چکیده
Etiologic Agent Schistosomiasis is a disease caused by parasitic worm of genus Schistosoma [1]. It belongs to phylum Platyhelminthes, class Trematoda and genus Schistosoma [2]. Most human infections are caused by the three species: S. mansoni, S. haematobium, and S. japonicum [3]. There are two more species S. intercalatum and S. mekongi known to cause Schistosomiasis [3]. The most infections caused by a particular species appears to be more a matter of geographic distribution of the species rather than contagiousness of the species. New species has been reported in Malaysia [4]. Humans are the definitive hosts for S. mansoni, S. haematobium, and S. japonicum [4]. All of these species are blood flukes.

متن کاملA hydrogel based rapid test method for detection of Escherichia coli (E. coli) in contaminated water samples.
We have formulated a new chemical composition for rapid detection of Escherichia coli (E. coli) with currently available enzymatic substrates. We have evaluated the performance of the new chemical composition with different kinds of bacteria, and metallic and ionic interferences and optimized the chemical composition for rapid and specific detection of E. coli. We used a novel hydrogel based po...

We are witnessing a proliferation of massive visual data. Unfortunately scaling existing computer vision algorithms to large datasets leaves researchers repeatedly solving the same algorithmic, logistical, and infrastructural problems. Our goal is to democratize computer vision; one should not have to be a computer vision, big data and distributed computing expert to have access to state-of-the...
