[Vertical transmission of human coronavirus. Prospective pilot study].

Unlabelled: Human coronaviruses (HCoV) have been implicated in neonatal nosocomial respiratory infection. Prior to our study, several cases of neonatal infection were observed in infants born at our hospital. This prospective pilot monocentric pilot study investigates the possibility of maternofetal transmission of HCoV responsible for cases of neonatal infection observed within the first 24 hours of life.

Renal failure in the course of reactivation of varicella-zoster virus infection in a renal transplant recipient.

Renal failure developed in a 20-year-old female renal transplant recipient in the course of reactivation of varicella-zoster virus infection. The patient was treated with acyclovir and immunosuppression was continued. The year later renal function in the transplanted kidney was satisfactory.

Avalon virus, Sakhalin group (Nairovirus, Bunyaviridae) from the seabird tick Ixodes (Ceratixodes) uriae White 1852 in France.

Nine strains of Avalon virus were isolated from Ixodes uriae ticks collected in the Cape Sizun seabird reserve, Brittany, from 1979 to 1985, during a longitudinal study of consequences of tick-borne infections for kittiwakes (Rissa tridactyla). Avalon virus strains isolated in France proved difficult to study owing to the weak infectious titres they exhibited in suckling mice or cultured cells. However, some interesting data concerning the ecology of virus infection and the morphology of the virions were obtained and are discussed.
