Badgers and bovine tuberculosis
نویسنده
چکیده
falsify a molecular phylogeny based on evidence from geographic or morphological evidence. However, a phylogeny reconstructing extinct relationships, which usually did not preserve molecular evidence, is difficult to falsify. When studying paleontology, constructing phylogenetic hypotheses is important, yet we are always struggling in debates over which phylogenetic cladogram is closest to the truth.

Bovine tuberculosis in cattle and badgers in localized culling areas.
Bovine tuberculosis (TB) is a zoonotic disease that can have serious consequences for cattle farming and, potentially, for public health. In Britain, failure to control bovine TB has been linked to persistent infection of European badger (Meles meles) populations. However, culling of badgers in the vicinity of recent TB outbreaks in cattle has failed to reduce the overall incidence of cattle TB...
متن کاملBadger social networks correlate with tuberculosis infection
Although disease hosts are classically assumed to interact randomly [1], infection is likely to spread across structured and dynamic contact networks [2]. We used social network analyses to investigate contact patterns of group-living European badgers, Meles meles, which are an important wildlife reservoir of bovine tuberculosis (TB). We found that TB test-positive badgers were socially isolate...
متن کاملTuberculosis in European badgers (Meles meles) and the control of infection with bacille Calmette-Guérin vaccination.
The eradication of tuberculosis (Mycobacterium bovis infection) from cattle herds may be compromised if infected wildlife species, such as European badgers (Meles meles), share the same environment and contribute to transfer of infection. Options for dealing with tuberculosis in this wild reservoir host are limited by conservation and social concerns, despite a clear implication that infected b...
متن کاملTuberculosis in badgers; a review of the disease and its significance for other animals.
This review examines the current state of knowledge of aspects of tuberculosis in the badger. The gross pathology and pathogenesis are elaborated as well as the immune mechanism, diagnosis of infection and excretion and viability of infected products. The epidemiology in badgers is considered, as is the significance of infection in this species for other wildlife species as well as domestic ani...
متن کاملThe prevalence, distribution and severity of detectable pathological lesions in badgers naturally infected with Mycobacterium bovis.
The Randomized Badger Culling Trial (RBCT) began in 1998 to determine the impact of badger culling in controlling bovine tuberculosis in cattle. A total of 1166 badgers (14% of total) proactively culled during the RBCT were found to be tuberculous, offering a unique opportunity to study the pathology caused by Mycobacterium bovis in a large sample of badgers. Of these, 39% of adults (approximat...
متن کاملBacillus Calmette-Guérin vaccination reduces the severity and progression of tuberculosis in badgers.
Control of bovine tuberculosis (TB) in cattle has proven particularly challenging where reservoirs of infection exist in wildlife populations. In Britain and Ireland, control is hampered by a reservoir of infection in Eurasian badgers (Meles meles). Badger culling has positive and negative effects on bovine TB in cattle and is difficult, costly and controversial. Here we show that Bacillus Calm...
