A fastidious organism is any organism that has complex or particular nutritional requirements. In other words, a fastidious organism will only grow when specific nutrients are included in its medium. The more restrictive term fastidious microorganism is used in microbiology to describe microorganisms that will grow only if special nutrients are ...
HACEK organisms. The HACEK organisms are a group of fastidious Gram-negative bacteria that are an unusual cause of infective endocarditis, which is an inflammation of the heart due to bacterial infection. [1] HACEK is an abbreviation of the initials of the genera of this group of bacteria: Haemophilus, Aggregatibacter (previously Actinobacillus ...
Granulicatella adiacens is a fastidious Gram-positive cocci (pairs, chains) and is part of the nutritionally variant streptococci (NVS). [2] [3] [4] Like other constituents of the NVS, it can cause bacteremia and infective endocarditis (IE), with significant morbidity and mortality. [4] [2] NVS has less often been implicated in a variety of ...
Xylella fastidiosa is an aerobic, Gram-negative bacterium of the genus Xylella. It is a plant pathogen, that grows in the water transport tissues of plants (xylem vessels) and is transmitted exclusively by xylem sap-feeding insects such as sharpshooters and spittlebugs.
Eikenella corrodens is a pleomorphic bacillus that sometimes appears coccobacillary and typically creates a depression (or "pit") in the agar on which it is growing. Only half produce the pitting of the agar considered characteristic. [citation needed]. It is a slow-growing, facultative anaerobe and a gram-negative bacillus.
Bacillus fastidiosus. Bacillus fastidiosus is an aerobic, motile, rod-shaped bacterium that has been isolated from soil and poultry litter. [1] The species was first isolated and described by the scientist Den Dooren de Jong in 1929. [2] This organism is a mesophile that contains ellipsoidal spores that do not cause swelling of the sporangia.
Capnocytophaga canimorsus. Capnocytophaga canimorsus is a fastidious, slow-growing, Gram-negative rod of the genus Capnocytophaga. [1] [2] It is a commensal bacterium in the normal gingival flora of canine and feline species, but can cause illness in humans. Transmission may occur through bites, licks, or even close proximity with animals. [3]
Moraxella catarrhalis is a fastidious, nonmotile, Gram-negative, aerobic, oxidase-positive diplococcus that can cause infections of the respiratory system, middle ear, eye, central nervous system, and joints of humans. It causes the infection of the host cell by sticking to the host cell using trimeric autotransporter adhesins .
