Popis: | Given are the results of direct protein profiling of brucella strain collection using matrix laser desorption/ionization time-of-flight mass-spectrometry (MALDI-TOF MS). Standardized is the method for brucellosis agent culture disinfection and subsequent assessment. Obtained are 59 representative protein profiles of six major species ( B. melitensis, B. abortus, B. canis, B. ovis, B. neotomae ), which are included into electronic database of mass-spectra, integrated in Biotyper v 3.0 software (Bruker Daltonics, Germany). Analysis of mass-spectra of brucella strains under investigation revealed 17 genus-specific fragments within the mass range of 2000-20000 Da, the combination of which can be used for Brucella spp . identification. In addition, described are the fragments, specific for certain brucella species and strains, promising as markers for intraspecific differentiation. Based on the data received developed is a standardized algorithm of identification and differentiation of brucellosis agent cultures applying MALDI-TOF mass spectrometry. |
