Several Cronobacter species are opportunistic pathogens that cause infections in humans. The aim of this study was to detect spp. from 90 samples retail foods Brazil, and characterize the strains by phenotypic tests, molecular assays antibiotic susceptibility. Three isolation methodologies were evaluated using different selective enrichments isolates identified Vitek 2.0, PCRs protocols, fusA allele sequencing multilocus sequence typing (MLST). Thirty-eight (42.2%) contained spp., highest...
Background: Microbial contamination is a significant challenge for the pharmaceutical sector, especially heat-sensitive sterile products. This can alter physical and chemical properties of products, compromising quality safety. Correct bacterial identification essential tracing sources implementing preventive corrective measures. Matrix-Assisted Laser Desorp-tion Ionization-Time Flight/Mass Spectrometry (MALDI-TOF MS) technology has revolutionized microbial identification, but there are...
Bacillus and related genera are among the most important contaminants in pharmaceutical production environment, identification of these microorganisms at species level assists investigation sources contamination preventive corrective decision making. The aim this study was to evaluate three methodologies for characterization endospore-forming aerobic bacterial strains isolated from a unit Rio de Janeiro, Brazil. MALDI-TOF MS performed using MALDI Biotyper® VITEK® RUO systems, complete 16S...
A comercialização de alimentos em um mundo globalizado requer controle sanitário eficaz para garantir seguros. Agência Nacional Vigilância Sanitária (Anvisa) do Brasil estabeleceu critérios a gestão risco nas atividades e fiscalização da importação, que determinam o tipo ser aplicada no desembaraço aduaneiro dos alimentos. Este estudo avaliou robustez das informações relacionadas aos risco. metodologia envolveu uma pesquisa exploratória Portal Anvisa nos sites agências reguladoras Estados...
Abstract This study aimed to assess the microbiological contamination of lettuces commercialized in Rio de Janeiro, Brazil, order investigate detection norovirus genogroup II (NoV GII), Salmonella spp., total and fecal coliforms, such as Escherichia coli . For NoV samples were processed using adsorption‐elution concentration method associated real‐time quantitative polymerase chain reaction (qPCR). A 90 lettuce including 30 whole fresh lettuces, minimally (MP) raw ready‐to‐eat (RTE) salads...
The aim of this study was to determine the prevalence Cronobacter from 30 samples oats and linseeds commercially available in Brazil. detection as according ISO 22964:2017. isolates were characterized their phenotypically using Vitek 2.0 antibiotic susceptibility profile. Molecular characterization accomplished by real-time PCR targeting dnaG gene, rpoB multiplex-PCR cgcA gene fusA allele sequencing. A total 34 (56.7%) contained Cronobacter; 19 (63.3%) 15 (50.0%) oats. identified C....
Characterizing microorganisms according to different criteria is useful when investigating sources of microbiological contamination in the pharmaceutical industry. The aim this study was characterize 38 Acinetobacter baumannii complex strains isolated from a biopharmaceutical industry by 16S rRNA sequencing, matrix-assisted laser desorption ionization-time flight mass spectrometry (MALDI-TOF/MS), multilocus sequence typing (MLST), antimicrobial susceptibility profile, biofilm formation, and...
This study aimed to evaluate the elution-concentration methodology based on skimmed milk flocculation from three varieties of tomatoes (Solanum lycopersicum L. [globe], Solanum var. cerasiforme [cherry] and hybrid cocktail [grape tomato]) for further monitoring field samples. Spiking experiments were performed determine success rate efficiency recovery human norovirus (NoV) genogroup II, murine-1 (MNV-1) used as sample process control virus adenovirus (HAdV). Mean values 18.8%, 2.8% 44.0%...
Microbiological contamination may cause microbial proliferation and consequently additional problems for pharmaceutical companies through production stoppage, product contamination, investigations of process deviations, out-of-specification results disposal. This is one the major concerns regulatory health agencies. load (bioburden) represent a potential risk patients if sterilization not effective and/or due to toxins. Although bioburden can be eliminated by terminal or filtration...
This study aimed to characterize
CONTEXTO: O desenvolvimento de prótese vascular tem sido vital para os avanços e realizações da cirurgia reconstrutora durante as últimas 5 décadas. OBJETIVOS: Desenvolver um novo modelo microperfurada, confeccionada em tecido recoberto com composto derivado do látex natural seringueira (Hevea brasiliensis) avaliar sua perviedade, trombogenicidade, biocompatibilidade o processo cicatrização, além algumas propriedades mecânicas (adaptabilidade, elasticidade, impermeabilidade possibilidade...
O objetivo deste estudo foi avaliar a formação de biofilme e o perfil susceptibilidade antimicrobianos Pseudomonas aeruginosa isoladas na avaliação da qualidade microbiológica 80 amostras águas minerais naturais comercializadas em garrafões 20 L. Foi realizada quantificação P. enterococos; pesquisa coliformes totais, termotolerantes clostrídios sulfito redutores (CSR). A produção avaliada caldo infusão cérebro-coração (BHI) água mineral natural estéril nas temperaturas 25 35ºC por 24 48 h....
