Coronaviruses (CoV) make up a large family of viruses, known since the mid-1960s, which received this name due to spikes on its surface, resemble crown (from Latin corona). CoV infections can cause everything from common cold severe respiratory syndromes, such as acute syndrome (SARS-CoV) and Middle Eastern (MERS-CoV). COVID-19 is new variant coronavirus, isolation occurred in China January 7th, 2020. has stood out with high impact public health number cases infection short period time....

ABSTRACT The presence of Helicobacter DNA species has been investigated in the biliary epithelium patients with diseases. However, conflicting results have observed that may due to small number subjects studied, difficulty obtaining a healthy control group, absence controlling for confounding factors, or differences among populations. Therefore, we by culture and nested PCR 16S rRNA genes gallbladder tissue bile from 46 Brazilian 18 without cholelithiasis. group was mainly composed liver...

ABSTRACT The babA2 and cagA genes were investigated in 208 Brazilian Helicobacter pylori strains. A strong association between duodenal ulcer or gastric carcinoma was observed, even after adjusting for confounding factors, such as age, gender, status. -positive strains also independently associated with H . -related diseases.

Vancomycin-resistant enterococci (VRE) are important hospital pathogens and have become increasingly common in patients admitted to the intensive care unit (ICU). To determine incidence risk factors associated with VRE colonisation among ICU patients, active surveillance cultures for faecal carriages were carried out of University Hospital Uberlândia, Minas Gerais, Brazil. Risk assessed using a case-control study. Seventy-seven (23.1%) found be colonised vanC only one patient (0.3%) was vanA...

Abstract Intraguild predation is a mix of competition and occurs when one species feeds on another that uses similar resources. Theory predicts intraguild hampers coexistence involved, but it common in nature. It has been suggested increasing habitat complexity the presence alternative food may promote coexistence. Reciprocal limits possibilities for even further. Habitat are believed to We investigated this using two predatory mites, Iphiseiodes zuluagai Euseius concordis , by assessing...

Introduction. Vancomycin has become the first-line therapy for most infections caused by methicillin-resistant staphylococci.Aim. To evaluate vancomycin MIC, staphylococcal cassette chromosome mec (SCCmec) types and clonality of coagulase-negative staphylococci (CoNS) isolates recovered from neonates with true primary bloodstream (BSI).Methodology.

Therefore, we prospectively investigated the presence of intestinal mucosa patients without Crohn's by culture polymerase chain reaction (PCR) assays. Materials Methods: Mucosal fragments were obtained from ileum, different colon regions, rectum 43 74 disease. Results: pylori strains, identified 16S rRNA gene sequencing, more frequently isolated PCR‐detected ulcerative...

The pathogens associated with ants at the teaching hospital of Federal University Triângulo Mineiro, in Uberaba, MG, were studied. Three species identified: Tapinoma melanocephalum, Pheidole sp and Paratrechina longicornis. principal microorganisms found Staphylococcus sp, Gram-positive bacilli, Pseudomonas Micrococcus sp. results from collections analyzed according to number colonies different isolated, using Student's t test. statistical analysis showed that there was a significant...

INTRODUCTION: In the past two decades members of genus Enterococcus have emerged as important nosocomial pathogens worldwide. This study prospectively analyzed distribution species and trends in antimicrobial resistance among clinical isolates enterococci a Brazilian tertiary hospital from 2006-2009. METHODS: Enterococcal were identified by conventional biochemical tests. The susceptibility profile was performed disk diffusion accordance with Clinical Laboratory Standards Institute (CLSI). A...

Biofilm formation is a key factor in the pathogenesis of enterococcal infections. Thus, biofilm-forming ability and frequency biofilm-related genes penicillin-resistant, ampicillin-susceptible Enterococcus faecalis (PRASEF) compared to penicillin- E. (PSASEF) were assessed present study. In addition, effect sub-inhibitory concentrations (sub-MICs) antibiotics on biofilm expression virulence was evaluated. Twenty PRASEF 21 PSASEF clinical isolates used determine sub-MICs (ampicillin,...

ABSTRACT In a search for Helicobacter species in the intestinal mucosae of 42 patients with ulcerative colitis (UC) and 74 without UC, only H. pylori was found. Although bacterium detected UC by culture (7.1%) nested PCR (19.0%), its presence not associated disease ( P = 0.13).

Polymorphisms in genes linked to the innate and adaptive immune response may be involved inflammatory bowel disease pathogenesis. Our aim was investigate associations among IL1B-511, IL1B-31, IL1RN, TNFA-307, TLR-2, TLR-4, IL2-330, NOD2 G908R, L1007fsinsC polymorphisms both Crohn's (CD) ulcerative colitis (UC) a Brazilian population.We studied 43 patients with CD, 42 UC, 541 blood donors. were evaluated by PCR, PCR-CTPP, or PCR-RFLP. Data analyzed multivariate models adjusting for...

In this study, genotyping techniques including staphylococcal chromosomal cassette mec (SCCmec) typing, pulsed-field gel electrophoresis (PFGE), multilocus sequence typing (MLST) and restriction-modification tests were used to compare the molecular characteristics of methicillin-resistant Staphylococcus aureus (MRSA) isolates recovered at two times within a 10-year interval (1998 2008) from tertiary Brazilian hospital. addition, antimicrobial susceptibility profiles analyzed. All 48 MRSA...

Introduction Insects have been described as mechanical vectors of nosocomial infections. Methods Non-biting flying insects were collected inside a pediatric ward and neonatal-intensive care unit (ICU) Brazilian tertiary hospital. Results Most (86.4%) them found to carry one or more species bacteria on their external surfaces. The isolated Gram-positive bacilli (68.2%) cocci (40.9%), Gram-negative (18.2%). Conclusions hospital carrying pathogenic bacteria; therefore, must consider the...

The aim of the present study was to verify whether penicillin-resistant, ampicillin-susceptible Enterococcus faecalis (PRASEF) occurred in Brazil prior beginning 21st century, and ampicillin susceptibility can predict other β-lactams E. with this inconsistent phenotype. presence polymorphisms pbp4 gene genetic diversity among isolates were investigated. Of 21 PRASEF analyzed, 5 (23.8%) 4 (19.0%) imipenem piperacillin resistant simultaneously by disk diffusion broth dilution respectively,...
