“…Samples usually consisted of retropharyngeal, mediastinal, bronchial, mandibular, and mesenteric lymph nodes, lung, and liver collected at the post mortem examination. The samples received from four dead lynxes were a lesion at the elbow joint from an adult male (this first case has already been reported [4,39]), a lung with granulomatous lesions from a female (9) a ND, not done.…”

Bovine Tuberculosis ( Mycobacterium bovis ) in Wildlife in Spain

et al. 2004

Mycobacterium bovis infection in wildlife and feral species is a potential source of infection for livestock and a threat to protected and endangered species. The aim of this study was to identify Spanish wild animal species infected with M. bovis through bacteriological culture and spacer oligonucleotide typing (spoligotyping) of isolates for epidemiological purposes. This study included samples from red deer (Cervus elaphus), fallow deer (Dama dama), wild boar (Sus scrofa), Iberian lynx (Lynx pardina), hare (Lepus europaeus), and cattle (Bos taurus). They were collected in several geographical areas that were selected for their unique ecological value and/or known relationships between wildlife and livestock. In the areas included in this survey, M. bovis strains with the same spoligotyping pattern were found infecting several wild species and livestock, which indicates an epidemiological link. A locally predominant spoligotype was found in these areas. Better understanding of the transmission and distribution of disease in these populations will permit more precise targeting of control measures.

“…In Spain, a similar scenario may apply since two wild ungulate species, the red deer (Cervus elaphus) and the wild boar (Sus scrofa) have been reported to be infected with M. bovis [1,2,15,16,28]. In addition, cases of fatal tuberculosis have been described in endangered carnivores of the same region, such as the Iberian lynx (Lynx pardinus) [31]. To date, the magnitude of TB infection rates and distribution in wildlife in Spain, especially in potential reservoir species, remains unknown.…”

Wild boar and red deer display high prevalences of tuberculosis-like lesions in Spain

-We describe the distribution of tuberculosis-like lesions (TBL) in wild boar (Sus scrofa)and red deer (Cervus elaphus) in Spain. Animals with TBL were confirmed in 84.21% of mixed populations (n = 57) of red deer and wild boar and in 75% of populations of wild boar alone (n = 8) in central and southern Spain (core area). The prevalence of TBL declined towards the periphery of this region. In the core area, the prevalence ranged up to 100% in local populations of wild boar (mean estate prevalence 42.51%) and up to 50% in red deer (mean estate prevalence 13.70%). We carried out exploratory statistical analyses to describe the epidemiology of TBL in both species throughout the core area. Prevalence of TBL increased with age in both species. Wild boar and red deer mean TBL prevalence at the estate level were positively associated, and lesion scores were consistently higher in wild boars than in red deer. The wild boar prevalence of TBL in wild boar did not differ between populations that were or were not cohabiting with red deer. Amongst the wild boars with TBL, 61.19% presented generalized lesions, and the proportion of generalized cases was similar between sex and age classes. In red deer, 57.14% of TBL-positive individuals presented generalized lesions, and the percentage of generalized cases increased with age class, but did not differ between the sexes. These results highlight the potential importance of wild boar and red deer in the maintenance of tuberculosis in south central Spain.Mycobacterium tuberculosis complex / tuberculosis-like lesions / red deer / Spain / wild boar

“…In Doñ ana National Park (DNP), M. bovis has been confirmed in wild boar (Sus scrofa), fallow deer (Dama dama) (Leó n- Vizcano et al, 1991), Iberian lynx (Lynx pardinus) (Briones et al, 2000;Pé rez et al, 2001), and red fox (Vulpes vulpes) (Martn-Atance et al, 2005). The objective of this study was to describe the serological status of wild carnivores to determine the extent of prior exposures to M. bovis.…”

“…The transmission of M. bovis between wildlife and domestic livestock can be a major obstacle to bovine tuberculosis (BT) eradication in many countries (Clifton-Hadley et al, 1995b;O'Neil and Pharo, 1995;White & Harris, 1995). Bovine tuberculosis has been reported in wild carnivore species and it is well established that European badgers (Meles meles) are susceptible (Ragg et al, 1995;Keet et al, 1996;Gavier-Widen et al, 2001;Pé rez et al, 2001).…”

“…The relative frequency values may be useful to determine which species are at risk for M. bovis infection in DNP; for example, prevalence of M. bovis MPB70 antibodies in badgers is very high compared to red fox. In the case of the lynx, only one seropositive animal was detected and another lynx died with a generalized M. bovis infection (Pé rez et al, 2001). These observations suggest that lynx may represent an incidental host for M. bovis.…”

ABSTRACT:We conducted a retrospective serologic survey for antibodies against the MPB70 protein of Mycobacterium bovis in wild carnivores from Doñ ana National Park (southwestern Spain). Serum samples from 118 red foxes (Vulpes vulpes), 39 Iberian lynx (Lynx pardinus), 31 Eurasian badgers (Meles meles), five Egyptian mongoose (Herpestes ichneumon), four European genet (Genetta genetta), and one Eurasian otter (Lutra lutra) were analyzed using an indirect competitive enzyme-linked immunoassay. Antibodies against the MPB70 protein of M. bovis were detected in seven badgers, five foxes, and one lynx. The frequency of positive animals was significantly higher in badger (23%) than in lynx (3%) and fox (4%). Antibodies were not detected in other species. Annual antibody frequency peaked at 38% in badgers and 11% for red fox. These species may contribute to persistence of bovine tuberculosis in Doñ ana.
