Trinidad and Tobago united in 1898 and were made part of the British colony of Trinidad and Tobago in 1899. The colony became an independent state in 1962. Trinidad was so named by Columbus either because he arrived on Trinity Sunday or because three mountain peaks suggested the Holy Trinity. Tobago was given the name by Columbus from the Haitian tambaku, pipe, from the natives' habit of smoking tobacco leaves.

Helminth fauna of carnivores distributed in north-western Tohoku, Japan, with special reference to Mesocestoides paucitesticulus and Brachylaima tokudai. (1/41)

In the winter of 1998-1999, we collected parasitological data from 54 wild carnivores in the north-western part of Tohoku region, Japan. These consisted of 38 martens (Martes melampus melampus), 14 raccoon dogs (Nyctereutes procyonoides viverrinus) and 2 foxes (Vulpes vulpes japonica). Collected helminth parasites were 11 nematode, 10 trematode, 3 cestode, and a single acanthocephalan species, including 5 hitherto unknown species for this research area or the mainland of Japan (Honshu). Mesocestoides paucitesticulus was for the first time recorded from martens as well as from carnivores distributed in Honshu. Brachylaima tokudai originally recorded from Urotrichus talpoides in the central part of Honshu was for the first time found from a raccoon dog.  (+info)

Recent Studies on Neoechinorhynchus curemai Noronha, 1973 (Acanthocephala: Neoechinorhynchidae), in Prochilodus lineatus Valenciennes, 1836, from Volta Grande Reservoir, MG, Brazil. (2/41)

The present work described helminth parasites of curimbata, Prochilodus lineatus Valenciennes, 1836 from Volta Grande Reservoir, MG, Brazil. Eighteen fishes with average 46.7 +/- 1.1 cm length and 1,674.8 +/- 75.6 g weight were collected. Of the analysed fishes, 15 were parasitized with acanthocephalans in the intestine, showing a prevalence of 83.3%. The helminth was identified as Neoechinorhynchus curemai Noronha, 1973 (Acanthocephala: Neoechinorhynchidae). It differs from other species in dimension of characters and morphology. From the original description of N. curemai, it differs from the biggest dimension of testis, elongated cement gland, nucleated lemnisci, eggs size, larger proboscis hooks length in the middle and in the third circle in males and larger hooks in the anterior circle in females. A smaller percentage occupied by the reproductive system in female trunk was reported. The observation of paratypes of N. curemai of Noronha (1973) showed a great similarity with those of the present work. This fact complements the helminth description from elsewhere.  (+info)

Gastrointestinal parasites and prey items from a mass stranding of false killer whales, Pseudorca crassidens, in Rio Grande do Sul, Southern Brazil. (3/41)

The gastrointestinal tract of 14 false killer whales, 6 males and 8 females, stranded in June 1995 in southern Brazil, with total standard lengths from 338 to 507 cm, were analysed for endoparasites and food items. A pregnant female had a male foetus of 77.5 cm. Parasites were found in all 14 false killer whales. The nematode Anisakis simplex (Rudolphi, 1809) was found in the stomach of 57% of the animals and the acanthocephalan Bolbosoma capitatum (Linstow, 1889) Porta, 1908 was present in the intestine of all specimens and showed densities up to 600 m-1. An unidentified cestode (Tethrabothridae) was found also in the intestines of 14% of the individuals. The high infections of B. capitatum and A. simplex were not directly related with the cause of death. In the stomachs of four females, beaks of at least eight specimens of the oceanic and epipelagic species Ommastrephes bartramii (Lesueur, 1821) were found, with mantle lengths ranging from 189.8 to 360.9 mm. The distribution of O. bartramii in the coast of Rio Grande do Sul is consistent with false killer whales feeding in continental shelf waters.  (+info)

Rates of nucleotide substitution in sexual and anciently asexual rotifers. (4/41)

The class Bdelloidea of the phylum Rotifera is the largest well studied eukaryotic taxon in which males and meiosis are unknown, and the only one for which these indications of ancient asexuality are supported by cytological and molecular genetic evidence. We estimated the rates of synonymous and nonsynonymous substitutions in the hsp82 heat shock gene in bdelloids and in facultatively sexual rotifers of the class Monogononta, employing distance based and maximum likelihood methods. Relative-rate tests, using acanthocephalan rotifers as an outgroup, showed slightly higher rates of nonsynonymous substitution and slightly lower rates of synonymous substitution in bdelloids as compared with monogononts. The opposite trend, however, was seen in intraclass pairwise comparisons. If, as it seems, bdelloids have evolved asexually, an equality of bdelloid and monogonont substitution rates would suggest that the maintenance of sexual reproduction in monogononts is not attributable to an effect of sexual reproduction in limiting the load of deleterious nucleotide substitutions.  (+info)

Digenea and acanthocephala of elasmobranch fishes from the southern coast of Brazil. (5/41)

New records for helminth species recovered from elasmobranch fishes in Brazil are established. Digenean and acanthocephalan parasites of elasmobranch fishes are reported from the southern coast of Brazil: Otodistomum veliporum (Creplin, 1837) Stafford, 1904 (Digenea: Azygiidae) in the stomach and spiral valve of Dipturus trachydermus and in the spiral valve of Squatina sp. Cystacanths and juveniles of the acanthocephalans Corynosoma australe Johnston, 1937 and Corynosoma sp., in the spiral valve of Squatina sp., Galeorhinus galeus and Hexanchus griseus and in the stomach of Squalus megalops; a juvenile of Gorgorhynchus sp., in the spiral valve of Sphyrna zygaena. Dipturus trachydermus and Squatina sp. are new host records for O. veliporum. Digeneans and acanthocephalans are reported for the first time parasitizing elasmobranch fishes in Brazil.  (+info)

Electrophysiology of acanthocephalan body wall muscles. (6/41)

Body wall muscles of an acanthocephalan Macracanthorhynchus hirudinaceus were studied by means of scanning and light microscopy and intracellular recording of potentials. Three types of spontaneous potential changes were found: larger (L) potentials which usually exhibited overshoot and were as large as 65 mV; smaller symmetric (A) potentials approximately 15 mV in amplitude; and even smaller asymmetric (S) potentials which sometimes reached 10 mV. The potentials recorded depended upon the position of the electrode in the anterior-posterior, as well as the medial-lateral, axis. Tetrodotoxin eliminated L but not S potentials. Ouabain lengthened the time for depolarization of L potentials and depolarized the membrane potentials. It is suggested that the rete system activates the body wall muscles in Acanthocephala.  (+info)

Effect of Pomphorhynchus laevis (Acanthocephala) on putative neuromodulators in the intestine of naturally infected Salmo trutta. (7/41)

Immunohistochemical and pathological studies were carried out on the digestive tract of parasitized and uninfected specimens of Salmo trutta (L.). A total of 124 brown trout were collected on several occasions from 3 tributaries of the Brenta River, northern Italy. Twenty-eight individuals of S. trutta (22.6%) were parasitized with Pomphorhynchus laevis (Miller, 1776). The occurrence of P. laevis in the trout gut significantly increased the number of endocrine cells immunoreactive to calcitonin gene-related peptide (CGRP), beta-endorphin, met-enkephalin, neuropeptide Y (NPY) and Substance P (SP) antisera. Moreover, bombesin-, cholecistokinin-8- (CCK-8), leu-enkephalin- and serotonin- (5-HT)-like immunoreactive cells were less numerous in the intestine of the parasitized brown trout. A strong positive immunoreactivity was observed in nerve fibres and neurones of the myenteric plexus of the parasitized fish; the antisera involved in this positive reactivity were bombesin, met-enkephalin, SP and vasoactive intestinal peptide (VIP). More neurones immunoreactive to anti-CGRP and anti-5-HT sera were noted in the myenteric plexus and in the inner layer of the tunica muscularis of the infected fish. Most of the above-mentioned neuromodulators are known to control gut motility, digestive/absorptive processes, as well as the immune response. The changes induced by parasites in the neuroendocrine system of the brown trout are discussed.  (+info)

Helminth parasites of the southern sea otter Enhydra lutris nereis in central California: abundance, distribution and pathology. (8/41)

From October 1997 to May 2001, the gastrointestinal tracts from 162 beach-cast southern sea otters Enhydra lutris nereis were examined for helminth parasites and associated lesions. Carcasses were collected opportunistically in central California between Pt. San Pedro and Pt. Arguello. The primary goals of this study were to examine spatial and temporal variability in mortality due to parasite infection, identify factors associated with increased risk of infection, and illustrate the process of intestinal perforation by Profilicollis spp. Two genera and 4 species of acanthocephalans (Profilicollis altmani, P. kenti, P. major, Corynosoma enhydri) were found in 46.3% (Profilicollis spp.) and 94.4% (C. enhydri) of the carcasses examined. Three species of Digenea (Microphallus pirum, M. nicolli, Plenosoma minimum) were found in 47% of carcasses, at times in massive numbers (> 3000 per cm2). This is the first report of the latter 2 species from the sea otter. Mortality resulting from infection by Profilicollis spp. occurred in 13.0% (n = 21) of sampled carcasses, either directly, due to perforation of the intestinal wall and peritonitis (9.9%, n = 16), or indirectly, due to inhibition of host nutrient uptake or depletion of host energy reserves to fight chronic infections (3.1%, n = 5). The most massive infections (< 8760 parasites), and all cases of intestinal perforation occurred in carcasses infected by P. altmani and/or P. kenti. Mortality due to infection by Profilicollis spp. occurred more frequently among juvenile and old-adult females (chi2 = 17.479, df = 9, p = 0.045) from sand and mixed habitats in Monterey and Santa Cruz in the north of the sea otter range (chi2 = 9.84, df = 4, p = 0.045). Spatial differences in sea otter mortality coincided with the relative distributions of Profilicollis altmani, P. kenti, and P. major, and may reflect differences in sea otter diet, or differences in intensity of infection in intermediate hosts. Mortality rate due to infection by Profilicollis spp. decreased between 1998 and 2001, though differences were not significant (chi2 = 3.983, df = 3, p = 0.40), and may vary on multi-year cycles due to environmental factors such as density of definitive hosts (e.g. the surf scoter Melanitta perspicillata), or El Nino. Corynosoma enhydri did not cause significant damage to the intestine of the host, even when present in great numbers.  (+info)

Acanthocephala - WikipediaAcanthocephala - Wikipedia
Acanthocephala (Greek ἄκανθος, akanthos, thorn + κεφαλή, kephale, head) is a phylum of parasitic worms known as acanthocephalans, thorny-headed worms, or spiny-headed worms, characterized by the presence of an eversible proboscis, armed with spines, which it uses to pierce and hold the gut wall of its host. Acanthocephalans have complex life cycles, involving at least two hosts, which may include invertebrates, fish, amphibians, birds, and mammals. About 1150 species have been described. The Acanthocephala were thought to be a discrete phylum. Recent genome analysis has shown that they are descended from, and should be considered as, highly modified rotifers. This finding is an example of molecular phylogenetics. This unified taxon is known as Syndermata. The earliest recognisable description of Acanthocephala - a worm with a proboscis armed with hooks - was made by Italian author Francesco Redi (1684). In 1771, Joseph Koelreuter proposed the name Acanthocephala. Philipp Ludwig ...

Checklist of acanthocephalan parasites of South AfricaChecklist of acanthocephalan parasites of South Africa
Twenty-one species of acanthocephalans, representative of thirteen genera from ten families of seven orders and three classes, are included in this updated checklist of acanthocephalans in South Africa. Although South Africa appears to have a less diverse acanthocephalan fauna compared to some other countries such as Iran in Asia, or Brazil in South America, this is probably an artefact of fewer parasitological surveys.

The present study was undertaken to determine the incidence of helminth parasites in fishes with special reference to water quality parameters in Dal Lake and River Jhelum and correlate the observations. Water, fish, and parasite samples were collected during different seasons from various sites and processed. Three fish species, namely, Schizothorax niger Heckel 1838, Schizothorax esocinus Heckel 1838, and Schizothorax curvifrons Heckel 1838, were recovered from these water bodies. The physicochemical parameters temperature, dissolved oxygen, pH, and free carbon dioxide showed variation vis-à-vis the season and location of the stations in water bodies. Acanthocephalan parasite Pomphorhynchus kashmirensis Kaw 1941 (27.47%) and two intestinal cestodes Bothriocephalus acheilognathi Yamaguti 1934 (30.63%) and Adenoscolex oreini Fotedar 1958 (32.43%) were recovered from all the three species of Schizothorax. All the three parasites showed higher prevalence during summer and the least prevalence ...
Alosa pseudoharengus, Alewife : fisheries, baitAlosa pseudoharengus, Alewife : fisheries, bait
Movement of schooling adults apparently restricted to coastal areas proximal to natal estuaries (Ref. 4639). They migrate up rivers and even small streams to spawn in lakes and quiet stretches of rivers, then return to sea shortly after spawning (Ref. 4639); landlocked populations also ascend affluent rivers and streams. Larvae remain in vicinity of spawning grounds, forming schools at sizes less than 10 mm TL, within one to two weeks after hatching (Ref. 4639), then descend in summer and autumn or even as late as November or December. Feed on shrimps and small fishes; the young on diatoms, copepods and ostracods while in rivers. Utilized fresh, dried or salted, smoked and frozen; eaten fried (Ref. 9988). Also used for crab and lobster bait and sometimes for pet food (Ref. 9988). Parasites found are Acanthocephala, cestodes, trematodes and copepods. Overfishing, pollution and impassable dams cause the decline of stocks (Ref. 37032). ...

Encyclopedia of LifeEncyclopedia of Life
The major subgroups of animals are usually classified as phyla (singular: phylum). The higher classification of animals is still in flux, and scientists opinions on which groups should be given phylum status change as new information about the structure of the animal tree of life becomes available. So you may see that some of the groups listed here as phyla are classified differently elsewhere. For example, the spiny-headed worms, Acanthocephala used to be treated as a phylum, but research has shown that this group is probably nested within the phylum Rotifera, so it will probably disappear from modern lists of animal phyla. ...
Conflict over Host Manipulation | Proceedings of the Royal Society of London B: Biological SciencesConflict over Host Manipulation | Proceedings of the Royal Society of London B: Biological Sciences
The nematode Camallanus lacustris initially alters host behaviour to arguably reduce predation on its host before it reaches infectivity. Thereafter slight changes of host behaviour into the opposite direction occur. This follows a pattern previously predicted [45] and shown in other systems [13,15,32,46]. The manipulation by C. lacustris is similar to but more pronounced than that of the cestode Schistocephalus solidus in the same copepod host [13,32]. Nevertheless, host manipulation by C. lacustris and S. solidus result in a similar reduction of predation susceptibility [16]. Different complex life cycle parasites that exploit the same trophic link also adopt convergent life-history strategies [47], suggesting that their host manipulation should also cause similar host behaviour.. Once we have shown that there is conflict (be it between two manipulating or one manipulating and one not manipulating parasite), we focus on the outcome of this conflict. This is where our main findings are. In any ...
Cysteine protease - WikipediaCysteine protease - Wikipedia
Currently there is no widespread use of cysteine proteases as approved and effective anthelmintics but research into the subject is a promising field of study. Plant cysteine proteases isolated from these plants have been found to have high proteolytic activities that are known to digest nematode cuticles, with very low toxicity.[7] Successful results have been reported against nematodes such as Heligmosomoides bakeri, Trichinella spiralis, Nippostrongylus brasiliensis, Trichuris muris, and Ancylostoma ceylanicum; the tapeworm Rodentolepis microstoma, and the porcine acanthocephalan parasite Macracanthorynchus hirundinaceus.[8] A useful property of cysteine proteases is the resistance to acid digestion, allowing possible oral administration. They provide an alternative mechanism of action to current anthelmintics and the development of resistance is thought to be unlikely because it would require a complete change of structure of the helminth cuticle.

Cooperation and conflict in host-manipulating parasites | Proceedings of the Royal Society of London B: Biological SciencesCooperation and conflict in host-manipulating parasites | Proceedings of the Royal Society of London B: Biological Sciences
The existence of adaptive host manipulation by parasites has received increasing empirical support in recent years. Here I develop an optimality model of the extent of host manipulation, incorporating within-host group size, relatedness and a range of realistic cost-benefit functions. The model highlights the cooperative nature of host manipulation, and the potential for cheating this entails. When relatedness in parasite groups is minimal, manipulation is suppressed, but not eradicated, reflecting the importance of interhost selection. A distinctive threshold phenomenon is predicted for a wide range of parameter values. Below the group size threshold, manipulation is zero. Above the threshold, the predicted behaviour depends critically on the biological details of the individual-group interaction. The host-manipulation model is discussed in the light of two potential applications. If parasite group size is assumed to be a static characteristic of a parasite species or strain, the model ...

Molecular and morphological data regarding the relationships among the three classes of Rotifera (Bdelloidea, Seisonidea, and Monogononta) and the phylum Acanthocephala are inconclusive. In particular, Bdelloidea lacks molecular-based phylogenetic appraisal. I obtained coding sequences from the mitochondrial genomes of twelve bdelloids and two monogononts to explore the molecular phylogeny of Bdelloidea and provide insight into the relationships among lineages of Syndermata (Rotifera + Acanthocephala). With additional sequences taken from previously published mitochondrial genomes, the total dataset included nine species of bdelloids, three species of monogononts, and two species of acanthocephalans. A supermatrix of these 10-12 mitochondrial proteins consistently recovered a bdelloid phylogeny that questions the validity of a generally accepted classification scheme despite different methods of inference and various parameter adjustments. Specifically, results showed that neither the family

The Northern pike, Esox lucius, is a large, long-lived, top-predator fish species and occupies a broad range of aquatic environments. This species is on its way to becoming an important model organism and has the potential to contribute new knowledge and a better understanding of ecology and evolutionary biology. Very few studies have been done on the intestinal pathology of pike infected with helminths. The present study details the first Italian record of adult Acanthocephalus lucii reported in the intestine of E. lucius. A total of 22 pike from Lake Piediluco (Central Italy) were examined, of which 16 (72.7%) were infected with A. lucii. The most affected areas of gastrointestinal tract were the medium and distal intestine. The intensity of infection ranged from 1 to 18 parasites per host. Acanthocephalus lucii penetrated mucosal and submucosal layers which had a high number of mast cells (MCs) with an intense degranulation. The cellular elements involved in the immune response within the intestine

Focusing on feeding as an endpoint in ecotoxicological studies is a useful and sensitive tool to detect sub-lethal impacts on individual organisms with relevance to higher levels of organisation (i.e. population and ecosystem levels). Energy availability depends on feeding [[1],[2]], and the energy budget can be considered an indicator of the overall condition of an organism [[3]]. Feeding determines the health of a population because altered growth and reproduction can be instigated by an effect on feeding [[4]-[7]]. Furthermore, reduced feeding can, at weak levels, reduce the possibility of survival due to interference with further sub-lethal effects and, at strong levels, cause death. Beyond secondary impacts of effects on feeding at the population level, feeding activity can play a direct role at the ecosystem level due to its importance for nutrient cycling.. One group of organisms responsible for a high proportion of the nutrient cycling in freshwaters are detritivores like Gammarus due to ...

Parasite of the Day: February 2012Parasite of the Day: February 2012
Acanthocephalus dirus has a reproductive strategy that is unusual for its group - the acanthocephalans or the thorny-headed worms (Acantho = "thorns", Cephala = "head"). In fact it is unusual compared to most intestinal parasites. Unlike some tapeworms, which profligately cast off segments (each containing hundreds of eggs) into the wilderness with abandonment, A. dirus has rather different approach. The impetus that spurred on this piece of research were two separate observations: (1) fish that are infected with A. dirus do not have any worm eggs in their feces (unlike most animals infected with intestinal parasites) and (2) perfectly healthy and intact female worms were often expelled from the definitive host. What the researchers found was that instead of simply laying eggs that are expelled from the worm and from the host, a female A. dirus actually retains her eggs until she become completely bloated with them - at which point she exits gracefully from the host fishs digestive tract.

How much energy should manipulative parasites leave to their hosts to ensure altered behaviours? | Journal of Experimental...How much energy should manipulative parasites leave to their hosts to ensure altered behaviours? | Journal of Experimental...
Although host manipulation is likely to be costly for parasites, we still have a poor understanding of the energetic aspects underlying this strategy. It is traditionally assumed that physiological costs are inevitably associated with mechanisms evolved by parasites to induce the required changes in host behaviours. While most energetic expenditures of parasites relate primarily to bringing about the altered behaviours, manipulative parasites also have to consider the condition of their host during the manipulation. Here, we suggest that because of this trade-off, the energy required to accomplish parasite-induced behaviours may represent a key energetic constraint for parasites. Depending on the energetic expenditures specific to each type of manipulation, parasites should undergo selection to secure resources for their host to allow them to perform manipulated behaviours.. ...
Do schistosomes practice the art of host-manipulation? - BugBittenDo schistosomes practice the art of host-manipulation? - BugBitten
Parasites manipulating host behaviour is not a new story. There are lots of examples of parasites and parasitoids making their poor hosts do the most extraordinary things: grasshoppers purposefully jumping into water and drowning themselves, rats running towards cat urine smells, cockroaches walking into predator wasp lairs etc. This level of skilled "mind-control" would leave even our most talented illusionists agog with admiration and horror.. From a public and veterinary health point of view, the concept of host manipulation is of particular interest when it results in the increase of transmission of a disease. This has been suggested with mosquitoes and malaria parasites, where malaria infection in the mosquito leads to increased biting rates and subsequent spread of infection of the malaria parasite..

Hybridization Experiments and the Taxonomy of Gammarus (Amphipoda): a Contribution To the Understanding of Controversial...Hybridization Experiments and the Taxonomy of Gammarus (Amphipoda): a Contribution To the Understanding of Controversial...
In the last two decades, hybridization experiments were frequently used to elucidate the taxonomic position of populations belonging to the Gammarus pulex-group. Since these experiments did not always give adequate answers, genetic differentiation based on enzyme polymorphisms was investigated. The differentiation recorded was apparently neither consistent with morphological data nor with results from cross-breeding experiments. In order to explain the inconsistency of hybridization levels and genetic differentiation, a more detailed knowledge of the mechanisms enhancing various levels of reproductive isolation is necessary. Two new series of interpopulational hybridization experiments were carried out. Unlike in previous experiments it was not our first aim to determine the final outcome (positive or negative) of the crosses, but to obtain a more detailed analysis of all stages leading towards the final result. The animals were daily followed from the formation of precopulations until the hatching of

The Monty Hall Problem - Math ImagesThe Monty Hall Problem - Math Images
The question was originally proposed by a reader of "Ask Marilyn", a column in Parade Magazine in 1990. Marilyns correct solution, that switching doors was the best strategy, caused an uproar among mathematicians. While most people responded that switching should not matter, the contestants chances for winning in fact double if he switches doors. Part of the controversy, however, was caused by the lack of agreement on the statement of the problem itself. Most statements of the problem, including the one in Marilyns column, do not match the rules of the actual game show. This was a source of great confusion when the problem was first presented. The main ambiguities in the problem arise from the fact that it does not fully specify the hosts behavior. For example, imagine a host who wasnt required to always reveal a goat. The hosts strategy could be to open a door only when the contestant has selected the correct door initially. This way, the host could try to tempt the contestant to switch ...

Vse živali so heterotrofi, kar pomeni, da se neposredno ali posredno prehranjujejo s snovmi nastalimi v drugih organizmih.[10] Pogosto se naprej delijo na skupine, kot so zveri, herbivori, omnivori in paraziti.[11] Plenilstvo je biološka interakcija, kjer se plenilec (heterotrof, ki lovi) hrani s svojim plenom (organizem, ki je napaden).[12] Plenilec lahko ubije svoj plen zaradi hranjenja ali zaradi drugih vzrokov, vendar je posledica vedno smrt plena.[13] Drugi glavni način konzumiranja hrane imajo detritofagi, ki se hranijo z mrtvo organsko snovjo.[14] Včasih je težko ločevati ta dva načina prehranjevalnega vedenja, na primer kadar parazit preži na gostiteljski organizem in nanj leže jajčeca, tako da se potomstvo potem po izvalitvi lahko hrani z razpadajočim truplom. Medsebojni selekcijski pritiski, ki se ob tem pojavljajo, so pripeljali do evolucijske »oborožitvene tekme« med plenom in plenilcem, katere rezultat so različne protiplenilske prilagoditve in načini, kako jih ...

Characterization of the complete mitochondrial genome of Brentisentis yangtzensis Yu & Wu, 1989 (Acanthocephala, Illiosentidae)Characterization of the complete mitochondrial genome of Brentisentis yangtzensis Yu & Wu, 1989 (Acanthocephala, Illiosentidae)
The mitogenome of Brentisentis yangtzensis is 13,864 bp in length and has the circular structure typical of metazoans. It contains 36 genes: 22 transfer RNA genes (tRNAs), two ribosomal RNA genes (rRNAs) and 12 protein-encoding genes (PCGs). All genes are transcribed from the same strand. Thirteen overlapping regions were found in the mitochondrial genome. The overall A+T content of B. yangtzensis is 68.3% versus 31.7% of G+C content (A = 27.8%, T = 40.5%, C = 9.0%, G = 22.7%). B. yangtzenensis (Illiosentidae) and Leptorhynchoides thecatus (Rhadinorhynchidae) form a sister clade, showing the relatively close relationship between the Illiosentidae and the Rhadinorhynchidae. The mitochondrial gene arrangements of acanthocephalan species are relatively conserved, with only a few translocations of tRNAs (trnS1, trnS2, trnV, and trnK) detected. An identical gene order was found both in a sister clade (Centrorhynchus aluconis and Plagiorhynchus transversus) and across different classes (B. yangtzensis
