Providencia alcalifaciens as the presumptive cause of diarrhoea in dog.

A case of diarrhoea in a four-month-old golden retriever is described. On the basis of anamnesis and bacteriological examination, the diagnosis of bacterial enteritis due to Providencia alcalifaciens was reached. Although there are contradictory opinions about the role of this organism as the enteric pathogen, it seems that Providencia alcalifaciens should also be taken into consideration in the routine bacteriological diagnostics of diarrhoea in dogs.
