Por ello, se admite que la confirmacion diagnostica puede plantearse por la deteccion de una masa purulenta bacteriana, la confirmacion de una masa purulenta por histologia, o la positividad de un cultivo para Actinomyces
Nocardia infection occasionally presents as a mass lesion, and FNA reveals a nonspecific suppurative background and slender filaments that branch at right angles, in contrast to the acute angle branching of Actinomyces
She was suspected of having a mixed infection with Actinomyces
species based on the pathological findings.
These bacteriostatic actions above may have the same effect in Streptococcus mutans, Actinomyces
viscosus, Lactobacillus and Streptococcus sanguis.
neuii is aerobic and catalase positive member of this family.

Peptoniphilus grossensis (18 cases) and Actinomyces
ihuae (17 cases) were the most commonly isolated bacteria (Table 1).
colonization of tonsils: a comparative study between patients with and without recurrent tonsillitis.
These included Propionibacterium propionicus, Corynebacterium amycolatum, Actinomyces
massiliensis, and Bacteroides thetaiotaomicron, reported Teri M.
Subjects with higher alcohol consumption had certain genera that were enriched, including Actinomyces
, Leptotrichia, Cardiobacterium, and Neisseria; some of these genera contain oral pathogens, and Neisseria can synthesize alcetaldehyde from ethanol.

Empiric antibiotic choice for a pyogenic abscess should be directed at the microbes typically responsible, which include aerobic enteric Gram-negative bacilli (Escherichia coli and Klebsiella pneumoniae, the latter particularly prevalent in Asia), Gram-positive cocci (most commonly the Streptococcus milleri group but also including Staphylococcus aureus, Streptococcus pyogenes, and Enterococcus spp.), and anaerobes (Bacteriodes, Fusobacterium, Actinomyces
, and anaerobic streptococci) [10, 11].
Fusobacterium, Porphyromonas, Prevotella, Parvimonas, Tannerella, Treponema, Dialister, Filifactor, Actinomyces
, Olsenella, and Pseudoramibacter predominated in the canals.
The differential diagnosis of primary spondylodiscitis includes mycobacteria; pyogenic and fungal infections due to Staphylococcus aureus, Cryptococcus spp., and Actinomyces
spp.; other granulomatous diseases such as sarcoidosis and brucellosis; and tumors (metastasis, myeloma, lymphoma).
