Tetanus in horses is a serious condition caused by the bacterium Clostridium tetani, which is commonly found in soil, dust, and manure. The bacterium produces a potent neurotoxin that affects the nervous system, leading to muscle stiffness and spasms. Horses are particularly susceptible to tetanus due to their environment and the likelihood of sustaining wounds that can become contaminated. Clinical signs of tetanus in horses include stiffness, difficulty moving, and an elevated tail. Preventative measures, such as vaccination, are essential to mitigate the risk of infection. This page compiles peer-reviewed research studies and scholarly articles that explore the pathophysiology, diagnosis, treatment, and prevention of tetanus in equine populations.
Gibson RB, Banzhaf EJ.Gravimetric determinations were recorded for the total and several individual proteins (in the sodium oxalate plasma) fractioned with ammonium sulphate and sodium chloride. At precipitation, the plasma salt mixture had been diluted to a final volume of ten times the amount of plasma employed. Coagulations were on aliquot portions of filtrates, and the individual protein constituents (except serumalbumin) were calculated by difference. The eleven horses had been subjected to simultaneous immunization against diphtheria and tetanus toxins, each horse being subsequently continued on the toxin to ...
Kampl B, Dominis-Kramaric M, Bacar-Huskic L.The activities of leukocyte alkaline phosphatase (l-AP) and serum gamma-glutamil transferase (gamma-GT), and total leukocyte counts were determined in horses submitted to the production of hyper immune sera against tetanus (Clostridium tetani). The purpose of this work was to investigate the prospective changes of mentioned parameters in horses under the described circumstances. In addition, the suitability of these parameters in assessing the health condition of the same horses had to be evaluated. The average total leukocyte count increased in one month from the values considered as physiolo...
Rosskopf U, Noeske K, Werner E.The bacterium Clostridium (C.) tetani is an ubiquitous pathogen. This anaerobic, gram-positive bacterium can form spores and can be found in the whole environment. It enters the body via injuries of the skin and wounds where it releases the neurotoxin "tetanospasmin" (= tetanus toxin). The animals most susceptible to tetanus infection are horses and sheep. Only active immunisation by tetanus vaccine provides effective protection against tetanus intoxication. The marketing authorisation requirements stipulate that efficacy of tetanus vaccines ad us. vet. must be demonstrated in all target anima...
Elghoul N, Jalal Y, Bouya A, Zine A, Jaafar A.Almost 2% of all emergency admissions involve an animal bite. While horses bite humans very rarely, their bites are mostly associated with fatalities. Herein, we report the case of a 23-year old bitten by a domestic horse causing a crush injury to his fourth finger with fracture dislocation of the proximal interphalangeal joint. The patient benefited upon arrival at the emergency department from copious irrigation with saline serum, tetanus toxoid, postexposure rabies vaccination, and prophylactic antibiotic therapy. In the operating room, surgical exploration found the ulnar digital pedicle s...
Lensing HH, Behr-Gross ME, Daas A, Spieser JM.The European Directorate for the Quality of Medicines (EDQM) has organised an international collaborative study, divided into two phases, aimed at producing and establishing two suitable reference sera for serological potency testing of tetanus vaccines for veterinary use for batch consistency demonstration. In phase I pools of sera were produced by immunising guinea pigs and rabbits with tetanus toxoid using the immunisation schedule prescribed by the European Pharmacopoeia (Ph. Eur.) for potency testing of tenanus vaccines for veterinary use. Following aliquoting and freeze-drying, character...
Radvila P.The effect of heterologous and homologous antitoxin is the same if an equal amount of antitoxin is present in the organism. In man there are no circulating antibodies in the blood after the first injection of the toxoid because there is no natural immunity against the tetanus antigen. After the second injection, man develops the same immunity as animals. Large antitoxin doses protect people for a longer period than small doses. Normally 3,000 I. U. of the heterologous antitoxin protects people for 2 to 3 weeks. In man and sheep 2 ml of the adsorbed vaccine produces an earlier and longer-lastin...
Wilde H, Thipkong P, Sitprija V, Chaiyabutr N.Active immunization against infectious disease is important. However, much of our world faces poverty, social injustice, and warfare, all of which cause universal immunization to remain a distant dream. Agents that provide passive immunity thus remain essential biologicals. The most important of these are human or equine antisera against rabies, tetanus, diphtheria, and snake antivenins. Homologous products are either unavailable or unaffordable in places where they are needed the most. Less expensive heterologous (equine) antisera can be purified and are safe to use, but these antisera are al...
Koren L, Stahl S, Rovitsky A, Peled E.Amputation of fingers with tendon avulsion occurs through a traction injury, and most occur through a ring avulsion mechanism. Usually the flexor digitorum profundus is torn out with the amputated finger. Replantation usually is recommended only when the amputation is distal to the flexor digitorum superficialis insertion. Animal bites are relatively common, with a decreasing order of frequency of dogs, cats, and humans. Horse bites are relatively infrequent but are associated with crush injuries and tissue loss when they occur. This article describes a 23-year-old man with amputation of his m...
Uzal FA, Navarro MA, Asin J, Henderson EE.The clostridial diseases of horses can be divided into three major groups: enteric/enterotoxic, histotoxic, and neurotoxic. The main enteric/enterotoxic diseases include those produced by Clostridium perfringens type C and Clostridioides difficile, both of which are characterized by enterocolitis. The main histotoxic diseases are gas gangrene, Tyzzer disease, and infectious necrotic hepatitis. Gas gangrene is produced by one or more of the following microorganisms: C. perfringens type A, Clostridium septicum, Paeniclostridium sordellii, and Clostridium novyi type A, and it is characterized by ...
Cryz SJ.At the time the Swiss Serum and Vaccine Institute Berne (BERNA) was found in 1898, few vaccines or immune globulins were available. This short list included vaccines against cholera, typhoid fever, plague, smallpox and rabies and equine anti-tetanus and diphtheria immune globulins. Furthermore, their use was restricted due to limited production capacity, uncertainty regarding safety and no public health infrastructure to promote their utilization. Today, safe and effective vaccines exist for more than 30 infectious diseases while human hyperimmune globulins exist to treat or prevent rabies, te...
Terpeluk ER, Schäfer J, Finkler-Schade C, Schuberth HJ.Feed supplements supporting animal welfare and performance are becoming increasingly important. Immunomodulatory effects of such products have been observed in many species. The aim of this study was to analyze whether food supplementation with a fermentation product (SCFP) affects the occurrence of foal diarrhea in early life, and whether the SCFP feeding has an impact on the immediate response to a parenteral vaccination at the age of 6-9 months. Eleven foals received the SCFP (OLI) and eleven foals were fed a placebo (PLA) for 29 days. Growth, diarrhea, and diarrhea severity were observed ...
Vaccination is one of the most important measures for preventing infectious diseases. Vaccinations against tetanus and West-Nile-Virus are essential to protect the individual horse. These infections are not contagious and are not transmitted from animal to animal. By contrast, Equine Influenza and Equine-Herpes-Virus infections are highly contagious, transmissible diseases. In addition to protecting the vaccinated individual, vaccinating as many horses as possible aims at inducing a broad herd immunity, which interrupts infection chains and thus additionally protects the individual. Vaccinatio...
Perzyna M, Grzędzicka J, Milczek-Haduch D, Dąbrowska I, Trela M, Pawliński B, Witkowska-Piłaszewicz O.Donkeys are routinely vaccinated with protocols developed for horses, yet species-specific data on their immune responses are limited. Objective: We hypothesized that donkeys exhibit robust T-cell-mediated immunity and regulatory adaptation after vaccination, comparable to horses. Methods: Thirty-six healthy, seronegative donkeys (34 mares, 2 stallions), aged 0.5-23 years (median 8 years), from two farms with similar housing and management conditions. Methods: Prospective study. Animals were selected based on clinical health assessment and confirmed seronegativity for tetanus and equine in...
