Shigeyuki Hamada mostly deals with Microbiology, Streptococcus mutans, Porphyromonas gingivalis, Fimbria and Molecular biology. As a part of the same scientific family, he mostly works in the field of Microbiology, focusing on Treponema denticola and, on occasion, Prevotella nigrescens, Bacteroides and Eikenella corrodens. The concepts of his Streptococcus mutans study are interwoven with issues in Glucosyltransferase, Enzyme, Serotype and Antibacterial activity.
In his study, which falls under the umbrella issue of Porphyromonas gingivalis, Fimbriae Proteins and Monocyte is strongly linked to Peptide. Shigeyuki Hamada interconnects Inflammation, Dental plaque, Bacteroidaceae, Immunoglobulin A and Mucous membrane of nose in the investigation of issues within Fimbria. Shigeyuki Hamada focuses mostly in the field of Molecular biology, narrowing it down to topics relating to Southern blot and, in certain cases, Molecular cloning, Antigen Gene, Plasmid, Mutant and Structural gene.
His main research concerns Microbiology, Streptococcus mutans, Biochemistry, Serotype and Molecular biology. Many of his research projects under Microbiology are closely connected to Strain with Strain, tying the diverse disciplines of science together. His research integrates issues of Glucosyltransferase, Glucosyltransferases, Enzyme and Glucan in his study of Streptococcus mutans.
In his research on the topic of Glucan, Dextranase is strongly related with Polysaccharide. His research investigates the connection between Serotype and topics such as Antigen that intersect with problems in Antibody and Immune system. As part of the same scientific family, Shigeyuki Hamada usually focuses on Molecular biology, concentrating on Porphyromonas gingivalis and intersecting with Peptide.
Shigeyuki Hamada mainly focuses on Microbiology, Enterobacteriaceae, Plasmid, Genetics and Gene. His Microbiology research focuses on Drug resistance in particular. His research in Enterobacteriaceae intersects with topics in Klebsiella pneumoniae, Colistin and Meropenem.
His Plasmid research incorporates elements of Carbapenem-resistant enterobacteriaceae and Pulsed-field gel electrophoresis. His work deals with themes such as Immunology, Pathogenesis, Immunoglobulin class switching, Germinal center and Streptococcus, which intersect with Streptococcus pyogenes. His research in Streptococcus focuses on subjects like Intergenic spacer, which are connected to Serotype.
His primary areas of investigation include Microbiology, Enterobacteriaceae, Gene, Bacteria and Escherichia coli. His Microbiology research is multidisciplinary, relying on both Multilocus sequence typing and Streptococcus suis serotype. His Streptococcus suis serotype research is multidisciplinary, incorporating perspectives in Meningitis, Bioinformatics, Virology, Sepsis and Rare case.
The Enterobacteriaceae study which covers Plasmid that intersects with Colistin. His study on Multiplex polymerase chain reaction, Bacterial protein, genomic DNA and Pcr cloning is often connected to Dipstick as part of broader study in Gene. His studies deal with areas such as Typing and Mobile genetic elements as well as Bacteria.
