Leptospirosis is a global zoonotic bacterial disease which is a threat for humans and most mammals. Bacterin vaccines for leptospirosis are available however they are severely limited in cross protection between serogroups. Leptospira typically colonize the kidneys of reservoir hosts where they are subsequently shed in the urine and persist in the environment and can thus be indirectly or directly transmitted to incidental hosts. Leptospira borgpetersenii serovar Hardjo is the primary cause of leptospirosis in cattle which can result in abortion, unhealthy calves, and rebreed problems. This dataset comprises proteomic profiles of four strains of L. borgpetersenii serovar Hardjo propagated at the routinely utilized culture temperature of 29 °C, and a newly achieved culture temperature of 37 °C, which more closely emulates the temperature of an infected host. The strains analyzed include JB197 (established strain that causes Hardjo atypical acute disease in the hamster model of leptospirosis), HB203 (established strain, causes typical chronic disease in hamsters), as well as TC129 and TC273 (recently isolated strains from the central United States). Differential expression profiles were detected not only between strains but also within strains between culture temperatures. Mass spectrometry data are available via ProteomeXchange with identifier PXD032831.

Guinea pigs represent an important model for a number of infectious and non-infectious pulmonary diseases. The guinea pig genome has recently been sequenced to full coverage, opening up new research avenues using genomics, transcriptomics and proteomics techniques in this species. In order to further annotate the guinea pig genome and to facilitate future pulmonary proteomics in this species we constructed a 2-D guinea pig proteome map including 486 protein identifications and post translational modifications (PTMs). The map has been up-loaded to the UCD 2D-PAGE open access database (http://proteomics-portal.ucd.ie/). Transit peptides, N-terminal acetylations and other PTMs are available via Peptideatlas (ftp://PASS00619:NM455hi@ftp.peptideatlas.org/). This dataset is associated with a research article published in the Journal of Proteomics [1].
