Lespedeza cuneata (poorman’s lucerne; sericea lespedeza), a tannin-rich perennial legume, was offered as hay to dry Merino ewes in a confined feeding experiment to evaluate the effect on the level of gastrointestinal parasite infection in sheep. Medicago sativa (a low tannin containing perennial legume) was used as the control treatment. Parameters faecal egg count (FEC), FAMACHA© scores and rectal temperatures were used. FECs were substantially lower (p = 0.05) in the Lespedeza group after 35 days, together with a trend of higher rectal temperatures, compared with the Medicago group. Although non-significant (p > 0.05), the higher rectal temperatures suggested a lower level of anaemia in the sheep on the Lespedeza ration and, therefore, a lower parasite-worm burden. However, FAMACHA© scores showed no significant (p > 0.05) differences between treatments despite the differences in FEC that were recorded, indicating that host homeostasis was possibly mediated by improved nutrition as a result of the high protein content of both experimental diets.

8OBJECTIVE To develop a method to maintain the initial phenotype of airway smooth muscle (ASM) cells isolated from equine endobronchial biopsy specimens in long-term cell culture. SAMPLE Endobronchial tissue specimens (8 to 10/horse) collected from the lungs of previously healthy horses at necropsy (n = 12) and endobronchial biopsy specimens collected from standing, sedated, heaves-affected horses in clinical remission of the disease (5) and control horses (4). PROCEDURES A sampling protocol was developed to recover and maintain a contractile phenotype in ASM cells from endobronchial specimens from freshly harvested equine lungs and from healthy and heaves-affected horses. Immunologic techniques were used to evaluate the contractile phenotype of ASM cells in culture. RESULTS Characteristic ASM cells were successfully cultured from endobronchial tissue or biopsy specimens from both healthy and heaves-affected horses, and their contractile phenotype was maintained for up to 7 passages. Moreover, the capacity of cells at the seventh passage to contract in a collagen gel in response to methacholine was maintained. CONCLUSIONS AND CLINICAL RELEVANCE ASM cells isolated from equine endobronchial tissue and biopsy specimens were able to maintain a contractile phenotype in long-term cell cultures, suggesting they could be used for tissue engineering and in vitro studies of equine ASM cells.

This study was planned to determine the effect of certain vitamin applications on antioxidant and oxidant parameters in the osteoblast cell line exposed to sodium fluoride in vitro and to evaluate the protective role of certain vitamins against possible toxic effects of fluoride. Cells were replicated in vitro conditions with regular passaging 2-3 times weekly. MTF viability test was used to determine IC50 of NaF (5000μM) and proliferative doses of vitamins (Vitamin A: 10μM, Vitamin D: 10μM, Vitamin E: 60μM, Vitamin C: 100μM) for hFOB 1.19 cells. Cells were sown in flasks as so to be 106. The study groups were identified as control, NaF, vitamins and NaF+vitamins. After incubation for 24 hours, cells treated with trypsin were prepared by freeze/thaw method and MTT viability test, TAS, SOD, GSH, CAT, TOS and MDA analyzes were performed on these samples.In the hFOB 1.19 cell line, TAS levels decreased significantly in the NaF group (p≤0.05), but were close to the control group in NaF+vitamin groups with the exception of vitamin C. However, there was no difference between the groups in terms of GSH level and CAT and SOD activities when the control and NaF groups were compared. It was observed that TOS level increased significantly in the NaF group (p<0.05), decreased in the NaF+vitamin groups and were lower in the NaF+vitamin C and E groups than the control group (p <0.05). While OSI was the highest in the NaF group, no significant difference in MDA level was observed compared with the control group.Conclusion: As a result, it was found that NaF administration in the osteoblast cell line increased oxidative stress and decreased following vitamin application. It was found that the effect of NaF administration in the osteoblast cell line on cell viability was consistent with the oxidative stability and that the vitamin application conformably changed cell viability and oxidative balance.

Canine Brucellosis, the caused by Brucella canis (B. canis), is seen all over the world and the disease is characterized by abortion and infertility. Brucella canis is a zoonotic agent and is transmitted to humans by contact with infected dogs or dog secretions. The aim of this study was to determine the presence of antibodies against Brucella canis in dog serum collected from different provinces of Turkey and the seroprevalence in veterinarians and veterinary faculty students in some of the provinces using Microagglutination Test (MAT). Blood samples collected from 1559 dogs and 225 veterinarians and veterinary faculty students were examined for B. canis antibody titers using MAT method.As a result of the study, B. canis antibody was found to be positive in 12 (0.8%) of 1559 dog serum and in 13 (5.8%) of 225 human serum.5.8% of the B.canis seropositivity we have identified in the risk groups can give an idea of the state of the infection between the Turkish veterinarians and veterinary faculty students.

The objective of this study was to assess the renal function in animals with renal failure after peritoneal dialysis. Animals with kidney failure presented to veterinary teaching hospital at Ankara University consisted of 4 dogs and one cat. Animals with kidney failure were treated with peritoneal dialysisapplication. Concentration of serum urea in all patients significantly decreased after the second attempt of peritonealdialysis but, not serum creatinine. When peritoneal dialysis procedures (4 to 10 times) completed, theconcentrations of serum urea and creatinine were significantly decreased in all animals. Complications identifiedduring PD were peritonitis, hypoalbuminemia, hypokalemia, dialysate retention or leakage from the catheter site,edema and pleural effusion/chylothorax.In the present study, it was concluded that peritoneal dialysis procedure was a life-saving, easily applicable, and cost effective clinical procedure for companion animals with renal failure.

Interpretation of laboratory data is very important and based on comparison with reference intervals in routine practice. Leukocyte term includes all white blood cells and their precursors. These cells use blood circulation for going to the original tissues from their original locations. Total leukocyte count can be changed by various physiologic and pharmacologic reasons. In healthy cats, lymphocytes are the second most frequent leukocyte in the blood. Compared to middle-aged or old cats, young animals have higher absolute lymphocyte counts. The medical records of cats referred to the Ankara University Small Animal Hospitalfor general examination between April 2016 and August 2017 were retrospectively reviewed. Complete bloodcount (CBC) data includes red blood cell (RBC) count, haemoglobin, haematocrit (HCT), mean cell volume(MCV), mean cell haemoglobin (MCH), mean cell haemoglobin concentration (MCHC), red blood celldistribution width, platelet count, white blood cell (WBC) count, neutrophils, lymphocytes, monocytes,eosinophils and basophils.Of 5292 cats, 191 cats at the age between 0 and 1 and with CBC data were included in the study. CBCswere obtained from all 191 cats at the first visit. The relationship of hematological data to the reference range issummarized in Table 2. It was observed that 25.7% of the cats had leucocyte counts below the reference intervaland 3% had above the reference interval. Considering neutrophil counts, it is seen that 23.3% were lower and4.5% were higher. According to the results of 191 hemogram tests, lymphocyte counts of 39 cats (19.3%) andmonocyte counts of 9 cats (4,5%) were found to be low.This is a novel study that includes the results of detailed examination of breed and age distributionof complete blood count results at the first clinical visits of cats. According to our retrospective screening results,it is seen that the relation of monocyte numbers with age is statistically significant. (p = 0.018) The biggestdifference between the two age groups in the study is the pre- and post-adolescence periods. It is important toprecisely know the results of CBC test in the first visit to the clinic and to take the necessary precautions toeliminate the abnormal results before vaccination.

The case was a 2.5-year-old calico cat with an abdominal mass, which was brought from a private clinic to Ankara University, Veterinary Faculty, Animal Hospital, Internal Diseases Clinic. It was reported that the cat was operated 20 days ago, a mass of 8 cm in diameter near the jejunum was removed, but a second mass in the region was noticed in the investigation. The mass removed with operation was found to be Lymphoblastic lymphocarcinoma. In the ultrasonography, a two lobed mass of 3x4.5 cm in size was detected in the mesenterium near the liver. An alternative treatment was considered to be performed instead of reoperation on determining that the mass recurred in a very short time and was malignant as a result of the pathology. Considering that the cat was young and with good general condition, it was decided to administer chemotherapy. Modified Wisconsin Maddison method was selected for the chemotherapy. Shortly after the initiation of the chemotherapy protocol, chemotherapy had to be discontinued due to dense acid accumulation in the abdomen and deterioration of the general condition. Feline Corona Virus was detected positive in the cat scanned for subclinical diseases.

To construct a novel vaccine candidate against bovine enterotoxigenic Escherichia coli (ETEC), FanC, the major subunit of K99 fimbriae adhesion, was inserted into secretion plasmid pYA3560 containing a β-lactamase secretion system. This was then transformed into Δasd Δcrp Salmonella (S.) Typhimurium and designated as JOL950. Secretion of recombinant fanC fimbrial antigens was confirmed by immunoblot analysis. Groups of mice were inoculated with single or double doses of JOL950. Another group was used as a negative control. Compared to control mice, all immunized mice had significantly higher levels (p less than 0.05) of serum immunoglobulin (Ig)G, and secretory IgA against FanC. The IgG2a and IgG1 titer assays revealed that immunization highly induced IgG2a compared to that of IgG1, indicating that T helper-1- related cell-mediated immune responses may be elicited by JOL950. The results show that both systemic and mucosal immunities against selected fimbrial antigens of bovine ETEC expressed by a live attenuated S. Typhimurium strain are prominently produced in mice immunized with JOL950 via an oral route.
