Nontuberculous mycobacteria (NTM) are potentially pathogenic agents commonly found in natural ecosystems, while food is considered to be another source of NTM for humans. We investigated a total of 92 tissue samples of freshwater fish and fish products: fish directly obtained from ponds (n=25), retail fresh (n=23) and frozen fish (n=23) and smoked fish products (n=21). Culture examination for the presence of mycobacteria was positive in 11 (11.9%) from all the examined samples. The 15 obtained isolates were identified as Mycobacterium fortuitum (n=5), M. immunogenum (n=2), M. phocaicum/ mucogenicum (n=1), M. neoaurum (n=2), M. peregrinum (n=2), M. porcinum (n=1) and M. senegalense/houstonense/conceptionense (n=2). NTM DNA was found in one (4.0%) sample of fresh fish from ponds and in 60.9% and 91.3% of retail fresh and frozen fish, respectively. None of the smoked fish products contained NTM DNA. The results of our study suggest that freshwater fish and fish products, especially retail frozen fish, might be a reservoir of NTM for humans, and proper handling and treatment before consumption of such products is recommended.

Mycobacteriosis is a progressive disease of a wide range of wild and captive, marine and freshwater fish species. Conventional detection of fish Mycobacteria is based on histopathology, culture, and biochemical characteristics. The present study analyzed the occurrence of Mycobacteria in clinically ill ornamental fish of different species, from different places of India. In first group, 60 fish were examined for presence of granulomatous inflammation and acid-fast bacteria. Thirty-eight (63.34 %) fish were positive for granulomatous inflammations. Presences of acid-fast bacteria were detected in 27 (45 %) fish having granulomatous inflammation and in two (3.33 %) fish without granulomatous inflammation. In total, AFB were found in 29 (48.34 %) of the 60 fish examined. In second group, 20 fish having granulomatous inflammation, 12 (60 %) samples were positive using Ziehl-Neelsen (Z-N) staining and 11 (55 %) of them were culture positive. Eight (40 %) samples were Z-N negative but two (10 %) of them were culture positive. In total, 13 (65 %) of the 20 examined fish were culture positive. On the basis of biochemical tests and 16S rRNA sequencing, 13 isolates were identified: five as Mycobacterium fortuitum, five as Mycobacterium gordonae, and three as Mycobacterium chelonae. In comparison of two decontamination methods, 2 % HCl treatment was better than 4 % NaOH treatment. Mycobacteria recovery from decontaminated samples was significantly high on Lowenstein-Jensen medium compared to Middlebrook 7H11 agar and Stonebrink (SB) media. The disease is transmissible from fish to fish and also from fish to human, so the significance of Mycobacteria in ornamental fish should not be overlooked.
