Fig. 3From: Genes involved in mitochondrial biogenesis and function may not show synchronised responses to mitochondria in shell gland of laying chickens under infectious bronchitis virus challengeMean mitochondrial count per cell in different segments of oviduct of laying hens at different time-points and IBV challenge. a Mitochondria in the shell gland (P = 0.0050). b Mitochondria in the isthmus (P = 0.2577). c. Mitochondria in the magnum (P = 0.0879). Superscripts (a,b) show significant difference between the control and IBV T strain challenged groups.
