This work was carried outto evalutate the impact of cover crops species in the nutrient eyeling, soil quality, and passion fruit (Passiflora edulis; PF)-productivity. The treinaments consisted of four legumnous species: forage Arachis pintoi, Crotalaria spectabilis, Canavalia ensiformis, Cajanus cajan, cultivated in the interrow area, plus a control treatment (spontaneous species). In the first year, there was a significant effect to the cover crop on PF fruit production and on phosphorus (P), sulphur (S) and copper (Cu) concentration in leaves. The highest fruit production were observed in the A. pintoi and the control treatments. The highets concentration of P was found in PF plants cultivated with C. ensiformis Nevertheless, neither colonisation of plant roots by vesicular-arbuscular mycorrhizal (AM) fungi nor soil phospatase activity, nor soil P content could explain the differences in the P concentration. The cover crop and PF plants increased the number of AM spores in the soil .C.spectabilis negatively affected the S content in PF plants. The fruit production was significantly correlated with the content of S tissue, but not with teh soil sulfatase acitivity. In the control treatment, PF plants accumulated less Cu than with cover crops species. Biochemical parameters such as soil phosphatase and arylsulfatase activities were not significantly different among treatments, which is possibly related to soil fertility. In PF rows, the root-knot nematode Meloidogvne was founde to be mainly associated with the C.spectabilis treatment. However, no negative effects on PF fruit production were associated with the presence of this plant-paratise.

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.
