“…is consistent with the report of Costa et al [14], which suggested that phenotypic identification alone often leads to misidentification of microorganisms and/or wrong diagnosis of infections. Knowledge of the true identity of potential bacterial pathogens is more often than not critical to effective treatment, management, and control of bacterial infections [15].…”

Introduction: The antibiograms of Vibrio species isolated from abattoir effluents in the Niger Delta region of Nigeria were investigated with respect to their public health significance. Methodology: Vibrio species were isolated and identified using standard microbiological and molecular techniques, while antibiogram of isolates was tested and interpreted using the disk diffusion method described by the Clinical and Laboratory Standards Institute. Results: Of 150 presumptive isolates, 48 (32%) were confirmed to be Vibrio spp. by PCR; of these, 23 (47.9%) were V. cholerae, 11 (22.9%) were V. fluvialis, 8 (16.7%) were V. vulnificus, and 6 (12.5%) were V. parahaemolyticus. The antibiogram revealed that Vibrio species were generally resistant to ampicillin (60%-67%), trimethoprim (80%-100%), and tetracycline (60%-83%), whereas they were sensitive to ceftriaxone (86%-100%), the aminoglycosides (67%-100%), imipenem (86%-100%), ofloxacin (83%-100%), and chloramphenicol (67%-100%). The isolates exhibited multiple antibiotic resistance (MAR) with an average MAR index of 0.23. Conclusions: This study demonstrated that abattoir effluents are important reservoirs for multidrug-resistant Vibrio species that might be considerable contributors to the recurrent episodes of epidemic cholera and non-Vibrio cholera infections in Nigeria.

“…(Rattanachuay, Kantachote, Tantirungkij, Nitoda & Kanzaki , ). The use of antibiotics for shrimp farming is not recommended for controlling disease (Serrano ; Albuquerque‐ Costa, Araujo, Souza & Vieira ) because of the potential to build up antibiotic resistant strains in the sediments (Defoirdt, Sorgeloos & Bossier ). Hence, this study has focused on the ability of extracellular antivibrio compounds especially from probiotic PNSB to inhibit shrimp pathogenic bacteria ( Vibrio spp.).…”

In vitro and in vivo selection of probiotic purple nonsulphur bacteria with an ability to inhibit shrimp pathogens: acute hepatopancreatic necrosis disease-causing Vibrio parahaemolyticus and other vibrios

et al. 2016

Shrimp cultivation has been faced with huge losses in productivity caused by infectious shrimp pathogenic vibrios, especially Vibrio parahaemolyticus that causes acute hepatopancreatic necrosis disease (AHPND). Hence, purple nonsulphur bacteria (PNSB) were isolated from shrimp ponds for investigating their abilities to control shrimp pathogenic Vibrio spp. and their use as probiotics for sustainable shrimp cultivation. Based on their probiotic properties, strains S3W10 and SS15 were selected because of their strong abilities to produce amylase, gelatinase and vitamin B12. However, only three PNSB strains (SS15, TKW17 and STW181) strongly inhibited V. harveyi_KSAAHRC and V. vulnificus_KSAAHRC including V. parahaemolyticus AHPND strains by secreting antivibrio compounds. Four selected PNSB also grew in the presence of pancreatic enzymes, and they were identified as Rhodobacter sphaeroides for strains S3W10, SS15 and TKW17 and Afifella marina for strain STW181. The effects of a mixed culture were also investigated as follows: T1 (S3W10 + SS15), T2 (S3W10 + TKW17) and T3 (S3W10 + STW181) on postlarval white shrimp (Litopenaeus vannamei) for 60 days by comparison with a control. All three probiotic PNSB sets significantly improved the digestive enzyme activities and shrimp growth with their proliferation in shrimp gastrointestinal tract although the shrimp survival was not significantly different. They also significantly reduced the cumulative mortality of shrimp exposed to a virulent AHPND strain (V. parahaemolyticus SR2). This is the first to conclude that selected probiotic PNSB strains have great potential to be used for shrimp cultivation to control vibrios including AHPND strains.

“…Antibiotics have been largely used in intensive aquaculture, as well for finfish [ 102 , 103 ], shrimp [ 104 , 105 , 106 , 107 ] or shellfish cultures [ 108 , 109 ]. However, as for humans and terrestrial animals, bacterial resistance in aquaculture is increasing and most antibiotics are less effective [ 110 , 111 , 112 ]. The presence of drug residues in tissues of aquatic animals and the risk of transferring resistant bacteria to humans have led to a great concern about the use of antibiotics for public health [ 113 ].…”

Antimicrobial Compounds from Eukaryotic Microalgae against Human Pathogens and Diseases in Aquaculture

The search for novel compounds of marine origin has increased in the last decades for their application in various areas such as pharmaceutical, human or animal nutrition, cosmetics or bioenergy. In this context of blue technology development, microalgae are of particular interest due to their immense biodiversity and their relatively simple growth needs. In this review, we discuss about the promising use of microalgae and microalgal compounds as sources of natural antibiotics against human pathogens but also about their potential to limit microbial infections in aquaculture. An alternative to conventional antibiotics is needed as the microbial resistance to these drugs is increasing in humans and animals. Furthermore, using natural antibiotics for livestock could meet the consumer demand to avoid chemicals in food, would support a sustainable aquaculture and present the advantage of being environmentally friendly. Using natural and renewable microalgal compounds is still in its early days, but considering the important research development and rapid improvement in culture, extraction and purification processes, the valorization of microalgae will surely extend in the future.
