Earlier studies have shown that Kaposi sarcomas contain cells infected with human herpesvirus (HHV) 6B, and in current studies we report that both AIDSassociated and classic-sporadic Kaposi sarcoma contain HHV-7 genome sequences detectable by PCR. To determine the distribution of HHV-7-infected cells relative to those infected with HHV-6, sections from paraffin-embedded tissues were allowed to ...

Humans carry two nearly identical copies of Survival Motor Neuron gene: SMN1 and SMN2. Mutations or deletions of SMN1, which codes for SMN, cause spinal muscular atrophy (SMA), a leading genetic disease associated with infant mortality. Aberrant expression or localization of SMN has been also implicated in other pathological conditions, including male infertility, inclusion body myositis, amyot...

This study was performed to investigate the frequency of human herpesvirus 6 (HHV-6) infection of the liver in children with a variety of liver diseases and to evaluate the role of HHV-6 infection in pediatric patients with prolonged non-B non-C hepatitis. Detection of the HHV-6 genomes in liver, in peripheral blood mononuclear cells (PBMC), and in plasma was performed by PCR or by in situ hybr...

Streptococcus pneumoniae includes the two serotypes 6A and 6B as well as two recently discovered serotypes, 6C and 6D, in which the wciN gene is replaced by wciN within the cps locus. Serotype 6D occurrence in Asia (2, 4), the Fiji islands (5) and Europe (7, 9) has recently been reported. To our knowledge, we describe here the first description of serotype 6D isolates identified within the Amer...

Background. The development of a pneumococcal vaccine with serotype-independent activity is relevant for the whole world, as this due to high prevalence Streptococcus pneumoniae ( S. ), constant change pathogen serotypes and growth antibiotic-resistant strains. In previous experiments, we revealed protective effect immunization recombinant pneumolysin (rPly) in model systemic infection caused b...
