Avaliação química e microbiológica do capim-elefante, cultivar taiwan A-148, preparado para ensilagem com bagaço de cana-de-açúcar

Elephant grass (Pennisetum purpureum Schum.), was cut after nine weeks of regrowth and mixed with 10, 20, 30 and 40% of sugar cane bagasse (SCB) with the objective of reducing the moisture content of the ensiled mass. Willing of the grass for eight and twelve hours was used as a comparative treatment. Initial dry matter of the grass (13%) increased in the forage mass to 17, 23, 24 and 27% by the addition of 10, 20, 30 and 40% of the SCB respectively. Wilting for eight and twelve hours increased initial dry matter to 18 and 24% respectively. Buffering capacity of elephant grass was reduced by the addition of 40% of SCB. Clostridium spores in the ensiled mass tended to be lower due to the effect of the two pre-treatments. Initial dry matter and number of spores of Clostridium were negatively correlated although without statistic significance. The addition of SCB reduced (P < 0.0.5) soluble carbohydrates and crude protein percentages in the ensiled mass. It was concluded that wilting is more effective than the addition of SCB in the practice of ensiling elephant grass.

Presença de microrganismos na silagem de grãos úmidos de milho ensilado com diferentes proporções de sabugo

This experiment was carried out in the Microbiology Laboratory of UNESP-Jaboticabal, to evaluate the different species of microorganisms in high-moisture corn grain silage. The treatments were five percentages of corn cob in the silage (0, 5, 10, 15 and 20% DM) and four sampling periods after the opening of the silos (0, 2, 4 and 6 days), using a factorial arrangement in randomized block design with three replications. The growth of Lactobacillus was higher (P<0.01) in the silage prepared only with grains in relation to the other treatments. The presence of Clostridium differed (P<0.01) among the treatments, with values ranging from 1.30 and 3.32 log CFU/g of silage. It was concluded that the population of Lactobacillus was satisfactory to obtain a good fermentation of the silages, and the presence of corn cob facilitated the development of Clostridium and also of yeast and Enterobacteriaceae after the silos were opened.

Espectro de agentes etiológicos associados a surtos de doenças transmitidas por alimentos em núcleos receptores turísticos de três regiões geográficas do Estado de São Paulo

Foodborne and waterborne diseases are spread by the consumption of food or water contaminated with bacteria and/or their toxins, viruses, parasites or chemicals. The aim of the research reported here was to establish the spectrum of etiologic agents of foodborne outbreaks at 15 tourist resorts in three geographic regions of the State of Sao Paulo (Brazil). The study was based on the cases reported to the Epidemic Surveillance Center (CVE) of the Public Health Authority of the State of São Paulo (SES), from 2002 to 2005. The tourist centers were chosen at random in three regions of the state (Capital, Interior and Coast) and offered the following attractions: events, agribusiness, cultural history, shopping, town center, gastronomy, health and leisure, sun and sea. Among the bacteria, the results showed that Salmonella spp. were most frequently associated with outbreaks, followed by Shigella spp., enterotoxigenic Escherichia coli, Staphylococcus aureus, Clostridium perfringens, Bacillus cereus and Campylobacter spp. Viruses (Rotavirus and Hepatitis A) played a part in many of the cases, while the frequency of parasites and worm infestations was low in the foodborne disease outbreaks at these resorts. The mixed foods (rice, beans, liver, potatoes, barbecue, juice), fish and poultry were the three commonest vehicles implicated in the outbreaks.
