Systemic infection with Alaria americana (Trematoda). (1/297)

Alaria americana is a trematode, the adult of which is found in mammalian carnivores. The first case of disseminated human infection by the mesocercarial stage of this worm occurred in a 24-year-old man. The infection possibly was acquired by the eating of inadequately cooked frogs, which are intermediate hosts of the worm. The diagnosis was made during life by lung biopsy and confirmed at autopsy. The mesocercariae were present in the stomach wall, lymph nodes, liver, myocardium, pancreas and surrounding adipose tissue, spleen, kidney, lungs, brain and spinal cord. There was no host reaction to the parasites. Granulomas were present in the stomach wall, lymph nodes and liver, but the worms were not identified in them. Hypersensitivity vasculitis and a bleeding diathesis due to disseminated intravascular coagulation and a circulating anticoagulant caused his death 8 days after the onset of his illness.  (+info)

Functional differentiation in trematode hemoglobin isoforms. (2/297)

The Hbs and the major electrophoretic Hb components (isoHbs) were isolated from three species of the trematodes, Explanatum explanatum (Ee), Gastrothylax crumenifer (Gc) and Paramphistomum epiclitum (Pe), that parasitise the common Indian water buffalo Bubalus bubalis. The Hbs are monomeric and resemble the so-called nonfunctional mutant hemoglobins that have Tyr at B10 or E7 positions (replacing Leu and the His residues, respectively). However, they are capable of binding with O2 and CO. O2 equilibrium studies of trematode Hb isoforms reveal extremely high O2 affinities, with half-saturation O2 tension (P50) values up to 800 times lower than those of human hemoglobins. This correlates with Tyr residues at B10 and at the distal position (E7) that decrease the O2 dissociation rate by contributing hydrogen bonds (H-bonds) to the bound O2. These substitutions also increase the O2 association rates either due to orientation of E7-Tyr towards the solvent and/or by sterically hindering the entry of water molecules into the heme pocket. The latter may account for the low rate of autoxidation of trematode Hbs. The Hbs and their isoforms from different species exhibited pronounced variation in O2 affinity, which may relate to subtle differences in the structure of the heme pocket. The O2 affinities of the composite (unfractionated) Hbs were intermediate to those of the individual Hb isoform. The P50 values of Hbs here obtained by direct O2 equilibrium measurements differed from those calculated from kinetic data already published [Kiger, L., Rashid, A. K., Griffon, N., Haque, M., Moens, L.,Gibson, Q. H., Poyart, C., & Marden, M. C. (1998). Biophys. J. 75, 990-998.] Intermediate state(s) due to slow reorientation of E7-Tyr may account for this difference. Some Hb isoforms showed slight (either normal or reverse) Bohr effects. The hyperbolic O2 equilibrium curve, Hill coefficient (n) values near unity accord with a monomeric nature of trematode Hbs. In marked contrast to vertebrate Hbs, CO does not seem to compete effectively with O2 in trematode Hbs, as evident from partition coefficient values (M) below 1.  (+info)

Growth and development of Gymnophalloides seoi in immunocompetent and immunosuppressed C3H/HeN mice. (3/297)

The growth and development of Gymnophalloides seoi were studied in C3H/HeN mice and effects of immunosuppression of the host on the worm development were observed. Two hundred metacercariae of G. seoi were orally administered to each mouse, and worms were recovered on days 1, 3, 5, 7, 14 and 21 post-infection (PI). The worm recovery rate was significantly higher in immunosuppressed (ImSP) mice than in immunocompetent (ImCT) mice except on days 1 and 3 PI. The worms attained sexual maturity by day 3 PI with eggs in the uterus, and worm dimensions and the number of uterine eggs continuously increased until day 14 PI in ImSP mice. Worms recovered from ImSP mice were significantly larger in size than those from ImCT mice on days 1 and 3 PI, and the number of uterine eggs was significantly larger in ImSP mice on days 5 and 7 PI. Genital organs such as the ovary, testes, and vitellaria, that were already developed in the metacercarial stage, grew a little in size until day 14 PI. The results show that the C3H/HeN mouse is, though not excellent, a suitable laboratory host for G. seoi.  (+info)

A 54 kDa cysteine protease purified from the crude extract of Neodiplostomum seoulense adult worms. (4/297)

As a preliminary study for the explanation of pathobiology of Neodiplostomum seoulense infection, a 54 kDa protease was purified from the crude extract of adult worms by sequential chromatographic methods. The crude extract was subjected to DEAE-Sepharose Fast Flow column, and protein was eluted using 25 mM Tris-HCl (pH 7.4) containing 0.05, 0.1, 0.2 and 0.4 M NaCl in stepwise elution. The 0.2 M NaCl fraction was further purified by Q-Sepharose chromatography and protein was eluted using 20 mM sodium acetate (pH 6.4) containing 0.05, 0.1, 0.2 and 0.3 M NaCl, respectively. The 0.1M NaCl fraction showed a single protein band on SDS-PAGE carried out on a 7.5-15% gradient gel. The proteolytic activities of the purified enzyme were specifically inhibited by L-trans-epoxy-succinylleucylamide (4-guanidino) butane (E-64) and iodoacetic acid. The enzyme, cysteine protease, showed the maximum proteolytic activity at pH 6.0 in 0.1 M buffer, and degraded extracellular matrix proteins such as collagen and fibronectin with different activities. It is suggested that the cysteine protease may play a role in the nutrient uptake of N. seoulense from the host intestine.  (+info)

The effect of trematode infection on amphibian limb development and survivorship. (5/297)

The causes of amphibian deformities and their role in widespread amphibian declines remain conjectural. Severe limb abnormalities were induced at high frequencies in Pacific treefrogs (Hyla regilla) exposed to cercariae of a trematode parasite (Ribeiroia sp.). The abnormalities closely matched those observed at field sites, and an increase in parasite density caused an increase in abnormality frequency and a decline in tadpole survivorship. These findings call for further investigation of parasite infection as a cause of amphibian deformities in other sites and species.  (+info)

Infection status of dragonflies with Plagiorchis muris metacercariae in Korea. (6/297)

Plagiorchis muris has been found in both house and field rats as well as in humans. The infection status of the second intermediate hosts of P. muris is prerequisite in understanding their biological features in an ecosystem. Six species of dragonflies were caught in a wide range of areas in Korea; and they were Sympetrum darwinianum, S. eroticum, S. pedomontanum, S. infuscatum, Pantala flavoscens, Calopteryx atrata, and Orthetrum albistylum speciosum. The occurrence of P. muris metacercariae in dragonflies was nationwide with various infection rates. The metacercarial burden of P. muris in the surveyed areas was the highest in S. eroticum followed by S. darwinianum, S. pedomontanum, and C. atrata. The highest infection rate by P. muris metacercariae was found in S. darwinianum followed by S. eroticum. The metacercarial burden was particularly heavy in the dragonflies found in Hamyang-gun and Kosong-gun, Kyongsangnam-do. It is, therefore, likely that dragonflies play a significant role as the second intermediate host in the life cycle of P. muris in Korea.  (+info)

Distribution patterns of marine bird digenean larvae in periwinkles along the southern coast of the Barents Sea. (7/297)

An important component of the parasite fauna of seabirds in arctic regions are the flukes (Digena). Different species of digeneans have life cycles which may consist of 1 intermediate host and no free-living larval stages, 2 intermediate hosts and 1 free-living stage, or 2 intermediate hosts and 2 free-living larval stages. This study examined the distribution of such parasites in the intertidal zones of the southern coast of the Barents Sea (northwestern Russia and northern Norway) by investigating 2 species of periwinkles (Littorina saxatilis and L. obtusata) which are intermediate hosts of many species of digeneans. A total of 26,020 snails from 134 sampling stations were collected. The study area was divided into 5 regions, and the number of species, frequency of occurrence and prevalence of different digenean species and groups of species (depending on life cycle complexity) were compared among these regions, statistically controlling for environmental exposure. We found 14 species of digeneans, of which 13 have marine birds as final hosts. The number of species per sampling station increased westwards, and was higher on the Norwegian coast than on the Russian coast. The frequency of occurrence of digeneans with more than 1 intermediate host increased westwards, making up a larger proportion of the digeneans among infected snails. This was significant in L. saxatilis. The prevalence of different species showed the same pattern, and significantly more snails of both species were infected with digeneans with complicated life cycles in the western regions. In L. saxatilis, environmental exposure had a statistically significant effect on the distribution of the most common digenean species. This was less obvious in L. obtusata. The causes of changing species composition between regions are probably (1) the harsh climate in the eastern part of the study area reducing the probability of successful transmission of digeneans with complicated life cycles, and (2) the distribution of different final hosts.  (+info)

Helminth fauna of carnivores distributed in north-western Tohoku, Japan, with special reference to Mesocestoides paucitesticulus and Brachylaima tokudai. (8/297)

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)

Abstract Gymnophalloides seoi (Digenea: Gymnophallidae), a new human intestinal trematode reported from a Korean woman who complained of epigastric discomfort, has been shown to be highly prevalent among the villagers of a southwestern island of the Republic of Korea. For the detection of human infections, fecal examinations were conducted on the inhabitants of a seashore village, where the first patient with a G. seoi infection had resided. Of 98 inhabitants examined, 70 (71.4%) were infected with various intestinal parasites; among them, G. seoi showed the highest rate of egg positivity 48 of 98 (49.0%). Individual worm burdens of G. seoi, as measured by collection of adult flukes after anthelmintic treatment and purgation, ranged from 106 to 26,373 specimens (average per infected case = 3,326). There was no sex-related difference in the prevalence of G. seoi, and the age distribution of the infected cases showed a relatively even pattern. This study confirms that human infection by G. seoi is not an
Nearly every species on the planet has at least one parasite, which, by definition, incurs a cost in the host. Therefore, organisms must resist parasites - preventing or reducing infections - or tolerate parasites - reducing the costs of infection - in order to maintain their fitness despite the presence of parasites. Here, I investigated: 1) whether parasitic, larval trematodes (cercariae) can detect the least resistant tadpole host species, 2) a hypothetical framework for how host life history impacts the utilization of inflammation and thus, resistance and tolerance, 3) whether a common anesthesia technique used in experimental infections immunocompromises tadpoles, 4) the relationship between tadpole host life history, tolerance, and behavioral resistance to cercarial infection, 5) how tadpole behavior affects trematode infection location, and 6) how host life history impacts trematode infection location and the implications of this for host tolerance. In the first chapter, I investigated whether

Microphallus piriformes is a parasitic trematode (fluke). It belongs to the Plagiorchiata, a large suborder of the digenean fluke order Plagiorchiida. M. piriformes is unusual among the flukes in having only one intermediate host rather than two, and no free-swimming cercarian stage. It is most notable, however, for modifying the behaviour of its intermediate host in a way that increases its chance of transmission to the primary host. This has been researched by Helen O. McCarthy and her team of University of Ulster scientists both in the laboratory and at Muck Island in Scotland. The life cycle of M. piriformes requires two hosts: the rough periwinkle Littorina saxatilis (a littoral snail) and the herring gull Larus argentatus (and perhaps other members of the herring gull complex). The immature flukes live in the snail, and the adult flukes live in the bird. Normally, rough periwinkles are rarely eaten by herring gulls. This is due to two reasons: First, the birds forage in the snails rocky ...

Clinostomum marginatum is a species of parasitic flukes (class Trematoda). It is commonly called the yellow grub. It is found in many freshwater fish in North America, and no fish, so far is immune to this parasite. This type of fluke can be found in the mouth of aquatic birds such as herons and egrets. They are also found commonly in the esophagus of fish-eating birds, and reptiles. Eggs of these trematodes are shed in the feces, hopefully into the water. Many aquatic birds become infected by ingesting freshwater fish that are infected. The metacercariae are found right beneath the skin or in the muscles. Life cycle of this yellow grub consists of two intermediate hosts and one definitive host. The parasites eggs hatch in the water and the miracidium invades the foot of the snails. The cercaria leaves the snail and encysts in the muscle of the connective tissue of fresh-water species. The metacercarial stage is that is formed is then referred to as the yellow grub. The encysted ...
A high prevalence of vertebral deformities has been observed in various fishes, especially cyprinids, from certain regions of the Willamette River for many years. One proposed source of these deformities is exposure to toxicants. Histological evaluation of affected chiselmouth Acrocheilus alutaceus revealed that all lesions associated with vertebrae were associated with metacercariae of digenean trematodes. Approximately half of the northern pikeminnow Ptychocheilus oregonensis had infections in which metacercariae were associated with these lesions. Metacercariae were also associated with vertebral lesions in three of four affected peamouth Mylocheilus caurinus. Many metacercariae that were present within the vertebral bodies were associated with bony dysplasia and bony proliferation in all three species. We also evaluated the association of the metacercariae with the vertebral deformities, using intact fish that had been cleared with trypsin. Fish from the affected regions had a much higher ...

Microphallus, or micropenis, is defined as a stretched penile length of less than 2.5 standard deviations (SDs) below the mean for age.
While A. contortum seems to do quite well in its rather unusual (for a trematode) habitat, the basic body plan for trematode is that of an internal parasite. So how does one modify a body plan for living inside the cosy confine of a hosts body to a life clinging on to the more exposed parts of the host? Fortunately for A. contortum there are some functional overlaps between living in a fishs intestine versus living on its gills. While it lacks the hooks and sucker clamps of monogenean flatworms which are specialised for ectoparasitism, A. contortum has co-opted its large and muscular ventral sucker for hanging on to the sunfishs gills. Other trematode species use their ventral sucker to attach to the intestinal wall. In A. contortum it also function as the main attachment organ, but on a different part of the hosts body. Additionally, this flukes hind body appears to be long and prehensile, which it might to able to use to grip like a chameleons tail (to a limited degree ...
We identified 7584 pairs of one-to-one orthologous transcripts between the two transcriptomes (see Table S2) and 7851 and 21,980 nonone-to-one orthologous transcripts for PA-Microphallus and PE-Microphallus, respectively. The two one-to-one ortholog transcriptomes contain higher mean transcript lengths (18.6% longer for PA-Microphallus; 38.7% longer for PE-Microphallus) and larger N50 values (11.7% greater N50 for PA-Microphallus; 33.9% greater N50 for PE-Microphallus) than their corresponding reference transcriptomes (Table 1). The longer transcripts and higher N50 values in the one-to-one ortholog sets relative to the reference transcriptomes indicate that the one-to-one orthologs represent a set of approximately full-length high quality genes that occur once and only once in both transcriptome assemblies. More than half (PA-Microphallus: 51.7%; PE-Microphallus: 51.2%) of the BUSCO genes are retained in this reduced gene set, further indicating that our filtering steps likely removed poor ...
The purpose of this thesis is to obtain an understanding of parasite ecology and the incidence of black spot disease in freshwater fish. Parasite morphology, transmission, and life cycles are important to understand before being able to control a parasite. Uvulifer ambloplitis is a larval trematode worm that infects freshwater fish and causes a black pigment to be produced in response to its metacercariae stage. Other immune responses and effects on the intermediate hosts, fish and snails, are examined. A study was done on the fish of Rutledge Creek, Virginia to take a closer look at the epidemiology of this parasite. A flourishing parasite community at Rutledge Creek can be an indicator of good stream health and quality. Typically, the prevention and control of trematode parasites focuses on molluscicidal chemicals and plants.

Heres Lepidapedon, a lepocreadiid digenean. Lepocreadiids are very common in marine fishes and are almost a prototypical digenean; they have oral and ventral suckers, two testes (the big medial blue blobs), one ovary (darker blue blob in front), a lot of cortical vitelline follicles for making egg shells (the brown blobs all round the outside) and a lightly spiny tegument, which probably aids them in holding onto the intestinal mucosa of their teleost fish hosts. Like all digeneans, they have complex life cycles involving a mollusk first intermediate host, but in most cases, including this one, that host is not known. After the mollusk comes a crustacean of some sort, again unknown in this case, which is actively penetrated by the cercarial stage that emerges from the mollusk. The definitive fish host becomes infected by eating the crustacean. This Lepidapedon is from the intestine of the butterfish, Peprilus triacanthus, a common midwater schooling fish on the Atlantic coast ...

My research interests are in the broad area of parasite ecology. Ecology is the study of interactions of organisms with each other and with their environment. A parasites lives on, or in, a living host during some part of its life. A host, therefore, is both another organism and the parasites environment. Consequently, there are many fascinating ecological questions to be addressed surrounding host-parasite relationships. Both hosts and parasites vary widely in their biological characteristics. Some parasites have complex life cycles involving multiple hosts while others have direct life cycles. In any case, one of the main challenges to success as a parasite is successful transmission of offspring into new hosts. I am interested in how various aspects of host and parasite biology, as well as environmental factors, interact to structure parasite assemblages in host individuals, populations, and communities. This has led me to work with communities of larval trematodes in freshwater snails and ...

More common in relatively deep (1-2 m), still water. Very common in freshwater plains (Ref. 4515, 57235). Occur in medium to large rivers, brooks, flooded fields and stagnant waters including sluggish flowing canals (Ref. 12975). Survive dry season by burrowing in bottom mud of lakes, canals and swamps as long as skin and air-breathing apparatus remain moist (Ref. 2686) and subsists on the stored fat (Ref. 1479). Feed on fish, frogs, snakes, insects, earthworms, tadpoles (Ref. 1479) and crustaceans (Ref. 2847). Undertake lateral migration from the Mekong mainstream, or other permanent water bodies, to flooded areas during the flood season and return to the permanent water bodies at the onset of the dry season (Ref. 37770). During winter and dry season, its flesh around coelomic cavity is heavily infested by a larval trematode ...

My research revolves around trying to answer this question: How can fundamental studies of developmental biology & gene regulation guide our search for next generation anthelmintic solutions?. Parasitic worms cause some of the most disfiguring, debilitating & chronic infectious diseases of human & animal populations across the globe. Reliance on limited drug classes to treat affected individuals & the lack of available vaccines to induce protective immunity suggests that current experimental approaches in identifying urgently needed anthelmintics have yet to deliver sustainable solutions.. Utilising both hypothesis-led & discovery driven research approaches my laboratory is developing new strategies for controlling parasitic helminths of biomedical importance. Our area of expertise is Schistosoma mansoni, one of the three main trematode species responsible for the neglected tropical disease Schistosomiasis. More than 200 million people suffer from this chronic & debilitating disease, with 90% of ...
A phenomenon of switching of the parasite in the food chain to an accidental host is commonly observed in nature. However, there is little available data concerning the morphological descriptions of parasites that passively get into the atypical hosts and are capable, at least to some degree, of somatic growth and development of reproductive structures. A morphological survey of Diplodiscus subclavatus (Pallas, 1760) adults isolated from a digestive tract of an accidental host, Viviparus contectus (Millet, 1813), was carried out. Diplodiscus subclavatus individuals identified in prosobranch snails were morphologically similar to adult forms of the parasite described from amphibians, typical final hosts in the life cycle of this paramphistomid. The observed forms of D. subclavatus had a fully developed reproductive system, sperm in the seminal vesicle and oocytes in the ovary. The number of eggs in the uterus ranged from 3 to 17. Our research indicates that D. subclavatus individuals reach the ...
When subjected to molecular examine, species of digeneans believed to be cosmopolitan are often discovered to encompass complexes of species with narrower distributions. We current molecular and morphological proof of transcontinental distributions in two species of Apharyngostrigea Ciurea, 1924, based mostly on samples from Africa and the Americas. Sequences of cytochrome c oxidase I (CO1) and, in some samples, inside transcribed spacer (ITS), revealed Apharyngostrigea pipientis (Faust, 1918) in Tanzania (first recognized African document), Argentina, Brazil, USA and Canada. Sequences from A. pipientis additionally match beforehand revealed sequences recognized as Apharyngostrigea cornu (Zeder, 1800) originating in Mexico.. Hosts of A. pipientis surveyed embody definitive hosts from the Afrotropic, Neotropic and Nearctic, in addition to first and second intermediate hosts from the Americas, together with the kind host and sort area. As well as, metacercariae of A. pipientis had been obtained ...

Larva alebo larválne štádium je nedospelé vývinové štádium živočíchov, ktoré sa buď postupným zvliekaním (nedokonalá premena) alebo prostredníctvom kukly (dokonalá premena) zmení na dospelého jedinca. Na rozdiel od mláďat sú larvy často anatomicky a morfologicky značne odlišné od dospelých jedincov. U hmyzu s dokonalou premenou nemá vonkajšie znaky imága (napr. u motýľa ide o húsenicu). Posledný instar larvy sa premieňa na kuklu. Larválne štádium je súčasťou postembryonálneho vývinu jedinca. Larvy vznikajú ako výsledok pohlavného rozmnožovania, zriedkavú výnimku tvoria brvoústovce (Cycliophora), z ktorých sa nepohlavným pučaním vytvára larva pandora. Samotné larvy pohlavného rozmnožovania nie sú schopné. Niektoré larvy sa však dokážu rozmnožovať nepohlavne. Túto vlastnosť majú larvy niektorých parazitov napríklad motolíc (Trematoda). Umožňuje im tak vytvoriť obrovské množstvo infekčných štádií, čo je nevyhnutné, ...
Worldwide, >18 million persons were infected with fish-borne zoonotic trematodes in 2002. To evaluate the effectiveness of interventions for reducing prevalence and intensity of fish-borne zoonotic trematode infections in juvenile fish, we compared transmission rates at nurseries in the Red River Delta, northern Vietnam. Rates were significantly lower for nurseries that reduced snail populations and trematode egg contamination in ponds than for nurseries that did not. These interventions can be used in the development of programs for sustained control of zoonotic trematodes in farmed fish.

Fish-borne zoonotic trematodes (FZT), such as Clonorchis sinensis, Opistorchis viverini (Opisthorchiidae) and intestinal trematodes of the family Heterophyidae, constitute a public health hazard in Vietnam and infections with these trematodes has been linked to consumption of raw or undercooked fish from aquaculture. The FZT transmission pathways, however, are more complicated than just the presence of intermediate snail hosts in aquaculture ponds as ponds may exchange water with surrounding habitats such as rice fields and irrigation canals and thereby these surrounding habitats may be a source of snails and cercariae and contribute to FZT infection in cultured fish. This is a longitudinal descriptive study on selected farms (n = 30) in Nam Dinh Province which is endemic for FZT. At each farm, we sampled one pond, a small irrigation canal used to supply the pond with water, and a nearby rice field. At each of these three sites, we estimated the density of the FZT intermediate snail hosts and determined

This review examines the literature on imported (allochthonous) and local (autochthonous) cases of food-borne trematode (FBT) infections in the United States of America (USA) from 1890 to 2009. Most of the literature is concerned with imported cases of the opisthorchiids Clonorchis sinensis and Opisthorchis viverrini. These flukes cause serious pathology in the liver and biliary system of humans. Chronic cases may induce liver (hepatocarcinoma) and bile duct (cholangiocarcinoma) cancers in humans. Clonorchiasis and opithorchiasis are preventable diseases that can be avoided by eating properly cooked freshwater fish products. Several species of lung flukes in the genus Paragonimus are local or imported FBT in the USA. The endemic cycle occurs in the USA with various local snails and crustaceans serving as intermediate hosts. Paragonimids are acquired when humans eat raw or improperly cooked freshwater crustaceans containing metacercarial cysts. Infection can cause severe lung disease and the ...

Foodborne trematodiasis is an emerging public health problem, particularly in Southeast Asia and the Western Pacific region. We summarize the complex life cycle of foodborne trematodes and discuss its contextual determinants. Currently, 601.0, 293.8, 91.1, and 79.8 million people are at risk for infection with Clonorchis sinensis, Paragonimus spp., Fasciola spp., and Opisthorchis spp., respectively. The relationship between diseases caused by trematodes and proximity of human habitation to suitable freshwater bodies is examined. Residents living near freshwater bodies have a 2.15-fold higher risk (95% confidence interval 1.38-3.36) for infections than persons living farther from the water. Exponential growth of aquaculture may be the most important risk factor for the emergence of foodborne trematodiasis. This is supported by reviewing aquaculture development in countries endemic for foodborne trematodiasis over the past 10-50 years. Future and sustainable control of foodborne trematodiasis is discussed
ABSTRACT: The digenean trematode Proctoeces maculatus is an important parasite of the blue mussel Mytilus edulis. The parasite reduces mussel quality and yield, negatively impacting mussel aquaculture efforts. Typically, the trematode is detected by visual observation. To provide a better diagnostic tool able to detect this parasite at any life stage and at low intensities, we designed a species-specific molecular assay to detect P. maculatus in M. edulis tissue. Primers targeting the 18S nuclear ribosomal DNA (rDNA) from P. maculatus were used to develop an end-point polymerase chain reaction assay and a quantitative polymerase chain reaction (qPCR) assay. Analytical specificity of the assays was demonstrated using DNA from 4 other digenean trematodes. The qPCR assay was linear from 6.79 × 102 to 6.79 × 107 copies of the cloned target DNA and had a conservative detection limit of 68 copies. The qPCR assay detected single cercariae, and the number of isolated cercariae was linearly correlated ...

ABSTRACT. This study was carried out to establish whether cattle can develop resistance to re-infection by Calicophoron microbothrium by assessing the response of intestinal mucosal globule leukocytes, eosinophils, mast cells and basophils, and the establishment of the parasite in the host. A total of 24 1-year-old Tuli steers were randomly divided into four groups of six animals each and infected with C. microbothrium metacercariae. On the first day of the study, animals in Groups I and II were immunized with 5 000 metacercariae and then challenged with 15 000 metacercariae on Day 150 post-immunization. Animals in Group III were immunized with 15 000 metacercariae at the same time that Groups I and II animals were challenged to act as a positive control group. Animals in Group IV were left uninfected and acted as a negative control group. Three animals from each group were slaughtered on Day 28 post-challenge and the remainder were slaughtered on Day 42 post-challenge. The established ...

The role of antagonistic organismal interactions in the production of long-term macroevolutionary trends has been debated for decades. Some evidence seems to suggest that temporal trends in predation frequency share a common causative mechanism with genus-level diversity, whereas studies on the role of parasites in shaping the evolutionary process are rare indeed. Digenean trematodes (Phylum Platyhelminthes) infest molluscs in at least one stage of their complex life cycle. Trematodes leave characteristic oval-shaped pits with raised rims on the interior of their bivalve hosts, and these pits are preserved in the fossil record. Here we survey 11,785 valves from the Pleistocene-Holocene deposits of the Po Plain and from nearby modern coastal environments on the northeast Adriatic coast of Italy. Of these, 205 valves exhibited trematode-induced pits. Trematodes were selective parasites in terms of host taxonomy and host body size. Infestation was restricted to lower ...

A cross sectional study was carried out from October 2010 to April 2011 in Gondar Elfora Abattoir to determine the prevalence of paramphistomosis in cattle (local, cross) breeds which were came from highland, mid highland and lowland areas. Three hundred eighty-four (384) cattle were included for routine ante-mortem and postmortem examination for the presence of paramphistomum. The parasite was examined grossly and under microscope to appreciate the morphology of adult paramphistomum. Out of 384 cattle examined, 199 (51.82%) were found to be positive for paramphistomosis. From 199 infected cattle fluke burden at organ level 125(62.81%) was in rumen, 40(20.1%) was in reticulum and 34(17.09%) was found mixed (rumen and reticulum). The existence of paraphistomum in respect to organ and origin, 56(44.80%) was in rumen and 20(50%) was found in reticulum predominantly in high and low land respectively. The highest infection of cattle with paramphistomum species was found during October to November. However

In this study, specificity of snail feet and hepatopancreases antigens in antibody detection of their trematode parasite was evaluated via Western blot technique. Snails, of two different families, antigens; Lymnaea cailliaudi as intermediate host of Fasciola gigantica and Biomphalaria alexandrina as intermediate host of Paramphistomum microbothrium, were evaluated in detection of IgG antibodies against their trematode parasites after preparation of the required Hyper-Immune Sera (HIS) in rabbits. The results revealed higher specificity of snail feet in antibody detection than hepatopancreases antigens. Where, three of sex polypeptides of L. cailliaudi feet antigen; identified by F. gigantica HIS, showed specific positive reactivity. These polypeptides were at molecular weights of 59, 57 and 52 kDa. While, one of sex polypeptides of L. cailliaudi hepatopancreases antigen; identified by F. gigantica HIS, at molecular weight of 57 kDa was specific. Similarly, two polypeptides of B. alexandrina ...

Well, we couldnt have any of that nasty adaptive evolution happening could we? Except of course that Schistosomes and Fasciola are but two representatives of trematoda, a large class of parasitic worms that include a two host cycle, with one stage usually occurring in molluscs, the second usually in vertebrates. The cercaria is common to all the trematodes. As well as the liver flukes, there are the lung Flukes (Paragonimidae) and the intestinal Flukes (Fascicoliposis). These are just the ones of disease importance to humans. Then there is Bivesiculidae, the Transversotremidae, the Lepocreadidae and on and on. Indeed there are over 180 families of trematodes which have the life cycle and larval stages (including cercaria) associated with Schistosomes. Indeed, the Schistosomes considered by Wood et al are just one genus in the family Schistosomatidae, venous system specialists that infect reptiles, birds and mammals (including humans). Then there is the family of Spirochidae, blood vessel ...

Poverty has been established as the driver for many diseases, both infectious and non-infectious. The major focus of research in prevention and management has taken a single disease focus. The increasing occurrence of multiple infections and diseases, however, cannot be ignored. Co-infection is the simultaneous infection of a host by multiple pathogen species, for instance multi-parasite infections. Co-infection also occurs as simultaneous infection of a single cell by two or more virus particles, which can arise incrementally by initial infection followed by superinfection. Co-infection is of particular human health importance because pathogen species can interact within the host. Interactions within the host can have either positive or negative effects on each of the co-infecting parasite species. Under positive parasite interactions, disease transmission and progression are enhanced. Syndemics refers to the aggregation of two or more diseases or afflictions in a population where there is a ...

Extending community assembly theory to communities of co-infecting parasites, we used a gastrointestinal nematode removal experiment in free-ranging African buffalo to examine community assembly patterns and processes. 2.We first asked whether reassembled communities differ from undisturbed communities by comparing anthelmintic-treated and control hosts. Next, we examined the temporal dynamics of assembly using a cross-section of communities that reassembled for different ...

Within this broad description we can find a wealth of detail; I reviewed much of that detail in a 2002 book (Moore, 2002), and will describe a fraction of it here. When we think of manipulative parasites, the challenge of getting to the host occupies much of our attention, although enhancing parasite survival and reproduction does not lag far behind. Indeed, what seems to be the earliest suggestion of parasite manipulation of a host was tied to possible trophic consequences. I hesitate to call this suggestion one about transmission, because in 1853, when Siebold [cited in Kagan (Kagan, 1951); see also Ahrens (1810), cited in Lewis (Lewis, 1977)] wondered whether the pulsating tentacles of snails infected with Leucochloridium might attract predators, the first trematode life cycle had yet to be discovered. Of course, Leucochloridium in snails is highly visible - the snails are said to crawl out into lighted areas, and the striped broodsacs pulsate; this visibility is something to keep in mind as ...

Compared with the history of research on the range of health effects of DES daughters, there are relatively few published medical research studies conducted with DES sons. And yet, the finding that prenatal DES exposure also led to detrimental effects for a number of exposed males has existed since the 1970s (Andonian and Kessler, 1979; Bibbo et al., 1977; Gill et al., 1979; Gill, et al., 1988; Laitman et al., 1997). These effects include a variety of structural abnormalities of the reproductive system such as epididymal (benign) cysts, hypoplastic testes or undescended testes (chryptorchidism), microphallus or underdeveloped penis which may be associated with an intersex condition, and hypospadias (opening of the penis is on the underside rather than at the end).

First lay the fish in your hand with its head toward your palm and the tail toward your fingers. Hold the dorsal spine between your middle and ring finger so the fish is belly up and you wont get punctured by the sharp fin spines (which hurts - be careful). The genital pore is in a small furrow of tissue (in healthy fish) and will be obstructed by the pelvic fins. Pull down on the tail gently to arch the fishes spine and the pelvic fins will stand and the furrow open to display the genital pore and the anus of the fish. The male has a somewhat ridged genital papillae on which the spermatoduct is on the back side, facing the tail fin. A gravid female will also show an extended papillae but the oviduct is on the ventral side of the papillae. It may also show a little redness if really gravid. A thin or emaciated female will have just two pink pores, the oviduct and the anus ...
Found in free swimming parasitic copepods captured in plankton nets. Transfers from one copepod host to another when these crustacean parasites are mating (a sexual disease of copepods). May feed on parasitic copepods instead of fish host; covers these crustacean parasites with eggs that are probably detrimental. May harm other parasites and may actually benefit fish host (Ref. 359). Members of the class Trematoda are parasitic, thus requires a host to survive. Life cycle: Eggs are passed on to the feces of the hosts. Embryos hatch into miracidia and penetrate the tissues of snails where they further undergo three stages: sporocysts (Ref. 833). ...
