Abstract

Antibiotic resistance is an emerging concern, leading to the search for alternative antibacterial agents. Scientists looking for potential alternatives to antibiotics see promise in the antimicrobial propensity of microalgae. We investigated the antibacterial potentials of Tetraselmis, Chlorella and Nannochloropsis against pathogenic bacteria from chicken, dogs, and fish. We identified E. coli, Stenotrophomonas sp., Streptococcus sp., Staphylococcus sp., Aeromonas sp. and Lysinibacillus sp. by colony characteristics, Gram staining and VITEK-2 tests. Results demonstrated that Tetraselmis was highly sensitive against Stenotrophomonas sp. (p < 0.0001) and E. coli (p < 0.001) from chicken, and Staphylococcus sp. (p < 0.01) from dogs. Moreover, Chlorella was highly sensitive against E. coli (p < 0.0001) from dogs. All the bacteria isolated from chicken were moderate to highly sensitive to Chlorella. Nannochloropsis was marginally sensitive to all the bacteria isolated from chickens and dogs. The minimum inhibitory concentration values indicate that a minimum of 10 mg/ml of Tetraselmis can suppress the growth of Aeromonas sp. from fish and Chlorella can suppress E. coli and Stenotrophomonas sp. from chicken. Results indicate that native microalgae may have an active somatic or secretory component(s) that prevent bacterial cell division and/or induce lysis. Advanced studies should be performed to identify the active component for the development of newer and sustainable antimicrobial drugs.
