One hundred sixty eight bacterial strains, isolated from soil and samples of vegetable in decomposition, were screened for the use citrus pectin as sole carbon source. 102 positive pectinase depolymerization assay plates evidenced by clear hydrolization halos. Among them, 30% presented considerable pectinolytic activity. The cultivation these strains submerged semi-solid fermentation polygalacturonase production indicated that five Bacillus sp produced high quantities enzyme....
An electrochemical genosensor was constructed for detection of specific DNA sequence the hepatitis B virus, based on graphite electrodes modified with poly(4-aminophenol) and incorporating a oligonucleotide probe. The electrode containing probe evaluated by differential pulse voltammetry, before after incubation complementary target. Detection performed monitoring oxidizable bases (direct detection) or using ethidium bromide as indicator hybridization process (indirect detection). device...
Abstract This work describes an electrochemical genosensor for detection of genomic RNA Zika virus in real samples infected patients, using a new platform based on graphite electrodes modified with electrochemically reduced graphene oxide and polytyramine‐conducting polymer. The developed was suitable differentiation between healthy patients by differential pulse voltammetry, detecting up to 0.1 fg/mL (1.72 copies/mL), showing good stability (about 60 days), rapid analysis 20 min) potential...
This was a clinical-epidemiological and mycological study on 184 patients at the university hospital: 200 samples, 142 positive 98 yeasts 68 filamentous fungi. Candida parapsilosis (47%) Trichophyton rubrum (38%) were prevalent. They 100% sensitive to ketoconazole 99% amphotericin B. The highest prevalences among women (80%), adults (62%) toes (84%).
A pandemia da COVID-19 no último ano, compulsou os serviços público e privado a direcionar esforços combate doença, visando à diminuição morbidade letalidade. Assim, o isolamento distanciamento social, foram recomendações ONU para diminuir transmissão suas consequências. Dessa forma, algumas atividades relacionadas vigilância controle leishmaniose visceral (LV), interrompidas drasticamente. Avaliar impacto do período de COVID-19, nas ações programa LV na região São José Rio Preto/SP....
The "In vitro" antifungal activity of ozonized sunflower oil (Bioperoxoil®) was tested on 101 samples yeasts originating from onychomycosis using the disk diffusion method. efficacious against several clinical fungal strains: Candida parapsilosis, albicans, Trichosporonasahii, tropicalis and guilliermondii.
Hepatitis C virus (HCV) is responsible for more than 180 million infections worldwide, and about 80 % of are reported in Low Middle-income countries (LMICs). Therapy based on the administration interferon (INF), ribavirin (RBV) or recently Direct-Acting Antivirals (DAAs). However, amino acid substitutions associated with resistance (RAS) have been extensively described can contribute to treatment failure, diagnosis RAS requires considerable infrastructure, not always locally available. Dried...
Stenotrophomonas maltophilia is a Gram-negative bacillus, which becoming widely recognized as an important nosocomial pathogen. The main objective of this study was to evaluate the genetic relatedness, by random amplified polymorphic DNA (RAPD) and pulsed-field gel electrophoresis (PFGE) 86 clinical isolates S. (colonization 22, infection 64) obtained from 79 hospitalized patients, different geographic regions São Paulo State. genotypic analysis performed RAPD PFGE used in 24 for identity...
In Brazil, few studies on the molecular aspects of hepatitis B virus (HBV) infection have been conducted in interior regions Sao Paulo State. This study aimed to identify HBV genotypes and evaluate strains with resistance mutations for nucleoside analogues Administrative Region (AR) municipality Jose do Rio Preto. We performed nested PCRs 127 samples from Health Care Services AR amplify, sequence analyze fragments DNA, order mutations. The S/Pol 126 were successfully amplified sequenced....
