Topic:Prevalence
Prevalence in horses refers to the proportion of a specific population affected by a particular disease or condition at a given time. Understanding prevalence is essential for assessing the health status of equine populations and for guiding disease management strategies. It involves the collection and analysis of data to determine how widespread a condition is within different groups of horses, considering factors such as age, breed, and geographic location. Prevalence studies can provide insights into disease patterns, risk factors, and the effectiveness of control measures. This page compiles peer-reviewed research studies and scholarly articles that explore the prevalence of various diseases and conditions in horses, highlighting methodological approaches, findings, and implications for equine health management.
Prevalence and body distribution of sarcoids in South African Cape mountain zebra (Equus zebra zebra). There are no reports in the literature describing any tumours, and specifically sarcoids, in zebras. The equine sarcoid, a locally aggressive, fibroblastic skin tumour, is the most common dermatological neoplasm reported in horses. The Cape mountain zebra (CMZ) has been described as one of the most vulnerable mammals in South Africa with current populations existing in isolated units. All South African CMZ are descendants from no more than 30 individual animals originating from 3 populations, namely the Mountain Zebra National Park, and Kammanassie and Gamka Mountain Nature Reserves near Crado...
Estimated prevalence of polysaccharide storage myopathy among overtly healthy Quarter Horses in the United States. To estimate the prevalence of polysaccharide storage myopathy (PSSM) among Quarter Horses in the United States and evaluate possible relationships between muscle glycogen concentration, turnout time, and exercise level. Methods: Cross-sectional study. Methods: 164 overtly healthy Quarter Horses > 2 years old from 5 states. Methods: Horses with a history of exertional rhabdomyolysis or any other muscular disease were excluded. Muscle biopsy specimens were examined histologically for evidence of PSSM and were submitted for determination of muscle glycogen concentration. A diagnosis of PSSM wa...
Species composition of Gasterophilus spp. (Diptera, Oestridae) causing equine gastric myiasis in southern Italy: parasite biodiversity and risks for extinction. Horse gastrointestinal myiasis caused by larvae of Gasterophilus spp. (Diptera, Oestridae) flies has a worldwide distribution and, where present, it is primarily caused by larvae of Gasterophilus intestinalis and Gasterophilus nasalis. Other species, i.e., Gasterophilus inermis, Gasterophilus pecorum and Gasterophilus haemorrhoidalis, present in different or in the same regions of the gastrointestinal tract, were only occasionally reported in very limited areas of eastern European Countries and in central Italy. With the aim to contribute data on the species composition of Gasterophilus and on...
Gastric ulcers in standardbred racehorses: prevalence, lesion description, and risk factors. This study was performed to estimate the prevalence of gastric ulcers in Standardbred racehorses, to describe the lesion score and location, and to identify potential risk factors. Two hundred seventy-five (275) Standardbred horses from 5 training centers and 2 racetracks in Quebec, Canada, were studied. Historical data for the 2 months before examination were recorded for each horse, and the presence of gastric ulcers was determined by gastroscopy. A previously reported scoring system that used grades 0-3 for gastric lesions was used. Overall, 121 horses (44.0%; 95% CI, 38.1-50.1%) had gastri...
Epidemiological aspects of Babesia equi in horses in Minas Gerais, Brazil. The prevalence of Babesia equi in two climatic regions of Minas Gerais state was determined using the indirect fluorescent antibody test (IFAT) with blood samples obtained from horses in two slaughterhouses. Of 399 samples, 241 (60.4%) showed a positive reaction. Anti-B. equi antibody was detected in every county studied, the prevalence being 59.7% for horses in the area where the temperature rises above 18 degrees C in winter and 61.4% in the area where it remains below 18 degrees C, indicating that climatic variation has no substantial effect on the prevalence of the infection in Brazil. Blo...
Prevalence and risk factors in serous arthritis in the carpal joint of Norwegian coldblooded trotters. Of 508 four-year-old coldblooded trotters examined for carpitis, 135 (27%) had the condition. Thirty horses had unilateral carpitis on the left frontlimb, 52 on the right frontlimb and 53 had bilateral carpitis. Of these horses, 105 were stallions, 135 were geldings and 269 were mares. The prevalence of carpitis in these three groups was 25%, 25% and 28%, respectively. Information was obtained on the training regimes in four periods of the life of 378 horses. The odds ratios for the training variables were of the same order in all four periods. In logistic regression analyses on the training v...
[Anoplocephala sp. prevalence in equines at the Sociedade Hípica Paranaense, Curitiba, PR]. Anoplocephala sp. parasites are among the most frequent tapeworms in equines and are associated with intestinal infections. This survey had the objective to verify Anoplocephala sp. prevalence at Sociedade Hípica Paranaense (SHPr). The animals were treated with ivermectin, which does not have efficacy against Anoplocephala sp.. To determine whether eggs of Anoplocephala sp. were present, a modified centrifugal flotation technique was used and also eggs per gram of faeces (EPG). None of the samples showed Anoplocephala sp. eggs and only 11% of the animals had positive values for EPG. The resul...
