Lungworm: (Dictyocaulus arnfieldi) infection in donkeys

Veterinary Record, 1979
The clinical, parasitological and pathological findings in a group of six donkeys naturally infected with D arnfieldi larvae are described. One animal had to be sacrificed at an early date because it developed pneumonia. The remaining five were unthrifty, showed mild clinical respiratory signs and had heavy strongyle infections.

Epidemiology of Dictyocaulus viviparus in Louisiana (U.S.A.)

Veterinary Parasitology, 1989
An epidemiological investigation was conducted during a 1-year period on a permanent pasture naturally contaminated with Dictyocaulus viviparus and grazed by a varying number of yearling cattle. Seasonal variation in pasture infectivity to cattle was monitored by monthly slaughter of tracer calves, slaughter of pairs of resident yearlings at 30-60-day ...

Fog fever: Provocation tests with Dictyocaulus viviparus

Journal of Comparative Pathology, 1974
Abstract There have been many suggestions that fog fever of cattle is the result of a hypersensitivity to Dictyocaulus viviparus . However, when 7 adult cattle that had recovered from fog fever were challenged orally with 30 000 third-stage larvae of D. viviparus , the acute respiratory signs did not recur.

Radioactive Antibody Studies on Dictyocaulus filaria Infection

Research in Veterinary Science, 1971
SUMMARY Rabbit anti-sheep 7S immunoglobulins labelled with 131I were used for the estimation of immunoglobulin binding to the juvenile stage of Dictyocaulus filaria. The method showed the ability to detect the quantity of specific antibodies in sera of lambs infected with D. filaria.

The Spermatogenesis of Dictyocaulus filaria (Nematoda, Trichostrongyloidea)

The Journal of Parasitology, 1985
A cytological study was carried out, using male Dictyocaulus filaria, that revealed the diploid number of chromosomes was 2n = 11 and the sex determining mechanism was XO. The behaviour of the chromosomes in the different stages of meiosis was also investigated. Cross, open ring and rod bivalents were observed in diakinesis. The chromosomes appeared to

Local cytokine responses in Dictyocaulus viviparus infection

Veterinary Parasitology, 2005
The high degree of immunity induced by the bovine lungworm, Dictyocaulus viviparus, makes it an ideal model in which to study nematode-induced protective immune responses. Here, cytokine responses were measured over the course of an experimental infection of D. viviparus. Local cytokine messenger RNA (mRNA) transcripts were measured in lung parenchyma,

[Comparative molecular biologic characterization of Dictyocaulus viviparus and Dictyocaulus eckerti].

Berliner und Munchener tierarztliche Wochenschrift, 1996
For a comparative characterization of the lungworm species D. viviparus and D. eckerti which is not generally accepted as a separate species, the restriction fragment length polymorphism (RFLP) of the PCR amplified ribosomal second internal transcribed spacer (ITS2) and their sequences of both species have been examined.

The Effect of Dictyocaulus filaria on the Resistance of Guinea-pigs to Dictyocaulus viviparus

Research in Veterinary Science, 1967
SUMMARY Young male guinea-pigs which were given between 300 and 450 Dictyocaulus filaria infective larvae showed signs of htngworm injection 2 to 4 weeks after dosing. A further, larger dose of D. filaria larvae produced only slight symptoms of disease in these animals.

Species-specific polymerase chain reaction for the differentiation of larvae from Dictyocaulus viviparus and Dictyocaulus eckerti

Veterinary Parasitology, 1997
Using substantial interspecific differences between the second internal transcribed spacer (ITS2) region within the rDNA gene of Dictyocaulus eckerti and Dictyocaulus viviparus a species-specific PCR was developed to distinguish between lungworm larvae of the two species from fallow deer and cattle.
