Objectives: to carry out the microbiological analysis of drinking taps at a public university in the city of Teresina, Piauí. Methodology: Samples were collected from the faucets of 59 water fountains, inside the campus. Results: The results showed that all drinking water analyzed showed microbial growth, except one. Microorganisms such as Candida sp, Escherichia coli, Salmonella, Shigella, Staphylococcus (including S. aureus) and other enterobacteria were found. In order to verify the antimicrobial activity of S. aureus isolated populations, 5 different antimicrobial types were used, which showed 98% vancomycin resistance and 100% oxacillin resistance. Conclusion: microorganisms found as biofilms in taps are potentially pathogenic, especially S. aureus, which is heavily involved in community and hospital infections. The pattern of antimicrobial resistance found in isolated populations requires further studies and control measures to avoid its propagation.Análise microbiológica das torneiras dos bebedouros de uma universidade pública do estado do Piauí
This study objective was to characterize the hygienic-sanitary profile in ground beef, chilled chicken, ham and sausage manipulated and sold in bulk at supermarket chains in Teresina-PI. Samples of sausage, ham, braised chicken and ground beef sold in bulk were collected at five large supermarket chains in Teresina-PI, identified as SM1, SM2, SM3, SM4 and SM5. Forty samples were analyzed by Faust, Willis and Faust method adapted with alcohol-ether solution in triplicates. Fungus spores, hyphae fragments, eggs (hookworm and Ascaris lumbricoides) and parasite cysts (Entamoeba coli) were found in three of the five supermarket evaluated, as well as many body parts of insects as well as whole insects, these being fleas, mites and ants, in much greater quantities than permitted by law. In two of the five supermarkets chosen for the research no structures were found that could harm human health. It is necessary to implement good hygiene and care practices of meat storage at the analyzed supermarkets and to improve regulatory agencies inspections. In addition, it’s important to promote health education for supermarket workers, in order to avoid food contamination.
O amendoim é uma cultura oleaginosa de grande importância econômica, principalmente para o Estado de São Paulo, onde é cultivado na reforma dos canaviais e são pouco conhecidos os impactos dos herbicidas na cultura. Dentro deste contexto, objetivou-se avaliar os efeitos de diferentes doses de imazapic no controle de eventual comunidade infestante de plantas daninhas, bem como as injúrias provocadas nas plantas de amendoim, cultivar IAC OL3. Utilizou-se o delineamento em blocos casualizados (DBC), com quatro tratamentos e cinco repetições, totalizando 20 unidades experimentais. Os tratamentos foram as doses de imazapic: testemunha; dose de 65 g i.a. ha-1; dose de 98 g i.a. ha-1 e 130 g ia. ha-1. A condição de aplicação foi plante-aplique. Aos 15, 30 e 60 dias após a aplicação (DAA) foram atribuídas notas de controle das plantas daninhas e notas de fitotoxicidade para a cultura do amendoim. Verificou-se controle satisfatório e decrescente das plantas daninhas para todos os tratamentos, exceto para a testemunha até os 60 DAA. As injúrias verificadas desapareceram por completo nas plantas de amendoim aos 75 DAA. Conclui-se que para uma comunidade infestante composta por Cyperus rotundus, Euphorbia heterophilla, Urochloa decumbens e Digitaria insularis, foi controlada com 98 e 130 g imazapic ha-1 em pré-emergência, sem causar danos ao amendoim cultivar IAC OL3.
