ABSTRACT
This study traces the earliest cases of blastomycosis reported from India. Four authentic cases of blastomycosis from India including one each from Arunachal Pradesh, Himachal Pradesh, Kerala, and one each from Bangladesh and Nepal, and five misdiagnosed cases have been reported in India after 2013. The clinical and diagnostic features of all cases are reviewed. The authentic cases from India originate from widespread locations in the country. The incidence of blastomycosis in dogs is known to be eight to ten times higher than that in humans. There is only one case of canine blastomycosis from India manifesting as a fatal pulmonary infection in a Mongrel dog. It is suggested additional canine cases should be looked for in different parts of India to facilitate the detection of endemic foci of B. dermatitidis for human and animal infections in the country. Mycological investigation of cases of pulmonary tuberculosis negative for culture and AFBs mear, and not responding to anti-tubercular therapy may reveal some cases of blastomycosis. A recently developed real-time PCR for identification of B. dermatitidis in culture and tissue may facilitate correct diagnosis of blastomycosis in suspected cases. Antigen testing in urine or serum is also recommended for diagnosing clinical infection and monitoring antifungal therapy in blastomycosis.
