this genus is still included with the low G+C gram-positive bacteria. The genusMycoplasmaincludes more than 100 species, which share several unique characteristics. They are very small cells, some with a diameter of about 0.2 μm, which is smaller than some large viruses...
The most common infecting organisms were Escherichia coli among gram-negative bacteria and Enterococcus species (Enterococcus casseliflavus and Enterococcus faecalis) among gram-positive bacteria. There were no differences in mortality, re-admission rate, and need for emergency decompression procedures between...
Within Gram-positive bacteria, the expression of target genes is controlled at the population level via signaling peptides, also known as pheromones. Pheromones control a wide range of functions, including competence, virulence, and others that remain unknown. Until now, their role in bacterial gene...
Microbiology - Bacteria, Viruses, Fungi: The major groups of microorganisms—namely bacteria, archaea, fungi (yeasts and molds), algae, protozoa, and viruses—are summarized below. Links to the more detailed articles on each of the major groups are provi
Tests used to identify Gram Positive Bacteria Mannitol Salt Agar (MSA) This type of medium is both selective and differential. The MSA will select for organisms such as Staphylococcus species which can live in areas of high salt concentration (plate on the left in the picture below). This is...
This study demonstrates that increasing isolation within an indoor space is associated with decreased microbial diversity and a shift from Gram-positive bacteria such as Actinobacteria and Firmicutes, to Gram-negative Proteobacteria, many of which are antibiotic-resistant.
