DECISION ORDER
ORDERED that the appeals from the order entered September 24, 1998, are dismissed, as that order was superseded by the order dated October 16, 1998; and it is further,
ORDERED that the order dated October 16, 1998, is reversed, on the law, the motions for summary judgment are granted, the complaint is dismissed insofar as asserted against the appellants, the order entered September 24, 1998, is vacated, and the action against the remaining defendants is severed; and it is further,
ORDERED that the appellants, appearing separately and filing separate briefs, are awarded one bill of costs.
The affidavits of Drs. Mark Goldberger, David Holden, and Joseph Lamantia, submitted by the appellants in support of their respective motions for summary judgment, made a prima facie showing sufficient to warrant judgment in their favor as a matter of law dismissing the instant medical malpractice action insofar as asserted against them ( see, Alvarez v. Prospect Hosp., 68 N.Y.2d 320). The burden then shifted to the plaintiff to lay bare his proof and demonstrate the existence of a triable issue of fact ( see, Holbrook v. United Hosp. Med. Ctr., 248 A.D.2d 358; Spaeth v. Goldberg, 248 A.D.2d 704; McMahon v. Badia, 195 A.D.2d 445; Schaefer v. Marchiano, 193 A.D.2d 664).
The affidavit of the plaintiff's expert merely stated in conclusory terms that the appellants should have diagnosed and treated his bacterial endocarditis sooner. The expert did not adequately differentiate between the different appellants who treated the plaintiff at different times. In fact, the defendant Dr. Robert Phillips, who was not consulted until after the plaintiff's emboli had formed and traveled to his brain, is not mentioned at all in the affidavit. Moreover, the expert made conclusory statements as to the appellants' respective examinations and testing of the plaintiff based either on facts not in evidence or which directly contradicted the evidence. The expert also failed to address the contentions of one of the appellants' experts, Dr. Mark Goldberger, that in order to prevent the plaintiff's embolism, antibiotics would have had to have been administered to the plaintiff before he presented himself to any of the appellants. Accordingly, the affidavit was insufficient to meet the plaintiff's burden of showing a triable factual issue ( see, Holbrook v. United Hosp. Med. Ctr., supra; Spaeth v. Goldberg, supra; Kramer v. Rosenthal, 224 A.D.2d 392).
