Both: It can be due to either or. Most cases of infectious bronchitis are due to viruses though, and will not respond to antibiotics.

Depends: Bronchitis is an inflammatory condition of the bronchial tubes. It can be broken down to infectious or non-infectious. Infectious causes include bacterial, viral and rarely fungal. Most commonly in an otherwise health adult, most bronchitis is viral (i.e. Untreatable with antibiotics.) non-infectious causes include allergens (pollens, molds, etc.) and irritants (smoke, chemicals, etc.).
Dr. Sue Ferranti

Either...: Acute bronchitis could be due to either a bacterial or viral infection whereas chronic bronchitis, a form of copd, is due to smoking.

What are the causes of ear infections?

Dr. Anatoly Belilovsky

Ears are connected..: ...To the nose on the inside, with a tunnel called the eustacian tube. Anything that happens in the nose, can affect the ear.
Dr. Brian Affleck
ENT and Head and Neck Surgery 30 years experience
The most common cause of ear infection is that the Eustachian tube isn't working. This results in a negative pressure, like a small vacuum. The negative pressure can be strong enough to pull fluid from the delicate tissues lining the middle ear. Once there is fluid, bacteria from the nose can then infect it. There are several reasons for the Eustachian tube to not work, including colds/allergy

What can I do to prevent bacterial infections?

Good hygiene: The best way to prevent bacterial infections, or viral infections, is good hygiene. Wash your hand properly and often. Next come nutrition; your immune system works much better if you give it the proper tools to work with. Next comes sleep; not sleeping properly or enough has been shown to weaken the immune system and increase susceptibility to infections.

Possibly pneumonia: I have found that when people have a deep cough associated with pain on taking a deep breath they often times have pneumonia. You should be evaluated by a physician. If this has been a long-term problem then you definitely need to be evaluated as there are other causes.
