1. Detection of potentially pathogenic bacteria on cell phones of hospital and university-based populations in Curitiba, southern Brazil. A cross-sectional study
ABSTRACT BACKGROUND: Cell phones have become indispensable for professional activities, including healthcare. Thus, they are possible sources of bacterial contamination. There is a scarcity of data in the literature regarding identification of risk factors for contamination of cell phones with pathogenic bacteria. OBJECTIVE: To compare the prevalence rat

2. Antibiotic Sensitivity Pattern of Bacterial Isolates in Patients with Chronic Rhinosinusitis in Kaduna, Nigeria
Abstract Introduction A common practice in the management of patients with chronic rhinosinusitis (CRS), the empirical use of antibiotics may contribute to treatment failure and to the development of antimicrobial resistance. Objective To determine the antibiotic sensitivity pattern of aerobic and anaerobic bacteria associated with CRS. Methods This wa

3. Duplex Real-Time PCR Using Sybr Green I for Quantification and Differential Diagnosis between Salmonella Enteritidis and Salmonella Typhimurium
ABSTRACT The incidence of foodborne diseases caused by the genus Salmonella spp. in industrialized countries is often high in epidemiological surveys. Obtaining a rapid diagnostic test for identification of bacteria is crucial in order to rapidly implement control measures to contain bacterial spread, to reduce losses in animal production and to avoid risks

4. INVESTIGATION OF BIOFILM FORMATION IN COAGULASE-NEGATIVE STAPHYLOCOCCI ISOLATED FROM PLATELET CONCENTRATE BAGS
Platelet Concentrates (PCs) are the blood components with the highest rate of bacterial contamination, and coagulase-negative staphylococci (CoNS) are the most frequently isolated contaminants. This study investigated the biofilm formation of 16 contaminated units out of 691 PCs tested by phenotypic and genotypic methods. Adhesion in Borosilicate Tube (ABT)

5. Validation of a real-time PCR assay for the molecular identification of Mycobacterium tuberculosis
Mycobacterium tuberculosis is the major cause of tuberculosis in humans. This bacillus gained prominence with the occurrence of HIV, presenting itself as an important opportunistic infection associated with acquired immunodeficiency syndrome (AIDS). The current study aimed to develop a real-time PCR using Eva Green technology for molecular identification of

6. Direct detection of Mycobacterium tuberculosis complex in bovine and bubaline tissues through nested-PCR
Post-mortem bacterial culture and specific biochemical tests are currently performed to characterize the etiologic agent of bovine tuberculosis. Cultures take up to 90 days to develop. A diagnosis by molecular tests such as PCR can provide fast and reliable results while significantly decreasing the time of confirmation. In the present study, a nested-PCR sy

7. Comparison of methods for the detection of biofilm formation by Staphylococcus aureus isolated from bovine subclinical mastitis
Biofilm formation is considered to be a selective advantage for Staphylococcus aureus mastitis isolates by facilitating bacterial persistence in the udder. It requires attachment to mammary epithelium, proliferation and accumulation of cells in multilayers. The objective of this study was to determine the sensitivity and specificity of three techniques for t

8. Application of broad-range bacterial PCR amplification and direct sequencing on the diagnosis of neonatal sepsis
A broad-range bacterial PCR target to conserved regions of the 23S rDNA was applied to 306 blood culture samples from 295 infants (up to one year of age) admitted to a neonatal intensive care unit. Classic blood culture results were compared to DNA sequencing analysis of the PCR amplification products. Culture results were in agreement to DNA sequencing in 9

9. Clostridium perfringens isolate typing by multiplex PCR
Clostridium perfringens is an important pathogen that provokes numerous different diseases. This bacterium is classified into five different types, each of which capable of causing a different disease. There are various methods for the bacterial identification, many are labor-intensive, time-consuming, expensive and also present low sensitivity and specifici

10. Ocorrência, identificação e caracterização das espécies de xanthomonas, causadoras de mancha bacteriana em tomate para mesa no Brasil
Tomato bacterial spot is caused by at least four Xanthomonas species (Xanthomonas euvesicatoria, X. vesicatoria, X. perforans and X. gardneri), and is one of the most important diseases of both processing and fresh market tomato crops in Brazil. Eighty one isolates, collected from 23 commercial tomato fields, located in southern, southeastern, central-west a

12. Study of the pneumococcal pneumonia of the childrens hospitalized in the pediatrics ward at the University Hospital of the University of São Paulo / Estudo das pneumonias causadas por Streptococcus pneumoniae em crianças internadas na enfermaria de pediatria do Hospital Universitário da Universidade de São Paulo
Introduction: Currently, the annual incidence of the acquired pneumonia in the developing country communities are around 150.7 million cases, among childrens under 5 years of age, and 11 to 20 million (7-13%) of those require hospitalization due to their gravity. In general, the treatments used to be empirical, however, it is important to be noted that Strep
