Fig 1.  Jaw abscess aspirate, smear, Gram stain, light
microscopy, LPV. Purulence, heavy. Granules present.
Suspicious for Actinomyces (see Fig 2).

Fig 2.  Jaw abscess aspirate, smear, Gram stain, light
microscopy, HPV. Purulence, heavy. Gram-positive bacilli,
filamentous, beaded, branched, partial acid-fast stain
negative. Morphology consistent with Actinomyces spp.
Impression: actinomycosis (lumpy jaw).

Fig 3.  Cutaneous sinus tract aspirate, smear, Gram
stain, light microscopy, HPV. Purulence, heavy. Gram-positive
bacilli, filamentous, beaded, branched, partial acid-fast stain
negative. Morphology consistent with Actinomyces spp.
(see Plate 39). Impression: actinomycosis.

Fig 4.  Cutaneous sinus tract aspirate, colonies on
anaerobic blood agar plate. Mixed colony morphotypes.
Molar tooth colonies. Morphology consistent with
Actinomyces israelii. Impression: mixed anaerobic infection:
actinomycosis.

Fig 5.  Expectorated sputum, smear, Gram stain, light
microscopy, HPV. Purulence, heavy. Local materials,
moderate. Grain present. Gram-positive bacilli, filamentous,
beaded, branched. Suspicious for Nocardia or Actinomyces
(see Fig 6).

Fig 6.  Expectorated sputum, chalky white colonies on
plate with 5% sheep’s blood agar at 5 days’ incubation.
Routine sputum culture. Morphology consistent with
Nocardia, Nocardiopsis, or Streptomyces spp

Fig 7.  Sinus-tract granule, crush-pull smear, Gram stain,
light microscopy, HPV. Amorphous debris, moderate.
Gram-positive bacilli, filamentous, beaded, branched, partial
acid-fast negative. Gram-positive bacilli, regular. Gramnegative bacilli, small.
Gram-positive cocci. Morphology
suggests mixed anaerobic infection with actinomycetes.
Impression: actinomycosis. Culture isolation of Actinomyces
naeslundii.

Fig 8.  Surgical biopsy of abnormal area in jawbone,
smear, Gram stain, light microscopy, HPV. Amorphous debris,
heavy. Gram-positive bacilli, filamentous, beaded, branched,
partial acid-fast stain negative. Morphology suggests
actinomycete. Aerobic and anaerobic cultures negative.
