Topic:Disease Treatment
Disease treatment in horses encompasses a range of medical interventions and management strategies aimed at addressing various health conditions affecting equine species. These treatments can include pharmacological approaches, such as the administration of antibiotics, anti-inflammatory drugs, and antiparasitic medications, as well as non-pharmacological methods like physical therapy, dietary adjustments, and surgical procedures. The selection of appropriate treatments depends on the specific disease, its severity, and the individual needs of the horse. This topic brings together peer-reviewed research studies and scholarly articles that explore the efficacy, safety, and advancements in therapeutic options for equine diseases, providing insights into best practices and emerging trends in equine veterinary medicine.
Studies with inactivated equine influenza vaccine. 1. Serological responses of ponies to graded doses of vaccine. Serological responses to three bivalent aqueous equine influenza vaccines of different potency and an adjuvanted bivalent vaccine containing inactivated A/equine/Prague/56 (H7N7) and A/equine/Miami/63 (H3N8) viruses, were examined in seronegative ponies. Potencies of the vaccines, measured by single-radial-diffusion tests, ranged from 4 to 56 micrograms of haemagglutinin (HA) antigen activity/virus strain per dose. Serological responses to vaccination were examined by haemagglutination-inhibition (HI) and single-radial-haemolysis (SRH) tests. Four weeks after a primary dose, HI responses to bo...
Influence of acepromazine maleate on the equine haematocrit. The effect of acepromazine maleate (ACP) on the equine venous haematocrit and total plasma protein concentration was studied in six clinically normal horses. Total plasma protein concentration was not appreciably influenced by ACP. However, the haematocrit decreased with the duration, but not the degree, of the decrease being dose-related. Mean haematocrit values returned to control levels by 12 h after 0.05 mg ACP/kg body weight and 21 h after 0.15 mg ACP/kg body weight.
Measurement of tracheal mucous transport rate in the horse. Tracheal mucous transport rates were measured in 12 nonanesthetized horses after an intratracheal injection of 99mtechnetium-sulfur colloid. The transport rate of the subsequent bolus of radioactivity was determined, using a portable scaler rate meter fitted with a high-energy gamma-scintillation probe. A gamma-scintillation camera was used to verify bolus form and movement in 1 horse. The mean tracheal mucous transport rate was 1.66 +/- 0.24 cm/min.
Study of equine histoplasmosis farciminosi and characterization of Histoplasma farciminosum. A detailed clinical and mycological study of horse infections with Histoplasma farciminosum was conducted for the first time in the Middle East. The disease seems to prevail in endemic form in the region. In all of the cases studied the infection involved only the cutaneous lymphatics and skin tissue with extension to the regional draining lymph glands. The disease seems to impose serious economic impact in the infected areas. Full description and thorough characterization of both the mycelial form and the yeast phase of the causative fungus were made.
Aggregation of equine platelets by PAF (platelet-activating factor). Platelet-activating factor (PAF), a lipid released as a result of immediate allergic reactions from basophils and mast cells as well as by a variety of other cell types and stimuli, is one of the most potent platelet agonists and hypotensive agents known. Equine platelets stimulated over a wide range of PAF concentrations aggregated in a time- and dose-dependent manner. Maximum aggregation was observed at concentrations of PAF as low as 3.58 x 10(-14) M with platelet-rich plasma (PRP) and 3.58 x 10(-16) M with washed platelets. Furthermore, the aggregation observed did not appear to be breed-d...
Efficacy of ivermectin against Onchocerca cervicalis microfilarial dermatitis in horses. Forty horses having microfilariae of Onchocerca cervicalis in association with dermatitis, alopecia, and pruritus on the ventral midline were given a single IM injection of 0.2 mg of ivermectin/kg of body weight (June to August 1981). Microfilarial counts in the 40 horses ranged from 18 to 42,446 microfilariae/skin snip on the day of treatment, and histopathologic examination of these skin sections indicated a chronic eosinophilic dermatitis. Numerous microfilariae were in the dermis, but there was no consistent relationship between the presence of microfilariae and the severity of the inflamm...
Complications associated with immunotherapy of equine phycomycosis. Five horses with pythiosis of the limbs were treated unsuccessfully by surgery or topical application of amphotericin B, or both. Follow-up immunotherapy resulted in 1 horse responding favorably. Three horses were cured of the fungal infection but developed osteitis or deep-seated laminitis, which necessitated their destruction. The remaining horse, which had severe anemia, died before the course of vaccination was completed.
Evaluation of mebendazole used concurrently with piperazine monohydrochloride in horses. Forty horses from a herd known to have benzimidazole-resistant small strongyles were treated with mebendazole (8.8 mg/kg) or combinations of mebendazole and piperazine monohydrochloride (25, 40, or 55 mg of piperazine base/kg). Pretreatment and 7-day posttreatment fecal examinations were done. Fecal cultures and strongyle egg per gram (epg) counts, and in vitro testing for benzimidazole resistance were performed. Results of fecal examinations prior to treatment were similar in all horses, and results of testing were positive for benzimidazole resistance. Horses treated with mebendazole and pip...
Effect of spasmolytic analgesic drugs on the motility patterns of the equine small intestine. The effect of acepromazine, Buscopan (Crown Chemicals), pethidine and methadone was evaluated in ponies prepared with Thiry-Vella (T-V) loops. Motility was assessed by electrophysiological means (bipolar electrodes and strain gauge transducers) and by the passage through the T-V loop of a fluid test meal. Results were obtained from 26 experiments in three ponies and compared with six control experiments, in which saline had been administered to the same ponies. Each pony acted as its own control in each experiment and pre and post treatment values for slow wave frequency, spiking activity, del...
Effect of iron-saccharin injections of Finnish horses. In four training stables five trotter horses of the Finnish coldblooded breed and seven warmblooded trotters were treated with a ferrissaccharin preparation (Hippiron, Hausmann) intravenously. A short increase in heart frequency after the injection was noted. The cold solution injections, less than + 15 degrees C, may cause dangerous reactions. All horses showed an enhanced appetite, a substantially livier habitus after treatment.
Use of schizont and piroplasm antigens of Babesia equi in the indirect fluorescent antibody and complement fixation tests. Eight ponies infected with Babesia equi were investigated for their serological response to B. equi schizont and piroplasm antigen with the indirect fluorescent antibody test (IFAT) and complement fixation test (CFT). Piroplasm antigen was prepared from an infected splenectomized pony, while schizont antigen was produced from cultured lymphoid cells which contained B. equi macroschizonts. The IFAT detected a rise in antibody titres to schizont antigen as well as to piroplasm antigen, but differences were obtained in the duration of antibody detection. Significant antibody titres to piroplasm a...
[Genetic research in the field of reproductive pathology and genetic prophylaxis in agricultural animals in the Socialist Republic of Romania]. The paper presents the results of some genetic studies accomplished in Romania in the field of pathology of reproduction in domestic animals (pseudohermaphroditism in horses, testicular hypoplasia in he-goats, intersexuality in pigs, freemartinism and genital infantilism in cattle). Also, the use of the cytogenetic test in genetic prophylaxis in pigs and cattle was shown. In addition, the methods for detecting genitors with undesirable genes were devised and perspectives for the development of hereditary hygiene discussed.
Caecal rupture in parturient mares. The pathology of 4 cases of caecal rupture in foaling mares is described. One of these animals died suddenly, probably when rupture occurred, and 3 survived for 5 to 8 h and died from acute peritonitis.
The pathogenesis of this type of injury is discussed and it is suggested that rupture may arise from the pressure of a foetal hind foot against the caecum when distended by local tympany.
