alfalfa crops were surveyed for the incidence of alfalfa mosaic virus (amv), cucumber mosaic virus (cmv), peanut stunt virus (psv), bean leaf roll virus (blrv), bean yellow mosaic virus (bymv) and bean common mosaic virus (bcmv) in the major growing areas in the southeast and central regions of iran. samples were collected between may 2009 and march 2011 and analyzed for viral infection initial...

Serological testing is widely used to monitor swine herds for Actinobacillus pleuropneumoniae (APP). Several serological tests are presently used, most often the complement fixation test, the long-chain lipopolysaccharide enzyme-linked immunosorbent assay (ELISA), and the ApxIV ELISA. Serological testing occasionally generates ambiguous results. In such situations, bacterial isolation and polym...

We read with interest the recent report by Garner et al. [l], in which anti-E was detected early in pregnancy solely through the use of enzymetreated red blood cells (RBC). The serological reactivity of this anti-E changed dramatically during pregnancy; the antibody became detectable by the indirect antiglobulin test, and at 37 weeks’ gestation had a titer of 512. Delivery at 40 weeks’ gestatio...

The early recognised risk of transmitting infectious diseases by blood components and the consequent introduction of mandatory serological testing of blood donations for infectious diseases has pushed the development of various automated serological testing systems. As correct performance of preand post-analytical work steps is essential for obtaining valid test results, the need for standardis...
