Which type of prostatitis is caused specifically by bacterial infection?

Acute prostatitis is characterized specifically by a bacterial infection of the prostate gland. This condition can develop suddenly and typically presents with inflamed prostate tissue, often accompanied by severe symptoms such as fever, chills, pelvic pain, and urinary difficulties. The underlying cause is usually a bacterial pathogen, which can lead to significant discomfort and requires prompt medical treatment, often with antibiotics.

Chronic prostatitis, while it can also have a bacterial component, is generally more complex and can involve persistent symptoms that aren't necessarily linked to active bacterial infection. Non-bacterial prostatitis refers to conditions where no bacterial infection is present, such as inflammatory or pain syndromes without identifiable pathogens. Asymptomatic prostatitis, on the other hand, is defined by the absence of noticeable symptoms, although inflammation may still be present. Thus, acute prostatitis distinctly stands out as directly caused by a bacterial infection, making it the correct choice.
