 The bacterial test is now non-repeatable because the parts were subsequently taken out of quarantine and fully re-exposed to terrestrial conditions (the Surveyor 3 camera is now on display in the Smithsonian Air and Space Museum in Washington, D.C.).The Surveyor 3 camera was returned from the Moon in a nylon duffel bag, and was not in the type of sealed airtight metal container used to return lunar samples in the early Apollo missions.It is therefore possible that it was contaminated by the astronauts and the environment in the Apollo 12 capsule itself.
