Evaluation of wound healing and antimicrobial properties of aqueous extract from Bowdichia virgilioides stem barks in mice Anais da ABC (AABC)
AGRA,ISABELA K.R.; PIRES,LUANA L.S.; CARVALHO,PAULO S.M.; SILVA-FILHO,EURÍPEDES A.; SMANIOTTO,SALETE; BARRETO,EMILIANO.
The decoction of the stem barks from Bowdichia virgilioides KUNTH is a folk remedy used to treat inflammatory disorders in Latin American and Brazil. In the present study, the wound healing activity of aqueous extract of the stem bark from B. virgilioides, called AEBv, was evaluated by the rate of healing by wound contraction and period of epithelization at different days post-wound using the wound excisional model. On day 9, the AEBv-treated animals exhibited significative reduction in the wound area when compared with controls. In wound infected with S. aureus, the AEBv significantly improved the wound contraction when compared to the saline-treated mice. The histological analysis showed that AEBv induced a collagen deposition, increase in the fibroblast...

Inactivation of Escherichia coli O157:H7 by essential oil from Cinnamomum zeylanicum BJID
Senhaji,Ouafae; Faid,Mohamed; Kalalou,Ichraq.
Escherichia coli O157:H7 is a pathogen strain, which causes hemorrhagic colitis, hemolytic uremic syndrome and thrombotic thrombocytopenic purpura in humans. The control of bacterial cells in foods is an important factor to reduce foodborne diseases due to E. coli O157:H7. Assays to inactivate E. coli O157:H7 were carried out by using the cinnamon oil obtained by steam distillation for 6 hours. When E. coli O157:H7 cells were incubated at 37°C for 2 hours in the presence of 0.025% of the essential oil from cinnamon, a dramatic decrease was observed in the viable counts (from 10(7) to 3.10(4) CFU/mL-1). In the presence of 0.05% of the oil, most of cells were killed after 30 min, suggesting that the antimicrobial activity of essential oil is bactericidal...

Response of root-knot nematode Meloidogyne javanica to ozone Ciência e Agrotecnologia
Saeedizadeh,Ayatollah; Niasti,Fahimeh; Ameri-Bafghi,Mohammad Esmaeel; Agahi,Kayvan.
ABSTRACT Root-knot nematode, Meloidogyne javanica is a major causal agent of plant diseases on summer crops in fields and greenhouses. In order to reduce environmental concerns, compounds having pesticidal capacity with insignificant residue can be a good alternative to synthetic pesticides. This study was undertaken to investigate the nematicidal capability of ozone under Petri dish (in vitro) and pot (in the rhizosphere of tomato seedlings cv. Super Chief) conditions. The experiments were conducted based on Completely Randomized Design in four replicates with two antimicrobial materials, Cadusafos (0.5, 1.0, 1.5, 2.0, 2.5 and 3 g kg-1 soil) and ozone (0.05, 0.1, 0.2, 0.4, 0.8 and 1.6 g kg-1 soil). Results confirmed the significant in vitro controlling...
