Gemella haemolysans - Material Safety Data Sheets (MSDS)

 

MATERIAL SAFETY DATA SHEET - INFECTIOUS SUBSTANCES

SECTION I - INFECTIOUS AGENT

NAME: Gemella haemolysans

SYNONYM OR CROSS REFERENCE: N/A

CHARACTERISTICS: Gram positive cocci; however they are easily decolorized and may appear gram negative or gram variable; occurs as diplococci with adjacent sides flattened (resembles those of neisseria); aerobic or facultatively anaerobic

SECTION II - HEALTH HAZARD

PATHOGENICITY: Normal flora of oral cavity or upper respiratory tract; low virulence, opportunistic agent for compromised hosts isolated from bronchial secretions and human gingiva; infection often occurs in previously damaged tissue - endocarditis; septic shock, meningitis, arthritis and pneumonia

EPIDEMIOLOGY: Worldwide occurrence

HOST RANGE: Humans; mammals

INFECTIOUS DOSE: Unknown

MODE OF TRANSMISSION: Unknown

INCUBATION PERIOD: Unknown

COMMUNICABILITY: Not transmitted from person-to-person

SECTION III - DISSEMINATION

RESERVOIR: Many species of mammals

ZOONOSIS: None

VECTORS: None

SECTION IV - VIABILITY

DRUG SUSCEPTIBILITY: Sensitive to penicillin, streptomycin, tetrasulfathiazole, chloramphenicol, vancomycin

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

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: Does not survive well outside of host

SECTION V - MEDICAL

SURVEILLANCE: Monitor for symptoms; immunological techniques not available

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

IMMUNIZATION: None

PROPHYLAXIS: Not usually administered

SECTION VI - LABORATORY HAZARDS

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

SOURCES/SPECIMENS: Bronchial specimens; mucous membranes, blood, cerebrospinal fluid, urine or wound specimens

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

SPECIAL HAZARDS: None

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 present for those persons with pre-existing disease, compromised immunity or who are pregnant

PROTECTIVE CLOTHING: Laboratory coat; gloves when 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 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
