Enterobacter aerogenes Enterobacter aerogenes is a Gram-negative, oxidase negative, catalase positive, citrate positive, indole negative, rod-shaped bacterium. E. aerogenes is a nosocomial and pathogenic bacterium that causes opportunistic infections including most types of infections.ome of the infections caused by E. aerogenes result from specific antibiotic treatments, venous catheter insertions, and/or surgical procedures. E. aerogenes is generally found in the human gastrointestinal tract and does not generally cause disease in healthy individuals.

- Yes: Enterobacter aerogenes is a bacteria that can cause a variety of infections such as urinary tract infections, sepsis, pneumonia, skin/wound infections. It typically does not occur in people who are otherwise healthy.

- Introduction. The Enterobacteriaceae are a large family of gram-negative bacilli that are normal inhabitants of the gastrointestinal tract of humans and other animals (1). These organisms are a common cause of community-acquired and health-care–acquired infections.he past several decades have seen the spread of Enterobacteriaceae with resistance to broad-spectrum antimicrobials; however, clinicians in the United States have relied on the carbapenem antimicrobial class (imipenem, meropenem, doripenem, and ertapenem) to treat infections caused by these resistant organisms.

Enterobacter cloacae Enterobacter cloacae is a clinically significant Gram-negative, facultatively-anaerobic, rod-shaped bacterium.nterobacter cloacae is a member of the normal gut flora of many humans and is not usually a primary pathogen. It is sometimes associated with urinary tract and respiratory tract infections.

Enterococcus faecalis Enterococcus faecalis – formerly classified as part of the group D Streptococcus system – is a Gram-positive, commensal bacterium inhabiting the gastrointestinal tracts of humans and other mammals.hysiology [edit]. E. faecalis is a nonmotile, Aerotolerant anaerobic microbe; it ferments glucose without gas production, and does not produce a catalase reaction with hydrogen peroxide.

Klebsiella pneumoniae Klebsiella pneumoniae is a Gram-negative, nonmotile, encapsulated, lactose-fermenting, facultative anaerobic, rod-shaped bacterium.s a free-living diazotroph, its nitrogen fixation system has been much-studied, and is of agricultural interest, as K. pneumoniae has been demonstrated to increase crop yields in agricultural conditions. Members of the Klebsiella genus typically express two types of antigens on their cell surfaces.

Enterobacter species Pneumonitis. Enterobacter species are the third most common cause of nosocomial gram-negative bacillary respiratory infections; as with other aerobic gram-negative rods, risk factors include severity of illness, mechanical ventilation, and prior antibiotic exposure (8).ram negative bacilli resistant to third-generation cephalosporins, particularly P. aeruginosa, Enterobacter species, and Stenotrophomonas maltophilia were the major organisms accounting for inadequate therapy (32).

- Making the world better, one answer at a time. No, Staphylococcus Aureus is a gram positive facultative anaerobe. It has a cell wall surrounding a peptidoglycan layer, however does not produce an endospore like many other gram positive bacteria. Staphylococcus Aureus is a cocci shaped bacteria with pyogenic properties.

- Gram-positive bacteria retain a purple-colored stain, while Gram-negative bacteria appear pinkish or red. Gram-negative bacteria can cause many types of infections and are spread to humans in a variety of ways. Several species, including Escherichia coli, are common causes of food–borne disease.Vibrio cholerae —the bacteria responsible for cholera—is a waterborne pathogen. Gram-negative bacteria can also cause respiratory infections, such as certain types of pneumonia, and sexually transmitted diseases, including gonorrhea.Yersinia pestis, the Gram-negative bacterium responsible for plague, is transmitted to people through the bite of an infected insect or handling an infected animal.ram-positive bacteria retain a purple-colored stain, while Gram-negative bacteria appear pinkish or red.

ETS Official Guide to the GRE Revised General Test 3rd Edition Book Review One complaint I have is that the practice questions for reviewing fundamentals in this book, don’t prepare you that well for the real GRE. Which is fine if you are new to the test. To reiterate: the 3rd Edition ETS Official Guide, like the 2nd Edition guide, is not an all-in-one guide.

Antimicrobial therapy of infections with aerobic Gram-positive rods Infections with Gram-positive rods are rare in comparison with those caused by Gram-positive cocci or Gram-negative rods. Gram-positive rods do not often figure in antibiotic susceptibility studies, and very few, if any, large-scale or controlled clinical studies with these organisms are available.

Enterobacter aerogenes In other words, E. aerogenes resembles E. cloacae but the leusine decarboxylase test is positive and gelatin liquification is late. E. aerogenes is also, often times confused with Klebsiella aerogenes. However, E. aerogenes is motile and urease negative while K. aerogenes is nonmotile and urease positive (5).

- Species of Aeromonas are Gram-negative, non-spore-forming, rod-shaped, facul-. tatively anaerobic bacteria that occur ubiquitously and autochthonously in. aquatic environments. Although historically the Aeromonas genus has been placed. in the family Vibrionaceae (Popoff, 1984), there have been proposals to place it. in its own family, the Aeromonadaceae (Colwell, MacDonnell & De Ley, 1986).
