Disseminated hymenolepis nana in bood of a filarial patient

A female patient aged 13 years, from Kafr-Osman, Giza governorate suffering from microfilaraemia showed disseminated Hymenolepis nana in her blood. The effect of filariasis and the immunosuppression of a corticosteroid treatment taken for an attack of cutaneous allergy are a possible cause for dissemination of a heavy intestinal H. nana adults. This is an important indication to exclude parasitic infestations before any immuno-suppressive treatment to limit the phenomenon of aberrant metastasising their larval forms

Histochemical observations on the effect of quaranfil virus on the salivary glands of argas [persicargas] arboreus [ixodoidea: argasidae]

Stained salivary gland sections of uninfected and Quaranfil virus-infected female Argas [P.] arboreus were compared. Hematoxylin and eosin and the histochemical stains for glycogen [PAS], basic proteins [Hg-BPB] and lipids [Sudan-black S] were employed. The effect of Quaranfil virus infection on postfeeding histochemical changes in the salivary glands were recorded. Basic protein content of A, Ba, Bb, and Bc cells was higher in most alveoli of infected salivary glands than in uninfected ones. Postfeeding time-related changes in the histochemical staining reaction of type of B-alveoli are described in detail

Quaranfil virus in infected argas [persicargas] arboreus salivary glands

The possible differences in concentrations of DNA, RNA and other specific nucleic acids of Quaranfil [QRF] virus infected A. arboreus salivary glands, and those of uninfected ticks was tested histochemically. Also localisation of specific virus protein antigen in QRF virus infected glands was made by the indirect immunoflourescence and immunoperoxidase techniques

Preliminary study on biomphalaria Alexandrina chromosomes

Laboratory colony of Biomphalaria alexandrina snails showed 18 pairs of chromosomes in the mitotic cell divisions. Haploid number is 18 ie n = 18. All chromosomes are nearly of equal size and all are metacentric. Diploid spreads showed increased or decreased numbers is 37 or 35. Further study is recommended

rodent reservoir hosts and intermediate hosts of hymenolepis diminuta [Rudoiphi, 1819] in Egypt

Different species of rodents were monthly collected from Abu-Rawash village during the years 1978-1979. Their ectoparasitic infestation with fleas was studied.The incidence of infection as well as the seasonal rate of infection with H. diminuta worm among the different species were determined. Experimental infection of X. cheopis larvae with H. diminuta was tried

Some abnormalities of hymenolepis diminuta [Rudolphi, 1819]

Different abnormalities of mature and gravid segments of Hymenolepis diminuta from the small intestines of Rattus rattus and abnormally developed cysticercoid larvae in Tribolium confusum are given

Acute appendicitis as a complication of helminthic infection among some Egyptian patients

One hundred sixty cases of acute appendicitis admitted to University Hospital, Zahraa and Operated upon were studied for helminthic infection. In eleven cases different helminthes were detected. Regular laboratory parasitological examination of school pupils is recommended to avoid complications and to minimise mortality and morbidity of surgical intervension
