Abstract

A study of phenotypic and genotypic characteristics was carried out on 182 strains isolated from soil of different geographical areas; the type strains were B. licheniformis, B. subtilis, B. pumilus, B. cereus and B. coagulans. The results showed, primarily on the basis of phenotypic features, that all the isolates belonged to the B. licheniformis species, however DNA relatedness studies revealed only 161 to be genetically related to B. licheniformis, the DNA relatedness levels ranging from 66 to 100%. The other 21 isolates appeared to be genetically distinct not only from B. licheniformis but also from B. subtilis and B. pumilus, where there were low levels of DNA relatedness (from 4 to 37%). Nevertheless the ARDRA results indicate that the 21 atypical isolates were phylogenetically related to B. licheniformis. Our data and the phenotypic homogeneity found suggest the presence of three different genomovars.

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.

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.

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.

Hereditary Sensory Autonomic Neuropathies are a group of inherited neurodegenerative disorders characterized clinically by loss of sensation and autonomic dysfunction. Here is the latest research on these neuropathies.

Glut1 Deficiency

Glut1 deficiency, an autosomal dominant, genetic metabolic disorder associated with a deficiency of GLUT1, the protein that transports glucose across the blood brain barrier, is characterized by mental and motor developmental delays and infantile seizures.
