The color is an important factor to distinguish the commercialized Amazon river prawns. The accumulation of pigments in the body can vary according to the prawn?s diet. In this work, ethanolic extracts of ?buriti? and annatto rich in pigments were obtained and tested comparatively with synthetic astaxanthin in the feeding of adults of Macrobrachium amazonicum, together with a control group without pigments and a newly captured wild group. Levels of body pigments were measured using UV reflective spectroscopy and external staining by colorimetry. Differences were observed in the accumulation of astaxan thin in body tissues, differences in saturation between genders and that annatto extract has greater stability in the feed after water immersion (P˂0.05). Further studies are recommended to verify the ideal dosage of natural pigments in relation to synthetic astaxanthin that benefits the productive development of prawns. |

Porcine parvovirus 4 (PPV4) is a DNA virus, and a member of the Parvoviridae family within the Bocavirus genera. It was detected recently in swine, but its epidemiology and pathology remain unclear. A TaqManbased real-time PCR (qPCR) targeting a conserved region of the ORF3 gene of PPV4 was developed. The qPCR detection limit was 9.5 × 101 DNA copies/L. There was no cross-reaction with porcine parvovirus, torque teno virus 1, torque teno virus 2, porcine circovirus type 1, porcine circovirus type 2, or with pseudorabies virus. Two hundred and seventy-two samples, including serum, semen, lungs, feces, ovarian follicular fluids, ovaries and uterus, were evaluated by qPCR and PPV4 was detected in 36 samples (13.2%). When compared with a conventional PCR (cPCR), the qPCR assay was 10 times more sensitive and the detection of PPV4 DNA in field samples was increased 2.5 times. Partial sequencing of PPV4 ORF3 gene, obtained from two pooled samples of uterus and ovaries, revealed a high nucleotide identity (98?99%) with a reference PPV4 sequence. The qPCR can be used as a fast and accurate assay for the detection and quantification of PPV4 in field samples and for epidemiological studies in swine herds. |
