An intricate history of human dispersal and geographic colonization has strongly affected the distribution of human pathogens. The pig tapeworm Taenia solium occurs throughout the world as the causative agent of cysticercosis, one of the most serious neglected tropical diseases. Discrete genetic lineages of T. solium in Asia and Africa/Latin America are geographically disjunct; only in Madagasc...

BACKGROUND Leptospirosis is a widespread but underreported cause of morbidity and mortality. It has rarely been reported in either humans or animals in Madagascar. METHODS We conducted a cross-sectional survey of the inhabitants in Moramanga, Madagascar, in June 2011, to estimate the prevalence of human infection using the microscopic agglutination test (MAT). This activity was carried out as...

The lemurs of Madagascar provide an excellent model for exploring evolutionary diversification. This study investigates genetic divergence among most extant lemur taxa in relation to potential geographical boundaries to gene flow. For this purpose, approximately 2,400 bp of mitochondrial DNA (part of the COIII gene; ND3, ND4L, and ND4 genes; and five tRNAs) were sequenced in a total of 131 lemu...

The aim of this research is to review the status and current trends about energy resources production potential new policies in Madagascar suggest possible solutions help government its sustainable policy development. results investigation showed that, nowadays Madagascar, more than 80% natural remaining not exploited. What more, order satisfy demand energy, country will need use up 12,000 MW h...

Philpott L. & W.L. Applequist (2023). Casearia razakamalalae (Salicaceae), une espèce nouvelle endémique du sud-est de Madagascar. Candollea 78: 27–32. En anglais, résumés anglais et français. Jacq. (Salicaceae) possède relativement peu d'espèces à Madagascar, mais sa taxonomie n'a pas encore été bien résolue. Une espèce, C. Appleq. est reconnue ici. se distingue par son indument papillaire sur...

Abstract Ruffed lemurs ( Varecia variegata and rubra ) are categorized as Critically Endangered on the IUCN Red List, genetic studies needed for assessing conservation value of captive populations. Using 280 mitochondrial DNA (mtDNA) D-loop sequences, we studied diversity structure ruffed in Madagascar, Europe North America. We found 10 new haplotypes: one from European V. population, three sub...

BACKGROUND Yersinia pestis is the causative agent of human plague and is endemic in various African, Asian and American countries. In Madagascar, the disease represents a significant public health problem with hundreds of human cases a year. Unfortunately, poor infrastructure makes outbreak investigations challenging. METHODOLOGY/PRINCIPAL FINDINGS DNA was extracted directly from 93 clinical ...

The biodiversity of Madagascar is extraordinarily distinctive, diverse, and endangered. It is therefore urgent that steps be taken to document, describe, interpret, and protect this exceptional biota. As a collaborative group of field and laboratory biologists, we employ a suite of methodological and analytical tools to investigate the vertebrate portion of Madagascar's fauna. Given that specie...

In Madagascan waters, both Tetraclita rufotincta Pilsbry 1916 and T. africana Ren 1989 have been reported. Tetraclita rufotincta is more widely distributed than T. africana, extending to the western Indian Ocean and east Africa. Tetraclita africana is reported from Madagascar and no further distribution record has been made apart from its type locality. Both species have pink parietes and are s...
