| classes and crossreactivity of proteinases in the excretory-secretory products of caenorhabditis elegans. | proteinases released during the in vitro maintenance of asynchronous cultures of the free-living nematode caenorhabditis elegans were characterized on the basis of subunit composition, fluorogenic substrate specificity, inhibitor sensitivity and ph optima. cysteine proteinases are present in the excretory-secretory products (esp) as indicated by the hydrolysis of cathepsin fluorogenic substrates and confirmed by immunoblotting. serine proteinases were predominant as indicated by substrate gel an ... | 2007 | 17381874 |
| new method for simultaneous species-specific identification of equine strongyles (nematoda, strongylida) by reverse line blot hybridization. | the ability of a reverse line blot (rlb) assay to identify 13 common species of equine small strongyles (cyathostomins) and to discriminate them from three strongylus spp. (large strongyles) was demonstrated. the assay relied on the specific hybridization of pcr-amplified intergenic spacer dna fragments of the nuclear ribosomal dna to membrane-bound species-specific probes. all cyathostomins examined were unequivocally identified and simultaneously discriminated from each other and from three la ... | 2007 | 17626168 |
| a nonmineralized approach to abrasion-resistant biomaterials. | the tooth-like mouthparts of some animals consist of biomacromolecular scaffolds with few mineral components, making them intriguing paradigms of biostructural materials. in this study, the abrasion resistance of the jaws of one such animal, the bloodworm glycera dibranchiata, has been evaluated by nanoindentation, nanoscratching, and wear testing. the hardest, stiffest, and most abrasion-resistant materials are found within a thin (<3 microm) surface layer near the jaw tip and a thicker (10-20 ... | 2007 | 17702868 |
| detection and semi-quantification of strongylus vulgaris dna in equine faeces by real-time quantitative pcr. | strongylus vulgaris is an important strongyle nematode with high pathogenic potential infecting horses world-wide. several decades of intensive anthelmintic use has virtually eliminated clinical disease caused by s. vulgaris, but has also caused high levels of anthelmintic resistance in equine small strongyle (cyathostomin) nematodes. recommendations aimed at limiting the development of anthelmintic resistance by reducing treatment intensity raises a simultaneous demand for reliable and accurate ... | 2008 | 17889881 |
| effects of hydration on mechanical properties of a highly sclerotized tissue. | the jaws of the bloodworm glycera dibranchiata consist principally of protein and melanin scaffolds with small amounts of unmineralized copper (cu) and mineralized atacamite (cu(2)cl(oh)(3)) fibers in distinct regions. remarkably, when tested in air, the regions containing unmineralized cu are the hardest, stiffest, and most abrasion resistant. to establish the functions of jaw constituents in physiologically relevant environments, this study examines the effects of hydration on their response t ... | 2008 | 18192350 |

| strongylus vulgaris associated with usage of selective therapy on danish horse farms-is it reemerging? | nematodes belonging to the order strongylida are ubiquitous in grazing horses, and the large strongyle strongylus vulgaris is considered the most pathogenic. this parasite was originally described widely prevalent in equine establishments, but decades of frequent anthelmintic treatment appears to have reduced the prevalence dramatically. increasing levels of anthelmintic resistance in cyathostomin parasites have led to implementation of selective therapy to reduce further development of resistan ... | 2012 | 22703964 |
| predatory functional response and prey choice identify predation differences between native/invasive and parasitised/unparasitised crayfish. | invasive predators may change the structure of invaded communities through predation and competition with native species. in europe, the invasive signal crayfish pacifastacus leniusculus is excluding the native white clawed crayfish austropotamobius pallipes. | 2012 | 22359673 |
| association between large strongyle genera in larval cultures--using rare-event poisson regression. | decades of intensive anthelmintic treatment has caused equine large strongyles to become quite rare, while the cyathostomins have developed resistance to several drug classes. the larval culture has been associated with low to moderate negative predictive values for detecting strongylus vulgaris infection. it is unknown whether detection of other large strongyle species can be statistically associated with presence of s. vulgaris. this remains a statistical challenge because of the rare occurren ... | 2013 | 23731556 |
| hierarchical model for evaluating pyrantel efficacy against strongyle parasites in horses. | anthelmintic resistance is an increasing challenge for the control of equine parasites. the fecal egg count reduction test (fecrt) is the practical gold standard method for evaluating reduction in anthelmintic efficacy, but the interpretation is complicated due to high levels of variability. a hierarchical statistical model was described for analysis of fecrt data from multiple farms to evaluate the role of biological factors in determining the strongyle efficacy of pyrantel pamoate in a study p ... | 2013 | 23680542 |
| svsxp: a strongylus vulgaris antigen with potential for prepatent diagnosis. | strongyle parasites are ubiquitous in grazing horses. strongylus vulgaris, the most pathogenic of the large strongyles, is known for its extensive migration in the mesenteric arterial system. the lifecycle of s. vulgaris is characterised by a long prepatent period where the migrating larvae are virtually undetectable as there currently is no test available for diagnosing prepatent s. vulgaris infection. presence of s. vulgaris larvae in the arterial system causes endarteritis and thrombosis with ... | 2013 | 23557195 |
| recent advances in diagnosing pathogenic equine gastrointestinal helminths: the challenge of prepatent detection. | parasites infecting horses are ubiquitous and clinically important across the world. the major parasitic threats to equine health are cyathostomins, parascaris equorum, anoplocephala perfoliata, and strongylus vulgaris. increasing levels of anthelmintic resistance reported world wide in equine parasites have led to recommendations of constructing sustainable parasite control programmes based on systematic surveillance of parasite levels. regulations at the european union level now make anthelmin ... | 2013 | 23199789 |
| selective therapy in equine parasite control--application and limitations. | since the 1960s equine parasite control has relied heavily on frequent anthelmintic treatments often applied with frequent intervals year-round. however, increasing levels of anthelmintic resistance in cyathostomins and parascaris equorum are now forcing the equine industry to change to a more surveillance-based treatment approach to facilitate a reduction in treatment intensity. the principle of selective therapy has been implemented with success in small ruminant parasite control, and has also ... | 2014 | 24702770 |
| development of strongylus vulgaris-specific serum antibodies in naturally infected foals. | strongylus vulgaris is regarded as the most pathogenic helminth parasite infecting horses. migrating larvae cause pronounced endarteritis and thrombosis in the cranial mesenteric artery and adjacent branches, and thromboembolism can lead to ischemia and infarction of large intestinal segments. a recently developed serum elisa allows detection of s. vulgaris-specific antibodies during the six-month-long prepatent period. a population of horses has been maintained at the university of kentucky wit ... | 2014 | 24433851 |
| a polychaete's powerful punch: venom gland transcriptomics of glycera reveals a complex cocktail of toxin homologs. | glycerids are marine annelids commonly known as bloodworms. bloodworms have an eversible proboscis adorned with jaws connected to venom glands. bloodworms prey on invertebrates, and it is known that the venom glands produce compounds that can induce toxic effects in animals. yet, none of these putative toxins has been characterized on a molecular basis. here we present the transcriptomic profiles of the venom glands of three species of bloodworm, glycera dibranchiata, glycera fallax and glycera ... | 2014 | 25193302 |
| effects of daily pyrantel tartrate on strongylid population dynamics and performance parameters of young horses repeatedly infected with cyathostomins and strongylus vulgaris. | strongylid infections are ubiquitous in grazing horse populations. infections with cyathostomin (small strongyle) and strongylin (large strongyle) nematodes have long been associated with clinical disease in horses, but little is known about their subclinical impact. a masked, randomized, controlled study was conducted to evaluate the effects of daily administration of pyrantel tartrate on body condition scores, weight gain, fecal egg counts, and total worm counts of young horses repeatedly inoc ... | 2014 | 24929448 |
| physiologic and systemic acute phase inflammatory responses in young horses repeatedly infected with cyathostomins and strongylus vulgaris. | migrating strongylus vulgaris and encysted cyathostomin larvae cause a localized inflammatory response in horses. it is unknown whether these larvae elicit a systemic acute phase response (apr), evidenced by changes in serum amyloid a (saa), haptoglobin (hp), iron (fe), albumin, or albumin/globulin (a/g) ratio. in this study, 28 horses were randomly allocated to receive either pyrantel tartrate or a pelleted placebo formulation in their daily feed. concurrent with treatment, all the horses were ... | 2014 | 24529577 |

| strongyle infections and parasitic control strategies in german horses - a risk assessment. | as a consequence of the increasing levels of anthelmintic resistance in cyathostomes, new strategies for equine parasite control are being implemented. to assess the potential risks of these, the occurrence of strongyles was evaluated in a group of 1887 horses. the distribution of fecal egg counts (fecs), the frequency of anthelmintic drug use, and the deworming intervals were also analyzed. between june 2012 and may 2013, 1887 fecal samples from either selectively or strategically dewormed hors ... | 2014 | 25387542 |
| serum strongylus vulgaris-specific antibody responses to anthelmintic treatment in naturally infected horses. | strongylus vulgaris is the most pathogenic helminth parasite of horses, causing verminous endarteritis with thromboembolism and infarction. a serum enzyme-linked immunosorbent assay (elisa) has been validated for detection of antibodies to an antigen produced by migrating larvae of this parasite. the aim was to evaluate elisa responses to anthelmintic treatment in cohorts of naturally infected horses. fifteen healthy horses harboring patent s. vulgaris infections were turned out for communal gra ... | 2015 | 25358238 |
| changes in serum strongylus vulgaris-specific antibody concentrations in response to anthelmintic treatment of experimentally infected foals. | strongylus vulgaris is the most pathogenic nematode parasite of horses. its extensive migration in the mesenteric blood vessels can lead to life-threatening intestinal infarctions. recent work has shown that this parasite is still identified among managed horse populations. a serum enzyme-linked immunosorbent assay (elisa) has been developed for the detection of migrating larvae of s. vulgaris. previous work has documented an increase in elisa values following larvicidal treatment with ivermecti ... | 2015 | 26664946 |
| evaluation of baermann apparatus sedimentation time on recovery of strongylus vulgaris and s. edentatus third stage larvae from equine coprocultures. | traditional methods of diagnosing equine strongylinae infections require culturing feces, sedimenting the culture media in baermann apparatuses, collecting the sediment, and morphologically identifying recovered third stage larvae. however, this method is plagued by low negative predictive values. this study evaluated sedimentation time within the baermann apparatus by comparing larval recovery from the traditionally collected sediment, "sediment 1", and from the usually discarded remaining flui ... | 2015 | 25976635 |
| prevalence of gastrointestinal helminth parasites of equids from organized farms of mumbai and pune. | a total of 1,304 faecal samples of different species of equids were examined for presence of helminthic eggs from five different centres in mumbai and pune regions of maharashtra state from october 2011 to june 2012. overall prevalence of helminthic infestation was found to be 20.63 % with higher rate of occurrence in monsoon (31.29 %) followed by winter (20.40 %) and summer (14.23 %). four species of nematodes viz. strongyles (10.81 %), strongyloides westeri (13.19 %), parascaris equorum (0.23 ... | 2015 | 26063996 |
| new multiplex pcr method for the simultaneous diagnosis of the three known species of equine tapeworm. | although several techniques exist for the detection of equine tapeworms in serum and feces, the differential diagnosis of tapeworm infection is usually based on postmortem findings and the morphological identification of eggs in feces. in this study, a multiplex polymerase chain reaction (pcr)-based method for the simultaneuos detection of anoplocephala magna, anoplocephala perfoliata and anoplocephaloides mamillana has been developed and validated. the method simultaneously amplifies hypervaria ... | 2015 | 25498328 |
| aneurysm of the cranial mesenteric artery as a site of carriage of salmonella enterica subsp. enterica serovar abortusequi in the horse. | salmonella enterica subsp. enterica serovar abortusequi is a pathogen restricted to horses. our investigation targeted 4 draft horses (9-10 months old) kept on a japanese farm that had suffered an outbreak of s. abortusequi abortion. the 4 horses were suspected to be carriers of the bacterium owing to their high agglutination titers (≥1:2,560) in tube agglutination testing. the owners' on-farm observations confirmed that the horses had no apparent abnormalities, and s. abortusequi was not isolat ... | 2016 | 27271985 |
| effect of vacuum packing and temperature on survival and hatching of strongyle eggs in faecal samples. | strongyle eggs of helminths of livestock usually hatch within a few hours or days after deposition with faeces. this poses a problem when faecal sampling is performed in the field. as oxygen is needed for embryonic development, it is recommended to reduce air supply during transport and refrigerate. the present study therefore investigated the combined effect of vacuum packing and temperature on survival of strongyle eggs and their subsequent ability to hatch and develop into l3. fresh faecal sa ... | 2016 | 26827855 |
| fecal parasite identification by microscopy and pcr in scimitar-horned oryx, oryx dammah, managed at two sites. | the scimitar-horned oryx, oryx dammah, an endangered species extinct in the wild, is managed in various captive management programs and is the focus of reintroduction efforts. management variability can contribute to substantial parasite load differences, which can affect deworming programs and potentially transfer parasites to different regions with translocations. parasite studies in o. dammah are lacking. in this study, we determined fecal egg/oocyst counts of o. dammah in two captive herds, ... | 2016 | 27942456 |
| purification of diverse hemoglobins by metal salt precipitation. | although donated blood is the preferred material for transfusion, its limited availability and stringent storage requirements have motivated the development of blood substitutes. the giant extracellular hemoglobin (aka erythrocruorin) of the earthworm lumbricus terrestris (ltec) has shown promise as a blood substitute, but an efficient purification method for ltec must be developed to meet the potential large demand for blood substitutes. in this work, an optimized purification process that uses ... | 2016 | 26363116 |
| density-dependent prey mortality is determined by the spatial scale of predator foraging. | foraging theory predicts which prey patches predators should target. however, in most habitats, what constitutes a 'patch' and how prey density is calculated are subjective concepts and depend on the spatial scale at which the predator (or scientist) is observing. moreover, the predator's 'foraging scale' affects prey population dynamics: predators should produce directly density-dependent (ddd) prey mortality at the foraging scale, but inversely density-dependent (idd) mortality (safety-in-numb ... | 2016 | 26116266 |
| assessment of risk factors associated with prevalence of strongyle infection in equines from central plain zone, punjab. | a total of 311 equine faecal samples (190 horses and 121 mules) collected from six districts of central plain zone, punjab were examined using standard coprological methods. the results showed an overall prevalence of 27.33 % for strongyles with rare to mild type of infection as evident from egg per gram of faeces. in particular, amongst the examined samples, 17.90 % of horses and 42.14 % of mules were infected and the difference was statistically significant (p < 0.01). identification of the fa ... | 2016 | 27876953 |
