An infection that was found following his return to England from the United States after an unsuccessful attempt in the Breeders' Cup Turf (G1) has voided the sale of Mutamam (GB) to the National Stud. Plans called for the six-year-old son of Darshaan to be sold by Sheikh Hamdan bin Rashid al Maktoum's Shadwell Estate Co. to the National Stud but a Klebsiella infection detected during a final veterinary exam led to the cancellation of the sale. Mutamam is still expected to stand at the National Stud near Newmarket, England. He will stand his first season for $8,877.

Caused by bacteria found in human and animal colons that can attack people with weak immune systems and affect the gastrointestinal tract, Klebsiella infections are often urogenital infections in animals. The infection can be derived from contaminated bedding and it can be spread from stallions to mares during breeding.

Veterinary surgeons representing both Shadwell and the National Stud are treating Mutamam, who is scheduled to be included in the farm's stallion parade on December 1-2.

Winner of the Canadian International Stakes (Can-G1) prior to his 11th-place finish in the Breeders' Cup, Mutamam retired with 11 wins in 21 career starts for $1,388,410 in earnings. He also won the 2001 Princess of Wales's Stakes (Eng-G2), 2000 Cumberland Lodge Stakes (Eng-G3), and four other English stakes during his career.

Bred in England by Biddestone Stud, Mutamam is out of the stakes-placed Caerleon mare Petal Girl.
