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. Prevalence of mange peaked in 1994 and then declined. During the regression phase of the epidemic, there was a higher infection rate in males (21.9%) than in females (16.6%) or young animals (5.1%). Males over 5 yr old were the worst affected age group, followed by subadults of both sexes. Few animals had generalized lesions of mange (7%), and most individuals (72%) had lesions of moderate severity. The most common locations of lesions were the neck, head, and back. The density of Barbary sheep in the Sierra Espuna Regional Park increased from introduction in 1972 until it peaked at 13 animals/km(2) in 1991, the year when the first case of sarcoptic mange was detected. After 2 yr of the mange epidemic, the average estimated density was 1.7 animals/km(2) in 1994, which increased to 5.0 animals/km(2) in 1999. The average group size also increased from 7.9 to 19.2 animals/group between 1994 and 1999. The sex ratio, expressed as the proportion of females in the total population observed, decreased from 0.61 in 1994 to 0.49 in 1999. The reproduction rate (kids per females per year) was essentially stable (0.59 in 1994 to 0.65 in 1999). Between 1994 and 1999 the population aged, with the number of young animals (<18 mo of age) decreasing from 45.3% to 36.6% from 1994 to 1999. In the same period, the proportion of males increased 21.4% to 32.6%. We believe sarcoptic mange acted as one of the regulating factors of population density after 1991 and that currently, although no sarcoptic mange lesions were observed in the 1999 survey, there is a demographic imbalance in sex ratio, age structure, and density.

Despite public concern on the role of free‐roaming cats as reservoirs of zoonotic agents, little is known about the influence of urban and peri‐urban landscapes on the exposure risk. We evaluated the seroprevalence of three zoonotic agents (Chlamydia felis, Coxiella burnetiiandToxoplasma gondii) in domestic cats (Felis catus). Two hundred and ninety‐one free‐roaming cats were trapped in Murcia municipality (Southeast Spain), and their sera were tested for specific antibodies againstT. gondiiusing a modified agglutination test (MAT), and forC. felis,C. burnetiiand feline immunodeficiency virus (FIV) antibodies with ELISA technique. Pathogen seroprevalence at 95% CI was calculated for each sex and age category (up to and over 12 months) and compared with a chi‐squared test. The role of human population density and urban landscape characteristics on the risk of pathogen exposure in the cat population was explored using generalized linear models. Seropositivity against a single pathogen was found in 60% of the cats, while 19% was seropositive for two or three pathogens. Seroprevalence ofC. feliswas 8% (CI95%: 5–11), 37% (CI95%: 31–42) forC. burnetiiand 42% (CI95%: 36–47) forT. gondii. In addition to these three pathogens, FIV seropositivity was low (1%, CI95%: −0.1 to 2) and adult cats were more likely to be seropositive toC. burnetiithan young individuals (OR: 2.3, CI95%: 1.2–4.2). No sex or age class differences in seroprevalence were observed for the rest of the pathogens. Seropositivity was correlated with water surface areas forC. felis,and not with crop areas.Coxiella burnetiiseropositivity was correlated with the percentage of urban areas (continuous with only buildings and discontinuous, that include buildings, parks, and pedestrian and urban green areas), human population size and peri‐urban areas with shrubs, and not correlated with other agricultural landscapes (orchards and crop areas). However, the seroprevalence ofT. gondiiwas only associated with agricultural landscapes such as orchards. The detection of hotspot areas of high pathogen exposure risk is the basis for municipal services to implement surveillance and risk factor control campaigns in specific‐risk areas, including (a) efficient health management of urban cat colonies by geographical location, population census and health status monitoring of the components of each cat colony, (b) improvement of hygiene and sanitary conditions at the feeding points of the cat colony and (c) free‐roaming cat trapping for health monitoring and, in the long term, to know the evolution of the health status of their populations.

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.); sex, age, location, infection with S. scabiei, and disposition of the animal (free-ranging versus captive) were evaluated as risk factors for infection. Infections with Mycoplasma agalactiae and Mycoplasma arginini were associated with age, having a higher frequency of isolation in young animals. With Escherichia coli, Mannheimia haemolytica, Pasteurella multocida biotype A, and Staphylococcus aureus, significantly higher isolation rates were associated with adults. The isolation frequency for E. coli was higher in females, whereas Moraxella bovis isolations were mostly associated with males. The presence of mange increased the risk of infection with both Streptococcus equi subsp. zooepidemicus and M. haemolytica. The geographic origin of sampled animals was related to the isolation of Branhamella ovis, M. agalactiae, and all Pasteurella sp. Isolations of M. haemolytica, P. multocida biotype A, E. coli, and B. ovis were more prevalent in samples from free-ranging rather than captive animals. Of the gram-positive bacteria, S. aureus represented the predominant species isolated from nasal, vaginal, and ocular samples. Mycoplasma agalactiae and M. arginini were the predominant Mycoplasma spp., and both were associated most often with the external ear canal. The most frequently isolated gram-negative bacteria included E. coli, M. haemolytica, P. multocida biotype A, and B. ovis. Isolation rates of gram-negative species varied by source. In nasal samples, M. haemolytica and P. multocida biotype A were isolated most frequently, whereas in ocular and vaginal samples, B. ovis and E. coli, respectively, were most frequently isolated.

SUMMARY: Assessment of the role of wild and domestic hosts as potential reservoirs of misdiagnosed zoonoses, such as Q fever byCoxiella burnetii, is an important public health issue today both for wildlife conservation and management of disease in human–livestock–wildlife interface. This study used ELISA, an indirect antibody, to research (2003–2013)C. burnetiiinfection in seven free-living wild and domestic ruminant species and in European wildcats (Felis silvestris). The animals studied were 0 European wildcats, 21 Spanish ibex (Capra pyrenaica), 314 red deer (Cervus elaphus), 556 fallow deer (Dama dama), 211 European mouflon (Ovis aries musimon), eight roe deer (Capreolus capreolus), 407 bovines (Bos taurus) and 3739 sheep (Ovis aries). All the animals shared the same habitat in the Serranía de Cuenca Natural Park (Castile-La Mancha, Spain). The study area is an example of human–domestic–wildlife interface where people and domestic animals live in close proximity to wildlife. ObservedC. burnetiiseropositive frequencies were: 33·3% European wildcats, 23·8% Spanish ibex, 22·5% domestic sheep 1·5% red deer, 1·4% European mouflon, 0·24% cattle, 0·18% fallow deer and 0% roe deer. The study found a wideC. burnetiiprevalence of previous and present exposure in wild and domestic ruminant hosts in the Serranía de Cuenca Natural Park and reports the first evidence ofC. burnetiiexposure in free-living European wildcats.
