Because of the imminent market opening of livestock and poultry products, Korean poultry industry is faced an influx of contagious diseases from abroad. Due to the increasing trend of intensive and automatic poultry farming, the risks of catching various poultry epidemics are ever more increasing. For the prevention of poultry epidemics, the principles of biosecurity should be observed rather strictly. In addition, regular checking to confirm the presence or absence of latent diseases through serological test, post-mortem examination, and laboratory test, should be carried out routinely. Finally, all kinds of stress factors should be minimized to keep the flock healthy and productive, so that they can achieve their maximum genetic potential.

Background: Porcine epidemic diarrhea virus (PEDV) is a swine enteropathogenic coronavirus that has devastated the swine industry in South Korea over the last 30 years. The lack of an effective method to control the endemics has led to a surge in PEDV recurrences in affected farms throughout the country. Objectives: In the first step toward establishing systematic monitoring of and active control measures over the swine populations, we constructed an assessment model that evaluates the status of (1) biosecurity, (2) herd immunity, and (3) virus circulation in each of the PEDV-infected farms. Methods: A total of 13 farrow-to-finish pig farms with a history of acute PEDV infection on Jeju Island were chosen for this study. The potential risk of the recurrence in these farms was estimated through on-site data collection and laboratory examination. Results: Overall, the data indicated that a considerable number of the PEDV-infected farms had lax biosecurity, achieved incomplete protective immunity in the sows despite multi-dose vaccination, and served as incubators of the circulating virus; thus, they face an increased risk of recurrent outbreaks. Intriguingly, our results suggest that after an outbreak, a farm requires proactive tasks, including reinforcing biosecurity, conducting serological and virus monitoring to check the sows' immunity and to identify the animals exposed to PEDV, and improving the vaccination scheme and disinfection practices if needed. Conclusions: The present study highlights the significance of coordinated PEDV management in infected farms to reduce the risk of recurrence and further contribute towards the national eradication of PEDV.

The emergence of highly contagious viral diseases of livestock and poultry such as foot-and-mouth disease (FMD), African swine fever (ASF) and highly pathogenic influenza (HPAI) have necessitated the formulation of policies and regulatory frameworks for preventing ingress of exotic diseases and controlling dissemination of endemic diseases within the country. The disease control ratings to manage contagious livestock disease in farms have not being widely used because the evaluation parameters were not being considered inappropriate. The purpose of this study was to reinforce the validity of the parameters for evaluation factors and the objectivity of the scoring criteria in the application of the current disease management rating system. The diseases subject to intensive management were improved by reflecting farm situation. For the evaluation based on the disease grading system of farms, the diseases subject to intensive management were realized, the list of diseases for evaluating the vaccination rate was revised, and the quarantine and sanitation management standards were revised. The effectiveness of the improved livestock disease management system was confirmed through the application of actual pig farms. Therefore, this system will be used as a means to evaluation the biosecurity at the farm units. Through this, it will contribute to establish effective biosecurity measures for each farm by improving and supplementing the present disease grading system.

일반적으로 고병원성 조류인플루엔자(HPAI; highly pathogenic avian influenza)가 발생을 하면 일정한 방역지역을 선정하여 그 범위 내의 농장에 대해서는 일괄적 살처분을 진행한다. 그러나 이러한 살처분은 산업에 막대한 경제적 손실을 줄 수 있지만, 방역 범위를 줄이게 되면 수평전파의 위험성이 커지게 된다. 따라서 본 연구에서는 국내 가금농장의 차단 방역 수준과 HPAI 발생 위험도를 측정할 수 있는 방법을 마련하고, HPAI가 발생 시 방역지역에 포함된 농장들을 선별적으로 살처분을 할 수 있는 방안을 마련하고자 수행하였다. 국내 가금농장의 계종, 규모, 지역에 따라 전국적으로 8개의 농장을 선정하였으며, 일반관리 51항목, 방역관리 106항목, 위생관리 26항목으로 총 183 항목으로 나누어 차단 방역 수준을 평가하였다. 전반적으로 산란계 농장인 5개 농장(JS, GE, CS, HS, OE)이 복지농장 (CH), 육계농장(JG, LB)보다 종합적으로 높은 수준의 점수를 획득하였다. 산란계 농장은 대부분 130점에서 157점 사이에 있는 반면, 육계농장은 45점과 75점이었으며, 복지농장은 70점 수준으로 농장간 차단 방역 수준 편차가 심하였다. 평상시 가금농장의 HPAI 발생의 위험도도 일반관리, 방역 관리, 위생관리로 나누어 평가한 후 기존의 각 농장별 현재의 차단 방역수준과 서로 비교하였다. 현재의 차단 방역 수준이 HPAI 발생 위험도보다 높은 수준의 농장의 경우 대부분이 3개 관리 분야 중 방역 관리가 뛰어나다는 공통점이 있었으며, HPAI 발생 위험도가 현재의 차단 방역 수준을 능가하는 경우에는 대부분 3개 분야의 관리가 전반적으로 취약하였지만, 특히 방역 관리수준이 매우 낮은 점수를 취득하였다. 이와 같이 본 연구에서 제시한 가금농장의 차단 방역 수준 평가를 위한 항목들을 활용을 하면 현재 가금농장의 차단 방역 수준을 평가할 수 있을 뿐 아니라, HPAI 발생에 대한 위험도를 추정할 수 있다. 따라서, 이러한 위험도 평가를 HPAI 발생시 방역 지역 내 농장에 다른 요소들과 함께 적용을 한다면 선택적 살처분의 가능성도 높아질 것으로 판단된다.

Low-value fish is the most commonly used feed in Asian fish farms despite the fact that its application is controversial in regard to the sustainability and biosecurity of aquaculture. In this study, the causal agent of a disease outbreak at a Korean rockfish Sebastes schlegeli farm was investigated to determine whether the low-value fish used at the farm was the source. Infected Korean rockfish and Pacific sand eel used as feed were sampled from the farm, and bacterial cultures recovered from the internal organs of all sampled rockfish were isolated as pure cultures and later identified as Vibrio harveyi. The causal agent of the disease was also isolated from the kidneys of some of the sampled Pacific sand eels. This study provides additional evidence that the low-value fish used as feed at fish farms can be a key source of infectious diseases.

Pollination is an essential process for plants to carry on their generation. Pollination is carried out in various ways depending on the type of plant species. Among them, pollination by insect pollinator accounts for the most common. However, these pollinators have be decreasing in population density due to environmental factors. Therefore, use of artificial pollination is increasing. However, there is a lack of information on microorganisms present in the artificial pollens. We showed the composition of bacteria structure present in the artificial pollens of apple, kiwifruit, peach and pear, and contamination of high-risk pathogens was investigated. Acidovorax spp., Pantoea spp., Erwinia spp., Pseudomonas spp., and Xanthomonas spp., which are classified as potential high-risk pathogens, have been identified in imported pollens. This study presented the pollen-associated bacterial community structure, and the results are expected to be foundation for strengthening biosecurity in orchard industry.
