Near midair collision between a B737-300 climbing through 1000 ft after takeoff and an small aircraft climbing across their flight path only 100 ft above. The flight crew of the B737 had no time to take evasive action since they were not alerted by an ATC advisory and their TCASII had just given a TA alert.

Narrative:
Departed runway 9L at mia runway heading to 5000 ft per clearance. At approximately 1000 ft AGL we received a TCASII TA. Conflict aircraft was slightly to left and then overhead at +100 ft. We never had a visual nor did ATC issue a warning. We questioned ATC and they said small propeller aircraft had departed opa locka on 90 degree heading and turned to 180 degree heading perpendicular to our flight path.
