    Lee CF, Bezdĕk J
    Zootaxa, 2016 Oct 28;4179(1):1-41.
    PMID: 27811689 DOI: 10.11646/zootaxa.4179.1.1
    The genus Morphosphaera Baly, 1861 is revised. Eleven species are considered as valid, including, M. takizawai sp. nov. (Mt. Basor, 90 km N of Gua Musang, Malaysia, W. Kelantan), described from Malaysia and Indonesia. Color photos of habitus and drawings of diagnostic characters from eleven species are presented. The following synonymies are proposed: M. sodalis Chen, 1935 and M. brunnea Maulik, 1936 are junior synonyms of M. albipennis Allard, 1889; M. margaritacea Laboissière, 1930, M. viridipennis Laboissière, 1930, and M. prava Maulik, 1936 are junior synonyms of M. coomani Laboissière, 1930; M. gracilicornis Chen, 1963 is a junior synonym of M. maculicollis Baly, 1861; M. cavaleriei Laboissière, 1930, M. cincticollis Laboissière, 1930, M. marginata Laboissière, 1930, M. purpurea Laboissière, 1930, M. gingkoae Gressitt & Kimoto, 1963, and M. metallescens Gressitt & Kimoto, 1963 are junior synonyms of M. sumatrana Jacoby, 1886. The type material of M. impunctata Allard, 1890 from the Philippines was not found and its taxonomic status remains uncertain. Morphosphaera peregrina Weise, 1913 is transferred to the genus Borneola Mohamedsaid, 1998 nov. comb. A neotype is designated for Chrysomela japonica Hornstedt, 1788. Lectotypes are designated for the following species: Adorium chrysomeloides Bates, 1866, A. japonicum Baly, 1874, Morphosphaera albipennis Allard, 1889, M. bimaculata Chûjô, 1938, M. caerulea Jacoby, 1896, M. cavaleriei Laboissière, 1930, M. collaris Laboissière, 1930, M. formosa Laboissière, 1930, M. marginata Laboissière, 1930, M. montivaga Maulik, 1936, M. prava Maulik, 1936, M. purpurea Laboissière, 1930, M. sumatrana Jacoby, 1886, M. viridipennis Laboissière, 1930, and Galerucida simplex Weise, 1922.

  4. Fulltext The Malacca Strait separates distinct faunas of poorly-flying Cautires net-winged beetles
    Jiruskova A, Motyka M, Bocek M, Bocak L
    PeerJ, 2019;7:e6511.
    PMID: 30863675 DOI: 10.7717/peerj.6511
    We investigated the spatial and temporal patterns of Cautires diversification on the Malay Peninsula and Sumatra to understand if the narrow and frequently dry Malacca Strait separates different faunas. Moreover, we analyzed the origin of Cautires in Malayan and Sumatran mountains. We sampled 18 localities and present the mtDNA-based phylogeny of 76 species represented by 388 individuals. The phylogenetic tree was dated using mtDNA evolution rates and the ancestral ranges were estimated using the maximum likelihood approach. The phylogeny identified multiple lineages on the Malay Peninsula since the Upper Eocene (35 million years ago, mya) and a delayed evolution of diversity in Sumatra since the Upper Oligocene (26 mya). A limited number of colonization events across the Malacca Strait was identified up to the Pliocene and more intensive faunal exchange since the Pleistocene. The early colonization events were commonly followed by in situ diversification. As a result, the Malacca Strait now separates two faunas with a high species-level turnover. The montane fauna diversified in a limited space and seldom took part in colonization events across the Strait. Besides isolation by open sea or a savannah corridor, mimetic patterns could decrease the colonization capacity of Cautires. The Malay fauna is phylogenetically more diverse and has a higher value if conservation priorities should be defined.

  5. Use of sterols and linear alkylbenzenes as molecular markers of sewage pollution in Southeast Asia
    Thomes MW, Vaezzadeh V, Zakaria MP, Bong CW
    Environ Sci Pollut Res Int, 2019 Nov;26(31):31555-31580.
    PMID: 31440968 DOI: 10.1007/s11356-019-05936-y
    Southeast Asia has undergone rapid developments in terms of urbanization, economic and population growth. The progress in sewerage treatment infrastructure has not kept pace with such developments. The inadequacy and inefficiency of sewerage systems has prompted the release of untreated sewage into the aquatic environment of Southeast Asia causing many waterborne illnesses since surface water is utilized for recreational, agricultural and aquaculture purposes and, above all, as a source of water intake in Southeast Asia. This paper will review the current data on molecular markers of sewage pollution including sterols and linear alkylbenzenes (LABs) in Southeast Asian aquatic environment to clarify the state of sewage pollution and the competence of sewage treatment plants (STPs) in this area. Despite the importance of sewage pollution research in the region, the number of studies using molecular markers to trace the sources of sewage pollution is limited. So far, indicators of sewage pollution have been investigated in aquatic environments of Indonesia, Vietnam, Malaysia, the Philippines, Thailand, Cambodia and Brunei among Southeast Asian countries. The concentrations and diagnostic ratios of faecal sterols and LABs show the release of untreated and primary treated urban waste into water bodies of these countries. Further studies are required to fill the data gaps in Southeast Asia and come to a better understanding of the trends of sewage pollution in this part of the world. Graphical abstract.

  6. Fulltext Serological Evidence of Japanese Encephalitis Virus Circulation in Asian Children From Dengue-Endemic Countries
    Nealon J, Taurel AF, Yoksan S, Moureau A, Bonaparte M, Quang LC, et al.
    J Infect Dis, 2019 Jan 09;219(3):375-381.
    PMID: 30165664 DOI: 10.1093/infdis/jiy513
    Background: Japanese encephalitis virus (JEV) is a zoonotic, mosquito-borne flavivirus, distributed across Asia. Infections are mostly mild or asymptomatic, but symptoms include neurological disorders, sequelae, and fatalities. Data to inform control strategies are limited due to incomplete case reporting.

    Methods: We used JEV serological data from a multicountry Asian dengue vaccine study in children aged 2-14 years to describe JEV endemicity, measuring antibodies by plaque reduction neutralization test (PRNT50).

    Results: A total 1479 unvaccinated subjects were included. A minimal estimate of pediatric JEV seroprevalence in dengue-naive individuals was 8.1% in Indonesia, 5.8% in Malaysia, 10.8% in the Philippines, and 30.7% in Vietnam, translating to annual infection risks varying from 0.8% (in Malaysia) to 5.2% (in Vietnam). JEV seroprevalence and annual infection estimates were much higher in children with history of dengue infection, indicating cross-neutralization within the JEV PRNT50 assay.

    Conclusions: These data confirm JEV transmission across predominantly urban areas and support a greater emphasis on JEV case finding, diagnosis, and prevention.

  7. Watson, Swellengrebel and species sanitation: environmental and ecological aspects
    Bradley DJ
    Parassitologia, 1994 Aug;36(1-2):137-47.
    PMID: 7898951
    Following the discovery of mosquito transmission of malaria, the theory and practice of malaria control by general and selective removal of specific vector populations resulted particularly from Malcolm Watson's empirical work in peninsular Malaysia, first in the urban and peri-urban areas of Klang and Port Swettenham and subsequently in the rural rubber plantations, and from the work of N.H. Swellengrebel in nearby Indonesia on the taxonomy, ecology and control of anophelines. They developed the concept of species sanitation: the selective modification of the environment to render a particular anopheline of no importance as a vector in a particular situation. The lack of progress along these lines in India at that time is contrasted with that in south-east Asia. The extension of species sanitation and related concepts to other geographical areas and to other vector-borne disease situations is outlined.

  8. The rediscovery of Schaefer's Spine-jawed Snake (Xenophidion schaeferi Günther Manthey, 1995) (Serpentes, Xenophidiidae) from Peninsular Malaysia with notes on its variation and the first record of the genus from Sumatra, Indonesia
    Quah ESH, Grismer LL, Jetten T, Wood PLJ, Miralles A, Sah SAM, et al.
    Zootaxa, 2018 Jun 27;4441(2):366-378.
    PMID: 30314015 DOI: 10.11646/zootaxa.4441.2.10
    The family Xenophidiidae is an extremely rare and little-known family of snakes that contains only two species, Xenophidion acanthognathus Günther Manthey and X. schaeferi Günther Manthey that are each known only from their holotypes. We report on the rediscovery of X. schaeferi from two new locations in southern Peninsular Malaysia. The new specimens differ markedly from the holotype of X. schaeferi in colour pattern and are more akin to the patterning of X. acanthognathus from Borneo. However, molecular analyses of one of the new specimens reveal that it only differs from the holotype of X. schaeferi by a minimum sequence divergence of 0.27%. An expanded description of the species based on these specimens is provided and phenotypic variation within the species is discussed. We also report the first record of the genus Xenophidion from West Sumatra, Indonesia. These sensational discoveries continue to underscore the fact that southern Peninsular Malaysia and upland areas of Southeast Asia in general still harbour unrealized herpetological diversity and are still in need of field research-based taxonomic studies.

  9. Fulltext Evolutionary cascades induced by large frugivores
    Brodie JF
    Proc Natl Acad Sci U S A, 2017 11 07;114(45):11998-12002.
    PMID: 29078339 DOI: 10.1073/pnas.1710172114
    Large, fruit-eating vertebrates have been lost from many of the world's ecosystems. The ecological consequences of this defaunation can be severe, but the evolutionary consequences are nearly unknown because it remains unclear whether frugivores exert strong selection on fruit traits. I assessed the macroevolution of fruit traits in response to variation in the diversity and size of seed-dispersing vertebrates. Across the Indo-Malay Archipelago, many of the same plant lineages have been exposed to very different assemblages of seed-dispersing vertebrates. Phylogenetic analysis of >400 plant species in 41 genera and five families revealed that average fruit size tracks the taxonomic and functional diversity of frugivorous birds and mammals. Fruit size was 40.2-46.5% smaller in the Moluccas and Sulawesi (respectively), with relatively depauperate assemblages of mostly small-bodied animals, than in the Sunda Region (Borneo, Sumatra, and Peninsular Malaysia), with a highly diverse suite of large and small animals. Fruit color, however, was unrelated to vertebrate diversity or to the representation of birds versus mammals in the frugivore assemblage. Overhunting of large animals, nearly ubiquitous in tropical forests, could strongly alter selection pressures on plants, resulting in widespread, although trait-specific, morphologic changes.

  10. Deforestation and avian extinction on tropical landbridge islands
    Sodhi NS, Wilcove DS, Lee TM, Sekercioglu CH, Subaraj R, Bernard H, et al.
    Conserv Biol, 2010 Oct;24(5):1290-8.
    PMID: 20345403 DOI: 10.1111/j.1523-1739.2010.01495.x
    There are few empirical data, particularly collected simultaneously from multiple sites, on extinctions resulting from human-driven land-use change. Southeast Asia has the highest deforestation rate in the world, but the resulting losses of biological diversity remain poorly documented. Between November 2006 and March 2008, we conducted bird surveys on six landbridge islands in Malaysia and Indonesia. These islands were surveyed previously for birds in the early 1900 s, when they were extensively forested. Our bird inventories of the islands were nearly complete, as indicated by sampling saturation curves and nonparametric true richness estimators. From zero (Pulau Malawali and Pulau Mantanani) to 15 (Pulau Bintan) diurnal resident landbird species were apparently extirpated since the early 1900 s. Adding comparable but published extinction data from Singapore to our regression analyses, we found there were proportionally fewer forest bird extinctions in areas with greater remaining forest cover. Nevertheless, the statistical evidence to support this relationship was weak, owing to our unavoidably small sample size. Bird species that are restricted to the Indomalayan region, lay few eggs, are heavier, and occupy a narrower habitat breadth, were most vulnerable to extinction on Pulau Bintan. This was the only island where sufficient data existed to analyze the correlates of extinction. Forest preservation and restoration are needed on these islands to conserve the remaining forest avifauna. Our study of landbridge islands indicates that deforestation may increasingly threaten Southeast Asian biodiversity.

  11. Fulltext Niches, body sizes, and the disassembly of mammal communities on the Sunda Shelf islands
    Okie JG, Brown JH
    Proc Natl Acad Sci U S A, 2009 Nov 17;106 Suppl 2:19679-84.
    PMID: 19805179 DOI: 10.1073/pnas.0901654106
    The rising sea level at the end of the Pleistocene that created the islands of the Sunda Shelf in Indonesia and Malaysia provides a natural experiment in community disassembly and offers insights into the effects of body size and niches on abundance, distribution, and diversity. Since isolation, terrestrial mammal communities of these islands have been reduced by extinction, with virtually no offsetting colonization. We document three empirical patterns of disassembly, all of which are significantly different from null models of random assembly: (i) a diversity-area relationship: the number of taxa is strongly and positively correlated with island area; (ii) nested subset composition: species that occur on small islands tend to be subsets of more diverse communities inhabiting larger islands; and (iii) body size distributions: species of intermediate body sizes occur on the greatest number of islands, and smaller islands have smaller ranges of body sizes, caused by the absence of species of both very large and extremely small size. These patterns reveal the role of body size and other niche characteristics, such as habitat requirements and trophic status, in the differential susceptibility of taxa to extinction.

  12. Fulltext Genome of a middle Holocene hunter-gatherer from Wallacea
    Carlhoff S, Duli A, Nägele K, Nur M, Skov L, Sumantri I, et al.
    Nature, 2021 Aug;596(7873):543-547.
    PMID: 34433944 DOI: 10.1038/s41586-021-03823-6
    Much remains unknown about the population history of early modern humans in southeast Asia, where the archaeological record is sparse and the tropical climate is inimical to the preservation of ancient human DNA1. So far, only two low-coverage pre-Neolithic human genomes have been sequenced from this region. Both are from mainland Hòabìnhian hunter-gatherer sites: Pha Faen in Laos, dated to 7939-7751 calibrated years before present (yr cal BP; present taken as AD 1950), and Gua Cha in Malaysia (4.4-4.2 kyr cal BP)1. Here we report, to our knowledge, the first ancient human genome from Wallacea, the oceanic island zone between the Sunda Shelf (comprising mainland southeast Asia and the continental islands of western Indonesia) and Pleistocene Sahul (Australia-New Guinea). We extracted DNA from the petrous bone of a young female hunter-gatherer buried 7.3-7.2 kyr cal BP at the limestone cave of Leang Panninge2 in South Sulawesi, Indonesia. Genetic analyses show that this pre-Neolithic forager, who is associated with the 'Toalean' technocomplex3,4, shares most genetic drift and morphological similarities with present-day Papuan and Indigenous Australian groups, yet represents a previously unknown divergent human lineage that branched off around the time of the split between these populations approximately 37,000 years ago5. We also describe Denisovan and deep Asian-related ancestries in the Leang Panninge genome, and infer their large-scale displacement from the region today.

    Clinical epidemiology (CE) and evidence-based medicine (EBM) have become an important part of medical school curricula. This report describes the implementation and some preliminary outcomes of an integrated CE and EBM module in the Faculty of Medicine Universitas Indonesia (UI), Jakarta and in the University of Malaya (UM) in Kuala Lumpur. A CE and EBM module, originally developed at the University Medical Center Utrecht (UMCU), was adapted for implementation in Jakarta and Kuala Lumpur. Before the start of the module, UI and UM staff followed a training of teachers (TOT). Student competencies were assessed through pre and post multiple-choice knowledge tests, an oral and written structured evidence summary (evidence-based case report, EBCR) as well as a written exam. All students also filled in a module evaluation questionnaire. The TOT was well received by staff in Jakarta and Kuala Lumpur and after adaptation the CE and EBM modules were integrated in both medical schools. The pre-test results of UI and UM were significantly lower than those of UMCU students (p

  15. Strategies for access to affordable hepatitis C testing and treatment in Asia
    Khwairakpam G, Burry J
    Curr Opin HIV AIDS, 2019 01;14(1):1-6.
    PMID: 30480583 DOI: 10.1097/COH.0000000000000514
    PURPOSE OF REVIEW: With increasing availability of generic direct-acting antivirals (DAAs) and associated price reductions, various governments, multilateral institutions, and donors have started providing testing and treatment for hepatitis C virus (HCV) infection. More data on the quality of these generic medicines and on cost-effectiveness of their use are becoming widely available. This review seeks to describe some of the treatment programs for HCV that are evolving in Cambodia, India, Indonesia, Malaysia, Myanmar, and Thailand.

    RECENT FINDINGS: The quality of multiple generic DAAs has been shown to be bioequivalent to innovator formulations, with generic versions achieving high cure rates in real-world settings. Although published materials are limited, there is expanding experience with local pilot and national treatment programs which are largely being funded by national governments and other institutions.

    SUMMARY: Countries and other public health stakeholders are recognizing the need to scale up HCV diagnosis and treatment programs using generic DAAs. However, local pilot or national treatment programs need to be massively expanded to eliminate HCV in high-burden areas.

  18. Potential forensic implications of kerokan therapy - a traditional Indonesian therapy associated with neck bruising
    Samberkar PN, Samberkar SP, Byard RW
    Med Sci Law, 2020 Oct;60(4):315-318.
    PMID: 32501165 DOI: 10.1177/0025802420926867
    Kerokan is a traditional Indonesian treatment involving abrading the skin over various parts of the body with a blunt object such as a coin or a piece of ginger which may create suspicious injuries. Here, the case of a 30-year-old woman who had undergone kerokan therapy is reported. She was complaining of retro-sternal pain and epigastric discomfort and subsequently became markedly short of breath and died. The observation of injuries predominantly located around the neck initiated a police investigation and forensic autopsy. Scattered abrasions, blisters and bruises were present on the forehead, the bridge of the nose extending to the ala, the upper and anterior aspect of the chin and the sternal notch, with discrete fresh and scabbed abrasions around the neck, over the sternum and on the backs of both hands. There were, however, no facial or conjunctival petechiae and no bruising of the underlying strap muscles, or fractures of the hyoid bone or thyroid cartilage. Histology revealed that myocarditis was the cause of death. Traditional practices may cause unusual bruises, abrasions, blisters and burns that may raise suspicion of inflicted injury from an assault. Knowledge of the manifestations of socio-ethnic practices such as kerokan is important in the evaluation of trauma in specific cultural groups.

  20. About Ganoderma boninense in oil palm plantations of Sumatra and peninsular Malaysia: Ancient population expansion, extensive gene flow and large scale dispersion ability
    Mercière M, Boulord R, Carasco-Lacombe C, Klopp C, Lee YP, Tan JS, et al.
    Fungal Biol, 2017 Jun-Jul;121(6-7):529-540.
    PMID: 28606348 DOI: 10.1016/j.funbio.2017.01.001
    Wood rot fungi form one of the main classes of phytopathogenic fungus. The group includes many species, but has remained poorly studied. Many species belonging to the Ganoderma genus are well known for causing decay in a wide range of tree species around the world. Ganoderma boninense, causal agent of oil palm basal stem rot, is responsible for considerable yield losses in Southeast Asian oil palm plantations. In a large-scale sampling operation, 357 sporophores were collected from oil palm plantations spread over peninsular Malaysia and Sumatra and genotyped using 11 SSR markers. The genotyping of these samples made it possible to investigate the population structure and demographic history of G. boninense across the oldest known area of interaction between oil palm and G. boninense. Results show that G. boninense possesses a high degree of genetic diversity and no detectable genetic structure at the scale of Sumatra and peninsular Malaysia. The fact that few duplicate genotypes were found in several studies including this one supports the hypothesis of spore dispersal in the spread of G. boninense. Meanwhile, spatial autocorrelation analysis shows that G. boninense is able to disperse across both short and long distances. These results bring new insight into mechanisms by which G. boninense spreads in oil palm plantations. Finally, the use of approximate Bayesian computation (ABC) modelling indicates that G. boninense has undergone a demographic expansion in the past, probably before the oil palm was introduced into Southeast Asia.
