Background: We present a study about helminth parasites in wolf (Canis lupus signatus) from Sierra de la Culebra, a protected area in the Northwest of Spain, where is the largest population of wolves of the Spanish territory and one of the largest in Western Europe. Materials and Methods: To this aim, 93 fecal samples were collected during May and June of 2013 using 33% zinc sulphate flotation technique and classified based on their morphology, color, structure and size. Results: Parasites were present in 66.67% of the samples and classified as Eucoleus aerophilus (50.54%), Strongyloides sp. (27%), Ancylostomidae gen. sp. (19.35%), Toxocara Canis (10.75%), Taeniidae gen. sp. (9.68%), Trichuris vulpis (9.68%) and Toxascaris leonina (2.15%). Their distributions were very heterogeneous with the highest prevalence being in Northwest Spain. These differences found can be attributed to local environmental factors (ambient temperature, humidity) as well as animal feeding and social behavior. Conclusion: A wide helminthofauna is observed in the studied wolves, similar to other studies carried out in Europe (Estonia, Finland, Italy, Latvia, Poland, Portugal, Spain and Sweden). In addition, this study constitutes the first description of the presence of Strongyloides sp. in Iberian wolf in Spain.

The Selkirk Rex is one of the four curly cats and is the latest in a long line of natural breeds. Naturally occurring cat breeds, unlike those that have been bred in captivity, appear without any human involvement.

Context. Wolf predation on livestock can cause economic hardship for livestock producers as well as reduce tolerance for wolves. Lethal control of wolves is often controversial; thus, development of effective non-lethal methods for reducing wolf–livestock conflict is important. Electrified fladry is a new tool that is similar to fladry (i.e. a barrier system that scares wolves), but electrified fladry also incorporates an electric shock designed to decrease the potential for wolves to habituate to the barriers. Aim. Evaluation of electrified fladry requires understanding of its effectiveness relative to fladry and the costs and benefits of applying it in the field. Methods. By using captive wolves, we compared the effectiveness of electrified fladry v. fladry for protecting a food resource during 2-week trials. We then performed a field trial with electrified fladry for managing wolves in Montana, USA. We measured livestock depredation and wolf activity on six treatment and six control pastures, calculated the cost of installation and maintenance, and surveyed all study participants about application of electrified fladry. Key results. We found electrified fladry 2–10 times more effective than fladry at protecting food in captivity and that hunger increased the likelihood of wolves testing fladry barriers. In field trials, we installed 14.0 km of EF systems in treatment pastures and detected wolves twice in control pastures but never in the treatment pastures. No livestock were killed by wolves in treatment or control pastures. A completed electrified fladry system cost $2303 for the first km and $2032 for each additional km, and required 31.8 person-hours per kilometre to install. We observed 18 failures (i.e. electrified system stopped working) during a total of 394 days of use. In total, 83% of ranchers who used fladry would continue to use it under certain conditions, indicating some psychological benefit to users. Conclusions and implications. The present study has demonstrated that electrified fladry offers superior protection compared with non-electrified fladry; however, further field tests are warranted to help determine whether benefits outweigh costs.

AbstractEighty-nine samples of grey wolf (Canis lupus L.) faeces were collected between 2002 and 2004 from two areas in the western Beskidy Mts (south Poland). Helminth eggs were observed in 56.2% of faeces examined. These included: Alaria alata (2.2%), taeniid eggs (11.2%), Toxocara canis (5.6%), Toxascaris leonina (1.1%), Eucoleus aerophilus (14.6%), Ancylostoma caninum (12.3%), Uncinaria stenocephala (37%) and unidentified roundworm eggs of the family Strongyloididae (1.1%). Eucoleus aerophilus is recorded for the first time from Poland. The results are compared with the helminth fauna of other wolf populations in Europe.

El objetivo del presente estudio fue determinar la prevalencia de parásitos intestinales y los factores de riesgo asociados con la transmisión zoonótica en perros con dueño de la localidad rural de Retes, distrito de Huaral (Lima, Perú). Se realizó un estudio descriptivo de corte transversal, donde se recolectaron muestras fecales de 47 perros y fueron procesadas mediante los métodos directo simple, flotación de Willis-Molloy y sedimentación rápida modificada por Lumbreras. Así mismo, se hizo la identificación morfométrica de las especies parasitarias. El análisis estadístico se realizó mediante análisis bivariado con distribución Chi cuadrado. La prevalencia de enteroparasitosis fue de 31.9%. Se halló Dipylidium caninum (12.8%), Toxocara canis (10.6%), Ancylostoma spp (4.3%), Cystoisospora canis (4.3%), Taenia spp (2.1%). El monoparasitismo fue de 76.7% , seguido de biparasitismo 13.4% entre helmintos y protozoarios. Se halló como único factor de riesgo asociado al parasitismo intestinal el lugar de alimentación (OR=7.11; X2=5.23; p=0.03). Los helmintos zoonóticos del perro D. caninum, T. canis y Ancylostoma spp, dada la prevalencia encontrada, podrían transmitirse fácilmente al ser humano pues se encuentran ocupando el mismo hábitat en la zona rural de Huaral.

Milk was obtained from an Arctic wolf which was captured on Axel Heiberg Island, Northwest Territories, in 1961 and held in captivity for 5 years before the collection of the sample, and from two huskies. The gross composition of the milks and the fatty acid constitution of the milk fats were determined.
