The relationship between the number and size of nematodes in the abomasum and the concentration of pepsinogen in ovine plasma
(1999-08)
Six-month-old lambs that had been naturally infected with predominantlyTeladorsagia (Ostertagia) circumcinctawere tested for plasma pepsinogen concentrations because pepsinogen concentrations may reflect the extent of ...
How hosts control worms
(1997-09-04)
Nematodes are a major cause of disease and death in humans, domestic animals and wildlife. Understanding why some individuals suffer severely whereas others exposed to the same infection remain healthy may assist in the ...
The genetic basis of resistance to Ostertagia circumcincta in lambs
(1997-09)
The relationship between Ostertagia (Teladorsagia) circumcincta and sheep is one of the best understood host-parasite relationships in any species. The key components of resistance have been quantified, the extent of genetic ...
Genetic parameters for faecal egg count following mixed, natural, predominantly Ostertagia circumcinta infection and relationships with live weight in young lambs
(1996-12)
Faecal egg counts and live weights were measured on approximately 200 predominantly twin-born Scottish Blackface lambs each year for 3 years, from 2 to 6 months of age. Measurements were made at 4-week intervals following ...
An ovine lymphocyte antigen is associated with reduced faecal egg counts in four-month-old lambs following natural, predominantly Ostertagia circumcincta infection
(1996-04)
Ten lymphocyte antigens were defined in a flock of Scottish Blackface sheep known to be naturally exposed to infection with Ostertagia circumcincta. Population and family studies suggested that the 10 antigens were products ...
The repeatability of faecal egg counts, peripheral eosinophil counts, and plasma pepsinogen concentrations during deliberate infections with Ostertagia circumcincta
(1995-03)
Faecal egg counts, peripheral blood eosinophil counts and plasma pepsinogen concentrations were monitored during 2 successive, deliberate infections in 24 Scottish Blackface sheep. For all 3 techniques, the repeatability ...
