The aquafeed industry evolved alongside fish farming, utilizing scientific and technological advancements to incorporate a variety of feed additives, supplements, alternative ingredients in the nutrition feeding aquaculture. These advances played significant role improving production, health, welfare farmed fish. Recent research Brazil highlighted importance using such as vitamins, minerals, amino acids, ensure that receive all necessary nutrients for growth health. Functional additives can...
Helminth parasites represent a significant threat to the health of human and animal populations, there is growing need for tools treat, diagnose, prevent these infections. Recent work has turned gut microbiome as utilitarian agent in this regard; components may interact with influence their success gut, meaning that encode new anthelmintic drugs. Moreover, parasite infections restructure microbiome's composition consistent ways, implying be useful diagnosing infection. The innovation...
The effect of Goezia leporini Martins & Yoshitoshi, 2003 (Nematoda: Anisakidae) infection on the haematological characteristics cultivated Leporinus macrocephalus (Osteichthyes:Anostomidae) was studied. Paleness gills, kidneys, liver and heart, black spots kidney accumulation fluid in visceral cavity, stomach intestines were observed. Gall bladder content had pale translucent aspect. Strong slight positive correlations between number nematodes fish weight estimated within 0-100g 100-200g...
This study evaluated the haematological changes in Nile tilapia experimentally infected with 1 x 10³ and 10(6) colony-forming units (CFU)/mL of Enterococcus sp. swim bladder. The experiment consisted four treatments triplicates: non-injected fish (NI); injected mL sterile saline solution 0.65% (SAL); CFU/mL diluted saline. Twenty-four hours after injection, were anesthetized blood collected. tests included red cell (RBC) white (WBC) counts, hematocrit, number total thrombocytes, differential...
Intensive culture of the hybrid surubim (Pseudoplatystoma corruscans × Pseudoplatystoma fasciatum) in Brazil is responsible for occurrence diseases and consequent economic losses. However, causative agents are not well known. The objective this study was to isolate characterize pathogenic agent mortalities cultured demonstrate its virulence. Ten fish from a farm located Mato Grosso do Sul State (Brazil) were collected 14 haemolytic bacteria characterized as Aeromonas hydrophila isolated...
The dietary supplementation of prebiotics, probiotics and symbiotic in hybrid surubins (a Pseudoplatystoma corruscans P. fasciatum cross) was evaluated for the effects on their autochthonous intestinal microbiota haematological immunological parameters. A total 160 fish were divided into four treatment groups with replicates each. fed following diets 15 days: control diet without supplementation; 0.5% inulin (prebiotic) Weissella cibaria (CPQBA 001-10 DRM 02) (7.87 ± 0.2 log CFU g−1) or W....
Abstract In the aquatic environment, fish are subject to different pollutants and environmental variations that favour stress on animals, making them vulnerable pathogens. Fish parasites excellent biological indicators of quality, as their parasitic population may increase or decrease in response changes water parameters and/or presence pollutants. Ectoparasites considered quality because they have a monoxenic life cycle with high reproductive rates been responsible for immediate biota....
The efficacy of a polyvalent bacterin vaccine against Aeromonas hydrophila, Pseudomonas aeroginosa and Enterococcus durans administered by different routes in Nile tilapia was assessed analyzing hematological immunological parameters 7 21 days after vaccination. Treatments consisted of: non-vaccinated tilapia; vaccinated intraperitoneal injection with 2x10(8) formalin-inactivated bacteria·mL-1; orally 2x10(7) bacteria·g-1, feed for 5 days; immersion bath bacteria·mL-1, 20 minutes. Vaccinated...
The effect of a Lactobacillus plantarum-supplemented diet on shrimp growth, digestive tract bacterial microbiota, survival, and some hemato-immunological parameters after an experimental challenge with Vibrio harveyi was studied. No difference (P>0.05) observed in survival (80±6%) final weight (6.63±0.56g) 60 days feeding trial. Total bacteria count spp. the were not diferent until day 40, but they lower (P<0.05) probiotic-supplemented group 60. lactic higher 20 group. Ten hours V....
Although human T-cell lymphotropic viruses (HTLV-1/2) were described over 30 years ago, they are relatively unknown to the public and even healthcare personnel. HTLV-1 is associated with severe illnesses, these occur in only approximately 10% of infected individuals, which may explain lack knowledge about them. However, cohort studies showing that a myriad other disease manifestations trouble individuals cause higher expenditures healthcare. Testing donated blood for HTLV-1/2 started soon...
Abstract This work evaluated the effects of dietary supplementation A-Live (phytogenic) either individually or in combination with Aquaform (potassium diformate, acidifier) on juvenile Nile tilapia ( Oreochromis niloticus ) growth performance, innate immune parameters, gut microbiome, and resistance against Francisella noatunensis subsp. orientalis challenge. Each experimental group contained 140 fishes (34.3 ± 0.33) two 150L tanks. The design consisted five groups: a negative control;...
