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.
过去几十年见证了真菌感染发病率的剧增，尤其是在免疫功能低下的个体中。因此，人畜共患病，特别是通过啮齿动物成为新兴疾病中的一个突出群体。啮齿动物与人类共生，相关健康风险很常见。水鼠（Rattus norvegicus）是 Vembanadu-Kol 湿地农业生态系统中的典型物种，它们可以作为病原体的良好载体枢纽。本研究评估了水鼠携带真菌病原体的情况。共分离出涵盖 18 个科的 52 种真菌。在分离出的真菌中，有 8 种为表皮真菌，而 Chrysosporium sp.（89.18%）是最常见的分离物。来源分析显示，从腹毛中分离出的真菌数量增加（67 个分离物）。Vembanadu-Kol 湿地农业生态系统中的水鼠是表皮真菌和其他机会性真菌的有力携带者，而且存在很强的携带途径。
