Screening of apple samples using a high-throughput sequencing (HTS) approach led to the discovery of a novel virus, tentatively named "Malus domestica virus A" (MdoVA). Its genomic organisation and phylogenetic relationship showed relatedness to viruses of the genus Velarivirus in the family Closteroviridae. It is not clear whether MdoVA has any impact on its host, as the analysed apple tree contained other viruses and a viroid.

Objective: To understand the prevalence, genetic diversity, and potential pathogenicity of adenoviruses present in pigeon and turtledove populations.
Methods: Nested PCR and Sanger sequencing methods were used to identify the genotype and percentage of various adenoviruses in the feces of pigeon (Columba) and turtledove (Streptopelia) populations. In Beijing, China, a total of 194 fresh feces samples from meat-use pigeons (C livia domestica), homing pigeons (C livia domestica), wild pigeons (C livia domestica), and turtledoves (S decaocto and S chinensis) were collected using noninvasive sampling collection techniques.

The Zika virus (ZIKV) epidemic elicited a rapid commitment to the development of animal models for ZIKV research. Non-human primates (NHPs) and mice have made significant contributions to this research, but NHPs are expensive, have a long gestation period, and are available only in small numbers; non-genetically modified mice are resistant to infection. To address these deficiencies, we have established the laboratory opossum, , as a small animal model that complements the mouse and monkey models.

Article Synopsis
- The study investigates the genotype-by-genotype (GxG) interactions between the obligate fungal pathogen Entomophthora muscae and various dipteran fly hosts, highlighting how both the fungal and host genotypes influence infection dynamics.
- Researchers collected new isolates of E. muscae from Drosophila species and discovered that these isolates formed a distinct lineage, which was confirmed by phylogenetic analysis indicating geographical variation in host-specificity.
- Experimental results showed that while house flies displayed a high susceptibility to E. muscae with 99% mortality, different Drosophila species had lower mortality rates, thus demonstrating the impact of host genotype on pathogen virulence.

salivary gland hypertrophy virus (MdSGHV) affects house flies by enlarging salivary glands, impeding ovary development in females, and mating behavior in both males and females. It is not known if this virus impacts the quantity of saliva produced by house flies. This study aimed to establish baseline saliva quantities in healthy across sexes and ages and examine how MdSGHV infection influences saliva output in 5-day-old males.

Plant richness and microbiota have been associated with plant health; hardly any studies have investigated how plant taxa differs in microbiota in the context of human health. We investigated the microbial differences in buds of 83 woody plant taxa used in urban green spaces in hemiboreal climate, using 16S rRNA and whole metagenome shotgun sequencing. Bud microbial community was the richest in Cotoneaster Nanshan and C.
