A especie Hymenaea courbaril var. stilbocarpa tem importancia economica, ocorrendo em Matas de Galeria do bioma Cerrado. O objetivo deste trabalho foi estudar o crescimento inicial de H. courbaril var. stilbocarpa sob diferentes condicoes de sombreamento em viveiro. O delineamento experimental foi inteiramente casualizado com 12 repeticoes por tratamento. Os tratamentos estabelecidos foram: pleno sol, 50%, 70% e 90% de sombreamento. A altura, o diametro do coleto e o numero de folhas foram monitorados dos 12 aos 21 meses. O peso seco foi medido aos 21 meses tambem. O maior valor medio de altura alcancado (80cm) foi na condicao de 70% de sombreamento, aos 21 meses. Com a mesma idade, os maiores diametros medios do coleto ficaram em torno de 10,50 mm, nas condicoes de pleno sol e 70% de sombreamento. O maior valor significativo do numero de folhas (14) ocorreu na condicao de 50% de sombreamento. A tendencia de maiores valores significativos de massa seca total ocorreu sob as condicoes de pleno sol (65,30g) e de 50% de sombreamento (59,00 g). Os dados indicam que H. courbaril var. stilbocarpa pode ser utilizada na recuperacao de Matas de Galeria desde a condicao de bordas e clareiras ate o fechamento de dossel. |

Infectious bovine keratoconjunctivitis (IBK) is a widespread, contagious ocular disease that affects cattle, especially dairy breeds. The disease is caused by Gram-negative bacteria mainly Moraxella bovis, and its treatment consists of parenteral or topic antibiotic therapy. The topic treatment approach is used more commonly in lactating cows, to avoid milk disposal. However, treatment failures are common, because the antibiotic is removed during lacrimation. This study aimed to evaluate the susceptibility of commercial cloxacillin and evaluate the efficacy of nanostructured cloxacillin in clinical cases of IBK by Moraxella. The minimum inhibitory concentration (MIC) of nanoparticle cloxacillin nanocoated, the nanoparticle without the antibiotic and the commercial cloxacillin were determined in vitro with field samples of Moraxella ovis (5) and Moraxella bovis (5). The efficiency of nanoparticles was tested in three cows naturally infected that were treated with 1.0 mL (with 0.32 mg of nanostructured cloxacillin) for the ocular route. Moraxella bovis was isolated and identified by biochemical and molecular methods before the treatment. The animals were treated every 12 h for six days. The cure was considered by the absence of clinical symptoms and bacteria after treatment. The mucoadhesive nanoparticlebased formulation promoted clinical cure with a low number of doses of antibiotics, probably due to the maintenance of the MIC in the ocular mucosa for longer due to the mucoadhesive characteristics of the nanoparticle. The results indicate that the use of nanocoated cloxacillin is possible to control infectious bovine keratoconjunctivitis.
