Introduction and purpose
 The microbiota plays an important role in human metabolism, immune system, development of many chronic diseases, cancers, infectious diseases. aim the study is to present gut viral infections, including HBV, Herpesviridae, HIV, SARS-CoV-2. newest publications from last 5 years available on PubMed database were taken into account.

Infectious bovine rhinotracheitis (IBR) is a group of the respiratory disease multifaceted pathogens and key cattle, leading to significant economic losses dairy industry globally. The causative agent IBR Bovine herpesvirus type-1 (BoHV-1), which member genus Varicellovirus in Alphaherpesvirinae subfamily, belongs family Herpesviridae, order Herpesvirales. BoHV-1 can be categorized into three s...

In herpesvirus infections, the virus persists for life but is contained through T-cell-mediated immune surveillance. How this immune surveillance operates is poorly understood. Recent studies of other persistent infections have indicated that virus persistence is associated with functional deficits in the CD8(+) T-cell response. To test whether this is the case in a herpesvirus infection, we us...

Examination of sera from blood donors, from patients attending a special treatment clinic, a family planning clinic, and an antenatal clinic showed that the prevalence of herpes virus hominis type 2 antibodies among the adult population in Ibadan is similar to that in other parts of the world. The possibility of non-venereal transmission of herpes virus infection was confirmed by the finding th...

Herpes simplex virus and varicella-zoster virus cause dermatitis, blepharoconjunctivitis, keratitis, uveitis, glaucoma, and retinitis. These conditions are encountered frequently by the ophthalmologist in clinical practice. It should not be overlooked that herpesviruses can also produce an extraordinary variety of neuroophthalmological signs and symptoms. What follows is an overview of the most...

Aging in humans is associated with increased infections and the reduced proliferative capacity of T cells, part of the more global phenomenon termed immune senescence. The etiology of immune senescence is unknown but the accumulation of virus-specific memory T cells may be a contributory factor. We have examined CD8 T cell responses to two persistent herpesvirus infections, CMV and EBV, and to ...

Cellular chemotaxis is important to tissue homeostasis and proper development. Human herpesvirus species influence cellular chemotaxis by regulating cellular chemokines and chemokine receptors. Herpesviruses also express various viral chemokines and chemokine receptors during infection. These changes to chemokine concentrations and receptor availability assist in the pathogenesis of herpesvirus...

Herpesvirus outbreaks are common in natural animal populations, but little is known about factors that favour the infection and its consequences for the organism. In this study, we examined the pathophysiological consequences of a disease probably attributable to herpesvirus infection for several markers of immune function, corticosterone, telomere length and inflammation. In addition, we asses...

Varicella-zoster virus causes two distinct clinical diseases. Primary infection causes varicella or chickenpox in children and reactivation of infection causes herpes zoster (shingles) mostly among the elderly. The virus is a member of the herpesvirus family, restricted in its infective range to humans. Although chickenpox and shingles have been recognised for centuries, changes in population d...
