Evaluation of viral load and transcriptome changes in tracheal tissue of two hybrids of commercial broiler chickens infected with avian infectious bronchitis virus: a comparative study.

Infectious bronchitis virus (IBV) is one of the major threats to the poultry industry, with significant economic consequences. Despite strict measures, the disease is difficult to control worldwide. Experimental evidence demonstrates that the severity of IBV is affected by the genetic background of the chicken, and the selection of appropriate breeds can increase production efficiency.

Serologic survey for Coxiella burnetii phase II antibodies among slaughterhouse workers in Kerman, southeast of Iran.

Objective: To determine the presence of antibodies against phase II among slaughterhouse workers in Kerman, southeast of Iran.

Methods: The antibody titers of the serum samples were measured by enzyme-linked immuno sorbent assay using phase II Coxiella burnetii as the antigen [kit (Virion\Serion, Wurzburg, Germany) according to the manufacturer's protocol].

Results: The positive rate of IgG antibody was 68% in the slaughterhouse workers.
