    • OTHER BACTERIA
      • LISTERIA MONOCYTOGENES
      • ERYSIPELOTHRIX RHUSIOPATHIAE
      • ALCALIGENES FAECALIS
      • CHROMOBACTERIUM VIOLACEUM
      • FLAVOBACTERIUM MENINGOSEPTICUM
      • GARDENERALLA VAGINALIS
      • DONOVANIA GRANULOMATIS
      • ACINETOBACTER
      • STREPTOBACILLUS MONILIFORMIS
      • SPIRILLUM MINUS
      • LEGIONELLA PNUEMOPHILIA
    • Listeria monocytogenes
      • Gram + bacilli
      • Tumbling motility at 25C,nonmotile at 37C
      • Saprophyte on soil ,water, sewage.
      • Meningitis in neonates,elderly
      • Abcess, conjunctivitis,pharyngitis,urithritis
      • Anton Test -instillation into eyes of rabbits-Keratoconjunctivitis
      • Isolation-vaginal secr.,lochia,meconium,cord blood,csf,blood.
      • Cold enrichment -materials stored in tryptose phosphate/thioglycolate broth at 4C,and subculture are done at weekly intervals forn 1-6 months
      • Isolates may be missed as diphtheroids
      • Treatment
      • Ampicillin
      • Cotremoxazole
      • Gentamycin
    • Erysipelothrix rhusiopathiae
      • Gram + bacilli-nonmotile
      • Cause swine erysipelas,human eryseipeloid
      • Human infections in hands or fingers of persons handling animals,fish
      • Lesions are edematous,painful erythema
      • Treatment
      • Penicillin
      • Erythromycin
    • Alcaligenes faecalis
      • Gram –ve bacilli—motile
      • Saprophyte
      • Cause
      • Typhoid like fever
      • UTI
      • Infentile gastro enteritis
    • Chromobacterium violaceum
      • Gram –ve bacilli-motile
      • Violet coloured pigment
      • Skin lesions with pyemia and multiple abcess
    • Flavobacterium meningosepticum
      • Gram-ve bacilli---nonmotile
      • Yellow pigment
      • Meningitis in newborns
    • Gardenerella vaginalis
      • Gram-ve bacilli- nonmotile
      • Causes Bacterial vaginosis charecterised by-
      • Raised vaginal PH(>4.5)
      • Foul smelling discharge
      • Clue cells
      • BV also by Mobilincus and bacteroids
      • Clue cells –vaginal epithelial cells studded with numerous bacteria
      • Treatment Metronidazole
    • Donovania granulomatis
      • Gram –ve bacilli---nonmotile
      • Bipolar condensation of chromatin-closed safty pin appearance
      • Causes Donovanosis-painful papule on the genitalia
      • Treatment
      • Tetracyclin
      • Cotrimoxazole
      • Chloramphenicol
      • Gentamycin
    • Acinetobacter
      • Gram –ve bacilli ---nonmotile
      • A.baumanni-pink colour on MA
      • A.Lowffi-yellow colour on MA
      • Iatrogenic meningitis
    • Rat bite Fever
      • Caused by streptobacillus moniliformis(gram-ve nonmotile) and spirillnum minus(g-ve bacillus –motile)
      • Rat bite may have healed-but it suppurates with fever and regional lymphadenopathy
      • Both types responds to
      • Penicilline
      • Tetracycline
    • Legionella pneumophilia
      • Gram –ve bacilli –motile
      • Stains better with silver impregnation method
      • Best visualised by direct immunofluroscent antibody stain with monoclonal /polyclonal sera
      • Human infection –inhalation of aerosoles produced by cooling towers-AC,cause legionellosis
      • Legionnaire’s d/sfever ,nonproductive cough,dyspnoea,leading to pneumonia
      • Pontaic fever –nonfatal influenza like d/s.
      • Treatment
      • Macrolides
      • Ciprofloxacin
      • Tetracycline
    • Nonsporing anerobes
    • Classification
      • Cocci
      • Bacilli
      • Spirochetes
