The rapidly growing organisms such as M. chelonae, M. fortuitum and M. abscessus are widespread in nature and in hospital environments. They are also highly resistant to antibiotics, antiseptics and disinfectants and hence are important nosocomial pathogens. These organisms are notorious for causing infections of soft tissues, tendons, bones and joints. Surgical procedures, accidental trauma or injections are also considered as risk factors for infections involving these organisms. M chelonae causes various clinical syndromes, including lung disease, local cutaneous disease, osteomyelitis, joint infections and ocular disease. With the exception of lung disease, these syndromes commonly develop after trauma. M. chelonae is a rare cause of isolated lymphadenitis. Endocarditic has also been documented. Disseminated skin and soft tissue lesions, occurs almost exclusively in the setting of immuno-suppression, especially AIDS. Esophageal disorders may place patients at increased risk for pulmonary disease due to rapidly growing mycobacteria.
