M. leprae are found in large numbers in sweat glands, sweat ducts, sebaceous glands, hair follicles and arrector pili muscles. Further in lepromatous leprosy the granulomas mainly surround the skin adnexa which atrophy due to pressure by the granuloma. However in tuberculoid leprosy the inflammatory cells infiltrate the adnexal tissues and destroy them. This study confirms that M. leprae are discharged and disseminated through sweat and sebaceous secretions and therefore infection through skin to skin contact can be one of the common modes of transmission of the disease.</p>  a0024-1024
