Résumé
Isolated fungal soft-tissue infections are uncommon but may cause severe morbidity or mortality, especially among immunosuppressed patients. In this study, a total of 56 soft-tissue specimens from patients with clinical suspicion of fungal infection collected at a tertiary care centre in Chennai during the period December 2005 to May 2007 were evaluated. Among the culture positives, majority were from diabetic patients. Among the 34 culture positives, the isolates consisted of Candida 12, Fusarium 4, Rhizopus 1 and Aspergillus 3 one each of Absidia corymbifera and Apophysomyces elegans. Treatment of fungal soft-tissue infection requires a team approach of surgeons, pathologists and microbiologists.
Résumé
An indirect immunofluorescent (FLA-ABS) test has been developed to detect M. leprae specific antibodies in the active and subclinical cases of leprosy. An antigenically related mycobacterium, M. habana, was used as an antigen to detect M. leprae specific antibodies in the sera samples of leprosy patients. A comparison was made with M. leprae antigen using same set of sera samples. M. habana is capable of detecting anti-M. leprae antibodies in the serum samples of leprosy patients, previously absorbed with various mycobacterial antigens, cardiolipin and lecithin, almost to the same percentage as M. leprae. Possible use of M. habana antigen as an alternative to M. leprae, in the serodiagnosis of leprosy, has been discussed.
