Giardia duodenalis is a parasite of great medical interest due to the number infections it causes worldwide each year. Although research on epigenetic mechanisms in this protist has only begun recently, regulation already been shown have important roles encystation, antigenic variation, and resistance antibiotics Giardia. In work, we show that ortholog Sir2, GdSir2.4, involved silencing rRNA ex...

Sensitivities of DNA extraction methods and PCR methods for Giardia duodenalis were evaluated. A combination of the most sensitive methods, i.e., FTA filter paper and a PCR protocol using RH11/RH4 and GiarF/GiarR primers, showed no significant differences compared to immunofluorescence assay in terms of their sensitivities and specificities.

introduction: giardia and cryptosporidium are two of the most common parasitic protozoa that cause acute intestinal infections in children, all of the world. these parsites find in water environments, such as untreated water , wastewaters and even treated water. according to, a precise study on surface water was not done, in our country, necessity of precise study by ifa method that is prescise...

purpose: in the present work, clinical symptoms, serum immunoglobuline alteration and eosinophil count were investigated in the patients infected with giardia lamblia. materials and methods: in this regard, 50 persons infected with giardia and 50 healthy individuals were selected as the study and control groups respectively in tehran. sera of the groups were tested for igg, ige, iga levels and...

Waterway degradation in agricultural settings is caused by direct and diffuse sources of pollution. Waterway fencing focuses on reducing direct faecal contamination, but the extent to which it reduces overland surface runoff of pathogens is unknown. This study evaluated the potential of four riparian treatments to reduce Giardia in saturation excess surface runoff entering the waterway. Treatme...

Giardia and Cryptosporidium levels were determined by using a combined immunofluorescence test for source waters of 66 surface water treatment plants in 14 states and 1 Canadian province. The results showed that cysts and oocysts were widely dispersed in the aquatic environment. Giardia spp. were detected in 81% of the raw water samples. Cryptosporidium spp. were found in 87% of the raw water l...

Giardiasis, an intestinal protozoan infection caused by Giardia intestinalis, is common in southeastern Anatolia, Turkey. In this cross-sectional survey, to investigate the role of giardiasis on growth and psychomotor development, we studied 160 children aged 0-5 years. Data were collected using a structured questionnaire, anthropometry, Ankara Developmental Screening Inventory, and laboratory ...

Zinc supplementation has been shown to reduce the incidence and prevalence of diarrhea; however, its anti-diarrheal effect remains only partially understood. There is now growing evidence that zinc can have pathogen-specific protective effects. Giardiasis is a common yet neglected cause of acute-chronic diarrheal illness worldwide which causes disturbances in zinc metabolism of infected childre...
