We report detection of Seoul virus in 3 patients in France over a 2-year period. These patients accounted for 3 of the 4 Seoul virus infections among 434 hantavirus infections (1.7%) reported during this time. More attention should be given to this virus in Europe where surveillance has been focused mostly on Puumala and Dobrava-Belgrade hantaviruses.
among the viruses infecting honey bees, chronic bee paralysis virus (cbpv) is known to induce significant losses in honey bee colonies. cbpv is an unclassified polymorphic single stranded rna virus. using rt-pcr, the virus infections in honey bees can be detected in a rapid and accurate manner. bee samples were collected from 23 provinces of iran, between july-september 2011 and 2012. a total o...
conclusions mp, flub and rsv are the principal contributors to ari in the hubei area, with mixed infections, typically of mp and flub, being the most common pathogens statistically significant between different age groups. background acute respiratory infection (ari) is one of the primary diseases that cause high morbidity and mortality to children especially in developing countries. ari can co...
In 2001 there were 104,187 notifications of communicable diseases in Australia reported to the National Notifiable Diseases Surveillance System (NNDSS). The number of notifications in 2001 was an increase of 16 per cent of those reported in 2000 (89,740) and the largest annual total since the NNDSS commenced in 1991. In 2001, nine new diseases were added to the list of diseases reported to NNDS...
Infection of mice with a series of heterologous viruses causes a reduction of memory CD8(+) T cells specific to viruses from earlier infections, but the fate of the virus-specific memory CD4(+) T cell pool following multiple virus infections has been unknown. We have previously reported that the virus-specific CD4(+) Th precursor (Thp) frequency remains stable into long-term immunity following ...
Bovine viral diarrhoea virus (BVDV) is an important pathogen of dairy cattle. In this study, bulk milk samples representing a total of 4105 milking cows, from 18 dairy cattle herds in the suburb of Mashhad- Iran, were tested for presence of BVDV by the use of a nested reverse transcription polymerase chain reaction (Nested RT- PCR) assay. Non of the cows in the herds had been vaccinated against...
Human Enteroviruses replicate in gastrointestinal tract and are excreted to the sewage system through feces, so isolation of Enteroviruses from sewage can be considered as a sensitive indicator for virus cirulation in society. They are originally given the name of Enteroviruses, but the inadequacy of this term became apparent when some Coxackie and Echoviruses were also found in acute respirato...
Comprehensive population-based data on the role of respiratory viruses in the development of lower respiratory tract infections (LRTIs) remain unclear. We investigated the incidence and effect of single and multiple infections with respiratory viruses on the risk of LRTIs in Vietnam. Population-based prospective surveillance and a case-control study of hospitalised paediatric patients with acut...
Herpes simplex virus infections of humans have been known since ancient times. Contemporary society has witnessed a series of devastating manifestations of herpes simplex virus infections--namely, genital herpes simplex virus infection and neonatal herpes simplex virus infection. With the evolution of society, particularly advances in birth control and increasing promiscuity, the seroprevalence...
