They inhabit soil and water and are particularly resistant to disinfectants and high temperature. The environmental sources include aerosolized water and soil. Showers, water heaters, potted plants and compost are also probable sources. Few Indian studies have reported a high prevalence among non HIV infected individuals. The lack of laboratory facilities is the major challenge to determining exact…
