Sustainable antimicrobial resistance surveillance: time for a global funding mechanism
Posted 07/01/2025. The continued costs of a standard national AMR surveillance system are predicted to account for over 5% of the total domestic general government health expenditure (GGHE-D) for 28 LMICs and more than 2% of GGHE-D for 46 LMICs. This high cost is not sustainable without a long-term global financing mechanism. By Liz Ashley
AmpC β-lactamases detected in Southeast Asian Escherichia coli and Klebsiella pneumoniae
Posted 20/12/2024. AmpC β-lactamases are a neglected cause of third generation cephalosporin resistance in Southeast Asia. This collaboration between COMRU, LOMWRU and SMRU showed that AmpC β-lactamases are an important cause of infection, though infections may be going undetected due to a lack of testing resulting in sub-optimal treatment for patients.

Ethical and cultural implications for conducting verbal autopsies in South and Southeast Asia: a qualitative study
Posted 20/12/2023. The verbal autopsy method can be sensitive to the individuals interviewed, their families and communities. Prior to study implementation, Nan Shwe Nwe Htun, Tom Peto and SEACTN colleagues sought to explore local beliefs and practices about death to inform appropriate bioethical practices and found that verbal autopsy is acceptable across a wide range of cultural settings in Bangladesh, Myanmar, Thailand, Laos PDR, and Cambodia.
Accuracy of the direct agglutination test for diagnosis of visceral leishmaniasis: a systematic review and meta-analysis
Posted 01/12/2023. Parasitology is the gold standard for the diagnosis of visceral leishmaniasis (VL), however, other less invasive tests are available such as the direct agglutination test (DAT). As part of the series of systematic reviews and meta-analysis on diagnostic accuracy of diagnostics for FIEBRE infections, Tamalee Roberts and colleagues estimate the diagnostic sensitivity and specificity of DAT for the diagnosis of VL.
A systematic review of neglected tropical diseases (NTDs) in Myanmar
Posted 21/11/2023. Neglected tropical diseases (NTDs) are a group of preventable and treatable diseases common in Myanmar, primarily affecting marginalized rural communities. Myo Swe and colleagues provide an overview of reported NTDs in Myanmar over 100 years, indicating gaps in knowledge about certain diseases to inform future research directions related to NTDs in Myanmar.

Longitudinal comparison of bacterial pathogen seropositivity among wet market vendors in the Lao People's Democratic Republic
Posted 31/08/2023. Vendors at wet markets in Laos may be exposed to different zoonotic pathogens depending on the types of food they sell. A one-year serological survey by Matthew Robinson and colleagues identified that individuals selling vegetables, domestic farmed meat, or wildlife meat, were potentially infected by important bacterial pathogens associated with both farmed animals and wildlife.
Malaria outbreak in Laos driven by a selective sweep for Plasmodium falciparum kelch13 R539T mutants: a genetic epidemiology analysis
Posted 14/12/2022. Malaria outbreaks can be driven by genetic selection rather than environmental or behavioural causes. Varanya Wasakul, Olivo Miotto and colleagues investigated a Plasmodium falciparum outbreak in Attapeu, Laos, in 2020-2021, using genomic epidemiology methods to elucidate parasite population dynamics, identify the outbreak’s causes and reconstruct the origin of the circulating strains.
Orientia tsutsugamushi in Chiggers and Small Mammals in Laos
Posted 06/12/2011. Scrub typhus is an important cause of febrile illness in Laos. Ivo Elliott and colleagues collected, identified and tested small mammals hosts and vector chigger mites for Orientia tsutsugamushi, the causative pathogen. A single pool of chiggers tested PCR positive and 16/52 (31%) of small mammals were seropositive.
