1. Application of MALDI-TOF MS for requalification of a Candida clinical isolates culture collection
Microbial culture collections underpin biotechnology applications and are important resources for clinical microbiology by supplying reference strains and/or performing microbial identifications as a service. Proteomic profiles by MALDI-TOF MS have been used for Candida spp. identification in clinical laboratories and demonstrated to be a fast and reliable t

2. Search for Mycobacterium leprae in wild mammals
Leprosy is still a worldwide public health problem. Brazil and India show the highest prevalence rates of the disease. Natural infection of armadillos Dasypus novemcinctus with Mycobacterium leprae has been reported in some regions of the United States. Identification of bacilli is difficult, particularly due to its inability to grow in vitro. The use of mol

3. Estudo analitico e olfatometrico de oleo de algodão e oleina de palma utilizados em fritura de produtos carneos / Analytical and olfactometry study of deep-fat frying of meat products, using cottonseed and olein oils
Pretendeu-se através deste estudo levantar dados sobre frituras, em colaboração com agências fiscalizadoras das boas práticas de frituras. Estudou-se o grau de conhecimento de manipuladores de alimentos de 13 estabelecimentos comerciais de Campinas/SP, quanto às boas práticas de frituras, e avaliou-se a qualidade do óleo usado, através de métodos a

4. Use of a molecular tool for the evaluation of Listeria monocytogens in minimally processed vegetable salad. / Emprego de um método molecular para avaliar a presença de Listeria monocytogenes em saladas de hortaliças folhosas minimamente processadas.
The increasing demand for fresh fruits and vegetables, associated with the desire of convenient goodies, is causing an expansion on the market share of minimally processed products (MP). Minimal processing includes operations such as washing, cutting, peeling and packaging of the product. Amongst pathogenic microorganisms that can be transmitted by MP vegeta

5. Use of bar code readers and programmable keypads to improve the speed and accuracy of manual data entry in the clinical microbiology laboratory: experience of two laboratories.
AIM: To assess the effect of the use of bar code readers and programmable keypads for entry of specimen details and results in two microbiology laboratories. METHODS: The solutions selected in each laboratory are described. The benefits resulting from the implementation were measured in two ways. The speed of data entry and error reduction were measured by o

6. Classification and Identification of Enterococci: a Comparative Phenotypic, Genotypic, and Vibrational Spectroscopic Study
Rapid and accurate identification of enterococci at the species level is an essential task in clinical microbiology since these organisms have emerged as one of the leading causes of nosocomial infections worldwide. Vibrational spectroscopic techniques (infrared [IR] and Raman) could provide potential alternatives to conventional typing methods, because they

7. Detection of Pneumocystis carinii by fluorescent-antibody stain using a combination of three monoclonal antibodies.
A combination of three monoclonal antibodies, two prepared against human and one against rat Pneumocystis carinii, was used in an indirect fluorescent-antibody stain (IFA) to diagnose P. carinii in both bronchoalveolar lavage and lung biopsy specimens. This combination of monoclonal antibodies was specific for P. carinii and yielded bright fluorescence of bo

8. Rapid microbial detection and enumeration using gel microdroplets and colorimetric or fluorescence indicator systems.
A new micromethod employing gel microdroplets (GMDs) and optical measurements can be used for rapid detection and enumeration of viable microorganisms (J. C. Weaver, G. B. Williams, A. M. Klibanov, and A. L. Demain, Bio/Technology 6:1084-1089, 1988) and has several potential applications in clinical microbiology. This method involves entrapping microorganism

9. Fast, Noninvasive Method for Molecular Detection and Differentiation of Malassezia Yeast Species on Human Skin and Application of the Method to Dandruff Microbiology
Malassezia fungi have been the suspected cause of dandruff for more than a century. Previously referred to as Pityrosporum ovale, Pityrosporum orbiculare, or Malassezia, these fungi are now known to consist of at least seven Malassezia species. Each species has a specific ecological niche, as well as specific biochemical and genetic characteristics. Malassez

10. Diagnostics of Neisseriaceae and Moraxellaceae by Ribosomal DNA Sequencing: Ribosomal Differentiation of Medical Microorganisms
Fast and reliable identification of microbial isolates is a fundamental goal of clinical microbiology. However, in the case of some fastidious gram-negative bacterial species, classical phenotype identification based on either metabolic, enzymatic, or serological methods is difficult, time-consuming, and/or inadequate. 16S or 23S ribosomal DNA (rDNA) bacteri
