 Over a 20-year period, there was an increase in the number of cases of pastorella species infections presenting to a single centretropical tertiary hospital. The majority of these infections were caused by pastorella multicida, although other species such as pea, canis, pea, dagmatis, and others were also identified. These infections were often severe and invasive, with a higher rate of 30-day mortality. Polymicrobial infections were common, with other significant organisms being Staphylococcus aureus, Streptococcus pyagines, Group G Streptococcus, and Pseudomonas aeroginosa.
