What is Carba NP test?

What is Carba NP test?

The Carba NP test (CNPt) is a biochemical test for rapid detection (≥2 h) of carbapenemase production on Gram-negative bacilli (1). It is based on in vitro hydrolysis of imipenem by a bacterial lysate, which is detected by changes in pH values using the indicator phenol red (red to orange/yellow).

Which is the most recommended test for detection of carbapenemase production?

Modified Hodge test: A simple and effective test for detection of carbapenemase production.

What is modified carbapenem inactivation method?

Modified Carbapenem Inactivation Method In the mCIM, 1 μL loopfuls of Enterobacteriaceae or 10 μL loopfuls of P. aeruginosa or A. baumannii from blood agar plates was emulsified in 2 mL trypticase soy broth (TSB). A meropenem disk was then immersed in the suspension and incubated for a minimum of 4 h at 35°C.

What is modified Hodge test?

The modified Hodge test (MHT) is a phenotypic screening test to identify carbapenemase producers, being recommended by the Clinical and Laboratory Standards Institute (CLSI) for Enterobacteriaceae with elevated carbapenem MICs or reduced disk diffusion inhibition zones (2).

What is Carba?

Carba mix contains the following three allergens: Diphenylguanidine, Zincdibutyldithiocarbamate, and Zincdiethyldithiocarbamate. These chemicals are used as fungicides and pesticides, and also in the manufacture of many rubber products.

Which antimicrobial is recommended for confirmation of carbapenemase production?

Ertapenem has been recommended as the best screening agent for KPC detection because KPC producers are usually insusceptible to ertapenem, but may remain susceptible to other carbapenems.

What is Carba mix used in?

Carba Mix combines three chemicals: 1,3-Diphenylguanidine (DPG), Zinc Dibutyldithiocarbamate (ZBC) and Zinc Diethydithiocarbamate (ZDC). These chemicals are used in adhesives, animal repellents, condoms, cosmetic applicators gloves, medical devices, fungicides, leather shoes, textile, swimwear, tires and tubes.
