Interesting that you ask that ... I've seen both written in different parts of my chart. The pulm doc always says MAI; my ID doc says MAC; my last sputum said MAC. I'm sure I saw MAI on an early sputum. I presumed they were essentially the same.

@janeta MAI comes under the cover of MAC but is a different bug, MAC is gram positive and MAI is gram negitive, It gets very confusing when they call MAI, MAC. Take care Heather

Hi Janeta,

Regarding use of term 'MAI' vs 'MAC', National Jewish Health video link below to Dr. Daley's explanation of the terminology and the various species. Starts at minute 15:40. Basically, 'MAI' is an old term used when they were only aware of 2 species. Since they've discovered that there are actually 12 different species, it has been renamed 'MAC'. I'm guessing that older doctors still use the old term, especially since few of them have much experience in actually treating the condition, let alone keeping up to date with the research.
