Figure 6From: Immunogenicity and protection of a Pasteurella multocida strain with a truncated lipopolysaccharide outer core in ducksBacterial loads and animal survival post-challenge. A The bacterial loads of each immunization group (n = 4/group) in the blood, liver, spleen and lung were determined as CFU/mL or CFU/g at 24 h post-challenge. B Animal mortality (n = 10/group) was also recorded daily post-challenge within a 14-day period.Back to article page
