This disease's causative 
This disease's causative agent uses its DrrA protein to hijack Rab1 activity, and uses SidK to inhibit an H+-ATPase. The bacteria that causes this disease has one of the only known type IVB or icm/dot secretory systems, which it uses to secrete LidA and Ank-related proteins into a vacuole, and it is diagnostically grown on charcoal extract agar with cysteine. Assaying for its serogroup 1 antigen in urine is a common diagnostic method, and that test is positive even after initiating treatment. The bacterium that causes this disease commonly infests A castellani, and is related to the organism that causes Pontiac fever. This disease is caused by a non-fermenting, non-capsulated gram-negative (*) rod that infests macrophages. The causative agent of this deadly pneumonia commonly grows in cold water tanks. For 10 points, name this disease named for the fact that the first outbreak occurred at a Philadelphia meeting of a certain veteran's organization.
