Theiler's virus causes a persistent infection and a demyelinating disease of mice which is a model for multiple sclerosis. Susceptibility to viral persistence maps to several loci, including the interferon gamma locus. Inactivating the gene coding for the interferon gamma receptor makes 129/Sv mice susceptible to persistent infection and clinical disease, whereas inactivating the interferon gam...
Nontypable Haemophilus influenzae (NTHi) has emerged as an important opportunistic pathogen causing infection in adults suffering obstructive lung diseases. Existing evidence associates chronic infection by NTHi to the progression of the chronic respiratory disease, but specific features of NTHi associated with persistence have not been comprehensively addressed. To provide clues about adaptive...
Human coronaviruses (HuCV) cause common colds. Previous reports suggest that these infectious agents may be neurotropic in humans, as they are for some mammals. With the long-term aim of providing experimental evidence for the neurotropism of HuCV and the establishment of persistent infections in the nervous system, we have evaluated the susceptibility of various human neural cell lines to acut...
AIMS Surgery in patients with infective endocarditis (IE) can be elective (upon completion of antibiotic treatment) or urgent (before antibiotic treatment has ended) when the clinical course is unfavourable. However, urgent surgery for left-sided endocarditis is associated with high mortality. The aims of this study were to describe the profile of patients with left-sided endocarditis who under...
A causal role of herpes simplex infection in persistent epithelial defect following penetrating keratoplasty (PKP) has been documented in the past. Instead, not much information is available on the role of adenovirus infection in delayed epithelization following PKP. Here, we describe a case of persistent epithelial defect due to adenoviral infection keratitis confirmed by PCR analysis. Adenovi...
A calf persistently infected by Hobi-like pestivirus was monitored for about 6 months, displaying clinical signs typical of bovine viral diarrhea virus persistent infection and shedding the virus through all body secretions, with maximal titers detected in urine. This report provides new insights into the pathogenesis of the emerging pestivirus.
