What does a positive gelatinase test mean?
Positive: Partial or total liquefaction of the inoculated tube (the control tube must be completely solidified) at 4°C within 14 days. On plates, gelatin hydrolysis is indicated by clear zones around gelatinase-positive colonies. Negative: Complete solidification of the tube at 4°C.
What diseases does Providencia cause?
The genus Providencia includes urease-producing gram-negative bacilli that are responsible for a wide range of human infections. Although most Providencia infections involve the urinary tract, they are also associated with gastroenteritis and bacteremia. Providencia infections are uncommon and are usually nosocomial.

What bacteria produces gelatinase?
Gelatinases are expressed in several bacteria including Pseudomonas aeruginosa and Serratia marcescens. In humans, the gelatinases are matrix metalloproteinases MMP2 and MMP9.
Does Providencia stuartii require isolation?
If an indwelling device is required, meticulous care of such devices is important in reducing the likelihood of colonization and infection. Providencia species are rarely isolated in uncomplicated urinary tract infections.
Is Providencia stuartii Gram positive or negative?

What does a Gram stain tell you about bacterial infection?
If you have a bacterial infection, the Gram stain will determine what kind of medication you need. Read on to learn about gram-positive bacteria and their associated diseases, along with typical treatments. The hallmark trait of gram-positive bacteria is their structure. Generally, they have the following characteristics: No outer membrane.
Why do Gram positive and negative bacteria stain purple?
This chemical dye can stain thick peptidoglycan layers. Under a microscope, gram-positive bacteria appear purple-blue because their thick peptidoglycan membrane can hold the dye. The bacteria is called gram-positive due to the positive result. Gram-negative bacteria stain pink-red.
