An investigation of virulence factors of Legionella pneumophila environmental isolates

Braz. j. microbiol; 49 (1), 2018
ABSTRACT Nine Legionella pneumophila strains isolated from cooling towers and a standard strain (L. pneumophila serogroup 1, ATCC 33152, Philadelphia 1) were analyzed and compared in terms of motility, flagella structure, ability to form biofilms, enzymatic activities (hemolysin, nucleases, protease, pho...

Yersinia pestis detection by loop-mediated isothermal amplification combined with magnetic bead capture of DNA

Braz. j. microbiol; 49 (1), 2018
ABSTRACT We developed a loop-mediated isothermal amplification (LAMP) assay for the detection of Y. pestis by targeting the 3a sequence on chromosome. All 11 species of the genus Yersinia were used to evaluate the specificity of LAMP and PCR, demonstrating that the primers had a high level of specificity...

Complete genome sequence of human pathogen Kosakonia cowanii type strain 888-76T

Braz. j. microbiol; 49 (1), 2018
ABSTRACT Kosakonia cowanii type strain 888-76T is a human pathogen which was originally isolated from blood as NIH group 42. In this study, we report the complete genome sequence of K. cowanii 888-76T. 888-76T has 1 chromosome and 2 plasmids with a total genome size of 4,857,567 bp and C+G 56.15%. This g...

Summary Objective: The aim of this study was to assess the efficacy and safety of ceftazidime-avibactam in the treatment of complicated intra-abdominal infections (CIAIs) and complicated urinary tract infections (CUTIs) with meta-analysis method. Method: We included six randomized clinical trials ident...

Prevalence of Methicillin-resistant Staphylococcus aureus in the Surgical Wards of the Port-of-Spain General Hospital, Trinidad and Tobago

West Indian med. j; 67 (1), 2018
ABSTRACT Objective: Methicillin-resistant Staphylococcus aureus (MRSA) is associated with soft tissue infections in surgical patients. In severe cases, it may result in pneumonia, septicaemia and osteomyelitis. Limited data are available with regard to its prevalence and associations in the Caribbean. T...

Impacto das mudanças da microbiologia na peritonite bacteriana espontânea em três diferentes períodos ao longo de 17 anos

Arq. gastroenterol; 55 (1), 2018
ABSTRACT BACKGROUND: Spontaneous bacterial peritonitis is a serious complication in cirrhotic patients, and changes in the microbiological characteristics reported in the last years are impacting the choice of antibiotic used for treatment. OBJECTIVE: The aim of the present study is to evaluate the ch...

Inibidores de bomba protônica aumentam o risco geral de desenvolver infecções bacterianas em pacientes com cirrose

Arq. gastroenterol; 55 (1), 2018
ABSTRACT BACKGROUND: Acid suppression has been associated with adverse events; such as, enteric infections. Proton pump inhibitors (PPI) are frequently prescribed in patients with cirrhosis, but is unclear if PPI are associated with the development of bacterial infections in these patients. OBJECTIVE:...

Maxillary Osteomyelitis by Actinomyces in a Child

ABSTRACT: Actinomycosis is a bacterial infection caused by Actinomyces species, which usually affect the soft tissues of the cervicofacial region of adult males. Clinically, it's characterized by a slow-growing indurated mass, especially in the submandibular area. However, in a few cases, the jaws bones ...

Molecular Typing of Enterococcus faecalis from Persistent Endodontic Infections

ABSTRACT: Molecular techniques that provide valuable information about the epidemiology of oral strains. The purpose of this study was to determine the genetic relatedness of 83 Enterococcus faecalis strains isolated from treated root canals. These strains were obtained from patients who were treated for...
