ABSTRACT
Antimicrobial resistance (AMR) threatens health security and the economy worldwide. AMR bacteria can spread across humans, animals, food webs and the environment. Excessive use of antimicrobials in food-producing animals has been recognised as one of the main drivers of the emergence of resistant bacteria. This study aims to quantify and identify patterns of antimicrobial consumption in food-producing animals in Thailand in a three-year period (2017-2019). Milligrams of active ingredient from total volume of imported and locally manufactured products minus exports were obtained from Thai FDA. Annual population production of food-producing animals in 2017, 2018 and 2019 was compiled and validated through cooperation between the Department of Livestock Development (DLD), Department of Fisheries (DOF). The total amount of antimicrobial consumption for food-producing animals decreased 49.0% over the three-year period from 658.7 mg/PCUThailand in 2017 to 336.3 mg/PCUThailand in 2019. In 2017, the most common antimicrobials used was macrolides which was replaced by aminopenicillins and pleuromutilins in 2019, while tetracyclines was consistently common over the three-year period. Consumption of the WHO Critically Important Antimicrobials (CIA) group declined significantly over this period, from 259.0 in 2017 to 193.2 mg/PCUThailand in 2019 (a 25.4% reduction). Findings from this study were in line with national policies which curtails prudent use of antimicrobials in food-producing animals. The government should maintain the decreasing trend of consumption, in particular of the CIA category. Improving information systems which captures consumption by specific species contributes to precision of interventions to minimise prudent use in each species.

Antimicrobial resistance is a serious threat that affects all countries. The Global Action Plan on antimicrobial resistance and the United Nations Political Declaration on antimicrobial resistance set standards for countries to resolve antimicrobial resistance challenges under the One Health approach. We assess progress and challenges in implementing Thailand's national strategic plan on antimicrobial resistance 2017-2022, discuss interim outcomes and share lessons learnt. Major progress includes: establishing a national governance mechanism that leads high-impact policy on antimicrobial resistance and consolidates actions and multisectoral collaboration; creating a monitoring system and platform to track implementation of the strategic plan; and converting strategies of the strategic plan into actions such as controlling the distribution and use of antimicrobials in humans and animals. Interim results indicate that antimicrobial consumption in animals has nearly halved (exceeding the national goal of a 30% reduction) whereas other goals have not yet reached their targets. We have learnt that elevating antimicrobial resistance to high-level visibility and establishing a national governance mechanism is an important first step, and a monitoring and evaluation system should be developed in parallel with implementation. Securing funds is crucial. Policy coherence is needed to avoid duplication of actions. Highly ambitious goals, although yet to be achieved, can advance actions beyond expectations. Political commitment and collaboration across different sectors will continue to play important roles but might not be sustained without a well-designed governance structure to support long-term actions to address antimicrobial resistance.
La résistance aux antimicrobiens fait peser une sérieuse menace sur la planète tout entière. Le Plan d'action mondial pour combattre la résistance aux antimicrobiens ainsi que la Déclaration politique des Nations Unies sur la résistance aux agents antimicrobiens ont défini des normes pour les pays, afin qu'ils puissent faire face aux enjeux liés à la résistance aux antimicrobiens selon l'approche «One Health¼. Nous avons évalué les progrès et défis de la mise en Åuvre du plan stratégique national de la Thaïlande en la matière pour 20172022, mais aussi discuté des résultats provisoires et partagé les enseignements tirés. Parmi les principaux progrès accomplis figurent l'établissement d'un mécanisme de gouvernance national pour mener une politique à impact élevé sur la résistance aux antimicrobiens, renforcer les actions et favoriser la collaboration intersectorielle; la création d'un système de surveillance et d'une plateforme pour suivre la mise en Åuvre du plan stratégique; et enfin, la conversion des stratégies du plan en actions telles que le contrôle de la distribution et de l'usage des antimicrobiens chez les humains et les animaux. Les résultats provisoires indiquent que la consommation d'antimicrobiens chez les animaux a diminué de moitié (ce qui est supérieur à l'objectif national d'une réduction de 30%), tandis que les autres objectifs n'ont pas encore été atteints. Nous avons constaté qu'accroître la visibilité de la résistance aux antimicrobiens et instaurer un mécanisme de gouvernance national constituaient des étapes cruciales, et qu'un système de surveillance et d'évaluation devait être développé parallèlement à la mise en Åuvre. L'obtention de financements est elle aussi essentielle. Une politique cohérente est nécessaire pour éviter de multiplier les actions similaires. Fixer des objectifs très ambitieux, même s'ils ne sont pas encore atteints, permet en outre de faire progresser les actions au-delà des attentes. Enfin, l'engagement politique et la collaboration entre différents secteurs continueront à jouer un rôle prépondérant, mais ne pourront peut-être pas se poursuivre sans une structure de gouvernance bien conçue, capable de soutenir des actions à long terme visant à remédier à la résistance aux antimicrobiens.
La resistencia a los antimicrobianos es una grave amenaza que afecta a todos los países. El Plan de Acción Mundial sobre la resistencia a los antimicrobianos y la Declaración Política de las Naciones Unidas sobre la resistencia a los antimicrobianos establecen normas para que los países resuelvan los problemas de resistencia a los antimicrobianos en el marco del enfoque «Una única salud¼. Evaluamos los avances y los desafíos en la aplicación del plan estratégico nacional de Tailandia sobre la resistencia a los antimicrobianos 2017-2022, analizamos los resultados provisionales y compartimos las lecciones aprendidas. Entre los principales avances se encuentran: el establecimiento de un mecanismo de gobernanza nacional que lidera la política de alto impacto sobre la resistencia a los antimicrobianos y consolida las acciones y la colaboración multisectorial; la creación de un sistema de seguimiento y una plataforma para seguir la aplicación del plan estratégico; y la conversión de las estrategias del plan estratégico en acciones como el control de la distribución y el uso de antimicrobianos en humanos y animales. Los resultados provisionales indican que el consumo de antimicrobianos en animales se ha reducido casi a la mitad (superando el objetivo nacional de una reducción del 30 %), mientras que otros objetivos aún no han alcanzado sus metas. Hemos aprendido que elevar la resistencia a los antimicrobianos a una visibilidad de alto nivel y establecer un mecanismo de gobernanza nacional es un primer paso importante, y que debe desarrollarse un sistema de seguimiento y evaluación en paralelo a la implementación. Asegurar los fondos es crucial. La coherencia política es necesaria para evitar la duplicación de acciones. Unos objetivos muy ambiciosos, aunque todavía no se hayan alcanzado, pueden hacer avanzar las acciones más allá de las expectativas. El compromiso político y la colaboración entre los distintos sectores seguirán desempeñando un papel importante, pero podrían no mantenerse sin una estructura de gobernanza bien diseñada que apoye las acciones a largo plazo para hacer frente a la resistencia a los antimicrobianos.

The oxyuroid nematode Ichthyouris bursata Moravec & Prouza, 1995 (Pharyngodonidae) was recorded from the intestine of discus (Symphysodon spp. and hybrids) cultured in discus farms in Bangkok and Nonthaburi, central Thailand, during 2006 and 2007. This material made it possible to study in detail the morphology of this little known parasite species, using both light and scanning electron microscopy (the latter not previously used for the male). The SEM examination showed taxonomically important morphological features not previously reported or erroneously described, including the presence of three bilobed lips, a pair of sclerotised plate-like structures and a median cone-shaped outgrowth on the posterior cloacal lip, short 'hairs' on the cloacal lips, digital phasmids in the male and, sometimes, up to two filaments on the egg poles. This species is of South American origin, which was confirmed by its recent record from a free-living blue discus S. aequifasciatus Pellegrin in Brazil. The reproduction and transmission of I. bursata in the conditions of aquarium tanks is probably permitted by the direct (homoxenous) life-cycle of this parasite.

Physalopterid nematodes identified as Heliconema longissimum (Ortlepp, 1923) were collected from the stomach of rice-paddy eels Pisodonophis boro (Hamilton) (Anguilliformes: Ophichthidae) from two brackish-water localities (mangroves) in Thailand: one in Phan-Nga Province, southwestern Thailand, northeast of Phuket Island, and one in Ranong Province, near the border with Myanmar. Study of the morphology of this hitherto insufficiently known nematode species, including its first SEM examination, enabled a detailed redescription of H. longissimum. Present taxonomic problems in the subfamily Proleptinae Schulz, 1927 are discussed, where a new delimitation of Proleptus Dujardin, 1845, Heliconema Travassos, 1919 and Paraleptus Wu, 1927 is proposed based on the cephalic dentation. H. minnanensis [sic] Damin & Heqing, 2001 is transferred to Paraleptus Wu, 1927 as P. minnanensis (Damin & Heqing, 2001) n. comb. and Paraleptus chiloscyllii Yin & Zhang, 1983 transferred by Damin & Heqing (2001) to Heliconema, is retained in Paraleptus. H. ahiri Karve, 1941 is considered a junior synonym of H. longissimum (Ortlepp, 1923). The present finding of H. longissimum in Pisodonophis boro represents the first host record and the first record of this nematode from Thailand.
