| El principal problema de salud en becerras de reemplazo son las diarreas provocadas por Escherichia coli enterotóxica. El uso de microorganismos pertenecientes al grupo de bacterias ácido lácticas (BAL) en la etapa de lactancia es benéfico para combatir la incidencia de diarreas e incrementar la ganancia de peso. Sin embargo, se ha reportado inconsistencia en los efectos benéficos de los productos comerciales. Por lo anterior, el objetivo de este estudio fue aislar y seleccionar BAL con potencial probiótico de mucosa oral de becerros lactantes, calostro y leche de vacas Holstein que puedan ser consideradas para el suministro de becerras en México. Para ello, se realizó el aislamiento en caldo Man Rogosa Sharp (MRS) y en agar MRS para la obtención de... |

| ABSTRACT The objective of this study was to evaluate the adjustment quality of nonlinear models to data organs growth, carcass and body components of meat-type (Coturnix coturnix coturnix) and japanese laying-type (Coturnix coturnix japonica) quail. A total of 1350 quails from one to 42 d old were distributed in a completely randomized design, with five replicates each. To determine the organs growth (gut, heart, liver and gizzard), carcass and body components (wing, thigh and drumstick, back and breast), two quails per repetition were slaughtered weekly. The data were evaluated in function of different nonlinear models (Logistical, Brody, Richards, Von Bertalanffy and Gompertz). All models studied adjusted the data, differing in adjustment quality. Brody... |

| Avaliou-se o crescimento micelial in vitro das linhagens ABI-05/03, ABI-06/04, ABI-04/02, ABI-06/05 e ABI-01/01 de Agaricus bisporus em meios de cultura sólidos à base de composto. As avaliações foram realizadas por meio de medições de quatro diâmetros das colônias, a cada 48h, durante 12 dias de incubação, no escuro, a 20 e 25ºC. O delineamento experimental foi o de blocos casualizados, com uso do teste de Tukey para a comparação das médias. Com base nos resultados obtidos, verificou-se que: o crescimento micelial de A. bisporus é influenciado pela temperatura de incubação; a temperatura de 25ºC foi mais favorável para o crescimento micelial de todas as linhagens de A. bisporus; na temperatura de 20ºC, o melhor crescimento foi... |

| The mycelium growth kinetics and vigor of shiitake (Lentinula edodes (Berk.) Pegler) strains LE 96/17, LE 98/51, LE 98/53, and LE 98/56 were studied under different agar medium compositions. The strains were from the mycological collection of the Módulo de Cogumelos, Faculdade de Ciências Agronômicas, Unesp-Botucatu, Brazil. Mycelium fragments from stock cultures were transferred to Petri dishes with Sawdust extract-Dextrose-Agar medium. The area of growth and vigor (density) of the mycelia were daily recorded with a digital camera, during incubation, until the complete colonization of the Petri dish. The images were analyzed by the freeware UTHSCSA ImageTool, v. 2.0, developed by the University of Texas Health Science Center, San Antonio. The kinetics of... |

| Two compost formulations based on oat straw (Avena sativa) and brachiaria (Brachiaria sp.) were tested for the cultivation of three Agaricus bisporus strains (ABI-07/06, ABI-05/03, and PB-1). The experimental design was a 2 x 3 factorial scheme (composts x strains) with 6 treatments and 8 repetitions (boxes containing 12 kg of compost). The chemical characterization of the compost (humidity, organic matter, carbon, nitrogen, pH, raw protein, ethereal extract, fibers, ash, cellulose, hemicellulose, and lignin) before and after the cultivation of A. bisporus and the production (basidiomata mass, productivity, and biological efficiency) were evaluated. Data were submitted to variance analysis, and averages were compared by means of the Tukey's test. According... |

| The effect of irradiation doses (0, 125, 250 and 500 Gy) on the nutritional quality of A. bisporus mushrooms (strains ABI-07/06, ABI-05/03 and PB-1) cultivated in composts based on oat straw (Avena sativa) and brachiaria (Brachiaria sp.) was evaluated. The experimental design was 4 x 3 x 2 factorial scheme (irradiation doses x strains x composts), with 24 treatments, consisting of two repetitions each, totaling 48 experimental units (samples of mushrooms). The samples were irradiated in Cobalt-60 irradiator, model Gammacell 220 kGy, with dose rate of 0.740 kGy h–1, according to the treatments proposed. Subsequently, the control (unirradiated) and the other treatments were maintained at 4±1°C and 90% RH in a climatic chamber for carrying out the chemical... |

| Peanut (Arachis hypogaea L.) is an important crop for the family-based systems in the tropics, mainly in Brazil. In the Brazilian drylands, peanuts are cropped in low technological systems, and cheap and efcient technologies are needed to improve crop yield and sustainability. Despite this importance, few data are available on selecting efcient peanut rhizobia in experiments under diferent edaphoclimatic conditions. This work evaluated the agronomic efciency and the biological nitrogen fxation (BNF) by two elite Bradyrhizobium strains under four diferent felds in the Brazilian semiarid region. We compared a new efcient strain Bradyrhizobium sp. ESA 123 with the reference strain B. elkanii SEMIA 6144, currently used in peanut rhizobial inoculants in Brazil.... |

| The aim of this study was to evaluate the productive performance of two strains of Nile tilapia (Oreochromis niloticus) in mixed raising systems. A total of 3600 fish-larvae species was used, 1800 belonging to Bouaké lineage, and 1800 to Chitralada. The experiment was carried out in three phases; Phase I in an incubator in 18 boxes, in which two treatments (Bouaké and Chitralada) were tested by using nine repetitions; Phases II and III were performed in 18 cement tanks with the same treatments. In phase I, regarding the final weight and gain of weight, Chitralada strain showed the highest final weight values. In phase II, Chitralada showed the highest final weight value when compared with Bouaké, and, considering the gain of weight, Bouaké obtained the... |

| The present paper summarizes the serotyping scheme of the fish pathogenic bacterium <i>Vibrio anguillarum</i> and defines seven additional O-serogroups. Strains, collected in our laboratories that were nontypable with antisera against the previously defined 16 O-serotypes, were used for generating new antisera and were characterized further by means of LPS profiles, Western blots, and serological reactions. On the basis of the results, it is suggested that the seven new O-serogroups are to be included in the existing serotyping system as serotypes O17-O<sub>2</sub>3. However, the existence of further <i>V. anguillarum</i> strains that were not typable with any of the 23 O-antisera suggested the existence of additional... |

| In this study, goat fermented milk trials were prepared with six potentially probiotic autochthonous cultures Lactobacillus rhamnosus EM1107, Lactobacillus plantarum (CNPC001, CNPC002, CNPC003 and CNPC004) and Lactobacillus mucosae CNPC007in the presence and absence of a starter culture (Streptococcus thermophilus, ST) and in the presence and absence of inulin (IN) or oligofructose (FOS), consisting of 36 trials. The fermented milk without the starter culture only achieved a lactic acid content above 0.6 g/100 g after 24 h, thus requiring the presence of ST culture for a faster acidification. After the fermentation, three trials with the best fermentative performance and visual firmness (EM1107 + ST + IN, CNPC003 + ST + IN and CNPC007 + ST + IN) were... |

| El objetivo del estudio fue revisar la identificación de dos posibles cepas de Yersinia ruckeri aisladas de diferentes epizootias, diagnosticadas como septicemia bacteriana en 2009 en tilapia cultivada en jaulas, para esclarecer su papel en el cuadro clínico, ya que en los animales afectados no se observaron los signos característicos de la yersiniosis. Se realizó una amplia batería de pruebas bioquímicas mediante técnicas convencionales. La incubación de la motilidad, del Citrato de Simons y del Voges Proskauer, se hizo por duplicado, una réplica se incubó a 25 ºC y la otra, a 37 ºC, lo que permitió identificar a las cepas como Hafnia alvei, que no es un patógeno reconocido de los organismos acuáticos. Se propone un esquema para diferenciar las cepas de... |

| Obtaining uncultured Escherichia coli from natural waters is an important step in the study of microbes in the environment, which are critical for bacterial decay and microbial source tracking. The quality of the samples used can influence the assays, because high contaminant concentrations, differing cell ages, and physiologic states can impair results. The proposed separation is based on a three-step filtration method applied to replicates of seven samples from a sewage plant affluent, collected in different periods. Aliquots of the leachate were inoculated into microcosms, aiming to observe the cultivability of the cells. The assay resulted in colimetry values ranging between 104 and 105 cells. In the leachate, averages of 1.05% of total coliforms and... |
