  Abstract : This study aimed to evaluate the feasibility of percutaneous endoscopic foraminotomy (PEF) for the treatment of intervertebral disc herniation of the thoracolumbar spine in large-breed dogs by comparing it with open hemilaminectomy (OH). Six large-breed canine cadavers were used in the present study. A barium and agarose mixture (BA-gel) simulating intervertebral disc herniation was injected into the spinal canal at two intervertebral spaces (T12-T13, L2-L3) of the thoracolumbar spine in each cadaver. PEF and OH were randomly allocated to the sites in each cadaver. Computed tomography was performed pre- and postoperatively. The incision length, vertebral window size, procedure time, and amount of simulated disc material removed were recorded to compare PEF and OH. Both procedures clearly exposed the simulated disc material and spinal cord. The size of the incision and vertebral window created after PEF was much smaller than those after OH. The surgical duration of PEF was longer than that of OH. However, no significant difference (P>0.05) was observed in the amount of BA-gel removed between PEF and OH. Thus, PEF could be used as an effective surgical option for intervertebral disc herniation of the thoracolumbar region in large-breed dogs in that it could lead to less tissue damage as well as sufficient removal of the simulated disc material.

  Abstract : Bovine viral diarrhea virus (BVDV) is distributed in cattle worldwide and causes significant economic losses to the livestock industry. Identification and remove of BVDV persistently infected (PI) cattle is very important to control BVDV infection in cattle herd. The objective of this study is to investigate the infection status of BVDV infection in Korean native cattle (Bos taurus coreanae) farms located in Jeonbuk State. From 2021 to 2022, a total of 1,497 samples were collected from 17 cattle farms and tested for BVDV antigen using a commercial ELISA kit. By the first ELISA testing, 24 cattle from six farms were positive for BVDV antigen, showing the farm-level or cattle-level prevalence of 35.3% or 1.6%, respectively. By the second ELISA testing which carried out with the first ELISA-positive samples after three-weeks, 12 cattle (0.8%) from five farms (29.4%) were positive for BVDV antigen, indicating these cattle were PI cattle. Genotypes of BVDV were determined with 12 BVDV-positive samples using a previously described RT-PCR assay and the results showed that 3 (25.0%) and 9 (75.0%) were confirmed to be type 1 and type 2, respectively. These results will be helpful to establish the effective control strategy for BVDV in cattle farms in Jeonbuk State.

  Abstract : From July to December 2022, we investigated the incidence of enteric pathogens causing diarrhea in calves under 100 days old at 22 farms across Korea. A total of 354 calves (including 247 dairy calves and 107 Korean native calves) were included. We used commercially available rapid diagnostic kits to identify five enteric pathogens, including bovine rotavirus (BRV), bovine coronavirus (BCoV), Cryptosporidium. Escherichia coli (E. coli), and Giardia. This study investigated how factors such as age, season, and birth month, which can influence the incidence of intestinal pathogens, affect the incidence of these pathogens in diarrheic dairy calves and Korean native calves. Our study found that the incidence of diarrhea-causing pathogens differed between dairy and Korean native calves. In diarrheic dairy calves, bovine rotavirus (BRV) incidence rates, correlated with season and birth month. Similarly, Cryptosporidium incidence C were associated with age and season, while Giardia incidence rates varied by season and birth month. Korean native calves, on the other hand, exhibited seasonal and birth month-related variations in BRV incidence rates, with Cryptosporidium incidence rates influenced by birth month.

  Abstract : A 5-year-old spayed female mixed-breed dog, previously receiving 7 months of immunosuppressive therapy for pemphigus foliaceus, presented to our referral hospital with a history of dog bites on the right forelimb, chest, and flank 4 days prior to presentation. Physical examination revealed a rectal temperature of 38.6℃; heart rate of 130 beats per minute; panting; systolic blood pressure of 60 mmHg; and swelling, purulent discharge, warmth, pain, and lameness in the right forelimb. The laboratory investigation revealed neutropenia and elevated C-reactive protein levels. Suppurative neutrophilic infiltration with bacterial infection was detected by impression cytology of the pus on the right forelimb. Based on the results of the clinical examinations and laboratory tests, the dog was diagnosed with dog bite-induced sepsis with pemphigus. Meropenem and metronidazole were prescribed. Clinical signs, neutropenia, and C-reactive protein levels markedly improved after 5 days. Subsequently, pemphigus foliaceus relapsed in the dog, and it is currently undergoing re-administration of immunosuppressive medications. To the best of our knowledge, this is the first case report of successful management of dog bite-induced sepsis in a dog undergoing long-term immunosuppressive therapy.

  Abstract : An 11-year-old neutered male Dachshund dog weighing 7 kg presented with acute onset of respiratory distress after subcutaneous administration of cytosine arabinoside (CA). The patient previously diagnosed with meningoencephalitis of unknown origin and was being treated with oral prednisolone, levetiracetam, potassium bromide, gabapentin, and periodic subcutaneous CA administration (50 mg/m², q 12 h, subcutaneous, 4 times, every 3 weeks). The patient developed tachypnea with labored respiratory effort after 9th CA administration. Thoracic radiograph revealed bilateral diffuse interstitial to alveolar pulmonary opacities, and echocardiogram indicated no evidence of left-sided heart failure. Based on the onset coinciding with the administration of CA, low possibility of other pulmonary disease, remission of symptom showed after discontinuation of CA, we suspected CA-induced interstitial lung disease. The patient’s pulmonary opacities on the radiograph improved to a similar degree as before the adverse event over time, but respiratory symptoms were not fully resolved. Sildenafil (2 mg/kg, per oral, q 12 h) was given as therapeutic trial to manage possible pulmonary hypertension, suspected a sequela of the lung disease, based on an echocardiographic evidence and clinical signs. The patient’s respiratory symptom was well managed since, and achieved discontinuation of sildenafil.

  Abstract : Three dogs (7-year-old, neutered male Chihuahua; case 1, 1-year-old, spayed female mixed breed; case 2, 10-month-old, female Maltese; case 3) were referred to Jeju Veterinary Medicine Teaching Hospital for traumatic brain injury. All three patients exhibited abnormal neurological symptoms. The patients were diagnosed through medical history obtained from their caregivers and through computed tomography (CT) or magnetic resonance imaging (MRI) scans. Structural brain abnormalities were observed in two dogs through CT scans and in one dog through MRI. Decompression therapy with mannitol was administered to all three dogs. Case 1, which showed CT findings of pulmonary hemorrhage but no significant brain injury, and case 2, which had mild brain damage on CT imaging, showed improvement in neurological symptoms and gait abnormalities after decompression therapy. However, case 3, which showed suspected brain hemorrhage and brain edema on MRI, did not respond to decompression therapy and was euthanized one month later. Imaging evaluation through CT or MRI in dogs with traumatic brain injury can assist clinical veterinarians in assessing the prognosis of patients.

  Abstract : A broiler farm in Jeonbuk province experienced high mortality due to decreased feed intake and poor growth, and pathological evaluation of 11- and 17-day-old broilers was performed, which led to the diagnosis of runting-stunting syndrome. From the start of the rearing period to shipment, 18.4% of the chickens in the three barns experiencing continuous culling and mortality were affected, compared to 7.7% in the other five barns. Gross findings on the 11-day-old broiler chicken revealed proventricular dilatation and hemorrhage, intestinal hemorrhage, urate deposition in the pericardium and renal tubule, nephropathy, and mild hepatic capsulitis. Similar proventricular dilatation and hemorrhage were observed in the 17-day-old broiler chickens. In addition, hepatitis and pericarditis were observed with the progression of secondary bacterial infection, and pathogenic Escherichia coli was isolated from these lesions. As a result of PCR, Newcastle disease virus, fowl adenovirus, chicken anemia virus and Marek’s disease virus were not detected in the all tissue samples. In contrast, infectious bronchitis virus was detected in the proventriculus, kidney and cecal tonsil. chicken astrovirus was detected in the intestine, cecal tonsil and bursa of Fabricius, and chicken parvovirus was detected in proventriculus, intestine, cecal tonsil and bursa of Fabricius. By sharing the diagnostic process of a case of malabsorption syndrome through this case report, we hope that it can be widely utilized in the diagnostic process of livestock disease pathognomonic institutions.
