Abstract Nano-emulsions are promising carriers for antigen delivery. Here, we evaluated the efficacy of a water-oil nano-emulsion containing concentrated, inactivated Clostridium novyi (C. novyi) type B supernatant culture (nano-iCnB) in protecting Swiss mice against lethal dose alpha toxin concentrated extract. Proteins were confirmed nano-iCnB and their stabilities determined according physical parameters such as Zeta Potential (ZP). Biochemical, hematological morphological appearance...
Acinetobacter baumannii is a Gram-negative, immobile, aerobic nosocomial opportunistic coccobacillus that causes pneumonia, septicemia, and urinary tract infections in immunosuppressed patients. There are no commercially available alternative antimicrobials, multi-drug resistance an urgent concern requires emergency measures new therapeutic strategies. This study evaluated multi-drug-resistant A. whole-cell vaccine, inactivated adsorbed on aluminum hydroxide-chitosan (mAhC) matrix, sepsis...
Bacteria responsible for causing infections are common in hospital environments, water, soil, and food products. The infection risk is intensified by the absence of public sanitation, poor quality life, scarcity. These external factors promote dissemination pathogens direct contamination or biofilm formation. In this work, we identified bacterial isolates obtained from intensive care units southern region Tocantins, Brazil. We compared matrix-assisted laser desorption ionization...
Prospecting of new isolates producers pectinolitic enzymes were performed with cultivation substrates rice, soybean and corn bran. Pectinolitic observed in cultures the NFC 1, 2, 4, 5 6 identified as belonging to genus Aspergillus sp. Isolates NFR 2 NFS1 Rhizopus 3 Cladosporium; however, production was not observed. The polygalacturonase (PG) submerged fermentation culture medium proposed (SM) at 28 37°C quantified by agar diffusion spectrophotometric methods. highest PG obtained 28°C...
The fungus Fusarium verticillioides produces fumonisins (FB1 and FB2), characterized by being the most frequently produced molecular forms with greater toxicity. Fumonisin contamination is responsible for substantial losses during meat production chain, so safe levels of these compounds must be determined. study was directed to establish FB1 in poultry production; this purpose, were used COBB 500® birds on experimental lots infected corn 2015/2016 season Brazil. group included 160 animals,...
