Abstract: Los coliformes fecales son un grupo importante de microorganismos indicadores de inocuidad en alimentos, constituido principalmente por Escherichia coli, el cual es considerado como indicador de contaminación reciente de origen fecal, por ello la importancia de investigar su presencia y determinar rápidamente el nivel poblacional en alimentos. Este trabajo tiene como objetivo comparar el método tradicional Número Más Probable (NMP) para la determinación de coliformes fecales, según Norma Venezolana Covenin No 1104-96 con el método de placas rehidratables PetrifilmTM 3M coliformes incubadas en ba o de agua circulante (PBA) a 45 ± 0,2°C por 24 ± 2 horas y en estufa con aire circulante 44 ± 1°C por 24 ± 2 horas (PES) de acuerdo con lo recomendado por la Asociación Francesa de Normalización (AFNOR) y la Corporación 3M. Se analizaron un total de 42 muestras de queso blanco aplicando ambas metodologías, dispensando simultáneamente diluciones seriadas de las muestras. Para el análisis estadístico se realizó una correlación de muestras relacionadas (SPS versión 7,5), obteniéndose los siguientes resultados r = 0,952 entre NMP y PES y r = 0,944 entre NMP y PBA; lo que indica una buena correlación positiva entre ambas metodologías en sus diferentes modalidades para la determinación de coliformes fecales en muestras de queso blanco. Se concluye que las placas PetrifilmTM coliformes incubadas a la temperatura óptima de crecimiento de dichos microorganismos es un método alternativo, rápido y confiable para la determinación del nivel de coliformes fecales en queso blanco.

Abstract: groups of heterotemies tenuis (hagen, 1858) from five infestation points were paired in bioassays to investigate the intercolony aggression. the combinations of arena sizes (petri dishes of 6.0 and 9.0 cm) and temperatures (25 and 28 oc) were assessed for effects on intraspecific agonism. agonistic behavior was scored positive in arena if more than half of the starting number of termites was dead and injured after 17 hours. after the intraspecific encounters it was possible to delimitate three colonies from the five infestation points. no significant differential survival was seen in two different arena sizes and two different temperatures. these assays indicate that the factors governing the agonistic behavior in h. tenuis are complex and seems to be dependent on environmental conditions and individual characteristies (age, size and caste).

Abstract: Quando as condi es microclimáticas e de transporte s o combinadas inadequadamente, os componentes dos ovos férteis podem ser danificados. Objetivou-se, com este trabalho, caracterizar e analisar a dependência espacial dos perfis microclimáticos no transporte de ovos férteis em diferentes layouts de caixas. A pesquisa foi conduzida na empresa integradora avícola, em Mogi Mirim, SP, por meio do acompanhamento de cinco carregamentos. Utilizou-se um caminh o climatizado do tipo baú, com capacidade para 592 caixas de ovos e se avaliaram dois layouts da carga (caixas superiores e inferiores) de 9 pilhas com seis caixas de ovos férteis. Um microprocessador foi instalado dentro das caixas de ovos, totalizando 18 microprocessadores. As variáveis meteorológicas analisadas foram: temperatura (oC) umidade relativa (%) e entalpia específica (kJ kg-1 ar seco). O delineamento experimental adotado foi o inteiramente casualizado com parcelas subdividas e realizada a análise geoestatística (krigagem ordinária). No layout das caixas superiores foram registrados valores elevados de temperatura e baixos valores de umidade relativa e entalpia específica. As regi es de piores condi es microclimáticas nos dois layouts se situaram nas partes central e traseira do caminh o, durante o transporte dos ovos férteis. The fertile egg components may be damaged when the microclimatic conditions and transportation characteristics are combined inadequately. Thus, the aim of this study was to characterize and to assess the spatial dependence of microclimatic profiles during transport of fertile eggs with different layout of boxes. A trial was conducted in a commercial poultry industry in Mogi Mirim in the State of S o Paulo, Brazil, through monitoring five loads of hatching eggs. An air conditioned truck was used, with maximum capacity of 592 egg boxes. Two layout of boxes were assessed in the present study. One data logger was installed inside the egg boxes, totalizing 18 data loggers. The following thermal variables were studied: dry-bulb temperature (°C), relative humidity (%) and specific enthalpy (kJ kg-1 dry air). A completely randomized design was adopted , with a split-plot structure and was analysed through geostatistics (ordinary kriging). Inside the superior box layout, high values of temperature and lower values of relative humidity and specific enthalpy were registered. The worst regions for microclimatic in both layouts were located in the central and rear part of the truck during transport of fertile eggs.
