Ungulate bocaparvovirus 4 and rodent bocavirus are different genotypes of the same species of virus.

Bocaviruses are associated with many human infectious diseases, such as respiratory tract infections, gastroenteritis, and hepatitis. Rats are known to be reservoirs of bocaviruses, including rodent bocavirus and rat bocavirus. Recently, ungulate bocaparvovirus 4, a known porcine bocavirus, has also been found in rats.

Effectiveness of Inactivated COVID-19 Vaccines Against Illness Caused by the B.1.617.2 (Delta) Variant During an Outbreak in Guangdong, China : A Cohort Study.

Background: Real-world evidence on inactivated COVID-19 vaccines against the highly transmissible B.1.617.

Detection and Genetic Characterization of Seoul Virus in Liver Tissue Samples From and in Urban Areas of Southern China.

Rodents are important hosts of hantaviruses, and lungs and kidneys are known to be the preferred organs of these viruses. Recently, hantaviruses were detected in liver samples from wild rodents in Hungary and the United States, and feeder rats in the Netherlands. However, few studies have detected hantaviruses in the liver of rats from China.

Composition of gut and oropharynx bacterial communities in Rattus norvegicus and Suncus murinus in China.

Background: Rattus norvegicus and Suncus murinus are important reservoirs of zoonotic bacterial diseases. An understanding of the composition of gut and oropharynx bacteria in these animals is important for monitoring and preventing such diseases. We therefore examined gut and oropharynx bacterial composition in these animals in China.

Risk factors associated with COVID-19 infection: a retrospective cohort study based on contacts tracing.

This study aimed to estimate the attack rates, and identify the risk factors of COVID-19 infection. Based on a retrospective cohort study, we investigated 11,580 contacts of COVID-19 cases in Guangdong Province from 10 January to 15 March 2020. All contacts were tested by RT-PCR to detect their infection of SARS-COV-2.

Comparisons of microbiological characteristics and antibiotic resistance of Klebsiella pneumoniae isolates from urban rodents, shrews, and healthy people.

Background: The comparisons of molecular characterization and antibiotic resistance of Klebsiella pneumoniae (KP) isolates from humans and other animal hosts are not well studied. Our goal was to compare the molecular epidemiology of KP strains that were isolated from urban rodents, shrews, and healthy people.

Results: K.

Methicillin-resistant Staphylococcus aureus among urban rodents, house shrews, and patients in Guangzhou, Southern China.

Background: The transmission of methicillin-resistant Staphylococcus aureus (MRSA) between humans and animals has been identified in a number of countries. In this study, MRSA in urban rodents and shrews in a community was investigated. Further, comparisons of MRSA isolates from rodents, shrews, and humans were conducted to evaluate the relationships of these isolates from different origins.

The prevalence and genomic characteristics of hepatitis E virus in murine rodents and house shrews from several regions in China.

Background: Urban rodents and house shrews are closely correlated in terms of location with humans and can transmit many pathogens to them. Hepatitis E has been confirmed to be a zoonotic disease. However, the zoonotic potential of rat HEV is still unclear.

The risk of human papillomavirus infection for male fertility abnormality: a meta-analysis.

Human papillomavirus (HPV) is the most common sexually transmitted virus in males and females worldwide; yet its impact upon male fertility remains unclear. The objective of this study was to evaluate the potential impact of HPV infection in semen on male fertility abnormality. A systematic literature search was performed in PubMed, Medline, Embase, Web of Science, and the Cochrane Library database for relevant publications up to May 6, 2017.

Optical coherence tomography for the diagnosis of malignant skin tumors: a meta-analysis.

Optical coherence tomography (OCT) is an emergent imaging tool used for noninvasive diagnosis of skin diseases. The present meta-analysis was carried out to assess the accuracy of OCT for the diagnosis of skin cancer. We conducted a systematic literature search though EMBASE, Medline, PubMed, the Cochrane Library, and Web of Science database for relevant articles published up to June 6, 2017.

Viral metagenomics of six bat species in close contact with humans in southern China.

Accumulating studies have shown that bats could harbor various important pathogenic viruses that could be transmitted to humans and other animals. Extensive metagenomic studies of different organs/tissues from bats have revealed a large number of novel or divergent viruses. To elucidate viral diversity and epidemiological and phylogenetic characteristics, six pooled fecal samples from bats were generated (based on bat species and geographic regions characteristic for virome analysis).
