Summary

Background

Malaria in the eastern Greater Mekong subregion has declined to historic lows. Countries in the Greater Mekong subregion are accelerating malaria elimination in the context of increasing antimalarial drug resistance. Infections are now increasingly concentrated in remote, forested foci. No intervention has yet shown satisfactory efficacy against forest-acquired malaria. The aim of this study was to assess the efficacy of malaria chemoprophylaxis among forest goers in Cambodia.

Methods

We conducted an open-label, individually randomized controlled trial in Cambodia, which recruited participants aged 16–65 years staying overnight in forests. Participants were randomly allocated 1:1 to antimalarial chemoprophylaxis, a 3-day …

Worldwide Host Associations Of The Tick Genus Ixodes Suggest Relationships Based On Environmental Sharing Rather Than On Co-Phylogenetic Events, Agustín Estrada-Peña, Alberto A. Guglielmone, Santiago Nava

Harold W. Manter Laboratory: Library Materials

Abstract

Background

This study aims to capture how ticks of the genus Ixodes gained their hosts using network constructs. We propose two alternative hypotheses, namely, an ecological background (ticks and hosts sharing environmentally available conditions) and a phylogenetic one, in which both partners co-evolved, adapting to existing environmental conditions after the association took place.

Methods

We used network constructs linking all the known pairs of associations between each species and stage of ticks with families and orders of hosts. Faith’s phylogenetic diversity was used to evaluate the phylogenetic distance of the hosts of each species and changes occurring in the …

Genomic Approaches To Uncovering The Coevolutionary History Of Parasitic Lice [Review], Kevin P. Johnson

Harold W. Manter Laboratory: Library Materials

Next-generation sequencing technologies are revolutionizing the fields of genomics, phylogenetics, and population genetics. These new genomic approaches have been extensively applied to a major group of parasites, the lice (Insecta: Phthiraptera) of birds and mammals. Two louse genomes have been assembled and annotated to date, and these have opened up new resources for the study of louse biology. Whole genome sequencing has been used to assemble large phylogenomic datasets for lice, incorporating sequences of thousands of genes. These datasets have provided highly supported trees at all taxonomic levels, ranging from relationships among the major groups of lice to those among …

Circling The Drain: The Extinction Crisis And The Future Of Humanity, Rodolfo Dirzo, Gerardo Ceballos, Paul R. Ehrlich

Harold W. Manter Laboratory: Library Materials

Humanity has triggered the sixth mass extinction episode since the beginning of the Phanerozoic. The complexity of this extinction crisis is centered on the intersection of two complex adaptive systems: human culture and ecosystem functioning, although the significance of this intersection is not properly appreciated. Human beings are part of biodiversity and elements in a global ecosystem. Civilization, and perhaps even the fate of our species, is utterly dependent on that ecosystem’s proper functioning, which society is increasingly degrading. The crisis seems rooted in three factors. First, relatively few people globally are aware of its existence. Second, most people who …

Diversity And Phylogenetic Relationships Of ‘Tetraphyllidean’ Clade 3 (Cestoda) Based On New Material From Orectolobiform Sharks In Australia And Taiwan, Janine N. Caira, Kirsten Jensen

Harold W. Manter Laboratory: Library Materials

In an effort to expand knowledge of Clade 3—one of the ten clades that compose the non-monophyletic order ‘Tetraphyllidea’ all current members of which parasitise orectolobiform sharks—we targeted species of orectolobiform sharks that had not previously been examined for ‘tetraphyllidean’ cestodes. That work led to the discovery of three new species off Australia and Taiwan. Ambitalveolus gen. n. was erected to accommodate these species. Ambitalveolus costelloae gen. n. et sp. n., Ambitalveolus kempi sp. n., and Ambitalveolus penghuensis sp. n. differ from one another in scolex size, genital pore position, and number of marginal loculi, proglottids, and testes. Among ‘tetraphyllideans’, …

First Detection Of Colletotrichum Fructicola (Ascomycota) On Horsehair Worms (Nematomorpha), Mattia De Vivo, Wen-Hong Wang, Ko-Hsuan Chen, Jen-Pan Huang

Harold W. Manter Laboratory: Library Materials

Fungal members of Colletotrichum (Ascomycota) were found to be associated with Chordodes formosanus, one of the three currently known horsehair worm (Nematomorpha) species in Taiwan. The fungi were identified as Colletotrichum fructicola, which is mostly known as a plant pathogen, through the use of the nuclear ribosomal internal transcribed spacer and partial large subunit (nrITS + nrLSU) and glyceraldehyde-3-phosphate dehydrogenase (GAPDH) DNA sequences. To our knowledge, this report represents both the first records for Colletotrichum associated with hairworms and for fungi on Nematomorpha. These findings expand the knowledge on the ecological relationships of both clades.

Global Distribution, Host Range And Prevalence Of Trypanosoma Vivax: A Systematic Review And Meta-Analysis, Eyerusalem Fetene, Samson Leta, Fikru Regassa, Philippe Büscher

Harold W. Manter Laboratory: Library Materials

Background

Trypanosomosis caused by Trypanosoma vivax is one of the diseases threatening the health and productivity of livestock in Africa and Latin America. Trypanosoma vivax is mainly transmitted by tsetse fies; however, the parasite has also acquired the ability to be transmitted mechanically by hematophagous dipterans. Understanding its distribution, host range and prevalence is a key step in local and global efforts to control the disease.

Methods

The study was conducted according to the methodological recommendations of the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) checklist. A systematic literature search was conducted on three search engines, namely PubMed, …

Taxonomy Of Echinostoma Revolutum And 37-Collar-Spined Echinostoma Spp.: A Historical Review, Jong-Yil Chai, Jaeeun Cho, Taehee Chang, Bong-Kwang Jung, Woon-Mok Sohn

Harold W. Manter Laboratory: Library Materials

Echinostoma flukes armed with 37 collar spines on their head collar are called as 37-collar-spined Echinostoma spp. (group) or ‘Echinostoma revolutum group’. At least 56 nominal species have been described in this group. However, many of them were morphologically close to and difficult to distinguish from the other, thus synonymized with the others. However, some of the synonymies were disagreed by other researchers, and taxonomic debates have been continued. Fortunately, recent development of molecular techniques, in particular, sequencing of the mitochondrial (nad1 and cox1) and nuclear genes (ITS region; ITS1-5.8S-ITS2), has enabled us to obtain highly …

Vertebrates On The Brink As Indicators Of Biological Annihilation And The Sixth Mass Extinction, Gerardo Ceballos, Paul R. Ehrlich, Peter H. Raven

Harold W. Manter Laboratory: Library Materials

The ongoing sixth mass species extinction is the result of the destruction of component populations leading to eventual extirpation of entire species. Populations and species extinctions have severe implications for society through the degradation of ecosystem services. Here we assess the extinction crisis from a different perspective. We examine 29,400 species of terrestrial vertebrates, and determine which are on the brink of extinction because they have fewer than 1,000 individuals. There are 515 species on the brink (1.7% of the evaluated vertebrates). Around 94% of the populations of 77 mammal and bird species on the brink have been lost in …

Hyperparasitic Spore-Forming Eukaryotes (Microsporidia, Haplosporidia, And Myxozoa) Parasitizing Trematodes (Platyhelminthes), Yuliya Ya. Sokolova, Robin M. Overstreet

Harold W. Manter Laboratory: Library Materials

ABSTRACT

Trematodes serve as outstanding hosts for a variety of parasites. This paper restricts those parasites to three groups of non-related taxa parasitizing trematodes and forming invasive spores similar in external morphology, which is why in the past these three groups of parasitic eukaryotes were united into the taxon “Sporozoa” (Kudo, 1924). (1) Trematode-infecting microsporidia (type Microsporidia Balbiani, 1882: Rozellomycota: Holomycota) are represented by more than 30 species. Among those, the species with sequenced barcode (SSU rDNA) are phylogenetically associated with either microsporidia from invertebrates, as the species of the genus Unikaryon (7 species), or fish microsporidia, as the species …

Efficient Coi Barcoding Using High Throughput Single-End 400 Bp Sequencing, Chentao Yang, Yuxuan Zheng, Shangjin Tan, Guanliang Meng, Wei Rao, Caiqing Yang, David G. Bourne, Paul A. O'Brien, Junqiang Xu, Sha Liao, Ao Chen, Xiaowei Chen, Xinrui Jia, Ai-Bing Zhang, Shanlin Liu

Harold W. Manter Laboratory: Library Materials

Background

Over the last decade, the rapid development of high-throughput sequencing platforms has accelerated species description and assisted morphological classification through DNA barcoding. However, the current highthroughput DNA barcoding methods cannot obtain full-length barcode sequences due to read length limitations (for example, a maximum read length of 300 bp for the Illumina’s MiSeq system), or are hindered by a relatively high cost or low sequencing output (e.g. a maximum number of eight million reads per cell for the PacBio’s SEQUEL II system).

Results

Pooled cytochrome c oxidase subunit I (COI) barcodes from individual specimens were sequenced on the …

Harold W. Manter Laboratory: Library Materials

Natural history collections are leading successful large-scale projects of specimen digitization (images, metadata, DNA barcodes), thereby transforming taxonomy into a big data science. Yet, little effort has been directed towards safeguarding and subsequently mobilizing the considerable amount of original data generated during the process of naming 15,000–20,000 species every year. From the perspective of alpha-taxonomists, we provide a review of the properties and diversity of taxonomic data, assess their volume and use, and establish criteria for optimizing data repositories. We surveyed 4,113 alpha-taxonomic studies in representative journals for 2002, 2010, and 2018, and found an increasing yet comparatively limited use …

Harold W. Manter Laboratory: Library Materials

The data presented in this article are related to a previously published research article titled The timing of worm exclusion in dogs repeatedly infected with the cestode Echinococcus multilocularis (Kouguchi et al. 2016). This data describe a comparison of worm exclusion in the early stage of infection (1 day and 6 days post-infection) between dogs infected for the first time (control group) and dogs repeatedly infected with the parasite 4 times (repeated infection groups). We observed that 6 days post reinfection, the number of adult worms in repeated-infection groups decreased by 88.7% compared with the control group. Histological analysis comparison …

Novel Information On The Morphology, Phylogeny And Distribution Of Camallanid Mematodes From Marine And Freshwater Hosts In South Africa, Including The Description Of Camallanus Sodwanaensis N. Sp., Roman Svitin, Marliese Truter, Olena Kudlai, Nico J. Smit, Louis Du Preez

Harold W. Manter Laboratory: Library Materials

Four species of previously known nematodes from the family Camallanidae were found from different hosts in South Africa: Batrachocamallanus xenopodis from the frog Xenopus muelleri, Paracamallanus cyathopharynx, and Procamallanus pseudolaeviconchus from the catfish Clarias gariepinus and Spirocamallanus daleneae from the catfish Synodontis zambezensis. In the material collected from various marine fishes, several specimens of nematodes from the genus Camallanus clearly differed from all previously known species. Based on morphological differences these specimens are assigned to a new species, C. sodwanaensis. Molecular data of 18S and 28S rDNA and COI sequences are provided for the collected species …

A New Species Of Gordius (Phylum Nematomorpha) From Terrestrial Habitats In North America, Christina Anaya, Andreas Schmidt-Rhaesa, Ben Hanelt, Matthew G. Bolek

Harold W. Manter Laboratory: Library Materials

Freshwater hairworms (class Gordiida) are members of the phylum Nematomorpha that use terrestrial arthropods as definitive hosts but reside as free-living adult worms in rivers, lakes, or streams. The genus Gordius consists of 90 described species, of which three species were described from freshwater habitats in North America. In this paper we describe a new species of Gordius from terrestrial habitats in Oklahoma, Texas, and Louisiana, United States. Oddly, each year hundreds of adult free-living worms appear after bouts of heavy rain on streets, sidewalks, and lawns during the winter season, when terrestrial arthropod hosts are not active. The new …

Scaphanocephalus-Associated Dermatitis As The Basis For Black Spot Disease In Acanthuridae Of St. Kitts, West Indies, Michelle M. Dennis, Adrien Izquierdo, Anne Conan, Kelsey Johnson, Solenne Giardi, Paul Frye, Mark A. Freeman

Harold W. Manter Laboratory: Library Materials

Acanthurus spp. of St. Kitts and other Caribbean islands, including ocean surgeonfish A. bahianus, doctorfish A. chirurgus, and blue tang A. coeruleus, frequently show multifocal cutaneous pigmentation. Initial reports from the Leeward Antilles raised suspicion of a parasitic etiology. The aim of this study was to quantify the prevalence of the disease in St. Kitts’ Acanthuridae and describe its pathology and etiology. Visual surveys demonstrated consistently high adjusted mean prevalence at 3 shallow reefs in St. Kitts in 2017 (38.9%, 95% CI: 33.8−43.9) and 2018 (51.5%; 95% CI: 46.2−56.9). There were no differences in …

Fresh Fruits, Vegetables, And Mushrooms As Transmission Vehicles For Echinococcus Multilocularis In Highly Endemic Areas Of Poland: Reply To Concerns, Anna Lass, Beata Szostakowska, Przemysław Myjak, Krzystof Korzeniewski

Harold W. Manter Laboratory: Library Materials

Echinococcus multilocularis is a tapeworm that may cause alveolar echinococcosis (AE), one of the most dangerous parasitic zoonoses. As in the case of other foodborne diseases, unwashed fruits and vegetables, contaminated with dispersed forms of E. multilocularis, may serve as an important transmission route for this parasite. In this article, we reply to the incorrect interpretation of results of our study concerning the detection of E. multilocularis DNA in fresh fruit, vegetable and mushroom samples collected from the highly endemic areas of the Warmia-Masuria Province, Poland, to dispel any doubts. The accusations formulated by the commentators concerning …

Echinococcus Multilocularis In Foxes And Raccoon Dogs: An Increasing Concern For Baltic Countries, Guna Bagrade, Gunita Deksne, Zanda Ozoliņa, Samantha Jane Howlett, Maria Interisano, Adriano Casulli, Edoardo Pozio

Harold W. Manter Laboratory: Library Materials

Background

In Europe, the life cycle of Echinococcus multilocularis is predominantly sylvatic, involving red foxes (Vulpes vulpes) as the main definitive hosts and rodents such as muskrats and arvicolids as intermediate hosts. The parasite is the etiological agent of human alveolar echinococcosis, a malignant zoonotic disease caused by the accidental ingestion of eggs shed by definitive hosts in their feces. The aims of this study were to investigate the prevalence of E. multilocularis in red foxes and raccoon dogs (Nyctereutes procyonoides) and to study the environmental factors favoring the perpetuation of the parasite in Latvia. …

Taxonomy And Molecular Epidemiology Of Echinococcus Granulosus Sensu Lato, Thomas Romig, Dennis Ebi, Marion Wassermann

Harold W. Manter Laboratory: Library Materials

Echinococcus granulosus, formerly regarded as a single species with a high genotypic and phenotypic diversity, is now recognized as an assemblage of cryptic species, which differ considerably in morphology, development, host specificity (including infectivity/pathogenicity for humans) and other aspects. This diversity is reflected in the mitochondrial and nuclear genomes and has led to the construction of phylogenetic trees and hypotheses on the origin and geographic dispersal of various taxa. Based on phenotypic characters and gene sequences, E. granulosus (sensu lato) has by now been subdivided into E. granulosus sensu stricto (including the formerly identified genotypic variants G1-3), …

Evolution Of Hematophagous Habit In Triatominae (Heteroptera: Reduviidae), Fernando Otálora-Luna, Antonio J. Pérez-Sánchez, Claudia Sandoval, Elis Aldana

Harold W. Manter Laboratory: Library Materials

All members of Triatominae subfamily (Heteroptera: Reduviidae), potential vectors of Trypanosoma cruzi, etiologic agent of the Chagas disease, feed on blood. Through evolution, these bugs have fixed special morphological, physiological, and behavioral aptations (adaptations and exaptations) adequate to feed on blood. Phylogeny suggests that triatomines evolved from predator reduvids which in turn descended from phytophagous hemipterans. Some pleisiomorphic traits developed by the reduvid ancestors of the triatomines facilitated and modeled hematophagy in these insects. Among them, mouthparts, saliva composition, enzymes, and digestive symbionts are the most noticeable. However, the decisive step that allowed the shift from predation to hematophagy …

Harold W. Manter Laboratory: Library Materials

Abstract

Background

Cystic echinococcosis (CE) is a globally distributed cestode zoonosis that causes hepatic cysts. Although Echinococcus granulosus sensu stricto (s.s.) is the major causative agent of CE worldwide, recent molecular epidemiological studies have revealed that E. canadensis is common in countries where camels are present. One such country is Mongolia.

Methodology/Principal Findings

Forty-three human hepatic CE cases that were confirmed histopathologically at the National Center of Pathology (NCP) in Ulaanbaatar (UB) were identified by analysis of mitochondrial cox1 gene as being caused by either E. canadensis (n = 31, 72.1%) or E. granulosus s.s. ( …

Some Aspects Of The Biology Of Monogenean (Platyhelminth) Parasites Of Marine And Freshwater Fishes, Graham C. Kearn

Harold W. Manter Laboratory: Library Materials

Müller was the first to describe a monogenean, collected from the skin of the halibut (Hippoglossus hippoglossus). However, he regarded the parasite as a leech and named it Hirudo hippoglossi. It was not until 1858 that its status as a monogenean was established by van Beneden and named Epibdella (now Entobdella) hippoglossi. Van Beneden published a detailed and accurate description of the parasite and one of his excellent illustrations is reproduced here. Entobdella hippoglossi is one of the largest monogeneans, measuring up to 2 cm in length. It has a smaller relative, measuring 5 to …

Pentastomids Of Wild Snakes In Australia, Crystal Kelehear, David M. Spratt, Denis O'Meally, Richard Shine

Harold W. Manter Laboratory: Library Materials

Pentastomids are endoparasites of the respiratory system of vertebrates, maturing primarily in carnivorous reptiles. Adult and larval pentastomids can cause severe pathology resulting in the death of their intermediate and definitive hosts. The study of pentastomids is a neglected field, impaired by risk of zoonoses, difficulties in species identification, and life cycle complexities. We surveyed wild snakes in the tropics of Australia to clarify which host species possess these parasites, and then sought to identify these pentastomids using a combination of morphological and molecular techniques. We detected pentastomid infections in 59% of the 81 snakes surveyed. The ubiquity of pentastomid …
