1. Lytic bacteriophages as a potential alternative to control Staphylococcus aureus
Resumo: O objetivo deste trabalho foi caracterizar bacteriófagos autóctones e determinar sua atividade lítica em Staphylococcus aureus. Seis fagos foram isolados de água de lavagem de pisos de estábulos por meio do enriquecimento de cultura com três estirpes de S. aureus. Todos os fagos foram caracterizados pela digestão do DNA com enzimas de restriç

2. Isolamento e caracterização de bacteriófagos líticos de bactérias patogênicas associadas com mastite bovina / Isolation and characterization of lytic bacteriophages for pathogenic bacteria associated with bovine mastitis
A mastite bovina é a principal doença que acomete os rebanhos de gado de leite no Brasil e no mundo, sendo responsável por imensos prejuízos. Diversos microrganismos são causadores da doença, tais como Staphylococcus aureus, Streptococcus agalactiae, Streptococcus dysgalactiae, Streptococcus uberis, Streptococcus epidermidis, Corynebacterium bovis, Cor

3. Avaliação de probiótico e bacteriófagos líticos para o controle de Salmonella sp. em supinos experimentalmente infectados
Devido à limitação do uso de antimicrobianos, alternativas que seguem a linha de controle biológico, como os bacteriófagos líticos e probióticos, vêm sendo propostos para o controle de Salmonella sp. em animais de produção. O objetivo deste estudo foi avaliar o efeito da administração oral de probiótico e bacteriófagos líticos sobre a ocorrên

4. Genomic variants of bacteriophages against Salmonella enterica serovar Enteritidis with potential application in the poultry industry
Salmonella enterica serovar Enteritidis (SE) is a prevalent gastrointestinal pathogen worldwide, threatening both animal and human health. In the latter, disease is associated to the consumption of SE-contaminated products from the poultry industry. The control of SE infection is largely based on the use of antibiotics and vaccines, but the use of lytic bact

5. Levantamento de bacteriofagos liticos : isolamento e caracterização de virus provenientes de esgoto comum com potencial aplicação antimicrobiana / Survey of lytic bacteriophages: isolation and characterizatio of virus proceeding from raw sewage with potential antimicrobial application
Bacteriophages, viruses that infect prokaryotic hosts, are the most numerous biological entities of the world. Their abundance implied in reviews in several areas of knowledge, like genetics, evolution and ecology, and phages are now recognized as important vectors in the flux of matter, energy and information in natural environments. However, there is a hug

6. Use of lytic bacteriophages to reduce Salmonella Enteritidis in experimentally contaminated chicken cuts
Reducing Salmonella contamination in poultry is of major importance to prevent the introduction of this microorganism into the food chain. Salmonellae may spread during storage time (shelf life) whenever pre-harvest control fails or post-harvest contamination occurs. Therefore, preventive measures should also be used in the post-harvest level of poultry prod

7. In vitro characterization and in vivo properties of Salmonellae lytic bacteriophages isolated from free-range layers
Occurrence of food poisoning related to Salmonella-contaminated eggs and chicken meat has been frequent in humans. Salmonella Enteritidis (SE) and Salmonella Typhimurium (ST) are included among the most important paratyphoid salmonellae associated with chicken meat and eggs. Elimination of Salmonella at the pre-harvest stage can play a significant role in pr

10. Alteration of Host Specificity to Lytic Bacteriophages in Streptococcus cremoris†
A mutant of Streptococcus cremoris strain ML1 was isolated based on its resistance to acriflavine. The mutant strain showed resistance to the growth of virulent bacteriophages to which the parental strain was sensitive whereas it became sensitive to a number of other virulent phages to which the parental strain was resistant. At the same time, infection of t

11. Reduction of Experimental Salmonella and Campylobacter Contamination of Chicken Skin by Application of Lytic Bacteriophages
Lytic bacteriophages, applied to chicken skin that had been experimentally contaminated with Salmonella enterica serovar Enteritidis or Campylobacter jejuni at a multiplicity of infection (MOI) of 1, increased in titer and reduced the pathogen numbers by less than 1 log10 unit. Phages applied at a MOI of 100 to 1,000 rapidly reduced the recoverable bacterial

12. Prevalence of Broad-Host-Range Lytic Bacteriophages of Sphaerotilus natans, Escherichia coli, and Pseudomonas aeruginosa
Two bacteriophage collections were examined with regard to their ability to form plaques on multiple bacterial host species. Nine of 10 phages studied were found to be broad-host-range bacteriophages. These phages fell into two groups. Group 1, the SN series, was isolated from sewage treatment plant samples with Sphaerotilus natans ATCC 13338 as a host. The
