We investigated infections with Gasterophilus spp. in three equids within the Kalamaili Nature Reserve (northern China). We conducted necropsies on 6 Przewalski's horses (Equus ferus przewalskii) and 6 Mongolian wild asses (Equus hemionus) and administered ivermectin to 10 overwintering domestic horses to expel parasites during winter periods. All 22 equids studied (100%) were infested with Gas...

BACKGROUND: Gastric ulcer is one of the most common diseases in racehorses. Colic, weight loss and poor performance are some of the clinical signs. The second and third larval stages of the bot fly Gasterophilus spp live in the stomach of the horse. This parasite is often found in large numbers of horses in all of the countries. OBJECTIVES: The a...

Thirty-five Burchell's zebra, Equus burchelli, were shot for arthropod parasite recovery during the period November 1978-January 1982 in the Kruger National Park. Six species of gasterophilid larvae, 2 species of oestrid larvae, 2 louse species and 7 ixodid tick species were recovered. The distribution of the Gasterophilus spp. larvae within the gastrointestinal tract and their seasonal prevale...

Introduction Parasites live in a host from which they obtain food and protection. They may harm but usually do not benefit the host. The word “parasite” is derived from the Latin and Greek languages meaning, in general, “one who eats at the table of another.” It is said that a “good” parasite does not overtly harm or kill its host. It is theoretically possible that a more benign parasite (e.g. ...

The arthropod parasite burdens of 14 Cape mountain zebra (Equus zebra zebra), shot for survey purposes in the Mountain Zebra National Park in the eastern Cape Province, were determined. Three species of Gasterophilus larvae and 9 ixodid tick species were recovered. Larvae of Gasterophilus pecorum were the most numerous of the fly larvae recovered and Margaropus winthemi was the most abundant ti...

Twelve Hartmann's mountain zebra, Equus zebra hartmannae, were shot for arthropod parasite recovery during the period June 1980-June 1981 on a farm in the Khomas Hochland region of South West Africa/Namibia. Four species of Gasterophilus larvae, 1 species of Rhinoestrus larvae and 3 ixodid tick species were recovered. The seasonal prevalence of the Gasterophilus species larvae and of Rhipicepha...

Gasterophilosis is a myiasis related with gastric ulcers in equids and even colics. A serological survey to assess the presence of IgG antibodies against Gasterophilus spp. in horses from an oceanic climate area was conducted. A total of 672 blood samples were analyzed by an enzyme-linked immunosorbent assay (ELISA) and excretory/secretory antigens from G. intestinalis second-instar larvae. Res...

Dental care is an integral part of equine veterinary practice. The objectives of this cross sectional study were to describe the prevalence of dental disorders in an abattoir population of horses, and to compare oral examination of intact and bisected heads. Heads from 40 horses, 19 males and 21 females, were examined and divided into immature, adult or older horses based on dental age. Older h...
