The ability to utilize mucin affects the regulation of virulence gene expression in Streptococcus pneumoniae. [PDF]
, 2008 Streptococcus pneumoniae colonizes the mucin-rich environment of the nasopharynx. As colonization may be the first stage of infection, investigation was carried out as to whether the pneumococcus could utilize mucin as a source of nutrient and whether ...

Effects of α and β-adrenergic signaling on innate immunity and Porphyromonas gingivalis virulence in an invertebrate model [PDF]
, 2022 To investigate the role of adrenergic signalling (AS) in the host immune response and Porphyromonas gingivalis virulence, we compared norepinephrine (NE) and isoproterenol (ISO) responses in Galleria mellonella. P.

Resistance of Animal Strains of Pseudomonas aeruginosa to Carbapenems
Frontiers in Microbiology, 2017 Carbapenems are major antibiotics reserved to human medicine. This study aimed to investigate the mechanisms of carbapenem resistance of a selection of Pseudomonas aeruginosa veterinary strains from the French network Resapath. Thirty (5.7%) imipenem and/

TroA of Streptococcus suis is required for manganese acquisition and full virulence [PDF]
, 2011 Streptococcus suis causes infections in pigs and occasionally in humans resulting in 23 manifestations as meningitis, sepsis, arthritis and septic shock. For survival within the 24 host, S. suis requires numerous nutrients including trace metals.
