CHARACTERISTICS: Gram-positive large rods, non-spore forming, anaerobic or microaerophilic, occur singly or in pairs
SECTION II – HEALTH HAZARD
PATHOGENICITY: Very rarely pathogenic; part of normal flora in man and animals (mouth, vagina, and intestinal tract); in the oral cavity, associated with dental caries but no known etiologic role; have been reported to cause endocarditis, neonatal meningitis and bacteremia
EPIDEMIOLOGY: Worldwide
HOST RANGE: Normal flora of humans and animals
INFECTIOUS DOSE: Not known
MODE OF TRANSMISSION: Not known
INCUBATION PERIOD: Not known
COMMUNICABILITY: Not transmitted from person-to-person
SECTION III – DISSEMINATION
RESERVOIR: Widespread in nature, humans and animals
ZOONOSIS: None
VECTORS: None
SECTION IV – VIABILITY
DRUG SUSCEPTIBILITY: Susceptible to antibiotics
DRUG RESISTANCE: vancomycin-resistant strains have been isolated
SUSCEPTIBILITY TO DISINFECTANTS: Susceptible to many disinfectants – 1% sodium hypochlorite and 70% ethanol, glutaraldehyde, formaldehyde, iodines
PHYSICAL INACTIVATION: Susceptible to moist heat (121° C for at least 15 min) and dry heat (160-170° C for at least 1 hour)
SURVIVAL OUTSIDE HOST: Feces – 2 days; cheese – 105 years;
SECTION V – MEDICAL
SURVEILLANCE: None
FIRST AID/TREATMENT: Wash area in contact with warm water and soap (omit soap for mucous membrane exposure); drug therapy (penicillin and aminoglycosides)
IMMUNIZATION: None
PROPHYLAXIS: None
SECTION VI – LABORATORY HAZARDS
LABORATORY-ACQUIRED INFECTIONS: No reported cases of laboratory infections with Lactobacillus spp.
SOURCES/SPECIMENS: Dairy products and other food, feces, specimens from the mouth, vaginal swabs
PRIMARY HAZARDS: Hazard of infection from this organism is low, however, it is prudent to avoid accidental inoculation and ingestion
SPECIAL HAZARDS: None
SECTION VII – RECOMMENDED PRECAUTIONS
CONTAINMENT REQUIREMENTS: No special design features beyond those suitable for a well designed and functional laboratory with good microbiology practices; this level of containment does not allow for any additional risk that may present for those persons with pre-existing disease, compromised immunity or who are pregnant
PROTECTIVE CLOTHING: Laboratory coat; gloves when contact with infected material is unavoidable
OTHER PRECAUTIONS: None
SECTION VIII – HANDLING INFORMATION
SPILLS: Allow aerosols to settle; wearing protective clothing, gently cover spill with absorbent 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
STORAGE: In sealed containers that are appropriately labelled
