Globulins are a group of proteins found in the blood plasma of horses, playing a significant role in various physiological processes, including immune function and nutrient transport. These proteins are categorized into different types, such as alpha, beta, and gamma globulins, each with distinct functions. Gamma globulins primarily consist of immunoglobulins, which are antibodies critical for the horse's immune response. The concentration of globulins in the blood can provide valuable information about a horse’s health status, as alterations may indicate conditions such as infections, liver dysfunction, or immune disorders. This page compiles peer-reviewed research studies and scholarly articles that explore the structure, function, and clinical relevance of globulins in equine health.
Mirck MH, Franken P.Experimental infections using 600,000 infective larvae of Strongyloides westeri were carried out in seven worm-free Shetland ponies, four foals and thee yearlings. In the foals, the prepatent period varied from ten to fourteen days, the patent period ranging from forty-three to eighty-three days. Within approximately two months after infection, a decrease in the concentration of haemoglobin and an increase in the beta-globulin fraction of the protein pattern of the serum, practically coinciding with the maximum S. westeri faecal egg counts, were recorded. In the yearlings, the prepatent period...
Kristensen F, Firth EC.Using agarose as a supporting matrix, electrophoresis was conducted on 50 serum samples and 20 cerebrospinal fluid samples from clinically normal horses (n = 50) of various ages and breeds. The technique was shown to be reliable. A positive correlation between age and gamma-globulin concentration was found in young horses. Features of the electrophoretograms of serum and cerebrospinal fluid samples are discussed, and a nomenclature based on Rf values is proposed.
Liberg P, Magnusson LE, Schougaard H.Synovial fluid and blood were collected from 18 clinically healthy brood mares in resting conidition. The following parameters were analysed: total leucocytes, glucose, alkaline phosphatase (AP), lactate dehydrogenase (LDH), total protein, albumin, total globulin, albumin/globulin ratio and electrophoretic protein picture. The serum/synovia ratios were calculated for all parameters. It was considered to be of greater diagnostic value to compare these serum/synovia ratios rather than to look at the individual concentrations in synovia. The results obtained did not materially differ from those i...
Kingsbury ET, Gaunt SN.The possible existence of multiple forms in the whey proteins of mare's milk was investigated. When individual milk samples from over 300 animals of various breeds were examined, four forms of an undescribed whey protein could be observed. Based on chemical properties and electrophoretic behavior, this protein has been identified tentatively as Whey1 (Wh1). A single case of heterogeneity in mare's alpha-lactalbumin also was observed. Previously described variation in beta-lactoglobulin could not be confirmed. The results of this study provide further evidence of the widespread, perhaps univers...
Carroll EJ, Lasmanis J, Schalm OW.A method is described for production of an equine anti-bovine leukocyte serum (EABLS). Leukocytes were harvested from the milk of cow's udders which had been irritated with endotoxin. The washed leukocytes as antigens were administered to 2 horses in a series of subcutaneous and intravenous injections. There was a variably progressive increase in total serum proteins and a decrease in albumin/blobulin ratios, but the most pronounced change was an increase in beta2-globulins. Accompanying these changes was an increase in the number of precipitin lines as shown by Ouchterlony analysis. Four old ...
Phillips AW, Woodrooffe JG, Courtenay JS, Whitaker AM, Thomas D, Woiwod AJ.Antibodies to cultured human lymphoblasts were raised in horses using a schedule employing both subcutaneous and intravenous routes of injection. Plasma from groups of horses was pooled and the IgG prepared from each pool was tested extensively for safety and immunosuppressive efficacy in vitro and in vivo. On the basis of the results of skin grafting in monkeys, only globulins derived from the first main bleeds were blended to produce a bulk for clinical use. One early pool of globulin was discarded because when undiluted, it was lethal in monkeys by the intravenous route, and another pool wa...
Frerichs WM, Holbrook AA, Allen PC.Twenty Shetland ponies, 6 to 7 months old, were naturally infected with gastrointestinal nematodes and stomach bots. The ponies were allotted to 2 groups of 10 and were maintained on separate similar pastures that were free of infective larvae at the beginning of the study. The ponies in 1 group were treated monthly for 17 months with a therapeutic dose of a thiabendazole and piperazine mixture; those in the other group were not treated. During the 3rd and 5th months of the experiment, the ponies in the treated group were also given therapeutic doses of dichlorvos to remove bots. Various physi...
Duncan JL, Pirie HM.The clinical signs, pathology and clinical pathology associated with single experimental infections of Strongylus vulgaris in worm-free pony foals are described. The major clinical signs which became apparent in the infected foals during the first three weeks were pyrexia, anorexia, dullness and abdominal pain. Within the first two weeks of infection lesions were confined to the intestine and terminal branches of the intestinal arteries and consisted of mucosal, submucosal and serosal haemorrhage together with arteritis of submucosal and serosal arteries and also a marked inflammatory reaction...
James K, Pullar DM, Morton JB, Dalton RG, Nolan B, Woodruff MF.Methods are described for the intravenous administration of equine antilymphocytic globulin (ALG) to renal transplant recipients. The development of circulating antibodies to the equine IgG has been investigated using primary and secondary immunological procedures. The need for primary immunoassay procedures to assess both the immune response and induction of tolerance to equine IgG in ALG treated patients is extensively discussed.
Ameniya H, Kashiwagi N, Putnam CW, Starzl TE.In the sera of ten normal humans and twenty-eight candidates for organ transplantation, the passive haemagglutination test detected a 50% incidence of preformed antibodies of low titre directed against horse serum. Such antibodies were also found to cross react with goat or rabbit sera in most instances. Seventeen of the organ recipients were later studied after the institution of treatment with horse antihuman-lymphocyte globulin (ALG). The incidence of anti-horse-serum antibodies rose to 100%. At the same time, an increased activity against goat serum developed; cross-reactions against rabbi...
Ek N.A method for the rapid electrophoresis on a cellulose acetate membrane of serum proteins from horses, sheep and pigs is discussed. The various main globulin fractions in the serum of these animals were experimentally identified. Normal values for the percentage composition of serum from normal horses, sheep and pigs were calculated. In the horse there was great individual variation in the shape of the β-fraction, assumed to be due to different transferrin types. The mean value for β-globulin of 19.5 % in the horse was higher than for the other two species. The albumin percentage was highest ...
Irfan M.The normal electrophoretic pattern and values for total and differential serum proteins have been determined for 100 cattle, 70 horses, 15 dogs, and 24 rabbits. Comparative studies were also made on 10 pigs, 10 goats, 10 sheep and 15 domestic fowls. The mean total serum protein for normal cattle was 7·16 g.%. The individual protein fractions were: albumen 43·1; alpha-globulin 110; beta-globulin 12·0; gamma-globulin 33·9%.
The mean total serum protein for normal horses was 7·3 g.%. The individual protein fractions were: albumen 33·5; globulins: alpha-1 15·0, alpha-2 16·0, beta-globul...
Rogers HJ.Under a variety of conditions of concentration, Eh, and pH, horse anti- serum and normal horse serum exerted similar bacteriostatic effects against Type A. Ferric iron abolished the bacteriostatic effect when added during the first 2 hours of incubation at Eh+60 mV. Ferrous iron abolished the bacteriostatic effect when added after 3 hours. Ferric iron abolished the bacteriostatic effect at—140 mV. A mixture consisting of horse β- and γ-globulins together with human transferrin exerted a bacteriostatic effect similar to that of whole serum. This system responded in the same way as whole se...
Böttiger LE.Erythrocyte sedimentation rate, total protein and fibrinogen, electrophoretic protein pattern, and total serum protein-bound carbohydrates have been determined in a number of domestic animals and compared to human values. The striking finding is that although the E.S.R. varies widely between various species, the fibrinogen content is of the same order of magnitude in all. The horse, which shows a very high E.S.R., has a well marked beta-globulin fraction as an outstanding feature, a finding that should be further studied. Blutsenkungsgeschwindigkeit, Gesamteiweiss und Fibrinogen, elektroforeti...
Lindner A.Several clinical chemical blood variables were compared, in order to evaluate the differences between Na heparinized plasma and serum samples. Samples from 45 healthy horses were used. No differences between the two sample substrates were found for aspartate aminotransferase, lactate dehydrogenase, lactate dehydrogenase-isoenzymes, creatine kinase, alkaline phosphatase, bilirubin, cholesterol, urea, total protein, alpha-globulin, gamma-globulin, albumin, calcium (Ca), phosphate (P), sodium (Na) and potassium (K). gamma-Glutamyltransferase and beta-globulin were significantly higher in heparini...

Gossett KA, French DD.Anion gap [AG = (Na + K) - (Cl + HCO3)] was determined in Quarter Horses: 10 clinically normal foals 0.5 to 3 days, 2 to 3 weeks, and 5 to 7 weeks of age; 10 yearlings; and ten 2-year-olds. Mean AG (+/- 1 SD) were 12.8 +/- 3.3, 15.2 +/- 2.9, 14.0 +/- 1.6, 12.3 +/- 1.8, and 10.4 +/- 1.2 mEq/L, respectively. The 4 to 5 mEq/L higher AG in 2- to 7-week-old foals, when compared with that in 2-year-old horses, can be explained in part by hyperphosphatemia (2 mEq/L) and lower calcium values (0.4 mEq/L). Decreased globulin concentrations may also contribute to the higher AG. The AG can be useful in th...

Lee HF, Lee JD, Lee YC.In course of immunizing horses with snake venoms, tetanus and diphtheria toxoids, a new serum component, T-globulin, was formed and migrated between the beta- and gamma-globulins. The T-globulin content was parallel with the antibody titre after the middle course of immunization. There were many components in snake antivenin and T-globulin was composed of most of those components. The components of diphtheria T-globulin were the same as those of crude antitoxin and tetanus T-globulin except one precipitin.
Sato T, Oda K, Kubo M.Hematological and biochemical parameters in five Thoroughbred foals during the first six months of life are reported. The samples were analyzed for red blood cell, packed cell volume, hemoglobin, platelet, white blood cell, absolute number for leukocytes, and erythrocyte fragility and serum calcium, inorganic phosphorus, sodium, potassium, chloride, magnesium, alkaline phosphatase, icterus index unit, bilirubin, blood urea nitrogen, nonprotein nitrogen, blood glucose, lacticdehydrogenase, glutamic pyruvic transaminase, glutamic oxalacetic transaminase, total protein, albumin, globulin, and A/G...

Daden R, Chbihi S, Zarhouni FZ, Chakir J, Piro M, Achaaban MR, Ouassat M, El Allali K.This article presents data on the effect of plasmapheresis on clinical, haematological and biochemical parameters in horses following exercise and after a plasmapheresis session. This blood filtration technique was realised on six jumping horses (plasmapheresis group) that underwent three consecutive days of graded physical exercise. The control group (n = 6) went through the same exercise but was not subjected to the plasmapheresis session. Blood was sampled before and after each exercise, also at the beginning and the end of plasmapheresis session. The presented data was obtained by measur...
Bailey M, Kent J, Martin SC, Lloyd S, Soulsby EJ.The concentrations of serum proteins (beta 1, beta 2, gamma, alpha 1, alpha 2 globulins and albumin) and absolute numbers of eosinophils, neutrophils and lymphocytes were examined in 64 naturally infected horses and ponies in which the number of larvae of Strongylus vulgaris in the cranial mesenteric artery and the severity of the lesion of verminous arteritis could be determined. The horses were grouped according to the number of larvae found and the severity of the arteritis. The results demonstrated that, although some significant deviation from a random distribution occurred in certain of ...
Câmara ACL, de Sousa Argenta VL, de Moraes DDA, Fonseca EF, Fino TCM, Paludo GR, Soto-Blanco B.Determining the prognosis of poisoning by plants containing pyrrolizidine alkaloids is usually challenging. This study aimed to identify important prognostic parameters that can determine the severity of spontaneous poisoning by in horses. Blood samples from 42 horses spontaneously poisoned by oats contaminated with seeds were evaluated. Complete blood counts (CBC) and serum biochemical tests [urea, creatinine, total protein, albumin, total and direct bilirubin concentrations, aspartate aminotransferase (AST), γ-glutamyl transferase (GGT), and creatine kinase (CK) activities] were performed...
Otani S, Arimitsu Y, Akama K.Antileptospiral sera from hyperimmunized horses were fractionated by gel filtration on Sephadex G-200 or by starch block electrophoresis. The fractions were examined quantitatively for leptospiricidal, agglutinating and complement fixing activities. The leptospiricidal activity was higher in the 78 globulin fraction than in the 19S globulin fraction, while the agglutinating activity was shared by both the fractions being higher in the 19S fraction. Complement fixing activity was found evenly in both the fractions. Leptospiricidal and complement fixing activities were higher in gamma-globulin t...
Abdou NI, Amare M, Sagawa A, Abdou NL.To understand the mechanism by which deaggregated horse anti-human thymocyte globulin (dATG) fails to induce untoward immunological reactions in man, three patients who received ATG and two patients who received dATG were studied for evidence of sensitization or tolerance to the foreign globulin. The ATG but not the dATG recipients developed allergic or serum sickness reactions; antihorse serum antibody could be detected in their serum and their blood cells proliferated in vitro in the presence of horse serum and secreted antihorse serum antibodies (P less than 0.001). Tolerance of the dATG re...

Borgsteede FH, Bruin G, Smolders EA.In 1983 and 1984 the effect of a deworming scheme, in which horses were treated at turn out and 4 and 8 weeks later, on the egg output, larval differentiation, weight gain, herbage infestation and in 1984, the percentages of some serum proteins were tested. In 1983 the experiment was done with 42 mares, 54 two year old male horses and 42 male yearlings, kept in groups with permanent or rotational grazing. In 1984 only 90 male yearlings were investigated. In 1983 albendazole and ivermectin were used, 1984 ivermectin. The results of the faecal examinations showed that after ivermectin treatment ...
Floris B, Bini PP, Nuvole P, Di Meglio FG.The changes of some parameters in the blood serum of six Giara horses (3 males and 3 females) were checked weekly, in relation to the environmental temperature throughout a one winter and summer. T3, total lipids, triglycerides, urea nitrogen, creatinine, total protein, albumin, beta and gamma globulin showed significant difference between winter and summer and, with the exception of triglycerides, urea nitrogen and total protein were correlated to the environmental temperature. T4, glucose, uric acid and alpha globulin showed no difference between the two seasons and no correlation with the t...

Atkinson JP.1. The globulins of both normal and diphtheria antitoxic serum exhibit chemically toward reagents the same reactions, being precipitated by magnesium sulphate and split up into fractions in precisely the same way. 2. All of the diphtheric antitoxic power of both normal and immunized serum is always carried by the globulin and its fractional precipitates. 3. During the fractional precipitation of the serum globulin of horses immunized from diphtheria toxin and horses not immunized from diphtheria toxin, some of the globulin is lost, likewise at the same time some of the antitoxic power of the g...
