摘要: Intestines of California sea lion (Zalophus californianus) pups (n= 204), born in 2002 on San Miguel Island, California, were examined for hookworms (Uncinaria spp.) as part a seasonal mortality study from June through December and January 2003. The investigation was planned to coincide with most the previously established hookworm infection period pups. Prevalence dead 100% each month study. geometric mean intensity infections per was: 94.03 (n=30) June, 629.09 (n=50) July, 319.90 (n=31) August, 159.90 October, 109.03 November, 37.84 (n=24) 11.05 (n=9) In addition temporal pattern, higher good condition male An inter-year comparison counts collected July 1996, 2000, also demonstrated better but sex-differences inconsistent across years. intensities portions rookery sandy substrate versus rocky substrate. No annual differences found after adjusting condition.
