“…Therefore, it is unlikely that fox populations in the three sites were limited by the level of culling. The impact of culling on fox populations is much debated, especially on large geographical scales (Hewson 1986;Baker et al 2004;Baker et al 2002;Aebischer et al 2003), and conclusions of those studies are contrasted. One of the key points explaining these contrasting results may be the various levels of culling effort applied in relation to fox densities.…”

We tested a staining method on uteri for counting placental scars on red fox. We estimated reproduction parameters on 358 females collected in three study areas in western France from 1st February 2002 to 31st January 2005. Placental scars (n=103) were described by macroscopic examinations using the following variables: (1) the width and (2) the aspect of placental scars, (3) the abundance of macrophages or the presence of blood, (4) the presence of swellings, (5) the presence and colour of a central band and (6) the presence and colour of lateral bands. A factorial correspondence analysis showed strong associations between the month when scars were examined and categories of variables. Staining on placental scars made macrophages more visible, facilitating identification of 'active' placental scars, i.e. related to the last pregnancy. However, distinction between placental scars due to earlier pregnancies and resorptions was not possible. The staining method used provides a standard that could be useful for obtaining comparable and repeatable results. The mean number of placental scars was 4.85±1.46 (n=103) per vixen. The mean number of embryos per vixen was 4.66± 1.35 (n=68) for yearlings and 5.53±1.50 (n=96) for older females. Including percentages of barren vixens, the total population productivity was significantly smaller for yearlings (3.62±1.86, n=158) than for older females (4.28± 1.75, n=186). We discuss these results in relation to fox densities, culling and food availability.

“…In Eastern Hokkaido (Japan), hunting was increased in 1970 but despite that, the parasite is still present although at a low prevalence. A nation-wide hunting ban on foxes in the United Kingdom was reported not to have measurable impact on the fox population density in selected areas (Baker et al, 2002 cited by Kamiya et al, 2007). Kamiya et al (2007) concluded that fox hunting by culling or trapping does not have an effect on the number of foxes and therefore no effect on controlling EM.…”

Full terms of use are available: http://www.bristol.ac.uk/pure/about/ebr-terms carnivore species can maintain the lifecycle in the absence of red fox, and this makes it to most relevant target species for surveillance. Movement of infected definitive hosts is an important introduction pathway. The knowledge on the geographical distribution of the environmental factors for the persistence of the lifecycle is scarce. In areas where no suitable autochthonous wild canid hosts and no highly suitable intermediate hosts are present, e.g. Malta, establishment of the EM cycle is considered close to impossible. Such countries do not need to carry out surveillance on domestic dogs to substantiate absence of EM in the relevant animal population. Reconsideration of some aspects of the current legislation regarding surveillance activities might be relevant; for example the identification of epidemiologically relevant units should be independent from political borders. Studies to improve the knowledge on epidemiological risk factors should be encouraged to enable risk-based sampling. Echinococcus notification should always be done at species level in order to discriminate between the more severe alveolar echinococcosis and the cystic echinococcosis. Praziquantel is the substance of choice for the treatment of dogs. However, the treatment window should be reconsidered to reduce the risk of re-infection: a general rule is to treat as close as possible to entry into a non-infected country. There is a lack of standardization of the diagnostic methods between laboratories. The diagnostic sensitivity of the tests should be established in accordance to the World Organisation for Animal Health (OIE) standards for validation. For the time being, the diagnostic sensitivity can be set conservatively to 78%.

E. multilocularis infections in animalswww.efsa.europa.eu/efsajournal 3 EFSA Journal 2015;13(15):4373 SummaryHuman alveolar echinococcosis (AE) is caused by the larval stage of the fox tapeworm Echinococcus multilocularis. It is amongst one of the most dangerous zoonoses. Naturally the parasite transmits between foxes or dogs and small mammals whilst humans are aberrant intermediate hosts.In rodents, the larval mass proliferates rapidly by exogenous budding of germinative tissue and produces an alveolar-like pattern of microvesicles filled with protoscolices. In humans, the larval mass resembles a malignancy in appearance and behavior, because it proliferates indefinitely by exogenous budding and invades the surrounding tissues (Moro et al., 2008). Transmission of A...

“…1 The obvious point here is that 'country sports' is a broad church, and the chapter focuses upon recent social science empirical research on hunting. There is, of course, an important natural science literature in relation to foxes (see Harris 1993, Baker et al 2002 and game shooting (see GCT 2005), in addition to reflections by participants themselves (Sassoon 1999, Shilling 2004). However, the chapter seeks to challenge whether has a case that the academic community has evaluated the country sport of hunting via its own, dominant methodological paradigm and according to the agenda of the government, rather than seeking to explore the phenomena of hunting a priori.…”
