Novel and Canine Genotypes of Giardia duodenalis in Harbor Seals (Phoca vitulina richardsi)

摘要: Abstract Feces of harbor seals (Phoca vitulina richardsi) and hybrid Glaucous-winged/Western gulls (Larus glaucescens/ occidentalis) from Washington State's inland marine waters were examined for Giardia spp. Cryptosporidium to determine whether genotypes carried by these wildlife species the same as those that commonly infect humans domestic animals. Using immunomagnetic separation followed direct fluorescent antibody detection, cysts detected in 42% (41/97) seal fecal samples. spp.–positive samples came 90% (9/10) sites, prevalence positive differed significantly among study sites. Fecal collected haulout sites with >400 animals 4.7 times more likely have than at smaller In gulls, a single sp. cyst was 4% (3/78) oocysts not any or tested....
