Bacillus subtilis, known also as the hay bacillus or grass bacillus, is a Gram-positive, catalase-positive bacterium, found in soil and the gastrointestinal tract of ruminants and humans. A member of the genus Bacillus, B. subtilis is rod-shaped, and can form a tough, protective endospore, allowing it to tolerate extreme environmental conditions. B. subtilis has historically been classified as an obligate aerobe, though evidence exists that it is a facultative aerobe. B. subtilis is considered the best studied Gram-positive
RM2BE0JCD–Transmission Electron Micrograph (TEM) of Escherichia coli (E. coli) O157:H7 showing flagella (pseudoreplica technique). The bacterium is a known cause of foodborne illness. The strain of E. coli, O157:H7, was first recognized in 1982 during an outbreak of severe diarrhea that was caused by contaminated hamburgers. Infection can be prevented by making sure that meat is cooked thoroughly. Escherichia coli is a gram-negative, facultatively anaerobic, rod-shaped, coliform bacterium of the genus Escherichia that is commonly found in the lower intestine of warm-blooded organisms (endotherms).

RM2BE0J9X–Negative-stained Transmission Electron Micrograph (TEM) showing you a number of Influenza A virions. Influenza A virus causes influenza in birds and some mammals, and is the only species of influenza virus A. Influenza virus A is a genus of the Orthomyxoviridae family of viruses. Strains of all subtypes of influenza A virus have been isolated from wild birds, although disease is uncommon. Some isolates of influenza A virus cause severe disease both in domestic poultry and, rarely, in humans. Occasionally, viruses are transmitted from wild aquatic birds to domestic poultry, and this may cause a
RM2BE0GJ4–Scanning electron micrograph SEM) of a number of Gram-positive bacilli, or 'rod-shaped', Mycobacterium fortuitum bacteria. M. fortuitum is classified as a 'rapidly-growing' Mycobacterium, due to the fact that it can be grown on laboratory culture medium in less than 7 days. As a human pathogen, this organism has been determined to be the cause of skin infections, including furunculosis, i.e., boils, on the legs of people receiving pedicures in nail salons. As a nontuberculous bacterium (NTB), M. fortuitum is a member of the same genus as its cousin Mycobacterium tuberculosis, however, it is cl

RM2BE0JC2–Negative-stained Transmission Electron Micrograph (TEM) demonstrating the brick-shaped monkeypox virus from a cell culture. The surface mulberry virion is covered with short, whorled filaments. Monkeypox virus (MPV) is a double-stranded DNA, zoonotic virus and a species of the genus Orthopoxvirus in the family Poxviridae. It is one of the human orthopoxviruses that includes variola (VARV), cowpox (CPX), and vaccinia (VACV) viruses. But it is not a direct ancestor to, nor a direct descendent of, the variola virus which causes smallpox. The monkeypox virus causes a disease that is similar to sma

The surface capsular virion penetrated by stain present as a sharply defined, dense core surrounded by several laminated zones of differing densities. Monkeypox virus (MPV) is a double-stranded DNA, zoonotic virus and a species of the genus Orthopoxvirus in the family Poxviridae.

RM2BE0JAE–Transmission Electron Micrograph (TEM) of the Marburg virus. Marburg virus (MARV) is a hemorrhagic fever virus of the Filoviridae family of viruses and a member of the species Marburg marburgvirus, genus Marburgvirus. MARV causes Marburg virus disease in humans and nonhuman primates, a form of viral hemorrhagic fever. The virus is considered to be extremely dangerous. The WHO rates it as a Risk Group 4 Pathogen (requiring biosafety level 4-equivalent containment). In the United States, the NIH/NIAID ranks it as a Category A Priority Pathogen and the CDC lists it as a Category A Bioterrorism Ag
RM2BE0JC6–Scanning Electron Micrograph (SEM) of the Ebola virus. The virus was named after a river in the Democratid Republic of the Congo where it was first discovered in 1976. It is an RNA virus (of the family Filoviridae) known to cause the often fatal disease Ebola hemorragic fever (Ebola HF) in primates. Ebola virus (EBOV, formerly designated Zaire ebolavirus) is one of five known viruses within the genus Ebolavirus. Four of the five known ebolaviruses, including EBOV, cause a severe and often fatal hemorrhagic fever in humans and other mammals, known as Ebola virus disease (EVD). Ebola virus has c

The cave bear (Ursus spelaeus) was a species of bear that lived in Europe during the Pleistocene and became extinct at the beginning of the Last Glacial Maximum, about 27,500 years ago. Mammoths can be seen in the background. A mammoth is any species of the extinct genus Mammuthus, proboscideans commonly equipped with long, curved tusks and, in northern species, a covering of long hair.
