Abstract

LOPEZ, Mauro et al. Coinfección por Aggregatibacter aphrophilus y SARS-CoV-2 con desenlace fatal. Acta bioquím. clín. latinoam. [online]. 2023, vol.57, n.4, pp.7-7. ISSN 0325-2957.

Aggregatibacter aphrophilus is a gram-negative coccobacillus with demanding nutritional requirements, which forces the microbiologist to use unconventional typification methods. The case of a patient who was admitted with a clinical history characterised by fever, headache and respiratory distress due to COVID-19 was reported. Slow-growing gram-negative coccobacillary colonies were recovered from the blood culture samples, which were finally typed as A. aphrophilus using matrix-assisted laser desorption ionization time-of-flight mass spectrometry (MALDI-TOF MS). Identifying this organism is difficult in our setting. As it is considered essential, building a network of laboratories that give response to diagnostic and technological needs is highly recommended.

Keywords : COVID-19; MALDI-TOF; Aggregatibacter aphrophilus; Laboratory network; HACEK.
