Biological Characterisation and Pathogenicity of a Pasteurella multocida Isolate from Sheep in Morocco

Journal of Agricultural Science and Technology(A) 2021年第1期11卷 53-64页

In this study,55 suspected pasteurellosis clinical cases from different provinces of Morocco were *** analysis revealed that 47%of samples were positive for Pasteurella multocida,all typed as serogroup A,and 11%positive for Mannheimia *** isolates were recovered from 26 *** positive samples,and characterized by biochemical and molecular typing *** these isolates,two strains(S13 and S14)were selected for genes(RNA16S and rpoB)sequence analysis and virulence study in mice,guinea pigs and *** study showed similarities of both S14 and S13 isolates with strains from other *** laboratory animals,the strain S14 was more virulent than S13 and induced severe illness in *** high mortality of infected mice suggests that this model may represent an alternative for testing pathogenicity and vaccine efficacy.
