Microbial Infections

Microbial infections that affect reproduction are poorly studied in wildlife because reproductive disorders usually go unnoticed. However, such infections are a major concern in domestic ungulates, which raises the question of their influence on reproductive success and population dynamics of wild ungulates. Three bacterial abortive infections are frequent in domestic ruminants: salmonellosis caused by Salmonella enterica serovar Abortusovis, enzootic abortion caused by Chlamydophila abortus , and Q fever caused by Coxiella burnetii . They induce abortions and neonatal mortality in sheep ( Ovis aries L., 1758), goat ( Capra hircus L., 1758), and cattle ( Bos taurus L., 1758). However, little information is known about these bacteria in wild ungulates, particularly in mountain ungulates that may share alpine pastures with infected domestic ruminants. We investigated the relationship between female serological status against Salmonella, Chlamydophila, and Coxiella and her reproductive success. From 1986 to 2003, the reproductive and serological statuses of 125 female chamois ( Rupicapra rupicapra (L., 1758)) aged 2–10 years were available. Reproductive success was the lowest for 2-year-old females and for females born at the highest density. Moreover, we showed for the first time in a wild ungulate population that females with high titer in antibodies against Salmonella experienced a decrease in their reproductive success. Titers in antibodies against Chlamydophila and Coxiella were not related to the reproductive success of female chamois.

This study aimed to investigate the seroprevalence of C. burnetii in domestic ruminants, wild ungulates, as well as the current situation of Q fever in humans in a small region in northwestern Spain where a close contact at the wildlife–livestock–human interface exists, and information on C. burnetii infection is scarce. Seroprevalence of C. burnetii was 8.4% in sheep, 18.4% in cattle, and 24.4% in goats. Real-time PCR analysis of environmental samples collected in 25 livestock farms detected Coxiella DNA in dust and/or aerosols collected in 20 of them. Analysis of sera from 327 wild ungulates revealed lower seroprevalence than that found in domestic ruminants, with 8.4% of Iberian red deer, 7.3% chamois, 6.9% fallow deer, 5.5% European wild boar and 3.5% of roe deer harboring antibodies to C. burnetii. Exposure to the pathogen in humans was determined by IFAT analysis of 1312 blood samples collected from patients admitted at healthcare centers with Q fever compatible symptoms, such as fever and/or pneumonia. Results showed that 15.9% of the patients had IFAT titers ≥ 1/128 suggestive of probable acute infection. This study is an example of a One Health approach with medical and veterinary institutions involved in investigating zoonotic diseases.

The article discusses osteological material from the excavations of the Shengeldy caravanserai. In the descriptions of the representatives of the fauna from the medieval caravanserai of Shengeldy and in table 1, the majority of bone remains are identified to a species. Examination of the species composition of the fauna shows their not rich species composition, although as a result of the study all species of domestic ungulates are found. Bone remains were determined by species, skeleton elements and degree of fragmentation. Bones found: horses (Equus caballus), cattle (Bos taurus), sheep (Ovis aries), goats (Capra hircus) and camel (Camelus bactrianus); wild animals - kulan (Equus hemionus), saiga (Saiga tatarica) and turtles (Testudines). Among domestic animals, the bones of horses and small cattle prevail. Cattle ranks third in number. One camel bone was found. Of the bones of domestic animals, 23.4% were intact and 76.6% were fragmented. Among the departments of the skeleton of domestic ungulates, carcass bones (scapula, vertebrae, ribs) and upper legs (femurs and tibia) predominate. Several fragments of human bones were found. Morphometric studies of the bones of horses, sheep, goats and cattle were carried out. Geometric morphometric methods have revealed morphological differences and similarities between species.

Identification Analysis

A PCR assay has been developed for the specific and qualitative detection of pork ( Sus scrofa domesticus), beef ( Bos taurus), sheep ( Ovis aries), and goat ( Capra hircus) in raw and heat-treated meat mixtures. A forward common primer was designed on a conserved DNA sequence in the mitochondrial 12S ribosomal RNA gene (rRNA), and reverse primers were designed to hybridize on species-specific DNA sequences of each species considered. The different sizes of the species-specific amplicons, separated by agarose gel electrophoresis, allowed clear species identification. Analysis of experimental meat mixtures demonstrated that the detection limit of the assay was 1% (wt/wt) for each species analyzed. This assay can be useful for the accurate identification of these species, avoiding mislabeling or fraudulent species substitution in meat mixtures.

Despite similar genome sizes, a great variability in recombination rates is observed in mammals. We used antibodies against SYCP3, MLH1 and centromeres to compare crossover frequency, position along chromosome arms and the effect of crossover interference in spermatocytes of 4 species from the family Bovidae (Bos taurus, 2n = 60, tribe Bovini; Ovis aries, 2n = 54, Capra hircus, 2n = 60 and Ammotragus lervia, 2n = 58, tribe Caprini). Despite significant individual variability, our results also show significant differences in both recombination rates and the total length of autosomal synaptonemal complexes (SC) between cattle (47.53 MLH1 foci/cell, 244.59 µm) and members of the tribe Caprini (61.83 MLH1 foci, 296.19 µm) which can be explained by the length of time that has passed since their evolutionary divergence. Sheep displayed the highest number of MLH1 foci per cell and recombination density, although they have a lower diploid chromosome number caused by centric fusions corresponding to cattle chromosomes 1;3, 2;8 and 5;11. However, the proportion of MLH1 foci observed on the fused chromosomes in sheep (26.14%) was significantly lower than on the orthologous acrocentrics in cattle (27.6%) and goats (28.2%), and their distribution along the SC arms differed significantly. The reduced recombination rate in metacentrics is probably caused by interference acting across the centromere.

AbstractHuman–carnivore conflict is one of the major challenges in the management of populations of large carnivores. Concerns include the increasing human population; habitat loss as a result of degradation and fragmentation of forest; and livestock predation as a result of a lack of natural prey, leading to retaliatory killings of wild carnivores. Conflicts may be further aggravated by occasional attacks that result in injury and loss of human life. The level of consumption of prey species by a predator is a benchmark to evaluate the scale of this conflict. We used a newly developed DNA-based diet analysis to study the prey profile of common leopards Panthera pardus in Ayubia National Park, Pakistan. The results suggest that the common leopard is a generalist predator, subsisting mainly on domestic animals. Based on the frequency of occurrence of prey items in 57 faecal samples, the diet of the leopard is dominated by domestic goat Capra hircus (64.9%), followed by domestic dog Canis lupus familiaris (17.5%) and cow Bos taurus (12.3%). Domestic animals (goat, dog, cow, water buffalo Bubalus bubalis, horse Equus caballus and sheep Ovis aries) occurred in 54 (95%) of the 57 samples. We recommend a two-step strategy to mitigate this conflict: (1) introducing incentives for increased acceptance of leopards among local communities in the vicinity of the protected area and (2) increasing the availability of wild prey. We hope that the results of this study will contribute to the survival of the leopard in Pakistan.

Bearded Vulture

SummaryAlthough most Old World vulture species are declining or threatened in Asia and Africa, in Europe healthy vulture populations still exist. However, recent application of sanitary legislation that has greatly reduced the availability of animal carcasses is now a concern for conservationists. Until now, no studies have been undertaken to determine long-term dietary shifts in these species in Europe, but such studies are essential to optimising the resources invested in conservation and to anticipating the ecological needs of the target species. Here, we present a first attempt to examine the dietary variation in the Bearded Vulture Gypaetus barbatus from the late Pleistocene to the present day. Medium-size wild ungulates such as southern chamois Rupicapra pyrenaica, Spanish ibex Capra pyrenaica, red deer Cervus elaphus and roe deer Capreolus capreolus dominate the diet during the Pleistocene supporting the hypothesis that Bearded Vulture distribution was largely determined by the presence of such species. On the contrary, domestic species, such as sheep Ovis aries and goat Capra hircus, are the most common taxa in the diet in modern and historic periods. The actual dependence of the species on livestock, along with a restrictive sanitary legislation, threaten the conservation of this and other endangered avian scavengers in Europe. This new paleobiological conservation perspective confirms that efforts to establish a self-sustaining Bearded Vulture population should be enhanced by the widespread availability of medium-sized wild ungulates and by the presence of extensive and traditional grazing practices.

SummaryThe casein micelles of sheep (Ovis aries), goat (Capra hircus) and cow (Bos taurus) milks have been examined by electron microscopy. The ovine micelles were smaller than bovine micelles, most being below 80 nm diam. The caprine micelles were either large (c. 200 nm diam.), easily sedimented and electron-dense, or small (below 80 nm) and similar to the ovine micelles. Examination of the micelles using the freeze-etch technique showed, however, that they were all composed of subunits of similar dimensions (10–15 nm diam.).Electrophoresis of the caseins showed that there were differences between them, with the caprine casein containing a smaller proportion of its protein in the more mobile components. The mineral contents of the milks were also different, but these were apparently related to the different pH and casein contents of the milks. It is likely that the diiferences in micelle size distribution are determined by the physical and chemical properties of the casein components.
