Abstract With the arrival of coronavirus disease 2019 (COVID‐19) in Brazil February 2020, several preventive measures were taken by population aiming to avoid severe acute respiratory syndrome 2 (SARS‐CoV‐2) infection including use masks, social distancing, and frequent hand washing then, these may have contributed preventing also other viruses. Our goal was determine frequencies Influenza A B viruses (FLUAV/FLUBV), human mastadenovirus C (HAdV‐C), Enterovirus 68 (EV‐68), rhinovirus (RV)...
Abstract COVID-19 (Coronavirus Disease 2019) outbreak was declared a pandemic, by World Health Organization, on March 11, 2020. Viral detection using RT-qPCR has been among the most important factors helping to control local spread of SARS-CoV-2 and it is considered “gold standard” for diagnosis. Nevertheless, RNA extraction step both laborious expensive, thus hampering diagnosis in many places where there are not laboratory staff funds enough contribute efforts. Thus, need simplify...
The aim of this study was to investigate the presence adenovirus (AdV), rotavirus (RV), and hepatitis E virus (HEV) in beef, pork, chicken meat cuts retail trade city Uruguaiana, RS, Brazil. A total 131 products were collected (beef, n = 55; chicken, 47; 29) from 18 commercial establishments (supermarkets, 7; butchers, markets/grocery stores, 4). All samples evaluated for AdV, RV, HEV. genomes RV AdV identified 29% (n 38) 5.34% 7) samples, respectively. HEV not any samples. Chicken had a...
The objective of this study was to compare HFNC therapy noninvasive ventilation (NIV/BiPAP) in children with bronchiolitis who developed respiratory failure. We hypothesized that would not be inferior NIV.
Summary Mosquito borne flaviviruses cause a series of important diseases in humans and animals. These viruses are maintained cycles involving replication mosquito vertebrate hosts. Most natural hosts animals living sylvatic or peridomestic environments. Human contact with these environments may result host shifts that lead to the establishment urban transmission cycles. Zika virus is Flavivirus persists nature cycle non-human primates (NHP). Its recent emergence Brazil has shed light upon...
ABSTRACT December 2019 marked the begining of greatest pandemic since Spanish Flu, disease named Covid-19 that cause severe pneumonia. Until May 19, 2020 more than 4 million and 700 thousand cases were oficially notified with about 316 deaths. Etiological agent was identified as being a new coronavirus, Severe acute respiratory syndrome-related coronavirus (SARS-CoV-2). In this study we compared four different manual methods for RNA isolation purification detection SARS-CoV-2 through...
Public parks are leisure environments widely used by both, adults and children, often accompained their pets. Soil contamination of these enteric viruses intestinal parasites occurs through animals feces. The aim this work was to detect Carnivore protoparvovirus 1 (CPV-1) different species Mastadenovirus in soils samples from a park located medium-sized city Brazil evaluate the presence helminth eggs larvae 18 points public soil samples, as well feces found on site during six months....
Abstract In this study, serial dilutions of SARS-CoV 2 RNA extract were tested using RT-dPCR three different primer-probe assays aiming nucleocapsid coding region. Narrower confidence intervals, indicating high quantification precision obtained in 100 and 1000-fold dilution results equivalent between the same dilution. High accuracy test allowed conclusions regarding ability technique to evaluate precisely amount genomic copies present a sample. We believe that fast safe method can assist...
Zika virus (ZIKV) is an important arbovirus, responsible for recent outbreaks of Guillain Barré Syndrome and Congenital (CZS). After thousands CZS cases, ZIKV under constant surveillance in Brazil. Reliable robust detection techniques are required to minimize the influence host inhibitors from clinical samples mosquito pool samples. Reverse transcription Digital Polymerase Chain Reaction (RT-dPCR) a technique that allows accurate quantification DNA targets with high sensitivity, it usually...
Abstract Emergence of novel SARS-CoV-2 lineages are under the spotlight media, scientific community and governments. Recent reports variants in United Kingdom, South Africa Brazil (B.1.1.28-E484K) have raised intense interest because a possible higher transmission rate or resistance to vaccines. Nevertheless, spread B.1.1.28 (E484K) other is still unknown. In this work, we investigated population structure genomic complexity Rio Grande do Sul, southernmost state Brazil. Most samples...
Background: Bovine enterovirus (BEV) and bovine adenovirus (BAV) are widely distributed in cattle population, among possible causes of gastroenteritis respiratory disease, respectively, although the infection is more often subclinical. BAV may be also related to conjunctivitis, lead severe infections death immunosuppressive calves. BEV have been associated with disorders reproductive tracts, diarrhea. There little available information about Brazil; however main present study was investigate...
December 2019 marked the beginning of current Coronavirus disease pandemic (COVID-19). Severe acute respiratory syndrome-related coronavirus 2 (SARS-CoV-2) was identified as causative agent a viral pneumonia outbreak in Wuhan, Hubei Province, China. The alarming spread levels and clinical severity elevated status COVID-19 to global by World Health Organization. In 6 months, more than 25 million cases infected people 890,000 deaths had been reported worldwide. main goal this review is shed...
Specific virulence factors that likely influence C. acnes invasion into deep tissues remain to be elucidated. Herein, we describe the frequency of identification in tissue specimens patients undergoing clean shoulder surgery and assess its phenotypic genetic traits associated with antibiotic resistance patterns, compared isolates from skin healthy volunteers. Multiple bone fragments, tendons, bursa 84 otherwise primary clean-open arthroscopic surgeries were aseptically collected. The overall...
The main goal of this study was to apply magnetic bead surface functionalization in the form immunomagnetic separation (IMS) combined with real-time polymerase chain reaction (qPCR) (IMS-qPCR) detect Human mastadenovirus species C (HAdV-C) and F (HAdV-F) water samples. technique efficiency compared a nonfunctionalized method (ultracentrifugation) followed by laboratory detection. Tests were carried out standardize IMS parameters tests on 15 samples concentrated ultracentrifugation....
A diversidade genômica e filogenética de Cutibacterium acnes tem sido identificada como potenciais marcadores patogenicidade. Analisamos os isolados C. obtidos amostras clínicas, para investigar suas características genéticas filotípicas. No total, 11 cepas foram identificados em tecidos profundos (bursa, osso sinóvia) pacientes submetidos a cirurgias limpas primárias ombro que acompanhados prospectivamente por 2 anos. Os técnica sequenciamento genômico completo (WGS) identificar genômicos...
Staphylococcus epidermidis (SEPI) é um agente comensal oportunista predominante na pele com habilidade de formar biofilme, porém comumente associado às Infecções Musculoesqueléticas (IME) ou sem implantes. Neste estudo, buscou-se identificar marcadores fenotípicos e genotípicos que diferenciem as formas patogênicas causadoras IME das comensais da pele. Um total 43 isolados SEPI, provenientes IMEs (n=28) swabs pessoas saudáveis (n=15) foram estudados. O perfil fenotípico foi avaliado por...
