Brucella species are Gram-negative bacteria that cause BrucelIosis, also known as Mediterranean or Malta fever, a highly contagious and chronic disease that occurs worldwide. Brucellosis may affect human after close contact with infected animal secretions and by ingestion of contaminated animal products, such as those made with unpausterized milk or undercooked meat. Livestock, including cattle, sheep, goats, pigs and dogs are the most common reservoirs for Brucella bacteria, which the detection stilI relies on microbiological culture and serological tests. However, in the last decade, matrix-assisted laser desorption ionization time-of-flight mass spectrometry (MALDI- TOF MS) has been used for microrganism identification at genus and species leveI. CurrentIy, MALDI-TOF MS is being used as a rapid, cost effective and reliable methodology for bacteria identification even at the subspecies leveI. Here we show that MALDI- TOF MS is useful for Brucella identification and differentiation, B. abortus (strains 544, S2308, 19 and RB51), B. suis, B. ovis and B. canis reference samples were grown and, after ethanol inactivation, proteins were extracted with formic acidlacetonitrile. Mass spectra were acquired with alpha-cyano-4-hydroxy cinnamic acid in an Autoflex III Smartbeam mass spectrometer (Bruker Daltonics). MALDI Biotyper software (Bruker Daltonics) dendogram analysis provided that the mass spectra profiles (MSPs) obtained can distinguish alI the species of Brucella studied herein. Moreover, fingerprints of the wild-type S2308 and vaccine 19 and RB51 B. abortus strains are clearly different. The next step wilI be to use these MSPs to detect and identify Brucella from infected cattle. Financial support: Embrapa, FUNDECT, CNPq and CAPES.
