“…Out of 74 lung affections, with lesions characteristic of Pasteurellaceae (in particular fibrinous pleuropneumonia in apical lobes associated to pleural exudation); M. haemolytica was the causative agent in 51 cases, and P. multocida in 23 cases. Strains of Mannheimia, generally identified with biochemical methods, it is likely, on the basis of what is reported by some researchers (Villard et al, 2006;Posautz et al, 2014), that a certain proportion may correspond to the T biotype, recently reclassified as Pasteurella trehalosi. Pasteurellosis, both for domestic and wild ruminants, can be fatal in severe or complicated cases, when the lesions involve more of the lung tissue, over the classical localization in apical lobes.…”
