Use of MALDI-TOF for identification and surveillance of gram-negative bacteria in captive wild psittacines.

Braz J Biol 2021 29;82:e233523. Epub 2021 Mar 29.

Universidade de São Paulo - USP, Departamento de Patologia da Faculdade de Medicina Veterinária e Zootecnia, São Paulo, SP, Brasil.

Microbiological studies of the sanitary and health status of psittacine birds that will be reintroduced is important in evaluating whether these animals act as carriers of pathogenic agents to other animals and humans. Matrix-assisted laser desorption/ionization time-of-flight mass spectrometry (MALDI-TOF MS) is a faster and more accurate method to identify bacteria than conventional microbiology methods. The aim of this study was to evaluate the health status of psittacines housed in captivity, by assessment of Gram-negative bacteria from fecal microbiota through MALDI- TOF MS identification.
