| ==Overview== | | ==[[Mycobacterium abscessus overview|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.

| ''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.<ref name="pmid13035193">{{cite journal| author=MOORE M, FRERICHS JB| title=An unusual acid-fast infection of the knee with subcutaneous, abscess-like lesions of the gluteal region; report of a case with a study of the organism, Mycobacterium abscessus, n. sp. | journal=J Invest Dermatol | year= 1953 | volume= 20 | issue= 2 | pages= 133-69 | pmid=13035193 | doi= | pmc= | url=http://www.ncbi.nlm.nih.gov/entrez/eutils/elink.fcgi?dbfrom=pubmed&tool=sumsearch.org/cite&retmode=ref&cmd=prlinks&id=13035193 }} </ref> 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''. <ref> Etymologia: Mycobacterium abscessus subsp. bolletii. Emerg Infect Dis [Internet]. 2014 Mar [February 20, 2014]. http://dx.doi.org/10.3201/eid2003.ET2003 </ref>

| ===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.<ref name="pmid9891805">{{cite journal| author=Wallace RJ, Brown BA, Griffith DE| title=Nosocomial outbreaks/pseudo-outbreaks caused by nontuberculous mycobacteria. | journal=Annu Rev Microbiol | year= 1998 | volume= 52 | issue= | pages= 453-90 | pmid=9891805 | doi=10.1146/annurev.micro.52.1.453 | pmc= | url=http://www.ncbi.nlm.nih.gov/entrez/eutils/elink.fcgi?dbfrom=pubmed&tool=sumsearch.org/cite&retmode=ref&cmd=prlinks&id=9891805 }} </ref>
| |
| | |
| ===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

| ====Symptoms of Skin and Soft Tissue Infection====
| |
| * Red, warm, tender to the touch, swollen, and/or painful [[skin]]
| |
| * [[Boil]]s

| * Pus-filled [[vesicle]]s

| |
| | |
| ====Constitutional Symptoms====
| |
| *[[Fever]]
| |
| *[[Chills]]
| |
| *[[Muscle aches]]
| |
| *[[Malaise]]
| |
| | |
| ===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]]:<ref name="pmid8484642">{{cite journal| author=Griffith DE, Girard WM, Wallace RJ| title=Clinical features of pulmonary disease caused by rapidly growing mycobacteria.

| |
| * Upper lobe infiltrates
| |
| * Bilateral involvement of the lungs
| |
| * Cavitation
| |
| | |
| ==Diagnostic Criteria==
| |
| 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== | | ==Treatment== |
| ===Medical Therapy===
| | [[Mycobacterium abscessus medical therapy|Medical Therapy]] | [[Mycobacterium abscessus surgery|Surgery]] | [[Mycobacterium abscessus primary prevention|Primary Prevention]] |
| The recommended treatment strategy is to combine three drugs
| |
| | |
| 1. [[Clarithromycin]]
| |
| | |
| 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.
