Hepatitis G virus/GB virus C (HGV/GBV-C) is a blood-borne flavivirus of humans that was first characterized in 1995. While up to 80% of acutely infected individuals spontaneously clear the virus, chronic viraemia is common and can persist for up to 16 years. 1 The production of antibodies to the HGV/GBV-C envelope protein E2 has been associated with the clearance of the virus and is believed to protect against reinfection. 2 In communities in developed countries, HGV/GBV-C has a high prevalence… 
High Rates of Detection of Respiratory Viruses in Tonsillar Tissues from Children with Chronic Adenotonsillar Disease
Respiratory viruses are highly prevalent in adenoids and palatine tonsils of patients with chronic tonsillar diseases, and persistence of these viruses in tonsils may stimulate chronic inflammation and play a role in the pathogenesis of these diseases.

Measles-type viral cytopathic effect was discovered on histological examination of tonsillar tissue after therapeutic tonsillectomy for PFAPA, and molecular testing showed the left tonsil was positive for measles RNA by reverse transcription polymerase chain reaction (RT-PCR) while the righttonsil was inconclusive (weakly positive).
Measles Virus Infection and Subacute Sclerosing Panencephalitis
Treatment with inosiplex and interferons may induce temporary stabilization or remission in about 30–35 % of the cases and immunization against measles virus and maintenance of immunization rates above 90 % in the population are of extreme importance for the prevention of these debilitating or fatal disorders.

Detection of common respiratory viruses in tonsillar tissue of children with obstructive sleep apnea
Examination of tonsils for the presence of respiratory viruses' nucleic acids in children with OSA, and in children without OSA (undergoing surgery for recurrent throat infections (RI)).
Mise en évidence de l'entrée cellulaire du virus Nipah par macropinocytose : bases moléculaires et inhibition
En etudiant la regulation negative de leur recepteur ephrineB2, j'ai pu mettre en evidence un mecanisme d'entree endocytique pour le virus Nipah : la macropinocytose.


Association of antibody to GB virus C (hepatitis G virus) with viral clearance and protection from reinfection.
Anti-GBV-C is highly associated with viral clearance and protection from reinfection, and studies using RNA testing alone may significantly underestimate the occurrence of GBV- C infection.
Hepatitis G virus infection in children on dialysis and after renal transplantation
A combination of the reverse transcription-polymerase chain reaction and a new diagnostic test for antibodies against the viral envelope protein E2 was used to assess the prevalence of hepatitis G virus (GBV-C/HGV) infection in sera of Hungarian children on hemodialysis or peritoneal dialysis, as well as insera of renal transplant patients (RTx).
Age‐specific prevalence and genetic diversity of GBV‐C/hepatitis G virus in Brazil
The results suggest that sexual transmission of GBV‐C/HGV might occur and that the virus could be eliminated after a long period of infection.
Detection of measles virus genome in lymphocytes from asymptomatic healthy children
It is concluded that asymptomatic measles infection is common but would rarely become a source of transmission because of negative PCR in NPS.
G Virus in the General Population and in Patients on Hemodialysis
HGV is transmitted by blood transfusion and within the hemodialysis unit itself, and HGV does notseem to injure hepatocytes.
Detection and Sequencing of Measles Virus from Peripheral Mononuclear Cells from Patients with Inflammatory Bowel Disease and Autism
Persistence of measles virus was confirmed in PBMC in some patients with chronic intestinal inflammation and sequences obtained from the patients with ulcerative colitis and children with autism were consistent with being vaccine strains.
Detection of Measles Virus mRNA from Autopsied Human Tissues
Measles virus mutants commonly persist in apparently healthy individuals, and sequence analysis revealed frequent mutations in the corresponding viral protein.
Further evidence of the absence of measles virus genome sequence in full thickness intestinal specimens from patients with Crohn's disease
The study supports previous findings produced by this laboratory and others using highly sensitive measles virus specific PCR diagnostic technology and systematically examined samples obtained at resection from patients with Crohn's disease.
Quantities of Clostridium botulinum organisms and toxin in feces and presence of Clostridium botulinum toxin in the serum of an infant with botulism
A 7-week-old boy presented with symptoms and signs characteristic of infant botulism, and the diagnosis was confirmed by the detection of Clostridium botulinum type A organisms and toxin in the
Botulism in the United States: A Clinical and Epidemiologic Review
A clinical overview of botulism is provided and the U.S. Botulism Surveillance System is described to help clinicians recognize and treat patients with mechanical ventilation and early administration of antitoxin in the event of terrorist use of botulinum toxin.
