“…In ornamental fish, screening of fish from 27 species from four different pet shop in Poland revealed that M. marinum could only be isolated from dwarf gouramis (Trichogaster lalius) tested all T. lalius were affected and these fish displayed clinical signs consistent with the infection. On the other hand, members of the other fish species sampled carried other species of Mycobacteriaceae [57]. Similarly, a high prevalence (46.8%) of Mycobacterium sp.…”

Renibacterium salmoninarum and Mycobacterium spp.: two bacterial pathogens present at low levels in wild brown trout (Salmo trutta fario) populations in Austrian rivers

Background: Renibacterium salmoninarum and Mycobacterium sp. are important bacterial pathogens of fish. R. salmoninarum is the causative agent of bacterial kidney disease, a Gram-positive bacterium mostly known for causing chronic infections in salmonid fish, while multiple species belonging to the Mycobacterium genus have been associated with mycobacteriosis in fish as well as in human. The objective of this study was to determine the prevalence of these two bacterial pathogens in populations of wild brown trout (Salmo trutta fario) in four rivers (Kamp, Wulka, Traun and Ybbs) in Austria. Results: A total of 457 kidney samples were examined for both bacterial agents using nested and conventional PCR as well as bacterial cultivation on KDM-2, histological examination and immunohistochemistry. Molecular evidence showed an estimated prevalence level of 0.94% for R. salmoninarum in 2017 while the bacterium could not be detected in 2018 and histology showed signs consistent with a low-level chronic inflammation in the kidney of infected fish. Similarly, no fish were found positive for Mycobacterium in 2017 but in 2018, the prevalence was found to be 37.03% in the Kamp river (4.08% across all rivers). The sequencing data confirmed that these fish carried Mycobacterium sp. although the precise species of Mycobacterium could not be ascertained. Conclusions: This survey constitutes the first insight into the prevalence rate of R. salmoninarum and Mycobacterium sp. in wild brown trout (Salmo trutta fario) populations in Austria. Both of these pathogens were only detected in the summer months (June and July), which might suggest that the stress linked to increased water temperature could act as stressor factor and contribute to the outbreak of these diseases. The age of the fish might also play a role, especially in the case of Mycobacterium sp. as all the infected fish were in their first summer (June).

“…At histopathology, the main finding was instead represented by a visceral granulomatosis. This is a well‐known condition in fish pathology as an aspecific tissue response to numerous aetiologic agents, of which M. marinum , M. chelonae and M. fortuitum are most recognized and described in the literature (Gauthier & Rhodes, ; Puk et al, ). In this study, granulomas were detected in all of the batches analysed, including in asymptomatic fish collected immediately following their arrival.…”

Doctor fish (Garra rufa, Heckel, 1843) are increasingly used for cosmetic treatment raising particular concerns regarding the potential transmission of infections to clients. Investigations of microbial causes undertaken in two outbreaks of mortality among G. rufa used for cosmetic treatment revealed the presence of multiple bacteria, including both fish and human pathogens such as Aeromonas veronii, A. hydrophila, Vibrio cholerae, Shewanella putrefaciens, Mycobacterium marinum and M. goodii. This range of bacteria indicates an intense microbial proliferation involving multiple pathogens, most likely induced by the poor health condition of the fish. Most of the detected pathogens are well‐known agents of zoonosis. Indeed, M. goodii is an emerging nosocomial human pathogen that has never been detected in fish to date, nor in other animals. This first detection of M. goodii associated with fish infection points out a new zoonotic potential for this pathogen. These findings point out that handling, poor environmental conditions and the presence of fish pathogens, that can compromise the immune system of fish, can result in a mixed microbial proliferation and increase the spread of waterborne bacteria, including zoonosis agents. Accordingly, the microbiological surveillance of fish used for cosmetic treatment is extremely important, particularly in association with mortality outbreaks.

Aquarium ornamental pet fish constitute a major segment in the pet industry, with the United States, Europe, and Japan dominating the market. There are approximately 1,500 marine fish species and over 4,500 freshwater fish species commercialized as aquarium ornamental pet fish. Fish are the fourth most common pet present in Brazilian homes. In Brazil, aquarium ornamental pet fish can be marketed and distributed from different parts of the Brazilian territory and the world. Commercialization and circulation of living animals without the use of adequate prophylactic management procedures enables dissemination of a number of agents responsible for infectious diseases. Aquarium pet fish can also carry pathogenic agents, of bacterial, viral, fungal, or parasitic etiology, that may have a zoonotic feature endangering the persons handling the animals. This review presents the main pathogenic infectious agents of bacterial, viral, and fungal etiology that affect aquarium pet fish, as well as the prevention and control measures to ensure sanitary excellence in this segment.Peixes ornamentais de aquário representam um grande segmento no mercado de animais de estimação, no qual Estados Unidos, Europa e Japão dominam. São aproximadamente 1.500 espécies de peixes marinhos e em torno de 4.500 de espécies de água doce comercializados com fins ornamentais. O peixe é a quarta espécie mais comum nos domicílios brasileiros. Peixes ornamentais de aquário são comercializados e distribuídos em diferentes partes do território nacional e do mundo. O comércio e circulação de animais vivos sem o uso de procedimentos de manejo profilático adequados possibilita a disseminação de inúmeros agentes patogênicos. Peixes ornamentais de aquário carreiam consigo agentes patogênicos de etiologia bacteriana, viral, fúngica e parasitária, sendo alguns de caráter zoonótico colocando em risco pessoas que os manipulam. O objetivo desta revisão é apresentar os principais agentes infeciosos patogênicos -de natureza bacteriana, viral e fúngica -que acometem peixes ornamentais de aquário, bem como os métodos de prevenção e controle que permitam excelência no segmento.
