| Shrimp aquaculture has been dramatically affected by many pathogenic diseases, mainly caused by five viruses: IHHNV, YHV, TSV, WSSV, and IMNV. Here we provide a state-of-the-art overview of these shrimp viruses, with emphasis on distribution, pathology, morphology, and genomic organization, in addition to current diagnostic methods and intervention practices. |

| Uno de los principales problemas del cultivo del camarón blanco del Pacífico, Litopeneaeus vannamei, es la susceptibilidad de esta especie a diversas enfermedades virales, que pueden conducir a grandes mortalidades y/o pérdidas económicas. En este trabajo se reportan los resultados obtenidos en la ejecución de los muestreos periódicos y chequeos de cuarentenas correspondientes al programa de vigilancia, desde la primera introducción de esta especie en Cuba en 2003 hasta el 2009. Para ello se emplearon técnicas de análisis en fresco, histológicas y de biología molecular. En este período, no se detectó ninguno de los virus de crustáceos que son de declaración obligatoria por la Organización Mundial de la Salud Animal (OIE, de sus siglas en francés): el virus... |

| Viruses inhabiting the surface mucus layer of scleractinian corals have received little ecological attention so far. Yet they have recently been shown to be highly abundant and could even play a pivotal role in coral health. A fundamental aspect that remains unresolved is whether their abundance and diversity change with the trophic state of their environment. The present study examined the variability in the abundance of viral and bacterial epibionts on 13 coral species collected from 2 different sites in the Ha Long Bay, Vietnam: one station heavily affected by anthropogenic activity (Cat Ba Island) and one protected offshore station (Long Chau Island). In general, viral abundance was significantly higher in coral mucus (mean = 10.6 +/- 2.0 x 10(7)... |

| ABSTRACT Despite the widespread distribution of the Cassava common mosaic virus (CsCMV) in Brazil, little is known about the losses it causes in yield. The effect of CsCMV on different varieties was evaluated by reference to several agronomic traits. Four field trials were established in 2012/2013 and 2013/2014 using six varieties of cassava. Following mechanical inoculation with CsCMV, the presence of the virus was confirmed using the ELISA assay. The evaluated traits were plant height (PH), dry matter content (DMC), harvest index (HI), aerial part yield (APY), root yield (RoY), and starch yield (StY) in both inoculated and non-inoculated plants. Overall, the presence of the virus contributed little to the reduction in PH, HI, and DMC across the... |

| The purpose of this course is to train and familiarise people, who are going to build, have just built or are about to modernise a purification plant, in the latest technology available to the industry and also to train people so that they can effectively run a depuration centre. ln general the course aims to : - Give participants practical experience of different systems prior to committing themselves to a particular system. - Enable participants to compare systems. - Provide a minimum training qualification to run an establishment which is essentially a facility to guarantee health and safety of products to the consumer. - Provide an overview from bacteria testing to plant lay out etc. The structure of the course is in modules, morning and... |

| Abstract Small ruminant lentiviruses (SRLV) have high genetic variability which results in different viral strains around the world. This create a challenge to design sensible primers for molecular diagnosis in different regions. This work proposes a protocol of duplex nested-PCR for the precise diagnosis of SRLV. The technique was designed and tested with the control strains CAEV Co and MVV 1514. Then, field strains were submitted to the same protocol of duplex nested-PCR. Blood samples of sheep and goats were tested with AGID and nested PCR with specific primers for pol, gag and LTR. The AGID results showed low detection capacity of positive animals, while the nested PCR demonstrated a greater capacity of virus detection. Results demonstrated that... |

| In this review, diagnostic techniques and viral agents involved in enteric diseases affecting turkeys are described. Data from field observations and laboratory researches have been reported in turkey flocks for over 70 years, and several viruses have been identified. After a period of 30 years of inoculation experiments and neutralization studies, adequate visualization of the viruses was achieved using electronic microscopy. During the following years, several studies were then conducted to isolate and classify those viruses using cell-culture, embryo-propagation, serological tests, genome electropherotyping by polyacrylamide gel electrophoresis of double-stranded RNA viruses, and recently, nucleic acid studies. Thus, since the 1990s, the nucleic-acid... |
