Enterobacter is a genus of common Gram-negative, facultatively anaerobic, rod-shaped, non-spore-forming bacteria of the family Enterobacteriaceae. It is the type genus of the order Enterobacterales. Several strains of these bacteria are pathogenic and cause opportunistic infections in immunocompromised hosts and in those who are on mechanical ventilation. The urinary and respiratory tracts are the most common sites of infection. The genus Enterobacter is a member of the coliform group of bacteria. It does not belong to the fecal coliforms group of bacteria, unlike Escherichia coli, because it is incapable of growth at 44.5 °C in the presence of bile salts. Some of them show quorum sensing properties.
An Nafud or Al-Nefud or The Nefud is a desert in the northern part of the Arabian Peninsula at 28.30°N 41.00°E, occupying a great oval depression. It is 290 kilometres (180 mi) long and 225 kilometres (140 mi) wide, with an area of 103,600 square kilometres (40,000 sq mi).
The Alicyclobacillaceae are a family of Gram-positive bacteria. All members of this family are aerobic and form endospores.
Mycobacterium boenickei is a member of the Mycobacterium fortuitum third biovariant complex. They are rapidly growing ubiquitous environmental organisms that normally inhabit soil, dust and water. These organisms frequently are human pathogens that cause a wide spectrum of clinically significant disease. It is important for practitioners to be aware of these organisms as possible etiological agents, as they are resistant to most first-line anti-tuberculous agents.
Mycobacterium brisbanense is a member of the Mycobacterium fortuitum third biovariant complex. They are rapidly growing ubiquitous environmental organisms that normally inhabit soil, dust and water. These organisms frequently are human pathogens that cause a wide spectrum of clinically significant disease. It is important for practitioners to be aware of these organisms as possible etiological agents, as they are resistant to most first-line anti-tuberculous agents.
Mycobacterium brumae is a rapidly growing environmental mycobacterial species identified in 1993. Aside from one 2004 report of a catheter related bloodstream infection no other infections by this organism have been reported. It was first isolated from water, soil and one human sputum sample in Spain.
Mycobacterium palustre is a slowly growing mycobacterium first isolated from an environmental source in Finland. It is potentially pathogenic, and has been isolated from human and veterinary clinical specimens.
Aggregatibacter actinomycetemcomitans is a Gram-negative, facultative anaerobe, nonmotile bacterium that is often found in association with localized aggressive periodontitis, a severe infection of the periodontium. It is also suspected to be involved in chronic periodontitis. Less frequently, A. actinomycetemcomitans is associated with nonoral infections such as endocarditis. Its role in aggressive periodontitis was first discovered by Danish-born periodontist Jørgen Slots, a professor of dentistry and microbiology at the University of Southern California School of Dentistry.
Psychrobacter phenylpyruvicus is a Gram-negative, catalase- and oxidase-positive, nonmotile bacterium of the genus Psychrobacter, which was isolated from human blood in Belgium. Psychrobacter phenylpyruvicus can cause humans infections such as endocarditis, peritonitis, and fungating lesion of the foot, but those infections caused by this bacterium are rare.
Chryseobacterium treverense is a Gram-negative bacteria from the genus of Chryseobacterium which has been isolated from human blood in Trier in Germany.
Anaerococcus is a genus of bacteria. Its type species is Anaerococcus prevotii. These bacteria are Gram-positive and strictly anaerobic. The genus Anaerococcus was proposed in 2001. Its genome was sequenced in August 2009. The genus Anaerococcus is one of six genera classified within the group GPAC. These six genera are found in the human body as part of the commensal human microbiota.
Parabacteroides is a Gram-negative, anaerobic, non-spore-forming genus from the family "Tannerellaceae".
Parabacteroides gordonii is a Gram-negative, non-spore-forming, rod-shaped and non-motile bacterium from the genus of Parabacteroides which has been isolated from human blood.
Roseomonas is a genus of Gram negative bacteria. The cells are coccoid rods when viewed microscopically. Certain species are known to be opportunistic infections for humans.
Eisenbergiella is a genus of bacteria from the family of Lachnospiraceae.
Eisenbergiella massiliensis is a bacterium from the genus of Eisenbergiella which has been isolated from human feaces.
Luteibacter is a genus of Proteobacteria from the family of Rhodanobacteraceae.
Luteibacter anthropi is a bacterium from the genus of Luteibacter which has been isolated from human blood of a child from Göteborg in Sweden.
Effusibacillus is a genus of Gram-positive, rod-shaped, aerobic, spore-forming bacteria.
Effusibacillus consociatus is a species of Gram positive, aerobic, bacterium. The cells are rod-shaped and form spores. It was first isolated from a blood sample from a 51-year-old woman, although it was not implicated as a pathogen. The species name is derived from Latin consociatus, to indicate that the bacteria was associated with a human clinical case.
