“…Aeromonosis is one the most destructive infectious disease in farmed fish, causing great problems in relation to production (Bentzon‐Tilia et al., 2016; Dias et al., 2016; Figueras‐Salvat & Ashbolt, 2019; Wamala et al., 2018), as occurred with A. gigas in the present study. However, so far, only a few reports have indicated that A. jandaei is pathogenic to farmed fish.…”

“…Globally, bacterial infections represent a great threat to fish production due to the high economic losses that they cause to the fish‐farming industry (Assefa & Abunna, 2018; Bentzon‐Tilia et al., 2016; Figueras‐Salvat & Ashbolt, 2019; Wamala et al., 2018). This threat is also seen in relation to farmed fish in Brazil, such as A. gigas (Proietti‐Junior et al., 2017; Tavares‐Dias & Martins, 2017; Zaniboni‐Filho et al., 2018).…”

“…Several bacterial species have been reported to cause diseases in freshwater farmed fish around the world. The pathogens of particular importance include those of the genus Aeromonas (Chandrarathna et al., 2018; Fig ueras‐Salvat & Ashbolt, 2019; Fowoyo & Achimugu, 2019; Wamala et al., 2018). Aeromonas comprises a group of ubiquitous oxidase‐positive Gram‐negative bacilli that are considered to be autochthonous in aquatic environments (Bentzon‐Tilia et al., 2016; Figueras‐Salvat & Ashbolt, 2019; Fowoyo & Achimugu, 2019).…”

Although infections caused by more than one species of Aeromonas are frequent in fish farming around the world, studies on co‐infections caused by such bacteria species have been little (Chandrarathna et al., 2018; Mosser et al., 2015).…”

In fish, bacteriosis has been widely linked with Aeromonas species, but co‐infection by these bacteria has been little addressed. The aims of this study were to report on an outbreak of disease in pirarucu Arapaima gigas caused by Aeromonas and to investigate experimental co‐infection and characterize resistance profile, virulence factors and phenotypic and molecular differentiation. Fish samples with clinical signs of bacteriosis were collected and used to study experimental co‐infection. The bacterial isolates were characterized phenotypically as Aeromonas hydrophila and Aeromonas jandaei. Virulence genes aerA, gcat, lip, dnase and hlyA were detected using the polymerase chain reaction, while the alt, act and ser genes were not found. Resistance to imipenem and ceftriaxone was observed; however, all isolates were susceptible to most of the antibiotics assayed. Phenotypic tests to determine the presence of metallo‐β‐lactamases showed positivity only for A. jandaei strains. Assays for the resistance genes kpc, ndm, imp, oxa‐48 and vim showed negative results. The co‐infection and pathogenicity of A. hydrophila in association with A. jandaei in A. gigas, established in accordance with Koch's postulate, provided experimental support for the existence of synergism between these bacteria. This has several implications relating to occurrences of this co‐infection and determinants of virulence.

“…In fact, Helicobacter pylori, as previously stated for Legionella spp., can be internalized and viable inside Acanthamoeba castellanii (Moreno-Mesonero et al, 2016), which could also be detected in all samples tested. The presence of Aeromonas has been related to stagnant water with low/no levels of chlorine and presence of organic matter (Figueras and Ashbolt, 2019). Our persistent detection of Helicobacter pylori in the untreated irrigation water sources has been related to the exposure to sewage (Bellack et al, 2006).…”

Purpose of Review Mounting evidence indicates that habitats such as wastewater and environmental waters are pathways for the spread of antibiotic-resistant bacteria (ARB) and mobile antibiotic resistance genes (ARGs). We identified antibiotic-resistant members of the genera Acinetobacter, Aeromonas, and Pseudomonas as key opportunistic pathogens that grow or persist in built (e.g., wastewater) or natural aquatic environments. Effective methods for monitoring these ARB in the environment are needed to understand their influence on dissemination of ARB and ARGs, but standard methods have not been developed. This systematic review considers peer-reviewed papers where the ARB above were cultured from wastewater or surface water, focusing on the accuracy of current methodologies. Recent Findings Recent studies suggest that many clinically important ARGs were originally acquired from environmental microorganisms. Acinetobacter, Aeromonas, and Pseudomonas species are of interest because their ability to persist and grow in the environment provides opportunities to engage in horizontal gene transfer with other environmental bacteria. Pathogenic strains of these organisms resistant to multiple, clinically relevant drug classes have been identified as an urgent threat. However, culture methods for these bacteria were generally developed for clinical samples and are not well-vetted for environmental samples. Summary The search criteria yielded 60 peer-reviewed articles over the past 20 years, which reported a wide variety of methods for isolation, confirmation, and antibiotic resistance assays. Based on a systematic comparison of the reported methods, we suggest a path forward for standardizing methodologies for monitoring antibiotic resistant strains of these bacteria in water environments.
