background torque teno virus (ttv) belongs to the circoviridae family and was separated from japanese patients with elevated levels of serum alanine transferase for the first time. following this, extensive studies have been carried out around the world. objectives the present study was designed to investigate and determine the frequency of ttv genotypes in patients with chronic hepatitis b and...
In this study, we analyzed viral metagenomes (viromes) in the sedimentary habitats of three geographically and geologically distinct (hado)pelagic environments in the northwest Pacific; the Izu-Ogasawara Trench (water depth = 9,760 m) (OG), the Challenger Deep in the Mariana Trench (10,325 m) (MA), and the forearc basin off the Shimokita Peninsula (1,181 m) (SH). Virus abundance ranged from 10(...
Swine are an important source of proteins worldwide but are subject to frequent viral outbreaks and numerous infections capable of infecting humans. Modern farming conditions may also increase viral transmission and potential zoonotic spread. We describe here the metagenomics-derived virome in the feces of 24 healthy and 12 diarrheic piglets on a high-density farm. An average of 4.2 different m...
Improvements and widespread use of nucleic acid amplification and sequencing methods have led to the recognition of new virus diversity in various domestic animals, including pigs. In this study we utilized either virus species specific or broadly reactive PCR assays to describe the occurrence and genetic diversity of selected DNA viruses belonging to families Adenoviridae, Circoviridae, Anello...
BACKGROUND Chicken anemia virus (CAV), the causative agent chicken anemia, is the only member of the genus Gyrovirus of the Circoviridae family. CAV is an immune suppressive virus and causes anemia, lymph organ atrophy and immunodeficiency. The production and biochemical characterization of VP1 protein and its use in a subunit vaccine or as part of a diagnostic kit would be useful to CAV infect...
Psittacine Beak and Feather Disease (PBFD) is a contagious, fatal viral disease that affects the beak, feathers, and immune system of wild and captive old and New World Psittacine. PBFD is characterized by feather abnormalities, beak and claw deformities and eventually dying as a result of immunosuppressant. The disease is caused by member of the genus circovirus in the family Circoviridae. The...
Species within the Neoromicia bat genus are abundant and widely distributed in Africa. It is common for these insectivorous bats to roost in anthropogenic structures in urban regions. Additionally, Neoromicia capensis have previously been identified as potential hosts for Middle East respiratory syndrome (MERS)-related coronaviruses. This study aimed to ascertain the gastrointestinal virome of ...
سرطان از مهمترین عوامل مرگ انسان به شمار می آید. بسیاری از درمان های شیمیایی و پرتودرمانی فاقد اختصاصیت کافی برروی سلول های سرطانی بوده و دارای اثرات جانبی بر روی سایر سلولها نیز می باشند. پیشرفت های شگرف علم امروز در درمان سرطان باعث افزایش امید به درمان سرطان های مقاوم و ناعلاج انسان شده است. با تکیه بر درک تازه انسان از نحوه پاتوژنز ملکولی سرطان ها می توان دارهای جدید نظیر نانوبادی ها و آنتی...
