Resumo: Relata-se a ocorrência de orquite e epididimite ovina associada ao isolamento de Actinobacillus seminis no Estado de Pernambuco. Clinicamente observou-se aumento de volume nos testículos e epidídimos, dor e aumento de temperatura local à palpação, e atrofia testicular bilateral. Após o abate observou-se a presença de conteúdo purulento no epidídimo. À microscopia dos testículos observou-se espessamento da túnica albugínea, necrose de coagulação e calcificação de túbulos seminíferos, infiltrado inflamatório com predominância de linfócitos entre túbulos seminíferos, além de mineralização incipiente de túbulos. No epidídimo observou-se intensa proliferação de tecido conjuntivo ao redor dos ductos epididimários. O diagnóstico de orquite e epididimite por Actinobacillus seminis foi confirmado pela associação dos achados clínico-patológicos, isolamento e identificação da bactéria.
[Sheep epididymitis by Actinobacillus seminis in the state of Pernambuco, Brazil].
This study reports the occurrence of sheep epididymitis and the isolation of Actinobacillus seminis in the state of Pernambuco, Brazil. An increase in volume of the testicles and epididymis, pain and increase in the local temperature at palpation, and bilateral testicular atrophy were clinically observed. After slaughter, the presence of purulent content in the epididymis was found. In microscopy of the testicles, coagulation necrosis and calcification of seminiferous tubules, thickening of the tunica albuginea, fibrosis, inflammatory infiltrate with predominance of lymphocytes between seminiferous tubules and incipient mineralization of tubules was observed. In the epididymis, intense proliferation of conjunctive tissue and fibrosis around the epididymal ducts was found. The diagnosis of epididymitis by Actinobacillus seminis was confirmed with association of the clinical findings, isolation and identification of the bacteria, as well as through histopathological exam.

This paper aims to explore the production of porous Nb2 O5 pellets by pressing and adding anaerobic biomass (sludge) in order to evaluate the microstructure porosity. The thermal treatment temperature of the pellets varied between 300 ºC and 900 ºC. Their structural, morphological, and physical properties were measured, and the adsorption potential of Mn2+ and their reuse were evaluated. All samples had a monoclinic phase. Density average values of samples pressed using sludge ranged between 2.45 and 2.52 g.cm-3, while the one obtained without sludge pressing achieved higher values of around 2.72 g.cm-3. All samples presented high porosity values after the heat treatment (above 40%), which confirms the efficiency of sludge as a means to enhance porosity. These pellets were used for Mn2+ ions adsorption in aqueous medium. The Langmuir isotherm model was the one that achieved the best goodness-of-fit. In kinetic studies, the adsorption reaction was in accordance with second-order kinetics. Adsorbents in the form of pellets are environmentally friendly on account of their significant reuse and recycling potential. However, the particulate matter might become an environmental liability and incur high treatment costs. The samples proved to be reusable, promoting the adsorption of 67% of the Mn2+ after the fifth reuse cycle. |
