1. Rapid, specific, and sensitive detection of the ureR_1 gene in Klebsiella pneumoniae by loop-mediated isothermal amplification method
Klebsiella pneumoniae is one of the main pathogenic bacteria that causes nosocomial infections, such as pneumonia, urinary tract infection, and sepsis. Therefore, the rapid and accurate detection of K. pneumoniae is important for the timely treatment of infectious patients. This study aimed to establish a loop-mediated isothermal amplification (LAMP) method

2. Raoultella ornithinolytica Isolation in Cloacal Microbiota of Tinamus solitarius: Preliminary Data
ABSTRACT Raoultella ornithinolytica is a gram-negative aerobic bacterium belonging to Enterobacteriaceae family, an emerging pathogen that causes several pathogenic conditions in man, with little veterinary importance; however, its identification is underestimated by conventional laboratory techniques. The present study reports the identification of R. ornit

3. Next-generation sequencing virulome analysis of a Yersinia enterocolitica subsp. palearctica bioserotype 4/O:3 ST18 isolated from human blood in Brazil
Abstract Yersinia enterocolitica is a widespread Gram-negative bacterium that causes gastrointestinal disease and other clinical manifestations in humans. Potentially pathogenic Y. enterocolitica has been isolated in Brazil, from human, environmental, food, and animal sources. Herein we report a genome sequence of Y. enterocolitica subsp. palearctica strain

4. Methicillin-resistant Staphylococcus aureus in cystic fibrosis patients: do we need to care? A cohort study
ABSTRACT CONTEXT AND OBJECTIVE: The prevalence of a variety of potentially pathogenic microorganisms in cystic fibrosis patients, such as methicillin-resistant Staphylococcus aureus (MRSA), has increased over the past decade. Given the increasing prevalence of MRSA and the few data available in the literature, better understanding of the clinical repercussi

5. Growth, viability and architecture of biofilms of Listeria monocytogenes formed on abiotic surfaces
Abstract The pathogenic bacterium Listeria monocytogenes can persist in food processing plants for many years, even when appropriate hygienic measures are in place, with potential for contaminating ready-to-eat products and, its ability to form biofilms on abiotic surfaces certainly contributes for the environmental persistence. In this research, L. monocyto

6. Symbiont modulates expression of specific gene categories in Angomonas deanei
Trypanosomatids are parasites that cause disease in humans, animals, and plants. Most are non-pathogenic and some harbor a symbiotic bacterium. Endosymbiosis is part of the evolutionary process of vital cell functions such as respiration and photosynthesis. Angomonas deanei is an example of a symbiont-containing trypanosomatid. In this paper, we sought to in

7. Gas Chromatography - Mass Spectrometry Analysis and Antibacterial Activity of Bluish-Green Pigment from Pseudomonas sp. JJTBVK (KF836502)
The present study was conducted for the isolation of potential bacteria from the desert soil, their molecular identification and prediction of restriction sites of the potential isolate using the bioinformatics tools. Production of the metabolites was done by inoculating in nutrient broth of pH 8.6. Metabolite was bluish-green in color; it was extracted and

8. Adhesive and invasive capacities of Edwarsiella tarda isolated from South American sea lion
Edwarsiella tarda is a zoonotic bacterium that can be isolated from humans, animals and the environment. Although E. tarda is primarily considered a fish pathogen, it is the only species of its genus considered to be pathogenic for humans as well. A survey of zoonotic intestinal bacteria in fresh feces from South American sea lions (SASL) Otaria flavescens,

9. Oxidative stress enhances the expression of sulfur assimilation genes: preliminary insights on the Enterococcus faecalis iron-sulfur cluster machinery regulation
The Firmicutes bacteria participate extensively in virulence and pathological processes. Enterococcus faecalis is a commensal microorganism; however, it is also a pathogenic bacterium mainly associated with nosocomial infections in immunocompromised patients. Iron-sulfur [Fe-S] clusters are inorganic prosthetic groups involved in diverse biological processes

10. Characterization of isolates of Ralstonia solanacearum biovar 2, pathogenic to Eucalyptus "urograndis" hybrids
The objective of this study was to characterize isolates of biovar 2 of Ralstonia solanacearum pathogenic to eucalyptus "urograndis" hybrid by means of biochemical tests, as well as evaluation of host range and identification by PCR with primers for species, biovar and phylotype. Carbohydrate utilization assays revealed that the eucalyptus isolates belong to

11. Transmission of Campylobacter coli in chicken embryos
Campylobacter coli is an important species involved in human cases of enteritis, and chickens are carriers of the pathogen mainly in developing country. The current study aimed to evaluate the transmission of C. coli and its pathogenic effects in chicken embryos. Breeder hens were inoculated intra-esophageally with C. coli isolated from chickens, and their e

12. Mecanismos envolvidos com a sobrevivência de Xylella fastidiosa em condições de estresse e efeito de N-Acetil-L-Cisteína em seu biofilme / Mechanisms involved in Xylella fastidiosa survival under stress conditions and effect of N-Acetyl-L-Cysteine on its biofilm
Xylella fastidiosa is a Gram-negative bacterium that causes several diseases in different plant species, including citrus variegated chlorosis (CVC) in sweet orange (Citrus sinensis L. Osbeck), whose economic damage is of millions of dollars annually. The symptoms development has been associated with the blockage of xylem vessels caused by bacterial biofilm
