In 2007, an outbreak of epizootic hemorrhagic disease (EHD) occurred in Turkey. On the basis of clinical investigation, 41 cattle were suspected to have EHD. Reverse transcription–PCR and sequence analyses indicated that the virus belonged to EHD virus serotype 6, thus confirming EHD virus infection of cattle in Turkey.

Serum total cholesterol and high-density lipoprotein cholesterol levels decreased, but serum triglyceride level increased in dogs with parvoviral enteritis. Low serum total cholesterol and high-density lipoprotein cholesterol levels may be used as an index of the severity of parvoviral enteritis.

In this study, the clinical findings and results of haematological and biochemical analyses of 26 cattle with botulism were evaluated. The most important clinical signs in the affected cattle included: decreased appetite, ataxia, difficulty to rise, loss of tongue tone, salivation and bradycardia. A definitive diagnosis of botulism was based on demonstration of the preformed toxin in ruminal and intestinal contents and feed materials including poultry litter, by mouse inoculation test. This study is the first confirmation, by direct toxin isolation, of Clostridium botulinum type C and Clostridium botulinum type D in cattle, in Turkey.

Thirty dehydrated diarrheic calves aged 2-45 days were used to study the effects of small volume intravenous 7.2% hypertonic saline and 6% dextran 70 solution in combination with alkalinising oral fluids and to compare this therapy with the large volume intravenous isotonic saline with alkalinising oral fluid treatment. This study included a total of 30 diarrhoeic dehydrated calves aged 2-45 days. After routine clinical and haematological examinations, the calves were allotted to two treatment groups. Isotonic saline solution (32 ml/kg, i.v.) with an oral electrolyte solution (22 ml/kg, p.o.) were administered to group I (control), and the combination of 7.2% hypertonic saline in 6% dextran 70 solutions (HSD) (4 ml/kg, i.v.) with an oral electrolyte solution (50 ml/kg, p.o.) were administered to group II (test). Additionally, an oral electrolyte solution (50 ml/kg, p.o.) was readministered to both groups at 12 h of the study. The clinical and haematological examinations of all calves were performed both before and after the treatment at the 1/2, 1, 2, 4, 12 and 24 h. The capillary refill time, peripheral pulse quality, dehydration degrees, mental status, haematocrit rates, haemoglobin and plasma values after treatment were found to be statistically different compared with the values before treatment. In comparison with group I, group II is observed to have shorter capillary refill time at 1, 4 and 12 h (P < 0.001) and better peripheral pulse quality at 1/2 (P < 0.05), 1, 2, 4 and 12 h (P < 0.001). Moreover, the degree of dehydration in group II, was significantly improved at 2 (P < 0.01), 4 and 12 h. Results of the study indicated that administration of low volumes of hypertonic sodium chloride and dextran 70 solution combinations with oral electrolyte solutions was concluded as quicker, practical, economical and most importantly an effective way for the treatment of dehydrated diarrhoeic calves.

Endotoxin is a potent stimulator of the inflammatory response and is believed to initiate the pathology in gram-negative sepsis. Agents are being searched for that bind and neutralize or block the effects of endotoxin. The aim was to study the anti-endotoxic effects of polymyxin-E (colistin) in endotoxaemic dogs. The study included a total of 30 endotoxaemic dogs, which were divided into two groups (control = 15; test = 15) of both sexes, different breeds and ages. Hetastarch colloid solution (Expahes,10 mL/kg, i.v.) with lactated Ringer's solution (20 mL/kg, i.v., Q12 h) was given to all dogs. While ampicillin was administered (Alfasilin, 10 mg/kg, i.m., Q12 h) as an antibacterial to the control group, colistin (12,500 IU/kg, i.m., Q12 h) + ampicillin were administered to the test group. The clinical examination (body temperature, pulse and respiration rates, capillary filling times, peripheral pulse qualities, dehydration degrees), hematological and biochemical examinations (WBC, RBC, HGB, HCT, thrombocyte, serum urea, creatinine and TNF-alpha) were performed both before the treatment, and 2, 4, 12 and 24 h after the treatment. In comparison with the control group, it was observed that test group had shorter capillary filling time at 24 h (P < 0.001). Moreover, the degree of dehydration in test group, was significantly improved at 24 h (P < 0.01). While the differences in peripheral pulse qualities significantly differed between 0 and 2 h in controls, at 2, 4, 24 h after treatment it was found to be significantly increased when compared with 0 h in the test group. Serum TNF-alpha concentrations were statistically decreased in the test group between 0 h and other times (P < 0.01). When compared with controls, serum TNF-alpha concentrations were lower at 2, 4, 12 and 24 h in test group (P < 0.05). Results of the study indicated that polymyxin-E (colistin) has an anti-endotoxic effect and is safe for the dogs with endotoxemia at the dosage used in this study.

Sentürk S., E. Özel, A. Sen: Clinical Efficacy of Rifampicin for Treatment of Canine Pyoderma. Acta Vet. Brno 2005, 74: 117-122. In this study, the efficacy and field safety of rifampicin were evaluated in dogs with pyoderma. Clinical diagnoses of canine pyoderma were supported by bacteriologic cultures. 20 dogs with pyoderma were treated with rifampicin at a dose of 5 mg·kg -1 once daily for 10 days. Staphylococcus intermedius (40%) was isolated as the predominant pathogen. Serum GGT, ALT, urea, creatinine levels were assessed both before and after treatment for hepatic and renal effects of rifampicin. However, these parameters after treatment were not found to be statistically different compared with the values before treatment. While treatment was clinically successful in 18/20 (90%) dogs with pyoderma, poor improvement was noted in 2/20 (10%) dogs. Rifampicin was safe and effective for the treatment of canine pyoderma at the dosage used in this study. Dog, urea, Rifamycin Staphylococcus intermedius,
