1. Microbiological Indicators of Soil Quality Under Native Forests are Influenced by Topographic Factors
Abstract: Several microbiological indicators of soil quality present high sensitivity, but little is known about the influence of topographic factors on them. This work aimed to evaluate variability of biological indicators of soil quality across a hillslope under native forest and the influence of topographic factors on them. Four positions on a hillslope w

3. Investigation of resistance of Salmonella spp. isolated from products and raw material of animal origin (swine and poultry)to antibiotics and disinfectants
RESUMO O gênero Salmonella spp. Possui distribuição geográfica mundial constituindo-se como potencial risco para a saúde animal e saúde humana. O uso inadequado bem como a exposição continuada aos antibióticos e aos desinfetantes pode resultar no surgimento de resistência desses microrganismos frente aos compostos antimicrobianos. Os objetivos do t

4. Acute phase proteins in cats
RESUMO: As proteínas de fase aguda (PFA) são proteínas sintetizadas e libertadas em grande parte por hepatócitos ao mesmo tempo da ocorrência de lesão celular ou invasão por microrganismos. Este artigo revê a utilização das PFA nas doenças do gato identificando a sua potencial utilidade no contexto clínico, analisando 55 artigos publicados. A am

5. Soil Microbial Community Structure and Diversity in Cut Flower Cultures Under Conventional and Ecological Management
ABSTRACT Microorganisms are excellent soil quality indicators because their properties within the soil community change quickly in response to changes in the surrounding environment. The aim of this study was to determine if the structure and diversity of soil bacterial and fungal communities were useful for discriminating cut flower cultures under conventio

6. Self-Monitoring Microbiological Criteria for the Assessment of Hygienic Procedures During Chicken Slaughtering
ABSTRACT Self-monitoring procedures are adopted by food industries to ensure the quality and safety of final products, considering hygiene and processing criteria. This study aimed to evaluate contamination in chicken processing, considering the microbiological criteria proposed by self-monitoring systems. Environmental samples from reception, slaughtering a

7. Evaluation of Petrifilm™ system compared with traditional methodology in count of indicators of sanitary-hygienic quality and pathogenic microorganisms in sheep milk
The objective of this study was to evaluate the applicability of the Petrifilm™ plates to enumerate microbial groups in sheep milk. Samples of sheep milk (n = 30) were plated simultaneously, to enumerate mesophilic aerobes, total coliforms, lactic acid bacteria, Staphylococcus aureus and Escherichia coli, using convencional reference protocols and Petrifil

8. In Vitro antimicrobial photoinactivation with methylene blue in different microorganisms
AIM: To evaluate the in vitro antimicrobial effects of photodynamic therapy (PDT). METHODS: The microorganism indicators were: Candida albicans, Pseudomonas aeruginosa,Enterococcus faecalis and Staphylococcus aureus. A microbial pool was prepared (10 8 cells/mL), from which aliquots were transferred to culture plates for carrying out the PDT using methy

9. Soil health: looking for suitable indicators. What should be considered to assess the effects of use and management on soil health?
Soil Health refers to the ecological equilibrium and the functionality of a soil and its capacity to maintain a well balanced ecosystem with high biodiversity above and below surface, and productivity. To understand and use soil health as a tool for sustainability, physical, chemical, and biological properties must be employed to verify which respond to the

12. Uso de parâmetros microbiológicos como indicadores para avaliar a qualidade do solo e a sustentabilidade dos agroecossistemas.
ABSTRACT: Every factor that has a negative impact on soil microorganisms sooner or later will reflect in a deterioration of soil chemical and physical properties specially, those related to soil organic matter losses. This paper was based on a talk presented at "The International Symposium of Indicators of Soil Quality" held on Marco Juarez-Argentina. Some o
