Abstract

Potassium tellurite media gave the highest detrimental effects on the generation number of all tested faecal streptococci species. This applies to all investigated vehicles. However, drastic tellurite effects became more conspicuous with certain vehicles than with others. This is particularly true with acid and alkaline foods and water, especially with strains like Streptococcus bovis, Str. faecium, and Str. durans. Again, tellurite becomes more influencial with regard to old cells rather than young cells in the logarithmic phase. On the other hand, the use of thallous acetate as a concentration agent secured better results than either the tellurite or azide almost with all tested vehicles. Yet, sodium azide may be regarded as holding an intermediate position between tellurite and thallous acetate in terms of vehicles, Streptococcus species, and age of pollution. A lower number of generation resulted with all tested faecal streptococci species, using liquid media bearing more than one concentrating agent. This applied to water and milk examination.

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.

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.

Central Pontine Myelinolysis

Central Pontine Myelinolysis is a neurologic disorder caused most frequently by rapid correction of hyponatremia and is characterized by demyelination that affects the central portion of the base of the pons. Here is the latest research on this disease.

Myocardial stunning is a mechanical dysfunction that persists after reperfusion of previously ischemic tissue in the absence of irreversible damage including myocardial necrosis. Here is the latest research.

Pontocerebellar Hypoplasia

Pontocerebellar hypoplasias are a group of neurodegenerative autosomal recessive disorders with prenatal onset, atrophy or hypoplasia of the cerebellum, hypoplasia of the ventral pons, microcephaly, variable neocortical atrophy and severe mental and motor impairments. Here is the latest research on pontocerebellar hypoplasia.

Cell Atlas Along the Gut-Brain Axis

Profiling cells along the gut-brain axis at the single cell level will provide unique information for each cell type, a three-dimensional map of how cell types work together to form tissues, and insights into how changes in the map underlie health and disease of the GI system and its crosstalk with the brain. Disocver the latest research on single cell analysis of the gut-brain axis here.
