This study investigatedPerkinsusspp. infectingCrassostrea rhizophoraefrom the Jaguaribe River estuary,Ceará, Brazil. Fragments of gills and rectum of the oysters (n = 150) were incubated in Ray’s fluid thiogly-collate medium (RFTM). GenusPerkinsus-specific PerkITS85/750 PCR assays were performed and theiramplicons were sequenced by the Sanger method. The RFTM assays confirmedPerkinsusspp. Thesequencing of the a...
This work aimed to perform the genetic manipulation of the native B. cereus #25 strain and to evaluate the colonization in the intestinal tract of Litopenaeus vannamei. The expression of the GFPmut1, absence of amylase activity, and growth in spectinomycin plates confirmed the transformation of the strain (BC25GM). In the shrimp bioassay, its addiction in the feed showed non-difference for water quality, growth...
This work investigated the occurrence of Perkinsus sp. in clam Anomalocardia brasiliana, oyster Crassostrea sp. and mussel Mytella falcata from the Jaguaribe River estuary, northeastern Brazil. The collection of clam (N = 300), oysters (N = 300) and mussels (N = 300) were carried out in the estuary of the Jaguaribe River, Ceará, in March and April (rainy season) and October (dry season) in 2017. The mollusks we...

Viruses are the pathologies that cause greater impact in the shrimp farming and consequential biggest economic damages registered in the sector. Despite Infectious hypodermal and hematopoietic necrosis virus (IHHNV) is considered a pathogen of low impact in Litopenaeus vannamei species, it can bring some negative economic implications for the shrimp industry, as reduction of growth rates and low productivity. A...
Assim como em qualquer atividade zootécnica, a carcinicultura brasileira começa a encontrar sérios obstáculos em decorrência do acometimento de algumas enfermidades que chegam a comprometer o seu desenvolvimento em potencial. As viroses são, invariavelmente, as que causam maior impacto e por isso maiores prejuízos econômicos registrados no setor. Dentre as doenças virais que têm provocado perdas consideráveis n...
