additional information a Hi2019DELTAdmsA strain does not show any defects in anaerobic growth on chemically defined medium (CDM), and viability is also unaffected. Although Hi2019DELTAdmsA exhibits increased biofilm formation in vitro and greater resistance to hypochlorite killing compared to the isogenic wild-type strain, its survival in contact with primary human neutrophils, in infections of cultured tissue cells, or in a mouse model of lung infection is reduced compared to wild-type, Hi2019WT. The tissue cell infection model reveals a 2fold decrease in intracellular survival, while in the mouse model of lung infection Hi2019DELTAdmsA is strongly attenuated and below detection levels at 48 h post-inoculation. While Hi2019WT is recovered in approximately equal numbers from bronchoalveolar lavage fluid (BALF) and lung tissue, survival of Hi2019DELTAdmsA is reduced in lung tissue compared to BALF samples, indicating that Hi2019DELTAdmsA has reduced access to or survival in the intracellular niche Haemophilus influenzae

General Information

General Information Comment Organism
malfunction loss of DmsABC reduces Haemophilus influenzae fitness in interactions with human bronchial epithelial cells and neutrophils. Mutant Hi2019DELTAdmsA shows an increase in biofilm formation and increased resistance to HOCl Haemophilus influenzae
additional information the DmsABC sulfoxide reductase is encoded by a five-gene operon, dmsABCDE that is completely conserved in genomes of Haemophilus influenzae strains. The dmsABC genes encode the structural components of the enzyme, namely, the catalytic subunit DmsA, an iron-sulfur cluster-containing electron transfer subunit, DmsB, and the membrane anchor subunit, DmsC. The dmsDE genes encode two chaperones Haemophilus influenzae
physiological function DmsABC, a putative dimethylsulfoxide (DMSO) reductase, is required for fitness of the respiratory pathogen Haemophilus influenzae (Hi) in different models of infection. DmsABC sulfoxide reductase supports virulence in non-typeable Haemophilus influenzae. A role for DmsABC in Haemophilus influenzae infection, the conditions under which DmsABC is required in this bacterium are closely linked to interactions with the host. DmsABC is required for successful NTHi lung infection in mice. Under in vitro conditions, DmsABC is not required for Haemophilus influenzae viability Haemophilus influenzae
