Symptoms of chronic rhinosinusitis (CRS) often persist despite treatment. Because nontuberculous mycobacteria (NTM) are resistant to commonly used antimicrobial drugs and are found in drinking water that patients may use for sinus irrigation, we investigated whether some CRS patients were infected with NTM in New York, New York, USA, during 2001-2011. Two approaches were chosen: 1) records of NTM-infected CRS patients were reviewed to identify common features of infection and Mycobacterium species; 2) samples from plumbing in households of 8 NTM-infected patients were cultured for NTM presence. In 3 households sampled, M. avium sharing rep-PCR and pulsed field gel electrophoresis fingerprints identified M. avium isolates clonally related to the patients' isolates. We conclude that patients with treatment-resistant CRS may be infected with NTM and should have cultures performed for NTM so appropriate therapy can be instituted. In addition, the results suggest that CRS patients can be infected by NTM in their household plumbing.

A subset of patients with chronic rhinosinusitis (CRS) often experience persistent symptoms, despite undergoing many medical and surgical modes of treatment. Current theories regarding the cause of CRS include immunologic reactions to microorganisms (1,2). Even though they receive various treatments, including antimicrobial drugs and sinus irrigation, many patients continue to be symptomatic (2). One possible reason for the persistence of symptoms is the presence of microorganisms that are resistant to typically prescribed antimicrobial drugs, for example, nontuberculous mycobacteria (NTM).

Recovery of NTM from the sinus cavity has been documented in 19 patients, including those with cystic fibrosis (3), HIV infection (410), and diabetes (11). NTM isolation from the sinus cavity has been rarely reported in immunocompetent, nondiabetic patients who do not have cystic fibrosis (1215). One case of infection with NTM is documented in a study by Spring and Miller (14). The patient had a 21-year history of rhinosinusitis and exhibited left maxillary facial pain, nasal discharge, and congestion. Mycobacterium chelonae, Staphylococcus aureus, and Pseudomonas aeruginosa were recovered from sinus cultures. Successful treatment ultimately required a 3-year course of multiple intravenous antimicrobial drug combinations and subsequent sinus operations (14). Recently, a new member of the M. abscessus-chelonae complex, M. franklinii, was isolated from patients in the northeastern United States who have chronic sinusitis (16).

NTM are environmental opportunistic pathogens found in natural and human-engineered waters, including drinking water distribution systems (17) and household plumbing (1820). NTM species can be classified into 2 groups on the basis of growth rates; rapidly growing mycobacteria (e.g., M. chelonae and M. abscessus) form colonies in <7 days at 37°C, and slowly growing mycobacteria (e.g., M. avium and M. intracellulare) take >7 days at 37°C to form colonies. Because NTM are resistant to commonly used antimicrobial drugs (21) and are found in drinking water, they might be responsible for antimicrobial drug–resistant, chronic rhinosinusitis. We report the isolation, identification, and fingerprinting of NTM isolates from patients with CRS and from their household plumbing.

Patient Histories

We reviewed the charts of 33 adult outpatients in whom CRS was diagnosed in the medical practice of W.S. Tichenor, whose endoscopically directed sinus cultures yielded NTM. The 33 represent ≈1% of patient samples collected over a 10-year period. In all patients, CRS had been diagnosed on the basis of a combination of initial evaluation; appearance of the sinuses by endoscopic examination; results of computed tomographic scan; and endoscopically directed cultures for bacteria, fungi, and NTM. From all patients, bacterial isolates had been cultured at the time of endoscopy.

Initial symptoms, NTM identity, surgical history, HIV status, cystic fibrosis history and carrier status, diabetes and immune-deficiency status, current nasal irrigations, presence of polyps, treatment, repeat culture results, and symptom reduction were assessed (Table 1). Common patient conditions at the time of nasal endoscopy included headache, nasal blockage or congestion, thick postnasal drip, and decreased ability to taste or smell. Thirty (91%) of the 33 patients had previously undergone endoscopic sinus surgery; 10 (30%) had histories of primary immunodeficiency. Twelve (36%) of the 33 patients had evidence of polyps at the time of nasal endoscopy; however, no clear association was found between NTM species and the presence of polyps. Thirty-one (94%) of 33 patients were using some form of nasal irrigation at the time of endoscopy. Of those, 26 were known to have used tap water to irrigate the sinuses.

Patient Sample Collections

Endoscopically directed samples were taken directly from the sinuses, middle meatus, or ostiomeatal unit by using a flexible catheter with a self-contained Lukens trap as described (22). Samples (0.5–3 mL) were sent to the microbiology laboratories (Mayo Medical Laboratories, Rochester, MN, USA; Specialty Laboratories, Valencia, CA, USA; Quest Laboratories, Peterboro, NJ, USA) in sterile 5-mL containers.

Household Collections

Members of households with occupants who had NTM-associated CRS volunteered to participate in studies of their households’ water systems. Informed consent was obtained from each collaborating patient, and the study was reviewed by the Virginia Tech Institutional Research Board and granted exempt status. NTM isolates from the patients were obtained through laboratories that cultured NTM from endoscopy samples. Containers, swabs, and tubes were sent to each collaborating patient’s household. Directions were provided for the collaborating patient or family member to collect hot and cold water samples (500 mL) and biofilms/sediment from water taps and showerheads. Biofilm samples were collected by swabbing the inside of taps and showerheads, and swab specimens were placed in tubes containing 2 mL of tap water (from Blacksburg, VA, USA), sterilized by autoclaving. If in-line or point-of-use water filters were submitted by the patients, a 4-cm2 area was swabbed, and the swab was placed in 2 mL of sterile tap water.

NTM Isolation, Identification, and Fingerprinting

Patient NTM isolates were identified by various methods, depending on the laboratory: DNA probe, high-performance liquid chromatography, gas-liquid chromatography, internal transcribed spacer region or 16S rDNA sequencing. NTM in water and swab (taps and filters) samples were enumerated and isolated as described (19). Household NTM isolates and those from patients were identified by nested PCR of 16S rRNA gene (23) and PCR amplification and analysis of restriction endonuclease digestion fragments of the hsp-65 gene (24). When the Mycobacterium species of the patient and household water system isolates were identical, isolates were fingerprinted by rep-PCR (25) and pulsed-field gel electrophoresis (PFGE) of AseI and XbaI restriction endonuclease digests of genomic DNA (26). To interpret PFGE in categories of “indistinguishable,” “closely related,” and “different,” we used previously described criteria for the evaluation of Mycobacterium avium complex isolates (27). With a minimum of 10 interpretable bands, strains were interpreted as indistinguishable (no band differences), closely related (1–3 band differences), possibly related (4–6 band differences), and different (>7 band differences). These isolates underwent species confirmation by sequencing of the internal transcribed spacer 1. M. intracellulare and M. chimaera are indistinguishable without gene/region sequencing (28).


Review of the charts of the 33 CRS patients showed that 39 NTM isolates belonging to 10 Mycobacterium species were recovered from samples from the ostiomeatal unit or paranasal sinuses (Table 2). The patients’ mycobacterial isolates were identified by Mayo Clinic, Quest, and Specialty Laboratories. Two different Mycobacterium species were isolated from 6 patient samples (Table 2). Most isolates (25 [64%] of 39) were rapidly growing mycobacteria, primarily M. abscessus or M. chelonae. One laboratory that received patient samples did not distinguish M. abscessus from M. chelonae. The predominant slowly growing Mycobacterium species was MAC (6 [15%] of 39). M. gordonae was isolated from 4 (12%) of the 33 patients. Although the organism is normally considered a saprophyte, M. gordonae infection has been reported in immunodeficient persons (2931), and thus its isolation should not be dismissed.

NTM Isolates from Households of Current CRS Patients

A total of 80 samples (i.e., 43 water, 31 biofilm, and 6 from filters) for NTM isolation were received from the 8 collaborating CRS patients. NTM were isolated from water, biofilm, or filter samples from at least 1 sample from 5 (63%) of the 8 households sampled and from 35 (40%) of the 80 samples (Table 3). The frequency of NTM recovery from water (44%), biofilm (42%), and filter (50%) samples was not significantly different (p = 0.6065, Kruskal-Wallace test). NTM colony counts varied widely in samples from the different households (Table 4). In 4 households, at least 1 of the samples yielded an NTM isolate that was of the same species and had the same rep-PCR fingerprint as that of the patient according to published criteria (25) (Figure 1). The band patterns illustrate the large number and wide range of rep-PCR bands and illustrate the discrimination provided by rep-PCR fingerprinting (25). To confirm the relatedness between isolates from patient and household plumbing, PFGE was performed (26) for the same isolates (Figure 2). The PFGE band pattern of the isolate from patient 2 and the pattern from the patient’s household (lanes 10 and 11) appear almost identical (“closely related”). The PFGE patterns for 2 isolates from the household of patient 5 were “indistinguishable” and are “closely related” (clonal) to the respective patient isolates and thereby clonal (Figure 2, panel A). Isolates from patient 8 and the patient’s household plumbing (not shown) gave faint signals by PFGE with repeat testing and both restriction enzymes. However, the patterns appeared “indistinguishable”(profile not shown). The lack of clear band patterns for the isolates from patient 8 and his or her household plumbing is likely because of the shared characteristic of resistance to lysis in the agar plugs (26). The absence of a match for patient 1 (not shown) might be because the person moved throughout the United States, and some places where the patient lived were not sampled. Samples of showerheads were collected from 6 of the 8 households, and although NTM isolates of the same species as that of the patient (i.e., M. avium) were recovered from 2 households, none of the showerhead isolates shared the same fingerprint with isolates from the patient. Notably, the samples from the household plumbing of the patients with M. gordonae and M. immunogenum isolates did not yield any NTM.


Our study confirms the possibility of the involvement of NTM in sinuses of patients with CRS (3,11,16). CRS patients who have not responded to medical treatment should undergo endoscopically directed sinus cultures for microorganisms, including fungi and NTM and other bacteria. Endoscopically directed sinus cultures have been shown to accurately replicate sinus puncture culture techniques (22). The American Thoracic Society and the Infectious Diseases Society of America discourage the use of swabs for sampling because swabs may decrease the likelihood of recovering NTM (21). Using a suction device to remove larger volumes of mucus helps increase the chances of obtaining representative sinus microflora (22). Spurious recovery of NTM, because of endoscope contamination, is possible (32), as is the possibility that glutaraldehyde may not adequately kill NTM (33). However, in the current study, endoscope contamination is an unlikely source of NTM because water samples from the physician’s office did not reveal NTM. In addition, the patient and household samples were processed in different laboratories.

Besides establishing NTM as a potential agent of CRS, our results strongly suggest that in 3 of the 8 CRS patients studied here, the household plumbing was the source of infection, on the basis of identity of rep-PCR fingerprints of patient and household isolates and their clonal relatedness as determined by PFGE. Clonal variation in Mycobacterium species isolates is characteristic of isolates recovered from household plumbing, but because single Mycobacterium species isolates are typically recovered from patient samples, DNA fingerprint matches are not always obtained (19,20). A study of persons with NTM pulmonary disease found that in 7 (41%) of 17 households, patient and household plumbing isolates were identical as shown by rep-PCR fingerprints (20). Because NTM are found in household tap water (19,20,34), CRS patients should avoid sinus irrigation with unsterilized tap water.

A major question concerning isolation of NTM from the sinus cavities of patients with CRS is whether NTM were involved in pathogenesis. No guidance exists for the diagnosis and treatment of NTM sinus infection. For pulmonary NTM disease, it is recommended that multiple cultures be obtained over time (21) to rule out transient colonization and avoid sampling deficiencies. Our experience suggests that multiple cultures may be necessary to find NTM because endoscopy samples from many patients will be found NTM positive only by 1 of 2–5 endoscopies. For example, 1 patient had cultures that yielded M. mageritense, but cultures obtained 1 week later were negative, even in the absence of antibacterial drug treatment. In addition, smears from 2 patients showed acid-fast bacilli, but cultures failed to yield any Mycobacterium species isolate; yet upon subsequent endoscopy, NTM were cultured. Several possible reasons could account for this low yield. First, hydrophobic NTM cells are likely adhering to the walls of the sinus cavity, and thereby a low number are in fluid removed during endoscopy. Second, the small volume of mucus removed at the time of culture also might reduce the likelihood of recovering NTM (22). Third, topical anesthetics, typically lidocaine, are used for anesthesia for endoscopy and might inhibit the growth of many microorganisms, including NTM (35). Although NTM could merely be colonizing the sinuses, several factors suggest otherwise. The samples that we collected were primarily mucus, and previously published reports on NTM in sinus samples from immunocompromised CRS patients were primarily based on biopsy specimens (3,6,15). In addition, our patients typically have persistent symptoms despite treatment with multiple different antimicrobial drug regimens over several months. Because the results of NTM culture and sensitivity testing take several months to obtain, patients are typically treated for other possible infecting microorganisms until the results of the NTM cultures are reported. Resolution typically occurred only after an extended course of multiple antimycobacterial agents given simultaneously. Unfortunately, the combination of insufficient experience and the absence of an established treatment protocol for CRS caused by NTM (21), prevent any meaningful review of treatment regimens for CRS caused by NTM. Such patients are treated with 2 oral antimycobacterial drugs and urged to irrigate sinuses with sterile or boiled water or saline, followed by irrigation with a topical antimycobacterial agent for 3–18 months, depending on clinical response and, in some cases, on subsequent positive cultures for NTM

The role of NTM in infectious disease processes is only starting to be recognized. This work documents that a proportion of patients with CRS could be infected with NTM and that sinus samples should be cultured for NTM. In addition, CRS patients should avoid sinus irrigation with tap water because tap water may contain NTM, and it may not be possible to remove it. Sterile saline should be used instead.

Pulsed-field gel electrophoresis (PFGE) of AseI digest patterns of patient and household isolates, New York, New York, USA, 2001–2011. A) Patient and household isolates. Lane 1, λ ladder; lane 2, patient no. 5 Mycobacterium avium isolate AG-P-1; lane 3, patient no. 5 household filter M. avium isolate AG-F-2-0-2; lane 4, patient no. 5 household filter M. avium isolate AG-F-2-I-1 (environmental isolates in lanes 3 and 4 are indistinguishable; patient isolate in lane 2 considered clonal with 2 environmental isolates [6 bands difference]); with digestion with XbaI, the 3 were considered closely related.); lane 5, patient no. 6 M. avium complex “X” cluster (MAC-X) isolate GG-P-1; lane 6, patient no. 6 household swab M. chimaera isolate GG-Sw-9–1 (despite overall similarity, isolates in lanes 5 and 6 belong to different species and differ by 10 bands and are therefore unrelated). B) Additional patient and isolate from the person’s household. Lane 1, patient no. 2 M. avium isolate BB-P-1; lane 2, patient no. 2 household water M. avium isolate BB-W-4–5; lane 3, λ ladder.
