Enzyme Activities in Fascioliosis of Cattle
(indian veterinary Journal, 2005) Bicek, K; Deger, Y; Deger, S
Significant pathological disorder occur in the liver and biliary tracts in fascioliasis due to the migration of parasites. Enzymes released from the affected hepatic cells pass into the blood and bring about some changes in the early stages of the disease (Baysu et al., 1971). An increase in the activities of secretion of enzymes like GOT and ALP is believed to be an important factor in acute cellular disorders, however this factor becomes much more conspicuous in the obstruction of hepatic and biliary tracts (Benjamin, 1978). ALP, GOT, GPT and LDH enzymes are found in abundance in metabolically active tissues. Since GOT, GPT and LDH are enzymes controlling the fundamental reactions in the metabolism, their activities in the serum exacerbated due to massive tissue disruption (Kramer, 1980). This investigations deals with the changes occurred in GOT, GPT, LDH, GGT and ALP activities in the serum of cattle infected with fascioliosis.

(Tubitak Scientific & Technological Research Council Turkey, 2005) Akkan, HA; Karaca, M; Tütüncü, M; Özdal, N; Yüksek, N; Agaoglu, Z; Deger, S
The present study was conducted to determine prevalence of Haemobartonella felis in Van cats. 121 Van cats (82 female, 39 male, aged 1-9 years) were the materials of the study, To determine biochemical and haematological parameters, 2 ml blood with and without anticoagulant were taken according to technique from vena cephalica antebrachii. H. felis was detected in blood smears preparations of 18 (14:88%) by Papenheim staining. Among biochemical parameters aspartate amino transferase (AST), alanine amino transferase (ALT), alkaline phosphatase (ALP), creatine phosphokinase (CPK) and bilirubin were in normal range as well as the packed cell volume (PCV) and red blood cell (RBC) counts. The infected cats were treated with oxytetracycline at 10 mg/kg dose intramuscularly (Geosol((R)) flacon, Vetas) or oral oxytetracycline at 10 mg/kg dose (Neoterramycine((R)) pow. Pfizer) for 15 days. After either above treatment blood smear preparations revealed negative for the rickettsia. In conclusion, potentially lethal infection of Haemobartonelia felis is prevalent in Van cats and can successfully be cured by oral or parenteral oxytetracycline application.

Oxidation Products of Nitric Oxide and the Concentrations of Antioxidant Vitamins in Parasitized Goats
(Vysoka Skola veterinarni Farmaceuticka, 2002) Dede, S; Deger, Y; Kahraman, T; Deger, S; Alkan, M; Cemek, M
The status of nitric oxide oxidation products and antioxidant vitamins were investigated in goats infected with endoparasites and blood parasites (Trichostrongylidae sp. + Protostrongylidae sp. + Eimeria sp. + Babesia sp.), in this study. Eighteen goats were naturally infected with these parasites and ten healthy goats served as controls which had been treated with antiparasitic drugs after parasitological examinations were carried out. The concentrations of nitric oxide oxidation products (nitrate, nitrite) and antioxidant vitamins (vitamins E And C, beta-carotene and retinol) were determined spectrophotometrically in the blood serum of all Pats. The results were expressed as nitrate (mug/ml) 7.25 +/- 1.31-4.69 +/- 0.32; nitrite (mug/ml) 1.52 +/- 0.39-1.64 +/- 0.19; vitamin E (mg/100) 0.13 +/- 0.05-0.42 +/- 0.02; vitamin C (mg/100 ml) 1.49 +/- 0.26-1.46 +/- 0.15; retinol (g/100 ml) 201.51 +/- 15.69-234.081 +/- 45.15; beta-carotene (g/100 ml) 62.71 +/- 7.14-53.95 +/- 3.82. In conclusion, nitrate concentrations of the infected group were higher than controls (p < 0.05) whereas vitamin E levels of the infected group were lower than the control group (p < 0.05). The concentrations of the other indices examined were not statistically different between groups. These results suggest that the parasitic infections have direct effects on the concentrations of vitamin E, an important antioxidant, and on the increase of nitrate levels which may result from the pathophysiological effects of the parasitic infections.

Prevalence of Cryptosporidium Infection in Van Cats
(indian veterinary Journal, 2005) Goz, YR; Yuksek, N; Altug, N; Ceylan, E; Deger, S
Cryptosporidium infection is a zoonotic disease caused by Cryptosporidium spp. and transmitted by faecal-oral cycle. Young animals are most likely to develop symptomatic infections and shed high quantities of infective oocysts. But infection in adult animals is asymptomatic and number of oocysts shed is usually very fewer than from young animals. (Bukhari and Smith, 1999). The aim of present study was to investigate the prevalence of Cryptosporidium spp. in Turkish Van Cats. Materials and Methods Forty six cats 96 kitten and 40 adult Van cats) from Van Cat House, aged between 16 weeks and 7 years were used in this study. Direct smear method and then formalin-ether sedimentation method were carried out to detect intestinal parasites from faecal samples of cats (n=46). The smears were stained by Modified Ziehl-Neelsen Method for identifying the red-pink oocyst of cryptosporidium. Results and Discussion Cryptosporidium sop. are coccidial protozoon belonging to the phylum Apicomplexa which inhabit the intestinal and respiratory surface epithelium of mammals, birds and reptiles. The first species of this genus was recognized in gastric glands of the laboratory mice in 1907 and was named Cryptosporidium muris (Tyzzer, 1907). In Cryptosporidium spp. has been reported from the faeces of 13 non-feral Japanese cats (Iseki,- 1979). Cryptosporidium prevalence was found to be 3.8% (Arai et al., 1990; Spain et al., 2001), 5.4% (Hill et al., 2000) and 8.1% (Mtambo etal., 1991) in other studies. In the present study, it was detected that all kittens (n=6) were infected by Cryptosporidium spp. (13.0%). No cryptosporidium oocysts were found in adult cats. Similarly, previous reports indicate that more young animals are infected with Cryptosporidium spp. Than old animals (Bukhari and Smith, 1999). Pets and farm animals with Cryptosporidium and other parasitic infections may be important sources and great risk factor for immunocompromised adults and children, especially those with AIDS (Lewis et al., 1985). In the present study, in addition to Cryptosporidium spp. Other gastrointestinal parasites including Toxocara cati (15.2%), Taenia taeniaeformis 4.3%), Giardia spp. (6.5%) and Isospora felis (2.17%) were detected. Infection incidence with only one species of parasite was more common than infection with multiple parasite species. One kitten was infected with one helminth (Toxocara cati) and two protozoa (Giardia spp. and Isospora felis). Toxocara cati was the most prevelant helminth (15.2%), followed by Taenia taeniaeformis (4.3%). Giardia spp. was detected in one adult and two kittens. Isospora felis was detected in only one kitten. Cryptosporidium infection in kittens and healthy or immunodepressed. cats can cause a spectrum of diseases from an asymptomatic state to mild, transient diarrhoea and cholera-like illness; or prolonged and life threatening malabsorption syndrome. In young animals with cryptosporidium infection, there is dehydrating diarrhoea caused by development of the parasites within the epithelial cells of the intestinal. mucosa (Tzipori et al., 1983). In the present study, no clinical symptoms including diarrhoea were found in young cats with cryptosporidium oocysts in their faecal smears. These results agree with the result of Iseki (loc. cit.). There have been reports linking feline cryptosporidiosis to human infection. (Bukhari and Smith, loc. cit.; Mtambo et al., loc. cit.). But many cat owners and breeders are not aware of feline zoonotic parsites and their mode of transmission to humans. Thus, the veterinarians have a great role in educating the cat owners and breeders regarding the transmission of zoonotic parasites such as cryptosporidium.
The Prevalence of Eimeria Species in Goats in Van
(Tubitak Scientific & Technological Research Council Turkey, 2003) Deger, S; Gül, A; Ayaz, E; Biçek, K
This study was carried out to determine Eimeria infection in goats in nine different districts in Van province in Turkey. Faecal samples (approximately 3-5 g) were obtained from the rectums of 242 goats. The samples were examined by Sheather's sugar flotation technique and determined microscopically for the presence of oocysts. Eimeria species were identified following sporulation of faeces in a thin layer of 2.5% potassium dichromate for one or two weeks at 25 degreesC. All samples were later examined for identification of Eimeria species. Nine different species of Eimeria oocysts were detected in 73.6% of the goats. These species were E. arloingi (40.9%), E christensini (34.3%), E. alijevi (32.6%), E. pallida (31.0%), E. hirci (30.2%), E. ninakohliyakimovae (29.8%), E. jolchijevi (26.0%), E. apsheronica (5.8%), and E. punctata (0.8%). Mixed infections were widespread (66.9%). Clinical eimeriosis was not observed.
