2. Microbial Communities in Soil Cultivated with Muskmelon under Different Management Systems
ABSTRACT Microorganisms have a fundamental importance in agricultural ecosystems and may be influenced by several factors, including soil management. The aim of this study was to evaluate the effects of cropping systems and soil covers on the microbial community in soil cultivated with muskmelon (Cucumis melo L.). The experiment was conducted in a randomized

3. Mixed biofilms formed by C. albicans and non-albicans species: a study of microbial interactions
Abstract Most Candida infections are related to microbial biofilms often formed by the association of different species. The objective of this study was to evaluate the interactions between Candida albicans and non-albicans species in biofilms formed in vitro. The non-albicans species studied were:Candida tropicalis, Candida glabrata andCandida krusei. Singl

4. Microbial load of reusables trocars after gynecology laparoscopy / Carga microbiana de trocartes reprocessaveis apos laparoscopias ginecologicas
The transmission of hospital infections is related to survival of microorganisms on environmental surfaces and surgical instruments. In recent years, Brazil has been facing a scenario scattered on the validation of cleaning and sterilizing surgical instruments used in minimally invasive procedures performed primarily for video. For implantation of effective

5. Azidiol comprimido como conservante do leite cru destinado a contagem bacteriana por citometria de fluxo.
The objective of the present work was to compare preservative bacteriostatic azidiol in the liquid and compressed forms, sterilized or not for gamma radiation or ethylene oxide, in the preservation of raw milk for the analysis of microbial counting by flow citometry (Bactocount IBC 150®, Bentley Inc.). The results were automatically converted through a curv

6. Profile of antimicrobial resistance of bacteria isolated from cockroaches (Periplaneta americana) in a Brazilian health care institution
Cockroaches carry microorganisms to sterilized materials, equipment and non-contaminated food in hospitals and in homes. Hence, they are regarded as major microbial vectors. We isolated and identified microorganisms from living cockroaches captured from a Brazilian health care institution and we determined the antimicrobial susceptibility profile of the isol

7. "Estudo da microbiota intestinal em doentes com retocolite ulcerativa antes e após retocolectomia com anastomose de bolsa ileal ao canal anal" / Intestinal microbiota in patients with ulcerative colitis, before and after proctocolectomy and ileal pouch-anal anastomosis
Este estudo tem como objetivo, descrever a microbiota intestinal de pacientes com retocolite ulcerativa grave, em tratamento clínico, antes e após retocolectomia com anastomose de bolsa ileal ao canal anal. Comparou-se a flora bacteriana do íleo terminal e do reto no pré-operatório com a flora encontrada na bolsa ileal após dois e oito meses do fechame

8. Development of a drink fermemtada from extract hidrossolúvel of soy, I contend agent probióticos and prebióticos. / Desenvolvimento de uma bebida fermentada a partir de extrato hidrossoluvel de soja, contendo agentes probioticos e prebioticos.
Probiotics and prebiotics are functional and nutraceuticals foods, that contribute to the health and balance of the intestinal tract, reducing the bad absorption of the lactose, increasing the protection against intestinal diseases and so on. Probiotics are live microbial additions to the diet; prebiotics are foodstuffs that have a selective metabolism in th

9. Estudo in vitro da atividade antimicrobiana imediata e mediata da clorexidina gel 2% usada como irrigante endodontico contra Enterococcus faecalis
The initiation and perpetuation of pulpal and periapical disease occur due to the presence of bacteria and their degradatory by products in the root canal. The host defense cells are unable to reach bacteria harbored in the root canal system thus, the root canal therapy must be performed combining mechanical procedures and chemical substances. For that reaso

10. Electrode system for determination of microbial cell populations in polluted water.
Microbial cell populations in polluted water were determined by using a fuel cell-type electrode. The electrode was composed of a Pt anode, a Pt-K3Fe(CN)6-K4Fe(CN)6 cathode, and a cation-exchange membrane for separating two electrode compartments. The principle of microbial cell number determination is based on sensing a redox dye reduced by microorganisms w

11. Improved Aerobic Colony Count Technique for Hydrophobic Grid Membrane Filters
The AOAC International official action procedure for performing aerobic colony counts on hydrophobic grid membrane filters (HGMFs) uses Trypticase soy-fast green FCF agar (FGA) incubated for 48 h. Microbial growths are various shades of green on a pale green background, which can cause problems for automated as well as manual counting. HGMFs which had been i

12. COVASIAM: an Image Analysis Method That Allows Detection of Confluent Microbial Colonies and Colonies of Various Sizes for Automated Counting
In this work we introduce the confluent and various sizes image analysis method (COVASIAM), an automated colony count technique that uses digital imaging technology for detection and separation of confluent microbial colonies and colonies of various sizes growing on petri dishes. The proposed method takes advantage of the optical properties of the surfaces o
