Fungi-like protists are a group of eukaryotic microbes that resemble true fungi in form and function but are not closely related to them. They share key features with fungi, suc...

Autotrophic prokaryotes are microscopic organisms, typically single-celled, that use carbon dioxide as their main carbon source and build their own organic compounds using exter...

Bacteroides fragilis is a Gram‑negative, anaerobic bacterium commonly found in the human gut microbiome. As part of the Bacteroidetes phylum, it helps with carbohydrate metabo...

Mesophiles are organisms that grow best at moderate temperatures, typically between 20°C and 45°C (68°F to 113°F). This group includes many familiar bacteria, archaea, fungi...

Gram-positive cocci in pairs and chains describe a common microscopic pattern seen in clinical and environmental specimens. This morphology immediately narrows the range of like...

Bacteria are single-celled prokaryotic organisms found in almost every environment, while bacteriophages (phages) are viruses that specifically infect bacteria by injecting thei...

Nonenveloped (naked) RNA viruses, such as picornaviruses (including poliovirus and rhinovirus), are most likely to be released by lysis of the host cell. These viruses typically...

Archaebacteria, now more commonly called archaea, are a domain of single‑celled microorganisms distinct from bacteria and eukaryotes. They are notable for thriving in extreme...

Archaea, once labeled archaebacteria, are single-celled prokaryotes distinct from bacteria and eukaryotes. Their nutritional modes vary by lineage and environment. The short ans...

Archaebacteria, now widely referred to as Archaea, represent a domain of single-celled microorganisms distinct from bacteria and eukaryotes. Their cell type is characterized by...
