Muito além de uma história das leishmanioses no Novo Mundo / Far more than a history of leishmaniasis in the New World

Nesta obra, os autores não se limitaram à análise do objeto central da obra, isto é, a história das leishmanioses, mas também lançaram luz sobre pesquisas desenvolvidas acerca de várias enfermidades como malária, filariose, tripanossomíases, arboviroses, entre outras. No novo volume, é dada atenção especial ao papel desempenhado pela London School of Hygiene and Tropical Medicine e pelo parasitologista britânico Percy Cyril Claude Garnham na construção de uma nova rede centrada em nova abordagem, menos antropocêntrica e com maior interesse pelas zoonoses. A obra examina em detalhes a relação entre urbanização, surtos e expansão geográfica das leishmanioses tegumentares e a criação da Zona Franca de Manaus, a exploração de minério em Carajás e Pitinga, o projeto de produção de celulose em Jari e a construção das rodovias Transamazônica e Belém-Brasília, da hidrelétrica de Balbina e do gasoduto Coari-Manaus.O livro, portanto, apresenta uma perspectiva dinâmica sobre a pesquisa científica na região amazônica e as complexas interações entre saúde pública, desenvolvimento econômico e transformações socioambientais

Trópicos, ciência e leishmanioses: uma análise sobre circulação de saberes e assimetrias / The tropics, science, and leishmaniasis: an analysis of the circulation of knowledge and asymmetries

Resumo: O artigo investiga o processo de circulação de saberes ocorrido, nas primeiras décadas do século XX, entre os pesquisadores sul-americanos Edmundo Escomel (Peru) e Alfredo Da Matta (Brasil) e os europeus Alphonse Laveran (França) e Patrick Manson (Inglaterra) no que diz respeito à definição e validação da espundia como uma enfermidade particularizada da América do Sul, ao mesmo tempo que se postulava a necessidade do seu enquadramento no recém-criado grupo de moléstias denominado "leishmanioses". Compartilhando a recente preocupação em pensar a pesquisa histórica para além dos limites impostos pelo Estado nacional como categoria organizadora da narrativa, dialoga com alguns apologistas da história global/transnacional situando o caso específico nessa perspectiva analítica.

Abstract: The article investigates the process of circulation of knowledge which occurred during the first decades of the twentieth century between the South American researchers Edmundo Escomel (Peru) and Alfredo Da Matta (Brazil) and the Europeans Alphonse Laveran (France) and Patrick Manson (England) with regard to the definition and validation of espundia as a disease specific to South America, while simultaneously the need to insert this illness into the newly created group of diseases called the "leishmaniasis" was proposed. Sharing recent concerns in considering historical research beyond the limits imposed by the Nation-state as a category that organizes narratives, it dialogs with some apologists of global and transnational history, situating this specific case within this analytical perspective.

The history of leishmaniasis.

In this review article the history of leishmaniasis is discussed regarding the origin of the genus Leishmania in the Mesozoic era and its subsequent geographical distribution, initial evidence of the disease in ancient times, first accounts of the infection in the Middle Ages, and the discovery of Leishmania parasites as causative agents of leishmaniasis in modern times. With respect to the origin and dispersal of Leishmania parasites, the three currently debated hypotheses (Palaearctic, Neotropical and supercontinental origin, respectively) are presented. Ancient documents and paleoparasitological data indicate that leishmaniasis was already widespread in antiquity. Identification of Leishmania parasites as etiological agents and sand flies as the transmission vectors of leishmaniasis started at the beginning of the 20th century and the discovery of new Leishmania and sand fly species continued well into the 21st century. Lately, the Syrian civil war and refugee crises have shown that leishmaniasis epidemics can happen any time in conflict areas and neighbouring regions where the disease was previously endemic.

William Boog Leishman: parasitologist and politician.

Famous for the discovery of the parasite, Leishmania, named after him, and the invention of Leishman's stain, William Boog Leishman should perhaps be better known for his work in military and public health, particularly the prevention of typhoid. Leishman was a Medical Officer in the British Army from 1887 until his death in 1926. His early research was on diseases affecting troops posted to stations within the British Empire. He saw cases of Leishmaniasis while stationed in India, and was able to identify the causative organism from his detailed records of his observations. Leishman's most important contribution to public health, however, was his work with typhoid, a major cause of morbidity and mortality in the army. Leishman planned experiments and the collection of data to demonstrate the efficacy of anti-typhoid inoculation and, using his considerable political skills, advocated the adoption of the vaccine. He planned for the inoculation of troops in an emergency so, when war broke out in 1914, the vaccine was available to save thousands of lives. Leishman's colleagues and mentors included Ronald Ross and Almroth Wright. Leishman was less outspoken than either Ross or Wright; this paper shows how the different contributions of the three men overlapped.

William Boog Leishman-A Brief Reminder of His Life and Work on the Occasion of His 150th Birthday.

William Boog Leishman was born 150 years ago. Although his description of "small round or oval bodies" in a smear from the spleen pulp of a soldier who had died of kala-azar was not the first one of Leishmania and although Leishman did not make the diagnosis of kala-azar and misinterpreted the microorganisms to be trypanosomes, his article became the springboard for a series of studies that, within a few months, established Leishmania as a previously unknown genus of protozoa and led to appreciation of the clinical spectrum of kala-azar and the relationship between cutaneous and visceral leishmaniasis.

A Historical Overview of the Classification, Evolution, and Dispersion of Leishmania Parasites and Sandflies.

BACKGROUND: The aim of this study is to describe the major evolutionary historical events among Leishmania, sandflies, and the associated animal reservoirs in detail, in accordance with the geographical evolution of the Earth, which has not been previously discussed on a large scale. METHODOLOGY AND PRINCIPAL FINDINGS: Leishmania and sandfly classification has always been a controversial matter, and the increasing number of species currently described further complicates this issue. Despite several hypotheses on the origin, evolution, and distribution of Leishmania and sandflies in the Old and New World, no consistent agreement exists regarding dissemination of the actors that play roles in leishmaniasis. For this purpose, we present here three centuries of research on sandflies and Leishmania descriptions, as well as a complete description of Leishmania and sandfly fossils and the emergence date of each Leishmania and sandfly group during different geographical periods, from 550 million years ago until now. We discuss critically the different approaches that were used for Leishmana and sandfly classification and their synonymies, proposing an updated classification for each species of Leishmania and sandfly. We update information on the current distribution and dispersion of different species of Leishmania (53), sandflies (more than 800 at genus or subgenus level), and animal reservoirs in each of the following geographical ecozones: Palearctic, Nearctic, Neotropic, Afrotropical, Oriental, Malagasy, and Australian. We propose an updated list of the potential and proven sandfly vectors for each Leishmania species in the Old and New World. Finally, we address a classical question about digenetic Leishmania evolution: which was the first host, a vertebrate or an invertebrate? CONCLUSIONS AND SIGNIFICANCE: We propose an updated view of events that have played important roles in the geographical dispersion of sandflies, in relation to both the Leishmania species they transmit and the animal reservoirs of the parasites.

A History of Leishmaniasis in Iran from 19th Century Onward.

The history of leishmaniasis dates back to the distant past; however, its etiologic agent was unidentified until the mid-19th century. Here is an overview of some historical aspects of leishmaniasis in Iran mainly focused on the cutaneous form, from the mid-19th century onwards. In addition, short biographies of several contemporary researchers and experts of leishmaniasis and their achievements in the past decades are presented.

Leishmania tarentolae molecular signatures in a 300 hundred-years-old human Brazilian mummy.

BACKGROUND: L. tarentolae, the lizard-infecting species of Old World geckos, has been classified as non-pathogenic to man. While it has been demonstrated that L. tarentolae is capable of infecting human phagocytic cells and to differentiate into amastigote-like forms, there is no clear evidence for its efficient replication within macrophages. Here we provide first evidence for L. tarentolae ancient DNA sequences from bone marrow and intestines of a 300yo adult male. METHODS: We identified molecular signatures of Leishmania tarentolae, the lizard-infecting species of Old World geckos, in hard and soft tissue biopsies from a Brazilian mummy (A74) uncovered in Itacambira (Brazil) and dating to the Colonial Period (end of 18th/beginning of the 19th century). RESULTS: Our results imply that efficient replication of the parasite occurred within human macrophage and to lead to a systemic spread and visceralization in this individual. The ancient sequences show a 100% similarity with those of isolated L. tarentolae parasites grown on artificial nutrient media and a 99% similarity with two modern sequences isolated from reptiles. CONCLUSIONS: De facto, our findings re-open the debate about the potential survival of ancient L. tarentolae strain within human macrophage and its ability to spread systemically. They also raise ecological issues since it is unknown whether this parasite circulates in the reptilian reservoir in modern day Brazil or not. Investigations on fossil fauna and arthropods are needed to shed light on the interactions between saurian Leishmania and lizards in Brazil's remote and recent past.
