Genetic diversity and evolution of infectious bronchitis virus (IBV) in South African poultry and that of some neighbouring countries during the 2011-2020

Infectious bronchitis virus (IBV) (family Gammacoronavirus) considered to be the most significant diseases that has major economic losses within the poultry industry worldwide. Field isolates (n=385) grown in SPF embryonated chicken eggs at Deltamune (Pty) Laboratory, that originated in commercial flocks were collected from Botswana, Eswatini, Namibia and South Africa’s Eastern Cape, Free State, Gauteng, KwaZulu-Natal, Limpopo, Mpumalanga, North West, and Western Cape provinces from 2011-2020, were analysed in this study. A 745 bp region of the spike protein gene was amplified and sequenced, and phylogenetic analysis was performed. Twenty-four (6,2 %) samples contained mixed sequences from viral coinfections and were not evaluated further. In the remaining 364 isolates, 7 genetic lineages were identified. 184 (50,5%) viruses were identified as GI-19 (QX) strains and 78 (21,4%) as the GI-1 (Mass/H120) strain. 39 (10,7%) samples were identified as the GI-13 (4/91) lineage detected between 2011 and 2019, 29 (8,0%) as the GVI-1 (TC07-2) lineage detected from 2010-2020, 19 (5,2%) as the GI-23 (Var II) lineage from 2019-2020 with single isolates in 2010 and 2015, and 13 (3,6%) as the GI-11 (UFMG/G - Brazil) lineage detected from 2011-2020. Two (0.5%) viruses were closely related to GIV-1 (DE/072/92) lineages but were only isolated in 2011 and 2013. Three viruses from GI-1 and GI-13 may have been recombinants, but further analysis is required to confirm this.
