mycobacterial skin infection

However, in most countries, at least 70% of all cases are diagnosed in the stage with deep ulceration. Geography-based environmental exposures influence the epidemiology of cutaneous mycobacterial infections. 7) (24, 42, 117). He is currently an Associate Professor of Clinical Medicine in the Division of Infectious Diseases at Stony Brook University and serves as the Fellowship Program Director. Epub 2015 May 8. Earlier lesions presenting as papules or nodules are usually painless but when these lesions evolve into ulcerations or abscesses, patients may experience significant pain. The differential diagnosis of lupus vulgaris is with conditions such as discoid lupus, sarcoidosis, Spitz nevus, chromoblastomycosis, tuberculoid leprosy, and leishmaniasis. Innate immune responses by macrophages in human tissues are responsible for initiating nerve damage in leprosy by interaction with phenolic glycolipid 1 (PGL-1) with myelinating glia (88, 89). Skin biopsies of cutaneous lesions to identify acid-fast staining bacilli and cultures represent the cornerstone of diagnosis. Another one causes leprosy. Genomic events such as genome reduction, critical gene acquisition, gene transfer, mutations, and recombination permitted environmental mycobacteria to evolve into host-associated pathogens (2, 5, 9, 11, 14–16, 19). Cutaneous forms of tuberculosis are a rare clinical manifestation of M. tuberculosis or M. bovis infection, comprising approximately only 1 to 2% of all TB cases (47, 64–67). Mycobacterium ulcerans produces a mycolactone toxin that leads to subcutaneous tissue destruction and immunosuppression, resulting in deep ulcerations that often produce substantial disfigurement and disability. Cutaneous infection may present as nodules, pustules, verrucous lesions, erythematous plaques, ulcers, and abscesses (Fig. Thank you for sharing this Clinical Microbiology Reviews article. Similarly, phylogeographic studies of the tuberculous bacilli have shown that the dominant clone of smooth tubercle bacilli (Mycobacterium canettii) emerged in eastern Africa and later diversified into the Mycobacterium tuberculosis complex during the worldwide spread of TB by waves of human migration (5, 11). Characteristic sporotrichoid nodular lymphangitic spread of Mycobacterium marinum. Phylogeographic studies uncovered the origin of leprosy in eastern Africa and its spread through the Silk Road or the transatlantic slave migration trade routes (7, 8, 10, 12). Some of the features include the presence of a lipid-rich hydrophobic outer membrane, which is a major determinant of surface adherence, biofilm formation, aerosolization, and antibiotic/disinfectant resistance. Molecular detection methods and phenolic glycolipid 1 (PGL-1) serological data in combination with spatial epidemiology increase detection of leprosy cases (98). 9) (120). Human Societies and the Origin and Spread of Major Mycobacterial PathogensMycobacteria are aerobic rod-shaped bacteria that do not form spores and that are lipid rich with long-chain mycolic acids in their cell walls, which are largely responsible for their acid fastness (1). A similar mechanism of transmission maybe responsible for some cases of leprosy (33). In some of the British Isles, red squirrels may develop leprosy-like lesions due to either M. leprae or Mycobacterium lepromatosis (53). Comparison of epidemiological and clinical features of the four categories of cutaneous mycobacterial infections: cutaneous tuberculosis, leprosy, Buruli ulcer, and disease caused by nontuberculous mycobacteria. Mycobacterial species are present in the environment in water and soil niches that are shared with humans (19, 21, 22).In the human host, mycobacterial infections may affect many anatomical sites, but since they enter through the skin and mucosal barriers, they lead mostly to pulmonary or cutaneous infections (25 – 28).The pathogenesis of cutaneous mycobacterial infections … Chau, C. L. F., et al. 2010 Oct;23(5):445-55. doi: 10.1097/QCO.0b013e32833c2209. This clinical form affects women predominantly and manifests as smoldering nodules and annular plaques, or it may present with hypertrophic or vegetative lesions. Disruption of skin and soft tissues frequently constitutes the portal of entry of NTM from environmental niches (soil, natural water systems, engineered water networks, etc.) The most common clinical presentations of mycobacterial infections include pulmonary, cutaneous and disseminated forms in immunocompromised hosts. The clinical manifestations of cutaneous involvement include cellulitis, papular lesions, nodules with purple discoloration, abscesses, draining sinuses, subcutaneous nodules (pseudoerythema nodosum), and ulcerations (117). Among the rapidly growing mycobacteria, it is the most common cause of lung disease (117). He completed an internship and residency in internal medicine at the University of Texas Health Science Center, followed by a fellowship in infectious diseases at Washington University.

MAC is composed of several different slowly growing mycobacterial species, including M. avium, M. intracellulare, Mycobacterium indicus pranii, Mycobacterium chimera, Mycobacterium arosiense, and many others. (Slightly dated but comprehensive and provides a table of cutaneous and extracutaneous manifestations of infection of each organism, as well as a table detailing the growth characteristics of each of the mycobacterial … Visceral tuberculosis (pulmonary or extrapulmonary) is rarely associated with concomitant cutaneous involvement (68). Identification of mycobacterial DNA in cutaneous lesions of sarcoidosis. Curr Opin Infect Dis. In the human host, mycobacterial infections may affect many anatomical sites, but since they enter through the skin and mucosal barriers, they lead mostly to pulmonary or cutaneous infections (25–28). Skin and soft tissue infections are the most common pre-sentation for the rapid-growing speciesMycobacterium fortuitum, M. abscessus,andM. Mycobacterial infections of the skin and subcutaneous tissue are associated with important stigma, deformity, and disability. Clinically, cutaneous mycobacterial infections present with widely different clinical presentations, including cellulitis, nonhealing ulcers, subacute or chronic nodular lesions, abscesses, superficial lymphadenitis, verrucous lesions, and other types of findings. Eduardo Liceaga.” He is also a Researcher of the Health Systems, Health Secretary, Mexican Government, and Senior Researcher of the National System of Researchers (CONACYT). Preclinical Models of Nontuberculous Mycobacteria Infection for Early Drug Discovery and Vaccine Research. WHO identifies approximately 3,000 to 5,000 cases annually, affecting predominantly children less than 15 years of age (20, 31, 32, 109). The clinical spectrum of disease associated with mycobacterial pathogens depends on the route of exposure and host susceptibility factors (25–27). Mycobacterium marinum, a close relative of M. ulcerans, is an important cause of cutaneous sporotrichoid nodular lymphangitic lesions. In fact, there is less than 1% nucleotide variation among all mycolactone-producing mycobacteria (113). Mycobacterium marseillense is a member of the M. avium complex that has caused infections with lymphatic or pulmonary involvement sporadically in humans (2–4).We report M. marseillense infection involving facial skin … He is an Associate Researcher, Colciencias and winner of the Wiliam Jarvis 2014 Award, Best International Research, awarded by SHEA. Modes of acquisition, history of previous sensitization to Mycobacterium tuberculosis, and clinical features of the cutaneous presentations of tuberculosis.

Since M. leprae is not cultivable, the bacteriostatic and bactericidal effects of antimycobacterial drugs against M. leprae have been assessed in laboratory studies (47). Tuberculosis verrucosa cutis of the hand, manifesting as verrucous plaques caused by direct inoculation of the tuberculous bacilli into the skin of an individual previously sensitized to this pathogen. He is a member of the Committee on Tropical Medicine, Zoonoses and Travel Medicine of ACIN. These lesions eventually lead to significant scarring (47, 69). Relapse or reinfection is considered a rare clinical phenomenon (47, 78, 86, 87). Additionally, histopathological evaluation of skin biopsy specimens may be useful in identifying leprosy, Buruli ulcer, and cutaneous tuberculosis. Mycobacterium kansasii leading to a sporotrichoid nodular lymphangitis of the right arm. His current research activities include the epidemiology and clinical spectrum of leprosy and other cutaneous mycobacterial diseases. Some identified risk factors for developing this clinical variant include minor trauma, tattoos, piercing, and surgical procedures with unsterilized equipment (47, 71). Tuberculosis cutis orificialis occurs among severely immunocompromised middle-aged and older adults with advanced pulmonary, gastrointestinal, or genitourinary tuberculosis (47). Disseminated NTM infections affect severely immunocompromised human hosts, including those with primary immunodeficiencies, such as genetic or acquired defects of the IFN-γ–interleukin-12 (IL-12) pathway (e.g., GATA2 deficiency or anti-IFN-γ autoantibodies), or acquired immunodeficiencies, such as HIV infection/AIDS, transplant-associated immunosuppression, and treatment with biological agents such as anti-tumor necrosis factor alpha (anti-TNF-α) receptor blockers (26, 27, 116). Since the early 1980s, multidrug therapy (MDT) has been universally instituted through active case finding in highly affected communities. 4) (72, 74, 78). He is part of the Executive Board of the Latin American Society for Travel Medicine (SLAMVI). Clipboard, Search History, and several other advanced features are temporarily unavailable. Currently, most cases of Buruli ulcer occur in parts of western and central Africa, but cases occur in at least 33 countries, mostly in South America and Western Pacific regions (110). In children, this infection usually presents as cervical lymphadenitis (35, 36). This form is also known as tuberculosis colliquative cutis. of woman with Mycobacterium marseillense skin infection, China, 2018, and genomic analysis of isolate. He received his M.P.H. He has 172 publications in peer-reviewed journals. Infection caused by Mycobacterium fortuitum associated with mesotherapy. BU is considered a neglected tropical disease (NTD) because most cases occur among impoverished populations, often causing an important disability burden (2, 15, 31, 32, 109). Leprosy reactions, due to their potential inflammatory compromise of the nerve fibers, lead to sensory and motor loss (85, 90–92). It is recommended that rapidly growing mycobacteria be tested against selected antibacterial drugs of different classes (1, 42). Infection caused by Mycobacterium fortuitum associated with mesotherapy. The modes of transmission of the different mycobacterial species involved in cutaneous disease include zoonotic transmission (e.g., foodborne transmission of Mycobacterium bovis by ingestion of unpasteurized dairy products) (16, 23), person-to-person transmission (e.g., of leprosy) (29, 30), vector-borne transmission (possibly for Mycobacterium ulcerans) (3, 31–33), and acquisition of infection from environmental exposures (e.g., freshwater or salt water injuries leading to Mycobacterium marinum, M. ulcerans, or Mycobacterium haemophilum infection) (24, 33–38) (Table 1). The correct identification of the specific RGM infecting the skin will enhance … Nontuberculous mycobacteria (NTM), i.e., those mycobacterial species that do not cause tuberculosis or leprosy, are frequently present in municipal water systems, residing mostly in the pipeline biofilms (21, 22, 38, 39). In many individuals, pathogenic mycobacterial species may breach our first-line barrier defenses of the innate immune system and modulate the activation of phagocytes to cause disease of the respiratory tract or the skin and soft tissues, sometimes resulting in disseminated infection. Similarly, acute military tuberculosis represents primary infection in individuals with advanced immunosuppression, including those with HIV infection/AIDS (71). Traditionally, immunocompromised patients suffer from NTM infections, especially with respiratory involvement or disseminated diseases due to MAC (Mycobacterium avium complex).Here we report a rare case of Mycobacterium intracellulare infection involving skin … Geography-based environmental exposures influence the epidemiology of cutaneous mycobacterial infections. M. ulcerans is a slowly growing environmental mycobacterium causing infection that is considered to have an incubation period of 5 to 8 weeks, but this may be as long as six months in areas of endemicity (31, 109). Cosmetic procedures such as mesotherapy (multiple injections of pharmaceutical products, plant extracts, homeopathic substances, vitamins, or other compounds into subcutaneous fat) have been involved in the transmission of rapidly growing mycobacteria (1, 24, 42, 117). Nontuberculous mycobacteria (NTM) infections still represent a large group of insidious diseases hard to deal with. Skin and soft tissue (typically following surgery, trauma, injection of medications or other substances) Device associated infections (e.g., central line associated bloodstream infection, exit site infections, pacemaker pocket site infections… The most notable mycobacterial infections are those that are caused by Mycobacterium tuberculosis complex and Mycobacterium leprae. Enferm Infecc Microbiol Clin. M. kansasii has been identified only in municipal water systems (21, 22, 42). haemophilum, are also more frequently associated with skin … Efficacy and Mechanisms of Flavonoids against the Emerging Opportunistic Nontuberculous Mycobacteria. Rapid diagnostic tests to detect mycolactone are currently under evaluation for use as point-of-care tests in areas of high endemicity (109). Dermatologic surgery 28.8 (2002): 768-771. That is a blessing and a curse. This article reviews the dermatologic manifestations of Mycobacterium avium-intracellulare (MAI, or MAC) infection.. MAI is an opportunistic pathogen that usually causes disease in the weakened immune system. ASM journals are the most prominent publications in the field, delivering up-to-date and authoritative coverage of both basic and clinical microbiology. What is an atypical mycobacterial infection?. Would you like email updates of new search results? Tuberculosis is a mycobacterial infection that most frequently occurs due to infection with Mycobacterium tuberculosis, an acid-fast bacillus. Prior to joining the Division of Infectious Diseases at the University of Colorado as an Associate Professor of Medicine in 2017, Dr. Franco-Paredes was an Associate Professor of Medicine and Global Health at Emory University (2004 to 2011) and a Staff Physician in Infectious Diseases at Phoebe Memorial Hospital in Albany, GA (2011 to 2017).
