Bacteria that do not use carbohydrates for energy and are gram-negative rods.

NF bacteria that can cause infection in immunocompromised individuals.

Microorganisms that cannot ferment carbohydrates.

Organisms that need oxygen for survival.

A test indicating the presence of cytochrome c oxidase, a protein essential for aerobic respiration in some bacteria.

Gram-negative bacteria characterized by their oxidative metabolism and motility.

Pseudomonas move using a single flagellum at a pole of the cell.

Pseudomonas break down glucose by oxidation (not fermentation).

A gram-negative, rod-shaped bacterium often found in soil and water, capable of causing opportunistic infections.

Pseudomonas uses oxygen to break down nutrients for energy.

A substance produced by some Pseudomonas strains that contributes to their mucoid (sticky) colony appearance.

A yellow pigment produced by Pseudomonas aeruginosa, detectable only under UV light.

A blue pigment produced by Pseudomonas aeruginosa, especially in low-iron environments.

A bacterium that causes disease primarily when the host's defenses are weakened.

Pseudomonas colonies can be smooth, flat, elevated, or mucoid, and sometimes have a metallic sheen, blue-green pigment, or a sweet fruity odor.

Pseudomonas secrete enzymes that break down host tissue and aid in infection.

Pseudomonas infections typically involve attachment, local invasion, and systemic spread through the blood.

Pseudomonas aeruginosa exhibits resistance to certain antibiotics.

Putida bacteria's ability to break down pollutants like oil and toluene.

Adherent, wrinkled or leathery, hard and dry colonies, sometimes yellowish or brownish.

Can grow from 4°C to 45°C, optimally at 35°C.

25 DNA homology groups, several species named including baumannii, iwoffi, haemolyticus, ubiquitous in environments.

Soil, water, food, hospitals & medical equipment.

Common on skin and pharynxes of 25% & 7% of adults, respectively. Easily colonizes hospitalized patients.

A. baumannii is quite pathogenic, A. iwoffi is less pathogenic.

Associated with various health issues including UTIs, pneumonia, endocarditis, and septicemia.

Strictly aerobic, gram-negative coccobacilli, oxidase negative, catalase positive, non-motile.

25°C

A gram-negative bacterium known for producing biofilms, resisting disinfectants, and exhibiting multi-drug resistance.

The ability of a microorganism to survive and grow even in the presence of multiple antibiotics.

A community of microorganisms, often in complex mixtures, that adhere to a surface and are protected by an extracellular matrix.

A gram-negative, non-fermenting bacterium that causes infections, often in hospital settings.

A pathogen that is responsible for infections that are acquired in a healthcare setting.

Produces a K/NC reaction, primarily beta-hemolytic. Important for recognizing the organism.

Rapid oxidation of maltose, but weaker for glucose; used to identify Stenotrophomonas maltophilia.

Common cause of infections in immunocompromised patients and frequently present in medical devices.

Procedures implemented for minimizing the spread of contagious organisms through direct or indirect contact.

A laboratory test to determine the effectiveness of different antibiotics against a specific microorganism.Crucial in guiding treatment.

Presence in urine often due to urinary catheter use or manipulation; can also be found in wounds but usually a colonizer, unless associated with WBCs as indicative of inflammation

Intrinsically resistant to many antibiotics; due to beta-lactamases, carbapenemases, plasmids, altered OM proteins, and efflux mechanisms, readily develops antibiotic-resistance.

A mix of 9 subspecies known as GNB (gram-negative bacteria) frequently associated with cystic fibrosis patients; inhabits soil and water, not normal microbiota.

Grows on sheep blood agar, and other standard media; shows delayed, but eventual, oxidation of lactose changing color to pink/red after 4-7 days; identified by differential media like BCSA or OFPBL

Weakly oxidative; decarboxylates lysine; oxidizes glucose, maltose, and lactose; DNAse negative; negative arginine reactions differentiate it from certain Burkholderia.

B. cepacia oxidizes mannitol; S. maltophilia is DNAse positive. This helps distinguish them.

Strict precautions, including standard and contact precautions, needed for management. Antimicrobial therapy often requires a combination of drugs like rifampin, fluoroquinolone or beta-lactam, tailored to the specifics of the infection. Susceptible to TMP-SXT, Colistin and Polymyxin B.
