Evaluation of the Anti-Schistosomal Potential of Ginger-Loaded Chitosan Nanoparticles on : Histopathological, Ultrastructural, and Immunological Changes.

Chemotherapy is the most widely advocated method of Schistosome control. However, repeated chemotherapy leads to the emergence of drug-resistant Schistosoma strains. Therefore, efforts to find alternative drugs, especially those of natural origin, have risen globally.

Giardiasis Pattern among Different Age Categories: Childhood Assemblage B Proclaim Endemicity.

Background: Giardiasis is one of the commonest intestinal parasitic diseases that affects wide range of age groups. We aimed to detect the pattern of assemblages among symptomatic patients at the age of 2 up to 40 years.

Methods: Stool samples were collected from 278 patients and examined microscopically and genetically for giardiasis.

Multilocus genetic analysis of Cryptosporidium isolates from Saudi Arabia.

A total of 35 Cryptosporidium positive samples were collected from children in Jeddah city. The samples were microscopically examined with Ziehl Neelsen (ZN) and Auramin phenol (AP) staining methods. Cryptosporidium antigen was detected in the faecal samples by using the Cryptosporidium ELISA kit.

A new modified technique for concentrating intestinal parasites.

The present study evaluated the diagnostic performance of a modification of the formol ethyl acetate concentration technique, with the addition of 25% acetic acid as compared with formol ethyl acetate concentration technique (FEA) and fecal parasite concentrator kit Fresh fecal material, free of ova and parasites, was pooled in a ratio of 1:4 with 10% buffered formalin to prepare a standardized specimen. Sufficient volumes of formalin-fixed suspension of Giardia lamblia cysts, Entamoeba histolytica cysts, Cryptosporidium oocysts; Ascaris lumbricoides ova, Necator americanus, Taenia spp. and Hymenolepis nana were used to seed individually 3-ml portions of the fecal specimen.
