Veterinary bacteriology: information about important bacteria
|Etymology:||Genus name: named after the German microbiologist Walter Mannheim.|
Species epithet: of different origin (refers to the fact that this species has been isolated from pigs and ruminants).
|Significance:||[Of minor importance]|
|Type Strain:||177 = CCUG 38462|
|Macromorphology (smell):||Small, regular and greyish colonies (1-2 mm in diameter). Most strains give hemolysis on bovine blood agar.|
|Micromorphology:||Non-motile rods or coccoid rods (0.5 x 1.2 µm).|
|Gram +/Gram -:||G-|
|Other Enzymes:||Ornithine decarboxylase (+), tryptophanase -, urease -.|
|Biochemical Tests:||Citrate -, methyl red -, hydrogen sulphide (H2S) -.|
|Fermentation of carbohydrates:||
Other carbohydrates: Adonitol -, dextrin (V), D-fructose +, D-fucose -, D-galactose +, D-glycogen -, mannose -, D-melezitose -, D-melibiose -, D-ribose +, L-sorbose -, xylitol -, D-xylose +.
|Disease:||Pigs: septicemia, enteritis, pneumonia.
Cattle: septicemia, pneumonia, mastitis.
|16S rRNA Seq.:|
||Six 17 have been described within genus Mannheimia. The relationship between members within the closely related genera Actinobacillus, Haemophilus and Pasteurella is very uncertain since none of these genera forms monophyletic clusters.|
|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...
