[[Aspiration pneumonia]] caused by bacterial infection is the commonest subtype of [[aspiration pneumonia]]. The other subtypes being [[chemical pneumonia]], and airway obstructions.


==Causes==
{{CMG}}; {{AE}} [[Priyamvada Singh|Priyamvada Singh, M.D.]] [mailto:psingh13579@gmail.com]
* Normal flora of upper airways, gingival cavity or stomach.
* Caused by less virulent bacteria, such as anaerobes and aerobic or microaerophilic streptococci


==History and symptoms==
==[[Aspiration pneumonia bacterial infection overview|Overview]]==
===The manifestation depends on:===
* The bacteria involved
* Time since aspiration to diagnosis
* Immune status of the host
===Symptoms in aerobic microbes===
* Indolent course
* Productive [[cough]]
* [[Fever]]
* Absence of [[chills]] and [[rigors]]
* [[Dyspnea]]
* [[Anorexia]], weight loss
* [[Anemia]]
===Symptoms in anaerobic microbes===
Clinical features, which are characteristic of aspiration pneumonia involving anaerobic bacteria, include:


* Indolent course
==[[Aspiration pneumonia bacterial infection pathophysiology|Pathophysiology]]==
* Presence of risk factors: altered sensorium (anesthesia, alcohol, drug, trauma, dysphagia, dental caries)
* Putrid sputum
* Absence of chills and rigors


==Natural History, Complications and Prognosis==
==[[Aspiration pneumonia bacterial infection causes|Causes]]==
* Lung abscess
* Necrotizing pneumonia
* Empyema
* Bronchopleural fistula


==Risk factors==
==[[Aspiration pneumonia bacterial infection differential diagnosis|Differentiating Aspiration pneumonia bacterial infection from other Diseases]]==
* Poor dental hygiene is a risk factor
 
* Patients with good dental hygiene and edentulous are less predisposed
