| Enterococci resistance to glycopeptides was evaluated em Brazilian poultry fed with feed supplemented with avoparcin as growth promoter. The susceptibility to the glycopeptides avoparcin, teicoplanin and vancomycin was determined for 217 enterococci isolated from cloacal swabs (one swab per bird) in tests and controls groups. Tests group comprised three groups (A, B and C) of Hubbard broiler-chickens 14, 21 and 35 days old, respectively. These birds were from one single farm, with a common feed source supplemented with avoparcin (10 mg/kg of feed). Controls groups (1 and 2) comprised 25 and 42 days old broilers, respectively, obtained from the Faculty of Veterinary Medicines aviary (University of São Paulo) where avoparcin was never used. No glycopeptide... |

| The efficacy of three different types of experimental competitive exclusion (CE-A, CE-B and CE-C) cultures against Salmonella Kedougou (SK) NCTC 12173, resistant to nalidixic-acid resistant (NalR), in one-day-old broiler chicks, in four treatments with three replicates in each treatment, was evaluated. The mean logarithmic counts of Salmonella program of feces were 0.4 L in the group treated with CE-A, derived from the whole cecal contents of an adult bird with a mixture of aerobic and anaerobic bacterial cultures; 1.22 in the group treated with CE-B, containing aerobic bacterial culture; 1.00 in the group treated with CE-C, containing anaerobic bacterial culture; and 6.64 in the control group. The percentage of colonized birds varied from 10% to 26.66% in... |
