Serratia marcescens has emerged as an important opportunistic pathogen responsible for nosocomial and severe infections. Here, we determined phenotypic molecular characteristics of 54 S. isolates obtained from patient samples intensive-care-unit (ICU) neonatal (NIUC) a Brazilian tertiary hospital. All were resistant to beta-lactam group antibiotics, 92.6% (50/54) not susceptible tigecycline. Furthermore, 96.3% showed intrinsic resistance polymyxin E (colistin), last-resort antibiotic the...
Enterobacter cloacae and E. aerogenes have been increasingly reported as important opportunistic pathogens. In this study, a high prevalence of multi-drug resistant isolates from Brazil, harboring several β-lactamase encoding genes was found. Several virulence were observed in aerogenes, contrasting with the which presented none.
Atualmente o exame citopatológico é a principal forma de rastreio para câncer colo uterino, sendo oferecido no Sistema Único Saúde maneira gratuita. Apesar se identificar com gênero masculino, homem transgênero pode ainda possuir órgãos reprodutores femininos, necessária realização deste exame. O estudo teve por objetivo avaliar as dificuldades encontradas homens transexuais acesso ao na Atenção Primária à Saúde. Trata-se uma revisão integrativa da literatura, que permite abordagem ampla...
The aim of this study was to evaluate the antibacterial potential a calcium silicate-based sealer (Bio-C Sealer, Angelus) against common bacteria in primary and secondary endodontic infections. Enterococcus faecalis, Escherichia coli, Pseudomonas aeruginosa, Staphylococcus aureus Streptococcus mutans were exposed fresh Bio-C Sealer for 24 h by agar diffusion method (n=5). Additionally, activity investigated E. faecalis S. biofilms (48 old) grown discs with 4 mm diameter 2 height. (n=3) set...
Klebsiella variicola is mainly associated with opportunistic infections and frequently identified as pneumoniae. This misidentification implies a wrong epidemiology result well incorrect attribution to K. pneumoniae the etiology of some severe infections. Recently, huge efforts have been made study , however, biological aspects this species are still unclear. Here we characterized five strains initially Vitek-2 System 16S rRNA sequencing. One-step multiplex polymerase chain reaction Whole...
The aim of this study was to investigate the blaNDM gene, pathogenic potential, and antimicrobial resistance clinical isolates carbapenem-resistant Klebsiella pneumoniae isolated from patients admitted University Hospital Londrina between January 2014 March 2017.blaNDM-1 virulence genes were investigated using conventional PCR methods Antimicrobial susceptibility testing performed by disk diffusion method according Clinical Laboratory Standards Institute guidelines 2017. Clonal relationships...
Chagas disease is a neglected tropical caused by the parasite Trypanosoma cruzi. Despite efforts and distinct methodologies, search of antigens for diagnosis, vaccine, drug targets still needed. The present study aimed at identifying possible that could be used drugs against T. cruzi using reverse vaccinology molecular docking. genomes 28 strains available in GenBank (NCBI) were to obtain genomic core. Then, subtractive genomics was carried out identify nonhomologous genes host A total 2630...
Emergent hypervirulent Klebsiella pneumoniae has been responsible for severe diseases, representing a serious threat to public health. We report the whole-genome sequencing of novel ST3994-K2 clone, single locus variant ST86 K2, which is considered worrying clone that emerged in several parts world. The strain K. pneumonia Kpi144 was isolated 2013 from blood culture 69-year-old male patient admitted tertiary hospital Teresina, state Piauí, northeastern Brazil. susceptible 41 antibiotics...
Abstract Aim The goal of this study was to standardize a new protocol for collecting biofilm from the interior root canal system (RCS) in vivo testing. Methodology: In study, 44 bovine incisors were used. samples divided into three experimental groups: 14 teeth, 12 counting colony-forming units (CFU), and two scanning electron microscopy (SEM). first group used collection proposed here, second 2nd Biofilm Collection Protocol collection, third with an absorbent paper tip. Two additional teeth...
This study aimed to identify and characterize the antimicrobial susceptibility profile of bacteria found in primary endodontic infections teeth patients treated at Dental Clinic University Ribeirão Preto, São Paulo, Brazil. From September December 2019, samples were obtained from 21 with infections. The collections carried out triplicate using paper cones placed close total length root canal. Bacterial isolation was performed Brain Heart Infusion agar, Blood other selective culture media...
Abstract Recent studies have shown a growing presence of Klebsiella pneumoniae in aquatic environments, raising concerns for fish production due to its resistance many antimicrobials. This bacterium is commonly associated with urinary tract infections, pneumonia, and septicemia humans. Controlling bacterial infectious diseases significant challenge aquaculture. In Brazil, only florfenicol oxytetracycline are approved use this sector. Therefore, study, we assessed the vitro antibacterial...
Abstract Bird drinkers used on poultry farms are highly susceptible to the formation of bacterial biofilms which can cause several diseases for animals and humans. This study evaluated antimicrobial activity new potassium monopersulfate-based products against biofilms. Four named as P.A, P.B, P.C, P.D. developed by Hidrodomi do Brasil industry were evaluated. The tested avian pathogenic Escherichia coli , Salmonella enteritidis Listeria monocytogenes mature To verify products, tests...
Abstract Klebsiella pneumoniae is an opportunistic pathogen that can cause several infections, mainly in hospitalised or immunocompromised individuals. The spread of K. emerging virulent and multidrug-resistant clones a worldwide concern its identification crucial to control these strains especially hospitals. This article reports data related multi-resistant strains, isolated from inpatients the city Manaus, Brazil, harbouring virulence antimicrobial resistance genes, including high-risk...
