CHARACTERISTICS: Gram negative short rods, aerobic, non-motile, asaccharolytic coccobacilli, occurring in pairs and short chains
PATHOGENICITY: Parasitic on human skin, mucous membranes; invasion of the mucous membranes causes respiratory disease; occular pathogen (4th most common source of corneal infections); other complications include otitis media, endophthalmitis, bacteremia, septic arthritis, pneumonia, purulent pericarditis, meningitis
EPIDEMIOLOGY: Worldwide, especially in persons living under poor hygienic conditions where organism is easily spread (eg. conjunctivitis)
HOST RANGE: Humans, other mammals
INFECTIOUS DOSE: Not known
MODE OF TRANSMISSION: Direct contact of mucous membranes with infectious agent; opportunistic pathogen found as a normal inhabitant but may be a secondary invader in the respiratory tract
INCUBATION PERIOD: Not clearly defined
COMMUNICABILITY: Not usually transmitted from person-to-person
RESERVOIR: Upper respiratory tract of mammals
ZOONOSIS: None
VECTORS: None
DRUG SUSCEPTIBILITY: Sensitive to penicillins, cephalosporins, tetracyclines, quinolones, aminoglycosides
DRUG RESISTANCE: 85 - 100% of the isolates are resistant to ampicillin and amoxicillin
SUSCEPTIBILITY TO DISINFECTANTS: Susceptible to many disinfectants - 1% sodium hypochlorite, 70% ethanol, 2% glutaraldehyde, iodines, phenolics, 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: Glass - 3 days; insects - 4 days
SURVEILLANCE: None
FIRST AID/TREATMENT: Antibiotic therapy
IMMUNIZATION: None
PROPHYLAXIS: Not usually administered
LABORATORY-ACQUIRED INFECTIONS: No infections reported to date
SOURCES/SPECIMENS: Respiratory specimens, throat swabs, sputum
PRIMARY HAZARDS: Direct contact of mucous membranes with infectious materials; accidental parenteral inoculation; inhalation of infectious droplets
SPECIAL HAZARDS: None
CONTAINMENT REQUIREMENTS: Biosafety level 2 practices, containment equipment and facilities for all activities involving known or potentially infectious specimens and cultures
PROTECTIVE CLOTHING: Laboratory coat; gloves when direct contact with infectious materials is unavoidable
OTHER PRECAUTIONS: Good personal hygiene and frequent hand washing (avoid rubbing eyes)
SPILLS: Allow aerosols to settle; wearing protective clothing, gently cover spill with paper towels 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
