Probiotics and Antimicrobial Proteins
Andrea LaukováL'ubomír Ondruška

Abstract

Enterococci are ubiquitous microbiota constituting a large proportion of autochthonous microflora in animals. Some produce bacteriocins mostly enterocins; some of bacteriocin-producing strains also possess probiotic properties. Enterococcus faecium AL 41, Ent M-producing strain was tested for beneficial effect in rabbits. Five-week-old animals (72, Hycole) were divided into experimental groups (E1, E2) and control (C); 24 animals in each. Rabbits in E1 were administered AL 41 (500 μl per animal/day, 10(9) cfu/ml) in water for 21 days; rabbits in E2 were administered Ent M (50 μl/animal/day, activity 12,800 AU/ml) in water for 21 days. Rabbits in C fed a commercial diet. The experiment lasted 42 days. Sampling of faeces and blood was provided on day 0-1 and 21, 42; 3 animals per group were slaughtered. Caecum and appendix were separated. AL 41 colonized rabbits intestines <1.0 (log10) cfu/g, but stimulation of immunity was noted (P < 0.01; P < 0.001). Antimicrobial activity of both was noticed in faeces and/or caecum against pseudomonads. Significant decrease of coliform bacteria in faeces of E1 was noted on day 42 comparing with E2 (P < 0.05). On day 21, S. aureus cells were not detected in E1, E2. On day 42, S. aureus was not ...Continue Reading

COVID-19

Coronaviruses encompass a large family of viruses that cause the common cold as well as more serious diseases, such as the ongoing outbreak of coronavirus disease 2019 (COVID-19; formally known as 2019-nCoV). Coronaviruses can spread from animals to humans; symptoms include fever, cough, shortness of breath, and breathing difficulties; in more severe cases, infection can lead to death. This feed covers recent research on COVID-19.

Blastomycosis

Blastomycosis fungal infections spread through inhaling Blastomyces dermatitidis spores. Discover the latest research on blastomycosis fungal infections here.

Nuclear Pore Complex in ALS/FTD

Alterations in nucleocytoplasmic transport, controlled by the nuclear pore complex, may be involved in the pathomechanism underlying multiple neurodegenerative diseases including Amyotrophic Lateral Sclerosis and Frontotemporal Dementia. Here is the latest research on the nuclear pore complex in ALS and FTD.

Applications of Molecular Barcoding

The concept of molecular barcoding is that each original DNA or RNA molecule is attached to a unique sequence barcode. Sequence reads having different barcodes represent different original molecules, while sequence reads having the same barcode are results of PCR duplication from one original molecule. Discover the latest research on molecular barcoding here.

Chronic Fatigue Syndrome

Chronic fatigue syndrome is a disease characterized by unexplained disabling fatigue; the pathology of which is incompletely understood. Discover the latest research on chronic fatigue syndrome here.

Evolution of Pluripotency

Pluripotency refers to the ability of a cell to develop into three primary germ cell layers of the embryo. This feed focuses on the mechanisms that underlie the evolution of pluripotency. Here is the latest research.

Position Effect Variegation

Position Effect Variagation occurs when a gene is inactivated due to its positioning near heterochromatic regions within a chromosome. Discover the latest research on Position Effect Variagation here.

STING Receptor Agonists

Stimulator of IFN genes (STING) are a group of transmembrane proteins that are involved in the induction of type I interferon that is important in the innate immune response. The stimulation of STING has been an active area of research in the treatment of cancer and infectious diseases. Here is the latest research on STING receptor agonists.

Microbicide

Microbicides are products that can be applied to vaginal or rectal mucosal surfaces with the goal of preventing, or at least significantly reducing, the transmission of sexually transmitted infections. Here is the latest research on microbicides.
