Veterinary bacteriology: information about important bacteria
|Etymology:||Genus name: named after the Swiss ophthalmologist V. Morax. |
Species epithet: from Oslo.
|Significance:||Is not important in veterinary medicine.
[Of minor importance]
|Type Strain:||A1920 = ATCC 19976 = CCUG 350 = NCTC 10465.|
|Macromorphology (smell):||Forms small semiopaque colinies in 48 h (2-2.5 mm in diameter). No hemolysis on blood agar.|
|Gram +/Gram -:||G-|
|Other Enzymes:||DNase -, tryptophanase (indole) -|
|Fermentation of carbohydrates:||Members of the genusMoraxella do not ferment carbohydrates.|
|Vector:||The nematode Phasmarhabditis hermaphrodita and M. osloensis are mutualistic symbionts.|
|Clinical Picture:||The infected slugs die in 4-10 days.|
|Virulence Factors:||The lipopolysaccharide (LPS) of M. osloensis, which is an endotoxin that is lethal to certain slugs.|
|16S rRNA Seq.:|
||About 20 species have been described within genus Moraxella and these species are related to members of the genus Acinetobacter.|
|Comment:||Is used for biological contol of slugs, particularly the grey field slug (Deroceras reticulatum) and Spanish slug (Arion vulgaris). The commersial product NemaSlug contains nematodes, which have been colonized in the gut by M. osloensis.|
|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...
