How do you get Alcaligenes faecalis?

Introduction. Alcaligenes faecalis (A. faecalis) is a Gram-negative, obligate aerobic, oxidase-positive, catalase-positive, and nonfermenting bacterium. It is commonly found in soil, water, and in hospital settings, such as in respirators, hemodialysis systems, and intravenous solutions [1, 2].

Where is alcaligenes found?

Natural habitat. Alcaligenes are found in soil and water and are common inhabitants of the intestinal tracts of some animals.

How common is Alcaligenes faecalis?

faecalis were less than 50%. Conclusions: The most frequent Alcaligenes faecalis infection sites, in order, are the bloodstream, urinary tract, skin and soft tissue, and middle ear. The susceptibility rate of Alcaligenes faecalis to commonly used antibiotics is decreasing.

Where is Pseudomonas alcaligenes found?

Pseudomonas alcaligenes is a Gram-negative aerobic rod belonging to the bacterial family Pseudomonadaceae and is a common inhabitant of soil and water.

How is Alcaligenes faecalis treated?

Extensively drug-resistant infections have been reported since 2018. The best sensitivity rate to Alcaligenes faecalis was 66.7% for three antibiotics (imipenem, meropenem, and ceftazidime) in 2019. Two antibiotics (ciprofloxacin and piperacillin/tazobactam) sensitivity rates to A.

Where is Alcaligenes faecalis found?

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.

What is Alcaligenes faecalis?

Alcaligenes faecalis. Image from Visuals Unlimited. Species of Alcaligenes generate energy in a number of ways, including arsenite oxidation. Much about these organisms is virtually unknown, and even identifying its species correctly presents challenges.

How many species are there in the genus Alcaligenes?

Bergey’s Manual of Determinative Bacteriology (9th ed.) lists seven species in the genus: Alcaligenes eutrophus, Alcaligenes latus, Alcaligenes faecalis, Alcaligenes paradoxus, Alcaligenes piechaudii, Alcaligenes xylosoxidans subsp. xylosoxidans, and A. xylosoxidans subsp. denitrificans.

What are the side effects of Alcaligenes?

Alcaligenes. 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.

Where do you find Alcaligenes in the body?

Alcaligenes. Strains of Alcaligene s (such as A. faecalis) are found mostly in the intestinal tracts of vertebrates, decaying materials, dairy products, water, and soil; they can be isolated from human respiratory and gastrointestinal tracts and wounds in hospitalized patients with compromised immune systems.
