Report on five cases of tularaemic pneumonia in a tularaemia outbreak in Spain

A report is given on five cases of atypical tularaemic pneumonia selected from among 140 cases of tularaemic infection in a previously reported outbreak occurring in 1997. Prior to this outbreak no human cases of tularaemia had been reported in Spain. All cases were diagnosed serologically. All five patients reported on here had a mild form of the disease, which was treated successfully with streptomycin in four cases and ciprofloxacin in one case. Tularaemic pneumonia should be considered in the differential diagnosis of atypical pneumonia in Spain, especially in hunters and other persons who handle animal carcasses.
