“…Our review showed that MSIs involving NTM have not been investigated to the same extent as compared to those caused by M. tuberculosis ( Table 2). Amongst the 121 mycobacterial studies identified, 26 (21.5%) examined NTM, of which 17 (14.0%) and eight (6.6%) found MSIs in humans and animals, respectively, whereas one report identified MSIs in both human (Arbeit et al, 1993;Slutsky et al, 1994;Von Reyn et al, 1995;Devallois and Rastogi, 1997;Picardeau et al, 1997;Wallace et al, 1998;Legrand et al, 2000a,b;Oliveira et al, 2000;Saad et al, 2000;Dvorska et al, 2002;Panunto et al, 2003;Ohkusu et al, 2004;De Sequeira et al, 2005;Fujita et al, 2014;García-Pedrazuela et al, 2015;Kimizuka et al, 2019) and animal (Dvorska et al, 2007;Shitaye et al, 2008;Furphy et al, 2012;Gerritsmann et al, 2014;Johansen et al, 2014;Gioffré et al, 2015;Podder et al, 2015;Davidson et al, 2016;Pfeiffer et al, 2017) populations simultaneously (Pate et al, 2008). Many early studies used pulsed field gel electrophoresis (PFGE) to identify MSIs in 14.3-100% of patients infected with MAC bacteria (Arbeit et al, 1993;Slutsky et al, 1994;Von Reyn et al, 1995;Wallace et al, 1998;Ohkusu et al, 2004).…”

“…Though the presence of IS1245-RFLP may be supplemented using additional methods, studies have shown it alone is capable of identifying 2.6-100% of NTM MSIs in samples from human subjects, some with HIV-AIDS (Supplementary Table 2) (Picardeau et al, 1997;Saad et al, 2000;Dvorska et al, 2002;Panunto et al, 2003;Pate et al, 2008). In addition, a study examined 41 samples from 14 AIDS patients using MaDRE-PCR, which found four cases with multiple banding patterns, though re-evaluation using IS1245-RFLP only confirmed two as M. avium MSIs (De Sequeira et al, 2005). Based on the reports mentioned above, the feasibility of using IS1245-RFLP as a screening method for detecting NTM MSIs warrants further evaluation.…”

Methods for Detecting Mycobacterial Mixed Strain Infections–A Systematic Review

et al. 2020

Mixed strain infection (MSI) refers to the concurrent infection of a susceptible host with multiple strains of a single pathogenic species. Known to occur in humans and animals, MSIs deserve special consideration when studying transmission dynamics, evolution, and treatment of mycobacterial diseases, notably tuberculosis in humans and paratuberculosis (or Johne's disease) in ruminants. Therefore, a systematic review was conducted to examine how MSIs are defined in the literature, how widespread the phenomenon is across the host species spectrum, and to document common methods used to detect such infections. Our search strategy identified 121 articles reporting MSIs in both humans and animals, the majority (78.5%) of which involved members of the Mycobacterium tuberculosis complex, while only a few (21.5%) examined non-tuberculous mycobacteria (NTM). In addition, MSIs exist across various host species, but most reports focused on humans due to the extensive amount of work done on tuberculosis. We reviewed the strain typing methods that allowed for MSI detection and found a few that were commonly employed but were associated with specific challenges. Our review notes the need for standardization, as some highly discriminatory methods are not adapted to distinguish between microevolution of one strain and concurrent infection with multiple strains. Further research is also warranted to examine the prevalence of NTM MSIs in both humans and animals. In addition, it is envisioned that the accurate identification and a better understanding of the distribution of MSIs in the future will lead to important information on the epidemiology and pathophysiology of mycobacterial diseases.

“…New techniques include diagnostic deoxyribonucleic acidribonucleic acid (DNA-RNA) and polymerase chain reaction (PCR) tests for specific mycobacterial genes (9,10,11,13,15,20,21,25,28,29). Polymorphism restriction analysis (PRA) is used for identifying mycobacterial species and subspecies (8,10,42,55). Another DNA cleavage technique involves pulsed-field gel electrophoresis which identifies subspecies within a group.…”

Avian mycobacteriosis is important for animal and human health; wild birds play an important role in mycobacterial species' ecology and movement. This review was aimed at reporting the role of birds in the spread of avian mycobacteriosis in human and animal populations at risk and thus a systematic review was made of PubMed, Science Direct, Scielo and Scirus databases. Mycobacteria are classified into the Mycobacterium tuberculosis complex and non-tuberculous mycobacteria; the Mycobacterium avium complex represents the most important part of the latter because it is primarily responsible for mycobacterial infection in wild birds and is a potential pathogen for mammals, especially for immunocompromised patients. The clinical signs in birds are variable as it is a chronic and debilitating disease, involving emaciated carcasses, white nodules in different organs and microscopically it presents granulomatosous multifocal inflammation. Diagnosis begins by suspicion based on clinical signs and finishes with microbiological confirmation. New diagnostic techniques include testing with DNA-RNA probes. No effective treatment is currently available and chemoprophylaxis on suspicion of infection is not recommended at the start; these factors increase the potential risk of mycobacteriosis becoming one of the most frequently documented zoonotic diseases which is difficult to treat in birds and humans. Recent concern regarding mycobacterial infection lies in the increased frequency of these opportunistic infections occurring in immunocompromised individuals and these infections' potential impact on bird conservation, this being increased by greater contact between humans and wild and captive birds.
