Intestinal ciliated protozoa of the Asian elephant Elephas maximus Linnaeus, 1758 with the description of Triplumaria izmirae n. sp.

Abstract

Species composition and distribution of intestinal ciliates excreted in the feces of three Asian elephants living in Sasalı National Park, Izmir, Turkey, were investigated. Seven ciliate genera consisting of 36 species were identified. This is the first report on intestinal ciliates in elephants living in Turkey; one new species, T. izmirae n. sp., was described. This new species has a special macronucleus shape, skeletal rod plates with two wings and posterior contractile vacuole lying beneath the dorsal left base of the tail flap. The buccal infraciliary bands of T. izmirae are similar to those of T. selenica and T. suwako known from elephants. Triplumaria ovina and Raabena bella occurred in highest percentages in two elephants, whereas Latteuria polyfaria was highest in the third one. Ciliate densities in the three fecal samples were 3.5, 1.5 and 5.0 × 10(4)/mL.
