Klebsiella pneumoniae. and E. coli are: this facilitates performing the test in the microbiology laboratory without the use of molecular methods, and these organisms represent the majority of CREs encountered in the United States. Saved by Kim Thomas. It appears as a mucoid lactose fermenter on MacConkey agar. The Klebsiella-type strain, K. pneumoniae, is a model system in N 2 fixation, but other strains of this same species are feared pathogens. Of the pathogenic Klebsiella species, K. pneumoniae is the most prevalent and clinically important. Also, the use of antibiotics can be a factor that increases the risk of nosocomial infection with Klebsiella bacteria. In recent years, Klebsiella species have become important pathogens in nosocomial infections. In early September of the same year, she developed septic shock and died.

The concern is that carbapenem is often used as a drug of last resort when battling resistant bacterial strains. Klebsiella pneumonia tends to affect people with underlying conditions, such as alcoholism. These medical tools and conditions may allow K. pneumoniae to enter the body and cause infection. It is clinically the most important member of the Klebsiella genus of Enterobacteriaceae.

In this experiment, Klebsiella Pneumoniae was stained in order to determine the strains shape, size, arrangement and motility. Klebsiella is a genus of Gram-negative, oxidase-negative, rod-shaped bacteria with a prominent polysaccharide-based capsule.. Klebsiella species are found everywhere in nature. In MacConkey Agar medium, the colonies of Klebsiella pneumoniae are pink colored due to the lactose fermentation which is of great importance in differentiating K. pneumoniae from other Bacteria present in the specimen, especially from Gram-positive bacteria and Salmonella species which are non–lactose fermentors and gives colorless colonies on MacConkey agar medium. Here's what you need to know. [citation needed] It is also known as Friedlander's bacillum in honor of Carl Friedländer, a German pathologist, who proposed that this bacterium was the etiological factor for the pneumonia seen especially in immunocompromised individuals such as people with chronic diseases or alcoholics. 2017 comb.

The bacteria remain susceptible to aminoglycosides and cephalosporins, varying degrees of inhibition of the beta-lactamase with clavulanic acid have been reported. El bacilo conocido ahora como Klebsiella también fue descrito por Carl Friedlander y durante muchos años el “bacilo de Friedlander” fue bien conocido como causa de una neumonía grave y a menudo fatal. [30][31][32], To prevent spreading Klebsiella infections between patients, healthcare personnel must follow specific infection-control precautions,[17] which may include strict adherence to hand hygiene (preferably using an alcohol based hand rub (60-90%) or soap and water if hands are visibly soiled. This phenomenon happens because the organism is producing a capsule. Klebsiella Pneumoniae. Sepsis and septic shock can follow entry of the bacteria into the blood. Das Bakterium zählt zu den schnellen Lactosefermentierern und ist Oxidase-negativ. Klebsiella pneumoniae are normally harmless bacteria that live in your intestines and feces, but they can be dangerous in other parts of your body. Capsule – Capsules are present in Klebsiella pneumoniae which can easily be demonstrated using India ink preparation, appear as a clear halo in a dark background.

For patients with an invasive device in their bodies, contamination of the device becomes a risk; neonatal ward devices, respiratory support equipment, and urinary catheters put patients at increased risk. Klebsiella pneumoniae subsp. 4. Also, the pH requirement varies as per the strain of Klebsiella pneumoniae. Klebsiella species are distributed in a wide variety of environments including: the gastrointestinal tract, clinical specimens, soil, water and grain. [8], In terms of the diagnosis of Klebsiella pneumonia the following can be done to determine if the individual has this infection, including susceptibility testing for (ESBL) Extended Spectrum β-Lactamase, as well as:[10][8], Treatment for Klebsiella pneumonia is by antibiotics such as aminoglycosides and cephalosporins, the choice depending upon the person's health condition, medical history and severity of the disease. These include hyperproduction of ampC beta-lactamase with an outer membrane porin mutation, CTX-M extended-spectrum beta-lactamase with a porin mutation or drug efflux, and carbapenemase production. Klebsiellae grow well on ordinary media to optimal temperature of 37°C in 18-24 hours. These patients have an increased tendency to develop lung abscess, cavitation, empyema, and pleural adhesions.
