Treponema spp. in Porcine Skin Ulcers
... challenge study was performed to test if Treponema pedis induced skin lesions.
Serological response towards TPE0673, a T. pedis protein, was tested with ELISA.
Spirochetes were found in all types of skin ulcers and in all herds. The occurrence of
Treponema spp. detected by PCR was 52% in shoulder ul ...
Epiphytic Planctomycetes from macroalgae
... Marine macroalgae are widely colonized by a variety of macro and micro-organisms
like invertebrates, diatoms, fungi and bacteria. Of these, the association bacteriamacroalgae is the one most studied and it has been described for over a century.
Research in this area has mainly been focused on reprod ...

Bacterial taxonomy is the taxonomy, i.e. the rank-based classification, of bacteria.In the scientific classification established by Carl von Linné, each species has to be assigned to a genus (binary nomenclature), which in turn is a lower level of a hierarchy of ranks (family, suborder, order, subclass, class, division/phyla, kingdom and domain).In the currently accepted classification of Life, there are three domains (Eukaryotes, Bacteria and Archaea), which, in terms of taxonomy, despite following the same principles have several different conventions between them and between their subdivisions as are studied by different disciplines (Botany, zoology, mycology and microbiology), for example in zoology there are type specimens, whereas in microbiology there are type strains.
