Aerococcus spp.

MATERIAL SAFETY DATA SHEET - INFECTIOUS SUBSTANCES

SECTION I - INFECTIOUS AGENT

NAME: Aerococcus spp.

SYNONYM OR CROSS REFERENCE: A. viridans, A. urinae, A. christensenii

CHARACTERISTICS: Gram positive cocci, usually singly or in tetrads; microaerophilic

SECTION II - HEALTH HAZARD

PATHOGENICITY: Opportunistic pathogen; associated with bacteremia, endocarditis and urinary tract infections ; primary cause of fatal lobster disease called gaffkemia; causes greenish discolouration of pickled and cooked meats, such as ham products

EPIDEMIOLOGY: Occurs worldwide

HOST RANGE: Lobsters, humans

INFECTIOUS DOSE: Unknown

MODE OF TRANSMISSION: Opportunistic pathogen causing infections as a result of trauma, or in immune compromised individuals

INCUBATION PERIOD: Unknown

COMMUNICABILITY: Not directly transmitted from person to person

SECTION III - DISSEMINATION

RESERVOIR: Widespread in nature; aquatic and marine environments; common airborne organism in hospitals; can also be found on human skin

ZOONOSIS: None

VECTORS: None

SECTION IV - VIABILITY

DRUG SUSCEPTIBILITY: Penicillin, vancomycin, macrolides, tetracyclines, chloramphenicol

DRUG RESISTANCE: A. viridans displays a low level of resistance to aminoglycosides; penicillin resistance has been reported in 1 case; A. urinae is resistant to sulfonamides

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

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

SURVIVAL OUTSIDE HOST: Survives well in nature - soil, marine environments

SECTION V - MEDICAL

SURVEILLANCE: None

FIRST AID/TREATMENT: Wash exposed area with soap and warm water (omit soap if mucous membrane exposure); antibiotic therapy

IMMUNIZATION: None

PROPHYLAXIS: None

SECTION VI - LABORATORY HAZARDS

LABORATORY-ACQUIRED INFECTIONS: No reported cases of laboratory infection with Aerococcus spp.

SOURCES/SPECIMENS: Environmental sources - soil, water; blood, wound exudates, endometrium

PRIMARY HAZARDS: Hazard of infection is low, however, avoid accidental parenteral inoculation, ingestion, and inhalation of infectious droplets

SPECIAL HAZARDS: No special hazards

SECTION VII - RECOMMENDED PRECAUTIONS

CONTAINMENT REQUIREMENTS: Well designed laboratory with good microbiological techniques; this level of containment does not allow for any additional risk that may be present for persons with pre-existing disease, compromised immunity, or who are pregnant

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 absorbent paper towel and apply 1% sodium hypochlorite, starting at the 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
