ABSTRACT

 

Boroomand Z, Asasi K, Hosseinian SA, Mohammadi A, Karimi_Madab M, Simple rapid test for ciliary movement in trachea of chicken infected by bronquitis and influenza viruses,  Onl J Vet Res., 15 (4): 404-413, 2011. Mucociliary clearance is an important defense mechanism for respiratory airways. Authors describe a method to detect ciliary activity in trachea of chickens infected with infectious bronchitis virus (IBV) and influenza virus (AIV) with carbon pigment granules. Groups of ten 21 day old commercial broiler chicks were inoculated intranasally (IN) with 0.2 ml IBV,  0.2 ml AIV, or 0.2ml IBV and AIV. Controls were inoculated (IN) sterile PBS. In birds given IBV and/or AIV no pigment appeared in the larinx whereas in those inoculated with AIV, pigment was present in the larynx. Results suggest that IBV prevented ciliary movement whereas AIV did not.

 

Key words: carboniferous pigment granules, ciliary activity, ciliostasis, IBV, H9N2
