'Laishram Chandreshwor Singh' 'Narender Singh Negi' 'V. Ramesh' 'Poonam Salotra' 'Mauricio Martins Rodrigues'] A rapid and accurate method to detect and quantify Leishmania parasite is urgently needed to facilitate early diagnosis of Leishmaniasis and monitoring of antileishmania therapy. In this study, real-time assay…

'Natalia Paula Macchiaverna' 'Julián Antonio Alvarado Otegui' 'Hernán Darío Argibay' 'María del Pilar Fernández' 'Ricardo Esteban Gürtler' 'Marta Victoria Cardinal'] Background The distribution of parasite load across hosts may modify the transmission dynamics of infectious diseases. Chagas disease is caused by a…

'Helena Havelková' 'Milena Svobodová' 'Peter Demant' 'Marie Lipoldová'] Leishmaniasis is a serious health problem in many countries, and continues expanding to new geographic areas including Europe and USA. This disease, caused by parasites of Leishmania spp. and transmitted by phlebotomine sand flies, causes up to 1.3…

Heleidomermis magnapapula parasitizes the blood-feeding midge Culicoides sonorensis. Most (84%) single mermithid infective second stage juveniles (J2) developed into adult females, while parasitism by multiple J2 yielded 97% male adults. Nematodes emerged from the midge larval host as adults and mated immediately…

'Samuel S. Bowser' 'Geerat J. Vermeij'] We studied the population dynamics and parasite load of the foraminifer Cibicides antarcticus on its host the Antarctic scallop Adamussium colbecki from three localities differing by sea ice cover within western McMurdo Sound, Ross Sea, Antarctica: Explorers Cove, Bay of Sails…

It seems obvious that the number of pathogens should be important in the pathogenesis of an infectious disease [1], [2]. The relationship between the pathogen load and severity is one of the most fundamental questions, and yet, strangely, one of the most difficult to answer [3]. One reason for this is that it is often…

'Eduardo Antônio Donadi' 'João Santana da Silva' 'José Antônio Marin-Neto'] Background: Chronic Chagas disease (CChD), one of the infectious parasitic diseases with the greatest social and economic impact upon a large part of the American continent, has distinct clinical manifestations in humans (cardiac, digestive, or…

'Adam Butler' 'Motohiro Ito' 'Katsufumi Sato' 'Jonathan A. Green'] Parasites have profound fitness effects on their hosts, yet these are often sub-lethal, making them difficult to understand and quantify. A principal sub-lethal mechanism that reduces fitness is parasite-induced increase in energetic costs of specific…

'Heike Lutermann' 'Matty Knight'] The distribution of parasites among hosts is often characterised by a high degree of heterogeneity with a small number of hosts harbouring the majority of parasites. Such patterns of aggregation have been linked to variation in host exposure and susceptibility as well as parasite…

'Gert Van der Auwera' 'Prashant Kumar' 'Mallikarjuna Rao Gedda' 'Tulika Kumari Rai' 'Epco Hasker' 'Shyam Sundar' 'Marleen Boelaert'] Background In the endgame of the elimination initiative of visceral leishmaniasis (VL) on the Indian subcontinent, one of the main questions remaining is whether asymptomatically infected…

'Wellington Francisco Rodrigues' 'Maria Tays Mendes' 'Carlo José Freire de Oliveira' 'Javier Emílio Lazo Chica'] Background Chagas disease is caused by the protozoan Trypanosoma cruzi and is characterized by cardiac, gastrointestinal, and nervous system disorders. Although much about the pathophysiological process of…

'Jessica F Stephenson'] Title: Abstract Choosing to mate with an infected partner has several potential fitness costs, including disease transmission and infection-induced reductions in fecundity and parental care. By instead choosing a mate with no, or few, parasites, animals avoid these costs and may also obtain…

Title: Graphical abstract
Pichet Ruenchit, Raul Colodner
Conventional methods such as microscopy have been used to diagnose parasitic diseases and medical conditions related to arthropods for many years. Some techniques are considered gold standard methods. However, their limited sensitivity, specificity, and accuracy, and the need for costly reagents and high-skilled…

Although parasites make up a substantial proportion of the biotic component of ecosystems, in terms of both biomass and number of species, they are rarely considered in conservation planning, except where they are thought to pose a threat to the conservation of their hosts. In this review, we address a number of…

Foodborne trematodes target their hosts, including humans, by residing in tasty food items. Lung flukes of the genus Paragonimus are no exception. Humans like to eat crabs and crayfish, often raw or incompletely cooked. If these crustaceans harbour metacercariae of a Paragonimus species, then human infection…
