Concentration of Zn, Cu, Mn and Mg in Cattle With Natural Psoroptes Bovis Scabiei
(indian veterinary Journal, 2005) Kozat, S; Ekin, S; Yuksek, N; Kaya, A; Agaoglu, Z
Scabies is caused by Psoroptes bovis. The most cited causes of the disease are the over crowded accommodation of the animals in the barns, malnutrition and imbalanced feeding (Sargison et al., 1995; Sekin et al., 1998). Trace elements and minerals are of a prominent value in terms of increasing the resistance against the disease in the biological organisms, causing severe clinical conditions. in case of their shortage or excess (Underwood and Suttle, 2001). The aim of this study is to find out the levels of zinc (Zn), copper (Cu) Manganese (Mn) and Magnesium (Mg) in Psoroptes scabiei in cattle.
The Effects of Levamisole Poisoning on the Haematological and Biochemical Parameters in Dogs
(M H Schaper Gmbh Co Kg, 2004) Gokce, HI; Gunes, V; Erdogan, HM; Citil, M; Akca, A; Yuksek, N
This study was designed to evaluate possible organ and system disorders associated with experimentally induced levamisole. poisoning in dogs. For this purpose, twelve clinically healthy dogs of different ages, sexes and breeds were used. They were divided into two equal groups (Group A and Group B) and given levamisole orally at a dose of 25 mg/kg of body weight daily for three days. The dogs in, Group B were also injected with atropin sulphate (0.04 mg/kg of body weight) subcutaneously (sc) 1 hour after each administration of levamisole. Routine clinical examinations were made and some haematological, biochemical and blood gas parameters were established at various times after administration of levamisole. The dogs in Group A developed severe neurological signs, gastric haemorrhage, bloody vomiting, colic, anaemia and four dogs died. In Group B these signs were mild and only one dog died. Levamisole poisoning was characterised by a significant reduction in the total number of red blood cells (RBCs), concentration of haemoglobin (Hb) and packed cell volume (PCV), and by anaemia. Peripheral blood pH, actual bicarbonate of plasma (HCO3), actual base excess (BE), partial pressure of oxygen (pO(2)) and saturated oxygen (O(2)SA-O increased in both groups of animals and these dogs developed metabolic alkalosis 48 hours after the first administration of levamisole. The results of the study also show that levamisole poisoning in dogs causes a significant increase in the activity of serum alanine aminotransferase (ALT) and of alkaline phosphatase (AP) and in the concentration of urea in both Group A and Group B. In the study, atropin sulphate reduced the severity of the clinical signs and the number of deaths, but it was not alone sufficient to remedy levamisole poisoning in dogs.
Effects of Prolonged Intravenous of Flunixin Meglumine in Healthy Dogs
(veterinarni A Farmaceuticka Univerzita Brno, 2003) Erdogan, HM; Gunes, V; Gokce, HI; Uzun, M; Citil, M; Yuksek, N
This study was designed to evaluate possible side effects on liver and kidney functions and haematological indices, associated with long-term intravenous (IV) administration of flunixin meglumine in healthy dogs. For this purpose, 12 dogs were divided into 2 equal groups. Group 1 was intravenously given flunixin meglumine at the dose of 1.1 mg/kg/day for 5 days and g-roup 11 received 2.2 mg/kg/day IV for 5 days. Blood samples were withdrawn before treatment (day 0), 2 h post injection on each day of treatment and one day after the last injection for biochemical (glucose, sodium-Na, potassium-K, chloride-Cl, creatinine, urea, alkaline phosphatase-AP, alanine amino transferase-ALT and total protein) and haematological (bleeding time, coagulation time, red blood cell, white blood cell, platelet count, differential leukocyte count, haematocrit and haemoglobin) analyses. Faecal and urine samples were collected on the same days as blood samples for the presence of any abnormalities. The results revealed a significant increase in bleeding (P < 0.001) and coagulation time (P < 0.001) and a decrease in platelet count (P < 0.001) in both groups. There was also a significant increase in the concentration of Na and Cl in group 1 and an elevation in AP (P < 0.00 07 ALT (P < 0.001) and glucose (P < 0.001) in group II. Blood in urine and faeces was also evident in both groups. The results may suggest that the dose of 1.1 mg/kg IV for 5 d does not cause any significant side effects provided that no bleeding disorder exists. and the dose of 2.2 mg/kg IV for 5 d should not exceed 3 d as liver enzymes began to increase significantly afterwards.
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.
Zygomycotic Proventriculitis and Ventriculitis in Ostriches (Struthio Camelus) With Impaction
(Australian veterinary Assn, 2000) Gulbahar, MY; Agaoglu, Z; Biyik, H; Yuksek, N
Three young ostriches (Struthio camelus), aged 4 months, were found to have zygomycotic proventriculitis and ventriculitis associated with impaction. Clinical signs were anorexia, chronic weight loss, weakness and lethargy followed by scant faeces for seven days. Proventriculi and ventriculi from birds were full of masses of hay, grass, leaves and other fibrous materials in combination with sand, gravel and plastic. Erosions and haemorrhagic ulcers of varying number and severity were present in the mucosae of both organs involved. Mucosal lesions were characterized by haemorrhagic necrosis. Throughout the affected mucosae there were 5 to 12 mu-m wide rarely-septated fungal hyphae with non-parallel walls, irregular branching and occasional globoid distentions, typical of Zygomycetes. Zygomycotic proventriculitis and ventriculitis secondary to impaction was diagnosed.
