Topic:Veterinary Medicine

Veterinary medicine for horses encompasses the study and application of medical practices to diagnose, treat, and prevent diseases in equine species. This field involves a comprehensive understanding of equine anatomy, physiology, pathology, and pharmacology. Veterinary practitioners employ a range of diagnostic tools and therapeutic interventions to address health issues in horses, including lameness, gastrointestinal disorders, respiratory conditions, and infectious diseases. Preventative care, such as vaccination and deworming programs, is also a significant aspect of equine veterinary medicine. This page gathers peer-reviewed research studies and scholarly articles that explore various aspects of veterinary medicine as it pertains to horses, including advancements in diagnostic techniques, treatment protocols, and preventive health strategies.
Induction of parturition in mares: effect on passive transfer of immunity to foals.
Journal of the American Veterinary Medical Association    February 1, 1983   Volume 182, Issue 3 255-257 
Townsend HG, Tabel H, Bristol FM.Parturition was induced in 11 mares, using a synthetic prostaglandin. Eight mares, not treated, were used as controls. There was no significant difference between the serum immunoglobulin G (IgG) concentrations of the treated and control mares. The concentration of IgG in the colostrum of treated mares compared favorably with that reported for naturally foaling mares. Four foals from treated mares died or were euthanatized because of weakness during the 1st 24 hours after birth. The mean IgG concentration in the surviving foals from treated mares at 24 to 36 hours of age was 1,561 mg/100 ml, w...
[Contribution to the parasitic fauna of the GDR (German Democratic Republic). 7. Occurrence of Gasterophilus larvae (Diptera: Gasterophilidae) in horses].
Angewandte Parasitologie    February 1, 1983   Volume 24, Issue 1 39-49 
Ribbeck R, Heide H, Schicht W, Hiepe T.Observations were carried out from May 1977 to May 1980 on occurrence, fauna, and seasonal dynamics of Gasterophilus spp. in 2,539 horses for butchering from all districts of the German Democratic Republic and also in 79 horses after control against gasterophilosis. 99.98% of the 13,742 second and third instar larvae of horses for butchering were Gasterophilus intestinalis, only 0.02% Gasterophilus nasalis. Out of 7,765 larvae passed after control measures Gasterophilus intestinalis dominated with more than 96%. Only in four districts of the German Democratic Republic Gasterophilus nasalis was...
Difference in sizes of human compared to murine alpha-subunits of the glycoprotein hormones arises by four-codon gene deletion or insertion.
Endocrinology    February 1, 1983   Volume 112, Issue 2 482-485 doi: 10.1210/endo-112-2-482
Chin WW, Maizel JV, Habener JF.The sizes of the human and subhuman alpha-subunits of the glycoprotein hormones differ by four amino acids (hCG alpha, 92 amino acids; murine, equine, bovine, and ovine alpha, 96 amino acids). The shortening of the human alpha-subunit has been attributed to posttranslational proteolysis. We have recently determined the nucleotide sequences of the mRNAs encoding the precursors of the alpha-subunit of mouse TSH and rat gonadotropins using recombinant DNA techniques. In this report, we have compared these nucleotide sequences and their deduced amino acid sequences with those of the pre- alpha-sub...

Critical tests in equids with fenbendazole alone or combined with piperazine: particular reference to activity on benzimidazole-resistant small strongyles.
Veterinary parasitology    February 1, 1983   Volume 12, Issue 1 91-98 doi: 10.1016/0304-4017(83)90092-4
Lyons ET, Tolliver SC, Drudge JH.Seven critical tests in equids were conducted with single doses of fenbendazole (5 mg kg-1) alone (Panacur--American Hoechst, Somerville, NJ); (2 tests with paste and 1 with suspension formulation) or in combination with piperazine (American Hoechst); (40 mg base kg-1); (4 tests with paste formulation). The main purpose of the tests was evaluation of activity against benzimidazole-resistant small strongyles (Cyathostomum catinatum, Cyathostomum coronatum, Cylicocyclus nassatus, Cylicostephanus goldi, and Cylicostephanus longibursatus). Natural infections of 2 populations of benzimidazole-resis...

Clostridium perfringens cellulitis and immune-mediated hemolytic anemia in a horse.
Journal of the American Veterinary Medical Association    February 1, 1983   Volume 182, Issue 3 251-254 
Reef VB.A 10-year-old Quarter Horse mare was referred for evaluation and treatment of a large pectoral skin slough and hemoglobinuria. The skin slough was secondary to Clostridium perfringens cellulitis and associated gas gangrene. Cold hemagglutinin disease was diagnosed and was suspected to be secondary to C perfringens septicemia. The autoimmune hemolytic anemia, severe intravascular hemolysis, and hemoglobinuria were treated with dexamethasone and hydrocortisone. The infection was treated with 20 X 10(6) units of sodium penicillin, IV, 4 times daily, and the wound was debrided. When the mare relap...
Sodium retention and cortisol (hydrocortisone) suppression caused by dexamethasone and triamcinolone in equids.
American journal of veterinary research    February 1, 1983   Volume 44, Issue 2 280-283 
Slone DE, Purohit RC, Ganjam VK, Lowe JL.Three ponies and 1 horse were bilaterally adrenalectomized (BADX). The initial hypoadrenal episode after BADX was reversed with 20 mg of dexamethasone (DXM) IM (n = 2) or 20 mg of triamcinolone (TMC) IM (n = 2). Nine hypoadrenal crises were reversed with 20 mg of DXM given IM (n = 4) or 20 mg of TMC given IM (n = 5). Sodium and chloride retention and potassium excretion were documented based on changes in serum electrolytes and urinary excretion. Eight intact adult horses were randomly assigned to 2 groups to study the effects of a single IM injection of DXM (0.044 mg/kg of body weight) or TMC...
The activity of closantel as an equine antiparasitic agent.
Veterinary parasitology    February 1, 1983   Volume 12, Issue 1 71-77 doi: 10.1016/0304-4017(83)90090-0
Guerrero J, Michael BF, Rohovsky MW, Campbell BP.Eighteen pony foals were experimentally infected with 500 third stage larvae of Strongylus vulgaris at 2 weeks, and at 2, 4, 6 and 8 months after birth. For the duration of the study, all foals were kept in the same pasture with their mothers to allow natural infection with other parasites by exposure to a contaminated environment. Twelve of the foals were utilized in groups of 3 and treated orally five times at two month intervals starting at one month of age with closantel at doses of 5, 10, 20 or 40 mg kg-1. Ten months after birth the foals were necropsied to determine the parasitic burdens...

Equine complement activation as a mechanism for equine neutrophil migration in Onchocerca cervicalis infections.
Clinical immunology and immunopathology    February 1, 1983   Volume 26, Issue 2 277-286 doi: 10.1016/0090-1229(83)90146-0
Camp CJ, Leid HW.Extracts of Onchocerca cervicalis, an equine parasite, were incubated with radiolabeled equine neutrophils and neutrophil migration was assessed for factors derived from the parasite itself or for host-derived factors after incubation of these same parasite extracts with equine serum. No stimulus for cell migration was observed in saline extracts of adult worms, uterine microfilariae, or skin microfilariae at any dosage tested. However, after incubation of saline extracts with fresh normal equine sera a marked stimulus for neutrophil migration was observed. Ablation of this biologic activity w...

Pathogenic bacteria and fungi associated with extraocular disease in the horse.
Journal of the American Veterinary Medical Association    February 1, 1983   Volume 182, Issue 3 241-242 
McLaughlin SA, Brightman AH, Helper LC, Manning JP, Tomes JE.In 123 cases of external ocular disease in the horse, pathogenic microorganisms isolated with greatest frequency were Streptococcus sp (43.9%), Staphylococcus sp (24.2%), and Pseudomonas sp (13.8%). Fungi were isolated in 4.8% of the cases. In vitro testing showed that most of the Streptococcus sp isolants were sensitive to ampicillin, cephalothin, and carbenicillin. Most of the Staphylococcus sp isolants were sensitive to gentamicin, cephalothin, and bacitracin. Most of the Pseudomonas sp isolants were sensitive to polymyxin B and gentamicin.
Marker characteristics of Venezuelan encephalitis virus strains isolated before and after epidemics and equine epizootics in Middle America.
American journal of epidemiology    February 1, 1983   Volume 117, Issue 2 201-212 doi: 10.1093/oxfordjournals.aje.a113531
Wiebe ME, Scherer WF, Peick WJ.Ninety-four strains of Venezuelan encephalitis (VE) virus isolated from sentinel hamsters exposed in the Middle American countries of Mexico, Guatemala, Belize, and Honduras were examined for the presence of virions with marker characteristics of strains that cause large epidemics and equine epizootics. Thirty-four strains came from before and 60 strains came from after the Middle American epidemics and equine epizootics of 1966 and 1969-1972. Twenty-three virion clones that resembled epizootic strains by hydroxylapatite chromatography and Vero monkey kidney cell plaque size determinations wer...

Pathologic changes in 3-methylindole-induced equine bronchiolitis.
The American journal of pathology    February 1, 1983   Volume 110, Issue 2 209-218 
Turk MA, Breeze RG, Gallina AM.The pathologic features of bronchiolitis were studied in horses and ponies from 30 minutes to 27 days after an oral dose of 3-methylindole (3MI). From 30 minutes to 3 hours, lesions were limited to nonciliated bronchiolar epithelial (Clara) cells, which lost apical caps and cytoplasmic granules and had dilated smooth endoplasmic reticulum (SER). At 12 hours, necrotic Clara cells were exfoliated; degeneration and necrosis were evident, in bronchiolar ciliated cells. Rare epithelial cells with hyperplastic SER appeared on the denuded basal lamina at 24 hours. Inflammatory cells, epithelia, fibro...
Studies on the strongyle egg output of horses after treatment with oxfendazole (Synanthic vet. Syntex).
Nordisk veterinaermedicin    February 1, 1983   Volume 35, Issue 2 69-73 
Nilsson O, Klingborn B.The effect of oxfendazole (Synanthic vet. Syntex) on the strongyle egg output of naturally infected horses was evaluated. It was demonstrated that the compound, administered orally as an 18,5% paste or as 6,48% pellets mixed in feed (46.3 grams per 300 kg bodyweight) at a dose-rate of 10 mg per kg bodyweight, markedly reduced the strongyle egg output over a 10 week period. As this period to egg reappearance is considerably longer than for most other anthelmintics at recommended dose levels, oxfendazole may be considered a valuable compound for the control of strongylosis in horses.

Investigations into the biology of three ‘phycomycotic’ agents pathogenic for horses in Australia.
Mycopathologia    January 17, 1983   Volume 81, Issue 1 23-28 doi: 10.1007/BF00443905
Miller RI.Although 'phycomycosis' is a common disease of horses in northern Australia little is known about the causative fungi. In this paper the laboratory methods for diagnosis are described. These revealed 38 cases caused by Pythium sp. (Hyphomyces destruens), 6 cases caused by Basidiobolus haptosporus and 2 caused by Conidiobolus coronatus. Laboratory studies on the chemotatic behaviour of zoospores of Pythium sp. showed that they were strongly attracted to both animal hairs and plant tissue. Because of this behaviour a simple baiting method using human hair was used to trap the fungus from water s...
[A pony with “false” colic].
Tijdschrift voor diergeneeskunde    January 15, 1983   Volume 108, Issue 2 67-69 
van Wuijckhuise-Sjouke LA.Report on the case of a pony with colic submitted a to the department of internal medicine. However, the animal was found to be affected with dilatation of the oesophagus which had given rise to acute pleurisy resulting from rupture of the wall of the oesophagus. The diagnosis was established after death.

Effects of common radioiodination procedures on the binding of glycoproteins to immobilized lectins.
Biochemical and biophysical research communications    January 14, 1983   Volume 110, Issue 1 103-107 doi: 10.1016/0006-291x(83)91266-4
Montelaro RC, West M, Ivey M.Representative glycoproteins including fetuin, protein A, ovalbumin, alpha 1 acid glycoprotein, and the major glycoprotein of equine infectious anemia virus were labelled with 125I by the chloramine-T or Bolton-Hunter procedure and their binding to immobilized Con A or lentil lectin compared to untreated samples of each glycoprotein. Glycoprotein modification was no greater than one substituted residue per protein molecule. Yet the radioiodinated glycoproteins typically displayed only 0-50% of the lectin binding observed with untreated samples. These results indicate that lectin glycoprotein b...
