Reptile-associated Salmonellosis in a Breastfed Infant

Background: Although salmonellosis is one of the most common childhood illnesses associated with enteric bacteria, breastfed babies do not often get infected with Salmonella. In such cases it is therefore necessary to look carefully for the source of infection. Patient: It is reported an 8-week-old female infant with acute haemorrhagic diarrhoea and fever. With symptomatic therapy and breast-feeding her condition improved without antibiotic therapy. Microbiological diagnosis and subtyping identified infection with Salmonella enterica serovar Pomona. The source of the infection was a bearded dragon (Pogona spp.) living in a neighborhood household. Monitoring of the child showed shedding of the bacterium over a nine month period. Conclusion: In all cases of salmonellosis in breastfed babies, the source of infection should be carefully determined. Small numbers of bacteria can cause a symptomatic infection in this age group. Therefore an intensive search of the transmission route is indicated to develop prevention strategies.
