Patrón EPIYA en cepas de Helicobacter pylori CagA positivas en pacientes del Hospital Regional de Talca

Rev. méd. Maule; 33 (1), 2017
BACKGROUND: The clinical outcome of Helicobacter pylori (H. pylori) infection has been related to the presence of CagA protein. This protein is highly polymorphic and its oncogenic ability depends on the number and type of tyrosine phosphorylation sites in the EPIYAs repeat sequences (A, B, C and D). AIM...

Perfil microbiológico de infecciones urinarias asociadas a cateterismo permanente en el Hospital de Talca

Rev. méd. Maule; 33 (1), 2017
Urinary tract infection associated to permanent catheterization is the most frequent infection associated to health care. Antibiotic resistance is an increasing problem, thus it is important to know the local pathogenic agents, their resistance and sensibility profiles to use an optimal treatment. OBJECT...

Braz. j. infect. dis; 21 (3), 2017

Bartonella species pathogenic for humans infect pets, free-ranging wild mammals and their ectoparasites in the Caatinga biome, Northeastern Brazil: a serological and molecular study

Braz. j. infect. dis; 21 (3), 2017
ABSTRACT This study verified the occurrence of Bartonella spp. in dogs, cats, wild mammals and their ectoparasites in Petrolina and Lagoa Grande Counties, Pernambuco, located in a semi-arid region in Northeastern Brazil. Anti-Bartonella spp. antibodies were detected by indirect immunofluorescence assay (...

Carbapenem-resistant Pseudomonas aeruginosa: association with virulence genes and biofilm formation

Braz. j. microbiol; 48 (2), 2017
Abstract Pseudomonas aeruginosa is an opportunistic pathogen that causes frequently nosocomial infections, currently becoming more difficult to treat due to the various resistance mechanisms and different virulence factors. The purpose of this study was to determine the risk factors independently associa...

Draft genome sequence of a multidrug-resistant beta-lactamase OXA-357-producing Acinetobacter pittii ST865 clinical isolate from China

Braz. j. microbiol; 48 (2), 2017
Abstract Worldwide increasing emergence of carbapenem-resistant Acinetobacter spp. has rendered the limited availability of effective antimicrobial agents and has become a major public health concern. In this study, we report the draft genome sequence of A. pittii TCM156, a multidrug-resistant isolate th...

Dark septate endophyte decreases stress on rice plants

Braz. j. microbiol; 48 (2), 2017
Abstract Abiotic stress is one of the major limiting factors for plant development and productivity, which makes it important to identify microorganisms capable of increasing plant tolerance to stress. Dark septate endophytes can be symbionts of plants. In the present study, we evaluated the ability of d...

Comparison of culture and PCR methods in the diagnosis of bacterial meningitis

Braz. j. microbiol; 48 (2), 2017
Abstract Our aim in this study is to compare the standard culture method with the multiplex PCR and the Speed-Oligo® Bacterial Meningitis Test (SO-BMT) – a hybridization-based molecular test method – during the CSF examination of the patients with the pre-diagnosis of acute bacterial meningi...

Tricalcium phosphate solubilization and nitrogen fixation by newly isolated Aneurinibacillus aneurinilyticus CKMV1 from rhizosphere of Valeriana jatamansi and its growth promotional effect

Braz. j. microbiol; 48 (2), 2017
Abstract Aneurinibacillus aneurinilyticus strain CKMV1 was isolated from rhizosphere of Valeriana jatamansi and possessed multiple plant growth promoting traits like production of phosphate solubilization (260 mg/L), nitrogen fixation (202.91 nmol ethylene mL-1 h-1), indole-3-acetic acid (IAA) (8.1 µg/m...
