During the year 2000-2001, P. multocida isolated from natural outbreaks of fowl cholera were subjected to somatic serotyping for the first time in Pakistan. Serotyping was carried out by the gel-diffusion precipitin test. P. multocida serotypes 1 predominated with the percentage of 47.62, followed by serotypes 3(28.57%), 4(14.29%) and 12(09.52%). All the serotypes found highly virulent with 100% mortality after challenge by serotypes 1 and 3, 80% by serotypes 4 and 60% by serotypes 12.
