Aerococcus
''Aerococcus'' is a genus in the phylum Bacillota (Bacteria). The genus was first identified in 1953 from samples of air and dust as a catalase-negative, gram-positive coccus that grew in small clusters. They were subsequently found in hospital environments and meat-curing brines. It has been difficult to identify as it resembles alpha-hemolytic ''Streptococcus'' on blood agar plates and is difficult to identify by biochemical means. Sequencing of 16S rRNA has become the gold standard for identification, but other techniques such as MALDI-TOF have also been useful for identifying both the genus and species. Etymology The name ''Aerococcus'' derives from the Greek ''aer, aeros'' (ἀήρ, ἀέρος), air; New Latin ''coccus'' (from Greek''kokkos'' (κόκκος)), a berry; New Latin ''Aerococcus'', air coccus. The name was given based on its round shape and that it was first discovered in air samples. Species The genus contains these species: * '' A. christensenii'' Collin ...

Aerococcus Urinae
''Aerococcus urinae'' is a Gram-positive bacterium associated with urinary tract infections. Classification ''Aerococcus urinae'' is a member of the bacterial genus ''Aerococcus''. The bacterium is a Gram-positive, catalase-negative coccus growing in clusters. Isolates of this genus were originally isolated in 1953 from samples collected in the air and dust of occupied rooms and were distinguished by their tetrad cellular arrangements. Later, it was found in the urine of patients with urinary tract infections and in 1992, ''A. urinae'' was assigned as distinct species. Due to difficulties in the biochemical identification of ''A. urinae'' in clinical microbiological laboratories, the incidence of infections with this bacterium has likely been underestimated and secure identification relies on genetic techniques like 16S ribosomal subunit sequencing or mass spectroscopic methods such as MALDI-TOF. Clinical relevance ''A. urinae'' may also cause invasive infections including ur ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Aerococcus Sanguinicola
''Aerococcus sanguinicola'' is a member of the bacterial genus ''Aerococcus'' and is a Gram-positive, catalase-negative coccus growing in clusters. This species was defined in 2001 and has since then been increasingly recognized as a pathogen causing urinary tract infections and also invasive infections including infective endocarditis. Commercially available biochemical tests fail to properly identify ''A. sanguinicola'' and correct identification can be achieved through genetic or mass spectroscopic methods, such as matrix-assisted laser desorption/ionization time of flight (MALDI-TOF In mass spectrometry, matrix-assisted laser desorption/ionization (MALDI) is an ionization technique that uses a laser energy absorbing matrix to create ions from large molecules with minimal fragmentation. It has been applied to the analysis of ...). ''A. sanguinicola'' is, with ''A. urinae'', the most common aerococcus isolated from urine, but from blood, ''A. urinae'' is much more commonl ...

Gaffkaemia
Gaffkaemia (gaffkemia in American English) is a bacterial disease of lobsters, caused by the Gram-positive lactic acid bacterium ''Aerococcus viridans'' var. ''homari''. Discovery Gaffkaemia was first discovered in 1947 in American lobsters (''Homarus americanus'') in a holding tank in Maine. It was originally described as "''Gaffkya homari''" by Hitcher and Snieszko, but the genus name ''Gaffkya'' was rejected in 1971, and the gaffkaemia bacterium was recognised as a subspecies or variety of '' Aerococcus viridans'' by Kelly and Evans in 1974. Effects The effects of gaffkaemia infection include lethargy (typically seen as a drooping tail), anorexia and a pink colour on the ventral side of the abdomen, which gives the disease its alternative common name of red tail disease. When lobsters are moribund, they may lie on their sides, and frequently lose appendages. The effects of gaffkaemia are slowed by low temperatures, such that death can occur within two days of infection at , bu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Lactobacillales
Lactobacillales are an order of gram-positive, low-GC, acid-tolerant, generally nonsporulating, nonrespiring, either rod-shaped (bacilli) or spherical (cocci) bacteria that share common metabolic and physiological characteristics. These bacteria, usually found in decomposing plants and milk products, produce lactic acid as the major metabolic end product of carbohydrate fermentation, giving them the common name lactic acid bacteria (LAB). Production of lactic acid has linked LAB with food fermentations, as acidification inhibits the growth of spoilage agents. Proteinaceous bacteriocins are produced by several LAB strains and provide an additional hurdle for spoilage and pathogenic microorganisms. Furthermore, lactic acid and other metabolic products contribute to the organoleptic and textural profile of a food item. The industrial importance of the LAB is further evidenced by their generally recognized as safe (GRAS) status, due to their ubiquitous appearance in food and th ...

Microbiology
Microbiology () is the scientific study of microorganisms, those being unicellular (single cell), multicellular (cell colony), or acellular (lacking cells). Microbiology encompasses numerous sub-disciplines including virology, bacteriology, protistology, mycology, immunology, and parasitology. Eukaryotic microorganisms possess membrane-bound organelles and include fungi and protists, whereas prokaryotic organisms—all of which are microorganisms—are conventionally classified as lacking membrane-bound organelles and include Bacteria and Archaea. Microbiologists traditionally relied on culture, staining, and microscopy. However, less than 1% of the microorganisms present in common environments can be cultured in isolation using current means. Microbiologists often rely on molecular biology tools such as DNA sequence based identification, for example the 16S rRNA gene sequence used for bacteria identification. Viruses have been variably classified as organisms, as the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
