Folin M, Gennari G, Jori G.The irradiation of horse and sperm-whale Fe” or Fez’ myoglobins with visible light
showed that axial ligands that render the heme diamagnetic (e.g. 02, CO or CN-) endow the
hemoproteins with a marked photosensitivity. In contrast, high-spin myoglobins are unaffected by
visible light. These findings appear to be of general validity for all hemo-proteins and are in agreement
with the involvment of the triplet state of the heme as the reactive intermediate. In all cases, the overall
photoprocess occurs within a very narrow spatial range, leading to specific modification of these
photoox...
Augustinsson KB, Bartfai T, Mannervik B.The steady-state kinetics of the butyrylcholinesterase-catalysed hydrolysis of butyrylthiocholine and thiophenyl acetate were shown to deviate from Michaelis-Menten kinetics. The ;best' empirical rate law was selected by fitting different rate equations to the experimental data by non-linear regression methods. The results were analysed in view of two alternative interpretations: (1) the reaction is catalysed by a mixture of enzymes, or (2) the activity is due to a single enzyme displaying deviations from Michaelis-Menten kinetics. It was concluded that the second alternative applies, and this...
Margalit R, Schejter A.The specific binding of cations to horse heart ferrocytochrome c has been studied, using the gel
filtration method. The cations investigated were: Mg2+, Co2+, cinchonine and proflavine. The stability
constants are in the range of 5-8 mM-1, and the number of binding sites per protein molecule are
1 to 2. The temperature dependence of the stability constant for the Mg2+-ferrocytochrome system
was measured. The thermodynamic parameters were found to be: dH&s = 4-12 kcal/mol, dG;,,
(25 "C) = -5.6 kcal/mol and AS&, = +57 calxmol-lx K-I.
Hariharan H, Barnum DA, Mitchell WR.Prevalence of antimicrobial drug resistance among over 3000 clinical isolates of animal pathogens in Ontario during 1971-72 has been studied. A high number of multiple resistance patterns is prevalent among members of Enterobacteriaceae, especially Escherichia coli and Salmonella typhimurium. The most common resistance pattern among bovine strains was against not less than six drugs in common use. Among different animal species the bovine population was found to be the source of a high percentage of chloramphenicol resistant E. coli and S. typhimurium organisms. All the isolates resistant to t...

Faulk C.Sequencing a genome by students has now become practical as we demonstrated with our recent publication of the Przewalski's horse (Equus ferus przewalskii) genome. In this review, I describe my experience teaching genome assembly in the classroom. In my course, students sequenced, assembled, and published a high-quality genome for Przewalski's horse using Oxford Nanopore long-read sequencing with only $4000 of materials. Along with the genome, we assembled the mitochondrial genome, sequence variants, predicted gene annotations, and DNA methylation levels. Our genome statistics far exceeded the...
Bordoni T, Dini FM, Morini M, Rinnovati R, Spadari A, Galuppi R.Mycetoma is a fungal chronic skin proliferative lesion rarely encountered in horses and often associated with fungi such as Scedosporium spp., Madurella spp., Phialophora spp., Curvularia spp., and less frequently with Aspergillus spp. A case of subcutaneous mycetoma in the cervical region in a 7-year-old male Quarter Horse, diagnosed through cytological, histological, cultural and molecular methods, is reported. Aspergillus nidulans, usually implicated in guttural pouch mycosis, was identified. This unusual case represents the second case report of mycetoma caused by Aspergillus nidulans in t...
MacNeill AL, Micheloud JF, Parvin R, Gjessing M, Airas NA, Sant'Ana FJF, Adamek M.Zoonotic poxviruses, including monkeypox virus (MPV), the causative agent for Mpox disease, have gained significant media and scientific attention due to recent outbreaks in human populations across the globe. The increase in human cases of poxvirus infection is not unexpected, as routine vaccination against smallpox (a disease caused by the poxvirus variola virus, which cross protects against other orthopoxviruses) was discontinued in the 1980s after its eradication. Large numbers of vertebrate and invertebrate species are susceptible to infection by . Clinical signs and histologic lesions ca...
Farchati H, Merlin A, Saussac M, Dornier X, Dhollande M, Garon D, Tapprest J, Sala C.Identifying and tracking equines are key activities in equine health prevention. France is one of the few European countries with an operational centralized database that records information on equines, owners, and keepers but not on the location and keeping conditions of equines. The objective of our study was to collect information on keeping habits of equines and the relative location of a wide range of equines, owners, and keepers and discuss their implication for surveillance and control of outbreak improvement. A national email survey was conducted among the 1.9% of people registered as ...
Cserhalmi D, Wermer K.Our paper presents a case study of a Welsh pony mare with grazing-induced severe urticaria. The main clinical signs were eye swelling, depression and extensive urticaria. Physical examination revealed no other abnormalities. Botanical sampling revealed horseweed (Conyza canadensis) as the most abundant species and a potential allergen plant due to sesquiterpene lactones (SQL). Differential diagnosis strongly suggested that the clinical signs were the result of a hypersensitivity reaction to this plant. Former studies brought controversial data about the toxic or allergic potential of horsewee...
Tually P, Currie G.While the establishment and operation of an equine nuclear medicine department share several principles with those of human nuclear medicine departments, they require an additional skill set to ensure safe and effective operation. This article explores the practical aspects of equine nuclear medicine facility location and design and details important considerations for safe and practical operation. Key considerations associated with the differences in physical and radiation safety and imaging approaches are explored. Specific adaptations of γ-camera gantries to allow either planar imaging or ...
Nieman RT, Lamim LI, Del Fava C.Fetal loss in mares can result from a range of causes, including infectious agents or noninfectious conditions such as neoplasia, which may originate from either the fetus or the dam. Among neoplastic conditions, teratomas are rarely reported and, to date, have not been described in the equine fetal testis. Teratomas arise from the partial differentiation of pluripotent germ cells and may occur in young and adult horses, typically in cryptorchid testes. Their gross and histopathological features vary widely between cases. This report describes a rare case of bilateral fetal testicular teratoma...
Croll TP, Swanson BZ.Early in the 1900s, a Philadelphia Horse Dentist apparently had a jolly sense of humor. A business card with a fun reverse is evidence of that. In 1876 Peter J. Haley, Sr. founded a veterinary horse parlor business in Philadelphia, Pennsylvania, and his sons Peter Jr. Haley and James Raymond Haley carried their father's work forward, after his death.
Satué K, Medica P, Fauci D, Gímenez ED, Fazio E.Catecholamines (CATs) are essential neuroendocrine regulators with plasma concentrations that naturally fluctuate during pregnancy. Age-related changes in CATs, observed in humans and animals, suggest that gestation and aging together influence catecholaminergic activity. Blood samples were collected from Spanish Purebred mares categorized into three age cohorts (4-7 years, n = 18; 8-10 years, n = 18; 11-15 years, n = 18) across four defined gestational stages: first trimester (T1), second trimester (T2), third trimester (T3), and the final bimester (B4). Plasma concentrations of a...
Cornelisse K, Ionescu AM.Keesjan Cornelisse and Andra-Maria Ionescu discuss the clinical presentation, investigation and diagnostic approach to a case of orthoflavivirus infection in a horse in south-west England.
Magdesian KG.Knowledge of immunodeficiencies is crucial to neonatal medicine, in that they predispose to sepsis in the newborn and neonatal foal, as well as recurrent infections in older foals. The most common immunodeficiency in newborn and neonatal foals is failure of passive transfer, which is an example of an acquired immunodeficiency. Congenital or developmental immunodeficiencies may be transient or permanent, and can either affect the cell-mediated or humoral arms of immunity, and in some cases both. Affected foals often have chronic or recurrent respiratory or gastrointestinal infections, often wit...
Kuwabara M, Inukai N, Inanami O, Miyake YI, Tsunoda N, Maki Y, Sato F.Hotbred (Thoroughbred) horses were grouped into three classes according to the levels of constant physical exercise (foals, 6 months old; racing horses, 5 years old; horses for breeding, 6-10 years old), and lipid peroxide levels in their sera were measured as thiobarbituric acid-reactive substances. No significant differences were observed among them. The superoxide-scavenging abilities of sera were measured next; to examine the antioxidative properties of hotbreds, and were found to be highest in the racing horses. The higher scavenging ability of the racing horses might contribute to keep t...
Aboelmaaty AM, El-Seadawy IE, Kotp MS, Mohamed AA, El-Debaky HA, El-Badry DA, Anwer AM, Tsvetkov T, Daneva T, Elgabry MA.Alpha-tocopherol is one of the non-enzymatic lipophilic antioxidants. Butylated hydroxytoluene (BHT) is a synthetic analog with similar modes of action in protecting the cryopreserved sperms. Objective: This study hypothesized that a certain concentration of any antioxidant is suitable for improving the post-thaw semen quality of stallions. Methods: To determine the optimum BHT concentration, a synthetic antioxidant similar to vitamin E in potency and scavenging oxidative stress power in concentrations of 0.0, 0.25, 0.50, 1.0, 2.0, and 4.0 mM/ml were added to semen extender. The post-thaw sper...
Morales CJ, Costa LRR.The practice of medicine has always been associated with complications. In fact, in its early stages, these complications contributed to the understanding of certain diseases and advancement of the medical field. In equine practice, virtually every procedure carries an associated risk. In fact, even procedures that would have minimal risk in human medicine may pose significant risk in equine practice owing to the unique nature of the horse. For instance, a simple rectal palpation could result in a rectal tear following an unexpected movement of the patient. Thus, extrapolations of complication...
