Dog bite wound infection by Pasteurella dagmatis misidentified as Pasteurella pneumotropica by automated system Vitek 2.

摘要

Human pasteurellosis are most often caused by dog and cat bites, resulting in cellulitis and subcutaneous abscesses. The second most common site of infection or colonization is the respiratory tract. Systemic diseases are uncommon and mostly occur in patients with underlying diseases. Pasteurella multocida is the most frequent species in human infections, but other species may be involved, such as Pas-teurella canis, Pasteurella dagmatis, and Pasteurella stomatis (Allison and Clarridge, 2005; David et al., 1996; Escande and Lion, 1993; Gautier-Lerestif et al., 2003; Hoist et al., 1992; Talan et al., 1999). Automated systems are commonly used for Pasteurella identification. However, the failure of commercial systems to satisfactorily identify microorganisms is of concern, and unusual identification should be correlated with patient's clinical pictures. We are reporting here a case of misidentification of P. dagmatis by automated system Vitek 2.
