Summary: The major histocompatibility complex (MHC) is crucial for the vertebrate immune system, but accurately characterizing MHC genetic diversity in non-model species is technically challenging due to gene duplication and diversification. A new long-read based MHC typing method has been developed to address these challenges and provide better solutions for high accuracy MHC typing in research. This approach allows for population-scale MHC typing in various species, revealing new insights into genetic diversity.

Summary: Meiotic recombination ensures chromosome segregation and promotes allele shuffling. RecombineX is a computational framework that automates the analysis of tetrad sequencing data, allowing for marker identification, genotyping, and recombination profiling. It can analyze data based on reference genomes or parental assemblies, and includes features for copy number variation profiling and missing genotype inference. RecombineX also includes a simulation module for hypothesis testing. It has been demonstrated to be accurate and robust for organisms with small and large genomes.

Summary: The use of molecular markers is crucial in various fields of molecular genetics, such as gene identification, plant breeding, and genetic characterization. Transposable elements, particularly retrotransposons, are widely used as molecular markers due to their presence in eukaryotic genomes and ability to integrate into dispersed chromosomal locations. The ongoing development of molecular marker technologies is closely linked to high-throughput genotype sequencing platforms, making this research highly significant.

Summary: In recent years, artificial intelligence (AI) has revolutionized chemical synthesis, but the lack of suitable representation methods for chemical reactions and scarcity of reaction data hinder the wider application of AI in reaction prediction. This study introduces a novel reaction representation called GraphRXN, which uses a universal graph-based neural network framework to encode chemical reactions directly from two-dimensional reaction structures. The GraphRXN model demonstrates comparable or superior performance to other baseline models when evaluated on three publicly available chemical reaction datasets. Wet-lab experiments were conducted to generate reaction data for further evaluation of the effectiveness of GraphRXN. The model achieved decent accuracy (R-2 of 0.712) when built on high-throughput experimentation data, suggesting its potential for deployment in an integrated workflow combining robotics and AI technologies for forward reaction prediction.

Summary: In this study, the current status of the modern Italian gene pool was described. The results show that some native Italian breeds preserve distinct gene pools, potentially due to adaptation to different geographical contexts. However, comparisons with international breeds reveal strong gene flow from renowned breeds into several Italian breeds, likely due to historical introgression. Some breeds also show unique characteristics based on their breeding history. Lastly, certain breeds exist more for cultural, traditional, and geographical reasons rather than genetic distinctiveness.

Summary: Human immunodeficiency virus (HIV) can develop resistance to all antiretroviral drugs, but multidrug resistance is rare. The accumulation of resistance mutations follows a predetermined order rather than being acquired randomly and simultaneously. Understanding this order can help elucidate the mechanisms of multidrug resistance.

Summary: Wastewater surveillance is crucial in managing the global COVID-19 pandemic, serving as an early warning system for outbreaks and a tool to track the circulation of specific variants. This study used various wastewater collection points in Leuven to investigate the application of wastewater surveillance. Wastewater samples were collected and analyzed using RT-qPCR to quantify SARS-CoV-2 RNA, and specific mutations were detected to identify circulating variants. The study found that wastewater SARS-CoV-2 concentration preceded peaks in positive cases and detected the presence of different variants simultaneously during the transition period. Wastewater-based surveillance is a valuable tool for monitoring virus circulation and variants in larger populations.

Summary: This study aimed to characterize the longitudinal plasma virome dynamics in chronic hepatitis B virus (HBV) infected patients. The virome was primarily composed of members of the Anello-, Flavi-, and Hepadnaviridae (HBV) families. The study found no correlation between virome structure and dynamics with the different stages of chronic HBV infection or antiviral therapy. The analysis of viruses observed in multiple timepoints revealed the presence of a dynamic community.

Summary: The largest outbreak of sylvatic yellow fever virus (YFV) in Brazil between 2016-2018 was reported, and entomo-virological surveillance was considered important for monitoring YFV. Mosquitoes were collected from six Brazilian states and tested for YFV using RT-qPCR. YFV infection was detected in various mosquito species, including Ae. albopictus, indicating the potential for urban YFV re-emergence. The study highlights the need to strengthen YFV surveillance, vaccination coverage, and vector control measures in Brazil.

Summary: This study aimed to investigate the value of performing a biopsy at the time of BKPyV-DNAemia in distinguishing presumptive and proven PyVAN. The results showed that plasma viral load had good predictive value for SV40 positivity, while the dichotomy of SV40 immunohistochemistry did not predict viral clearance. Therefore, the distinction between presumptive and proven PyVAN based on SV40 immunohistochemistry has limited clinical value.

Summary: Monkeypox is a viral zoonosis with circulation in animals and humans in some African countries. Despite the long-known identification of monkeypox virus (MPXV) as a human pathogen, the availability of accurate diagnostic assays and comparative performance studies remains limited. In this study, we developed a real-time PCR test and evaluated its performance against a commercial detection assay. Our results demonstrate the validity and accuracy of the developed test for confirming MPXV infection.

Summary: Since its discovery in early 1916, dengue fever has caused extensive urban outbreaks in Brazil, posing a serious threat to public health. A genomic surveillance training program was conducted in collaboration with local health authorities, resulting in the generation of 177 DENV genome sequences collected during a period of high dengue fever cases. The study identified the co-circulation of different dengue serotypes and diverse viral lineages, indicating multiple introduction events of viral strains in the region. The findings highlight the complex and changing dynamics of DENV transmission and emphasize the value of ongoing surveillance activities in informing public health actions.

Summary: Despite the use of new treatments, antimicrobial resistance is still increasing, calling for novel strategies. Bacteriophages have the potential to control bacterial pathogens like Salmonella. A Salmonella phage, Wara, was isolated from water samples in the Subae River Basin in Brazil. Its genome was sequenced using Oxford Nanopore Technologies and Illumina HiSeq, and assembly was carried out using Racon and Unicycler. Wara was found to be a member of the Tequintavirus genus and has therapeutic and biocontrol potential against Salmonella in healthcare and agriculture.
