TranscriptomicsStreptococcus agalactiae genes controlled by the MtaR transcription factor
The purpose of this study was to determine what S. agalactiae genes are under the control of the MtaR regulatory protein. Inactivation of the Streptococcus agalactiae mtaR gene resulted in the downregulation of 11 genes and the upregulation of 1 gene in the mtaR mutant. Genes involved in the uptak...

ProteomicsFirst comprehensive proteome analysis of lysine crotonylation in Streptococcus agalactiae, a pathogen causing meningoencephalitis in teleosts
In Homo sapiens, Streptococcus agalactiae is a common colonizer of the rectovaginal tract and a fundamental cause of neonatal and non-pregnant adults infectious diseases. It also causes infectious disease in fish which compromises food safety as well as possesses a zoonotic risk. Lysine crotonylatio...

TranscriptomicsThe Streptococcus agalactiae transcriptional landscape
Streptococcus agalactiae, also known as Group B streptococcus, emerged in the 1960s as a leading cause of septicemia and meningitis in neonates. It is also an increasing cause of infections in adults with underlying diseases. To characterize regulatory elements in this species we performed a genom...

TranscriptomicsLiaR Transcriptome in Streptococcus agalactiae
Streptococcus agalactiae (Group B Streptococcus, GBS) is a leading cause of early-onset neonatal bacterial infection. Evasion of innate immune defenses is critical to neonatal GBS disease pathogenesis. Effectors of the innate immune system such as antimicrobial peptides, as well as numerous antibi...

TranscriptomicsTranscriptome changes in Streptococcus agalactiae due to deletion of both the CiaR and LiaR Transcriptional Regulators
The CiaRH and LiaFSR two-component regulatory systems in Streptococcus agalactiae (Group B Streptococcus, GBS) are essential mediators of the organism s response to biologically important sources of environmental stress, and positive regulators of GBS virulence. Transcriptional profiling of CiaR mut...

TranscriptomicsTranscription profiling by array of Streptococcus agalactiae strain 2603 V/R and isogenic Delta_csrRS mutant grown in the presence or in the absence of glucose
Comparative global gene expression analysis of the 2603 V/R Streptococcus agalactiae (Group B streptococcus, GBS) strain grown in a medium devoid of sugars versus bacteria incubated for 30 min in 55 mM glucose medium. To investigate whether glucose-dependent regulation of gene expression was modulat...

TranscriptomicsRNA-seq of a Streptococcus agalactiae A909 mutant strain deleted for the pleiotropic transcriptional regulator CcpA
The commensal bacterium Streptococcus agalactiae is responsible for various infections in a wide variety of hosts including humans. Its broad spectrum of hosts shows its ability to acquire nutrients in variable conditions. The carbon catabolite repression allows bacteria to prioritize the uptake and...

TranscriptomicsRemodeling of the Streptococcus agalactiae transcriptome in response to growth temperature
To understand the extent to which GBS modify gene expression in response to temperatures encountered in the various hosts, we conducted a whole genome transcriptome analysis of organisms grown at 30°C and 40°C. We identified extensive transcriptome remodeling at various stages of growth, especially ...
