Comparative studies on indirect hemagglutination test and enzyme linked immunosorbent assay for diagnosis of schistosomiasis

Prevalence of S. mansoni infection was higher than S. haematobium among population in the rural area of Sharqia Governorate. Incidence of infection and intensity of egg count were higher among EGAS 10-15 years than other ages. ELISA technique was more sensitive and specific than IHA technique, but reproducibility and ease of operation were the same in both techniques

Some factors affecting the development of ancylostoma duodenal eggs in-vitro

The objective of the present work was to study the effect of some chemical agents commonly used in household practice and for agricultural purposes as well as some physical agents viz. irradiation on the development, hatchability and survival of Ancylostoma eggs and larvae in cultures. The most effective agents were malathion, DDT, sodium chloride solution, ethyl alcohol and the detergent [savo]. Acetic acid was the least effective. On the other hand, irradiation effect on the development, hatchability and survival of eggs and larvae of the hookworm was almost negligible

Effect of some antibiotics and chemotherapeutics on Trypanosoma Lewisi infection in albino rats

Tartar emetic, suiphamethoxazole, amoxycillin and rifampicin were tested for their efficacy in the treatment of Trypanosoma lewisi infection in white rats. Tartar emetic and rifampicin are the most effective drugs for eradication of T. lewisi

Trials of some antibiotics and chemotherapeutics on experimental trichinosis

Four drugs were tested for their effect on the intestinal and/or the muscle phase of Trichinella spiral is in rats. Thiabendazole was the most effective during the intestinal phase. Mebendazole reduced the number of larvae. Rifampicin and bleomycin had a weak action on larval count. Histopathological findings confirmed the previously mentioned results. During the muscle phase, all drugs were found to be ineffective except bleomycin which showed a mild effect on larval viability

biological study on ova of enterobius vermicularis

The effect of some physical and chemical agents on the viability and hatchability of the eggs of pin-worms was studied. Sodium chloride solution proved very much effective. The detergent savo gave also good results in contrast to ethyl alcohol and acetic acid. Besides, 70 kilo volts X-ray for 1.5 minutes and, ultraviolet rays for 3 and 10 minutes gave good results

Assessment of some preservation and staining methods of encysted larvae of helminths

In hydatid cysts, the best results were obtained with specimens fixed in 10% formalin and stained with Zeihl-Neelsen. Trichinella cysts a high degree of perfection was obtained with specimen fixed in 10% formalin and stained with haematoxylin and eosin, or fixed in glycerol 4% saline and stained with .the former stain or with Delafield's stain. Equal degree of perfection was mostly obtained with the forementioned stains when fixed in Bouin's or Zenker's fixative

Bancroftian filariasis in young adult males from Nile Delta

The infection rate with filaria was highest among persons living in slum areas of small towns. The prevalence depends mainly on the residential and socio-economic rather than the occupational status. All known manifestations of filariasis were encountered except filarial fever elephantiasis of limbs. Eosinophilia was not pathognomonic

Some factors affecting the hatchability of schistosoma ova and miracidial activity

The effect of some factors on the hatchability of Schistosoma haematobium ova and the viability of miracidia were investigated. These included the longevity, salinity, pH, osmotic pressure, copper sulphate, sodium pentachlorophenate and immune serum. Results were statistically analysed and discussed

study of the rectal snip transparency and kato techniques in diagnosis of intestinal schistosomiasis

A comparative study of the rectal snip transparency and Kato techniques revealed that both methods are highly sensitive in the diagnosis of intestinal schistosomiasis. Nevertheless, it was concluded that any of them is not sufficient alone especially in cases intended to assess cure or activity of the disease

Hydatid infection in some animals in Egypt

Camels proved to be highly infected as compared to sheep. The I.H.A.T. showed that the immune response depends on the location, size, number and viability of cysts. Sheep were serologically positive, with no cysts, in lungs or liver perhaps may be located in other organs. R. norvegicus are recorded to harbour infection, probably E. multilocularis

Preservation and staining of ascaris lumbricoides ova

Four fixatives, seven stains and three mounting media were tried and evaluated. The best results were obtained with formolglycerine as fixative malachite green as a stain, and gum mixture as mounting medium

influence of host age on the survival and frequency of feeding of adults xenopsylla cheopis

It was noted that adult fleas survived longer when fed on baby mice at mild and high but not very high relative humidities. Similarly they required more blood meals when maintained on baby mice. The effect of relative humidity on the frequency of meals was stressed

Assessment of stool examination by various techniques

Direct smear, brine floatation and Stoll's modified techniques were used to assess their feasibility and for the detection of helminthic eggs. The best results were attained by the modified Stoll's technique, alone or combined with the brine floatation technique, although it is time consuming

contemporary survey on schistosomiasis in Zagazig Sharkia Governorate, Egypt

The results obtained denote that Schistosoma mansoni infection is on the increase. Its prevalence is approximating that of S. haematobium. Sex does not seem to contribute much to Schistosoma prevalence in this region, especially in the young age group. In virtue of this finding, schistosomiasis should not be considered as an occupational disease. Its prevalence depends rather on the extent of exposure to infected waters. This might explain why schistosomiasis is commoner in rural than in urban areas
