“…As shown in Figures 1 and 2, the PACs in the water and sediment of the six ponds typically ranged from 10 1 to 10 3 c.f.u./ml or c.f.u./g. These results corroborate with the previous data generated by Zdanowicz, Mudryk, and Perliński (2020) wherein the Aeromonas load in water of carp ponds ranged from 1.93 to 2.96 × 10 2 c.f.u./ml. In another study conducted by Jha, Barat and Nayak (2008), the quantities of Aeromonas spp.…”

Aeromonas load and species composition in the rearing water, sediment, gills and intestines of healthy tilapia Oreochromis niloticus collected every 2 weeks from Days 30 to 120 after stocking in six earthen ponds in the Philippines were determined. Presumptive Aeromonas counts (PACs) in the water and sediment ranged from 10 1-10 3 c.f.u./ml and 10 1-10 3 c.f.u./g while in the gills and intestines, PACs ranged from 10 4-10 7 c.f.u./g and 10 2-10 5 c.f.u./g, respectively. Presumptive Aeromonas counts in the water, sediment, and gills of tilapia varied among days of culture while in the intestines of tilapia, PACs markedly dropped by approximately 2 logs at Day 75 and either remained in the same level or decreased by another 1 log at Day 120 of growout culture. Aeromonas hydrophila predominantly constituted 94% of all presumptive Aeromonas spp. examined (n = 343), followed by A. sobria (4%) and A. salmonicida (2%). Taken together, current data provide some putative threshold levels of tilapia reared in earthen ponds to Aeromonas spp. The dominance of A. hydrophila together with negligible population of A. salmonicida and A. sobria indicate that Aeromonas are common commensal bacteria in tilapia and their environment which under conditions of stress could instigate disease epizootics.

“…Heavy rate of tetracycline‐resistant A. veronii was recovered from other species like catfish by Nawaz, Sung, Khan, Khan, and Steele (2006). Abundance of AMR in Aeromonas from three different carp ponds was compared and had shown their significant resistance towards beta‐lactams (Zdanowicz, Mudryk, & Perlinski, 2020).…”

Plasmid‐mediated antimicrobial resistance in motile aeromonads from diseased Nile tilapia ( Oreochromis niloticus )

et al. 2020

Aquaculture sector is in continuous progress throughout the world to meet the global fish food demand. In the earlier period onwards, tilapia cultivation gained more attention globally, next to carps, and more than 100 countries have selected tilapia as the candidate fish for aquaculture (Raj et al., 2019). Among them, Nile tilapia, Oreochromis niloticus, plays a major role in global production of tilapia by holding sixth position (Reantaso, 2017). Nile tilapia is one of the major fish species, which are more prone to aeromonad infections (Baumgartner, Ford, & Hanson, 2017). Disease outbreak due to aeromonads is frequent in farmed fish worldwide, and hence, the magnitude of infections and the characteristics of aetiological agents need to be analysed in detail (Mzula, Wambura, Mdegela, & Shirima, 2019). A wide range of diseases were reported in cultured fish due to different species of Aeromonas; mainly, A. hydrophila, A. veronii and A. caviae (Lewbart, 2001). One of the most important pathogens affecting cyprinoid fish is A. hydrophila (Palmeiro & Roberts, 2009). Very recently, Abdel-Latif and Khafaga (2020) noticed mass mortality of cultured Nile tilapia and considerable economic losses due to the infections induced by A. hydrophila. Fluctuations in physico-chemical parameters such as salinity, temperature, pH, dissolved oxygen and water conductivity of cultured system could severely increase the rate of aeromonad infection in fish (Mzula et al., 2019).

“…First, various human pathogens and spoilage microorganisms as well as ARB have been detected in water samples collected from the fish living/rearing environment. The reported ARB include Salmonella spp., Aeromonas spp., Acinetobacter spp., Pseudomonas spp., Bacillus spp., Pseudoalteromonas spp., Proteus spp., and many others (Budiati et al., 2013; Hoa et al., 2011; Naviner et al., 2011; Ranjbar, Salighehzadeh, & Sharifiyazdi, 2019; Shah, Colquhoun, Nikuli, & Sorum, 2012; Zdanowicz, Mudryk, & Perlinski, 2020). Furthermore, ARGs were detected in water microbiota using culture‐independent methods, for example, quantitative PCR (qPCR) and shotgun metagenomic sequencing (Klase et al., 2019; Seyfried, Newton, Rubert, Pedersen, & McMahon, 2010; Shah et al., 2012; Wang et al., 2018; Xiong et al., 2015; Zeng, Liao, Terhune, & Wang, 2019).…”

Microorganisms play a crucial and unique role in fish and fish product safety. The presence of human pathogens and the formation of histamine caused by spoilage bacteria make the control of both pathogenic and spoilage microorganisms critical for fish product safety. To provide a comprehensive and updated overview of the involvement of microorganisms in fish and fish product safety, this paper reviewed outbreak and recall surveillance data obtained from government agencies from 1998 to 2018 and identified major safety concerns associated with both domestic and imported fish products. The review also summarized all available literature about the prevalence of major and emerging microbial safety concerns, including Salmonella spp., Listeria monocytogenes, and Aeromonas hydrophila, in different fish and fish products and the survival of these pathogens under different storage conditions. The prevalence of antibiotic‐resistant bacteria (ARB) and antibiotic‐resistant genes (ARGs), two emerging food safety concerns, is also reviewed. Pathogenic and spoilage microorganisms as well as ARB and ARGs can be introduced into fish and fish products in both preharvest and postharvest stages. Many novel intervention strategies have been proposed and tested for the control of different microorganisms on fish and fish products. One key question that needs to be considered when developing and implementing novel control measures is how to ensure that the measures are cost and environment friendly as well as sustainable. Over the years, regulations have been established to provide guidance documents for good farming and processing practices. To be more prepared for the globalization of the food chain, harmonization of regulations is still needed.
