Establishment of the 2nd National Reference Standard for Diphtheria toxin in Korea

The reference standards perform an important role in standardization and consistent quality control of biologicals such as vaccines. The study was aimed to establish the 2nd national standard for diphtheria toxin used in diphtheria potency assay of diphtheria toxoid combined vaccines. The stocks of the first national standard established in 2007 were exhausted, and in 2019, Freeze-dried diphtheria toxin was produced in two lots, 1,962 and 1,942 vials respectively. The feasibility of manufacturing was evaluated through quality evaluation and long-term and accelerated stability tests for candidates. In order to assign the potency of candidate standards, the collaborative study was conducted with five institutions including vaccine manufacturers. The potency of the candidate standards was assigned a value of 210 L+/vial (95% confidence interval- MFDS- B-19-002: 208.52~221.58 L+/vial, MFDS-B-19-003: 208.63~219.61 L+/vial). It was confirmed that there was a significant difference in the basic statistics of institutions through One-way ANOVA. But when the post hoc test was conducted to verify the result of ANOVA, not much difference was shown from individual institutions as low variability. Additionally, statistical equivalence was confirmed from institutions. The candidate standard whose quality has been verified will be registered as the second national standard for diphtheria toxin.

Oak Tree Canker Disease Supports Arthropod Diversity in a Natural Ecosystem

The Plant Pathology Journal (2014)

Yong‐Bok Lee Su Jung An Chung Gyoo Park Jinwoo Kim Sangjo Han

Microorganisms have many roles in nature. They may act as decomposers that obtain nutrients from dead materials, while some are pathogens that cause diseases in animals, insects, and plants. Some are symbionts that enhance plant growth, such as arbuscular mycorrhizae and nitrogen fixation bacteria. However, roles of plant pathogens and diseases in natural ecosystems are still poorly understood. Thus, the current study addressed this deficiency by investigating possible roles of plant diseases in natural ecosystems, particularly, their positive effects on arthropod diversity. In this study, the model system was the oak tree (Quercus spp.) and the canker disease caused by Annulohypoxylon truncatum, and its effects on arthropod diversity. The oak tree site contained 44 oak trees; 31 had canker disease symptoms while 13 were disease-free. A total of 370 individual arthropods were detected at the site during the survey period. The arthropods belonged to 25 species, 17 families, and seven orders. Interestingly, the cankered trees had significantly higher biodiversity and richness compared with the canker-free trees. This study clearly demonstrated that arthropod diversity was supported by the oak tree canker disease.
