Intestinal parasites in Przewalski's horses (Equus ferus przewalskii): a field survey at the Hortobágy National Park, Hungary.

The Pentezug Wildhorse Reserve, located in the Hortobágy National Park, Hungary, has one of the biggest ex situ populations of Przewalski's horses and aims to preserve its landscape and to study this subspecies. Between September and November 2018, 79 faecal samples were collected from Przewalski's horses. The McMaster, Willis flotation, natural sedimentation and coproculture methods were applied to all the samples. Results showed an average level of 1287 eggs per gram (EPG), which is a high faecal egg-shedding level. All the samples were positive for strongyle-type eggs (100%). There were no statistical differences regarding the EPG values between different harems of the population. The same happened when considering sexes, ages, lactating status or when bachelors are compared with harem members. Cyathostominae were dominant, when compared to Strongylinae and Tricostrongylidae, and 15 different morphological infective third-stage larvae types and/or species belonging to the order Strongylida were identified. The subfamily Cyathostominae was prevalent in 100% of the horses. Strongylus vulgaris was the most prevalent strongylin (40.5%). Additionally, 27.8% were positive for Parascaris sp. and 2.5% showed Oxyuris equi in their faeces. This study revealed that there is a higher prevalence of Triodontophorus serratus and Poteriostomum spp. in juveniles. Horses with S. vulgaris showed lower levels of EPG. This was the first study involving this population, showing 100% prevalence of intestinal parasites.

Authors call attention with the demonstration of pictures of a few cases of their own to the significance of the ultrasound examination in cases of shoulder injuries. They stress that beside the demonstration of rotator cuff injuries the examination of the surrounding muscles and the labrum glenoidale should not be forgotten either. The modernization of the ultrasound devices, the improvement of the methods of examination and the obtaining of the necessary practice ensure a more and more important place to echography in the diagnosis of traumas of the motion organs.
