3. Carbapenem-resistant Acinetobacter baumannii contamination in an intensive care unit
Abstract INTRODUCTION: Acinetobacter baumannii is a major pathogen causing infections in intensive care units (ICUs). In this study, we aimed to evaluate the presence of A. baumannii in an ICU environment and gloves from ICU workers and to characterize the antimicrobial resistance of the isolates in comparison with those isolated from ICU patients at the sa

6. Detection of Streptococcus mutans using padlock probe based on Rolling Circle Amplification (RCA)
The aim of this study was to develop and evaluate a padlock probe based on the Rolling Circle Amplification (RCA), which targeted to 16S-23S rDNA region of S. mutans. The specificity of developed padlock probe was tested for DNA within a panel strains, including S. mutans isolated from the saliva and reference strains of the genus Streptococcus, as well as t

8. Analyses of the 16S-23S intergenic region of the phytoplasma causing the sugarcane white leaf disease in Yunnan Province, China
Sugarcane white leaf (SCWL) is an important disease caused by a phytoplasma. In Baoshan, Yunnan, China, SCWL was firstly observed in 2012, and has extended its area of occurrence to 600 hm² . Up to 52% of the plants may become diseased in a field and even complete loss of cane yield may result in the heavily infected fields, posing a serious threat to Yunna

9. Biological characteristics and probiotic effect of Leuconostoc lactis strain isolated from the intestine of black porgy fish
A strain of lactic acid bacteria, Leuconostoc lactis, was isolated from the intestinal tract of black porgy, Sparus macrocephalus, and identified by conventional biochemical characteristics and 16S rDNA gene sequence analysis. The isolated strain had the ability of bile tolerance and resistance to low pH, and survived well in the trypsinase and pepsin soluti

10. Caracterização taxonômica de espécies do gênero Xanthomonas / Taxonomic characterization of Xanthomonas species
Xanthomonas species are responsible for diseases causing economic losses in many crops. These phytopathogens have been subject of several taxonomic studies resulting in significant changes at interespecific or infraspecific level. This study aimed the taxonomic characterization of Xanthomonas species including: (1) differentiation and phylogenetic analysis o

11. Isolation and characterization of endophytic bacteria isolated from the leaves of the common bean (Phaseolus vulgaris)
The common bean is one of the most important legumes in the human diet, but little is known about the endophytic bacteria associated with the leaves of this plant. The objective of this study was to characterize the culturable endophytic bacteria of common bean (Phaseolus vulgaris. leaves from three different cultivars (Vermelhinho, Talismã, and Ouro Negro)

12. Potential use of molecular-typing methods for the identification and characterization of salmonella enterica serotypes isolated in the poultry production chain
Salmonella is widespread in nature and can be found in all links of the poultry production chain. Due to its high impact on meat processing, techniques for the rapid detection and reproducible characterization of Salmonella serotypes in foods are needed. The present study investigated the potential of molecular profiling to identify and differentiate 15 Salm
