Summary This article reports a Przewalski's horse from the Kalamaili Nature Reserve (KNR) in China transported to our institute to determine the cause of death. The animal had been subjected to necropsy before being transported to our institute; the entire digestive tract was removed but not opened to reduce the possible loss of parasites. During examination, ascarids in the intestines and bots in the oral cavity and stomach were observed. The parasites were identified according to an…

Histopathological Study of Esophageal Infection with Gasterophilus pecorum (Diptera: Oestridae) in Persian Onager (Equus hemionus onager)
TLDR
This is the first survey of G. pecorum and histopathological study in the Persian onager esophagus in the world and it contains hyperemia, inflammatory cell infiltration, epithelial destruction, esophageal gland hyperplasia.
Intestinal parasites in Przewalski's horses (Equus ferus przewalskii): a field survey at the Hortobágy National Park, Hungary
TLDR
This was the first study involving this population, showing 100% prevalence of intestinal parasites and there is a higher prevalence of Triodontophorus serratus and Poteriostomum spp.
Gastrointestinal Parasitism in Przewalski Horses (Equus ferus przewalskii).
TLDR
Many similarities can be found between the Przewalski's horse populations and the domestic horses regarding their gastrointestinal parasite community, and it might be necessary to better correlate the parasitological findings of this subspecies with other animals that share the same habitat and ecosystem.
Gastrointestinal Parasite Community in a New Population of the Przewalski’s Horse (Equus Ferus Przewalskii) in the Orenburg State Reserve, Russia
TLDR
The aim of this work was to investigate the species composition of the intestinal parasite community and to monitor the dynamics of the parasite infection of the newly established Przewalski’s horse population.
The Effects of Seasonality and Group Size on Fecal Egg Counts in Wild Przewalski’s Horses (Equus Ferus Przewalskii, Poljakov, 1881) in The Chernobyl Exclusion Zone, Ukraine During 2014 – 2018
TLDR
Results obtained in this current study broaden the knowledge of gastrointestinal parasites in free-roaming Przewalski's horses under wild natural conditions by suggesting that this could be a result of parasite transmission between individuals and groups in places were animals aggregate around water sources or collective farms.
Metagenomic Analysis of Fecal Archaea, Bacteria, Eukaryota, and Virus in Przewalski's Horses Following Anthelmintic Treatment
TLDR
The COG and KEGG function analysis showed that the intestinal microbiota of Przewalski's horse mainly participated in the carbohydrate and amino acid metabolism, and anthelmintic treatment did not change their overall function; however, it displaced the population of the functional microbes involved in each function or pathway.

The Injury Caused by Myiasis of Gasterophilus in Horse
TLDR
The results showed that with the growth of age,larvas gradually migrate towards the end of the digestive tract, and no inverse movements were found and helped to better understand of the harm caused by Gasterophilus and strongly supported the follow-up monitoring and protection on Przewalski horses.
Gasterophilus pecorum and Habronema muscae in Persian onager (Equus hemionus onager), histopathology and parasitology survey
TLDR
Main histopathological observations were interruption of the mucosa, gastric wall thickening, prominent parakeratosis, and acanthosis in Persian onager.

Acute small intestinal obstruction associated with Parascaris equorum infection in young horses: 25 cases (1985–2004)
TLDR
The incidence of anthelmintic treatment within 24 h of the onset of colic in this study population (72%) was higher than that previously reported, and resistance of P. equorum to ivermectin recently reported in Ontario may be associated with increased ascarid burdens, predisposing horses to ascarids impaction.
Pathomorphological study on gastroduodenal ulceration in horses: localisation of lesions.
TLDR
It is confirmed that gastric ulcers are a common problem in horses and duodenal or oesophageal ulceration is rare (not a single case of the latter was found in this study).
