Which organism is known for causing respiratory infections associated with poor dental hygiene?

The organism associated with respiratory infections linked to poor dental hygiene is diverse and includes multiple types. Kingella, Actinobacillus, and Eikenella all belong to a group of bacteria that are part of the normal flora of the oral cavity and can be implicated in respiratory diseases, particularly in individuals with underlying conditions or poor dental hygiene.

Kingella, a genus of bacteria, can cause infections particularly in children, often following dental procedures or in cases where there is periodontal disease. This involves the respiratory system and can lead to various complications.

Actinobacillus, particularly Actinobacillus actinomycetemcomitans, has also been associated with periodontitis and can be involved in respiratory infections as it enters the system through the oral cavity.

Eikenella corrodens, which is frequently found in the mouth, can also lead to infections that may manifest in the respiratory system if the bacteria are aspirated or if there are other routes of entry due to poor dental hygiene.

Given that all three organisms are linked to respiratory infections in the context of poor dental hygiene, stating that "all of the above" contributes to these infections accurately reflects the association of each of these organisms within this clinical context.
