Journal ArticleDOI
Isolation and phylogenetic analysis of bacteria with antimicrobial activities from the mediterranean sponges aplysina aerophoba and aplysina cavernicola
TL;DR: The high recovery of strains with antimicrobial activity suggests that marine sponges represent an ecological niche which harbors a hitherto largely uncharacterized microbial diversity and, concomitantly, a yet untapped metabolic potential.
Journal ArticleDOI
Temporal variation of the microbial community associated with the mediterranean sponge Aplysina aerophoba
TL;DR: It is postulated that a large fraction of sponge-associated bacteria resides permanently in the Aplysina aerophoba mesohyl pointing to a highly integrated interaction between the host sponge and associated microorganisms.
Book ChapterDOI
Microbial diversity of marine sponges.
Ute Hentschel,L. Fieseler,Markus Wehrl,Christine Gernert,Michael Steinert,Jörg Hacker,Matthias Horn +6 more
TL;DR: The recent application of molecular microbial ecology tools to sponge-microbe associations has revealed a glimpse into the biodiversity of these microbial communities, that is considered just the tip of the iceberg as discussed by the authors.
Journal ArticleDOI
Gene clusters encoding the cytotoxic necrotizing factor type 1, Prs-fimbriae and α-hemolysin form the pathogenicity island II of the uropathogenic Escherichia coli strain J96
TL;DR: Using phenotypic test systems and genotypic analysis, it has been shown that the mutant strain J96-M1 has lost the hlyII, prs and cnf1 genes.
Journal ArticleDOI
Microbial diversity in the marine sponge Aplysina cavernicola (formerly Verongia cavernicola) analyzed by fluorescence in situ hybridization (FISH)
TL;DR: The application of the “top-to-bottom approach” using 16S rRNA probes and in situ hybridization to assess the microbial diversity in Aplysina sponges is described for the first time.
