Twenty-three species belonging to 14 genera were identified. This is the first study on intestinal ciliates in domestic horses living in Kyrgyzstan. The mean number of ciliates was 14.1 ± 6.8 x10(4) cells ml(-1) of feces and the mean number of ciliate species per host was 6.0 ± 3.2. No endemic or new species were detected. Blepharocorys was the major genus as these ciliates were detected in high proportions. In contrast Holophryoides, Allantosoma were only observed at low frequencies. Recorded ciliate species in this investigation had almost the same characteristics as those described in previous studies. There was no important geographic variation in the intestinal ciliate fauna of equids.Pubmed Hindgut Ciliate Composition of Thoroughbred Mares in Kentucky, USA, and Binary Fission in Polymorphella ampulla.(2019-07-24T00:00:00Z) Gürelli, Gözde; Lyons, Eugene Thomas; Kesbiç, Fevziye IşilSpecies composition and distribution of hindgut ciliates were investigated in the feces of 20 thoroughbred mares in Kentucky, USA. Thirty-three species and six morphotypes belonging to 21 genera were identified. The average density of hindgut ciliates in mares was 13.5 ± 13.7 × 104 cells ml-1, whereas mean number of ciliate species per host was 14.4 ± 5.3. Bundleia nana, B. elongata, B. piriformis, Blepharoconus hemiciliatus, Holophryoides ovalis, H. macrotricha, Blepharoprosthium polytrichum, Prorodonopsis coli, Paraisotrichopsis composita, Blepharocorys microcorys, and Ochoterenaia appendiculata were the first identified species in horses inhabited in USA. Scanning electron microscopic images of Holophryoides macrotricha, Paraisotrichopsis composita, Cycloposthium dentiferum m. corrugatum, C. edentatum m. edentatum, C. edentatum m. scutigerum, Tetratoxum parvum m. parvum, T. parvum m. sulcatum, T. excavatum m. excavatum, Allantosoma intestinale, and Arcosoma brevicorniger were studied. Binary fission in Polymorphella ampulla was also studied.Publication Importance of Land Snails in Dicrocoeliosis Epidemiology.(2017-09-01T00:00:00Z) Gürelli, GözdeDicrocoeliosis is a helminthosis caused by the small liver fluke Dicrocoelium spp. (Trematoda, Dicrocoeliidae) parasitizing in the bile ducts and gall bladder of ruminants as well as many other animal species including humans. In the biological life cycle of Dicrocoelium, land snails are first intermediate hosts and ants are second intermediate hosts. Sporocysts and cercaria, which are larval stages, live in the hepatopancreas of land snails and metacercaria, which is also the larval stage, lives in the abdomen and brain of ants. Land snails, which are the first intermediate host of this parasite in Turkey, include Helicopsis derbentina, Helicopsis protea, Helicopsis krynickii, Cernuella virgata, Trochoidea pyramidata, Cochicella acuta, Monacha carthusiana, Helicella candicans, Helix aspersa, Helix lucorum, and Chondrus tournefortianus. Dicrocoeliosis is widespread in ruminants and affects their liver, which can lead to weight loss and reduced milk production. The number of reports on dicrocoeliosis is increasing due to the expansion of dry habitats and parasites becoming resistant to antihelminthic drugs. This study provides information on the epidemiology and control methods of Dicrocoelium.Pubmed Importance of Land Snails in Dicrocoeliosis Epidemiology.(2017-09-01T00:00:00Z) Gürelli, GözdeDicrocoeliosis is a helminthosis caused by the small liver fluke Dicrocoelium spp. (Trematoda, Dicrocoeliidae) parasitizing in the bile ducts and gall bladder of ruminants as well as many other animal species including humans.

Species composition and distribution of intestinal ciliates voided in the feces of two Asian elephants were examined. Fifteen species of intestinal ciliates, representing 7 genera, were identified. One new suctorian genus and species, Brevitentaculum antebum n. g., n. sp., was described. This new species has two short truncated terminal projections, with two longitudinally lined bands located between the two projections, near the convex surface of the cell. Short clavate-like tentacles are in two fascicles near each base of terminal projections on the flattened surface of the body. Ciliate densities in the two fecal samples were 4.5×10mL and 10×10mL.Pubmed Intestinal ciliate fauna of the Asian elephant from Gaziantep, Turkey and the description of Brevitentaculum antebum n. g., n. sp.(2016-10-01T00:00:00Z) Gürelli, GözdeThe aims of this investigation were to identify and quantify ciliates inhabiting the large intestine of Asian elephants living in Gaziantep Zoo, Turkey, and to describe a new suctorian genus and species.

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.Publication Intestinal Ciliates of Plains Zebra (Equus quagga Gmelin, 1788) in Turkey.(2023-02-08T00:00:00Z) Gürelli, Gözde; Gurelli, GAn investigation was carried out to identify the intestinal ciliated protozoa of the plains zebra known as Burchell's zebra (Equus quagga burchellii Gray, 1824) living in Sasalı National Park (İzmir, Turkey) and Gaziantep Zoo (Gaziantep, Turkey) and of the plains zebra known as Grant's zebra (Equus quagga boehmi Matschie, 1892) living in Darıca Faruk Yalçın Zoo (Darıca, Turkey). A total of 27 species and 1 morphotype belonging to 17 genera and 6 families were detected. Bundleia elongata was identified in all examined zebras, whereas Bundleia inflata, Blepharoconus benbrooki, Blepharocorys cardionucleata, Circodinium minimum, Cycloposthium bipalmatum, Ditoxum brevinucleatum, D. hamulus, and Arcosoma brevicorniger were identified only in one zebra. The average quantity of intestinal ciliates in the 9 zebras was 11.0 ± 17.0 × 104 cells mL-1. According to this study, the total number of ciliate species in the intestine of zebras increased to 51. This is the first time a report has been made on Paraisotricha colpoidea, Blepharoprosthium polytrichum, Bundleia elongata, B. triangularis, Paraisotrichopsis composita, Arcosoma brevicorniger, and A. dicorniger from zebra intestines. Moreover, A. brevicorniger was observed in binary fission for the first time.Pubmed Intestinal Ciliates of Plains Zebra (Equus quagga Gmelin, 1788) in Turkey.(2023-02-08T00:00:00Z) Gürelli, GözdeAn investigation was carried out to identify the intestinal ciliated protozoa of the plains zebra known as Burchell's zebra (Equus quagga burchellii Gray, 1824) living in Sasalı National Park (İzmir, Turkey) and Gaziantep Zoo (Gaziantep, Turkey) and of the plains zebra known as Grant's zebra (Equus quagga boehmi Matschie, 1892) living in Darıca Faruk Yalçın Zoo (Darıca, Turkey).
