JVD 2019 #2 Microbiological Aspects of Naturally Occurring Primary Endodontic Infections in Dogs; Srecnik Flashcards
What association was found between the number of bacterial species in root canal infection & clinical or radiographic signs of endo dz
No statistically significant assoc was found.
What were the most frequently identified bacteria genera?
What is it for humans?
Pasteurella, Bacteroids, and Propionibacterium ( 30 diff species from 16 genera found overall)
These are considered opportunistic pathogens and have all been prev recovered from subgingival plaque in dogs.
Humans= Proteobacteria, Bacteroides & Actinobacteria
Was the number of bacterial species in root canals higher or lower with fracture longer than 12 mo?
Significantly lower when the duration of the fracture was greater than 12 mo.
Of the 28 bacterial isolates, how many were Gram Positive or Gram Negative?
46% Gram +
54% Gram -
