Resumo: | Shrimp farming on no water exchange systems with bioflocs (BFT) has been shown an alternative to avoid recurrent outbreaks of exotic infectious diseases. Its immunostimulatory role has already been proven in several studies, protecting shrimp by activating several factors present in its immune system and conferring greater resistance to infection. Among these agents, White spot syndrome (WSSV) and Infectious myonecrosis (IMNV) viruses have historically already caused billionaire losses and are still widespread worldwide, including Brazilian shrimp-producing states. Our objective was to evaluate the effect of the use of biofloc technology on experimentally infected marine shrimp by WSSV and IMNV. The animals were divided into three treatments, one with WSSV (W) immersion infection, another with infection by IMNV contaminated tissue (I), a third by the two anterior (IW) and the negative control (C), without viral challenge. At the end of the experiment (day 20), the mortality rate did not differ statistically between any groups. PCR analysis showed no positivity for WSSV in any sample, but there were positive animals for IMNV in treatments C (23.8%) and W (8.7%). However, no animal presented macro and microscopic alterations, indicating the non-development of the infection. These results point to a resistance to infection by the animals, suggesting that bioflocs can act as a barrier against infection. |

Dentre estes agentes, os vírus da Síndrome da mancha branca (WSSV) e da Mionecrose infecciosa (IMNV) historicamente já causaram perdas na casa dos bilhões de dólares e hoje estão difundidos em todo o mundo, incluindo os estados brasileiros produtores de camarão. Nosso objetivo foi avaliar o efeito do uso da tecnologia de bioflocos em camarão marinho infectado experimentalmente pelo WSSV e IMNV. Os animais foram distribuídos em três tratamentos, sendo um com infecção por imersão pelo WSSV (W), um segundo com infecção via ingestão pelo IMNV (I), um terceiro pelas duas vias anteriores (IW), além do controle negativo (C), sem desafio viral. Ao final do experimento (dia 20), a taxa de mortalidade não diferiu estatisticamente entre nenhum grupo. A análise por PCR não acusou positividade para WSSV em nenhuma amostra, porém houve animais positivos para IMNV nos tratamentos C (23,8%) e W (8,7%). No entanto, nenhum animal apresentou alterações macro e microscópicas, o que indica o não desenvolvimento da infecção. Estes resultados apontam uma resistência à infecção por parte dos animais, sugerindo que os bioflocos podem agir como barreira contra a infecção.Submitted by Mario BC (mario@bc.ufrpe.br) on 2019-12-10T14:39:43Z No. of bitstreams: 1 Leandro Cavalcanti Souza de Melo.pdf: 1090487 bytes, checksum: 86f7ed82d2de5bb61ea2b11d554e30b0 (MD5)Made available in DSpace on 2019-12-10T14:39:43Z (GMT).

Shrimp farming on no water exchange systems with bioflocs (BFT) has been shown an alternative to avoid recurrent outbreaks of exotic infectious diseases. Its immunostimulatory role has already been proven in several studies, protecting shrimp by activating several factors present in its immune system and conferring greater resistance to infection. Among these agents, White spot syndrome (WSSV) and Infectious myonecrosis (IMNV) viruses have historically already caused billionaire losses and are still widespread worldwide, including Brazilian shrimp-producing states. Our objective was to evaluate the effect of the use of biofloc technology on experimentally infected marine shrimp by WSSV and IMNV. The animals were divided into three treatments, one with WSSV (W) immersion infection, another with infection by IMNV contaminated tissue (I), a third by the two anterior (IW) and the negative control (C), without viral challenge. At the end of the experiment (day 20), the mortality rate did not differ statistically between any groups. PCR analysis showed no positivity for WSSV in any sample, but there were positive animals for IMNV in treatments C (23.8%) and W (8.7%). However, no animal presented macro and microscopic alterations, indicating the non-development of the infection. These results point to a resistance to infection by the animals, suggesting that bioflocs can act as a barrier against infection. |
