| Abstract The aim of this study was evaluated the biofilm formation by Staphylococcus aureus 4E and Salmonella spp. under mono and dual-species biofilms, onto stainless steel 316 (SS) and polypropylene B (PP), and their sensitivity to cetrimonium bromide, peracetic acid and sodium hypochlorite. The biofilms were developed by immersion of the surfaces in TSB by 10 d at 37 °C. The results showed that in monospecies biofilms the type of surface not affected the cellular density (p > 0.05). However, in dual-species biofilms on PP the adhesion of Salmonella spp. was favored, 7.61 ± 0.13 Log10 CFU/cm2, compared with monospecies biofilms onto the same surface, 5.91 ± 0.44 Log10 CFU/cm2 (p < 0.05). The mono and dual-species biofilms were subjected to... |

| ABSTRACT Using disinfectants in poultry houses is a common practice to ban the zoonotic pathogens like Salmonella. A major concern in using disinfectants is the emergence of bacteria strains that resist some disinfectants. This phenomenon is manifested in the resistance of some Salmonella serotypes against quaternary ammonium compounds. Such resistance is attributed to qacEΔ1 gene which may be possessed by some Salmonella serotypes. This work aimed to evaluate the resistance of Salmonella serotypes (S. Typhimurium, S. Infantis and S. Entiridis) against different disinfectants (benzalkonium chloride, iodine, gluteraldehyde and hydrogen peroxide). The effect of the disinfectants were evaluated by treatment of the bacteria with different concentrations... |

| Increasing development of aquaculture business has thrown up new requirements in terms of prevention and control of mollusc diseases. In closed structures, one way to reduce infectious risk is to make use of anti-infectives . Specific drugs like antibiotics should be used only for therapeutic purpose against identified agents. Less specific anti-infectives like disinfectants could be employed for preventive and also for curative goals against causal pathogens and opportunist agents. A critical analysis synthesizes the bibliography available on disinfection in mollusc hatcheries and nurseries. Physical and chemical tools are reviewed then selected depending on four criteria: (1) efficiency against most important pathogens of molluscs, (2) safety for... |

| The threat to public health represented by Salmonella is at least partially a consequence of its ecology in poultry hosts. Good manufacturing practices in the processing plant can reduce the contamination of poultry products, and critical control point principles are essential throughout the chain production. One procedure adopted in critical points control to prevent and to reduce Salmonella in farms and poultry products is the use of disinfectants. This study aimed at evaluating disinfectant efficiency against Salmonella enteritidis samples isolated from broiler carcasses in Rio Grande do Sul State between 1995 and 1996. The tested disinfectants were: phenol 1:256, quaternary ammonium 1:2500, glutaraldehyde 1:200, and iodine 1:500, with contact times of... |

| ABSTRACT The objective of this study was to investigate the influence of two cleaning and disinfection programs on broiler performance and on the microbiological status of the facilities. This trial was an observational study of comparative character. Two experiments were conducted, with 960 birds each. Both experiments were carried out in a positive-pressure broiler house. Broilers were distributed in pens equipped with a bell drinker and a tube feeder each. In the first experiment, new wood shavings were used as litter material, and in the second, reused wood shavings were used. Two treatments with16 replicates of 30 birds each were evaluated. The regular treatment consisted of dry and wet organic matter removal, followed by washing. The European... |
