Carriage of pathogenic Leptospira in carnivores at the wild/domestic interface.

The carriage of pathogenic Leptospira was investigated by PCR in 51 wild carnivores, 20 domestic dogs with outdoor access, and 27 free-roaming domestic cats sampled in periurban Barcelona (NE Spain). Overall prevalence was 7.7%, with DNA confirmed in 3/30 common genets (Genetta genetta) (serovars Icterohaemorraghiae and Sejröe), 1/9 red foxes (Vulpes vulpes) (Canicola) and 2/27 cats (Icterohaemorraghiae).

Risk factors of Leptospira infection in Mediterranean periurban micromammals.

Urbanization of natural areas can change abiotic factors, providing artificial sources of humidity in summer and decreasing variation of temperatures in winter. Our study aimed at document risk factors of infection in mammal reservoirs of pathogenic Leptospira in the human/wildlife interface of a large metropolitan area. We hypothesize that survival of Leptospira and thus their prevalence in animal reservoirs should be higher in residential areas than in natural habitats, especially after the hot, dry Mediterranean summers.

Using a top predator as a sentinel for environmental contamination with pathogenic bacteria: the Iberian wolf and leptospires.

The Iberian wolf (Canis lupus) is the top predator in the Iberian environments in which it lives, feeding on a wide range of species, thus encountering a wide range of disease agents. Therefore, the wolf can serve as sentinel of environmental contamination with pathogens. We investigated the exposure of free-living wolves to 14 serovars of Leptospira interrogans sensu lato.

Management of a caseous lymphadenitis outbreak in a new Iberian ibex (Capra pyrenaica) stock reservoir.

Background: In 2010, an Iberian ibex (Capra pyrenaica hispanica) stock reservoir was established for conservation purposes in north-eastern Spain. Eighteen ibexes were captured in the wild and housed in a 17 hectare enclosure. Once in captivity, a caseous lymphadenitis (CLA) outbreak occurred and ibex handlings were carried out at six-month intervals between 2010 and 2013 to perform health examinations and sampling.

Detection of antibodies in wild ruminants to evaluate exposure to liver trematodes.

Wild ruminants sharing pastures with domestic livestock are at risk of infection by liver trematodes. Detection of antibodies provides a very useful tool to gain more knowledge about the distribution of these parasites. Non-lethal methods are strongly encouraged for the analysis of the risk of infection among wild ruminants.

Use of a crude extract or purified antigen from first-instar cattle grubs, Hypoderma lineatum, for the detection of anti-Hypoderma antibodies in free-ranging cervids from southern Spain.

During the 2003-2005 hunting seasons, a total of 120 Cervidae, including 39 red deer (Cervus elaphus hispanicus) and 81 fallow deer (Dama dama), were examined for subcutaneous myiasis. Animals were shot from January to June in southern Spain. Specific antibodies against Hypodermatinae (Diptera: Oestridae) were detected by indirect enzyme-linked immunosorbent assay (iELISA) using a crude larval extract (CLE) and a purified antigen [hypodermin C (HC)] obtained from first instars of Hypoderma lineatum (De Villers) (Diptera: Oestridae).

Importance of canine distemper virus (CDV) infection in free-ranging Iberian lynxes (Lynx pardinus).

Canine distemper virus (CDV) is a morbillivirus that is the etiological agent of one of the most important viral diseases affecting canids and an expanding range of other carnivores. Using real-time RT-PCR, CDV RNA was detected in organs of an Iberian lynx (Lynx pardinus) found dead in the Doñana National Park, Southwestern Andalusia, Spain. This finding may be of great importance for the conservation of the species; at present the Iberian lynx is the most critically endangered wild felid.

Leptospirosis in wild and domestic carnivores in natural areas in Andalusia, Spain.

Leptospirosis is a zoonosis that affects humans, domestic animals, and wildlife. Carnivores are at the top of the feeding chain, thus being exposed to pathogens through their preys. From June 2004 to April 2007, we analyzed for evidences of contact with 14 serovars of Leptospira interrogans Sensu Lato serum (analyzed by indirect Microscopic Agglutination Test) and urine or kidney samples (analyzed by microscopic observation, immunostaining and culture) collected from 201 wild and domestic carnivores, including 26 free-living Iberian lynx (Lynx pardinus), 33 red foxes (Vulpes vulpes), 33 Egyptian mongooses (Herpestes ichneumon), 25 common genets (Genetta genetta), two Eurasian badgers (Meles meles) and one Eurasian otter (Lutra lutra), and 53 free-roaming cats and 28 rural dogs in protected areas in Andalusia (southern Spain).

Disseminated bovine tuberculosis in a wild red fox (Vulpes vulpes) in southern Spain.

A wild-caught, adult red fox (Vulpes vulpes) from Doñana National Park (southern Spain), in very poor condition, died during anesthesia. At necropsy, the submandibular, retropharyngeal, mediastinal, axillary, mesenteric, and popliteal lymph nodes were enlarged, and the right submandibular and mesenteric lymph nodes had hard, white-colored concretions (calcifications). Multiple white pinpoint foci were observed in the lungs, and abscesses were present in the left dorsal lung lobes.

Disease threats to the endangered Iberian lynx (Lynx pardinus).

The Iberian lynx, (Lynx pardinus), is the most endangered felid in the world. To determine whether sympatric carnivores are reservoirs of pathogens posing a disease risk for the lynx, evidence of exposure to 17 viral, bacterial and protozoan agents was investigated in 176 carnivores comprising 26 free-living lynx, 53 domestic cats, 28 dogs, 33 red foxes (Vulpes vulpes), 24 Egyptian mongooses (Herpestes ichneumon), 10 common genets (Genetta genetta) and 2 Eurasian badgers (Meles meles) in the areas inhabited by the last two populations of Iberian lynx, both in Andalusia (South-Western Spain). The results indicated that the lynx had low rates of contact with viral pathogens, with one seropositive finding each for feline leukemia virus, parvovirus and canine adenovirus-1, whereas contact with bacteria and protozoa appeared more frequent.

Epidemiology of Mycoplasma agalactiae infection in free-ranging Spanish ibex (Capra pyrenaica) in Andalusia, southern Spain.

Mycoplasma agalactiae is the main causal agent of contagious agalactia syndrome in Spain. It is a severe disease of small ruminants, endemic in Mediterranean countries, that is characterized by mastitis, arthritis, and keratoconjunctivitis. This paper investigates the temporal, spatial, and host-related factors in the distribution of M.

Exposure to disease agents in the endangered Iberian lynx ().

The Iberian lynx () is the most endangered felid species in the world. Lynx populations have decreased dramatically in size and distribution in the last four decades, thus becoming increasingly vulnerable to catastrophic events such as epizooties. From 1989 to 2000, serum samples were obtained from 48 free-ranging lynx captured in the Doñana National Park (DNP,  = 31) and mountains of Sierra Morena (SM, n = 17) in southern Spain.

Antibodies to Mycobacterium bovis in wild carnivores from Doñana National Park (Spain).

We conducted a retrospective serologic survey for antibodies against the MPB70 protein of Mycobacterium bovis in wild carnivores from Doñana 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.

Potential pathogens carried by Spanish ibex (Capra pyrenaica hispanica) in southern Spain.

The Spanish ibex (Capra pyrenaica hispanica) population of southern Spain was surveyed for potential pathogens associated with the conjunctiva, external ear canal, as well as reproductive and upper respiratory tracts. We sampled 321 ibex (131 adult males, 100 adult females, and 90 yearlings); these included 271 apparently healthy animals and 50 that were naturally infected with Sarcoptes scabiei. A total of 688 bacterial isolates were identified (377 gram-negatives, 225 gram-positives, and 86 Mycoplasma spp.

The translation into Spanish of the OIE Manual of diagnostic tests and vaccines for terrestrial animals (mammals, birds and bees): problems, solutions and conclusions.

In order to carry out the translation into Spanish of the Manual of diagnostic tests and vaccines for terrestrial animals (mammals, birds and bees) ensuring full scientific and linguistic accuracy, its authors relied on coordination between three types of experts: linguistic, translational and veterinary. In this paper the planning, execution and quality control of such work, which was undertaken with the support and guarantee of the World Organisation for Animal Health (OIE), is reported. In the conclusions the authors describe what they view as necessary guidelines for the OIE to apply in the future regarding its linguistic policy.

Bovine tuberculosis in a free ranging red fox (Vulpes vulpes) from Doñana National Park (Spain).

During 1997 and 1998, a survey of Iberian carnivores was conducted to study the epidemiology of bovine tuberculosis in the Doñana National Park and surrounding areas in southwestern Spain. Post-mortem examinations were done on seven red foxes (Vulpes vulpes), two Egyptian mongoose (Herpestes ichneumon), one weasel (Mustela nivalis), two genets (Genetta genetta), one Iberian lynx (Lynx pardinus), one Eurasian badger (Meles meles), and two polecats (Mustela putorius). Lesions suggestive of bovine tuberculosis were not detected but, in culture, Mycobacterium bovis was isolated from the retropharyngeal lymph nodes of one adult male red fox.

Population effects of sarcoptic mange in Barbary sheep (Ammotragus lervia) from Sierra Espuña Regional Park, Spain.

The nonindigenous Barbary sheep population (Ammotragus lervia) of the Sierra Espuna Regional Park (Murcia, Spain) suffered an outbreak of sarcoptic mange between 1991 and 1995, which contributed to a population decrease of 86%. This study presents the results of two population surveys conducted in 1994 and 1999 based on the fixed point and itineraries method (FPI) and the excrement count (EC) method, as well as data from demographic estimates and clinical observations conducted by the Regional Administration of Murcia. Results of surveillance for mange are given between 1992 and 1995, because no animals were observed with sarcoptic mange in 1999.

Antibodies to selected viral and bacterial pathogens in European wild boars from southcentral Spain.

Serum samples from 78 European wild boars (Sus scrofa) harvested during the 1999-2000 hunting season were tested for antibodies to Brucella spp., classical swine fever virus, Erysipelothrix rhusiopathiae, Haemophilus parasuis, Leptospira interrogans serovar pomona, Mycoplasma hyopneumoniae, pseudorabies virus (PRV), porcine parvovirus (PPV), porcine reproductive and respiratory syndrome virus, Salmonella serogroups B, C, and D, Streptococcus suis, and swine influenza virus (SIV) serotypes H1N1 and H3N2. Samples were collected from Sierra Morena and Montes de Toledo in southcentral Spain.

Experimental ivermectin treatment of sarcoptic mange and establishment of a mange-free population of Spanish ibex.

Ivermectin was used to treat sarcoptic mange in Spanish ibex (Capra pyrenaica hispanica). Its therapeutic effectiveness was analyzed when it was administered through subcutaneous injection, to sick animals in the consolidation stage of mange (third phase) and, with double injections to chronically affected animals (fourth phase) at a dosage of 0.2 or 0.

Seroepidemiology of chlamydial infections of wild ruminants in Spain.

Chlamydial infections were determined serologically among wild ruminants in the Nature Park of the Sierras de Cazorla, Segura y Las Villas (CNP; Spain). Sampling was done during the period from 1990-95. There were 1,244 blood samples collected, consisting of 490 from fallow deer (Dama dama), 343 from mouflon (Ovis mussimon), 283 from red deer (Cervus elaphus) and 128 from Spanish ibex (Capra pyrenaica).

Sarcoptic mange in Spanish ibex from Spain.

The Spanish ibex (Capra pyrenaica hispanica) population of the "Sierras de Cazorla, Segura y Las Villas" Nature Park (Spain) was isolated as the result of a severe epidemic of sarcoptic mange. In this context, the dynamic characteristics of the disease were analyzed in a wild group consisting of 35 animals from the beginning of the epizootic (when the mating period started) to the extinction of the population due to mange. Monthly tracking permitted the sequential characterization of the pathology in each animal.
