  • The porcine Aujeszky's disease was surveyed by Enzyme Immunodiffusion method and serologic neutralization test to the slaughtered pigs at slaughtehouse only in Seoul from March, 1990 to October, 1993. After detecting the positive by enzyme immunodiffusion method primary, we decided finally the positive by serologic neutralization test secondary. Results obtained through the experiments were summarized as followed; 1. The positive of Aujeszky's disease in March, 1990 was 2 of 1,000 sera. 2 positive were decided as the consigned pigs in Kalsan, Hongsung, Chungnaa 2. The positive of Aujezsky's disease in May, 1991 was decided 1 serum at Pogok, Yongin, Kyeonggi. 3. All of the positive detected by Enzyme immunodiffusion Method in 1993 were decided finally in the negative sera. 4. The positive sera detected in 1992 were decided 32 sera at Gyeonggi, 6 at Chungnam, and 1 at Gangwon. Especially, the positive sera percentage detected by Kit Latex Aujeszky Test appeared 78.04% at Gyonggi and by enzyme immunodiffusion Method appeared 11.11% at Chungnam and Gangwon.

  • A stochastic simulation model incorporated with Reed-Frost approach was derived for evaluating diagnostic performance of a test used for a screening program of an infectious disease. The Reed-Frost model was used to characterize the within-herd spread of the disease using a hypothetical example. Specifically, simulation model was aimed to estimate the number infected animals in an infected herd, in which imperfect serologic tests are performed on samples taken from herds and to illustrate better interpreting survey results at herd-level when uncertainty inevitably exists. From a risk analysis point of view, model output could be appropriate in developing economic impact assessment models requiring probabilistic estimates of herd-level performance in susceptible populations. The authors emphasize the importance of knowing the herd-level diagnostic performance, especially in performing emergency surveys in which immediate control measures should be taken following the survey. In this context this model could be used in evaluating efficacy of a survey program and monitoring infection status in the area concerned.

  • Several outbreaks of Getah virus (GETV) have been reported in horses and pigs, causing large economic losses. However, there have been no reports describing serological survey for GETV in South Korea pigs. The present study conducted serological survey of GETV in South Korean pigs. A total of 670 whole blood samples were collected from domestic pigs. The overall seropositive rate was 26.4%, higher than the rates observed in racehorses in 2013-2014. Preparations for epidemics of novel diseases caused by climate change should include regular serological survey for these diseases, including GETV, and the development of vaccines against novel pathogens.

  • A total of 710 bovine serum samples which are composed 532 bovine serum samples showed negative reaction and 178 bovine serum samples showed positive reaction with tube agglutination test (TAT) from North area of Gyeong-nam, Korea were tested using all the 3 assays which are Rose-Bengal test(RBT), tube agglutination test (TAT) and enzyme-linked immunosorbent assay (ELISA, two types) and analyzed for evaluation of specificity, sensitivity, reproducibility and predictive value. In the comparison of serum antibody titer agglutination test, RBT showed almost agreement with TAT. In the comparison of TAT and two types of ELISA method, they showed difference in specificity and sensitivity about 5%. But there is no significant difference in detecting sensitivity between two types of ELISA method and TAT. In serologic tests for bovine brucellosis, the new assay ELISA would be a good candidate for serologic survey for bovine brucellosis in Korea because it is efficient in detecting many test samples quickly. But the serum agglutination tests (RBT, TAT) are more economical and easy assay for detection. In the test of comparison of antibody titer between first day of finding and 10 days after finding by TAT, there was no change in 55% (76/139) of positive cattle.

  • A novel enzyme linked immunosorbent assay (ELISA) is described and compared with other established serologic tests for bovine brucellosis, namely the rose bengal test (RBT), the complement fixation test (CFT), and the tube agglutination test (TAT) approved and used in Korea. A total of 109 bovine serum samples were tested using all the 4 assays and analyzed as to specificity, sensitivity, reproducibility and predictive value. The ELISA showed 100% agreement with the CFT. The least agreement between ELISA was observed with the TAT. The agreement between the ELISA and RBT was not significantly different from that observed between the CFT and the ELISA. It is concluded that the new assay would be a good candidate for routine serologic survey for brucellosis in Korea. A protocol combining the ELISA and the CFT would increase the power for detection of serologically positive individuals and herds.

  • Deer can be one of the susceptible animals to bovine infectious diseases, and thus, may play a role either as a reservoir or amplifier host for spreading the diseases to other species such as cattle and goat. This study was conducted to determine the serum antibodies to bacterial infectious diseases for brucellosis, tuberculosis (TB), paratuberculosis (Johne's disease) in deer. Serum samples were randomly collected from 78 deer from 31 farms at Jeonbuk province, and 7 wild water deer from Jeonbuk wild animal treatment center during 2005 to 2007, respectively. Four farm deer (5.1%) showed antibodies to tuberculosis using Antigen Rapid Bovine TB Ab Test Kit. One elk (1.3%) and one wild water deer had antibodies for paratuberculosis. Antibody against Brucellosis was not detected in tube agglutination test (TAT) and enzyme-linked immunosorbent assay (ELISA). These data suggest that caution should be applied to inspection of velvet, deer blood and meat for human consumption from deer because of zoonotic bacterial diseases in deer. In addition, farmed deer can be a transmissible host for zoonotic disease to diary or raising farm.

  • There are no published data on Gyeongokgo (GOK) safety or efficacy despite being commonly use. The Gyeongokgo (GOK) is commonly used in traditional Korean medicine to promote a health qi and blood, but their objective data was not sufficient in clinical field. To investigate the safety and efficacy of GOK with hematologic and serologic testing and the change of the quality of life in healthy individuals. Randomized, subject-assessor-blind, placebo-controlled, single-center pilot study Participants and Interventions 29 healthy volunteer subjects were randomly placed into the GOK group (n = 20) or placebo control group (n = 9) and instructed to take one treatment packet (GOK or placebo) twice daily for 4 weeks. Subjects were assessed using the Fatigue Severity Scale (FSS) and Short Form 36 Health Survey (SF-36) and underwent hematologic and serologic tests and body composition analysis. The FSS total score (p = 0.093) and SF-36 general health index (p = 0.002) were improved following treatment in the GOK group. Post-treatment thyroid-stimulating hormone levels were increased in the GOK group compared with pre-treatment levels (p = 0.0042). C-reactive protein levels decreased (p = 0.0256) in the GOK group compared with that the placebo group. In time-series tests, GOK did not affect post-prandial serum triglycerides, glucose, insulin, or C-peptide levels. Notably, elevations in serum fasting triglycerides at 2- (p = 0.0333) and 4-hours (p = 0.0414) post-prandial were lower than those in the placebo group. GOK reduced fatigue levels and did not significantly affect laboratory test results performed to measure safety, serum glucose, and lipid profiles. Post-meal triglyceride levels were effectively reduced with treatment.

  • Background: Herpes zoster is a common dermatologic disorder. However, it rarely occurs in children and adolescents in Gwangju-Jeonnam province. Objective: This study aimed to analyze the epidemiological features and clinical characteristics of herpes zoster in children and adolescents. Methods: A retrospective survey was conducted on patients who visited the department of dermatology of Chosun University Hospital in Gwangju-Jeonnam province within the past 8 years. The medical records of 103 patients aged <18 years were reviewed. We analyzed for age, gender, accompanying symptoms, dermatomal distribution, underlying disease, treatment, and complications with serologic test. Results: The male-to-female ratio of the participants was 1.08:1, and their mean age was 13.0 years. Underlying diseases were observed in 3% (3/102) of the patients. The most common dermatomal distribution was thoracic dermatome (34%), followed by trigeminal (26%), cervical (20%), lumbar (15%), and non-skin (6%). The most common accompanying symptoms were headache (10%), fever (3%), and myalgia (3%). No difference was observed between patients who were varicella-zoster virus (VZV) IgM-positive and those who were VZV IgM-negative in terms of dermatome, visual analogue scale (VAS), severity, and body mass index (BMI). Conclusion: In children and adolescents with herpes zoster, the gender ratio and dermatomal distribution were similar to those previously reported, except for the low rate of underlying diseases. The incidence of herpes zoster in children was not significantly associated with immunosuppression and underlying diseases. Higher VZV IgM titer was not associated with dermatomal distribution, higher VAS score, or BMI. This study first compared the serological test results of children.

  • This study is aimed at offering basic data about prevention of Hepatitis B virus and infection control to dental hygiene students who will work mostly at dental offices which are characteristically exposed to a high risk of HBV infection. For this study, surveyed were 188 sophomores and juniors of the dental hygiene department who volunteered to undergo the tests of HBsAg and HBsAb. The examination of the blood collected from the samples and analysis of their perception about hygiene resulted in following conclusion: Positive HBsAg Four was found in 4 testees(2.1%) while 118(62.8%) revealed positive HBsAb. Juniors showed higher positive rate in HBsAg whereas sophomores had higher positive rate in HBsAb. But such difference has statistically no significance. Generally, students seemed to pay little attention to HBV, judging from the survey of their perception about the present state of HBsAg and HBsAb(p>0.05), conduct of infection(p<0.05), completion of 3 requested vaccinations(p>0.05), and formation of antibody(p>0.05). With regard to the infection routes of HBV, most students(92.4%) replied "through blood", which is statistically insignificant, though. Next ratio goes to the reply "through contaminated injectors". This reply came more from sophomores than from juniors, a difference which is statistically significant(p<0.05). The lowest rate of possible infection(29.2%) was thought to be "through breast-feeding of a positive mother"(p<0.05). In general, it turned out that sophomores had more knowledge about the infection routes of HBV than juniors. In terms of clinical history among family members, 6(3.1%) reported that some of their family members are currently suffering from a liver complaint, 3(1.6%) replied their family members were once afflicted, and 4(2.1%) said their members died of hepatitis. Except 10(4.7%), all the surveyees replied that their states of health are better than normal. Generally, sophomores are healthier than juniors except for the very health case, a difference which is statistically of no value.
