ABSTRACTWe detected and identified genotypes of human-pathogenic microsporidia in fecal samples from 51 asymptomatic captive-bred pet parrots in South Korea. Microsporidia were identified in 8 samples (15.7%); 7 parrots tested positive forEncephalitozoon hellem, and 1 parrot tested positive for bothE. hellemandEncephalitozoon cuniculi. In genotypic identifications,E. hellemwas present in genotypes 1A and 2B andE. cuniculiwas present in genotype II. Pet parrots might be a source of human microsporidian infection.

ABSTRACT Of four genotypes of Encephalitozoon cuniculi, E. cuniculi genotype II is considered to represent a parasite that occurs in many host species in a latent asymptomatic form, whereas E. cuniculi genotype III seems to be more aggressive, and infections caused by this strain can lead to the death of even immunocompetent hosts. Although albendazole has been considered suitable for treatment of Encephalitozoon species, its failure in control of E. cuniculi genotype III infection has been reported. This study determined the effect of a 100× recommended daily dose of albendazole on an Encephalitozoon cuniculi genotype III course of infection in immunocompetent and immunodeficient mice and compared the results with those from experiments performed with a lower dose of albendazole and E. cuniculi genotype II. The administration of the regular dose of abendazole during the acute phase of infection reduced the number of affected organs in all strains of mice and absolute counts of spores in screened organs. However, the effect on genotype III was minor. Surprisingly, no substantial effect was recorded after the use of a 100× dose of albendazole, with larger reductions seen only in the number of affected organs and absolute counts of spores in all strains of mice, implying variations in albendazole resistance between these Encephalitozoon cuniculi genotypes. These results imply that differences in the course of infection and the response to treatment depend not only on the immunological status of the host but also on the genotype causing the infection. Understanding how microsporidia survive in hosts despite targeted antimicrosporidial treatment could significantly contribute to research related to human health.

ABSTRACT Human-associated microsporidia were frequently observed in fecal samples of 331 feral pigeons in Amsterdam, The Netherlands, obtained during high- and low-breeding periods. Thirty-six of 331 samples (11%) contained the human pathogens Enterocytozoon bieneusi (n = 18), Encephalitozoon hellem (n = 11), Encephalitozoon cuniculi (n = 6), and Encephalitozoon intestinalis (n = 1); 5 samples contained other microsporidia. Pigeon feces can be an important source of human microsporidian infection.

In September 2019, African swine fever (ASF) was reported in South Korea for the first time. Since then, more than 651 ASF cases in wild boars and 14 farm outbreaks have been notified in the country. Despite the efforts to eradicate ASF among wild boar populations, the number of reported ASF-positive wild boar carcasses have increased recently. The purpose of this study was to characterize the spatial distribution of ASF-positive wild boar carcasses to identify the risk factors associated with the presence and number of ASF-positive wild boar carcasses in the affected areas. Because surveillance efforts have substantially increased in early 2020, we divided the study into two periods (2 October 2019 to 19 January 2020, and 19 January to 28 April 2020) based on the number of reported cases and aggregated the number of reported ASF-positive carcasses into a regular grid of hexagons of 3-km diameter. To account for imperfect detection of positive carcasses, we adjusted spatial zero-inflated Poisson regression models to the number of ASF-positive wild boar carcasses per hexagon. During the first study period, proximity to North Korea was identified as the major risk factor for the presence of African swine fever virus. In addition, there were more positive carcasses reported in affected hexagons with high habitat suitability for wild boars, low heat load index (HLI), and high human density. During the second study period, proximity to an ASF-positive carcass reported during the first period was the only significant risk factor for the presence of ASF-positive carcasses. Additionally, low HLI and elevation were associated with an increased number of ASF-positive carcasses reported in the affected hexagons. Although the proportion of ASF-affected hexagons increased from 0.06 (95% credible interval (CrI): 0.05–0.07) to 0.09 (95% CrI: 0.08–0.10), the probability of reporting at least one positive carcass in ASF-affected hexagons increased from 0.49 (95% CrI: 0.41–0.57) to 0.73 (95% CrI: 0.66–0.81) between the two study periods. These results can be used to further advance risk-based surveillance strategies in the Republic of Korea.

Purpose The purpose of this study is to explore the essential cause for the policy failure of Trade Adjustment Assistance (TAA) in South Korea. Design/methodology/approach To substantiate the claims made for the failure of the policy, this paper focuses on the differences in policy preferences among the government ministries and agencies involved in TAA. Findings The failure in the TAA policy, according to this study, was attributed to the conflicts and miscoordination arising from the differences in policy preferences among government ministries and agencies. To rectify this failure, the South Korean government had to revise its laws and regulations several times over a short period. Originality/value Drawing on the analytical framework of the literature on policy failure, this paper examines the causal relationships between outcomes of TAA policy and the conflicts or miscoordination among government bodies at each stage: initiatives and planning, implementation and operation of the policy.

Significance Tehran’s more sophisticated sanctions avoidance tactics and greater willingness to test Washington’s enforcement have substantially boosted exports from 2019 lows. The slow progress on a US-Iranian mutual return to compliance with the 2015 nuclear deal, the Joint Comprehensive Plan of Action (JCPOA), has increased market uncertainty. Impacts Before sanctions lifting, limited waivers might add a few hundred thousand b/d of exports to US allies such as India, Japan and South Korea. New foreign oil investment will depend on views of Tehran’s domestic politics after June polls and the durability of a deal with Washington. Post-sanctions, Iran’s efforts to regain market share will create tensions with OPEC+ partners in quota negotiations.

Purpose The purpose of this paper is to examine how corruption has changed over time in South Korea and to explore how the corruption control and prevention efforts of the Korean government have been successful and failed. Design/methodology/approach This paper draws on institutional theory to formulate a qualitative analysis to assess the effectiveness of anti-corruption policies and measures, and to identify the strengths and weaknesses of anti-corruption reform efforts in South Korea. Findings This paper argues that while the Korean government has been quite successful in building anti-corruption institutions to control low-level petty corruption, it has failed to institutionalize anti-corruption institutions to curb high-level grand corruption. Originality/value While many studies have attempted to identify the successful factors of fighting corruption, this paper draws a theoretical distinction between institution-building vs institutionalization to examine the success and failure of corruption control and prevention efforts in South Korea.

ABSTRACT The biocide triclosan is used in many personal care products, including toothpastes, soaps, clothing, and medical equipment. Consequently, it is present as a contaminant in the environment and has been detected in some human fluids, including serum, urine, and milk. Staphylococcus aureus is an opportunistic pathogen that colonizes the noses and throats of approximately 30% of the population. Colonization with S. aureus is known to be a risk factor for several types of infection. Here we demonstrate that triclosan is commonly found in the nasal secretions of healthy adults and the presence of triclosan trends positively with nasal colonization by S. aureus. We demonstrate that triclosan can promote the binding of S. aureus to host proteins such as collagen, fibronectin, and keratin, as well as inanimate surfaces such as plastic and glass. Lastly, triclosan-exposed rats are more susceptible to nasal colonization with S. aureus. These data reveal a novel factor that influences the ability of S. aureus to bind surfaces and alters S. aureus nasal colonization. IMPORTANCE Triclosan has been used as a biocide for over 40 years, but the broader effects that it has on the human microbiome have not been investigated. We demonstrate that triclosan is present in nasal secretions of a large portion of a test population and its presence correlates with Staphylococcus aureus nasal colonization. Triclosan also promotes the binding of S. aureus to human proteins and increases the susceptibility of rats to nasal colonization by S. aureus. These findings are significant because S. aureus colonization is a known risk factor for the development of several types of infections. Our data demonstrate the unintended consequences of unregulated triclosan use and contribute to the growing body of research demonstrating inadvertent effects of triclosan on the environment and human health.
