Human Virome

Human Virome

The human body harbors a vast and diverse viral community known as the human virome. The virome includes bacteriophages that infect bacteria, and eukaryotic viruses that infect human cells. Transient dietary and environmental viruses also contribute to this dynamic ecosystem. Estimates suggest the human body may contain on the order of 10¹³ viral particles, though abundance varies widely by body site and detection method.Comprehensive characterization of the virome has become possible only with...

Viral Recombination

Viral Recombination

Cells are sometimes infected by more than one virus at once. When two viruses disassemble to expose their genomes for replication in the same cell, similar regions of their genomes can pair together and exchange sequences in a process called recombination. Alternatively, viruses with segmented genomes can swap segments in a process called reassortment.

Hepatitis

Hepatitis

Hepatitis is an inflammatory condition of the liver most commonly caused by hepatotropic viruses (A–E), though non-infectious causes such as alcohol and drugs also exist.Hepatitis AHepatitis A virus (HAV) is a non-enveloped RNA virus of the Picornaviridae family. It is primarily transmitted via the fecal-oral route, typically through ingestion of contaminated food or water. After ingestion, HAV enters the bloodstream through the oropharynx or intestinal epithelium and reaches the liver. The...

Cytomegalovirus Disease

Cytomegalovirus Disease

Cytomegalovirus (CMV) disease is caused by human cytomegalovirus, a double-stranded DNA virus of the Herpesviridae family. While primary CMV infection is often asymptomatic in immunocompetent individuals, the virus can cause severe disease in neonates and immunocompromised patients. CMV is the most common cause of congenital viral infection in the United States, and a major pathogen in solid organ and hematopoietic stem cell transplant recipients.CMV is transmitted via bodily fluids, sexual...

Summary

This summary is machine-generated.

Tembusu virus (TMUV) infection is emerging in humans, with high rates of antibodies and RNA found in Chinese duck workers. This zoonotic virus, linked to severe egg drop in ducks, may be underdiagnosed.

Background:

Tembusu virus (TMUV) has been previously identified in domestic poultry and wild birds in China.
TMUV is known to cause significant economic losses in the duck industry due to severe egg drop.

Purpose of the Study:

To investigate the potential zoonotic transmission of TMUV to humans.
To confirm the emergence of TMUV infection in duck industry workers in Shandong, China.

Main Methods:

Sera from 132 duck industry workers were tested for TMUV antibodies.
Oral swabs were analyzed for the presence of TMUV RNA.
Partial NS3 protein gene sequences were analyzed for genetic relatedness.

Main Results:

A high prevalence of TMUV antibodies (71.9%) was detected in the serum samples.
TMUV RNA was detected in 47.7% of oral swab samples.
Sequenced viral strains showed over 99.5% identity to duck TMUV strains.

Conclusions:

These findings indicate a significant circulation of TMUV among duck industry workers.
TMUV poses a potential zoonotic risk that may be underestimated in China.
Further research is warranted to understand the full scope of TMUV zoonosis.
