Allantoic luid was harvested after death of embryo or on 3 dpi and tested for the presence of influenza A virus by haemagglutination (HA) test as per the OIE (11) using 0.5 per cent chicken red blood cell (RBC) suspension.
The indirect haemagglutination (IHA) serological test was positive for hydatid disease.
Mutations in the corresponding biosynthesis genes (ica operon) lead to a pleiotropic phenotype; the cells are biofilm and haemagglutination negative, less virulent and less adhesive on hydrophilic surfaces.
There are a variety of techniques available for serology: haemagglutination, Coombs' testing, immunofluorescence and many permutations of the classic ELISA (enzyme-linked immunosorbent assay).
Haemagglutination by canine parvovirus: serologic studies and diagnostic application.
For the haemagglutination and infectivity the S1 part is responsible because it comprises of serotype specific virus neutralizing epitopes (Cavanagh et al., 1986).
Humoral immune responses were evaluated by performing haemagglutination assay, mice lethality test and Jerne hemolytic plaque formation.
Because it is possible to differentiate between the individual classes of immunoglobulins by enzyme immunoassay, more precise statement about the status of patients can be made with these tests, than other tests like the Haemagglutination Inhibition assay or Complement fixation test.
Detection of a fourfold or greater rise in antibodies specific to JE virus as measured by haemagglutination inhibition (Hl) or plaque reduction neutralization assay (PRNT) in serum collected during the acute and convalescent phase of illness.
Serological tests include haemagglutination inhibition test, complement fixation test (CFT ), enzyme-linked immunosorbent assay (ELISA), antigen capture ELISA and neutralisation test, while molecular test used for diagnosis is RT-PCR.1 For the detection and isolation of virus, mosquito cell culture has been preferably used but due to low sensitivity it has been combined with RT-PCR for the swift diagnosis of dengue.
