Pathology in horses involves the study of diseases and abnormalities affecting equine health, encompassing a range of conditions that can impact various systems within the horse's body. This field examines the causes, mechanisms, and effects of diseases, as well as the structural and functional changes they induce in equine tissues and organs. Common pathological conditions in horses include laminitis, colic, equine infectious anemia, and respiratory disorders. Understanding these diseases involves evaluating clinical signs, diagnostic methods, and treatment options. This page compiles peer-reviewed research studies and scholarly articles that explore the etiology, pathogenesis, and clinical implications of pathological conditions in horses.
To compare ocular structures of Quarter Horses homozygous for hereditary equine regional dermal asthenia (HERDA) with those of Quarter Horses not affected by HERDA (control horses) and to determine the frequency of new corneal ulcers for horses with and without HERDA during a 4-year period. Methods: Cohort study of ocular structures and retrospective case series of horses with and without HERDA. Methods: The cohort portion of the study involved 10 Quarter Horses with HERDA and 10 Quarter Horses without HERDA; the retrospective case series involved 28 horses with HERDA and 291 horses without HE...
is one of the most pathogenic nematodes affecting equids. Larval migration through the cranial mesenteric artery (CMA) with attendant arteritis and thromboembolism can result in fatal non-strangulating intestinal infarction. Once considered a historical disease, recent studies have described the reemergence of this pathogen in several European countries; however, little is known of the current prevalence of in the Canadian horse population. Unassigned: To determine the prevalence of active cranial mesenteric arteritis in horses submitted for postmortem examination to the Diagnostic Services...
Rouby S, Ewies S.Bovine papillomatosis is an infectious viral disease of cattle characterized by development of benign cutaneous warts. The present study describes bovine papillomavirus infection in cattle on clinco-pathological and molecular bases and compares the identified strains with the previously characterized papillomavirus isolates in Egypt either of bovine or equine origin. Out of sixty examined cattle, skin lesions were collected from eleven clinically diseased cattle exhibiting typical papillomatosis clinical signs and subjected to histopathological and molecular identification. Histological sectio...
Murphy S.Cancer is disease of the genome. The Hallmarks of cancer are a way of thinking of cancer to help rationalize what occurs in this disease process. A solid tumor is a complex of normal and neoplastic cells, arising through an evolutionary process to survive and grow. By understanding how normal cellular mechanisms are subverted to promote cancer we can refine our approach to improve outcomes. It gives us opportunities to prevent some cancers and allowing earlier diagnosis. We can refine conventional diagnostic tools and give more accurate prognoses. It offers novel targets to improve treatment o...
Ouchetati I, Khelifi Touhami NA, Bouasla I, Ouchene N.Toxoplasma gondii is one of the world's most widespread polyxenic protozoan parasites that affect all warm-blooded animals, including humans. This survey aims to study, for the first time in Algeria, the seroprevalence of Toxoplasma infection in zoo animals. The study included eight animal species of which 54 serum samples were collected from 30 Australian goats (Capra hircus), four bulls (Bos taurus), one dromedary (Camelus dromedarius), three cuffed sheep (Ammotragus lervia), seven donkeys (Equus asinus), one pony (Equus ferus), four bearded horses (Equus ferus caballus) and four rabbits (Or...
Jochumsen S, Kk Vishram-Nielsen J, Pump BB, Seibæk MB, Bruun NE.Infective endocarditis (IE) is a dreaded disease with a high mortality rate. In Denmark, IE is most often caused by or species. We present a rare case of a 50-year-old woman with a history of a dual-chamber pacemaker due to third-degree atrioventricular block and a mechanical mitral valve inserted due to mitral stenosis. The patient was admitted to the hospital after she was found lying on the floor in her home. The patient was diagnosed with subspecies () prosthetic heart valve IE, which was complicated with meningitis, myocardial infarction, and an increasing vegetation load despite antib...
de Mello Zanim M, Rodriguez MC, Martins FDC, Camargos MF, Headley SA.West Nile fever is a zoonotic arboviral disease caused by the West Nile Virus (WNV), responsible for deaths in humans, mammals, and birds with associated neurological manifestations. All previous investigations of WNV from Brazil were based primarily on serological and molecular analyses and in humans, equids, and birds in the northern and southeastern regions of the country. This study describes the pathological and molecular findings observed in a mule, from the state of Paraná, southern Brazil, that died during an outbreak involving equids with clinical manifestations of a neurological dis...
