| The heteroantagonism between Enterobacter agglomerans, isolated from the gastrointestinal tract of American vulture Coragyps atratus, and Pseudomonas aeruginosa isolated from a hospital environment was evaluated. The slow (layer) and the wells (direct) techniques were tested, using agar and soy tryptone broth pH 7.3 at 37ºC. Through the slow method from 196 tests, inhibition growth halos, related heteroantagonism phenomenon observed in 118, corresponding to 60.2% positive results. Equivalent positive results were detected using wells (direct) methodology. The seven samples of E. agglomerans tested were capable of revealing heteroantagonism in the experimental conditions; antagonism reveled by the presence of a clear growth inhibition halo. The added 1%... |

| Em 10 fazendas da região da Serra do Salitre, MG, foram coletadas amostras de leite, soro fermentado (pingo), coalhada e queijo frescal para avaliar a microbiota de bactérias láticas e leveduras presentes. Uma diversidade menor de bactérias láticas foi observada durante a produção do queijo quando comparada à de leveduras. As espécies de bactérias láticas mais freqüentes foram Lactococcus lactis, Enterococcus spp., Enterococcus faecalis e Streptococcus agalactiae e de leveduras foram Debaryomyces hansenii e Kluyveromyces lactis. Apenas as populações de Enterococcus spp., Enterococcus faecalis e Leuconostoc mesenteroides apresentaram aumento significativo durante a produção do queijo. As espécies de bactérias láticas e leveduras encontradas nos diferentes... |

| Myrtaceae is a plant family widely used in folk medicine and Syzygium and Eugenia are among the most important genera. We investigated the anti-allergic properties of an aqueous leaf extract of Syzygium cumini (L.) Skeels (SC). HPLC analysis revealed that hydrolyzable tannins and flavonoids are the major components of the extract. Oral administration of SC (25-100 mg/kg) in Swiss mice (20-25 g; N = 7/group) inhibited paw edema induced by compound 48/80 (50% inhibition, 100 mg/kg; P <= 0.05) and, to a lesser extent, the allergic paw edema (23% inhibition, 100 mg/kg; P <= 0.05). SC treatment also inhibited the edema induced by histamine (58% inhibition; P <= 0.05) and 5-HT (52% inhibition; P <= 0.05) but had no effect on platelet-aggregating... |
