To obtain a better understanding of the microbiota inhabiting the intestinal tract of wood-feeding lower termites, the European subterranean termite, Reticulitermes santonensis (Isoptera: Rhinotermitidae), was used as a model system. The diversity and structure of the bacterial community in the different niches of the gut, as well as the distribution and location of major bacterial phylotypes within the intestinal tract was evaluated using various molecular techniques such as clonal analysis, DNA fingerprinting, and fluorescence in situ hybridization. In addition, the symbiotic bacteria associated with the flagellate, Pyrsonympha vertens in the gut of the closely related Eastern subterranean termite, Reticulitermes flavipes , were phylogenetically characterized.

Chinensis and Kuruma prawn M. japonicus increased at 12 and 48 hours post-inoculum, but decreased sharply after 36 and 72 hours post-inoculum respectively. LPS inducible NOS activity also decreased significantly with the time elapsed in WSSV infected shrimps. Results of WSSV detection with the Dig-DNA Probe dot blot hybridization test showed that WSSV of the two penaeid species couldn't be detected until iNOS started decreasing.

Fluorescence in situ hybridization with 16S rRNA-targeted oligonucleotide probes was applied for analyzing the community of iron bacteria in wastewater from the Shengli Oil Field. Four 16S rRNA probes were designed, which were highly specific to iron bacteria Leptothrix, Sphaerotilus, Leptospirillum ferrooxidans, Leptospirillum ferriphilum and Acidithiobacillus spp.
