'Disguised' bacteria can still be confused in tests even after outbreak that killed 15 babies
An emerging bacterium, Phytobacter diazotrophicus, continues to be misidentified as Pantoea in laboratory tests, despite causing a deadly outbreak among newborns in Brazil in 2013.
In 2013, Brazil experienced a severe outbreak of sepsis that affected 65 newborns, resulting in the tragic deaths of 15 premature infants. This outbreak led to the identification of a new and hard-to-detect bacterium known as Phytobacter diazotrophicus. Despite the recognition of the bacterium’s role in the outbreak, laboratories continue to struggle with its correct identification, often misclassifying it as Pantoea, which has significant implications for diagnosis and treatment of infections.
According to Brazilian microbiologist Marcelo Pillonetto, automated identification systems and biochemical tests used in various labs both in Brazil and internationally are still prone to errors. The continued misidentification of Phytobacter diazotrophicus compromises the ability of healthcare providers to manage infections effectively, as treatments and interventions are based on inaccurate results. This challenge highlights the necessity for improved diagnostic methods and greater awareness within the medical community regarding emerging pathogens.
The narrative surrounding Phytobacter diazotrophicus has been documented in a film titled "A Saga do Phytobacter", which was released this year with funding from the Secretaria de Estado da Ciência, Tecnologia e Ensino Superior in Paraná. The documentary sheds light on the bacterium’s impact and the broader implications for public health and microbiological research, encouraging ongoing vigilance and advancement in the identification of bacterial pathogens.
