Enterobacteriaceae
Klebsiella
Classification
Klebsiella pneumoniae
Klebsiella oxytoca
clinical significance
causative factors
Capsule, lipopolysaccharide, adhesin, siderophore
Pathogenic type
Klebsiella pneumoniae classic
Less toxic, nosocomial infections
Pneumonia, urinary tract infection, abdominal infection, sepsis
Highly toxic~
Highly toxic, poor health and immunity
With primary liver abscess as the main symptom, the thicker the capsule, the stronger the virulence, the stronger the mucus, and the drug resistance is lower than that of CKP.
biological properties
Morphology
G-bacillus, short or club, single, paired
No flagella, no spores, obvious capsule
nutritional properties
Not high nutritional requirements
Mucous colonies, easy to fuse and stir up the inoculation loop into long filaments
Blood plate: off-white, larger, round, moist, mucous colonies
drug resistance
Natural resistance: ampicillin
Enzyme-producing strain: carbapenem-resistant Enterobacteriaceae (CRE))
microbiology test
specimen collection
Abscess drainage fluid, respiratory specimens, blood, urine
Testing method
Kinetic negative, ornithine decarboxylase negative, KIA (AA -), IMVIC (-- )
Proteus
Classification
strange
ordinary
clinical significance
Pathogenic factors: pili, flagella, urease, endotoxin
Type of disease: urinary tract infection
biological properties
Morphology
G-, scattered arrangement, polymorphism
There are peripheral flagella and active movement
No spores, no capsule
Cultivation characteristics
The nutritional requirements are not high and it can withstand low temperatures of 10-43 degrees Celsius.
Ordinary plates and blood plates: corrugated film-like growth - migratory growth (flagella); inhibitors or increasing agar concentration can inhibit migratory growth
Enteral selection plates (MAC): colorless (non-fermentable lactose), translucent, round, flat
SS plate: The center of the colonies of hydrogen sulfide-producing strains is black
drug resistance
Natural drug resistance: tigecycline, polymyxotoxin, nitrofurantoin
Enzyme-producing strains: ESBLs
microbiology test
Specimen collection: urine, wound secretions, respiratory specimens, blood
Testing method
Phenylalanine deaminase, urease test, KIA: KA
