چکیده

Most analyzed Lactococcus lactis strains are predicted to harbor one or more prophage genomes within their chromosome; however, the true extent of the inducibility and functionality of such prophages cannot easily be deduced from sequence analysis alone. Chemical treatment of lysogenic strains with Mitomycin C is known to cause induction of temperate phages, though it is not always easy to clearly identify a lysogenic strain or to measure the number of released phage particles. Here, we report the application of flow cytometry as a reliable tool for the detection and enumeration of released lactococcal prophages using the green dye SYTO-9.

Prophage induction in Lactococcus lactis by the bacteriocin Lactococcin 972.

Lactococcin 972 (Lcn972) is a non-pore forming bacteriocin with a narrow spectrum of activity restricted to Lactococcus. Lcn972 inhibits the incorporation of cell wall precursors in the septum area, thereby inhibiting cell division. In this work, an additional inhibitory effect is described, namely, the induction of the lytic cycle of resident prophages in the lysogenic strain L. lactis IPLA 51...

Induction of Immunogenic Response in BALB/c Mice by Live and Killed Form of Recombinant Lactococcus lactis Displaying EG95 of Echinococcus granulosus Immunogenic Response in BALB/c Mice

Background: CE is a zoonotic parasitic infection caused by Echinococcus granulosus worldwide and is associated with economic losses among livestock animals. EG95 is an immunogenic antigen from the E. granulosus. Lactococcus lactis has been prested as a safe vehicle for antigen delivery. The goal of this study was to design a novel L. lactis strain displaying EG95 as a vaccine delivery system. M...

Flow cytometric assessment of Lactococcus lactis isolates viability after lyophilization

Lactococcus lactis strains tolerance to the lyophilization process is one of the criteria used during the selection of starter cultures in cheese production. The viability of L. lactis strains isolated from silage and milk after the lyophilization process was evaluated in the present study by flow cytometry and cell plate counting. The LIVE/DEAD BacLight TM kit, which contains the dyes SYTO 9 a...

Antigenicity and Immunogenicity of Rotavirus VP6 Protein Expressed on the Surface of Lactococcus lactis

Group A rotaviruses are the major etiologic agents of acute gastroenteritis worldwide in children and young animals. Among its structural proteins, VP6 is the most immunogenic and is highly conserved within this group. Lactococcus lactis is a food-grade, Gram-positive, and nonpathogenic lactic acid bacteria that has already been explored as a mucosal delivery system of heterologous antigens. In...

Genome Sequences of Eight Prophages Isolated from Lactococcus lactis Dairy Strains

P335 group phages represent the most divergent phage group infecting dairy Lactococcus lactis strains and have significant implications for the dairy processing industry. Here, we report the complete genome sequences of eight lactococcal prophages chemically induced from industrial lactococcal strains that propagate lytically on one of two laboratory strains.
