Project description:Transcriptome analysis of Streptococcus agalactiae (group B Streptococcus) grown under control conditions or coincubated with serine hydroxamate to induce the bacterial stringent response
Project description:Streptococcus agalactiae (Lancefield’s group B Streptococcus, GBS) is a major bacterial species of genus Streptococcus and has medical and veterinary importance by affecting mainly humans (Maione et al., 2005; Johri et al., 2006), cattle (Keefe, 1997) and fish (Mian et al., 2009). The GBS is the most important pathogen for the Nile tilapia, a global commodity of the aquaculture sector, causing outbreaks of septicemia and meningoencephalitis (Hernández et al., 2009; Mian et al., 2009).
Project description:Total RNA was isolated from mid-log phase Streptococcus agalactiae cells deficient in SczA (∆sczA strain GU2791), grown in Todd-Hewitt broth (THB) medium and sequenced using Illumina NextSeq500.
Project description:Total RNA was isolated from mid-log phase Streptococcus agalactiae cells deficient in CovR (∆covR strain GU2400), grown in Todd-Hewitt broth (THB) medium and sequenced using Illumina NextSeq500
Project description:Total RNA was isolated from mid-log phase Streptococcus agalactiae cells deficient in CopY (∆copY strain GU2857), grown in Todd-Hewitt broth (THB) medium and sequenced using Illumina NextSeq500.
Project description:Total RNA was isolated from mid-log phase Streptococcus agalactiae 874391 wild-type cells grown in Todd-Hewitt broth (THB) medium and sequenced using Illumina NextSeq500

The GBS is the most important pathogen for the Nile tilapia, a global commodity of the aquaculture sector, causing outbreaks of septicemia and meningoencephalitis (Hernández et al., 2009; Mian et al., 2009). This study aimed to evaluate the global abundancy of proteins among the main genotypes of GBS isolated from fish identified in Brazil using a label free shotgun liquid chromatography-ultra definition mass spectrometry (LC-UDMSE) approach and to compare the differential expression of proteins identified between isolates from fish and human.
Project description:In the transition from recto-vaginal colonizing organism to invasive pathogen, Streptococcus agalactiae (Group B Streptococcus, GBS) must adapt to changes in host temperature, including elevated temperatures due to host fever. To identify genes important to the survival of GBS in response to heat stress, transcriptional profiling was performed using DNA microarray analysis, comparing GBS grown at normal temperature (37˚C) to GBS exposed to elevated temperature (42˚C).
Project description:Total RNA was isolated from mid-log phase Streptococcus agalactiae cells deficient in SczA (∆sczA strain GU2791), grown in Todd-Hewitt broth (THB) medium supplemented with 0.5 mM Cu and sequenced using Illumina NextSeq500.
Project description:Total RNA was isolated from mid-log phase Streptococcus agalactiae cells deficient in SczA (∆sczA strain GU2791), grown in Todd-Hewitt broth (THB) medium supplemented with 0.25 mM Zn and sequenced using Illumina NextSeq500.
