Öğe Acute phase proteins, clinical, hematological and biochemical parameters in dairy cows naturally infected with anaplasma marginale(KAFKAS UNIV, VETERINER FAKULTESI DERGISI, 2012) Coskun, Alparslan; Ekici, Ozlem Derinbay; Guzelbektes, Hasan; Aydogdu, Ugur; Sen, IsmailThe aim of the study was to evaluate acute phase response via Haptoglobin and serum amyloid-A concentrations in dairy cows naturally infected with Anaplasma marginale. The second aim of the study was to determine the changes in clinical, hematological and biochemical parameters in dairy cows naturally infected Anaplasma marginale. A total of 40 dairy cattle suffering from bovine anaplasmosis were included to the study from a dairy cattle herd. A total of 10 healthy dairy cattle were selected for control group. Analysis of acute phase proteins, hematologic analysis and biochemical analysis was performed in this study. Serum haptoglobin and serum amyloid-A concentrations significantly increased in cattle infected with Anaplasma marginale compared to healthy cattle. All cattle in infected group demonstrated clinical signs of anaplasmosis. Significantly decreased red blood cell count, packed cell volume, and hemoglobin concentration were observed in infected cattle compared to the control group. Serum aspartate aminotransferase, alkaline phosphatase, creatinine and bilirubin concentrations were significantly increased in infected cattle compared with the control group. In conclusion, the changes of biochemical and hematological parameters may be indicate of anemia and tissue damage in cattle with anaplasmosis. Serum haptoglobin and serum amyloid-A concentrations could be usefull in evaluate of acute phase response in cattle infected with Anaplasma marginale.Öğe Acute phase response and clinical changes in calves with lipopolysaccharide induced endotoxemia(Selçuk Ünivesitesi Veterinerlik Fakültesi, 2012) Coskun, AlparslanAmaç: Lipopolisakkarit ile deneysel endotoksemi oluşturulan buzağılarda akut faz proteinlerin ve klinik değişimlerin belirlenmesi amaçlanmıştır. Gereç ve Yöntem: Çalışmada yaşları 25-42 gün arasında değişen sekiz adet Holstein ırkı buzağı kullanıldı. Lipopolisakkarit damar içi 0.1 µg/kg dozunda 50 mL % 0.9 NaCl’de seyreltilip 30 dakika süresince verilerek endotoksemi oluşturuldu. Çalışma boyunca endotoksemi gelişen buzağılarda klinik olarak gözlenen değişiklikler kayıt edilirken ve akut faz proeinlerinin konsantrasyonları belirlendi. Bulgular: Lipopolisakkarit uygulanması sonrasında buzağıların tamamında solunum sayısında ve kalp atım sayısında artış, yerde yatma, depresyon, hipotermi/hipertermi mukozada hiperemi/siyanoz ve emme refleksinde azalma gözlendi. Klinik olarak gelişen değişimler 1. ve 3. saatler arasında daha şiddetli olduğu belirlendi. Damar içi lipopolisakkarit verilmesinden sonra haptoglobin 36. saatte (500±93.2 µg/ mL) ve serum amyloid-A 24. saatte (185± 46.6 µg/mL) en üst seviyeye ulaştı. Öneri: Akut faz proteinlerde ve klinik bulgulardaki gözlenen değişim, buzağılarda gelişen endotoksemi ile ilişkilidir. Buzağılarda serum haptoglobin ve serum amyloid-A konsantrasyonlardaki artışlar endotokseminin bir belirteçi olarak değerlendirilebilir.Öğe CARDIAC BIOMARKERS IN PREMATURE CALVES WITH RESPIRATORY DISTRESS SYNDROME(AKADEMIAI KIADO RT, 2016) Aydogdu, Ugur; Yildiz, Ramazan; Guzelbektes, Hasan; Coskun, Alparslan; Sen, IsmailThe aim of this study was to determine the clinical relevance of cardiac biomarkers [troponin I and T, creatine kinase-MB fraction (CK-MB) and lactate dehydrogenase (LDH)] in premature calves with respiratory distress syndrome. Seventy premature calves were admitted to the clinic within 24 h after birth. Respiratory distress syndrome was diagnosed in premature calves by clinical examination and venous blood gas analysis. Ten healthy calves, aged 5 days, were used as control. Cardiac troponin I and T were analysed using ELISA and ELFA, respectively. Serum CK-MB and LDH were also analysed in an automatic analyser. The calves had low venous pH, pO(2), O-2 saturation and high pCO(2) values consistent with dyspnoea, hypoxaemia, and inadequate oxygen delivery. Mean serum troponin I, troponin T, CK-MB and LDH levels were increased in the premature calves compared to the control group. In conclusion, the results in this study demonstrated that serum CK-MB, troponin I and troponin T concentrations could be used for evaluating myocardial injury in premature calves with respiratory distress syndrome.Öğe Comparison of the Effectiveness of Halofuginone Lactate and Paromomycin in the Treatment of Calves Naturally Infected with Cryptosporidium parvum(UNIV FED RIO GRANDE DO SUL, 2018) Aydogdu, Ugur; Isik, Nermin; Ekici, Ozlem Derinbay; Yildiz, Ramazan; Sen, Ismail; Coskun, AlparslanBackground: Cryptosporidiosis is one of the most important problems among neonatal ruminants. Cryptosporidium parvum is the agent causing the disease. Cryptosporidium infection, responsible for diarrhea, dehydration, weight loss and death in neonatal ruminants, leads to significant economic losses for producers. In calves naturally or experimentally infected with cryptosporidiosis, many agents have been reported to have therapeutic and protective effects. The objective of this study was to compare the effectiveness of halofuginone lactate and paromomycin in the treatment of calves naturally infected with Cryptosporidium parvum. Materials, Methods & Results: Twenty calves between 7 and 20 days of age and naturally infected were included in the study. There were two different treatment groups in the study. The first group of calves were administered 100 mu g/kg/day halofuginone lactate for 7 days and the second group of calves were administered 100 mg/kg/day paromomycin for 7 days. In addition, antibiotic and vitamin C were applied to all calves. Jugular venous blood samples were obtained pre-treatment and on the 7th day after the treatment. Routine clinical examinations of the calves were performed on days 0, 1, 3, 5 and 7 and rectal stool samples were collected for the detection of Cryptosporidium oocysts. Severe diarrhea, dehydration, depression and weight loss were observed in calves in both treatment groups. A significant decrease (P < 0.05) was observed for both groups in oocyst count on days 3, 5 and 7 compared to days 0 and 1. Improvements in blood parameters, stool characters and clinical scoring of both groups were observed in post-treatment. Discussion: Many pharmaceuticals or compounds have been tested for animal with cryptosporidiosis and only very few of them have shown a partial protective activity in ruminants when used prophylactically. Halofuginone lactate and paromomycin are commonly recommended as both therapeutic and protective agents. However, the effectiveness of the two therapeutic agents in natural infections has not been compared and, in the meantime, recommendations for a rational use are also not sufficiently documented in calves with cryptosporidiosis. Paromomycin is an aminoglycoside antibiotic used to control C. parvum infection in animals. Paromomycin reduces oocyst shedding and the number of days with diarrhea in experimentally infected calves when used prophylactically. Halofuginone lactate is a synthetic quinazolinone with cryptosporidial activity in the merozoite and sporozoite stages of C. parvum. It is recommended for both therapeutic and prophylactic use in cryptosporidiosis. In this study, although paromomycin (100 mg/kg/day for 7 days) and halofuginone lactate (100 mu g/kg/day for 7 days) led to a decrease in oocyst shedding from day 1, a statistically significant decrease (P < 0.05) was observed from day 3. The results of this study show that the decrease in oocyst shedding in both treatment groups, improvements in clinical findings and recoveries in hematologic, blood gas and serum biochemistry values are similar. Even though these drugs do not eliminate the infection, they decrease both the severity of diarrhea and contribute to recovery. In conclusion, the results of this study indicated that halofuginone lactate and paromomycin were effective in the treatment of calves naturally infected with cryptosporidiosis. Therefore, we recommend that both drugs should be used in the treatment of calves naturally infected with Cryptosporidium parvum.Öğe Efficacy of oral rehydration therapy solutions containing sodium bicarbonate or sodium acetate for treatment of calves with naturally acquired diarrhea, moderate dehydration, and strong ion acidosis(AMER VETERINARY MEDICAL ASSOC, 2009) Sen, Ismail; Altunok, Vahdettin; Ok, Mahmut; Coskun, Alparslan; Constable, Peter D.Objective-To determine and compare the effects of 4 oral replacement therapy (ORT) solutions on acid-base balance, abomasal emptying rate, and plasma volume expansion in calves with naturally acquired diarrhea and moderate dehydration. Design-Prospective study. Animals-20 calves. Procedures-20 calves up to 45 days of age were randomly allocated (n = 5/group) to receive 2 L of 1 of 4 treatments via oroesophageal intubation: sodium bicarbonate (150 mmol/L or 300 mmol/L) or sodium acetate (150 mmol/L or 300 mmol/L). The 4 test solutions contained acetaminophen (50 mg/kg [22.7 mg/lb]) and 50 g of glucose monohydrate. Jugular venous blood samples were obtained periodically before and after administration of the ORT solution. Abomasal emptying rate was determined by use of the time to maximal plasma acetaminophen concentration. Results-Plasma bicarbonate concentration increased more rapidly in calves administered bicarbonate-containing ORT solutions, whereas the rate of systemic alkalinization, as assessed via blood pH, did not differ consistently among treatments. The 300 mmol/L ORT solutions were emptied at a significantly slower rate from the abomasum than 150 mmol/L ORT solutions, with no difference in emptying rate between acetate and bicarbonate-containing ORT solutions of similar molality. The 300 mmol/L sodium acetate ORT solution significantly increased plasma volume. Conclusions and Clinical Relevance-Clinically important differences in the resuscitative response to 300 mmol/L or 150 mmol/L ORT solutions of sodium acetate or sodium bicarbonate were not identified.

Generally, absence of defecation in calves less than 10 days old, diminishing appetite, progressing abdominal distention and time-developing depression are reported in atresia coli. Although a calf consumes its milk normally in first days, loss of appetite develops over time. Occasional minor pain indications are observed. The objective of this study was to evaluate of hematologic, blood gases, cardiac biomarkers and serum biochemical parameters before operation in calves with atresia coli, and to investigate relationship with prognosis of these parameters. Materials, Methods & Results: Thirty calves with atresia coli and 6 healthy calves for control were used as material. Poor suction reflex, anorexia, dehydration, abdomen-kicking, frequent leg movement, abdominal distension and depression were observed in calves brought to the clinic. Some calves presented swashing sound depending on content of intestines when abdomen was shaken. Intestine atresia was diagnosed by history and clinical examination. After clinical examination, operation was performed. All calves were observed during 10 days after operation. Fifteen of 30 calves died during 10 days after operation. The blood lactate, WBC, LDH and CK-MB levels in non-surviving calves with atresia coli were significantly higher compared to control calves. The venous blood pH level was significantly lower in non-surviving calves compared to surviving calves. In addition, when compared to the control group, the blood pCO(2) level was significantly higher in non-surviving and surviving calves with atresia coli while the pO(2) and O-2 saturation levels were significantly lower. Discussion: In calves with intestinal atresia, hematologic parameters are normal in first 48 h of disease. However, leukocytosis and shift to the left have been reported over time. However, leukocytosis due to peritonitis, bacterial overgrowth, etc. have been reported over time. It was seen that leukocyte numbers of non-surviving calves with atresia coli in this study were significantly higher, but leucocyte increase in surviving calves was seen to be statistically insignificant. Leukocyte increased in non-surviving calves with atresia may be associated with excessive bacterial reproduction and peritonitis. Blood lactate level is a commonly used marker for severity of disease in humans and lactate has a prognostic value in adult horses with colic and foals with critical disease. In this study, lactate level in non-surviving calves with atresia coli was significantly higher with respect to surviving calves and control calves. In this result, lactate can be evaluated as a prognostic indicator in calves with atresia coli. Creatine kinase-MB fraction and troponins are used in determination of cardiac damage in veterinary medicine. The fact that serum blood cTnI and CK-MB levels of non-surviving calves with intestinal atresia in this study were higher than surviving calves with atresia coli and control calves suggested that endotoxemia related cardiac damage may have developed. Surgical operation is necessary in the treatment of intestinal atresia. It was determined that the importance of calves age and colon integrity during time of surgical operation in survival of calves with atresia coli. The studies showed that survival rate in surgical operation conducted on calves under 3 days old was higher than calves over 5 day-old. Average of age of non-surviving calves with atresia coli in this study (4.67 +/- 1.23 days) was higher than average of age of surviving calves with atresia coli (3.27 +/- 0.51 days). It was also observed in our study that elapsed time affected prognosis of calves negatively. Thus, performing surgical operations as soon as possible may raise survival rate of calves with intestinal atresia as stated in previous studies.Öğe NMR-based metabolomic evaluation in dairy cows with displaced abomasum(SCIENTIFIC TECHNICAL RESEARCH COUNCIL TURKEY-TUBITAK, 2014) Basoglu, Abdullah; Baspinar, Nuri; Coskun, AlparslanThis study is the first to evaluate nuclear magnetic resonance (NMR) -based metabolomics in cows with displaced abomasum (DA), which is an internationally recognized problem in dairy cows. Some biochemical parameters have been used for monitoring DA. However, to date, few data have been available on the blood metabolomic profile of dairy cows. Forty Holstein multiparous cows with DA (30 left, 10 right) and 10 clinically healthy Holstein multiparous cows were the subjects of the study. All the animals had similar dry matter intake. An NMR-based metabolomics approach and hematological and biochemical analyses were performed. Some changes in biochemical parameters were observed between the groups. Among the cows with left displaced abomasum (LDA), 10 were associated with concomitant ketosis. Disease periods between the 2 DA groups were different. The metabolites identified and quantified by NMR analysis were valine, 3 beta-hydroxybutyrate (BHB), alanine, glutamine, glutamate, and succinate. The last of these was significantly decreased in cows with right displaced abomasum (RDA). Glutamine, glutamate, and 3 BHB levels were significantly different between DA groups. There was a positive correlation between BHB and valine, glutamine, and glutamate in the LDA group. Overall, this work suggests that the additional information obtained by NMR-based metabolomics evaluation may contribute to assessing the metabolic status of cows with DA.Öğe POST-PARTURIENT HAEMOGLOBINURIA IN THREE DAIRY COWS. A CASE REPORT(NATL VETERINARY RESEARCH INST, 2009) Ok, Mahmut; Guzelbektes, Hasan; Sen, Ismail; Coskun, Alparslan; Ozturk, Aliye SagkanThe changes in some biochemical and haematological parameters in three cows with post-parturient haemoglobinuria were described. The animals were 4, 6, and 7 years of age. These cows had calved in the autumn. Post-parturient haemoglobinuria in the cattle occurred at a post-partum of about 3 weeks. The cows received phosphorus supplementation and supportive treatment. The mean serum phosphorus level in the affected cows was significantly lower compared with healthy cows. In the meantime, the blood RBC, PCV, MCHC, and Hb values were also significantly lower compared with healthy cows. In conclusion, the deficiency of phosphorus could be responsible for the development of post-parturient haemoglobinuria in the cows.Öğe Relationship between the degree of dehydration and the balance of acid-based changes in dehydrated calves with diarrhoea(NATL VETERINARY RESEARCH INST, 2007) Guzelbektes, Hasan; Coskun, Alparslan; Sen, IsmailThe aim of the study was to investigate acid-base changes and to determine some serum biochemical parameters in dehydrated calves with diarrhoea according to the degree of dehydratation. Thirty diarrhoeic dehydrated calves submitted to treatment in the university clinic, were used in the study. The calves were accessed as suitable for this study, if they were moderately or severely dehydrated according to clinical symptoms. All sick calves had the usual yellow and watery diarrhoea. Calves with 4% to 8% dehydration (moderate) had a weak suckle reflex, dry mucous membranes, warm mouth and partly good muscular tone. Calves with 10% and above dehydration (severe) were unable to stand, and had no suckling reflex and cold mouth. The mean pH, base excess, chloride (only severely dehydrated group) and sodium were significantly decreased in both moderately and severely dehydrated groups. On the other hand, potassium, phosphorus, HCO3- and anion gap levels were increased, compared to that of the control group. Results of this study showed that there was a relationship between the base excess and anion gap, with a degree of clinical dehydration. However, there may not be an exact correlation between the degree of dehydration and the severity of acidosis. Based on the clinical symptoms, the results of this study could be a useful tool under field conditions, in estimating the base excess in diarrhoeic dehydrated calves, when acidosis therapy is needed.Öğe The relationship of copper concentrations in feed and plasma to developmental orthopedic disease in foals(UNIV ZAGREB VET FACULTY, 2016) Coskun, Alparslan; Ozdemir, Ozgur; Erol, Muharrem; Kirbiyik, HayrettinThe study group consisted of ten foals, 3-6 months old, 6 male and 4 female, KWPN breed, with developmental orthopedic disease (DOD). The control group consisted of eight healthy foals. On clinical examination, lameness, swelling of joints, and pain were observed in all foals. Clinical, radiographic, and pathological findings in ten foals indicated DOD. Serum Cu concentrations in foals with DOD were significantly lower than in the control group (0.094 +/- 0.011 mg/kg vs, 0.932 +/- 0.068 mg/kg, respectively; P<0.05). Serum Zn levels (1.828 +/- 0.180 mg/kg vs. 0.9257 +/- 0.052 mg/kg, respectively, P>0.05), serum Ca levels (187.836 +/- 7.921 mu g/dL vs. 150.912 +/- 5.271 mu g/dL, respectively, P>0.05), and serum P levels (247.339 +/- 10.729 mu g/dL vs. 190.470 +/- 5.775 mu g/dL, respectively, P>0.05) were observed both in foals with DOD and in healthy foals. There were no statistically significant differences between the DOD group and the control group with respect to serum levels of Ca, P and Zn. We concluded that DOD is associated with reduced serum levels of Cu in foals. Copper is an important trace element for growing foals.Öğe Serosurveillance of&IT Neospora caninum&IT and &ITBrucella&IT species in Dairy Cattle of Konya, Turkey(FRIENDS SCIENCE PUBL, 2018) Ekici, Ozlem Derinbay; Isik, Nermin; Sayin, Zafer; Coskun, Alparslan; Sajid, Muhammad SohailThis study reports the seroprevalence of Neospora (N.) caninum and Brucella sp. in aborting and non-aborting daily cattle in Konya province of Turkey. To this end, blood samples were collected from 560 cattle, 66 of which were not aborting and 494 were aborting, and sera were isolated from these samples through standard protocol. Antibodies against N. caninum were determined by using a commercial competitive ELISA (cELISA) kit. Brucella sp. antibodies were determined using the Rose Bengal Plate Test (RBPT). According to cELISA results, 222 of 560 cattle (39.64%) were seropositive for N. caninum antibodies. Of 494 aborting cattle samples, 213 (43.11%) were positive for N. caninum antibodies. Through RBPT, 89 of the 560 cattle tested were positive for Brucella sp. Of 494 aborting cattle, 79 (15.99%) were positive for Brucella sp. The seropositivity differences between N. caninum and Brucella sp. were statistically significant in aborting cattle (p< 0.001). The co-infection rate of N. caninum seropositivity with B. abortus was detected 9.5% in aborting cattle. In conclusion, seroprevalence of neosporosis and Brucella sp. was 39.64% and 15.89% through cELISA and RBPT, respectively in cattle of Konya. (C) 2018 Friends Science PublishersÖğe Serum gastrin in dogs with acute or chronic gastritis and positive or negative for Helicobacter sp in the stomach(NATL VETERINARY RESEARCH INST, 2008) Guzelbektes, Hasan; Coskun, Alparslan; Ortatatli, Mustafa; Sen, IsmailThe relationship between gastrin levels and presence of Helicobacter-like organisms (HLO) in dogs with acute or chronic gastritis was investigated. For this purpose, a total of 52 crossbred Kangal Dogs aging 2-5 years were used; including 12 dogs with acute gastritis, 25 dogs with chronic gastritis, and 15 healthy dogs. Blood samples were collected from the vena cephalica. Serum gastrin levels were measured using commercial competitive binding radioimmunoassay. HLO were found in 64%, 58.3%, and 60% of animals with chronic gastritis or acute gastritis, and controls, respectively. The gastrin levels in dogs with chronic gastritis were higher than in those with acute gastritis and controls. There were no significant differences between the gastrin levels in all groups, with regard to HLO positive versus HLO negative dogs. In conclusion, HLO incidence was generally found in high levels in all the dogs. However, HLO did not primarily affect the stomach mucosal damage. In the mean time, there was no relation between the levels of serum gastrin in dogs with gastritis, either being HLO positive or negative. The results of the study showed that higher gastrin levels in dogs with gastritis were related to severe gastric lesions and mucosal damage.Öğe Therapeutic and prophylactic efficacy of imidocarb dipropionate on experimental Babesia ovis infection of lambs(ELSEVIER SCIENCE BV, 2007) Sevinc, Ferda; Turgut, Kursat; Sevinc, Mutlu; Ekici, Ozlem Derinbay; Coskun, Alparslan; Koc, Yilmaz; Erol, MuharremThe objective of this study was to evaluate the therapeutic and prophylactic efficacy of imidocarb dipropionate (IMDP) against babesiosis and to determine specific antibodies against Babesia ovis in experimentally infected lambs. Thirty-six 6-month-old splenectomized lambs were used. The lambs were randomly divided into six groups with six animals each, and were intravenously inoculated with 50 mL B. ovis-infected erythrocytes as follows: group I (therapy group) was treated with IMDP (1.2 mg/kg body weight) starting on the day of onset of clinical signs of babesiosis after the inoculation; group II (untreated control animals) was not treated with any therapeutic treatment after the inoculation; groups III, IV, V and VI (prophylaxis groups) were administered IMDP (2.4 mg/kg body weight) 1, 2, 3 and 4 weeks before the inoculation, respectively. The animals were housed in a tick-proof room with water and food ad libitum up to the 30th day post-inoculation (PI). The lambs were monitored from the first day PI by recording the manifestation of clinical disease, rectal temperature, and the degree of parasitaemia. All the lambs became infected with B. ovis, except five animals from group III, which were treated I week prior to experimental infection. Other animals showed signs of acute clinical babesiosis. The animals treated with IMDP (group I) were able to clear the parasite from the blood circulation after 48 h post-treatment. The recrudescence of B. ovis was observed in two lambs 7 days after treatment, and they were treated with the second similar dose of the drug. Six lambs (1, 1, 2 and 2 lambs in group III, IV, V and VI, respectively) from the prophylaxis groups died within 7-17 days after showing high parasitaemia and clinical symptoms of the disease. Regardless of the clinical symptoms, 83.30% and 66.66% of the lambs which were administered IMDP 1-2 and 3-4 weeks before, were determined to be protected against the virulent field strain of B. ovis.
