A new RT-PCR test has been developed to diagnose Chronic bee paralysis virus (CBPV) that is able to detect genetically variable viral isolates. In fact, up to 8.7% divergence between partial nucleotide sequences from viral isolates from French honey bees was highlighted in a preliminary variability study. The previously-described RT-PCR was unable to detect all these viral isolates and RT-PCR diagnosis needed improvement. The new RT-PCR test can detect up to 40% more CBPV isolates.

The COVID-19 outbreak was an important turning point in the development of a new generation of biosensing technologies. The synergistic combination of an immunochromatographic test (lateral flow immunoassays, LFIA) and signal transducers provides enhanced sensitivity and the ability to quantify in the rapid tests. This is possible due to the variety of nanoparticles that can be used as reporter labels.

Porcine epidemic diarrhea virus (PEDV) has caused significant harm to the global pig industry since its discovery. In this study, a highly pathogenic strain of GIIa PEDV CH/HBXT/2018, isolated previously, was continuously passaged in Vero cells up to passage (P)240, resulting in a completely attenuated virus. The proliferation characteristics of different passages of the strain in Vero cells, pathogenicity in newborn piglets, and mutations in S gene sequence indicated that as the passage number increased, the replication efficiency of PEDV in Vero cells gradually improved, with a more pronounced cytopathic effect.

Domestic animals can share viral pathogens with humans, acting mainly as a bridge host. The genus hosts important zoonotic species that have emerged in urban areas worldwide. Nevertheless, the role of companion animals, such as dogs and cats, in the circulation of orthopoxviruses in urban areas remains poorly understood.
