ABSTRACT: Twenty-two Florida black bear (Ursus americanus floridanus) cubs (8 mo old. Three cubs had mixed hookworm infections with A. tubaeforme and A. caninum. Over half of the female A. caninum examined were lightly gravid (5-50 eggs), with single-celled eggs located near the ovejectors. Ancylostoma eggs were identified in several fecal samples from cubs, which contained both male and female A. caninum. Brachylaima virginianum Dickerson, 1930 was found in 1 cub from southern Florida. Brachylaima virginianum and A. tubaeforme are new host records, and B. transfuga is reported in black bears from Florida for the first time. The other helminths have been reported previously from black bears. Conti et al. (1983) did not report finding A. caninum in the 46 adult (->2 yr old) black bears from Florida. However, in the same areas where Conti et al. (1983) collected their adult bears, the cubs we sampled were positive for A. caninum. Crum (1977) reported a single female A. caninum in a 10-mo-old black bear cub from Georgia and also a single A. caninum in each of 2 black bears he sampled in Florida. One bear was a 6-yr-old adult (the age of the other bear was not given), but both bears were hunter-kills, so the unaged bear was most likely >18 mo old. Crum et al. (1978) stated that A. caninum was probably an accidental parasite in black bears, evidenced by its low prevalence in 53 bears. Most of the bears examined by Crum et al. (1978) were >18 mo old, with only 5 bears being
