The plant microbiome represents an enormous untapped resource for discovering novel genes and bioactive compounds. Previously, we isolated Pseudomonas sp. SH-C52 from the rhizosphere of sugar beet plants grown in a soil suppressive to the fungal pathogen Rhizoctonia solani and showed that its antifungal activity is, in part, attributed to the production of the chlorinated 9-amino-acid lipopepti...

A new seminested PCR typing assay has been extended to identify the important veterinary rotavirus serotypes G5, G6, G10, and G11, as well as the rare human serotype G8. The specificity of the method was evaluated with 30 standard laboratory strains of the G1 to G6 and G8 to G11 types. Rotavirus strain types G6 and G8, not previously recognized in pigs, were identified in field specimens of por...

The flagellated protozoan Giardia duodenalis is a parasite of the upper part of the small intestine of mammals, including humans, and an interesting biological model. Giardia harbors a single 14-3-3 isoform, a multifunctional protein family, that is modified at the C terminus by polyglycylation, an unusual post-translational modification consisting of the covalent addition of one or multiple gl...

Monolayers of intestine 407 (Int-407) cells were infected with the virulent Salmonella typhimurium strain C52, and the adhesion to and invasion of these cells were studied. The effects of the multiplicity of infection and growth phase of the bacteria (logarithmic versus stationary) on the interaction with eukaryotic cells were investigated. In contrast to other reports, we found no differences ...

Using NACO on the VLT in the imaging mode we have detected an object at a distance of only 0.7 arcsec from GQ Lup. The object turns out to be co-moving. We have taken two K-band spectra with a resolution of λ/∆λ = 700. In here, we analyze the spectra in detail. We show that the shape of spectrum is not spoiled by differences in the Strehl ratio in the blue and in the red part, as well as differ...

The regulation of the citrate synthase (gltA) and ATP/ADP translocase (tlc) genes of the obligate intracellular bacterium, Rickettsia prowazekii, was analyzed in rickettsia-infected respiration-deficient G14 cells. The level of the gltA mRNAII and the tlc mRNA was much lower in the total RNA isolated from the infected G14 cells grown in 1 g/l glucose (low glucose, GL) medium than in that from i...

The metacestode of Echinococcus multilocularis is surrounded by a carbohydrate-rich laminated layer, which plays a key role in the establishment of the infection in the mammalian host. A major component of the laminated layer is an antigen referred to as Em2(G11). This highly species-specific antigen has been used for serodiagnoses of alveolar echinococcosis and is suggested to contain carbohyd...
