Bacterial species may exist, metagenomics reveal.

Whether or not bacterial species exist remains an unresolved issue of paramount theoretical as well as practical consequences. Here we review and synthesize the findings emerging from metagenomic surveys of natural microbial populations and argue that microbial communities are predominantly organized in genetically and ecologically discernible populations, which possess the attributes expected ...

Confusing medical terms: disease that may or may not exist.

Patients often quote diseases or illnesses that either do not exist per se or are hard to prove that they exist. Often symptoms are vague and, therefore, difficult for patients to qualify in a language clinicians can understand, interpret and act upon. Physicians often perpetuate this by giving 'diagnoses of exclusion', or using poor explanations, oversimplifications, conflicting diagnostic cri...

Figure 25-4 Bacterial shapes and cell-surface structures Bacteria are classified into three different shapes: (A) spheres (cocci), (B) rods (bacilli), and (C) spiral cells (spirochetes). (D) They are also classified as Gram-positive or Gram-negative. Bacteria such as Streptococci and Staphylococci have a single membrane and a thick cell wall made of cross-linked peptidoglycan. They retain the v...

Bracken: estimating species abundance in metagenomics data

Metagenomic experiments attempt to characterize microbial communities using high-throughput DNA sequencing. Identification of the microorganisms in a sample provides information about the genetic profile, population structure, and role of microorganisms within an environment. Until recently, most metagenomics studies focused on high-level characterization at the level of phyla, or alternatively...

Population Genomics: How Bacterial Species Form and Why They Don't Exist

Two processes suggested to drive bacterial speciation - periodic selection and recombination - are generally thought to be mutually opposed. Recent work shows that data taken as evidence supporting the former may be explained by the latter, raising further problems for the idea of bacterial 'species'.
