“…According to Alencar et al (2016), symptoms depend on the virus isolate, plant species and environment; however, the majority of susceptible hosts present a severe systemic mosaic, with leaf and fruit deformation. The symptoms can also vary if the host plant is concomitantly infected by different viruses (Barbosa et al, 2016;Silva et al, 2016).…”

Zucchini (Cucurbita pepo L.) is a horticultural plant species of great socioeconomic value in tropical countries such as Colombia and Brazil. The production of zucchini is qualitatively and quantitatively affected by many diseases, especially viruses belonging to the Potyvirus (Zucchini yellow mosaic virus - ZYMV) and Comovirus (Squash mosaic virus - SqMV) groups. The primary strategy to reduce the spread of potentially damaging plant viruses is the development of genotypes with genetic tolerance; however, there are not many zucchini genotypes with multiple tolerance. Therefore, this study evaluated 66 zucchini genotypes to find sources of tolerance to the ZYMV and SqMV viruses. This experiment was conducted in a completely randomized design using genotypes from the germplasm bank of the Federal University of Uberlândia, including the genotypes: Emanuela (common commercial genotype) ‘Tronco Caserta’ (susceptible genotype) and PX 13067051 (resistant genotype). Leaf extracts containing viral particles were used as inoculant, and the distribution of grades of tolerance was recorded at the seedling stage. The lineages UFU-C×UFU-A#18#3;1, UFU-C×UFU-F#19#11;3, UFU-F#4#9;1, and UFU-D×UFU-F#7#21;1 and the Emanuela cultivar are alternatives for the production of new zucchini genotypes or hybrids with tolerance to the viruses ZYMV and SqMV. More severe symptoms were observed, as well as a larger number of susceptible genotypes for the ZYMV virus, indicating that this virus has great potential for causing damage and losses to zucchini crops.

“…Plant viruses are responsible for decreasing the quantity and quality of crop yield, leading to significant economic losses. Squash mosaic virus (SqMV) is an example of a phytovirus (family Secoviridae genus Comovirus ) that infects melons and a diversity of plants of the family Cucurbitaceae [ 1 , 2 ].…”

“…SqMV is spread mainly by infected seeds, and can be transmitted by chrysomelid beetles, including Acalymma trivittata and Diabrotica spp. [ 1 , 2 ]. Symptoms and severity of the plant disease vary, depending on many factors, including the strain of the virus, the species and/or variety of plant, and the population of vectors [ 10 ].…”

New Variants of Squash Mosaic Viruses Detected in Human Fecal Samples

Squash mosaic virus (SqMV) is a phytovirus that infects great diversity of plants worldwide. In Brazil, the SqMV has been identified in the states of Ceará, Maranhão, Piauí, Rio Grande do Norte, and Tocantins. The presence of non-pathogenic viruses in animals, such as phytoviruses, may not be completely risk-free. Similarities in gene repertories between these viruses and viruses that affect animal species have been reported. The present study describes the fully sequenced genomes of SqMV found in human feces, collected in Tocantins, and analyzes the viral profile by metagenomics in the context of diarrhea symptomatology. The complete SqMV genome was obtained in 39 of 253 analyzed samples (15.5%); 97.4% of them belonged to children under 5 years old. There was no evidence that the observed symptoms were related to the presence of SqMV. Of the different virus species detected in these fecal samples, at least 4 (rotavirus, sapovirus, norovirus, parechovirus) are widely known to cause gastrointestinal symptoms. The presence of SqMV nucleic acid in fecal samples is likely due to recent dietary consumption and it is not evidence of viral replication in the human intestinal cells. Identifying the presence of SqMV in human feces and characterization of its genome is a relevant precursor to determining whether and how plant viruses interact with host cells or microorganisms in the human gastrointestinal tract.

“…Preeclampsia can also cause serious perinatal complications, such as fetal distress, intrauterine growth restriction, and even lead to sudden fetal death and premature delivery. Preeclampsia is not only a serious threat to maternal and child health, but also one of the main causes of maternal and perinatal illness and death [4][5].…”

Pre-eclampsia is extremely harmful to mothers and infants. It often leads to a series of poor prognosis such as fetal distress, fetal growth restriction, placental abruption, premature delivery, acute renal failure and so on. At present, there is no effective method for predicting preeclampsia at home and abroad, so further research is needed. The purpose of this article is to analyze the relationship between serological indicators and preeclampsia by observing and analyzing the serological indicators of clinical testing, to understand the role of clinical testing serological indicators in the prediction of preeclampsia, and to the pre-eclampsia clinical testing serological indicators before and after In contrast, study the relationship between clinical test serological indicators and preeclampsia. Using the method of this article, through the analysis of experimental data, we understand the role of clinical test serological indicators in the prediction of preeclampsia, and find that clinical test serological indicators play an important role. Through the combination of theory and experimental data, we analyze the clinical test serology the predictive effect of the indicator in preeclampsia reached 84.6%. The research results show that HCG value can be used as one of the factors for predicting preeclampsia. According to these indicators, effective prediction of preeclampsia is provided, which provides a real basis for clinical prediction of preeclampsia, and finds a breakthrough from the prediction of PE to reduce the incidence of PE and improve the prognosis of pregnant women and fetuses of PE.
