Comparison of single strains of four serotypes of Pasteurella haemolytica biotype A in experimental pneumonia of sheep.
Single strains of serotypes A1, A2, A7 and A9 of Pasteurella haemolytica were separately used in combination with Mycoplasma ovipneumoniae to reproduce pneumonia. Macroscopically and microscopically the pneumonias associated with individual serotypes were similar and it is concluded that serotypes of P haemolytica isolated with low frequency in field disease may be equally virulent to common serotypes.
