Overview
Mycobacterium abscessus is a rapidly growing mycobacterium (RGM) that is a common water contaminant. Mycobacterium abscessus is a bacterium distantly related to the ones that cause tuberculosis and leprosy. It is part of a group known as rapidly growing mycobacteria and is found in water, soil, and dust. It has been known to contaminate medications and products, including medical devices. M. abscessus can cause a variety of infections. Healthcare-associated infections due to this bacterium are usually of the skin and the soft tissues under the skin. It is also a cause of serious lung infections in persons with various chronic lung diseases, such as cystic fibrosis, post-traumatic wound infections, and disseminated cutaneous diseases, mostly in patients with suppressed immune systems.
Historical Perspective
Mycobacterium abscessus was first isolated in 1953 from gluteal abscesses in a 62-year-old patient who had injured her knee as a child and had a disseminated infection 48 years later.[1] It was until 1992 that Mycobacterium abscessus is considered a separate organism from Mycobacterium chelonae.
The species M. bolletii, named after the late microbiologist and taxonomist Claude Bollet, was described in 2006. In current taxonomy, M. bolletii and M. massiliense (named for Massilia, the ancient Greek and Roman name for Marseille, where the organism was isolated) have been incorporated into M. abscessus subsp. bolletii. [2]
Classification
Pathophysiology
Pathogen
Mycobacterium abscessus is a bacterium distantly related to the ones that cause tuberculosis and leprosy. It is part of a group known as rapidly growing mycobacteria and is found in water, soil, and dust. It has been known to contaminate medications and products, including medical devices.
Mycobacterium abscessus is relatively resistant to chlorine and standard desinfectant.[5]
Transmission
Infection with M. abscessus is usually caused by injections of substances contaminated with the bacterium or through invasive medical procedures employing contaminated equipment or material. Infection can also occur after accidental injury where the wound is contaminated by soil. There is very little risk of transmission from person to person.
Microscopy
- Gram-positive, nonmotile and acid-fast rods (1.0-2.5µm x 0.5µm).
Colony characteristics
- Colonies on Löwenstein-Jensen media may occur as smooth as well as rough, white or greyish and nonphotochromogenic.
Physiology
- Growth at 28°C and 37°C after 7 days but not at 43°C.
- On MacConkey agar at 28°C and even 37°C.
- Tolerance to 5% NaCl and 500mg/l hydroxylamine (Ogawa egg medium) and 0.2% picrate (Sauton agar medium).
- Positive degradation of p-aminosalicylate.
- Production of arylsulfatase but not of nitrate reductase and Tween 80 hydrolase.
- Negative iron uptake test. No utilisation of fructose, glucose, oxalate and citrate as sole carbon sources.
Differential characteristics
- M. abscessus and M. chelonae can be distinguished from M. fortuitum or M. peregrinum by their failure to reduce nitrate and to take up iron.
- Tolerance to 5% NaCl in Löwenstein-Jensen media tolerance to 0.2% picrate in Sauton agar and non-utilisation of citrate as a sole carbon source are characteristics that distinguish M. abscessus from M. chelonae.
- M. abscessus and M. chelonae sequevar I share an identical sequence in the 54-510 region of 16S rRNA, However, both species can be differentiated by their hsp65 or ITS sequences
Strains
ATCC 19977 = CCUG 20993 = CIP 104536 = DSM 44196 = JCM 13569 = NCTC 13031
Genetics
A draft genome sequence of M. abscessus subsp. bolletii BDT was completed in 2012.[6] More than 25 different strains of this subspecies, including pathogenic isolates, have had their genomes sequenced.[7]
Resistance to Antibiotics
Intrinsic Factors
- The permeability barrier of the envelope of the myobacterium[8]
- Low affinity of the antibiotics to their target[8]
- Drug export systems[8]
- Neutralization of the antibiotics by cytoplasmic enzymes[8]
Acquired Factors
- Mutation of the genes that code the antibiotic targets[8]
Risk Factors
Mycobacterium abscessus infecttion has been reported in the following cases:
Skin and Soft Tissue Infection
- Open wounds
- Surgical tourism[9]
- Laparoscopic surgery[9]
- Cosmetic surgery[10]
- Intramuscular injections[11][12][13][14]
- Inappropriate skin disinfection
- Inappropriate sterilization of the equipment[15]
- Contaminated solutions
- Contaminated municipal or water supply[5]
- Acupuncture (contaminated solution used to clean the physical therapy device)[16]
- Dialysis[17][18]
- Bronchoscopy[5]
- Inadequate desinfection of the bronchoscope
- Contaminated local anesthesia solution
- Contaminated tap water
- Contaminated antimicrobial solution
Bronchopulmonary Infection
- Chronic lung disease (for example, cystic fibrosis)[19][20]
- Previously untreated mycobacterial infection
- Co-existent mycobacterium avium complex infection
- Chronic vomiting
- AIDS/HIV (not a common infection in this population)[21]
Disseminated Infection
Natural History, Complications and Prognosis
Infection with Mycobacterium abscessus can lead to:
- Skin and soft tissue infection
- Open wound infection
- Sternal wound infection[24]
- Bronchopulmonary infection[8]
- Disseminated infection in immunocompromised patients[8]
- Other rare infections
Mycobacterium abscessus is reported in many health-care associated infections. A history of Mycobacterium abscessus infection is a contraindication for lung transplantation.[8]
Mycobacterium abscessus is the most common non tuberculosis mycobacterial infection in cystic fibrosis.[19] Chronic infection with Mycobacterium abscessus is associated with a decline in lung function among patients with cystic fibrosis.[27] The most commonly reported symptom is cough. Constitutional symptoms increase as the disease progresses. The only effective long-term therapy for Mycobacterium abscessus was reported to be surgical resection of the localized disease.[28] Death may occur in these patients (mortality in ~14% of patients) due to respiratory failure secondary to the progressive lung disease.[28]
Diagnosis
History
The patient should be asked about any recent history of procedures, such as surgery or injections.
Symptoms
Symptoms of Skin and Soft Tissue Infection
Symptoms of Pulmonary Infection
- Cough[28]
Constitutional Symptoms
Physical Examination
Skin
- Skin infected with M. abscessus is usually red, warm, tender to the touch, swollen, and/or painful.
- Infected areas can also develop boils or pus-filled vesicles.
Laboratory Studies
To reach a definitive diagnosis, the organism has to be cultured from the infection site or, in severe cases, from a blood culture. The diagnosis is made by growing this bacterium in the laboratory from a sample of the pus or biopsy of the infected area.
Chest X-Ray
Patients with pulmonary Mycobacterium abscessus infection might have the following on chest X-ray:[28]
- Upper lobe infiltrates
- Bilateral involvement of the lungs
- Cavitation
Diagnostic Criteria for Pulmonary Mycobacterium Abscessus
The diagnosis of mycobacterium abscessus requires the presence of clinical and microbiological criteria.
Clinical Diagnostic Criteria
- Pulmonary symptoms, OR
- Cavitation or nodular opacities on chest X-ray, OR
- Multifocal bronchiectasis with multiple small nodules on HRCT scan
AND
- Other diagnoses, such as tuberculosis, are ruled out
Microbiological Diagnostic Criteria
- Positive culture from ≥2 different expectorated sputum samples
OR
- Positive culture from ≥1 bronchial wash or bronchial lavage
OR
- Histopathologic features of mycobacterial infection in transbronchial or lung biopsy AND positive culture for mycobacterium abscessus
Treatment
Medical Therapy
The recommended treatment strategy is to combine three drugs
2. Amikacin or another aminoglycoside
3. An injectable agent such as either cefoxitin or imipenem
Surgical Treatment
Treatment of infections due to M. abscessus consists of draining collections of pus or removing the infected tissue and administering the appropriate combination of antibiotics for a prolonged period of time. Infection with this bacterium usually does not improve with the usual antibiotics used to treat skin infections. Testing the bacteria against different antibiotics is helpful in guiding doctors to the most appropriate treatment for each patient.
Primary Prevention
- Anyone who touches or cares for the infected site should wash their hands carefully with soap and water.
- Patients should follow all instructions given by their healthcare provider following any surgery or medical procedure.
- Avoid receiving procedures or injections by unlicensed persons.
