사과, 호박, 고추에서 분리된 탄저병균들(Colletotrichum gloeosporioides, C. orbiculare, C. acutatum)이 복분자딸기에 병원성을 나타냈으며. 특히 사과에서 분리된 탄저병균은 무상처 접종에서도 병원성을 나타냈다. 복분자 딸기에서 분리한 탄저병균(Colletotrichum gloeosporioides, C. coccodes, C. acutatum)은 사과와 딸기에서는 dropping 접종에 의해 병원성을 보였으나 고추와 토마토에서는 낮은 병원성을 나타내었다.

Infectious bronchitis virus (IBV) causes an acute and highly contagious viral disease of chicken that is great economic losses to the poultry industry worldwide. Among the IBV structural proteins, the high rate spike glycoprotein S1 gene mutation and antigenic variant strains have been reported in many countries. During the years 2012~2014, 10 IBV strains were isolated from infected chicken farms distributed in provinces of Jeonbuk. Analysis of the S1 gene sequences amplified from 10 isolated strains with QX strains showed nucleotide homologies ranging from 96.5 to 95.4%. Phylogenetic analysis revealed that all strains were clustered into QX-like groups. This study suggests that QX-like IBVs are circulating in commercial chicken farms in Jeonbuk. Therefore, the continuing survellance is significantly important for prevention and control of BIV infection.

Fowl adenovirus (FAdV) and chicken anemia virus (CAV) have gained much importance as an immunosuppressive and economically important emerging pathogen of poultry. This study was carried out to investigate the prevalence of FAdV and CAV infection in chickens. The groups were divided into Korean native chickens, broiler, layer hens and broiler breeder and set up groups according to age. As results, 12.5% of the native chicken, 2.5% of broiler and 6.7% of layer chicken were positive, respectively by PCR for FAdV. Serological test showed that 84.8%, 79.0%, 97.7% and 96.1% of chickens were positive for antibody to FAdV in native chickens, broiler, layer hens and broiler breeder. The prevalence of CAV infection were 20.0%, 7.5%, 16.7% and 10.0%, based on CAV gene detection by PCR. In serological test of CAV, 40.6%, 35.9%, 84.8% and 73.9% of chickens were positive in that groups.

Reproductive losses in a herd can be huge. Fetal reabsorption or undefined infertility often remain undetected. Routine herds monitoring for exposure, controlling the introduction of potential agent carriers, appropriate biosafety procedures, and vaccination where possible are together the best security against abortion and stillbirth inducing disease. For biosecurity of local farms, we performed antibody titers of abortion and stillbirth related diseases such as bovine viral diarrhea virus (BVDV), infectious bovine rhinotracheitis virus (IBRV), Neospora caninum, Toxoplasma gondii and Campylobacter fetus subsp venerealis. The blood samples were collected from 500 female Hanwoo over 1 year old of 100 farms in Jeonbuk eastern area. Champhylobater serological test was evaluated by the standard tube agglutination test (STAT) and other pathogen's antibodies were detected by indirect-enzyme linked immunoassay (I-ELISA). The seroprevalence of abortion and stillbirth inducing disease were BVDV 72.4%, IBRV 13.0%, N. caninum 1.2%, T. gondii 10.4% and C. venerealis 0.6%, irrespectively.

The purpose of this study was done to evaluate degradation characteristics of non-biodegradable organic matters including aromatic compounds in livestock wastewater using CFZ process. The CFZ process is consisted of coagulation/sedimentation, Fenton oxidation and zeolite adsoption process. degradation charateristics of each treatment water including livestock wastewater were analyzed by UV scanning, FT-IR and GC/MS. After coagulation/sedimentation process as 1st treatment, non-biodegradable matters remained after 1st treatment were removed by using OH radical produced in Fenton oxidation process. As a result of treatment using these processes, NBDCOD removal efficiency was over 90%. Increase of $E_2/E_3$ ratio (absorbance at 250 and 365 nm) in each treatment water means that aromaticity of livestock wastewater decreased. In case of GC/MS, most aromatics or polynuclear aromatics like benzene, phenol and scatol in livestock wastewater almost wasn't detected after oxidation using OH radical.

Porcine epidemic diarrhea (PED) is a highly contagious enteric viral disease of pigs with watery diarrhea in piglets, which ultimately results in huge economic losses in the swine industry. The spike (S) protein plays an important role in viral pathogenicity, tissue tropism, infection, dissemination and the trypsin-dependent proliferation of the PED virus (PEDV). In the present study, we determined the full-length spike (S) gene sequences of twenty PEDV field strains detected in Jeonbuk province in 2022. Phylogenetic analysis showed that the twenty PEDV field strains were classified into G2b group and shared 98.6~100% of nucleotide homology and 97.4~100% of amino acid homology with each other. Mutations of amino acid sequences on the neutralizing epitope of S protein were observed in the twenty field strains compared to the previous vaccine strain SM-98-1 (G1a group). Therefore, these amino acid mutations in the PEDV S protein may result in a new genotype of the virus and highly pathogenic virus, so continuous monitoring is required.

고추냉이 밭재배에서 강판에 갈아 생식할 수 있는 근경을 생산하는 작부체계를 개발하기 위해 중산간부 지역인 전북 진안군에서 12개월과 7개월간 묘를 육묘하였다. 육묘된 묘는 평야부인 전북 익산지역에 9월 하순에 이식되어 이듬해 5월에 근경수량을 조사하였다. 중산간부에서 7개월간 육묘한 묘에서 근경장 5cm 이상, 근경중 40 g 이상의 상품성 있는 근경이 13.0%의 비율로 생산되었고 72.9 kg/10a의 수량성을 보였으며 근경의 allylNCS 함량도 0.7771 mg/g으로 18개월간 물재배된 근경과 대등한 함량을 보였다.

2011년에 전북 정읍지역에 재배하는 쓴오이에서 탄저병이 발생하였다. 탄저병은 처음에 흑갈색의 작은 원형반점들이 잎과 열매에 나타났다. 감염된 잎과 열매는 작은 갈색-흑갈색 반점을 형성하고 병반이 커지거나 융합되어 큰 원형의 흑갈색 병반을 형성하였다. 탄저병 병징에서 분리한 병원균은 배양형태적 특성조사와 ITS rDNA 염기서열 분석결과 Colletotrichum gloeosporioides로 동정되었다. 분리된 C. gloeosporioides는 인공접종에 의한 병원성 검정에서도 동일한 병징을 나타내어 국내 처음으로 C. gloeosporioides에 의한 쓴오이 탄저병을 보고한다.
