Spread of Mycobacterium tuberculosis in Southern Brazilian persons deprived of ...
Busatto, Caroline; Possuelo, Lia Gonçalves; Bierhals, Dienefer; de Oliveira, Carolina Larrosa; de Souza, Mariana Quaresma; Fanfa, DandaraTo evaluate the genetic diversity and clustering rates of M. tuberculosis strains to better understand transmission among persons deprived of liberty (PDL) in Rio Grande do Sul (RS), southern Brazil. This is a cross-sectional study, including strains of M. tuberculosis isolated from PDL, stored at the Central Laboratory of RS, in the period from 2013 to 2018. The molecular characterization was performed using t...
Helicobacter pylori infection and associated factors
Vianna, Júlia Silveira; Ramis, Ivy Bastos; Silva Junior, Lande Vieira da; Halicki, Priscila Cristina Bartolomeu; Gauterio, Thaisa BozzettiBackground and Objectives: Helicobacter pylori is linked to gastroduodenal pathologies. To determine the frequency and potential risk factors of the H. pylori infection. Material and methods: A cross-sectional study was conducted, including 227 patients, submitted to upper gastrointestinal endoscopy. A questionnaire was applied to the patients, before endoscopy. The biopsy specimens were obtained from the antru...
The interplay between mutations in cagA, 23S rRNA, gyrA and drug resistance in ...
Vianna, Júlia Silveira; Ramis, Ivy Bastos; Ramos, Daniela Fernandes; Gastal, Otávio Leite; Silva, Renato Azevedo da; Gonçalves, Carla VitolaIn this study, we evaluated the mutations of Helicobacter pylori associated with resistance to clarithromycin and levofloxacin. Furthermore, based on the proposed interaction between antimicrobial resistance and pathogenicity, we correlated the mutation profiles of the strains with the presence of the pathogenicity gene cagA. We analyzed 80 gastric biopsy specimens from H. pylori-infected patients for point mut...

Volcão, Lisiane Martins; Lacava, Juliano Pereira; Ramis, Ivy Bastos; Ramos, Daniela Fernandes; Damati, Gustavo Souto; Gonçalves, Carla VitolaBackground and Objectives: Fluoroquinolones represent a class of amtimicrobials which isfrequently prescribed for the treatment of urinary tract infections (UTIs) of both hospital and community origin. This study aims, to determine the frequency and the factors associated with resistance to ciprofloxacin and levofloxacin in gram-negative bacilli isolated from patients with UTIs treated in a hospital in southern...
Genotypic analysis of Helicobacter pylori by Multiple-Locus Variable-Number Tan...
Halicki, Priscila Cristina Bartolomeu; Ramis, Ivy Bastos; Vianna, Júlia Silveira; Gautério, Thaísa Bozzetti; Groll, Andrea vonBackground and objectives: Despite its use as a genotyping method for different microorganisms, few studies have reported the use of Multiple-Locus Variable Number of Tandem Repeats Analysis (MLVA) for the analysis of the clonal diversity of Helicobacter pylori. The aim of this study was to determine the genetic variability of H. pylori strains by MLVA in southern Brazil. Methods: 95 H. pylori DNA samples were ...
