Granules_Aggregatibacter actinomycetemcomitans

  • General

    • In liquid media, the colonies form granules that adhere to the side of the tube.

      Aggregatibacter actinomycetemcomitans is a gram-negative, fastidious, coccoid or rod-shaped bacillus.
      It can grow aerobically, and capnophilic.
      In culture, Aggregatibacter actinomycetemcomitans produces small colonies (0.5-3.0 mm in diameter) after about 38-72 hours of incubation on blood agar, with subsequent growth into a star-like structure with pitting of the agar medium.

  • History

    • Fear of the dentist is one of the most common fobhias.

      Until the mid-18th century, perhaps the main providers of dental services were barber-surgeons.
      Before they split to form seperate companies in 1745, barbers and surgeons were effectively one entity and were responsible for a range of services relating to care of the body. Such as patching up wounds, tending broken limbs, letting blood and also pulling teeth, as well as barbering roles like cutting hare and shaving.
      Barber-surgeons were ubiquitous across the country and could be found even in small towns and villages.

      What would it have been like to have a tooth pulled before anaesthetic?
