NAME: Aerococcus spp.
SYNONYM OR CROSS REFERENCE: A. viridans, A. urinae, A. christensenii
CHARACTERISTICS: Gram positive cocci, usually singly or in tetrads; microaerophilic
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
RESERVOIR: Widespread in nature; aquatic and marine environments; common airborne organism in hospitals; can also be found on human skin
ZOONOSIS: None
VECTORS: None
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
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
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
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
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
