I am immuno-compromised, am I more likely to get pseudomonas aeruginosa?

Possibly. Ps. Aeruginosa infections are most commonly acquired in the hospital setting. They are very common in cystic fibrosis patients. Some compromise in the host health status underlies most of the serious problems with ps. Aer. Infections. Main host factors that affect risk are low white blood cell count, burn wounds or other disruption of skin or mucosal surfaces.
Yes. Yes you are. It is an opportunistic infection that is more prevalent in people with immunodeficiencies/suppression.

My child has asthma are they more likely to get pseudomonas aeruginosa?

No. Individuals with asthma are not at any higher risk to develop pseudomonas infection than general population. Exception would be when they develop a respiratory failure requiring ventilator support and ICU stay.
No. There is no known association between asthma and pseudomonas aeruginosa infections per se. Patients on high dose steroids who are hospitalized may be less able to fight off the infection - but there are no reported associations even in this extreme case.
No. Asthma does not predispose a person to a bateria such as pseudomonas. Very unlikely.

My child as cystic fibrosis, how likely will he get pseudomonas aeruginosa?

Later in life. Patients with cystic fibrosis often get these bacteria in their airways by adulthood. The vast majority of adult CF patients have airways colonized with pseudomonas aeruginosa (pa). Younger patients (kids) tend not to have pa in their airways, but that can vary.
Unlikely as a child. Pseudomonas aeruginosa is a bacterium that typically infects patients with CF in the second or third decade in life - the longer someone with CF lives the higher the odds of getting pseudomonas are. Additionally, the worse the patient's lung function is the higher the odds of getting p. Aeruginosa are. Not everyone with CF will get it during their lifetime - but most do (at this time).
CF registry. The CF registry has specific data to answer this question. The overall percentage of patients with p. Aeruginosa in 2006 was 55%, and by the age of 11 years, about 60% of patients will be colonized. I hope this helps.

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. In fact this can vary to some degree depending on the antibiotic sensitivities specific to the pseudomonas strains prevalent in a particular hospital or community.
Yes some. There are many different cephalosporin antibiotics. Many are not effective against ps. Aer. Those that are active against this organism are Fortaz (ceftazidime) and maxipime (cefepime).
