1. Performance and immunological resistance of Litopenaeus vannamei fed a β-1,3/1,6-glucan-supplemented diet after per os challenge with the Infectious myonecrosis virus (IMNV)
This study determined the efficacy of a β-1,3/1,6-glucan source on the survival, growth, and immunological responses of Litopenaeus vannamei challenged with infectious myonecrosis virus (IMNV). The work was conducted in 20 tanks of 500 L with clear water with constant recirculation and aeration. Shrimp weighing 2.6±0.4 g were stocked at 100 animals/m2 and

2. PURIFICAÇÃO DO VÍRUS DA MIONECROSE INFECCIOSA (IMNV) EM CAMARÃO MARINHO DA ESPÉCIE LITOPENAEUS VANNAMEI E DESENVOLVIMENTO DE TÉCNICAS SOROLÓGICAS PARA O SEU DIAGNÓSTICO. / PURIFICATION OF INFECTIOUS VIRUS myonecrosis (IMNV) MARINE SPECIES IN SHRIMP Litopenaeus vannamei AND DEVELOPMENT serological techniques FOR YOUR DIAGNOSIS
O objetivo deste estudo foi purificar e caracterizar o agente viral da mionecrose infecciosa (IMN), através de técnicas de baixo custo. Para tanto, foram utilizados camarões oriundos de duas carciniculturas no interior do Ceará, que apresentavam sintomas da mionecrose. As amostras foram estocadas a -20C, e encaminhadas para o Centro de Estudo e Diagnóst

3. First report of White spot syndrome virus in farmed and wild penaeid shrimp from Lagoa dos Patos estuary, southern Brazil
In this study, we detected White spot syndrome virus (WSSV) in wild Farfantepenaeus paulensis collected in the Lagoa dos Patos estuary and cultivated Litopenaeus vannamei. This is the first report of WSSV in F. paulensis from Lagoa dos Patos and farmed L. vannamei shrimps in Rio Grande do Sul.

4. Detection of major capsid protein of infectious myonecrosis virus in shrimps using monoclonal antibodies.
Infectious myonecrosis virus (IMNV) has been causing a progressive disease in farm-reared shrimps in Brazil and Indonesia. Immunodiagnosticmethods for IMNVdetection, although reliable, are not employed currently becausemonoclonal antibodies (MAbs) against this virus are not available. In this study, a fragment of the IMNVmajor capsid protein gene, comprising

5. Análise quantitativa da carga viral do vírus da Mionecrose infecciosa (IMNV) em diferentes tecidos do camarão marinho Litopenaeus vannamei naturalmente infectado
O camarão marinho (Litopenaeus vannamei) é a mais importante espécie de camarão em volume na aqüicultura mundial. Entretanto, nas últimas décadas, surtos de diversas doenças especialmente as de etiologia viral foram responsáveis por perdas econômicas significativas,ameaçando a sustentabilidade da carcinicultura mundial. Em 2004, a carcinicultura b

6. Susceptibility of Rosa Shrimp Farfantepenaeus subtilis (Pérez-Farfante, 1967) to Infectious myonecrosis virus (IMNV) / Susceptibilidade do Camarão Rosa Farfantepenaeus subtilis (Pérez-Farfante, 1967) ao Vírus da Mionecrose Infecciosa (IMNV)
Viral diseases are causing great damage in shrimp farming. With the IMN virus emergence in Northeastern Brazil in 2002, the shrimp producers faced an unknown disease that caused significant losses for the industry. Thus, a better knowledge about this disease and the investigation of how other species of shrimp are affected by the IMN virus will be an importa

7. Metodologia para gestão do risco da Síndrome de Taura no Brasil devido à importação de pós-larvas de camarão
Risk analysis is a science-based method to assist decision-makers make consistent and transparent arguments and decisions in face of uncertainty and natural variability. The concept of risk involves the likelihood of the occurrence of an adverse effect and the magnitude of its consequences. This study developed a methodology for qualitative risk assessment o

8. Performance and immune resistance of white shrimp Litopenaeus vannamei fed a diet rich in B-1, 3 / 1, 6 - glucan and L-ascorbic acid monophosphate front of infectious myonecrosis virus (IMNV) / Desempenho e da resistÃncia imunolÃgica do camarÃo branco Litopenaeus vannamei alimentado com uma dieta rica em B-1,3/1,6 â Glucano e Ãcido L-ascÃrbico monofosfato frente ao vÃrus da mionecrose infecciosa (IMNV)
Desde 2002 que um novo agente patogÃnico denominado de VÃrus da Mionecrose Infecciosa (IMNV) vem causando significativas perdas econÃmicas em fazendas de camarÃo na RegiÃo Nordeste do Brasil. Ao contrÃrio dos vertebrados, os camarÃes nÃo possuem um sistema imunolÃgico com memÃria adaptativa, no entanto possuem um sistema imune inato, apresentando r

9. InvestigaÃÃo da ocorrÃncia dos vÃrus da sÃndrome da mancha branca (WSSV) e da infecÃÃo hipordermal e necrose hematopoiÃtica (IHHNV) em camarÃes coletados em Ãreas sob influÃncia de efluentes da carcinicultura / Investigation of occurrence of the virus of white spot syndrome (WSSV) infection and hipordermal and haematopoietic necrosis (IHHNV) in shrimps collected in areas under influence of effluents from shrimp
As principais enfermidades virais detectadas na carcinicultura mundial sÃo a SÃndrome da Mancha Branca (WSSV), InfecÃÃo Hipodermal e Necrose HematopoiÃtica (IHHNV), SÃndrome de Taura (TSV) e a SÃndrome da CabeÃa Amarela (YHV), esta Ãltima sem registro nos cultivos brasileiros. As doenÃas virais acima relacionadas nÃo estÃo restritas ao ambiente d

10. Susceptibilidade do camarÃo-rosa Farfantepenaeus subtilis (Perez-Farfante, 1967) ao vÃrus da infecÃÃo hipodermal e necrose hematopoiÃtica (IHHNV) / Susceptibility of shrimp pink Farfantepenaeus subtilis (Perez-Farfante, 1967) to virus infection hipodermal and haematopoietic necrosis (IHHNV)
Diseases are the main biological factor that can limit and discourage the shrimp culture worldwide. Virus infection is the main cause of impact and economic losses registered in this sector. The Infectious Hypodermal and Hematopoietic Necrosis Virus (IHHNV) occurs in both wild and cultured shrimp, mainly in the juvenile and sub-adult phases, although it does

12. Protection of Penaeus monodon against White Spot Syndrome Virus by Oral Vaccination
White spot syndrome virus (WSSV) occurs worldwide and causes high mortality and considerable economic damage to the shrimp farming industry. No adequate treatments against this virus are available. It is generally accepted that invertebrates such as shrimp do not have an adaptive immune response system such as that present in vertebrates. As it has been demo
