PER CURIAM.

      Missouri inmate Anthony B. Cook appeals the district court’s dismissal of his
42 U.S.C. § 1983 action for failure to exhaust his administrative remedies. We
reverse and remand for further proceedings.

      Cook filed this action naming six defendants; service was effected on three
defendants who sought dismissal of the complaint based on Cook’s failure to state a
claim and to exhaust his administrative remedies. After granting Cook additional time
to respond, the district court dismissed the entire suit because Cook had not
administratively exhausted all of his claims.

      Under 42 U.S.C. 1997e(a), a prisoner must exhaust all available administrative
remedies before a civil action can be brought with respect to prison conditions. See
Graves v. Norris, 

, 885 (8th Cir. 2000) (per curiam). The Supreme Court
recently clarified that administrative exhaustion is an affirmative defense that
defendants have the burden to plead and prove, see Jones v. Bock, 

,
919-22 (2007), and that a lawsuit should not be dismissed in its entirety because some
claims are unexhausted, see 

      We therefore vacate the district court’s order and remand for the court to
dismiss only those claims that are unexhausted.

       Accordingly, we reverse and remand for further proceedings consistent with
this opinion. Cook’s pending motions are denied.
