No with precautions: Could be if contaminated, the bacteria will not survive out side body, effusion is mostly a reaction to infection.

Yes: The tuberculosis bacteria is only rarely found in the pleural effusion, so it makes diagnosis difficult; however, if it is seen, it is just as infectious as from any other source. The main question is whether the patient is expelling tuberculosis from his respiratory tract as well, because 1/3 of patients with pleural effusion TB will have it in their lungs as well.

No: Only pulmonary TB is infectious; pleural TB is not.
