The aim of this study was to evaluate the effect of culture media and stage of development in the osmotic ability of in vitro-fertilized bovine embryos and the expression of aquaporin 3 (Aqp3) and Na/K ATPase isoform 1 (ATPAse1) genes in embryos (i) with different ability to undergo rehydration and (ii) following vitrification. In experiment 1, in vitro fertilized presumptive zygotes were co-cultured in SOFaac or modified CR2aa medium and embryos at blastocyst and expanded blastocyst stages at day 7 post-insemination were exposed to NaCl hypertonic medium (900 mOsm) for 5 min following 120 min of culture in isotonic medium in order to evaluate dehydration and rehydration, respectively. No difference (P>0.05) on blastocyst rate was found between CR2aa and SOFaac medium but embryos co-cultured in SOFaac medium underwent greater (P<0.05) dehydration. Embryos at expanded blastocyst stage underwent greater dehydration but slower rehydration than embryos at blastocysts stage (P<0.05). In the experiment 2, the amount of Aqp3 and ATPase1 transcripts were quantified in blastocysts with high or low rehydration after exposure to hypertonic medium. No difference (P>0.05) on relative amount of transcripts was found in either genes. In the experiment 3, expanded blastocysts produced in a co-culture system were vitrified, warmed and then cultured for 72 h for analysis of embryo survival and amount of Aqp3 and ATPase1 transcripts. Lower (P<0.05) embryo survival rate was found for vitrified-warmed embryos (57.9%) than for their fresh counterparts (84.6%). There was no difference on expression of ATPase1 gene but lower (P<0.01) amount of Aqp3 transcripts was found in the vitrified-warmed embryos. In conclusion, embryo ability to undergo shrinkage and swelling is influenced by medium used in a co-culture system and by embryo stage. Rehydrating ability of embryos after exposure to NaCl hypertonic medium is not associated with variations on expression of Aqp3 and ATPase1 genes, but the vitrification can alter gene expression of in vitro-fertilized bovine embryos produced in a co-culture system.

The objective of this work was to select surviving breeders of Litopenaeus vannamei from white spot syndrome virus (WSSV) outbreak, adapted to local climatic conditions and negatively diagnosed for WSSV and infectious hypodermal and hematopoietic necrosis virus (IHHNV), and to evaluate if this strategy is a viable alternative for production in Santa Catarina, Brazil. A total of 800 males and 800 females were phenotypically selected in a farm pond. Nested-PCR analyses of 487 sexually mature females and 231 sexually mature males showed that 63% of the females and 55% of the males were infected with IHHNV. Animals free of IHHNV were tested for WSSV, and those considered double negative were used for breeding. The post-larvae produced were stocked in nine nursery tanks for analysis. From the 45 samples, with 50 post-larvae each, only two were positive for IHHNV and none for WSSV. Batches of larvae diagnosed free of virus by nested-PCR were sent to six farms. A comparative analysis was carried out in growth ponds, between local post-larvae and post-larvae from Northeast Brazil. Crabs (Chasmagnathus granulata), blue crabs (Callinectes sapidus), and sea hares (Aplysia brasiliana), which are possible vectors of these viruses, were also evaluated. The mean survival was 55% for local post-larvae against 23.4% for post-larvae from the Northeast. Sea hares showed prevalence of 50% and crabs of 67% of WSSV. |
