• A. bovis is catalase-negative, which can differentiate it from other anaerobic diphtheroids. (wikipedia.org)
  • Another difference is that A. Israelii is catalase negative, so it doesn't make an enzyme called catalase, whereas Nocardia is catalase positive. (osmosis.org)

  • Bacteria are microscopic, single-celled organisms. (merckmanuals.com)
  • Calling this bug actinomyces implies that it's morphologically similar to fungus, because both form microscopic branching filaments (or mycelium), while the word Israelii comes from James Adolf Israel, the German surgeon who first described it. (osmosis.org)
  • There are multiple conditions that allow HEPA filters to better capture nanoparticulates and microscopic viruses or bacteria. (terrauniversal.com)
  • The first is called the exogenous theory and was developed by Bostroem in 1891, when he suggested infection is caused by a foreign body, such as hard hay or grass awns. (wikipedia.org)
  • Mycetoma infection can be caused by fungi or bacteria. (medscape.com)
  • These bacteria are normally harmless, but they can cause infections if they enter the body through a cut or wound. (osmosis.org)
  • A. israelii infections are more common in immunocompromised individuals, such as those with HIV / AIDS or cancer. (osmosis.org)
  • Symptoms of A. israelii infections depend on the infected organs and can include fever, lower abdominal pain , chronic cough, and unusual vaginal discharge. (osmosis.org)
  • This bacteria can be identified in a urine culture, and the treatment of its infections involves antibiotics like trimethoprim-sulfamethoxazole , fluoroquinolones, and cephalosporins. (osmosis.org)
  • The disease occurs when there is physical damage to the tissue of the mouth, allowing the bacteria to colonize the deep tissue and bone, typically affecting the mandible and maxilla. (wikipedia.org)
  • Actinomyces israelii is a type of bacteria that typically inhabits the mouth, skin, and gastrointestinal tract . (osmosis.org)
  • In 1913, Pinoy described the mycetoma produced by aerobic bacteria that belong to the actinomycete group and classified mycetomas as those produced by true fungi (eumycetoma) versus those due to aerobic bacteria (actinomycetoma). (medscape.com)
  • It's also facultative anaerobic which means it can survive in both aerobic and anaerobic environments, non-lactose fermenter, oxidase negative which means it doesn't produce this enzyme, and urease positive which means it can produce an enzyme called urease. (osmosis.org)
  • Veronica amygdaline commonly called bitter leaf, is a perennial shrub belonging to the family Asteraceae. (islamicteachings.org)
  • Commonly called Chewing stick, Massularia acuminata (synonym Randia acuminata) is of the family Rubiaceae. (islamicteachings.org)
  • Concerning the microbial content in the yogurt, the lactic acid bacteria (LAB) count was maintained as a control. (bvsalud.org)
  • HEPA filtration systems with far UV-C lamps are well known for rapidly antimicrobial properties against airborne-mediated microbial diseases and hard-to-kill or microbial resistant bacteria. (terrauniversal.com)
  • But wait… that sounds exactly like Nocardia , another group of rod shaped, gram-positive, filamentous bacteria with a lot of other similar features. (osmosis.org)
  • On the other hand, Nocardia has plenty of lipids in its cell wall, so it retains the carbon fuchsin, and it looks red under the microscope, making it an acid-fast bacteria. (osmosis.org)
  • Alright, now, A. Israelii can asymptomatically colonize the oral cavity , particularly the space between the roots and gums , as well as the pharynx , where they gather around the tonsils, and also the intestinal tract, and the urogenital tract, where they coexist with other commensal bacteria. (osmosis.org)
  • If the bacteria have become resistant to this treatment, antibiotic susceptibility testing should be performed to select the best antimicrobial agent or agents to be used. (medscape.com)
  • Compared with healthcare-associated pneumonia (HCAP), it is less likely to involve multidrug-resistant bacteria. (pfmjournal.org)
  • Many bacteria live on and in the bodies of people and animals-on the skin and in the airways, mouth, and digestive, reproductive, and urinary tracts-without causing any harm. (merckmanuals.com)
  • Far UVC light (207-222 nm) efficiently inactivates bacteria without harm to exposed mammalian skin. (terrauniversal.com)
  • The researchers evaluated three common chewing sticks and two brands of toothpaste in southwest Nigeria for the ability to control caries-causing bacteria. (islamicteachings.org)
  • Mycetoma is produced by the introduction of microorganisms (bacteria or fungi) via localized trauma to the skin with thorns, wood splinters, or implantation with solid objects. (medscape.com)
  • Many resident flora are actually helpful to people-for example, by helping them digest food or by preventing the growth of other, more dangerous bacteria. (merckmanuals.com)
  • In 1891, Wolff and Israel ( 6 ) described the cultural characteristics and its anaerobic growth. (cdc.gov)
  • With an increase in tooth decay and gum diseases all over the world, there is need to produce oral cleaning agents that will better control caries-causing bacteria. (islamicteachings.org)
  • With this test, a red dye called carbon fuchsin, binds to lipids in the cell wall, coloring them red. (osmosis.org)
  • In bacteria who don't have a lot of lipids in their cell wall, like A. Israelii, all the red dye is washed off by alcohol , so it looks blue under the microscope, making it a non-acid-fast bacteria. (osmosis.org)
  • First, Proteus mirabilis has flagella, which are lash-like appendages that comes out from the cell body , and confer the bacteria its motility. (osmosis.org)
  • Several researchers were then able to conclude that the bacteria are part of the normal flora of the mouth, making the mouth a source of disease. (wikipedia.org)
