Pesticides are extensively used for the control of crop pests in agriculture and forestry. Organophosphate (OP) and carbamate pesticides are especially effective for the control of a variety of harmful insects. However, these cholinesterase inhibitors are also dangerous to non-target organisms (wildlife and other animals) because of their high acute toxicity. Most poisonings by pesticides occur as a result of misuse or accidental exposure, but intentional killing of unwanted animals also occurs. At the request of a local autonomous entity, we investigated wild bird poisonings by pesticides from 2003 to 2007. The 207 suspicious samples of pesticide poisoning based on the necropsy were analyzed by GC/NPD, GC/FPD, or GC/MSD. We looked for trends in the identification of pesticides in wild birds thought to have died from poisoning. Pesticides were determined in 59% of the total samples analyzed. Phosphamidon and monochrotophos were the most common pesticides identified, which amounted to 77% of the subtotal. Other OP and carbamate pesticides were also found in various concentrations from dead wild birds. The determined rates of pesticides were as high as 86% and 76% in 2003 and 2006, respectively, during an outbreak of avian influenza in Korea.

We report here two cases of Rhodococcus (R.) equi-causing pneumonia of Throughbred foals in Gyeonggi-do in 2006. R. equi was isolated from the lung lesions of the dead foals, and from the feces and soils on the farms where the clinical cases of R. equi infection occurred. The isolates were characterized by biochemical properties, polymerase chain reaction for vapA gene and antimicrobial susceptibility. In drug susceptibility test, erythromycin, gentamycin, vancomycin, and rifampin were found to be the most susceptible for all isolates. These results suggest that R. equi pneumonia may be endemic in the horse-breeding farms in inland Korea and the farm environment may be widely contaminated with virulent R. equi.

This study was conducted to investigate biochemical properties and O group serotypes of pathogenic 203 Escherichia (E.) coli isolates from poultry with collibacillosis in Korea during the period from April 2003 to December 2005. Biochemical and fermentative properties of 203 isolates of E. coli tested were in accordance with Cowan and Steel's classification standard. One hundred and forty one isolates (69.5%) could be classified into a total of 20 O serotypes. Among them, the predominant O groups were O78 (32.5%), O88 (7.8%), O15 (6.8%), O141 (6.4%), and O158 (3.0%) in decreased order. Other infrequently encountered serogroups included : O8 (2%), O161 (2%), O20 (1.5%), O125 (1.5%), O2 (1%). And O6, O18, O24, O46, O76, O109, O119, O138, O139 and O148 had a frequency of 0.5%, respectively. Sixty two isolates (30.5%) were non-typeable with standard 173 O antisera used in this study.

Newcastle disease virus (NDV) is the causative agent of a highly contagious and devastating Newcastle disease of poultry. A NDV (isolate DK1/07) was isolated from apparently healthy wild spot-billed ducks (Anas poecilorhyncha) captured at upper branch of the SapGyo Creek in Chungbuk province, Korea during early 2007. The DK1/07 isolate of minimum chicken embryo lethal dose killed all SPF chicken embryos within 60 h. The cleavage site of the F protein possessed the amino acid sequence
, which is a motif characteristic of virulent NDV strains. The F protein-based phylogenetic analysis revealed that the DK1/07 duck isolate was included in the cluster of genotype VIId and most closely related to recent NDV isolates obtained from chicken farms in Korea. Epidemiological importance of virulent NDV from wild duck is discussed.

Many neurotoxigenic clostridia are found in soil. Among animals, birds are especially susceptible to botulism, perhaps because they feed on insects, invertebrate carcasses, and decayed feeds contaminated with spores of Clostridium (C.) botulinum. C. botulinum type C is mainly involved in avian botulism. In the summer of 2005, death of a mute swan (cygnus olor) living in the pond of large bird cage was found in Seoul Grand Park Zoo. The birds presented presumptive clinical signs of botulism, such as ruffled hackle feathers, abnormal posture of the head, weakness, and flaccid paralysis. At that time, pond water in the breeding facilities was drained for 7 days, but there were still remained water containing sediment of feed and feces. Therefore, botulism was suspected and an experimentation were made to detect C. botulinum in the dead mute swan. Gross post-mortem findings of a mute swan showed jelly-like hemorrhagic contents in the intestine, sands and vegetations in the stomach. C. botulinum was isolated from the liver, small intestine and large intestine samples. Botulism was also confirmed by mouse inoculation test with the organ samples. With PCR, a gene encoding C. botulinum type C toxin was detected for the several organs of the mute swan died. These results suggested that death of mute swan was caused by C. botulinum type C.

Lactic acid bacteria have been reported their beneficial roles on host including reduction of infectious diarrhea problems. In this study, preventive effect of Lactobacillus (L.) reuteri HY25101 and L. johnsonii HY25103 on porcine epidemic diarrhea virus (PEDV) was investigated in suckling piglets. Two groups of one day old PEDV naïve piglets were orally administered L. reuteri HY25101 and L. johnsonii HY25103 for three days respectively before challenge with lethal dose of PEDV. In second experiment, passive immunized one day old piglets using colostrums containing PEDV specific IgA were used. The survival rates of the L. reuteri HY25101 administered group were significantly higher than that of L. johnsonii HY25103 administered group and viral shedding was rapidly diminished in L. reuteri HY25101 administered group. Interestingly piglets born from the sow immunized with attenuated PEDV vaccine were not completely protected from PEDV challenge, however coadministeration of L. reuteri HY25101 and colostrums containing PEDV specific IgA were more effectively prevent PEDV infection. These results suggested that dietary treatment using L. reuteri HY25101 could reduce diarrheal problem and mortality rate caused by PEDV in suckling pigs. In addition, L. reuteri HY25101 could be used as one of effective compensation treatment with attenuated live vaccine for PED.

Parallux, a solid-phase fluorescence immunoassay (SPFIA) developed for detection antibiotics residue in milk, was applied for analysis of antibiotics in muscle tissue of olive flounder (Paralichthys olivaceus), rockfish (Sebastes schlegeli), and red sea bream (Pagrus major). Fishes were dipped in neomycin 140 mg/ton water, the recommended therapeutic dose, for 24 h. Muscle samples were obtained on 1st, 2nd, 3rd, 4th and 5th day after drug treatment. The concentration of neomycin in muscle was determined using an internal standard (100 ppb as neomycin). The absorbance ratio of sample to internal standard (S/C) was employed as an index to determine the muscle residues in fishes. To investigate the recovery rate, the standard solutions were added to muscle samples to give final concentrations in muscle of 0.2 and 0.5 mg/ml. The recovery rates of all spiked samples were > 85% of the spiked value. Neomycin was detected in muscles of fishes treated after the 1st day of withdrawal period. On the 2nd day after drug treatment, all muscle samples showed negative reaction (S/C ration
1.0). The present study showed that the SPFIA can be applied for predicting residues of neomycin in muscle tissues of farmed fishes.

Comparative studies of histopathologic lesions from 23 purified protein derivative (PPD) positive cattle, 21 slaughter cattle found with tuberculosis, and 11 tuberculosis-positive elk (Cervus elaphus) were performed. PPD positive cattle did not show specific histopathologic lesions in all 23 heads that were no visible lesion reactor. Slaughter cattle found with tuberculosis revealed microscopically classical granulomatous lesion (tubercle) with central caseous necrosis surrounded by mantle of epithelioid cells and Langhan's giant cells capsuled by connective tissue in lung. Elk was noted with some different lesion patterns with classical granulomatous lesion and suppurative abscesses that was composed of fibrin, degenerated cells without having connective tissue. In addition, many Langhan's giant cells infiltration in alveoli at peripheral lesion were observed in some cases of classical granulomatous lesion and suppurative abscesses.

Eosinophilic myositis lesions are characterized by severe eosinophil infiltration along muscles of affected animals. The exact cause of the lesion remains controversial and the carcass is condemned once this lesion is seen during meat inspection. A cow slaughtered in Chonbuk province, Korea was observed to have disseminated pale foci throughout the musculature; meat samples were obtained and macroscopically investigated. Cut ends of neck and thigh muscle tissues showed variably sized, multifocal pale white-grayish nodular lesions. Histopathological examination consistently revealed inflammatory lesions with adjacent infiltration of eosinophilic granulocytes and focal necrotic calcification. However, no parasites, including Sarcocystis sp., could be discerned in the affected carcass. This case was diagnosed as idiopathic eosinophilic myositis in cattle.

This study was performed to detect Neospora caninum in blood of 61 Korean native cattle and 50 dairy cows in Chungnam province. All of them were healthy and did not show any clinical signs. DNA was isolated from blood samples and a 328 bp fragment was amplified by PCR using primer pair Np21 and Np6. The PCR positive rate was 14.8% in Korean native cattle and 0% in dairy cows. Cows with 15.6% were a little higher than bulls with 12.5% in gender. The detection rate of over 3-year-old Korean native cattle was 28.6% in age. The results demonstrate that N. caninum DNA can be detected in blood by PCR. PCR analysis in blood may be useful to annually screening test for N. caninum infection in clinically healthy cattle.

Plasmodium spp. in domestic and wild birds are microscopic, intracellular parasitic protozoa within the blood cells and tissues cause avian malaria. A 17-month-old Magellan penguin (Spheniscus magellanicus) with a clinical signs of anorexia, depression, and respiratory distress for 3 days was submitted to the Pathology Department of Veterinary Medicine, Cheju National University in October 2005. It was born and reared in the Jeju Island. Grossly, the liver was enlarged, pale and friable. The spleen was also enlarged with dark red coloration and friable. Histopathologically, the lesions in the liver were characterized by multifocal infiltration of macrophages and lymphocytes especially in perivascular regions. The schizonts of Plasmodium spp. contained up to 30 merozoites were found in numerous infiltrated mononuclear cells. Similarly, histiocytic cells were proliferated in red pulp of spleen and the schizonts were found in these cells. Numerous dark brown pigments were widely distributed in the liver and spleen. The result of the nested polymerase chain reaction clarified the causative agent of this case was Plasmodium spp.. This is the first report for the outbreak of avian malaria caused by Plasmodium spp. in a penguin that was born and reared in Jeju Island in Korea.

A 3-year-old spayed female Persian feline with non regenerative anemia showed persistent autoagglutination in EDTA anticoagulated blood. Primary immune-mediated hemolytic anemia (IMHA) was suspected and the underlying causes for IMHA were excluded by radiologic, sonographic, serologic and molecular studies. Cytologic examination of the bone marrow revealed that dysmyelopoiesis and dysplastic changes were prominent in the erythroid cells. These changes included asynchronous maturation of the nucleus and cytoplasm, binucleation, trinucleation, fragmented or lobulated nuclei and multilineages. Mild dysgranulopoiesis and dysmegakaryocytopoiesis were also detected including pseudo Pelger-Huet anomalies, giant band neutrophils, asynchronous maturation of the nucleus and cytoplasm in granulopoiesis and large hypolobulated forms as well as dwarf megakaryocytes in megakaryocytopoiesis. Myelodysplastic syndrome and congenital dysmyelopoiesis was ruled out by the low number of blast cells. Finally, secondary dysmyelopoiesis associated with IMHA was diagnosed and immunosuppressive treatment was successfully responsive.

A four-month-old intact femlae Abyssinian cat was present for routine health evaluation, because her littermate was recently died of ventricular septal defect. Diagnostic imaging studies showed a large caudal paracardiac mass in thoracic radiography and homogenous mass adjacent to heart in the echocardiography. Further echographic study revealed that the mass was liver and the diaphragmatic line was intact. The positive contrast celiogram revealed that no extravasation of the contrast media across the diaphragm and the prolapse of diaphragm into the pleural cavity. Based on our diagnostic imaging studies, the case was diagnosed as diaphragmatic deformity in a cat mimicking a cardiac mass.

A 2-year-old, female, Maltese dog (3.2 kg of body weight) was referred to the Veterinary Medical Teaching Hospital, Chungnam National University with vomiting, anorexia and depression. Twelve hours prior to the onset of clinical signs, the dog ingested some grape skins (about 60 g). Physical examination at the time of presentation showed peripheral edema and mucous pallor. Blood and blood chemical analysis revealed anemia and moderate azotemia with elevated blood urea nitrogen (107.2 mg/dl), creatinine (6.3 mg/dl) and hyperphosphatemia (11.3 mg/dl). Echogenicity of renal cortex were observred by ultrasonography. The dog was diagnosed as acute renal failure occurred by grape skin toxicosis. The dog was treated with supportive care such as fluid therapy, diuretics (furosemide) and phosphorus binder (almagate). A normal condition of blood and blood chemical findings and clinical signs was observed at five days after treatment, and prognosis is good to date.

We report the electrocution of Korean native cattle by a fallen electric wire, which caused the death of thirteen animals. The owner of the cattle felt an electric shock on touching the steel pen and found a fallen 220-V wire on the roof of the barn; additionally, the roof was singed. Clinically, the animals developed spasm, difficulty breathing, and excessive salivation. Histopathologically, many visceral organs revealed severe congestion or hemorrhage, which is consistent with previous reports. This study revealed that the proper installation of electric wires on farms is essential to prevent economic loss by electrocution.

A six-year-old, female Jin-do dog was referred for the recurrence of vaginal prolapse. Less than 7 months previously, the dog with the vaginal prolapse had been treated with hormone therapy because ultrasonography had identified a single follicular cyst in the left ovary. Three months after the first visit, the dog came into heat and the vaginal prolapse recurred. Ultrasonography showed multiple follicular cysts in both ovaries and radioimmunoassay detected a plasma estradiol-
concentration of 13.3 pg/ml. Treatment involved the repositioning of the vaginal prolapsed, ovariohysterectomy and the resection of the protruding tissue. The dog had been completely recovered two months later after the treatment.

Portosystemic shunt (PSS) was diagnosed in 43 dogs by mesenteric portogram from January, 2002 to June 2007 in Haemaru referral animal hospital. PSS was found in various breeds including Maltese, Miniature Schnauzer and Yorkshire Terrier and there was no predisposition in gender. In laboratory parameters, mean cell volume was lower than normal value in single shunt and alanine aminotransferase was higher than normal range in multiple shunts with clinical significance. Cystic calculi were found in over 50% dogs with PSS and even in 70.8% dogs with single shunt. In 81% dogs with PSS, extrahepatic single shunt such as portocarval type and portoazygous type was identified. Extrahepatic multiple shunt and intrahepatic single shunt were observed in 4 dogs, respectively. Gradual attenuation using ameroid constrictor was applied to 35 dogs with extrahepatic single shunt and the prognosis of these dogs were good except two dogs, which showed poor prognosis because of acquired multiple PSS and renal disease unrelated with PSS, respectively.

This study describes thoracic radiographic features of normal premature minipigs at the age of 4, 8, 12 and 20 weeks. The evaluation for appearance, shape, contour, location and extent of distribution of thoracic organs was recorded through right lateral and ventrodorsal thoracic radiographs. The size of the tracheal diameter, cranial mediastinum, and the heart were measured, and information about the correlation of each organ in their thoracic conformation could be obtained. Although there were limitations with plain thoracic radiographs, basic characteristics and data for thoracic radiographs of normal premature minipigs according to each age were useful.
