RESUMEN
Mucorales are a large order of ubiquitous saprophytic zygomycete fungi and act as opportunistic pathogens in humans. In pediatric patients, little is known about the role of Mucorales in airway colonization and infection or their role as contaminants of respiratory samples. Currently, polymerase chain reaction (PCR) is the most sensitive mode of detection Mucorales in clinical specimen. In this study, we aimed to determine the prevalence of Mucorales in bronchoalveolar lavage samples (BAL) from a large, diverse group of pediatric patients. We performed commercial Mucorales PCR (MucorGenius®, Pathonostics, Maastricht, NL, USA) on 102 thawed BAL samples of 100 patients. Mucorales PCR was negative in all samples. Our data suggest that Mucorales spp. have a low prevalence in paediatric airways and do not frequently contaminate pediatric BAL samples.

The European Society for Clinical Microbiology and Infectious Diseases recommends 3rd generation cephalosporins and metronidazole for empirical treatment of community-acquired brain abscesses. In 53 retrospectively analyzed pediatric patients with community-acquired brain abscesses at a German University Hospital Staphylococcus aureus was identified as a relevant pathogen (21%). Therefore, it may be reasonable to cover S. aureus when selecting empirical therapy.
