Lismarani, Annisa | Ratnasari, Dewi | Ridwan, Azwar
Otitis media is inflammation of part or all of the middle ear mucosa, Eustachian tube, mastoid antrum, and mastoid cells. Otitis media is less common in adults than in children and is more common in men. The clinical symptoms of AOM depend on the stage of the disease and the age of the patient. The purpose of this study was to determine the characteristics of patients with acute otitis media in the field of battle image clinic in 2020 based on gender, age, and clinical symptoms. This research was conducted by collecting data from medical records at the citra medan perjuangan clinic in 2020. Then the data was processed using a computer, and the results were analyzed descriptively by univariate analysis. The number of samples that have been collected is 72 people. The highest distribution was male sex at 61.1%, age 1-5 years at 61.1%, and fever at 58.3%. Further research is needed to determine the risk factors for AOM that can be used as prevention.

2021
Moon, M.Y. | Kim, J.Y. | Kim, H.J.
The goal of this study was to measure immunoglobulin G4 (IgG4) concentrations and to evaluate the significance of these values in the management of canine pancreatitis. The medical records of 24 dogs that visited the Veterinary Medical Teaching Hospital between December 2016 and June 2018 were retrospectively reviewed to identify dogs that had been diagnosed with pancreatitis. The serum C-reactive protein and serum IgG4 concentration in the affected dogs were highly increased compared to the healthy group. Particularly, serum IgG4 measured significantly higher in dogs with pancreatitis and concurrent immune-mediated disease (p < 0.05). In conclusion, increased serum IgG4 concentrations are a characteristic finding in dogs with pancreatitis. The results of this research indicate that an elevation in IgG4 has the potential of being used as a tool for the diagnosis of pancreatitis and concurrent immune-mediated disease.

Baek, S.H. | Nam, I.S.
The levels of aflatoxin (AFT) and ochratoxin (OCT) were assessed at different seasons in raw materials, different feed manufacture processing stages, and animal feeds in feed mills in Korea implementing the hazard analysis and critical control point (HACCP) system. Two hundred samples were collected in all four seasons from five feed mills implementing the HACCP system and examined for AFT and OCT contents. The AFT and OCT levels were analysed by using HPLC method to provide information on raw material and product stage. The AFT content of raw ingredients in the spring season was highest in corn gluten (3.84 ppb) and lowest in corn (1.82 ppb) The AFT content of corn was highest in the winter season (2.17 ppb). The content of OCT in wheat was highest in the winter season. The amounts of AFT and OCT at processing stages were higher than in the raw materials or feed. In particular, AFT content was higher in the transfer stage (3.88 ppb) than in the mixing (2.86 ppb) or filling stages (3.45 ppb) in the summer season. The means of AFT and OCT level in laying hen feed was 3.41 ppb and 1.14 ppb for broiler feed, respectively. The means of AFT and OCT level in and broiler feeds was 3.44 ppb and 1.17 ppb for broiler feed, respectively.

2021
Kim, D.H. | Han, H.J. | Kim, J.H.
A 5-year-old neutered female Dachshund dog presented with a 3-month history of hyperthermia, skin lesions, and shifting lameness. Based on physical examination, blood tests, urinalysis, and radiographs, the dog was diagnosed with systemic lupus erythematosus. Clinical signs improved after administration of prednisolone and cyclosporine but relapsed after the prednisolone was reduced due to side effects. Oral levamisole was commenced and the other immunosuppressants were tapered over a period of 2 months and then stopped. Levamisole was retained as the sole therapy for an additional 2 months. Six months after discontinuation of all treatment, the patient remained in remission.

Yang, D.K. | An, S.J. | Park, Y.S. | Yoo, J.Y. | Park, Y.R. | Park, J.W. | Kim, J.T. | Ahn, S.J. | Hyun, B.H.
Mammalian reovirus (MRV) causes respiratory and intestinal disease in mammals. Although MRV isolates have been reported to circulate in several animals, there are no reports on Korean MRV isolates from wildlife. We investigated the biological and molecular characteristics of Korean MRV isolates based on the nucleotide sequence of the segment 1 gene. In total, 144 swabs from wild animals were prepared for virus isolation. Based on virus isolation with specific cytopathic effects, indirect fluorescence assays, electron microscopy, and reverse transcription-polymerase chain reaction, only one isolate was confirmed to be MRV from a Korean roe deer (Capreolus pygargus). The isolate exhibited a hemagglutination activity level of 16 units with pig erythrocytes and had a maximum viral titer of 10⁵·⁷ 50% tissue culture infectious dose (TCID50)/mL in Vero cells at 5 days after inoculation. The nucleotide and amino-acid sequences of the partial segment S1 of the MReo2045 isolate were determined and compared with those of other MRV strains. The MReo2045 isolate had nucleotide sequences similar to MRV-3 and was most similar (96.1%) to the T3/Bat/Germany/342/08 strain, which was isolated in Germany in 2008. The MReo2045 isolate will be useful as an antigen for sero-epidemiological studies and developing diagnostic tools.

2021
Lee, Y.J. | Joo, H.G.
Biosilica is a silica-based substance derived from the cell walls (frustules) of diatoms. Recently, research into biosilica’s biological functions is underway, but little has been reported on the effects of biosilica on immune cells. In this study, we investigated the effect of ionized biosilica water (iBW) on dendritic cells (DCs), which play crucial roles as antigen (Ag)-presenting cells. Treatment with iBW increased the expression of immune response-related markers, closely connected to the maturation of DCs, and the production of tumor necrosis factor-alpha. In addition, iBW-treated DCs (iBW-DCs) had a lower uptake of fluorescein isothiocyanate-dextran than that of control DCs. Mixed leukocyte response analysis used for measuring the Ag-presenting capability of DCs, showed iBW-DCs had a higher capability than that of control DCs. Interestingly, DCs treated with lipopolysaccharide (LPS) and iBW had a lower level of Ag-presenting capability than that of LPS-treated DCs. Taken together, the results indicate that iBW alone can mature DCs, but it decreases the Ag-presenting capability of DCs in the presence of LPS, a representative agent of inflammation. This study may provide valuable information regarding the effect of iBW on immune cells. Further research is needed to investigate how iBW induces the observed biphasic immunomodulatory activity.

Altaif, K.I. | Mhaisen, F.T. | Mizhir, A.H.
The small intestine of two rallid aquatic birds (Fulica atra Linnaeus, 1758 and Gallinula chloropus (Linnaeus, 1758) from Bahr Al-Najaf depression, southwest of Al-Najaf city, mid-Iraq), were infected with the nematode Amidostomum acutum Seurat, 1918 with a prevalence of 25% and 50%, respectively, and a mean intensity of 24.5 and 30, respectively. The infected birds showed several gross pathological and microscopic lesions in their small intestine due to the infection with this nematode. The gross lesions included hypertrophy in the anterior part of the duodenum and small rough nodules on the small intestine wall. Microscopic lesions included necrosis and shortening of villi with their fullness with inflammatory cells, degeneration of villi, and an increased number of acini at the base of the intestinal villi.

Keskin, I. | Gürgen, D.G. | Avinca, D. | Özdemir, E.M. | Keskin, S.U. | Karabulut, S.
The axolotl has extraordinary regeneration capacity compared to other vertebrates. This remarkable potential has been attributed to its life-long neoteny, characterized by the exhibition of embryonic characteristics at the adult stage. A recent study provided a detailed morphological analysis of the sperm morphology of the Ambystoma mexicanum using routine and detailed histological techniques. The primary purpose of the present study is to describe a simple and inexpensive method for evaluating the morphology of axolotl sperm. In this study, spermatophore structures were collected and spread on slides and air-dried. The slides were stained with periodic acid Schiff, toluidine blue, Masson’s trichrome, Giemsa, Spermac, and Diff-Quik dye for a morphological examination. The slides were coated with gold/palladium for a scanning electron microscopy examination. The sperm of the axolotl consisted of an elongated head, a neck, and a flagellum covered with an undulating membrane. The lengths of the midpiece, tail, and head were 8.575 µm, 356.544 µm, and 103.661 µm, respectively. In the flagellum part, the wavy membrane structure, whose function has not been explained, surrounds the tail. The data obtained from this study will constitute an important step in designing future research on the reproductive and regeneration capacity of the axolotl.

Acinetobacter is a bacteria found in the environment and clinical specimens, causing nosocomial infection and antimicrobial resistance (AMR) threats. This study examined the prevalence, species, and AMR characteristics of Acinetobacter isolated from surgical practice and the laboratory dog husbandry room environments (n = 235) at Rajamangala University of Technology Tawan-ok veterinary hospital during 2018-2019. The prevalence of Acinetobacter in the laboratory dog husbandry room and veterinary belongings were 2.55% and 0.43%, respectively. Species determination was Acinetobacter hemolyticus (2.1%) and Acinetobacter baumannii (0.4%) from environments in the laboratory dog husbandry room, and Acinetobacter junii (0.4%) from the shoes used in the surgical practice room. AMR was observed in both study environments and the specimens sent to the Veterinary Diagnostic Center. These isolates had a high resistant percentage to amoxicillin-clavulanic acid (84.62%), sulfamethoxazole-trimethoprim (61.54%), and cephalexin (53.85%) but were susceptible to imipenem. Compared to the isolates recovered from the clinical specimens, most isolates derived from environments exhibited multidrug resistance and shared correlated resistance patterns. These results highlight the need for sanitization in the dog husbandry room. Furthermore, the AMR results can be used as a preliminary baseline for studying AMR Acinetobacter contamination in animals and their environments.
