“…(Starliper et al, 2015). An earlier study by Gallani et al (2020) observed that in comparison to basil oil, palmarosa oil has higher inhibitory efficacy (lower MIC/MBC) on Aeromonas hydrophila isolated from diseased fish. Several other reports also indicate that palmarosa oil is effective against both Gram‐positive and Gram‐negative bacteria (Santamarta et al, 2020; Morris, 2021).…”

“…Several studies have shown the antimicrobial potential of plant‐derived essential oils (EOs) on various bacterial pathogens such as Aeromonas spp., Salmonella spp., Staphylococcus epidermidis and Escherichia coli (Fu et al, 2007; Olaimat et al, 2019; Monteiro et al, 2021). Palmarosa, basil and rosemary EOs have been shown to possess antibacterial activity against Aeromonas species (Gallani et al, 2020; El‐Ekiaby 2019; Starliper, 2015; Tural et al, 2019). Most of these studies have determined the minimum inhibitory concentration (MIC)/minimum bactericidal concentration (MBC) of EOs against bacterial strains and/or their suggested use as an alternative to antimicrobials.…”

Aims To investigate the antibacterial activity of three (palmarosa, basil and rosemary) essential oils (EOs) on Aeromonas veronii and Aeromonas caviae, and determine minimum inhibitory concentration (MIC) of potent EO against tetracycline and sulfonamide resistant strains. Methods and Results Palmarosa oil (PMO) showed significantly (p < 0.05) higher inhibition zones against both A. veronii and A. caviae (n = 30) than basil and rosemary in the disk diffusion assay. The MIC (% v/v) of PMO ranged from 0.008% to 1.00%. The mean MIC was significantly higher for A. caviae (0.48 ± 0.24%) than A. veronii (0.21 ± 0.15%). Further, the MIC of PMO was compared in six groups: Group 1: Tetracycline Resistant A. veronii (TRV); Group 2: Tetracycline Resistant A. caviae (TRC); Group 3: Sulfonamide Resistant A. veronii (SRV); Group 4: Sulfonamide Resistant A. caviae (SRC); Group 5: Susceptible A. veronii (SV) and Group 6: Susceptible A. caviae (SC). No significant differences were observed between overall resistant (TRV+ SRV) and susceptible A. veronii (SV). However, in A. caviae, the resistant group had a lower MIC than the susceptible group. Moreover, the MIC was significantly lower for TRC (0.31 ± 0.11%) as compared to SRC (0.46 ± 0.10%). The time of kill of PMO for both the species of Aeromonas was 20–30 min. Conclusion Palmarosa oil exhibited significantly higher activity on A. veronii than A. caviae. The resistant strains of A. caviae were inhibited at a lower concentration than susceptible strains. Significance and Impact of the Study Palmarosa oil could be explored as an alternative antimicrobial agent for mitigating antimicrobial resistance and managing Aeromonas infection in fish and their risks to public health.

“…As a result of intensive production system and imbalance of host/pathogen/environment relationship, bacterial diseases caused by Aeromonas hydrophila are considered one of the most important in tambaqui culture (Gallani et al, 2020;Tavares-Dias & Martins, 2017). Consequently, the indiscriminate use of antibiotics causes resistance to drugs, immunesuppression, environmental contamination and risks to human health, with consequent economic losses (Gallani et al, 2020;Pauzi et al, 2020;Pessoa et al, 2019).…”

The fish farm has presented rapid advance in the last years, and fish consumption provides one of the main source of proteins and nutrients that are essential for human health (FAO, 2020). The Brazilian native fish that include Colossoma macropomum, popularly known as tambaqui, Piaractus mesopotamicus (pacu) and their hybrids, contributed with 278,671 tonnes or 34.7% of the total fish production (PEIXE BR, 2021). Among the main native farmed species, C. macropomum stands out due to the availability technologies for production

Within the rich diversity of South American freshwater fish, Colossoma macropomum (Characiformes: Serrasalmidae), known as tambaqui, cachama or blackfin pacu, can reach 30 kg, is a traditional product in regional fish markets and has drawn the attention of fish farmers since the 1930s. Considerable progress achieved in different fields of aquaculture science has contributed to the growth of tambaqui production.
