Bacteria
Bacillus subtilis (Ehrenberg 1835) Cohn 1872
Strain/Type
Bacillus subtilis strain 168
Bacillus subtilis strain DSM10
Host tropism
Route of Transmission
Transmission does not occur.
Zoonosis (transmission between animals and humans): No
Characteristics e.g. sensitizing or toxic effects, resistance to antibiotics
Pathogenicity:
Biological agents that are unlikely to cause human disease.
Note +:
Identified as or suspected of being pathogens in individual cases, mainly in individuals with considerably reduced immunity; identification of the type is often not reliable.
Allergenicity
An allergic / sensitising potential is not known.
B. subtilis produces the extracellular enzyme subtilisin, which has been reported to cause allergic or hypersensitivity reactions in individuals after repeated exposure (e.g. in industrial processes).
Sporulation
Forms spores.
Bacillus subtilis forms heat- and acid-resistant endospores.
Resistances
B. subtilis endospores are highly resistant to harmful environmental factors and common non-sporicidal disinfectants.
Some strains of B. subtilis have been observed to be resistant to different classes of antibiotics.
Approved as biological safety measure if taken as recipient organism for genetic engineering?
Genetically modified (GenTSV)
Risk group (BioStoffV)

Occupational health care (according to ArbMedVV)
Optional health care:
In the case of activities with the biological agent no health care is required. An indication on restrictions for immunosuppressed workers should be made.
Vaccination:
Vaccination is not necessary, and a vaccine is not available.
