The KU-57788 cell line pathogenic strains represent the main causative serovars for Leptospirosis in humans and animals. The most common strains used in MAT panels belong to the three genomospecies L. interrogans, L. borgpetersenii and L. kirschneri (Table 1). All strains were cultured in Ellinghausen-McCullough-Johnson-Harris medium (Leptospira Medium Base EMJH BD, DifcoTM and Leptospira Enrichment EMJH DifcoTM, NJ, USA) at 28°C. Cultures were controlled for growth and motility by darkfield microscopy and were periodically subcultured into fresh media. Bacteria used for MALDI-TOF MS measurements and protein reference spectra generation were cultured for seven days.
