“…The study by Sebastião et al (2020) simultaneously verified the effectiveness of the anthelmintic and the consequences on the health of the fish, in such a way that no changes were found in the blood and biochemical parameters of the fish submitted to the experiment with Acantex. Regarding in vivo tests, no concentration (3, 4 or 5 mg kg −1 ) interfered in the N .…”

Acanthocephalans parasites in farmed fish in Brazil: A review

2021

View full text Add to dashboard Cite

Studies of acanthocephalans have increased due to outbreaks in Brazilian fish farms. This review aimed to compile results of studies carried out in Brazil, which have reported occurrences of acanthocephalans in fish from fish farms, discuss histopathological and haematological implications, and describe the different treatments in use to combat these parasites. Scientific articles, short communications, monographs, dissertations and theses are included. Eight species of acanthocephalans have been recorded: Neoechinorhynchus buttnerae, Neoechinorhynchus sp. and Echinorhynchus jucundus, Echinorhynchus gomesi, Polyacanthorhynchus macrorhynchus, Polyacanthorhynchus sp., Pomphorhynchus sp., and Quadrigyrus sp. Studies of histopathology and haematology have reported perforations, inflammation and changes in host intestines and immune cells, due to infection with acanthocephalans. Early‐stage testing, both in vitro and in vivo, has shown essential oils, oleoresins and plant extracts to be highly efficacious in combating acanthocephalans. However, there are no national records regulating the use of these anthelmintics in commercial fish farms. In view of this, we are recommending good management practices, including (a) cleaning tanks after fish removal (drying the soil and adding hydrated lime); (b) crop cycles with time intervals, (c) acquisition of healthy fry followed by quarantine; and (d) controlled feeding.

“…Acanthocephalans were considered dead when they remained motionless even after external stimuli. The test was considered complete after 8 hours of observation, which is an | 149 approximate time described in other studies in the literature (SOUZA et al, 2018;OLIVEIRA et al, 2019;SANTOS et al, 2021;SEBASTIÃO et al, 2021).…”

Neoechinorhyncus buttnerae is among the main causative agents of diseases in tambaqui (Colossoma macropomum) and has caused great losses in fish farming. Although important, there is still no effective treatment protocol for acanthocephalosis. Therefore, the aim of this study was to evaluate the in vitro anthelmintic activity of Chenopodium ambrosioides (mastruz) in the control of Neoechinorhyncus buttnerae. Parasites were collected from the intestine of naturally infected animals and randomly distributed in Petri dishes containing the following treatments in triplicate and standardized in 5 mL of RPMI1640 medium: TR1 (RPMI+spray-dried extract of mastruz 10%); TR2 (RPMI+spray-dried extract 5%); positive control (RPMI+levamisole 15 mg/mL); negative control (RPMI). The parasites were kept at room temperature and observed every 15 min, and were considered dead when they remained motionless even after external stimuli. Body deformities were observed in parasites after exposure to treatments (TR1 and TR2), and both treatments with spray-dried extract of mastruz were effective in controlling acanthocephalans in the first 15 min of the experiment. Therefore, mastruz has been shown to be an effective alternative for the control of N. buttnerae and has the potential for continuing in vivo studies with the aim of developing a therapeutic protocol.

“…Recent in vitro studies have reported the potential of natural plant extracts 315 organic acids, essential oils 316 and oleoresins 317 to kill the acanthocephalan, and in vivo studies have shown that a commercial phytobiotic 318 and plant essential oils 319 have reduced the burden of parasitism at different levels. Recent in vitro studies have reported the potential of natural plant extracts, 315 organic acids, essential oils 316 and oleoresins 317 to kill the acanthocephalan, and in vivo studies have shown that a commercial phytobiotic 318 and plant essential oils 319 have reduced the burden of parasitism at different levels. However, there is still no consensus on the effectiveness of acanthocephalosis control in farmed tambaqui based only on fish medication, mainly because it is a disease caused by infected zooplankton that are dispersed three‐dimensionally throughout the farming environment, making disease prevalence and relapse imminent if preventive measures are not in effect.…”

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.
