Topic:Clinical Symptoms
Clinical symptoms in horses encompass a range of observable signs that may indicate underlying health issues, such as disease, injury, or physiological stress. These symptoms can vary widely depending on the condition and may include changes in behavior, appetite, respiratory patterns, or physical appearance. Common clinical symptoms in horses include lameness, colic, coughing, nasal discharge, and changes in body temperature or heart rate. Identifying and interpreting these symptoms is an essential aspect of equine veterinary practice, as they provide critical information for diagnosis and management of health conditions. This page compiles peer-reviewed research studies and scholarly articles that explore the identification, assessment, and implications of clinical symptoms in equine health management.
Contagious equine metritis: effect of intrauterine inoculation of contagious equine metritis agent in pony mares. Actively growing culture of contagious equine metritis (CEM) bacteria or infective exudate (or both) were inoculated intrauterine in pony mares. A direct relationship was observed between (i) appearance and duration of cervicitis and vaginitis and (ii) vaginal exudate. Clinical signs appeared 1 to 3 days after mares were inoculated and lasted 7 to 23 days. In the acute phase of infection, all uterine and cervical samples yielded CEM bacteria. In the asymptomatic stage of infection, CEM bacteria were not isolated from uterine and cervical samples; however, in 33%, 28%, and 20% of the pony mares...
Equine villonodularsynovitis: a case survey. Nineteen cases of villonodular synovitis as identified in 14 horses are presented. Physical and radiographic findings are discussed and the surgical correction described. Case histories indicate that surgical extirpation of the lesion is corrective and that rest without surgical intervention is ineffective. Radiation therapy following surgery does not appear to be necessary.
Ultrastructure of Haemophilus equigenitalis, causative agent of contagious equine metritis. Haemophilus equigenitalis, a proposed new species of Haemophilus and the causative agent of contagious equine metritis, a venereal disease of the horse, had ultrastructural characteristics of gram-negative bacteria. The organism additionally had a small, threadlike capsule that was removed by heating in phosphate-buffered saline solution. Heating also detached the outer membrane from the cytoplasmic membrane. The capsule could only be demonstrated when bacterial were stained with ruthenium red during the preparation of ultrathin sections. The gross morphology of newly isolated organisms (rodli...
Postural effects on lung volumes and asynchronous ventilation in anesthetized horses. Quasi-static pressure-volume curves and single-breath nitrogen washouts were performed simultaneously on eight anesthetized horses (average body wt = 485 kg) in left lateral, right lateral, prone, and supine postures (sequence randomized). The shift from prone to lateral or supine posture decreased expiratory reserve volume (ERV), vital capacity (VC), residual volume (RV), functional residual capacity (FRC), and total lung capacity (TLC); RV and FRC expressed as %TLC were unchanged, suggesting that in the lateral and supine postures a significant portion of the lung volume was not recruited by...
[Findings on an epidemic of human trichinelliasis verified in Italy]. The present article completes the information already given in previous papers (Mantovani et al., 1976; Bellani et al., 1977; Mantovani, 1978) and is connected with the research on the infection of horses by Pampiglione et al. (1978). In September 1975 an epidemic of Trichinellosis involving at least 89 people was reported at Bagnolo in Piano (Reggio Emilia). This present article describes the epidemiological investigations. In the introductory part, the Trichinellosis outbreaks are summarized which were reported in Italy during this century along with research on domestic and wild animals. Th...
Virus and its relationship to the “poor performance” syndrome. Racehorses perform badly for many different reasons. Trainers often expect clinicians to determine the cause in individual cases and, more especially, where most of the immates of the stable are apparently affected by loss of form. Clinical examinations may reveal signs including fever, serous nasal discharge and the occasional cough. Haematology and blood biochemistry are commonly used aids to diagnosis in the field and may be helpful, but there is a need for facilities for virological investigations to be made readily available for use by clinicans as an adjunct to more commonplace laborator...
[Head and neck injuries in equestrian accidents (author’s transl)]. Horses' kicks can produce two types of head and neck injuries: injuries of the mid-face and injuries of the larynx. Typical cases as seen by the author are presented. The treatment of mid-face injuries is performed according to principles of plastic surgical repair. After frontal-nasal injuries, a revision of the nasal septum must be done. Involvement of the larynx requires external layer repair of mucosa and cartilage.
Surgical repair of fractured capital femoral epiphysis in three foals. Fracture of the capital femoral epiphysis occurred in three foals. One fracture was repaired by means of pinning under radiographic control and the two other fractures were repaired by means of trochanteric osteotomy.
Mesodiverticular bands as a cause of small intestinal strangulation and volvulus in the horse. Volvulus of the jejunum and ileum in three horses was associated with intestinal strangulation in a mesenteric rent. The rent was in the jejunal mesentery at its point of attachment with an anomaly that was classified as a mesodiverticular band. The band also was attached to the dorsolateral surface of the jejunum, thus forming one side of a triangular hernial sac that was completed on the other side by the adjacent jejunal mesentery. Incarceration of a loop of small intestine in the hernial sac preceded rupture of the jejunal mesentery and subsequent intestinal strangulation. Surgical correct...
Simulated small intestinal volvulus in the anesthetized horse. Experimental closed loop small intestinal volvulus was studied in the anesthetized horse. Volvulus was simulated by ligation of the mesenterial veins to a segment of small intestine. Physical signs and hemodynamic, hematologic, clinical chemical, bacteriologic and peritoneal fluid values were examined. Compared to conscious horses anesthesia highly delayed and modified the clinical signs of shock (changes in mucosal colour, dehydration, decreased skin temperature, elevated pulse rate, low blood pressures) and of small intestinal volvulus (altered peristalsis, gastric dilation). Plasma glucose ...
Minimal changes in blood cell counts and biochemical values associated with prolonged isoflurane anesthesia of horses. The potential toxicity to horses of 7.33 +/- 0.87 SD minimal alveolar concentration hours of isoflurane anesthesia was evaluated by sequential determination of blood cell counts, electrolyte concentrations, and certain blood chemical values. Minimal or no serious toxicosis was observed for up to 7 days after anesthesia was terminated.
Dorsal displacement of the left ventral and dorsal colon in two horses. This paper describes the clinical signs and surgical treatment of 2 cases of dorsal displacement of the left ventral and dorsal colon. The condition, in which the colon becomes enclosed in the space bounded by the base of the spleen, the dorsal aspect of the suspensory ligament of the spleen (phrenicosplenic ligament), the left kidney and the adjacent body wall, is characterised by moderate to severe pain, minimal signs of shock, no response to medical therapy and a tendency for a ventral midline abdominal paracentesis to enter the spleen. Both horses recovered after surgical replacement of th...

In this article a description is given of the clinical and postmortem findings of a persistent right aortic arch in association with a persistent left ductus arteriosus and a ventricular septal defect in a horse.
