Lethal Synergism between Influenza and Streptococcus pneumoniae
The devastating synergism of bacterial pneumonia with influenza viral infections left its mark on the world over the last century. Although the details of pathogenesis remain unclear, the synergism is related to a variety of factors including pulmonary epithelial barrier damage which exposes receptors that influence bacterial adherence and the triggering of an exaggerated innate immune response...
متن کاملCompetition and coexistence between Streptococcus mutans and Streptococcus sanguinis in the dental biofilm.
The human mucosal surface is colonized by the indigenous microflora, which normally maintains an ecological balance among different species. Certain environmental or biological factors, however, may trigger disruption of this balance, leading to microbial diseases. In this study, we used two oral bacterial species, Streptococcus mutans and Streptococcus sanguinis (formerly S. sanguis), as a mod...
متن کاملStreptococcal antagonism in oral biofilms: Streptococcus sanguinis and Streptococcus gordonii interference with Streptococcus mutans.
Biofilms are polymicrobial, with diverse bacterial species competing for limited space and nutrients. Under healthy conditions, the different species in biofilms maintain an ecological balance. This balance can be disturbed by environmental factors and interspecies interactions. These perturbations can enable dominant growth of certain species, leading to disease. To model clinically relevant i...
متن کاملInteractions between oral bacteria: inhibition of Streptococcus mutans bacteriocin production by Streptococcus gordonii.
Streptococcus mutans has been recognized as an important etiological agent in human dental caries. Some strains of S. mutans also produce bacteriocins. In this study, we sought to demonstrate that bacteriocin production by S. mutans strains GS5 and BM71 was mediated by quorum sensing, which is dependent on a competence-stimulating peptide (CSP) signaling system encoded by the com genes. We also...
متن کاملSynergism between efrotomycin and bottromycin.
BETTINA M. FROST, MARY E. VALIANT and EUGENE L. DULANEY Merck Institute for Therapeutic Research Rahway, New Jersey, 07065, U.S.A. (Received for publication May 26, 1979) Efrotomycin1) is a narrow spectrum antibiotic which is most active in vitro against representative species of Pasteurella, Moraxella and Corynebacterium2) . The in vivo activity, however, is much better than one would expect f...
