“…In crustaceans, Davidovich et al [ 5 ], reported on a mycobacterial infection in redclaw crayfish Cherax quadricarinatus caused by M. gordonae . Histopathological examination indicated that the immune system’s reaction to the pathogenic-microorganism consists of melanised haemocytic aggregations (fixed phagocytes) with perivascular cuffing of the haemal spaces in the hepatopancreas and encapsulation reactions.…”

“…Recently, Davidovich et al [ 5 ], described a case of co-infection in redclaw crayfish C. quadricarinatus in a small-scale recirculating aquaculture system hatchery in Israel ( Table 2 ). Histopathological examination and bacterial identification confirmed an opportunistic infection caused by M. gordonae .…”

“…Aquatic invertebrate mycobacterioses range from an acute, fulminant disease eventually related to MME [ 4 ], to the more frequently observed chronic forms characterized by low bacterial load and chronic inflammation in the host [ 5 ]. External clinical signs of disease, if present, are non-specific; they may include multiple raised, black to brown lesions of the cuticle or internal organs [ 13 , 14 ] or visible orange nodules in the adductor muscle as in the case of affected Atlantic sea scallop P. magellanicus [ 15 ].…”

“…Mycobacteriosis is a chronic progressive disease caused by various acid-fast bacilli (AFB) affecting numerous wild and cultured aquatic invertebrate species worldwide [ 4 , 5 ]. These microorganisms are saprophytes that reside in both soil and fresh and salt water, where they can exist for prolonged periods; they are gradually being recognized as emerging pathogens causing opportunistic infections in humans, farmed species and wildlife [ 6 ].…”

“…In some cases, mycobacterial infections in aquatic invertebrates co-occur with other pathogens. For example, Davidovich et al [ 5 ], described an infection caused by two pathogenic-microorganisms in redclaw crayfish Cherax quadricarinatus (von Martens, 1868): Mycobacterium gordonae and Cherax quadricarinatus bacilliform virus (CqBV). Pen shells Pinna nobilis (Linnaeus, 1758) collected in Italy and Spain presented with co-occurrence of Mycobacterium sp., the parasite Haplosporidium pinnae and other pathogens [ 16 ].…”

Mycobacteriosis in Aquatic Invertebrates: A Review of Its Emergence

Mycobacteriosis is a chronic bacterial disease reported in aquatic and terrestrial animals, including humans. The disease affects a wide range of cultured and wild organisms worldwide. Mycobacteriosis is well-known in aquatic vertebrates (e.g., finfish, marine mammals), while in the last few years, reports of its presence in aquatic invertebrates have been on the rise, for both freshwater and marine species. The number of cases is likely to increase as a result of increased awareness, surveillance and availability of diagnostic methods. Domestication of wild aquatic species and the intensification of modern aquaculture are also leading to an increase in the number of reported cases. Moreover, climate changes are affecting fresh and marine aquatic ecosystems. The increasing reports of mycobacteriosis in aquatic invertebrates may also be influenced by global climate warming, which could contribute to the microbes’ development and survival rates, pathogen transmission and host susceptibility. Several species of the genus Mycobacterium have been diagnosed in aquatic invertebrates; a few of them are significant due to their wide host spectrum, economic impact in aquaculture, and zoonotic potential. The impact of mycobacteriosis in aquatic invertebrates is probably underestimated, and there is currently no effective treatment other than facility disinfection. In this review, we provide an overview of the diversity of mycobacterial infections reported in molluscs, crustaceans, cnidarians, echinoderms and sponges. We highlight important issues relating to its pathological manifestation, diagnosis and zoonotic considerations.
