How commonly does pseudomonas aeruginosa infect the lungs?

It occurs, And can be life-threatening but in my experience most of the time that the organism is isolated from respiratory cultures in hospitalized patients, it is a colonizer, not the cause of pneumonia.
Common in the ICU. It is not common to get this infection in a normal host, that is someone who is healthy otherwise. This kind of pneumonia is fairly common in patients who become very ill from some other problem are require support in the intensive care unit, who otherwise have weakened immune systems, or who have cystic fibrosis which is a genetic disease, involving abnormally thick mucous in the lung.

Can monobactams work to treat pseudomonas aeruginosa?

Maybe. Monobactams are drugs chemically similar to the penicillins. The only commercially available monobactam in the United States is a drug called aztreonam, it is effective against some strains of pseudomonas but not all. Because of this it is more of a second choice agent in those who can not take drugs that have greater efficacy because of allergies etc. Read more...

Can cephalosporins work to treat pseudomonas aeruginosa?

Sometimes. There are several kinds or "generations" of cephalosporins antibiotics, which are antibiotics that are chemically related to penicillin. Some of the drugs in this class are highly effective against pseudomonas and some are not.
