| Lactobacillus spp. were identified in 100 broiler litter samples collected from different poultry-rearing regions in Brazil. Ten different Lactobacillus species were identified: L. plantarum, L.casei subsp. pesudoplantarum, L. delbrueckii subsp. delbrueckii, L. reuteri, L. murinus, L. agilis, L. delbrueckii subsp. lactis, L. salivarus subsp. salicinus, L. viridenscens and L. amylophilus. |

| Three hundred and fifty strains of E. coli isolated from septicemic poultry from seven states of Brazil were examined for presence of nine adhesion-encoding genes, hemagglutination and adherence to chicken tracheal cells (in vitro). Analysis of the strains by colony hybridization tests demonstrated that 93.7% of the isolates were fim +, 17% pap+ and 5.7% were sfa+. The mannose sensitive fimbriae occur with similar frequency in APEC isolated from all Brazilians states, while significant differences among pap and sfa genes distributions were observed. The results showed that 0.85% and 0.28% of APEC were positive for genes that encoded enteroaggregative adhesins and EPEC adherence factor, respectively. None of APEC was positive for DA, afa, Bfp and Eae... |

| 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... |
