13. Salmonella Panama: Genetic Diversity of the Isolates Collected from Human and Non-human Sources
Abstract INTRODUCTION Salmonella enterica serovar Panama belongs to the D1 serogroup and is frequently associated with nontyphoidal salmonellosis in humans. This study aimed to characterize isolates collected from Northeast Brazil by phenotypic and molecular methods. METHODS Forty four S. Panama strains were examined for antimicrobial susceptibility, viru

14. Diversity of metallo-β-lactamase-encoding genes found in distinct species of Acinetobacter isolated from the Brazilian Amazon Region
BACKGROUND The multidrug resistance (MDR) phenotype is frequently observed in Acinetobacter baumannii, the most clinically relevant pathogenic species of its genus; recently, other species belonging to the A. calcoaceticus-A. baumannii complex have emerged as important MDR nosocomial pathogens. OBJECTIVES The present study aimed to verify the occurrence

15. Non-clonal occurrence of pmrB mutations associated with polymyxin resistance in carbapenem-resistant Klebsiella pneumoniae in Brazil
BACKGROUND Polymyxins are currently used as a “last-line” treatment for multidrug-resistant Gram-negative infections. OBJECTIVES To identify the major mechanisms of resistance to polymyxin and compare the genetic similarity between multi-drug resistant Klebsiella pneumoniae strains recovered from inpatients of public hospitals in the Mid-West of Braz

16. Staphylococcus aureus in tonsils of patients with recurrent tonsillitis: prevalence, susceptibility profile, and genotypic characterization
ABSTRACT Introduction: Bacterial tonsillitis is an upper respiratory tract infection that occurs primarily in children and adolescents. Staphylococcus aureus is one of the most frequent pathogens in the etiology of tonsillitis and its relevance is due to its antimicrobial resistance and persistence in the internal tissues of the tonsils. Tonsillectomy is in

18. Avaliação do potencial antioxidante de proteínas do soro de leite concentradas por ultrafiltração e hidrolisadas por diferentes proteases comerciais
Resumo O objetivo do trabalho foi avaliar as atividades antioxidante e antimicrobiana de hidrolisados proteicos de soro de leite obtidos por diferentes proteases (Alcalase e Flavourzyme) e sua mistura (proporção 50:50). Previamente à hidrólise enzimática, o soro de leite foi concentrado por ultrafiltração com membranas cerâmicas tubulares. A reaçã

19. Antibacterial, anti fungal and E. coli DNA cleavage of Euphorbia prostrata and Pelargonium graveolens extract and their combination with novel nanoparticles
As there are a lot of antibacterial and anti-fungal resistant pathogens, researchers attempt to substitute antimicrobial drugs with various medical plants and novel nanoparticles. The present study was conducted to characterize antimicrobial activities of Euphorbia prostrata and Pelargonium graveolens extract alone and in combination with Mn-Ni@Fe3O4-NPs & M

20. Functional and biological insights of rCollinein-1, a recombinant serine protease from Crotalus durissus collilineatus
ABSTRACT Background: The prevalent class of snake venom serine proteases (SVSP) in Viperidae venoms is the thrombin-like enzymes, which, similarly to human thrombin, convert fibrinogen into insoluble fibrin monomers. However, thrombin-like serine proteases differ from thrombin by being unable to activate factor XIII, thus leading to the formation of loose c

21. Intraocular pressure in subjects with beta-thalassemia minor
RESUMO Objetivo: Beta-talassemia menor é uma doença hereditária comum no sangue em países mediterrâneos como a Turquia e está associada à resistência à insulina. A resistência à insulina por sua vez, pode estar associada à pressão intraocular excessivamente alta e, portanto à cegueira induzida pela pressão intraocular. Este estudo teve como o

22. Kinetic investigations and stability studies of two Bothrops L-amino acid oxidases
Abstract Background: L-amino acid oxidases isolated from snake venoms (SV-LAAOs) are enzymes that have great therapeutic potential and are currently being investigated as tools for developing new strategies to treat various diseases, including cancer and bacterial infections. The main objective of this study was to make a brief evaluation of the enzymatic s

23. Characterisation of plasmid-mediated rmtB-1 in Enterobacteriaceae clinical isolates from São Paulo, Brazil
OBJECTIVES The emergence of 16S rRNA methyltranferases (16 RMTAses) has jeopardised the clinical use of aminoglycosides. RmtB is one of the most frequently reported in Gram-negatives worldwide. In this study, we aimed to estimate the frequency of 16S RMTAses encoding genes in Enterobacteriaceae isolated in a three-month period from a tertiary Brazilian hospi

24. Pharmacological characterization of cnidarian extracts from the Caribbean Sea: evaluation of anti-snake venom and antitumor properties
Abstract Background: Cnidarians produce toxins, which are composed of different polypeptides that induce pharmacological effects of biotechnological interest, such as antitumor, antiophidic and anti-clotting activities. This study aimed to evaluate toxicological activities and potential as antitumor and antiophidic agents contained in total extracts from fi
