It has been reported to cause sepsis, meningitis, peritonitis, enteric fever, appendicitis, cystitis, chronic suppurative otitis media, abscesses, arthritis, pneumonitis, and endocarditis. It has been associated with fatal outcomes because these organisms are resistant to commonly used antibiotics.How is Alcaligenes faecalis transmitted?
Alcaligenes faecalis is a gram-negative bacterium that is commonly found in the environment. This pathogen is usually transmitted in the form of droplets through ventilation equipment and nebulizers, but transmission through direct contact has also been documented in few case reports.
How do you treat Alcaligenes faecalis?
Alcaligenes faecalis is generally resistant to aminoglycosides, chloramphenicol and tetracyclines and usually susceptible to trimethoprim–sulfamethoxazole and β-lactam antibiotics such as ureidopenicillins, ticarcillin–clavulanic acid, cephalosporins and carbapenems.

Article first time published onIs Alcaligenes faecalis alkaline tolerant?
Alcaligenes faecalis is a gram-negative rod with flagella belonging to the family of Alcaligenaceae. It is a nonfermentative aerobic, nonencapsulated, oxidase-positive bacterium and named for its ability to produce an alkaline reaction in certain medium [1].
What is the habitat of Alcaligenes faecalis?
Alcaligenes faecalis was first discovered in feces, and is commonly found in soil, water, and other environments (14,–16). Currently, this bacterium has wide applications in the sewage treatment and pharmaceutical industries.
Where is alcaligenes found?
Alcaligenes are found in soil and water and are common inhabitants of the intestinal tracts of some animals.
Is Alcaligenes faecalis normal flora?
Alcaligenes faecalis is a gram-negative organism that is commonly found in the environment and may also be a part of normal fecal flora in humans.
What does Alcaligenes faecalis smell like?
The distinctive properties of an Alcaligenes-like organism isolated from human pathological material are described. The organism is readily recognizable by its characteristic colonial appearances, fruity smell and greening of blood agar.
Is Alcaligenes faecalis citrate positive or negative?
Alcaligenes faecalis is a Gram-negative catalase- and oxidase-positive, motile rod. It is commonly found in a watery environment and is rarely isolated from humans.
How does Proteus cause UTI?
Proteus species also produce urease, which has been shown to be associated with an increased risk of pyelonephritis and upper UTIs. Proteus species also hydrolyze urea to ammonia, thereby alkalinizing the urine. Through the production of urease and ammonia, Proteus can produce an environment where it can survive.
What happens when you have cystitis?
Cystitis signs and symptoms often include: A strong, persistent urge to urinate. A burning sensation when urinating. Passing frequent, small amounts of urine.
How do you get a Proteus UTI?
How is Proteus mirabilis transmitted? The bacterium spreads mainly through contact with infected persons or contaminated objects and surfaces. The pathogens can also be ingested via the intestinal tract, for example, when it is present in contaminated food. The germs spread quickly because they are very agile.
What pH does Alcaligenes faecalis grow?
It is also pH-dependent in vitro with an optimum between 5.8 and 7.
What color is Alcaligenes faecalis?

Does Alcaligenes faecalis produce acid?
R-(-)-Mandelic acid was produced from racemic mandelonitrile by Alcaligenes faecalis ATCC 8750. Ammonium acetate or L-glutamic acid as the carbon source and n-butyronitrile as the inducer in the culture medium were effective for bacterial growth and the induction of R-(-)-mandelic acid-producing activity.
Are Alcaligenes pathogenic?
Achromobacter and Alcaligenes spp. are opportunistic human pathogens causing sporadic cases of pneumonia, septicemia, peritonitis, and urinary tract and other infections.
Does Alcaligenes faecalis grow on MacConkey Agar?
