Resumo O uso indevido de antibióticos na produção animal pode exercer pressão seletiva sobre cepas bacterianas, intensificando a disseminação bactérias patogênicas e comensais portadoras genes resistência (GRAs). objetivo deste estudo foi investigar presença GRAs em camas frango provenientes granjas avícolas localizadas no Estado Sergipe, Nordeste do Brasil. Um total 14 amostras cama foram coletadas doze fazendas submetidas à extração DNA total. A testada por Reação Cadeia da Polimerase...
Abstract The misuse of antibiotics in food-producing animal farming practices exerts selective pressure on bacterial strains, intensifying the spread pathogenic and commensal bacteria carrying antibiotic resistance genes (ARGs). We conducted a study aiming to investigate ARGs chicken litter from farms State Sergipe, Northeast Brazil. A total 14 samples were collected twelve subjected DNA extraction. presence obtained material was tested by Polymerase Chain Reaction (PCR) using primers for...
INTRODUCTION: Carbapenem-resistant Klebsiella pneumoniae infection lacks treatment options and is associated with prolonged hospital stays high mortality rates. The production of carbapenemases one the most important factors responsible for this multi-resistance phenomenon. METHODS: In present study, we analyzed presence genes encoding in K. isolates circulating public hospitals city Aracaju, Sergipe, Brazil. We also determined best combination drugs that display vitro antimicrobial synergy....
This study aimed to characterize the chemical diversity of essential oils 37 Croton tetradenius plants grown in municipalities state Sergipe, Brazil, as well evaluate their antibacterial activities. Twenty-five compounds were identified C. tetradenius, and low variation was observed among studied. Monoterpenes, such α-pinene, α-terpinene, p-cymene, 1,8-cineole, trans-pinocarveol, camphor, pinocarvone, cis-ascaridole trans-ascaridole detected major compounds. The Cluster Analysis revealed two...
Evaluate the in vitro efficacy of essential oils derived from Aloysia citrodora (Verbenaceae), Cymbopogon winterianus (Poaceae), and Ocimum gratissimum (Lamiaceae) against Acanthamoeba polyphaga trophozoites. Additionally, microemulsions formulated with these oils, along their major components, were analyzed.
Abstract: The high levels of antibiotic resistance registered worldwide have become a serious health problem, threatening the currently available treatments for series infectious diseases. With antibiotics becoming less and effective, it is increasingly difficult and, in some cases, impossible to treat patients with even common diseases, such as pneumonia. inability meet ever-increasing demand control microbial infection requires both search new antimicrobials improved site-specific...
This study aimed to investigate the effect of pH, temperature, growth atmosphere and nutrient availability on bovicin HC5 production by Streptococcus bovis HC5. S. grew well in complex basal media under aerobic anaerobic conditions, but greater bacteriocin yields were recovered from cultures. Lactate glucose consumption increased if cells cultivated at pH 7.0 45 ºC, higher activity was grown acidic conditions lower temperatures (39 ºC). Cultures maintained continuous CO2 flow showed faster...

<title>Abstract</title> In this manuscript, we describe the effectiveness of crystal proteins from Gram-positive sporulating bacteria against <italic>Acanthamoeba castellanii</italic> trophozoites. Light and scanning electron microscopy were used initially to confirm presence in newly isolated soil bacteria. Toxicity tests conducted using 75 crystal-forming bacterial isolates <italic>A. The MA8, CAB7, AB5 displayed significant antiparasitic activity, with MA8 CAB7 showing IC50 values 4.1 4.3...
Antibiotic resistance is one of the greatest threats to public health in 21st century and presence antibiotic resistant determinants wastewater may reflect current local clinical situation. The objective this study was detect genes (ARGs) Wastewater Treatment Plants (WWTPs) localized Aracaju/SE/Brazil verify role WWTPs limiting spread these contaminants environment. Samples raw treated sewage were collected from four WWTPs, subjected DNA extraction, PCR amplification sequencing ARGs for most...
Introdução: A vigilância em saúde planeja e executa ações que visam a eliminação, controle prevenção dos riscos à cidadãos. Neste contexto, epidemiologia baseada águas residuais promete revolucionar as técnicas de monitoramento doenças através da detecção biomarcadores amostras esgotos, o norteará decisões intervenções imediatas prevenção, tratamento serem implementadas pelos órgãos saúde. Objetivo: Identificar discutir vantagens, desafios contribuições no orientação das pública. Métodos:...
The aim of this study was to undertake a screening experiment on essential oils (EO) Myrcia lundiana, Ocimum basilicum and Lippia alba against six food-spoiling pathogenic bacteria. Seventy-two (72) samples were initially analyzed for antimicrobial activity based the agar diffusion test. minimum inhibitory (MIC) bactericidal (MBC) concentrations determined 12 which showed greatest potential in stage. Two L. alba, three M. lundiana seven O. MIC 0.12-125 μL/mL tested Of these, EO cultivar...
The present study aimed to evaluate the production and factors that influence antimicrobial activity of a bacteriocin-like inhibitory substance (BLIS) produced by Streptococcus equinus C6I9, bovine rumen isolate. antagonist was evaluated spot-on-lawn assay. Antimicrobial crude extracts obtained using NaCl acidic solution (pH 2, 100 mM) along bacterial growth in medium containing different carbon nitrogen sources, agar diffusion method. Crude extract regarding temperature stability, storage...
