ABSTRACT
Background: Rabies is an infectious disease that is important in the One Health worldwide with high lethality rate. The etiological agent is a neurotropic virus, genus Lyssavirus, transmitted mainly through the saliva of infected animals. For equines, the bite of hematophagous bats is the main source of infection. Piauí is an important state for equestrian sports and the increase in the number of horses with neurological clinical signs without diagnosis has increased in recent years. In this context, the aim of this study is to report to the scientific community a confirmed case of equine rabies in the Santa Luz county, Southernmost state of Piauí, Brazil. Case: A 3-year-old female non-defined breed horse, was admitted to the Hospital Veterinário da Universidade Federal do Piauí (UFPI/CPCE). The equine had difficulty walking 2 days ago, in the panoramic inspection was restless and disoriented in the paddock. Rectal temperature of 38.2°C, heart rate of 60 bpm, respiratory rate of 40 mpm, congested mucosa and dyspnea were verified. With the progression of the neurological signals, it positioned itself in a lateral decubitus with pedaling movements, hyperesthesia, dysphagia and paralysis of the hindlimbs. The clinical suspicion was rabies and the Agência de Defesa Agropecuária do Piauí (ADAPI) was communicated to euthanize the animal and collect samples for diagnosis in accordance with official standards of the Ministério da Agricultura, Pecuária e Abastecimento (MAPA). At necropsy, there was slight brain hyperemia, with no other significant organ changes. Fragments of the cerebellum, cortex, hippocampus and spinal cord were collected and sent at a temperature of 4°C to perform the Direct Immunofluorescence (DIF) assay. Samples for histopathology were not collected because they do not include assay for confirmatory diagnosis of rabies. The DIF technique with...(AU)

The aim of this study was to evaluate the morphogenesis of rheas reproduction equipment featuringgonadal differentiation phase. We used eight fetuses, obtained from eggs, the Study Group Preservation of WildAnimals UFPI. The animals were fixed in formalin 5% 70% alcohol, dissected and analyzed bystereomicroscopy. Fragments of the urogenital organs were dehydrated in alcohol, diaphanized in xyleneemblocados and subjected to 5μm sections stained with hematoxylin-eosin. It was found in fetus 14 days theurogenital structures as two elongated bodies, dorsally in the coelomic cavity, lateral to the midline, andflattened dorsoventrally, the urogenital ridge; 18 days were divided medially, forming new ventral massprimitive gonads and a dorsal primitive kidneys; 21 days, were completely separated, the lobate kidneys andgonads with smooth surfaces and fetus of 30 days was observed the evolution of the development of the gonads.The rhea sexual differentiation phase occurs on the 14th day of fetal development.
