TT Virus Infection in Gibbons.

NOTE Virology TT Virus Infection in Gibbons

TT virus (TTV) is not only an infectious agent of worldwide distribution but has also been demonstrated in various non-human primates in addition to humans. In the present study, we subjected the sera of 67 gibbons to PCR and nucleotide sequencing, with subsequent phylogenetic analysis to determine the nature of the relationship between TTV found in humans and non-human primates. We discovered ...

tt virus infection in transfusion-dependent thalassemia patients

Prevalence and prognostic significance of infection with TT virus in patients infected with human immunodeficiency virus.

No clear association between human disease and TT virus (TTV) has been documented. A possible pathogenic role of TTV was investigated in patients infected with human immunodeficiency virus (HIV). TTV serum concentrations were estimated in 185 HIV-infected patients by dilution polymerase chain reaction. Of these, 149 (76%) were TTV-positive, compared with 18 (7%) of 252 Danish blood donors (P<. ...

TT virus in bone marrow transplant recipients.

TT virus (TTV) is a newly discovered transfusion-transmissible DNA virus, which may cause posttransfusion hepatitis. The virus was detected in 12% of Japanese blood donors. The aim of the study is to investigate the prevalence and clinical influence of TTV in bone marrow transplant (BMT) recipients. Sera from 25 BMT recipients obtained 6 to 12 weeks after the transplant were examined for TTV-DN...

Gibbons

What is a gibbon? Gibbons (Hylobatidae) are small arboreal apes that are predominantly found in tropical and sub-tropical forests of South East Asia, South China, Bangladesh and North-East India. True brachiators — animals that swing from tree to tree — these apes are often described as ‘acrobats of the forest’, leaping up to 8 metres between branches and reaching speeds of approximately 56 kil...
