| a cross-sectional survey of gastrointestinal parasites with dispersal stages in feces from costa rican dairy calves. | a cross-sectional study was carried out to determine the prevalence of gastrointestinal parasites and lungworm nematodes in dairy calves from five different ecoclimatic areas of costa rica. also intensity of infection of nematodes was determined. in order to describe management practices and anthelmintic control, a questionnaire was applied in 73 farms. the influence of area, farm, host (breed, age) and ecological factors (low and high rainfall period) upon eggs per gram feces (epg) of gastroint ... | 2010 | 20810217 |
| synlophe patterns of the haemonchinae of ruminants (nematoda: trichostrongyloidea). | the pattern of longitudinal ridges (synlophe) on the external cuticular surface of trichostrongylid nematodes has been shown to be of value for distinguishing species and determining relationships among higher taxa. in the process of studying mecistocirrus digitatus, the large stomach worm of bovids of asia that has been imported and established in the americas, we observed remarkably similar synlophe patterns to those described for 3 species of haemonchus and to those we examined in a species o ... | 2000 | 11128486 |
| examination of gastrointestinal helminth in livestock grazing in grassland of bangladesh. | to determine association of grassland with parasitic diseases of livestock in bangladesh, the 'tracer' animals (two cow calves and two goats) were released for a month in a grassland used for communal grazing of livestock near school premise in kanthal, trishal, mymensingh, bangladesh. after slaughtering of the tracer animals, their gastrointestinal tract examination revealed six species of nematode and one cestode. the nematode species were haemonchus contortus, trichostrongylus axei, mecistoci ... | 2000 | 11002657 |
| pathophysiological aspects of mecistocirrus digitatus (nematoda: trichostrongylidae) infection in calves. | three groups of four calves were experimentally infected with infectious larvae of mecistocirrus digitatus. one group received a trickle infection of 5000 l3 per day for 8 days, the other two groups received a single infection of 5000 and 40,000 l3, respectively. all animals were necropsied 120 days after infection. prepatent periods varied between 61 and 79 days, and maximal faecal egg output was reached between 80 and 100 days after infection. repeated infections were not additive and worm cou ... | 1997 | 9195735 |
| bilateral, perivulval cuticular pores in trichostrongylid nematodes. | a new hypodermal gland was discovered in female nematodes of the family trichostrongylidae. because the new structure appears to be associated with the vulva, it was named the perivulval pore. it is similar, based on light and scanning electron microscopy, to phasmids that are located laterally on the tails of nematodes of the class secernentea. like phasmids, perivulval pores are paired and bilateral, with cuticular ducts to the surface in the areas of the lateral chords. they are located sligh ... | 1995 | 7623208 |
| pcr-based species-specific amplification of its of mecistocirrus digitatus and its application in identification of gi nematode eggs in bovine faeces. | differential diagnosis of mecistocirrus digitatus infection relies on morphological examination of either eggs in faecal samples or l3 larvae developed in vitro. technical limitations hinder the practicability of these approaches. hence, in order to develop a specific diagnostic measure for m. digitatus infection, we determined the sequence of the internal transcribed spacer (its) of its ribosomal dna (rdna) and designed primers for pcr-based species-specific amplification of the its to differen ... | 2006 | 16679725 |

| proteomic analysis of mecistocirrus digitatus and haemonchus contortus intestinal protein extracts and subsequent efficacy testing in a vaccine trial. | gastrointestinal nematode infections, such as haemonchus contortus and mecistocirrus digitatus, are ranked in the top twenty diseases affecting small-holder farmers' livestock, yet research into m. digitatus, which infects cattle and buffalo in asia is limited. intestine-derived native protein vaccines are effective against haemonchus, yet the protective efficacy of intestine-derived m. digitatus proteins has yet to be determined. | 2014 | 24901227 |
| relative importance of larval and adult mecistocirrus digitatus in inducing resistance to a reinfection in calves. | calves immunized with adult mecistocirrus digitatus implanted directly into the abomasum did not develop a substantial degree of immunity to a subsequent large oral (challenge) dose of larvae, which developed to maturity. in contrast animals immunized by oral infection developed strong resistance. the calves implanted with adult worms appeared to show a greater degree of susceptibility to maturation of the challenge infection than controls which received a challenge of the same magnitude without ... | 1987 | 3105161 |
