“…In a study carried out by Olah, van Wyk, Wall, and Morgan (), authors found a significant correlation between the FAMACHA© score in sheep and the presence of flukes in the liver ( r = .54, p < .001). However, in cattle naturally infected with F. gigantica and paramphistomes, the sensitivity and specificity of the FAMACHA© are low (Dorny et al., ; Elelu, Ambali, Coles, & Eisler, ).…”

Summary Fasciola hepatica is a trematode parasite with a global distribution, which is responsible for considerable disease and production losses in a range of food producing species. It is also identified by WHO as a re‐emerging neglected tropical disease associated with endemic and epidemic outbreaks of disease in human populations. In Europe, F. hepatica is mostly associated with disease in sheep, cattle and goats. This study reviews the most recent advances in our understanding of the transmission, diagnosis, epidemiology and the economic impact of fasciolosis. We also focus on the impact of the spread of resistance to anthelmintics used to control F. hepatica and consider how vaccines might be developed and applied in the context of the immune‐modulation driven by the parasite. Several major research gaps are identified which, when addressed, will contribute to providing focussed and where possible, bespoke, advice for farmers on how to integrate stock management and diagnosis with vaccination and/or targeted treatment to more effectively control the parasite in the face of increasing the prevalence of infection and spread of anthelmintic resistance that are likely to be exacerbated by climate change.

“…While FAMACHA is well established for sheep and goats, it has not yet been validated for cattle and calves. 5,10,11 Such a conjunctival redness scoring system has limited applications in cattle and calves, although some studies found that hematocrit is linearly correlated with FAMACHA scores in calves. 47 Indeed, we found no evidence of associations of conjunctival redness scores with blood Hgb levels in our study population.…”

Toward laboratory blood test-comparable photometric assessments for anemia in veterinary hematology

et al. 2016

Abstract. Anemia associated with intestinal parasites and malnutrition is the leading cause of morbidity and mortality in small ruminants worldwide. Qualitative scoring of conjunctival redness has been developed so that farmers can gauge anemia in sheep and goats to identify animals that require treatment. For clinically relevant anemia diagnosis, complete blood count-comparable quantitative methods often rely on complicated and expensive optical instruments, requiring detailed spectral information of hemoglobin. We report experimental and numerical results for simple, yet reliable, noninvasive hemoglobin detection that can be correlated with laboratory-based blood hemoglobin testing for anemia diagnosis. In our pilot animal study using calves, we exploit the third eyelid (i.e., palpebral conjunctiva) as an effective sensing site. To further test spectrometerfree (or spectrometerless) hemoglobin assessments, we implement full spectral reconstruction from RGB data and partial least square regression. The unique combination of RGB-based spectral reconstruction and partial least square regression could potentially offer uncomplicated instrumentation and avoid the use of a spectrometer, which is vital for realizing a compact and inexpensive hematology device for quantitative anemia detection in the farm field.

“…Although high prevalences of F. hepatica infection have been reported in dairy cattle in many countries (Mezo et al, 2008;Bennema et al, 2009Bennema et al, , 2010McCann et al, 2010), very few studies on their effects on milk production have been carried out, and results have not been consistent (Oakley et al, 1979;Khan et al, 2009Khan et al, , 2010. These discrepancies may be due to variations in the intensity of infection, as well as to differences among herds as regards genetics, nutritional and health factors, which all play an important role in determining the immune status of animals and the ensuing F. hepatica-associated morbidity (Dorny et al, 2010). Consequently, the impact of fasciolosis on farm productivity 0304-4017/$ -see front matter © 2011 Elsevier B.V. All rights reserved.…”
