Dictyocaulus Filaria and Muellerius capillaris are Important Lungworm Parasites of Sheep in Wogera District, Northern Ethiopia
2020Co-Authors: Nibret Moges, Basaznew Bogale, Mersha ChanieAbstract:Cross-sectional study was conducted from October 2010 to March 2011 to determine lungworm species and their prevalence in sheep and evaluate the effect of risk factors in Wogera district, northern Ethiopia. Faecal samples were randomly taken from 390 heads of sheep for examination of first stage larvae (L1) of lungworms using a modified Baerman technique. The overall prevalence of lungworm infection was in sheep 67.69% (264 of 390). The lungworm species found were Dictyocaulus Filaria (D. Filaria) and Muellerius capillaris (M. capillaris) as single and mixed infection. The proportions of infection by D. Filaria, M. capillaris and mixed were 55.30, 25.75 and 18.93%, respectively. Sex-wise infection rate was 69.78 and 68.15% in males and females, respectively with no significant difference (p>0.05) among them. The infection rate of D. Filaria and M. capillaris infection could not show significant difference (p

Likewise, the infection rate between male and female animals did not show significant difference (p<0.05). This study showed high prevalence of lungworm infection which impairs the productivity of small ruminants, implying the need for control intervention.

parasitic bronchitis in goats and the possible use of Dictyocaulus Filaria vaccine for its control
Veterinary Parasitology, 1994Co-Authors: Rinku SharmaAbstract:Abstract Parasitic bronchitis is widely prevalent in migratory flocks of small ruminants in the northwest Himalayan regions of India. The prevalence data collected from 5554 goats, maintained in 31 villages in different agroclimatic regions of the Himalayas, showed that the prevalence of the disease in goats varied from 18.7 to 47.6% with an overall prevalence of 21.8%. Interestingly, 27.6% of goats maintained at an altitude of 2700–3900 m above mean sea level in Kargil (Jammu and Kashmir), where the climate is cold and dry for the major part of the year, were positive for the lungworm infections. The common lungworms observed were Dictyocaulus Filaria, Protostrongylus rufescens, Varestrongylus pneumonicus and occasionally Muellerius spp. The kids were more susceptible to lungworm infections than adult goats. In experimental studies, it was seen that goats were more susceptible to Dictyocaulus Filaria infection than sheep and two vaccine doses comprising 1000 and 2000 gamma-attenuated D. Filaria (ovine strain) infective larvae conferred 97% protection in male Beetal kids against a homologous challenge dose of 4200 normal D. Filaria larvae. The importance of simultaneous control of the disease in goats and sheep is discussed.

effect of bronchodilator and intravascular oxygen releaser on the course of Dictyocaulus Filaria infection in lambs
Veterinary Parasitology, 1990Co-Authors: Rinku Sharma, T. K. BhatAbstract:Abstract The effect of a bronchodilator (or ciprenaline sulphate) and intravascular oxygen releaser (sodium dihydrogen orthophosphate) on the host in experimental Dictyocaulus Filaria infection was studied. Fifteen male lambs of Dorset-Muzaffarnagri breed, aged 4–6 months, were divided into four groups of four (infected bronchodilator), four (infected I.V. O2 releaser), four (infected untreated controls) and three (uninfected controls). The administration of I.V. O2 releaser helped in increasing the length of useful patency, estimated total larval production and survival rate of D. Filaria producer lambs. The administration of I.V. O2 releaser and bronchodilator helped in efficiently restoring the altered values of blood pH, haemoglobin, packed cell volume, erythrocyte sedimentation rate and osmotic fragility of erythrocytes to near normal levels. However, the blood clotting time and level of lactate dehydrogenase activity remained altered and followed a course typical of ovine dictyocauliosis.

analysis of the transcriptome of adult Dictyocaulus Filaria and comparison with Dictyocaulus viviparus with a focus on molecules involved in host parasite interactions
International Journal for Parasitology, 2014Co-Authors: Stefano Mangiola, Neil D Young, Paul W Sternberg, Christina Strube, Pasi K Korhonen, Makedonka Mitreva, Jeanpierre Y Scheerlinck, Andreas Hofmann, Robin B GasserAbstract:Parasitic nematodes cause diseases of major economic importance in animals. Key representatives are species of Dictyocaulus (=lungworms), which cause bronchitis (=dictyocaulosis, commonly known as “husk”) and have a major adverse impact on the health of livestock. In spite of their economic importance, very little is known about the immunomolecular biology of these parasites. Here, we conducted a comprehensive investigation of the adult transcriptome of Dictyocaulus Filaria of small ruminants and compared it with that of Dictyocaulus viviparus of bovids. We then identified a subset of highly transcribed molecules inferred to be linked to host–parasite interactions, including cathepsin B peptidases, fatty-acid and/or retinol-binding proteins, β-galactoside-binding galectins, secreted protein 6 precursors, macrophage migration inhibitory factors, glutathione peroxidases, a transthyretin-like protein and a type 2-like cystatin. We then studied homologues of D. Filaria type 2-like cystatin encoded in D. viviparus and 24 other nematodes representing seven distinct taxonomic orders, with a particular focus on their proposed role in immunomodulation and/or metabolism. Taken together, the present study provides new insights into nematode–host interactions. The findings lay the foundation for future experimental studies and could have implications for designing new interventions against lungworms and other parasitic nematodes. The future characterisation of the genomes of Dictyocaulus spp. should underpin these endeavours.
