A total 80 vegetable samples, (40 samples each during the rainy and dry season respectively) were purchased from market. The examined laboratory for presence intestinal parasites using sedimentation techniques microcopy. results revealed that out (...

Hydrogen peroxide reacts with ferrous Ascaris hemoglobin and converts it to oxyhemoglobin in a sequence of two reactions. The first is the reaction of ferrous Ascaris hemoglobin with hydrogen peroxide to form a stable product; the second is the reaction of this product with hydrogen peroxide to form oxyhemoglobin. Both reactions follow second order kinetics, since they are first order with resp...

biliary ascariasis is a common disease in certain geographical areas of the world. the adult form of the worm usually lives in the human intestine. biliary complications due to ascaris infestation are uncommon but are becoming an important clinical problem, as fatal cases have been reported in the literature. many authors have recommended traditional surgical treatment for removal of the worms....

background: parasitic nematodes cause animal and human diseases of major socio-economic importance worldwide. the suppression of parasite development at particular developmental stages could provide an alternative approach for nema-tode control. in this study, ascaris suum was used as a model system in the study of the differentially expressed genes in the infective l3 stage. methods: the gene ...

Ascaris lumbricoides is one of the most widespread human infections. Adult Ascaris worms inhabit the small intestine and themselves cause little disease in their normal habitat, except when there is heavy infection leading to intestinal obstruction. Wandering ascarids may reach abnormal situations when they migrate through the ampulla of Vater causing biliary obstruction with cholangitis and/or...

Children putatively immune to the large roundworm Ascaris lumbricoides were identified in an area of Nigeria where infection is hyperendemic. Immunity was associated with higher levels of serum ferritin, C-reactive protein, and eosinophil cationic protein, indicating ongoing acute phase or inflammatory processes. In contrast, children who were susceptible to the infection had little serological...
