Abstract

THOMAS, Manuel; SAMUEL K, Abraham  and  KURIAN, Punnen. Rodentborne fungal pathogens in wetland agroecosystem. Braz. J. Microbiol. [online]. 2012, vol.43, n.1, pp. 247-252. ISSN 1517-8382.  http://dx.doi.org/10.1590/S1517-83822012000100028.

The past few decades have witnessed an overwhelming increase in the incidence of fungal infections, particularly in immunocompromised individuals. Consequently, zoonotic diseases, especially through rodents constitute a prominent group among the emerging diseases. Rodents are commensal to man and related health risks are common. Water rats (Rattus norvegicus) are typical to Vembanadu-Kol wetland agroecosystems, where they can act as a good carrier nexus for pathogens. The present study evaluates the carrier status of water rats with respect to fungal pathogens. A total of fifty two fungi covering eighteen families were isolated. Among the isolates, eight were dermaptophytes and Chrysosporium sp. (89.18%) was the frequent isolate. The source-wise analyses showed an increased isolation from ventral hair (67 isolates).  Water rats of Vembanadu-Kol wetland agroecosystem are potent carrier of dermaptophytes and other opportunistic fungi, and strong carrier paths are existing too.
