Multiple Dictyostelid Species Destroy Biofilms of Klebsiella oxytoca and Other Gram Negative Species

Abstract: Dictyostelids are free-living phagocytes that feed on bacteria in diverse habitats. When bacterial prey is in short supply or depleted, they undergo multicellular development culminating in the formation of dormant spores. In this work, we tested isolates representing four dictyostelid species from two genera (Dictyostelium and Polysphondylium) for the potential to feed on biofilms preformed on glass and polycarbonate surfaces. The abilities of dictyostelids were monitored for three hallmarks of activity: 1) s… Show more

“…The strains used in this study belong to species known for their ability to form biofilms: most notably, Hafnia sp, Serratia sp, and Klebsiella oxytoca [30][31][32]. As expected, it was two strains of Hafnia, namely, H. alvei strain 37 and H. paralvei strain 43, that had the best ability to form a biofilm, which is in concordance with the relevant scientific literature concerning genetically close strains [30].…”

“…The fact that both Klebsiella oxytoca strains used in this study (strain 9 and 14) formed biofilms in vitro, but only one (strain 14) formed intimate connections with the root system of duckweed, implied a higher level of biological specificity of the tested bacteria-plant interactions, which is also supported by similar studies [32,34].…”

“…The observation that D . discoideum secretes factors that mediate the degradation of bacterial biofilms supports and extends these conclusions [43]. We also found evidence for cheating during cooperative predation, which supports our conclusion since cheating is common in cooperative biological systems.…”

“…The lipopolysaccharides (complexes of crystalline cellulose with lipids) synthesized by gram negative bacteria (proteobacteria, actinobacteria) and fungi, too, could aid protection of the organism from host immune systems (phagocytosis) while concomitantly establishing an infection ( Cryptococcus neoformans, Pseudomonas spp., Vibrio spp.) or infestation in developing protists and marine invertebrates [ 9 14 , 41 , 43 , 48 , 102 104 ]. Reciprocally, an interesting utility of GH9 endoglucanases is to facilitate the symbiotic/ parasitic association between some fungi and bacteria of animal and plants hosts (macrophages, leguminous nodules of the rhizomes) by digesting the crystalline cellulose of the host.…”
