We provide a global overview of the intestinal bacteriome Litopenaeus vannamei in two rearing systems and after an oral challenge by White spot syndrome virus (WSSV). By using high-throughput 16S rRNA gene sequencing technology, we identified compared composition abundance bacterial communities from midgut shrimp reared super-intensive biofloc technology (BFT) clear seawater system (CWS). The predominant group belonged to phylum Proteobacteria, followed phyla Bacteroidetes, Actinobacteria,...
Resumo No Brasil, a tainha Lebranche é espécie Mugilidae mais importante para indústria pesqueira. Contudo, recentemente foi recomendada classificação como quase ameaçada. Neste sentido, aquicultura surge uma ferramenta poderosa conservação e desenvolvimento dos recursos naturais. O presente estudo avaliou influência de diferentes temperaturas durante larvicultura Mugil liza seus efeitos tardios no gonadal na quantificação hormonal após 24 meses. Inicialmente, os ovos fecundados (45 L-1)...
Abstract In Brazil, the Lebranche mullet is most important Mugilidae species for fishing industry. However, recently, has been recommended classification as near threatened. this sense, aquaculture emerged a powerful tool natural resource conservation and development. The present study evaluated influence of different temperatures during Mugil liza larviculture their late effects on gonadal development hormonal quantification after 24 months. fertilized eggs (45 L-1) were initially kept in...
Animal and human wastewater can potentially contaminate water sources the treatment of drinking may not effectively remove all contaminants, especially viruses. The purpose present study was to evaluate viral contamination used for animal consumption in city Concórdia, located southern Brazil. Porcine circovirus type 2 (PCV2), porcine adenovirus (PAdV), (HAdV) norovirus (NoV) were searched using quantitative polymerase chain reaction (qPCR). HAdV-positive samples tested infectivity by plaque...
Since the recent discovery of Samba virus, first representative family Mimiviridae from Brazil, prospecting for mimiviruses has been conducted in different environmental conditions Brazil. Recently, we isolated using Acanthamoeba sp. three new mimiviruses, all lineage A amoebal mimiviruses: Kroon virus urban lake water; Amazonia Brazilian Amazon river; and Oyster farmed oysters. The aims this work were to sequence analyze genome these (mimi-BR) update analysis genome. genomes 97%-99%...
The super-intensive BioFloc Technology (BFT) system has been highlighted as a promising eco-friendly alternative to the traditional shrimp rearing systems. To gain insight into impact of environmental conditions on intestinal immunity, we assessed expression profile key immunological genes in midgut Litopenaeus vannamei reared two contrasting culture systems: indoor BFT and outdoor intensive Green-Water System (GWS). From 30 analyzed genes, levels 25 were higher than GWS. main functional...
Temperature is a limiting factor to the development of fish eggs and larvae. The aim this study was define optimal temperature for egg incubation, larval survival Mugil liza Artificial fertilization performed with manual extrusion oocytes semen. After blastopore enclosure, fertilized were incubated at 17, 20, 23, 26 or 29°C in beakers. Larval (200 L−1), hatching rates (100 L−1) RNA/DNA ratio evaluated. best 23.2°C 23.9°C obtained rate. At 16.5°C, 70% larvae died, 28.4°C, mortality 40%. time...
Temperature is a limiting factor to the development of fish eggs and larvae. The aim this study was define optimal temperature for egg incubation, larval survival Sardinella brasiliensis Eggs were obtained by natural spawn collected after blastopore enclosure. Fertilized incubated at 17, 20, 23, 26 29 or 32°C in beakers. Larval (200 L−1), hatching rates (100 L−1) RNA/DNA ratio evaluated. best 28°C, rate 24.7°C, 100% larvae died 18.4°C. time mouth opening (24 51 h) moment eye pigmentation 45...
The Lebranche mullet Mugil liza is a marine fish of great importance for artisanal and industrial fishing, as well aquaculture. use live feeds during the larviculture phase significant component production costs. present study evaluated effects feeding transition on different larval stages M. liza, from combined supply feed (Brachionus rotundiformis + Artemia franciscana) inert (Artemia franciscana diet) until weaning to only diet. A total 3240 larvae (weight 0.0133 ± 0.0062 g length 0.793...

Numerous studies have demonstrated the profile of infection and symptoms related to COVID-19 that occur with pulmonary manifestations (such as Acute Respiratory Syndrome), digestive symptoms, anosmia, ageusia. Many comorbidities been associated deaths severe cases disease, such diabetes, hypertension, obesity, heart disease. However, many questions remain unanswered, especially association disease severity hypovitaminosis D. Vitamin D deficiency is widely found in patients Intensive Care...
Abstract The Mugil liza mullet is a pelagic fish, widely distributed on the Atlantic coast of South America. Its female gonads have high value and market demand, which makes monosexual breeding desirable. objective this work was to use hormone 17β-estradiol orally in juveniles increase proportion females, evaluating zootechnical performance first sexual maturation. There were five treatments: 60, 80, 100, 120 140 mg per kg diet control without for 60 days. Each experimental unit stocked with...
