Veterinary bacteriology: information about important bacteria
|Etymology:||Genus name: a thread with a loop.|
Species epithet: killed by heat.
|Significance:||B. thermosphacta is of great concern in the food industry as product (meat) destroyer.
|Alternative Species Name(s):||Microbacterium thermosphactum|
|Type Strain:||ATCC 11509|
|Macromorphology (smell):||Small opaque colonies (0.75-1 mm in diameter). Does not give hemolysis on blood agar.|
|Micromorphology:||Nonmotile rod (0.6-0.75 x 1-2 µm). May form chains (or filaments), which form one or several loops at one end.|

|Other Enzymes:||DNase -, lecithinase -, hippurikase -, tryptophanase -.|
|Biochemical Tests:||Methyl red +, Voges-Proskauer +.|
|Spec. Char.:||Psychrotrophic, optimal growth temperature: 20-25°C, but can grow between 0 and 35°C.|
|16S rRNA Seq.:|
||Two species within the genus Brochothrix have been described.|
|Comment:||Tolerate 10% NaCl and can grow in up to 20% CO2. Not affected by vacuum packing or modified atmosphere.|
|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...
