Error in Qbank or First Aid

[MacGyver]

Qbank says that Haemophilus Influenzae does NOT have IgA protease

First Aid says that it does


Which one is right?

IMHO, I think IgA proteases are associated with all URI bacteria, thats how they colonize mucosal surfaces. So I think First Aid is right, but I'm not sure

Are you implying that there aren't any mistakes/typoes in Q-Bank, or First Aid??????

MWAHAHHAHAHAHA

Don't put words in peoples' mouth, it's annoying. 👎

My understanding is that it does have an IgA protease.

I agree too. I looked it up in my micro text (Sherris Medical Microbiology, 4th ed., Ch.10, p. 166)..."IgA proteases are found in the pathogenic Neisseria, Haemophilus influenzae type b (Hib) ..."

It does. Last time I saw a Hib floating around I looked to make sure.

Lange microbio confirms HiB has IgA protease, as does pneumococcus. There are plenty of URI pathogens w/o IgA protease, and there are non URI pathogens with it. meningococcus has IgA protease too (not a respiratory pathogen). Diptheria and pertussis c. pneumoniae do not have IgA protease.
