“…The presence of P. damselae in almost all Apogonidae libraries implies a longstanding relationship between Photobacterium and cardinal shes on coral reefs, suggesting that this genus might have originated and diversi ed in the reef environment. Overall, these data show that cardinal shes serve as natural hosts for P. damselae and should be monitored closely, particularly if interacting with farmed populations that are often severely affected by opportunistic infections of P. damselae [42].…”

Background Reef fishes account for one-third of all extant marine fishes and exhibit enormous biodiversity within a highly interactive ecosystem. Despite this, relatively little is known about the diversity and evolution of microbial species (bacteria, viruses, and eukaryotes) associated with reef fish, even though this may provide valuable insights into the factors that shape microbial communities within vertebrate hosts as well as the extent and pattern of cross-species transmission. Results Through metatranscriptomic sequencing we characterised the viruses, bacteria, and single-celled eukaryotes from 126 reef fish species inhabiting Lizard Island and Orpheus Island on the Great Barrier Reef, Australia. We assessed whether microbial communities differed between islands that are separated by approximately 450 kilometres, and to what extent viruses were able to emerge in new hosts. Notably, despite strong ecological interactions in the reef environment, and the presence of the same families and subfamilies of viruses and bacteria on both islands, there was minimal evidence for the cross-species transmission of individual microorganisms among fish species. An exception was the high prevalence of the opportunistic bacterial pathogen Photobacterium damselae among apparently healthy cardinalfishes from both islands, indicating that these fish species are natural reservoirs within the reef system. Conclusions These data suggest that reef fishes have microbial-host associations that arose prior to the formation of the Great Barrier Reef, leading to strong host barriers to cross-species microbial transmission and hence infectious disease emergence, even within a highly interactive and species-rich environment.

“…From the identified Vibrionaceae from diseased and non‐diseased Asian sea bass, distribution among Vibrionaceae isolates in the non‐diseased fish was dominated by P. damselae followed by V. vulnificus and V. navarrensis. P. damselae is known as an emerging pathogen because of its wide geographic distribution and its negative impact on aquaculture organisms (Gouife et al, 2022). Non‐diseased fish (apparently healthy) can be infected by P. damselae without clinical signs.…”

This study describes the etiological agent of Vibriosis along with its distribution and antimicrobial resistance profiles among farmed Asian sea bass (Lates calcarifer) in Thailand. The study isolated 283 Vibrionaceae from 15 Asian sea bass farms located around the provinces of the Andaman Sea and Gulf of Thailand coasts to uncover the distribution and antimicrobial resistance profiles. Bacterial identification based on a combination of the biochemical characteristics, Matrix‐assisted laser desorption/ionization‐time of flight (MALDI‐TOF) mass spectrometry (MS) analysis, and the species‐specific PCR demonstrated the predominant Vibrionaceae were Vibrio harveyi (n = 56), Photobacterium damselae (n = 35), and V. vulnificus (n = 31), respectively. According to a laboratory challenge experiment, among the six isolates, only V. harveyi was found to cause clinical signs of muscle necrosis and scale loss in Asian sea bass. Antibiotics resistance test results exhibited high resistance to antibiotics such as metronidazole (100%), streptomycin (97%), clindamycin (96%), colistin sulphate (70%) and amoxicillin (59%). Remarkably, 100% of Vibrionaceae isolates are susceptible to florfenicol. The 28 of 29 resistance profiles were multidrug resistances (MDR), with V. vulnificus having the highest MAR value (0.66). The findings of this study advise that a surveillance program, as well as preventive and control measures, be developed for Vibrionaceae to reduce production loss, pathogen proliferation, and antibiotic abuse, whereas AMR data indicate substantial health problems for aquatic animals and humans.
