The biggest known viruses are Mimivirus (750 nanometer capsid, 1.2 million base pair DNA) and Megavirus (680 nanometer capsid, 1.3 million base pair DNA). These giant viruses have all been isolated from environmental samples, and many infect amoebae. A new Mimivirus has now been isolated from a human patient with pneumonia. To search for giant …
The mucosal membranes that line our respiratory, alimentary, and urogenital tracts and the outer surface of the eyes are portals of entry for microbes. The cells at these surfaces have functions that require that they are exposed to the environment – for example, gaseous exchange in the lung between inspired air and the blood. Mucus, …
Microbial communities are found at many different sites on the human body, including nasal passages, oral cavities, skin, gastrointestinal tract, and urogenital tract. These commensal microbes shape the immune and metabolic status of the host and play important roles in human health and disease. The brain is one organ that has been assumed to be …
