Veterinary bacteriology: information about important bacteria
|Etymology:||Genus name: bunch of grape-like cocci (coccus means a grain or berry)|
Species epithet: of a dolphin.
|Significance:||[Of minor importance]|
|Type Strain:||Heidy = ATCC 49171 = CCUG 30107 = NCTC 12225.|
|Macromorphology (smell):||The colonies är medium sized (5-7 mm in diameter) and have a hemolysis zone. They are nonpigmented, convexa, glistening and opaque.|
|Micromorphology:||Cocci (0.8-1.0 µm in diameter), which appear singly, in pairs or in clusters.|
|Gram +/Gram -:|
|Other Enzymes:||Coagulase +, urease +.|
|Fermentation of carbohydrates:||
Acid is also produced from fructose and mannose.
|Reservoir:||Mustelidae (e.g. minks, weasels etc.)|
|Disease:||S. delphini has been isolated from aquarium-raised dolphins with skin lesions. The bacterium has also been isolated from horses and is suspected to cause infections.
|16S rRNA Seq.:|
||About 70 species and subspecies have been described within the genus Staphylococcus. S. delphini is closely related to S. pseudintermedius, S. intermedius and S. schleiferi.|
|Comment:||S. delphini can be difficult to differentiate from S. pseudintermedius.|
|New names of bacterial phyla|
The taxonomic category phylum was previously not regulated by the International Code of Nomenclature of Prokaryotes (ICNP), but now this has changed and it was decided to revise the names of bacterial phyla. All phyla must be written in italics (which has been done on VetBact also before) and have the ending -ota.Published 2023-03-01. Read more...
|The taxonomy of chlamydias|
Species within the family Chlamydiaceae were previously divided into two genera Chlamydia and Chlamydophila. However, the differences between these two genera were not that great and many research groups have not accepted this division. Therefore, the genus Chlamydophila has been returned to the genus Chlamydia and this change has now been incorporated in VetBactPublished 2023-03-15. Read more...
