The most characteristic finding in non-typhoid salmonella (NTS) infection is acute food related outbreaks of gastroenteritis, which is usually benign and self-limiting. However, more serious extraintestinal findings, such as bacteraemia and focal infections localized to any organ may appear. The objective of this paper is to describe the most important characteristic of the extraintestinal infections due to NTS serotypes observed in University Hospital, in Cracow between January 2000 and December 2006. To do so, we reviewed the clinical presentations, risk groups, complications and outcomes of in-patients, in which extraintestinal non-typhoid Salmonella serotypes were isolated, applying a clinomicrobiological protocol. Out of 30 patients with either bacteraemias (n = 22) or focal salmonella infections (n = 8), 12 had malignancies, 17 had immune dysfunction state, 9 had gastrointestinal disorders and 8 had chronic heart, pulmonary or kidney disease. Four of these patients (13%) who had hematological malignancies (2), renal transplantation (1) and pulmonary disease (1) died. Regarding the clinical picture, primary bacteraemia and focal infections occurred with similar frequency (33.3% and 26.7%, respectively); the remaining were bacteraemias secondary to gastroenteritis. The incidence rate (mean 0.30/1000 hospital admission/year) increased steadily from 0.19/1000 to 0.32/1000 hospital admission during the study period. From 30 Salmonella isolates from extraintestinal samples collected, only four isolates were resistant to ampicillin, ciprofloxacin or trimethoprim-sulfamethoxazole. This finding indicate that multidrug resistance does not represent a serious problem among NTS serotypes collected from the our medical center as monitored over a period of 7 years. Given this presentation, clinicians need to have a high index of suspicion and to consider preemptive therapy, especially in elderly patients who are likely to develop severe immunosuppression following interventions.
