Summary: This study analyzed the seroprevalence and antibody levels of BKPyV and JCPyV in 327 pregnant women and their 132 spouses in Finland. The results showed that BKPyV and JCPyV infections were common in married couples, with slightly higher prevalence in women and stable antibody levels.

Summary: A study has identified widespread genomic rearrangements in clinical urine specimens of BK and JC polyomaviruses, indicating the presence of defective viral genomes (DVGs) in DNA viruses in clinical settings. These DVGs are more commonly found in samples with higher viral loads and persist during infection without reaching clonality in the chronically infected host.

Summary: BK (BKPyV) and JC (JCPyV) polyomaviruses are common in infants, with high correlation of antibody levels between mother-infant pairs. The correlation differs between father-child pairs and may be related to predisposition to allergies.

Summary: This paper presents a portable integrated digital PCR system for quantitative analysis of BK virus directly from raw urine samples using a self-partitioning SlipChip microfluidic device. The system eliminates the need for complex nucleic acid extraction and purification, providing quick and accurate viral load analysis with a simple workflow. With a compact and lightweight design, the system is suitable for point-of-care testing environments.

Summary: Mutations in the BKPyV capsid accumulate in kidney transplant recipients, and are associated with neutralization escape. The mutations are mainly caused by cytosine deamination by APOBEC3A/B enzymes.

Summary: BKPyV and JCPyV were detected in a small percentage of bladder cancer samples in South of Iran. Although these viruses were present in some bladder cancer biopsy specimens, they are unlikely to be the major causative factors in bladder carcinogenesis in this region. Environmental risk factors and genetic backgrounds may play a more prominent role in the development of bladder cancer in South of Iran.

Summary: The study focused on fecal source tracking in low-income households, investigating the impact of shared sanitation facility improvements on fecal contamination. Results showed a reduction in Escherichia coli gene concentrations in soil, but no significant change in the prevalence of human FST markers.

Summary: Pesticide use poses potential hazards to wild birds. Noninvasive sampling methods and data on a wide variety of agrochemicals are needed to determine pesticide exposure of living wild birds. This study found residues of multiple pesticides in the feces of Eurasian skylarks that forage in winter cereal crops, with potential effects on their body condition.

Summary: Squash mosaic virus (SqMV) has been identified in various plants globally, including in multiple states in Brazil. The study found SqMV in human feces collected in Tocantins, with no evidence of related symptoms. Analysis showed a presence of multiple viruses in fecal samples from diarrhea patients, with at least 4 known to cause gastrointestinal symptoms.

Summary: This study described a new quantitative TaqMan(R) probe-based real-time PCR assay for the quantification of Paenibacillus larvae spores in powdered sugar samples collected from hives. The results showed that this method had a higher detection rate and closer concordance with the clinical-epidemiological status of the hives compared to culture method.
