Transformation of Brucella Species with Suicide and Broad Host-Range Plasmids
Time of Update: 2021-02-20
Thus, the ability to transformBrucella with suicide plasmids (to introduce transposons or cause allelic exchanges) or replicating plasmids (to perform complementation studies) is paramount in implementing molecular approaches to unravel the genetic basis forBrucella virulence determinants.

Immunoassay for Detection of IgA Antitissue Transglutaminase in Patients with Celiac Disease
Time of Update: 2021-02-20
Celiac disease is diagnosed by the demonstration of an altered intestinal mucosa in a jejunal biopsy specimen ( 3 ).
Serum IgA antibodies against endomysial antibodies (EMAs) are especially considered to be sensitive and highly specific markers for celiac disease ( 8 )( 9 ).
