1000 ml of urine were detected. viability was assess after filtration by staining with trypan blue. preliminary data of 118 schistosoma haematobium-positive urine ...	1979	94193

[female genital bilharziasis. 1 case].	in a swiss woman who had travelled in africa ovarian and tubal bilharziasis (schistosoma haematobium) was found by chance during laparotomy. in both sexes genital bilharziasis is nearly always caused by sch. haematobium and is a complication of bilharziasis of the bladder and intestine. genital bilharziasis in woman is found principally in the cervix and in the vagina, less commonly on the vulva and in the fallopian tubes and ovaries, and rarely in the body of the uterus.	1979	424717
the significance of proteinuria and haematuria in schistosoma haematobium infection.	the intensity and prevalence of proteinuria and haematuria were studied with urinanalysis reagent strips in a gambian community in which the intensity of infection with schistosoma haematobium was high. the level of proteinuria present was shown to be related to the intensity of infection. follow-up for 12 months showed that infected subjects with heavy proteinuria had a good prognosis. these findings suggest that the urinary protein in such subjects is likely to originate from lesions in the bl ...	1979	442186
granuloma size in the liver of mice with schistosoma haematobium infection and schistosoma mansoni challenge.	swiss albino mice have been infected with s. haematobium and challenged with s. mansoni. s. haematobium infection in the mouse runs a course more or less parallel to that of s. mansoni infection. granuloma has reached a maximal size at 135 days post infection and has regressed thereafter. suppression of s. mansoni granuloma was observed in mice previously infected with s. haematobium. this manifests the presence of cross immunization.	1979	442201
