A new method for the interpretation of strongyloid egg counts in faeces in sheep flocks is proposed. The "Flock Parasitism Index" (FPI) is based on three epizootiological concepts: extent of parasitism, distribution of its intensity, and risk of pasture contamination by eggs. In the estimation of FPI from a number of faecal samples from different animals in a flock, the percentage of parasitized sheep and the distribution of parasitized animals of the sample into the classical categories of… Expand

TLDR
It is disappointing to find that some of my work should be misrepresented in one of the features of the Feature Review Series. Expand
Coprological detection of equine nematodes among slaughtered donkeys (Equus asinus) in Kaltungo, Nigeria
TLDR
The preponderance of light infection may suggest that donkeys in this environment developed resistance to nematode infection and are potential reservoirs for other equines. Expand
Agricultural restructuring and gastrointestinal parasitism in domestic ruminants on the rangelands of Kazakhstan.
TLDR
It is suggested that cessation of strategic nematode control in the region following post-Soviet agricultural reform was offset by a general reduction in stocking density, such that parasite burdens remained low, and recovery in livestock numbers is likely to lead to increased levels of infection and production loss unless sustainable control strategies are put in place.

Association of endoparasites and productivity of highland sheep in Ethiopia
TLDR
It is confirmed that body weight is directly and inversely related to PCV and EPG counts, respectively, and sex had no effect on EPG and PCV, although females had lower body weights and body condition scores. Expand
Determining the impact of protozoan and strongylid parasites on meat lamb productivity: Utilising molecular diagnostic methods for the detection of internal parasites in lambs
TLDR
A novel, possibly new genotype (sheep genotype I) was identified in six Cryptosporidium isolates from Arthur River, and a new innovative, molecular approach was developed to recover strongylid larvae from pasture, which had a strong, negative correlation with traditional diagnostic methods. Expand
Use of pooled faecal samples in assessing nematode egg shedding in captive gazelles (Gazella species)
TLDR
Pregnant pigs after alteration of litter size during late lactation and the effects of the time ofweaning and its effects of reproductive functions are studied. Expand
Molecular identification of naturally acquired strongylid infections in lambs--an investigation into how lamb age influences diagnostic sensitivity.
TLDR
Results indicate thatstrongylid eggs were likely to be the main source of strongylid DNA in the faecal DNA extracts and there is potential for further investigation into the development of a similar molecular procedure which could be used for early larvae detection on pastures. Expand
ASPECTS OF ANTHELMINTIC RESISTANCE IN NEMATODES OF SHEEP
  • 2017
The increasing prevalence of anthelmintic resistance in nematodes of sheep is causing concern among animal scientists and farmers. In Australia anthelmintic resistance has become widespread since theExpand
Effects of a second annual strategic anthelmintic treatment in dairy sheep in Northern Spain
TLDR
A strategy where ewes are treated at lambing and pre-mating would be the best alternative since the highest economic benefits are obtained in addition to an efficient reduction in parasite burdens. Expand

TLDR
The relationship between the strongyle egg count and the total strongyle worm burden and the “total pathogenic index” (T.P.I) of the worm burden in 190 “young” and 131 “old” sheep was examined, finding the association between them was found to be almost equally consistent in both age classes of stock.

Herd immunity to helminth infection and implications for parasite control
TLDR
A simple mathematical model is described which mirrors the development of a degree of acquired immunity within populations which are genetically heterogeneous with respect to immunological responsiveness and suggests that effective parasite control by vaccination is difficult to achieve in communities that are geneticallyheterogeneous in their ability to mount protective responses to infection.
