New Brucella abortus S19 Mutant to Improve Distinction Between Infected and Vaccinated Animals
Background: Using Brucella abortus Strain 19 (S19) to control bovine brucellosis is restricted due to induce antibodies to the O-side chain of the smooth lipopolysaccharide (LPS) which may be difficult to differentiate vaccinated and infected animals. Furthermore, it is virulent for humans and can induce abortion to cattle. Objectives: The aim of...
متن کاملHepatitis A virus hemagglutination and a test for hemagglutination inhibition antibodies.
Like enteroviruses, hepatitis A virus (HAV) hemagglutinated various species of erythrocytes under similar conditions. HAV-specific antibodies in both acute- and convalescent-phase sera were found to inhibit hemagglutination. The HAV hemagglutination inhibition test can be used for diagnosis, epidemiological surveillance, and vaccine assessment.
متن کاملDifferentiation of serum antibodies from pigs vaccinated or infected with Aujeszky's disease virus by a competitive enzyme immunoassay.
A competitive enzyme immunoassay was developed to detect antibodies to a glycoprotein (gI) of Aujeszky's disease virus. Infected cell monolayers were used as antigen and a monoclonal antibody directed against an epitope of gI as indicator antibody. It was demonstrated that pigs vaccinated with the Bartha, BUK or NIA-4 strains did not produce antibody to the epitope of gI, whereas all wild-type ...
متن کاملDetection of Infectious Bronchitis Virus in Allantioc Fluid by Rapid Hemagglutination Test.
To detect the presence of infectious bronchitis virus (IBV) in infected allantoic fluid (AF) of SPF embryonated eggs rapid hemagglutination (HA) activity after treatment with neuraminidase enzyme was used. Twenty IBV suspected materials were inoculated in SPF embryonated eggs via chorioallantoic cavity. Harvested AFs were treated with neuraminidase enzyme and the presence of IBV was detected by...
متن کاملHemagglutination by rabies virus.
Goose erythrocytes were agglutinated by five strains of rabies virus grown in monolayer cell cultures at pH 6.4 and at 0 to 4 C. Hemagglutination was not affected by the cell type in which the virus was grown. Prerequisites for occurrence of hemagglutination are absence of hemagglutination inhibitors (such as those contained in bovine serum) and a relatively high virus concentration (> 10(6) pl...
