Electron microscopy of Giardia lamblia cysts.
The flagellated protozoan Giardia lamblia is a recognized public health problem. Intestinal infection can result in acute or chronic diarrhea with associated symptoms in humans. As part of a study to evaluate removal of G. lamblia cysts from drinking water by the processes of coagulation and dual-media filtration, we developed a methodology by using 5.0-microns-porosity membrane filters to eval...
متن کاملMechanisms of Giardia lamblia differentiation into cysts.
Microbiologists have long been intrigued by the ability of parasitic organisms to adapt to changes in the environment. Since most parasites occupy several niches during their journey between vectors and hosts, they have developed adaptive responses which allow them to survive under adverse conditions. Therefore, the life cycles of protozoan and helminthic parasites are excellent models with whi...
متن کاملDetection of Giardia lamblia Cysts in Surface Waters of Rasht City, Iran
Introduction: Giardia lamblia is a protozoan parasite with universal distribution in human populations. This infections transfer to human via contaminated foods and waters with Giardia cysts. The Knowledge on the incidence of this agent in the potential infection sources can provide valuable information for control and the spread of this parasite to human communities. This study was aimed to is...
متن کاملThe application of on-chip optofluidic microscopy for imaging Giardia lamblia trophozoites and cysts.
The optofluidic microscope (OFM) is a lensless, low-cost and highly compact on-chip device that can enable high-resolution microscopy imaging. The OFM performs imaging by flowing/scanning the target objects across a slanted hole array; by measuring the time-varying light transmission changes through the holes, we can then render images of the target objects at a resolution that is comparable to...
متن کاملComparison of three different methods for concentration and purification of giardia lamblia cysts
Background: Giardia lamblia is the most frequent human intestinal protozoan worldwide. Diagnosis of G. lamblia by microscopic examination of stool is common, but ELISA & IFA methods have been used in research and epidemiological studies recently. To produce polyclonal antibodies for designing ELISA & IFA kites molecular and genomic studies (PCR and parasitic culture) as well as other epidemiolo...
