Recia [online]. 2020, vol.12, n.2, pp.86-92. Epub 28-Ago-2021. ISSN 2027-4297. https://doi.org/10.24188/recia.v12.n2.2020.788.
Two female bovines, both of the Brahman breed, a 15-month-old heifer weighing 150 Kg and a cow were treated by the Outpatient Clinical Service of Large Animals of the Faculty of Veterinary Medicine and Zootechnics of the University of Córdoba. 5 years old and weighing 400 kg, both cases located in the municipality of Cereté, Córdoba. The anamnesis indicates that the 15-month-old heifer began showing a slight cutaneous swelling at the ventral abdominal and pectoral region, with a progressive increase in volume of the affected area during a week, in the same way, the 5-year-old cow began with redness of the skin of the mammary gland and nipple. A general and specific clinical examination of the integumentary system was carried out, where the characteristics of the lesion were analyzed, as well as the possible presumptive diagnoses, based on the shape, location, extension, humidity and depth of the lesion; and the epidemiological conditions of the area. In both animals, the lesions were characterized in common by progressive necrosis, with an erythematous and edematous area, the presence of a central necrotic spot and a whitish medial halo and a purplish outer halo, hyperesthesia in the area. The importance of knowing the epidemiology of the dermatological alterations in cattle in the Department of Córdoba is concluded, as well as the good use of the clinical examination, the characterization of the lesions and the presence of the spider in the bovine farms where cases of dermonecrosis occur for the correct diagnosis of loxoscelism.
