일반 설명
Fluorescent In Situ Hybridization technique (FISH) is based on the hybridization of fluorescent labeled oligonucleotide probe to a specific complementary DNA or RNA sequence in whole and intact cells.1 Microbial FISH allows the visualization, identification and isolation of bacteria due to recognition of ribosomal RNA also in unculturable samples.2
FISH technique can serve as a powerful tool in the microbiome research field by allowing the observation of native microbial populations in diverse microbiome environments, such as samples from human origin (blood3 and tissue4), microbial ecology (solid biofilms5 and aquatic systems6) and plants7.
Prokaryotic single cell life forms are divided into two domains, called Bacteria and Archaea, originally categorized as Eubacteria and Archaebacteria.8 However both terms, Eubacteria and Bacteria are still being used in microbiology.
Eubacteria probe recognizes most bacteria as it is complementary to a portion
of 16S rRNA found in almost all bacteria.9,10
FISH technique was successfully used to identify different bacteria with the universal bacterial probe in various samples such as, pure culture (as described in the figure legends), blood cultures10,11, periapical tooth lesions12, saliva13, biofilms from voice prostheses14, subgingival biofilm15, aortic wall tissue16, buccal epithelial cells, pure culture and cell culture17, intestine tissue embedded in paraffin18, necrotizing fasciitis and pure culture19, colon sections embedded in paraffin20,21, cancer tissues22,23, environmental samples24 and gut of the medicinal leech25. The probe can also be used for combined technique of FISH and Flow cytometric analysis. 9,26,27
It is strongly recommended to include positive and negative controls in FISH assays to ensure specific binding of the probe of interest and appropriate protocol conditions. We offer positive (MBD0032/33) and negative (MBD0034/35) control probes, that accompany the specific probe of interest.

Molecular structures and sequences are generally more revealing of evolutionary relationships than are classical phenotypes (particularly so among microorganisms). Consequently, the basis for the definition of taxa has progressively shifted from the organismal to the cellular to the molecular level.

Plastic marine debris (PMD) affects spatial scales of life from microbes to whales. However, understanding interactions between plastic and microbes in the "Plastisphere"-the thin layer of life on the surface of PMD-has been technology-limited.

Fluorescence in situ hybridization (FISH) was developed more than 30 years ago and has been the most paradigm-changing technique in cytogenetic research. FISH has been used to answer questions related to structure, mutation, and evolution of not only individual chromosomes but

This study evaluated fluorescence in situ hybridization (FISH) for rapid identification of Staphylococcus aureus and coagulase-negative staphylococci (CoNS) directly from blood cultures. Initially, 360 blood cultures containing Gram-positive cocci were investigated by a previously described microwave-FISH procedure: 44/49 (89.8 %)

Growing evidence suggests that microbes can influence the efficacy of cancer therapies. By studying colon cancer models, we found that bacteria can metabolize the chemotherapeutic drug gemcitabine (2',2'-difluorodeoxycytidine) into its inactive form, 2',2'-difluorodeoxyuridine. Metabolism was dependent on the expression of
