MEMORANDUM **

Gregory Adonis Murphy, a California state prisoner, appeals pro se from the district court’s summary judgment in his 42 U.S.C. § 1983 action alleging deliberate indifference to his serious medical needs. We have jurisdiction under 28 U.S.C. § 1291. We review de novo, Toguchi v. Chung, 391 F.3d 1051, 1056 (9th Cir. 2004), and we affirm.

The district court properly granted summary judgment because Murphy failed to raise a genuine dispute of material fact as to whether defendants were deliberately indifferent to his ear pain and hearing loss. See id. at 1057-60 (difference of opinion concerning course of treatment, medical malpractice, or negligence in diagnosing or treating a medical condition does not amount to deliberate indifference); see also Starr v. Baca, 652 F.3d 1202, 1207 (9th Cir. 2011) (supervisory liability under § 1983 requires “knowledge of and acquiescence in unconstitutional conduct” by subordinates).

The district court did not abuse its discretion by denying Murphy’s motion to appoint counsel because Murphy did not demonstrate any exceptional circumstances. See Palmer v. Valdez, 560 F.3d 965, 970 (9th Cir. 2009) (setting forth standard of review and “exceptional circumstances” requirement for appointment of counsel).

We reject as without merit Murphy’s contention that he was held to a higher standard as a pro se litigant.

AFFIRMED.
