Fusobacterium spp. - Material Safety Data Sheets (MSDS)

 

MATERIAL SAFETY DATA SHEET - INFECTIOUS SUBSTANCES

SECTION I - INFECTIOUS AGENT

NAME: Fusobacterium spp.

SYNONYM OR CROSS REFERENCE: F. necrophorum, F. mortiferum, F. nucleatum, F. varium, F. gonidiaformans, F alocis, F. pseudonecrophorum, F. salci, F. ulcerans

CHARACTERISTICS: Anaerobic gram-negative bacilli, non-sporulating, slender cells with tapered ends or pleomorphic, irregular staining

SECTION II - HEALTH HAZARD

PATHOGENICITY: Indigenous flora on all mucosal surfaces, normal inhabitants of human cavities (mouth, upper respiratory tract, gastro intestinal tract and urogenital tract); can cause purulent or gangrenous infections; infections involve all regions of body - respiratory, urogenital and gastrointestinal tracts, abscesses, septicemia, pleurisy, necrotizing gingivitis; usually occurring when mucosal damage related to surgery, trauma or disease occurs

EPIDEMIOLOGY: Worldwide; F. nucleatum most common Fusobacterium species found in clinical infections, however, F. necrophorum is most virulent species

HOST RANGE: Humans and animals (horses, cattle, sheep, goats, pigs, fowl and others)

INFECTIOUS DOSE: Not known

MODE OF TRANSMISSION: Part of normal flora that invade tissues after surgical or accidental trauma, edema, anoxia and tissue destruction (from infection with other organisms or malignancies); animal bites; other predisposing factors include antibiotic treatment (eliminate aerobes and foster invasiveness) or immunosuppressive treatment

INCUBATION PERIOD: Not clearly defined

COMMUNICABILITY: Not transmitted from person-to-person

SECTION III - DISSEMINATION

RESERVOIR: Humans and animals (alimentary canal and feces of healthy ruminants and pigs)

ZOONOSIS: Yes - wound contamination by animal bites or feces

VECTORS: None

SECTION IV - VIABILITY

DRUG SUSCEPTIBILITY: Sensitive to penicillin, clindamycin, chloramphenicol

DRUG RESISTANCE: Erythromycin and macrolides

SUSCEPTIBILITY TO DISINFECTANTS: Susceptible to disinfectants - 1% sodium hypochlorite, 70% ethanol, 2% glutaraldehyde, iodines, phenolics, formaldehyde

PHYSICAL INACTIVATION: Sensitive to moist heat (121° C for at least 15 min) an dry heat (160-170° C for at least 1 hour)

SURVIVAL OUTSIDE HOST: Manure - 292 days; culture exposed to air -7 days; soil - 56 days

SECTION V - MEDICAL

SURVEILLANCE: Presence of foul-smelling discharge or gas in tissue suggests infection, microscopic examination, GLC and molecular probes

FIRST AID/TREATMENT: Surgical drainage, alone or together with antibacterial therapy

IMMUNIZATION: None

PROPHYLAXIS: Preventive treatment with penicillin

SECTION VI - LABORATORY HAZARDS

LABORATORY-ACQUIRED INFECTIONS: 1 reported Fusobacterium infection

SOURCES/SPECIMENS: Feces, wound exudates, necrotic tissues, respiratory and urogenital specimens

PRIMARY HAZARDS: Accidental parenteral inoculation; direct contact of mucous membranes (or wound, cuts on skin)

SPECIAL HAZARDS: None

SECTION VII - RECOMMENDED PRECAUTIONS

CONTAINMENT REQUIREMENTS: Biosafety level 2 practices, containment equipment and facilities for activities involving infectious specimens and cultures of F. necrophorus

PROTECTIVE CLOTHING: Laboratory coat; gloves when direct contact with infectious materials is unavoidable

OTHER PRECAUTIONS: None

SECTION VIII - HANDLING INFORMATION

SPILLS: Allow aerosols to settle; wearing protective clothing, gently cover spill with paper towel and apply 1% sodium hypochlorite, starting at perimeter and working towards the centre; allow sufficient contact time (30 min) before clean up

DISPOSAL: Decontaminate before disposal; steam sterilization, chemical disinfection, incineration

STORAGE: In sealed containers that are appropriately labelled
