BACTE LEC: ME KLEBSIELLA Flashcards
This bacterial genus belongs to the Enterobacteriaceae family and includes at least four species.
Klebsiella
A species of Klebsiella that is a common pathogen in animals.
Klebsiella pneumoniae
This bacterium is an occasional commensal in the intestine but rarely causes disease there.
Klebsiella pneumoniae
Klebsiella pneumoniae can invade the reproductive tract of these animals.
Mares, cows, bitches
A historical synonym for Klebsiella pneumoniae.
Friedlander’s bacillus
This disease in foals is caused by Klebsiella pneumoniae and involves pus formation.
Suppurative infections
A condition in mares caused by Klebsiella pneumoniae that affects the uterus.
Metritis
This material, often used as bedding for cattle, is associated with Klebsiella-related mastitis outbreaks.
Wood shavings
The staining reaction and morphology of Klebsiella species.
Gram-negative, encapsulated rods
Klebsiella species are distinguished from other Enterobacteriaceae by their lack of this motility structure.
Flagella
Klebsiella colonies on agar appear as moist, spreading, and very viscous due to this feature.
Capsule production
This biochemical test for glucose fermentation is positive in Klebsiella due to a plasmid-encoded trait.
Lactose fermentation
A facultative anaerobic trait of Klebsiella, indicated by negative oxidase test and use of tartrate and malonate.
Oxidase negative, tartrate and malonate positive
Klebsiella pneumoniae produces this gas and enzyme, both of which are useful for its identification.
Hydrogen sulfide (H2S) and urease
This antigenic structure of Klebsiella consists of at least 82 capsular types.
Capsular antigen (K antigen)
This antigen type in Klebsiella is composed of heat-stable polysaccharides.
Capsular antigen
Klebsiella pneumoniae infections are common in these hospital-acquired cases in small animals.
Nosocomial infections
A severe infection caused by Klebsiella in dairy cows, often within a few days of calving.
Coliform mastitis
A common symptom of Klebsiella mastitis in cows, characterized by swelling, redness, and fluid secretion.
Udder hyperemia and edema
Klebsiella pneumoniae strains found in mares with metritis predominantly belong to these capsular types.
Capsular types 1, 5, and 7
Infected stallions can transmit Klebsiella pneumoniae to mares, but they usually clear the infection within this time frame.
10-12 days
This antibiotic is usually ineffective against Klebsiella due to intrinsic resistance.
Ampicillin
This beta-lactam antibiotic is commonly used for treating Klebsiella-related urinary tract infections in dogs.
Cephalexin
The diagnostic feature of Klebsiella on agar plates, characterized by its very mucoid colony form.
Encapsulated, mucous-like colonies
A zoonotic species of Klebsiella that can cause respiratory infections in humans.
Klebsiella pneumoniae
Klebsiella pneumoniae is often associated with this life-threatening complication in humans.
Hospital-acquired pneumonia
Klebsiella infections in humans are commonly linked to this predisposing factor.
Immunosuppression
Klebsiella pneumoniae is a major cause of this type of wound infection in surgical patients.
Nosocomial surgical site infections
The presence of this virulence factor allows Klebsiella to evade the immune response.
Polysaccharide capsule
A laboratory test that detects the presence of Klebsiella’s mucoid capsule.
String test
Klebsiella pneumoniae is commonly found in these environments outside of a host.
Soil and water
This enzyme produced by some Klebsiella strains leads to resistance against carbapenems.
Carbapenemase
Klebsiella pneumoniae is often implicated in this severe lung condition in humans.
Necrotizing pneumonia
The presence of hypermucoviscosity in Klebsiella is associated with this syndrome.
Hypervirulent Klebsiella syndrome
Klebsiella species can cause this type of liver abscess in immunocompromised patients.
Pyogenic liver abscess
One of the main reservoirs for Klebsiella in veterinary hospitals.
Contaminated medical equipment
Klebsiella can be transmitted to humans through direct contact with this.
Contaminated surfaces
This metabolic test differentiates Klebsiella from E. coli due to a negative result.
Methyl red test
Klebsiella is positive for this biochemical test that detects acetoin production.
Voges-Proskauer test
The ability to ferment lactose makes Klebsiella appear in this color on MacConkey agar.
Pink colonies
Klebsiella infections in the urinary tract can lead to this condition in dogs.
Cystitis
Klebsiella pneumoniae is commonly involved in this reproductive disorder in cows.
Endometritis
Klebsiella species have been associated with severe outbreaks of this disease in goats.
Pneumonia
This type of inflammation is commonly seen in Klebsiella infections of the lungs.
Fibrinosuppurative pneumonia
The natural habitat of Klebsiella, where it can persist outside of a host for extended periods.
Soil and decaying vegetation
Severe cases of Klebsiella pneumoniae infection in cows may lead to this outcome.
Septicemia
This term describes the tendency of Klebsiella colonies to produce thick, sticky mucus.
Hypermucoviscosity
Klebsiella pneumoniae is a known cause of this severe post-partum condition in cows.
Coliform mastitis
Wood-based bedding materials in dairy farms may harbor high levels of this bacterium.
Klebsiella pneumoniae
Klebsiella has been isolated from infections in these small companion animals.
Dogs and cats
This test determines the ability of Klebsiella to resist serum bactericidal activity.
Serum resistance assay
The ability of Klebsiella to cause severe systemic infections is linked to this resistance trait.
Multidrug resistance
This environmental factor contributes to an increase in Klebsiella populations in sawdust bedding.
Moisture
Klebsiella’s capsule allows it to avoid this immune system defense mechanism.
Phagocytosis
