Bocaparvoviruses

Bocaparvoviruses are a genus of small, non-enveloped, single-stranded DNA viruses belonging to the family Parvoviridae. These viruses are characterized by their icosahedral capsid and their genome, which is approximately 4 to 5 kilobases in length. Bocaparvoviruses are known to infect a wide range of hosts, including mammals, birds, and reptiles.

Historically, several bocaparvin species were initially considered to be non-pathogenic or to cause only mild symptoms. However, recent research has revealed that some bocaparvoviruses can be associated with significant disease. For example, human bocavirus (HBoV) has been linked to respiratory tract infections, particularly in children, and has also been implicated in gastroenteritis and other conditions. Other species, such as minute virus of canines (MVC) and parvovirus h-1 (H-1PV), are known to infect specific animal hosts and can cause various clinical signs.

The classification of bocaparvoviruses is based on genomic and serological criteria. The genus currently comprises several species, with ongoing research identifying new strains and potentially new species. Transmission routes can vary depending on the specific virus and host but often involve fecal-oral or respiratory routes. Diagnosis typically relies on molecular methods such as PCR, detecting viral DNA in clinical samples. While there are no specific antiviral treatments for most bocaparvovirus infections, supportive care is usually provided. The potential for some bocaparvoviruses to cause disease highlights the importance of continued surveillance and research into their pathogenesis and epidemiology.
