Lysogeny in Lactobacilli [PDF]

Journal of General Microbiology, 1974
Summary: Strains of lactobacilli were examined for lysogeny after treatment with mitomycin C. Forty strains belonging to 7 species out of 148 strains of 15 species were lysed by mitomycin C. Lysis was strongly dependent upon the concentration of mitomycin C, temperature and the age of the cultures.

Lactobacilli on Plants [PDF]

Applied Microbiology, 1968
The distribution, enumeration, and identification of lactobacilli on vegetable plants were studied in an area described geographically as being subtropical and moist. The lactobacilli were obtained, by means of quantitative enrichment procedures in Rogosa's SL broth, from 35.3% of all samples incubated at 32 C, and from 15.4% of the ...

Probiotic Lactobacilli Do Not Protect Chickens against Salmonella Enteritidis Infection by Competitive Exclusion in the Intestinal Tract but in Feed, Outside the Chicken Host

Microorganisms, 2022
Lactobacilli are commonly used as probiotics in poultry to improve production parameters and to increase chicken resistance to enteric infections. However, lactobacilli do not efficiently colonise the chicken intestinal tract, and also, their anti ...

Modulation of respiratory TLR3-antiviral response by probiotic microorganisms: lessons learned from Lactobacillus rhamnosus CRL1505

Frontiers in Immunology, 2014
Respiratory syncytial virus (RSV) is the leading cause of lower respiratory tract illness in infants and young children. Host immune response is implicated in both protective and immunopathological mechanisms during RSV infection. Activation of Toll-like

Modulation of intestinal TLR4-inflammatory signalling pathways by probiotic microorganisms: lessons learned from Lactobacillus jensenii TL2937

Frontiers in Immunology, 2014
The intestinal mucosa plays a critical role in the host's interactions with innocuous commensal microbiota and invading pathogenic microorganisms. Intestinal epithelial cells (IECs) and gut associated immune cells recognize the bacterial components via ...

Exogenous lactobacilli mitigate microbial changes associated with grain fermentation (corn, oats, and wheat) by equine fecal microflora ex vivo. [PDF]

PLoS ONE, 2017
Cereal grains are often included in equine diets. When starch intake exceeds foregut digestion starch will reach the hindgut, impacting microbial ecology. Probiotics (e.g., lactobacilli) are reported to mitigate GI dysbioses in other species.

PCR-based screening, isolation, and partial characterization of motile lactobacilli from various animal feces

BMC Microbiology, 2020
Background Most lactobacilli found in animal intestines are generally non-motile, but there are few exceptions. Our previous work showed that Lactobacillus agilis BKN88, which is a highly motile strain originating from a chicken, takes advantage of ...

Effects of probiotic lactobacilli on inflammatory responses to Escherichia coli in pig intestinal cells

Academia Biology
In the swine industry, the increased awareness of the in-feed use of antibiotics due to the emergence of resistant bacteria led to an intense search for alternative strategies.

Lactobacillus fermentum and Lactobacillus crispatus Do Not Have Cytotoxic Effects on HN5 Oral Squamous Cell Carcinoma Cell Line

International Journal of Dentistry, 2021
Background. The oral environment has a very complex normal flora and a wide variety of bacteria including lactobacilli. Studies have shown oral microbial flora has important influence in the development of oral cancer.
