Is Acinetobacter Radioresistens Gram positive or negative?

Acinetobacter species are non-fermentative Gram-negative coccobacilli that are ubiquitous in the environment. The archetype pathogen within the genus is Acinetobacter baumannii, however, other species have the potential to cause human infection, especially in the hospital setting.

Where is Acinetobacter Radioresistens found?

Acinetobacter radioresistens is a non–spore forming, aerobic gram-negative coccobacillus. Biochemically, it does not ferment lactose and is catalase positive and oxidase negative. Acinetobacter is ubiquitous in soil and water. It has also been found in stool and river water and on vegetables, pillows, and head lice.

What is the drug of choice for Acinetobacter?

Polymyxins are the main therapeutic options for extensively drug-resistant Acinetobacter. Certain tetracyclines (minocycline and tigecycline) may also have a role.

What antibiotics cover Acinetobacter?

Carbapenems (imipenem, meropenem, doripenem) are the mainstay of treatment for A. baumannii, though carbapenem-resistant Acinetobacter strains have increasingly been reported worldwide in recent years.

How serious is Acinetobacter?

The CDC considers Acinetobacter, including A. baumannii, a serious public health threat because it’s often resistant to multiple antibiotics. In fact, 63 percent of Acinetobacter strains are multidrug-resistant, the CDC notes.

What infections does Acinetobacter cause?

Acinetobacter baumannii can cause infections in the blood, urinary tract, and lungs (pneumonia), or in wounds in other parts of the body. It can also “colonize” or live in a patient without causing infections or symptoms, especially in respiratory secretions (sputum) or open wounds.

Can a healthy person get Acinetobacter?

Acinetobacter poses very little risk to healthy people. People who have weakened immune systems, chronic lung disease, or diabetes are more susceptible to Acinetobacter infection.

What disease does Acinetobacter cause?

The Acinetobacter superbug can cause diseases such as pneumonia and meningitis. Acinetobacter baumannii is a bacterium that can cause a range of diseases. It typically infects people inside a healthcare facility — doctors refer to these as “nosocomial” infections.

What causes Acinetobacter infection?

Acinetobacter can live for long periods of time on environmental surfaces and shared equipment if they are not properly cleaned. The germs can spread from one person to another through contact with these contaminated surfaces or equipment or though person to person spread, often via contaminated hands.

How did I get Acinetobacter?

Acinetobacter is spread by contact with a person or environment that has the bacteria. In healthcare facilities, the bacteria can spread from workers’ hands or contaminated surfaces or healthcare items.

What are the symptoms of Acinetobacter?

What are the signs and symptoms of an Acinetobacter baumannii infection?

  • Fever.
  • Red, swollen, warm, or painful skin areas or wounds.
  • An area of orange, bumpy skin with blisters.
  • Cough, chest pain, or trouble breathing.
  • Burning feeling while you urinate.
  • Sleepiness, headaches, or a stiff neck.

How do you get Acinetobacter?

Why is accurate identification of Acinetobacter radioresistens important for clinical management?

Therefore, accurate identification of A. radioresistensis important for clinical management and to potentially prevent the spread of carbapenem resistance. Keywords: Acinetobacter radioresistens, Bacteremia, MALDI-TOF MS, OXA-23, Pneumonia

What is the substrate of Acinetobacter radioresistens S13?

Acinetobacter radioresistens S13, able to grow on phenol or benzoate as sole carbon and energy sources, has been capable to produce biodegradation kinetics for mixtures of acetate, benzoate, and phenol: the substrate utilization benzoate >acetate >phenol, showed that benzoate was the preferred substrate. 7.5.

Is Acinetobacter radioresistensis a carbapenemase?

Acinetobacter radioresistensis the source of the Class D OXA-23 carbapenemase that can confer carbapenem resistance in A. baumannii. Therefore, accurate identification of A. radioresistensis important for clinical management and to potentially prevent the spread of carbapenem resistance.

Can Acinetobacter radioresistens ustb-04 utilize methyl parathion?

The bacterium was identified as Acinetobacter radioresistens USTB-04, showed the ability to utilize 1200 mgL-1 of methyl parathion within less than four days. Moreover, some Pseudomonas strains isolated from tea rhizosphere showed the biodegradation of propiconazole (triazole fungicide) ( Sarkar et al., 2009 ).
