1. Antibacterial efficacy of nisin, bacteriophage P100 and sodium lactate against Listeria monocytogenes in ready-to-eat sliced pork ham
ABSTRACT The effectiveness of bacteriophage P100, nisin and sodium lactate, individually and in combination, in inhibiting Listeria monocytogenes in ready-to-eat pork ham slices was assessed. The antimicrobials were applied to the surfaces of ready-to-eat pork ham slices, which were inoculated with a mixture of L. monocytogenes. Among the individual antimicr

2. Multiplexed reverse transcription real-time polymerase chain reaction for simultaneous detection of Mayaro, Oropouche, and Oropouche-like viruses
ABSTRACT We describe a sensitive method for simultaneous detection of Oropouche and Oropouche-like viruses carrying the Oropouche S segment, as well as the Mayaro virus, using a multiplexed one-step reverse transcription real-time polymerase chain reaction (RT-qPCR). A chimeric plasmid containing both Mayaro and Oropouche targets was designed and evaluated f

3. Internal control for real-time polymerase chain reaction based on MS2 bacteriophage for RNA viruses diagnostics
BACKGROUND Real-time reverse transcription polymerase chain reaction (RT-PCR) is routinely used to detect viral infections. In Brazil, it is mandatory the use of nucleic acid tests to detect hepatitis C virus (HCV), hepatitis B virus and human immunodeficiency virus in blood banks because of the immunological window. The use of an internal control (IC) is

4. In-Vitro Adhesion and Invasion Properties of Salmonella Typhimurium Competing with Bacteriophage in Epithelial Cells and Chicken Macrophages
ABSTRACT This study was designed to assess the role of bacteriophage P22 in the adhesion, invasion, intracellular survival of, and cellular immune response to Salmonella Typhimurium in intestinal epithelial INT-407 and chicken macrophage-like HD11 cells. The ability of S. Typhimurium to adhere, invade, and survive to INT-407 and HD11cells was evaluated under

5. Isolation of
Dickeya dadantii strains from potato disease and biocontrol by their bacteriophagesOne of the most economically important bacterial pathogens of plants and plant products is
Dickeya dadantii . This bacterium causes soft rot disease in tubers and other parts of the potato and other plants of theSolanaceae family. The application of restricted host range bacteriophages as biocontrol agents has recently gaBraz. J. Microbiol.. Publicado em: 21/07/2015

6. Effects of Lactobacillus Probiotic, P22 Bacteriophage and Salmonella Typhimurium on the Heterophilic Burst Activity of Broiler Chickens
Due to the constant evolution of industrial poultry production and the global emergence of bacterial resistance to antibiotics there has been an increasing interest in alternatives for the treatment of poultry salmonellosis, such as phage therapy and probiotics. The present study evaluated the effects of the oral administration of the bacteriophage P22 and o

7. Control of Listeria monocytogenes growth in soft cheeses by bacteriophage P100
The purpose of this study was to determine the effect of bacteriophage P100 on strains of Listeria monocytogenes in artificially inoculated soft cheeses. A mix of L. monocytogenes 1/2a and Scott A was inoculated in Minas Frescal and Coalho cheeses (approximately 10(5) cfu/g) with the bacteriophage added thereafter (8.3 x 10(7) PFU/g). Samples were analyzed i

8. The efficiency of concentration methods used to detect enteric viruses in anaerobically digested sludge
The presence of enteric viruses in biosolids can be underestimated due to the inefficient methods (mainly molecular methods) used to recover the viruses from these matrices. Therefore, the goal of this study was to evaluate the different methods used to recover adenoviruses (AdV), rotavirus species A (RVA), norovirus genogroup II (NoV GII) and the hepatitis

9. Bacteriophage amplification assay for detection of Listeria spp. using virucidal laser treatment
A protocol for the bacteriophage amplification technique was developed for quantitative detection of viable Listeria monocytogenes cells using the A511 listeriophage with plaque formation as the end-point assay. Laser and toluidine blue O (TBO) were employed as selective virucidal treatment for destruction of exogenous bacteriophage. Laser and TBO can bring

10. Fibroblastos gengivais humanos em co-cultura com Aggregatibacter actinomycetemcomitans lisogênico induzem a liberação de fago / Human gingival fibroblasts in co-culture with Aggregatibacter actinomycetemcomitans lysogenic induces the release of phage
A relação entre bacteriófagos e virulência bacteriana é um modelo muito intrigante e pouco estudado na patogênese periodontal, uma vez que um patógeno periodontal pode ser lisogênico. O objetivo do nosso estudo é determinar a capacidade de fibroblastos gengivais humanos de induzir as cepas lisogênicas de Aggregatibacter actinomycetemcomitans. Dois

11. Isolamento, caracterização e uso de bacteriófagos no biocontrole de Salmonella Typhimurium / Isolation, characterization and use of bacteriophage in biocontrol of Salmonella Typhimurium
O Brasil é o quarto maior produtor e quinto maior consumidor mundial de carne suína. Sua cadeia produtiva está em constante evolução a fim de fornecer produtos de qualidade tanto para o mercado interno quanto externo. Entretanto a presença de Salmonella em praticamente todas as etapas de produção constitui um problema de saúde pública e de grande p

12. Listeria monocytogenes em linguiças do tipo frescal vendidas a varejo no município de Salvador-BA e eficácia do bacteriófago P100 no controle da contaminação pelo patógeno.
The outbreaks of Food-borne Diseases are a reason of concern for the food industries and public health organs. Listeria monocytogenes is known as an important pathogen causing diseases transmitted by food and its importance has been growing since the 1980s. Although the number of disease cases per year is relatively low, the infection can be serious, with le
