          Appeals from the United States District Court
                for the Southern District of Texas
                       USDC No. 3:03-CV-998
                       --------------------

Before KING, HIGGINBOTHAM, and GARZA, Circuit Judges

PER CURIAM:*

     The plaintiffs, all Texas prisoners who have tested positive

for the Hepatitis C Virus (HCV), appeal the district court’s

order granting summary judgment to the defendants in their 42

U.S.C. § 1983 suit.   In their suit, the plaintiffs alleged that

     *
       Pursuant to 5TH CIR. R. 47.5, the court has determined that
this opinion should not be published and is not precedent except
under the limited circumstances set forth in 5TH CIR. R. 47.5.4.
                            No. 05-40715
                                 -2-

the defendants were and remain deliberately indifferent to their

serious medical needs by failing to provide adequate testing and

treatment for HCV.   The plaintiffs have received treatment for

HCV, but they argue that the defendants have failed to comply

with the accepted standard of care.   The plaintiffs fail to show

that the defendants have been deliberately indifferent, however,

because their disagreement with their specific courses of

treatment is insufficient to establish deliberate indifference.

See Domino v. Texas Dep’t of Criminal Justice, 

, 756

(5th Cir. 2001) (stating that deliberate indifference requires a

showing that prison officials acted with wanton disregard for

medical needs); Varnado v. Lynaugh, 

, 321 (5th Cir.

1991) (stating that unsuccessful medical treatment, negligence,

neglect, and malpractice are insufficient to give rise to a

§ 1983 cause of action).   Because the plaintiffs do not brief the

district court’s dismissal based on sovereign immunity of UTMB

and the Texas Tech University Health Sciences Center, their

claims against those defendants are abandoned.    See Yohey v.

Collins, 

, 224-25 (5th Cir. 1993).

     The plaintiffs also argue that the district court

erroneously denied their motions for class certification and for

appointment of counsel.    The magistrate judge originally denied

class certification subject to reconsideration as the case

developed.   We conclude that the district court did not abuse its

discretion by granting summary judgment without re-examining the
                            No. 05-40715
                                 -3-

certification issue.    See Bell Atlantic Corp. v. AT&T Corp., 

, 301 (5th Cir. 2003); Floyd v. Bowen, 

, 534

(5th Cir. 1987).    The district court also did not abuse its

discretion by denying the motion for appointment of counsel.     See

Ulmer v. Chancellor, 

, 212-13 (5th Cir. 1982); FED.

R. CIV. P. 23(g).

     The plaintiffs further argue that the district court failed

to rule on their motion to strike an affidavit in support of the

defendants’ summary judgment motion and that the district court

erroneously relied on the defective affidavit.    The district

court’s denial of the motion was implicit in its order granting

summary judgment.    See Norman v. Apache Corp., 

, 1021

(5th Cir. 1994).    Further, by attempting to incorporate by

reference arguments made in their motion to strike, the

plaintiffs have inadequately briefed how the affidavit was

defective.    See Peel & Co., Inc. v. The Rug Market, 

,

398-99 (5th Cir. 2001); 

.

     Finally, the plaintiffs argue that the district court

erroneously denied their motion for a preliminary injunction.     We

conclude, however, that the district court did not abuse its

discretion.   See White v. Carlucci, 

, 1211 (5th Cir.

1989) (stating that this court reviews the denial of a

preliminary injunction for an abuse of discretion and will

reverse “only under extraordinary circumstances”).

     AFFIRMED.
