Coriandrum sativum has been used in Iranian traditional medicine as an anti-inflammatory, antioxidant, antibacterial, and antifungal agent. The purpose of this study was to evaluate the chemical composition and anti-parasitic property of essential oil of C. sativum leaf on trophozoite of Trichomonas vaginalis. C. sativum was collected from Kermanshah city and essential oil was prepared by the C...

Lectins and glycosidases of known sugar specificity were used as probes to analyze the surface carbohydrate moieties of G. lamblia trophozoites and in particular to determine whether chitin or oligomeric D-GlcNAc is present in the trophozoite form of the parasite as well as on the cyst. Of 13 lectins with varying sugar specificity, only D-GlcNAc-specific lectins bound specifically to the tropho...

background: giardiasis is a one of the most prevalent intestinal parasitic diseases in human, treatment of this disease through medicinal plants is very important since parasite resistance to chemical drugs exists. thus, in this study, the in vitro anti-giardial activity of chloroformic extract of tanacetum parthenium and artemisia annua on cyst and trophozoite of giardia lamblia were separatel...

The apicomplexan parasite Cryptosporidium causes cryptosporidiosis, a diarrheal disease that can become chronic and life threatening in immunocompromised and malnourished people. There is no effective drug treatment for those most at risk of severe cryptosporidiosis. The disease pathology is due to a repeated cycle of host cell invasion and parasite replication that amplifies parasite numbers a...

OBJECTIVES The purpose of this study was to determine the mechanism by which iron chelation affects the trophozoite survival of Entamoeba histolytica. Fe2+ is a cofactor for E. histolytica alcohol dehydrogenase 2 (EhADH2), an essential bifunctional enzyme [alcohol dehydrogenase (ADH) and aldehyde dehydrogenase (ALDH)] in the glycolytic pathway of E. histolytica. METHODS We tested the effects ...

Plasmodium falciparum lysate, prepared from 2.7 x 10(7) ring-infected erythrocytes and incubated with hemoglobin in sodium acetate at pH 5, incorporated a mean of 1.6 nmol of ferriprotoporphyrin IX (FP) into hemozoin in 18 to 22 hr. A similar preparation of trophozoite lysate incorporated a mean of 3.6 nmol of FP into hemozoin in 4 to 6 hr. These findings indicate differences between heme polym...

INTRODUCTION Giardia lamblia is a flagellated protozoan parasite of man. Only 2 stages i.e. the trophozoite and the cyst forms are observed in the life cycle of Giardia. The Giardia infection is acquired from drinking water or by eating food which is contaminated with cysts. The symptoms of the Giardia infection are foul smelling diarrhoea, flatulence, steatorrhoea, etc. Stool samples from the ...

giardia is a flagellate protozoan with worldwide distribution that causes significant gastrointestinal diseases. the life cycle of the organism alternates between the active, proliferating trophozoite and the dormant cyst. 5-nitroimida-zoles have been used extensively in the treatment of amoebiasis, giardiasis, and trichomoniasis. we have previously synthesized some new analogues of metronidazo...
