Climate change is a well-documented driver of both wildlife extinction and disease emergence, but the negative impacts climate on parasite diversity are undocumented. We compiled most comprehensive spatially explicit data set available for parasites, projected range shifts in changing climate, estimated rates eight major clades. On basis 53,133 occurrences capturing geographic ranges 457 species, conservative model projections suggest that 5 to 10% these species committed by 2070 from...
How many parasites are there on Earth? Here, we use helminth to highlight how little is known about parasite diversity, and insufficient our current approach will be describe the full scope of life Earth. Using largest database host–parasite associations one world’s collections, estimate a global total roughly 100 000–350 000 species endoparasites vertebrates, which 85–95% unknown science. The amphibians reptiles remain most poorly described, but majority undescribed probably birds bony...
Species of Placobdella have been the frequent subject revisionary and alpha-taxonomy in past 2 decades. Recent molecular analyses introduced uncertainty about taxonomic status several broadly distributed morphologically variable species, including picta (Verrill 1872), compounded by incomplete original descriptions reliant upon characters that are no longer unique comparison to modern congeners. We assessed specimens P. identify any distinct phylogenetic entities align with our morphological...
Medicinal leeches became infamous for their utility in bloodletting popularized the 19th century, and have seen a recent resurgence post-operative treatments flap replantation surgeries, terms of characterization salivary anticoagulants. Notorious throughout world, quintessential leech family Hirudinidae has been taken granted to be monophyletic, as non-bloodfeeding Haemopidae. This study is first evaluate molecular evidence from hirudinid haemopid manner that encompasses global scope...
Understanding how microbiomes affect host resistance, parasite virulence, and parasite-associated diseases requires a collaborative effort between parasitologists, microbial ecologists, virologists, immunologists. We hereby propose the Parasite Microbiome Project to bring together researchers with complementary expertise study role of microbes in host-parasite interactions. Data from will help identify mechanisms driving microbiome variation parasites infected hosts that is associated...
With more than 700 described species, leeches include morphological, physiological, and behavioral diversity occur in terrestrial aquatic habitats, including freshwater, estuarine, marine ecosystems. Leeches inhabit a number of extreme environments, extremes temperature, moisture, salinity, pressure, light, pollution. In some cases, environments have specialized or adaptations to survive these conditions, yet unique are not apparent species. that inhospitable habitats one branch family leech...
Sucking lice are obligate parasites of eutherian mammals and generally considered to be host-specific parasites. Molecular investigations have found that some current louse taxonomy is incorrect does not reflect the relationships among families species. Western chipmunks (23 species Tamias) eastern chipmunk (Tamias striatus) infested by 2 different Hoplopleura sucking lice, arboricola erratica. has been on 19 23 western species, H. erratica only recorded as a parasite T. striatus. We...
Background Leeches have gained a fearsome reputation by feeding externally on blood, often from human hosts. Orificial hirudiniasis is condition in which leech enters body orifice, most the nasopharyngeal region, but there are many cases of leeches infesting eyes, urethra, vagina, or rectum. Several species particularly Africa and Asia well-known for their propensity to afflict humans. Because has not previously been any data suggesting close relationship such geographically disparate...

Phylogeny of macrophagous leeches (Hirudinea, Clitellata) based on molecular data and evaluation the barcoding locus. — Zoologica Scripta , 40 194–203. The phylogenetic relationships leech species are studied using two mitochondrial [cytochrome c oxidase subunit I (COI) 12S rDNA] nuclear (28S rDNA 18S rDNA) markers. complete dataset analysed in this study included 49 terminals 5540 aligned...
Mesobdella lineata, a small terrestrial species of leech from southern Africa, originally placed in the family Haemadipsidae, is redescribed based on internal and external morphological characters holotype additional material collected 1975. The placement this South American genus basis seemingly triannulate midbody somites found to be erroneous as are five-annulate. Mesobdelh lineata has neither midventral nephridial pore, synapomorphy Xerobdellidae, nor posteriolateral auricles...
SUMMARY The evolutionary history of leeches is employed as a general framework for understanding more than merely the systematics this charismatic group annelid worms, and serves basis blood-feeding related correlates ranging from specifics gut-associated bacterial symbionts to salivary anticoagulant peptides. A variety medicinal leech families were examined intraluminal crop symbionts. Species Aeromonas Bacteroidetes characterized with DNA gyrase B 16S rDNA. isolates found be much...
Leeches (Hirudinida) comprise a charismatic, yet often maligned group of organisms. Despite their ecological, economic, and medical importance, general consensus on the phylogenetic relationships major hirudinidan lineages is lacking. This absence consistent, robust phylogeny early-diverging has hindered our understanding underlying processes that enabled evolutionary diversification this clade. Here, we used an anchored hybrid enrichment-based phylogenomic approach, capturing hundreds loci...

Nematode parasites were encountered in kosher-certified fish meat and roe, the question was raised as to whether or not these food products kosher concerns preparation standards—a matter that pertains identity and, by extension, life cycle of parasites. To ascertain identities parasitic nematodes, given distorted damaged nature specimens, molecular techniques applied form DNA barcoding. our knowledge, this is first application technique an obviously cultural concern opposed one health...
Phylogenetic analyses of the leech family Macrobdellidae were accomplished with all nominal species in save one. A total 17 specimens nine ingroup analysed, along four outgroup taxa. Twenty‐two morphological characters based on jaw dentition, sexual anatomy, and external morphology failed to provide a resolution for many relationships family. DNA sequence data from nuclear 18S rDNA, 28S mitochondrial 12S cytochrome c oxidase subunit I examined separately combination characters. The resulting...
Morphological examination of novel specimens paruterinid cestodes from passerine birds Brazil and Chile museum Paraguay revealed two new species: Anonchotaenia prolixa sp. n. Elaenia albiceps chilensis Hellmayr Chile, vaslata Tyrannus melancholicus (Vieillot) (type host) Myiodynastes maculatus (Statius Muller) Paraguay. The generic diagnosis Conn, 1900 is amended, prompted by the presence armed cirrus elongated sac A. prolixa. Two species were redescribed: brasiliensis Fuhrmann, 1908...
A new species of the genus Hirudinaria from Thailand is distinguished its congeners by dorsal colour pattern and reproductive structures. Scanning electron microscopy provided novel information on jaw morphology bpling, sp. nov. also previously described manillensis. During study, name in reference to leeches was found be a homonym and, this case, precedence reversed. Phylogenetic analyses based nuclear genes 18S rDNA 28S as well mitochondrial 12S cytochrome c oxidase I, supported nested...
A new marine leech is herein described from specimens infecting the external surfaces, including mouth and cloaca, of banded guitarfish, Zapteryx exasperate, captured in Gulf California eastern Pacific Ocean off coast San Diego, California. The assigned to Austrobdella by possessing continuous contractile coelomic channels that lie outside somatic musculature along lateral edges urosome (marginal lacunae), clitellar gland cells densely packed urosome, 5 pairs testisacs, 6-annulate mid-body...
The complete holdings of Macrobdella species at the Smithsonian's National Museum Natural History were examined and identity 4 specimen lots redetermined. One these was redetermined as sestertia represents first report this from New Hampshire. Prior to report, only known a few occurrences in eastern Massachusetts Maine. This is also be found sympatry with decora, more common congener widespread distribution.
