Given a curve of genus 3 with an unramified double cover, we give an explicit description of the associated Prym variety. We also describe how an unramified double cover of a non-hyperelliptic genus 3 curve can be mapped into the Jacobian of a curve of genus 2 over its field of definition and how this can be used to do Chabautyand Brauer-Manin type calculations for curves of genus 5 with an unr...

The study recorded for the first time in Egypt presence of tomato spotted wilt virus (TSWV) on cucurbits, which was confirmed using several serological tests, like double antibody sandwich ELISA (DAS-ELISA); Dot-blot assay and Immuno capture polymerase chain reaction (IC-PCR).  By Dot blot immunoassay test against TSWV antisera, ability thrips species Thrips tabaci (Lind), palmi (Karny), Frankl...

PRC is the most needed component for current blood transfusion. Plasma one of separation product from whole blood. These components are often discarded due to low plasma transfusion requirements. The residual contains natural ABO agglutinins that can be utilized as polyclonal antisera in grouping tests. This study aims determine quality pool antisera. research uses descriptive analytic design f...

Bacterial fish pathogens cause significant losses in rainbow trout farms. In farms, bacterial threatening diseases which has made it necessary to develop rapid methods for disease diagnosis. Serological techniques are applied with a small amount of antiserum and sample, preferred the diagnosis diseases. this study, formalin-killed antigens prepared from reference strains Lactococcus garvieae, Y...

Commercial antisera for serotyping 22 heat-labile antigens of Campylobacter jejuni and Campylobacter coli were evaluated by using 66 isolates from human and nonhuman sources. Test results were compared with results of tests using antisera produced at the Centers for Disease Control (CDC), Atlanta, Ga. All strains (three isolates of each of the 22 serotypes) were typeable with the CDC antisera. ...

Antisera have been raised to human leukemic blast cells from individual patients in mice rendered tolerant with cyclophosphamide to remission leukocytes from the same individual. 10 antisera were raised against acute myelogenous leukemia (AML) cells and 5 antisera were raised against acute lymphoblastic leukemia (ALL) cells. Antisera to AML cells were absorbed with ALL cells, and antisera to AL...
