Isolation and Characterization of Lytic Bacteriophages from Wastewater against Listeria monocytogenes
Background and Aims: In the current study, two bacteriophages were isolated from the wastewater sources and characterized by lytic activity against the Listeria monocytogenes (L. monocytogenes) bacterium. Materials and Methods: 50 wastewater samples were collected from the disposal sites. The phages were isolated from the treated samples using the double agar overlay method with L. monocytoge...
متن کاملphenotypic and genotypic characteristics of listeria monocytogenes isolated from dairy and meat products
conclusions mlva analysis showed that samples obtained from different sources could have similar genetic profile. as a result, administration of penicillin in patients with listeriosis (especially pregnant women) and antibiotic susceptibility test are recommended. the fast and accurate methods such as mlva for tracking of pollution sources of l. monocytogenes are recommended during outbreaks. r...
متن کاملPhenotypic and Genotypic Characterization of Atypical Listeria monocytogenes and Listeria innocua Isolated from Swine Slaughterhouses and Meat Markets
In the last decade, atypical Listeria monocytogenes and L. innocua strains have been detected in food and the environment. Because of mutations in the major virulence genes, these strains have different virulence intensities in eukaryotic cells. In this study, we performed phenotypic and genotypic characterization of atypical L. monocytogenes and L. innocua isolates obtained from swine slaughte...
متن کاملEfficacy of a variety of disinfectants against Listeria spp.
The efficacy of 14 disinfectants against Listeria innocua and two strains of Listeria monocytogenes in the presence of organic matter was studied. Quantitative efficacy tests were used. Many of the disinfectants tested were not as effective on Listeria spp. when the test organisms were dried onto the surface of steel disks (carrier tests) as they were when the organisms were placed in suspensio...
متن کاملDomain shuffling and module engineering of Listeria phage endolysins for enhanced lytic activity and binding affinity
Bacteriophage endolysins are peptidoglycan hydrolases employed by the virus to lyse the host at the end of its multiplication phase. They have found many uses in biotechnology; not only as antimicrobials, but also for the development of novel diagnostic tools for rapid detection of pathogenic bacteria. These enzymes generally show a modular organization, consisting of N-terminal enzymatically a...
