Detecção e classificação molecular de Chlamydophila psittaci em amostras fecais de aves assintomáticas

Chlamydophila psittaci is a bacterium that causes respiratory or systemic disease in birds and humans. Owing to the risk of transmission from asymptomatic birds to humans, the objective of this study was to detect the presence of Chlamydophila spp. in asymptomatic birds. Four hundred and three fecal samples or cloacal swabs were collected from domestic, wild or exotic birds. The 403 samples were examined by real time PCR specific for the 16S subunit of rRNA gene using SsoFastEvaGreen®SupermixTM (Bio-Rad) and melting curve analysis. Hemi-nested PCR specific for the OMP-A gene, accomplished in real-time PCR positive samples, was followed by sequencing of the amplified fragments to determine the genotype of C. psittaci. Real-time PCR was positive in 17 (4.21%) samples. Hemi-nested PCR revealed positivity in two samples previously positive by real-time PCR. Sequencing of the fragment amplified by hemi-nested PCR allowed for the identification of genotype A of C. psittaci in one sample. The results of this experiment show that the real-time PCR targeting the 16S rRNA gene followed by melting curve analysis can be used for diagnosis of Chlamydophila sp. in fecal samples of asymptomatic birds. The classification of the Chlamydophila species and the genotype of C. psittaci must be accomplished by PCR targeting the ompA gene and sequencing of the amplified fragments.

Influence of the sample area in the variability of losses in the mechanical harvesting of soybeans

The mechanical harvesting is an important stage in the production process of soybeans and, in this process; the loss of a significant number of grains is common. Despite the existence of mechanisms to monitor these losses, it is still essential to use sampling methods to quantify them. Assuming that the size of the sample area affects the reliability and variability between samples in quantifying losses, this paper aimed to analyze the variability and feasibility of using different sizes of sample area (1, 2 and 3 m²) in quantifying losses in the mechanical harvesting of soybeans. Were sampled 36 sites and the cutting losses, losses by other mechanisms of the combine and total losses were evaluated, as well as the water content in seeds, straw distribution and crop productivity. Data were subjected to statistical analysis (descriptive statistics and analysis of variance) and Statistical Control Process (SCP). The coefficients of variation were similar for the three frames available. Combine losses showed stable behavior, whereas cutting losses and total losses showed unstable behavior. The frame size did not affect the quantification and variability of losses in the mechanical harvesting of soybeans, thus a frame of 1 m² can be used for determining losses.

Use of Internet and online interactions in a Brazilian sample

This work focused on the use of internet and online interactions and was based on data collected from a sample of Brazilian college students (64 people) who were asked to answer the Face-to-Face and Online Interaction Survey. The outcomes are analyzed in this paper and from them it is possible to observe patterns on internet interaction. It was also possible to conclude that the sample frequently uses the Internet, its online interactions and that this kind of interaction is used as a complement to face-to-face communication.
