Prevalence of Ancylostoma braziliense in dogs from Alachua and Marion Counties, Florida, United States.

A convenience collection of fecal samples from 148 dogs in northern Florida was examined for the presence of Ancylostoma braziliense eggs by using centrifugal sugar flotation and polymerase chain reaction (PCR)-restriction fragment length polymorphism (RFLP). Of the 148 samples, 64 (43.2%) contained hookworm eggs. DNA from 42 samples was successfully amplified using PCR; using RFLP, 2 samples were identified as containing DNA of A. braziliense (4.8% of the 42 successfully amplified samples).
