Alterations of B cell subpopulations have been described up to date as characterizing advanced stage of HIV-1 infection. However, whether such defects are relevant in subjects with a preserved number of CD4⁺ T cells (>350 cells/μL) is unclear. In a cross-sectional study, we investigated if signs of B cells exhaustion and impaired viral immune surveillance are present in a cohort of 43 asymptoma...
This work aimed to detect and study natural co-infection of Circoviridae torque teno virus (TTV) and porcine circovirus 2 (PCV2) in the swine reproductive apparatus. Semen and organs from 17 boars were tested by nested and real-time PCR. PCV2 was amplified from semen (47%), lymph nodes (84.6%) and testicles (35.3%). TTV2 was amplified from 16/17 testis and 13/13 lymph nodes. TTV1 DNA was detect...
Torque teno virus is a human non-enveloped singlestranded circular DNA virus with icosahedral symmetry and a particle size of approximately 30 nm. TTV was first characterised as a blood-borne virus and was initially referred to as transfusion-transmitted virus (Nishizawa et al. 1997). Its negative-sense genome is 3.6-3.9 kb in size (Mushahwar et al. 1999). Recently, it was renamed Torque teno v...
New diseases in marine animals are emerging at an increasing rate, yet methodological limitations hinder characterization of viral infections. Viral metagenomics is an effective method for identifying novel viruses in diseased animals; however, determining virus pathogenesis remains a challenge. A novel anellovirus (Zalophus californianus anellovirus, ZcAV) was recently reported in the lungs of...
