| L'eau qui alimente des structures d’élevage ou encore des plateformes expérimentales aquacoles (et potentiellement l’eau qui en est issue) peut être contaminée par des agents pathogènes infectant les coquillages, et plus particulièrement les huîtres, ou encore par des agents pathogènes entériques représentant un risque pour les consommateurs. Par ailleurs, la production possible d'huîtres tétraploïdes dans les installations d’élevage implique l’étude de solutions de traitement adaptées pour éviter tout rejet de gamètes, larves ou naissain d’animaux polyploïdes dans l'environnement. Le projet DESIMER a donc pour objectif d’étudier et de comparer différentes techniques de désinfection de l’eau de mer : la chloration, l’ozonation et le rayonnement UV afin de... |

| El chile piquín es una planta silvestre que presenta ciertos mecanismos para asegurar la perpetuación de la especie. Dentro de estos mecanismos se encuentra la latencia de sus semillas. La germinación de las semillas de chile piquín presenta problemas para siembras intensivas comerciales. En este trabajo se planteó: 1) comparar diversas colectas en cuanto a su capacidad germinativa; 2) indagar si la baja germinación se debe a impermeabilidad en la semilla o a alguna característica estructural de la semilla; 3) encontrar un tratamiento de preacondicionamiento que mejore la germinación de la semilla y 4) probar la germinación in vitro como un método alternativo para obtener plántula en un corto tiempo. Para prevenir la interferencia de microorganismos... |

| Currently, hospital infection is a serious public health problem, and several factors may influence the occurrence of these infections, including the presence of insects, which are carriers of multidrug-resistant bacterial species. The aim of this study was to isolate staphylococci carried by insects in two public hospitals of Vitoria da Conquista, Bahia and to identify the resistance profile, pathogenicity and efficacy of disinfection of the premises. A total of 91 insects were collected in 21 strategic points of these hospitals, and 32 isolated strains ofStaphylococcus aureus were isolated. Based on antibiogram and Minimum Inhibitory Concentration results, 95% of these strains were susceptible to oxacillin. These strains were also evaluated for the... |

| Formaldehyde was used to disinfect Artemia cysts and nauplii, while introducing two probiotics in the enrichment process: Bactocell (Pediococcus acidilactici) and Levucell (Saccharomyces cerevisiae). The disinfectant was selected due to its potential compatibility with probiotics, since it was more effective against Gram-negative bacteria than against lactic acid bacteria and yeast. However, the presence of formaldehyde reduced the intake of P. acidilactici in Artemia. Consequently, the disinfection was stopped before Bactocell supplementation to the nauplii fed to pollack (Pollachius pollachius) larvae. The mean weight of pollack was higher with this probiotic treatment. Growth was even better with the combination of Levucell and Bactocell, but the yeast... |

| Few data are available in the literature concerning the efficacy of standard hysteroscope disinfection procedures to prevent hepatitis B transmission. The aim of the present study was to determine the risk of hepatitis B virus (HBV) transmission during hysteroscopy among anti-HBc-seropositive women. Serum and hysteroscopic samples were collected from 62 women after diagnostic hysteroscopy. All samples were tested for serologic HBV markers. Polymerase chain reactions (PCR) were carried out to amplify regions C and S of the viral genome and only samples amplified by both pairs of primers were considered to be positive. Anti-HBc was repeatedly reactive in 48 (77%) of 62 serum samples, and HBsAg was detected in 8 (13%). At least one HBV serologic marker was... |

| The effect of bacterial strains on the growth rate of rotifers, Brachionus plicatilis, was determined under monoxenic conditions. The first objective was to obtain sterile rotifer cultures starting from rotifer resting eggs using merthiolate or glutaraldehyde as disinfectant. Sterile rotifer cultures were obtained, without affecting the hatching ability of the resting eggs, when 0.05 µl/l glutaraldehyde was used. This disinfection procedure was used to examine the effect of 20 bacterial strains, isolated from well-performing live-feed production systems, on the population growth rate of rotifers cultured under monoxenic conditions. Five out of the 20 bacterial strains tested were able to improve significantly the asexual reproduction of rotifers. The... |

| This study describes the isolation of S. schenckii in hospital and home environments in Brazil. Samples were collected from surfaces of a veterinary service place and at home. S. schenckii was detected in 1.5% of the samples from the hospital environment. However, this fungus was isolated from all sampled areas in home environments. The isolation of S. schenckii deonstrates that these surfaces could act as infection sources to anials and huans. Therefore, employees and pet owners could be exposed to this agent, and the contamination, through surfaces, could occur through the traumatic inoculation of the fungus or by direct contact with pre-existing lesions. |

| ABSTRACT This experiment was carried out to determine the effects of using garlic extract (Allium sativum) as an alternative to formaldehyde for the disinfection of hatching eggs on hatching traits and growth performance of quails. Four treatments, with 240 hatching eggs each, were evaluated: egg immersion in two different levels (2.5% and 5.0%) of garlic extract (garlic-1, garlic-2), formaldehyde fumigation (positive control), and eggs not submitted to disinfection (negative control). Mid-term and late embryomortality, pipped egg, and culled chick rates were not influenced by the (p>0.05). The highest (p<0.05) early embryo mortality rate was detected in the formaldehyde treatment (9.99%), and the lowest in garlic-2 treatment (2.68%). Hatchability of... |
