Surveillance of adenovirus respiratory infections in children in Osaka, Japan.

Surveillance of adenovirus respiratory infections in children in Osaka, Japan. Jpn J Infect Dis. 2017 Sep 11;: Authors: Hiroi S, Morikawa S, Nakata K, Kase T Abstract Human adenovirus (HAdV) strains isolated from respiratory specimens of 139 children between 2008 and 2015 were analyzed with the intent of evaluating the endemic situation of HAdV infections in Osaka, Japan. The cases increased in spring and winter, and the infections were confirmed mainly in children aged ≤ 5 years, comprising 91.9% of the total population examined. Molecular typing of the isolates revealed that the most common types belonged to HAdV-B and HAdV-C, and a case of co-infection with HAdV-C1 and HAdV-C2 was confirmed. The median age of HAdV-E cases were higher than that of HAdV-B and -C cases. These results revealed age and seasonal distribution of respiratory infections caused by HAdVs in children in Osaka, and indicate that the majority of children might have acquired immunity through infection with endemic HAdVs before school age.

AbstractFoodborne viral diseases are a major public health threat and pose a huge burden on the economies of both developed and developing countries. Enteric viruses are the causative agents of most foodborne illnesses and outbreaks. Egypt is classified by WHO among the regions with intermediate to high endemicity for various enteric viruses. This is manifested by the high prevalence rates of different enteric virus infections among Egyptian population such as Hepatitis A and E viruses, human rotaviruses, human noroviruses, human astroviruses, and human adenovirus. Recently, a number of foodborne gastroenteritis and acute ...

Our study highlights the key drivers of infection and shedding dynamics of squirrelpox virus (SQPV) in its reservoir grey squirrel (Sciurus carolinensis) population. To clarify SQPV dynamics in this popul...

Bishop, Suryakant D. Waghela, Maureen Sheahan, Raymond R.R. Rowland, Waithaka MwangiAbstractAfrican Swine Fever Virus (ASFV) causes a hemorrhagic disease in swine and wild boars with a fatality rate close to 100%. Less virulent strains cause subchronic or chronic forms of the disease. The virus is endemic in sub-Saharan Africa and an outbreak in Georgia in 2007 spread to Armenia, Russia, U...

Unfortunately, some vaccines provide only partial protection or in some cases vaccine-mediated immunity may wane rapidly, resulting in either increased susceptibility to that disease or a requirement for more booster vaccinations in order to maintain immunity above a protective level. The durability of a...

AbstractPurpose of ReviewThis review will provide an updated overview of the diagnosis, management, and prevention of adenoviral keratoconjunctivitis.Recent FindingsHuman adenovirus (HAdV) is undergoing nomenclature changes because of whole genome sequencing. Recombination has led to newly identified ocular pathogens like HAdV-D53, HAdV-D54, and HAdV-D56. No quick, highly sensitive and specific diagnostic test is available for ocular adenoviral infections. PCR takes a few hours but is not widely available. Results of using PCR in employees at one medical center support the view of endemic HAdV in the community.SummaryInfec...

To overcome the cost and complexity of current thalassemia ex vivogene therapy protocols, we developed a minimally invasive and readily translatable approach for in vivo HSC gene delivery which abrogates the need for HSC leukapheresis, CD34+ cell selection, ex vivo HSC culture, myeloablation and ultimately, transplantation. Our approach involves HSC mobilization with G-CSF/AMD3100 andintravenous injections of a hybrid vector system consisting ofa CD46-targeting, helper-dependent adenoviral vector and the hyperactive Sleeping Beauty transposase (SB100x) that mediates integration of thevector-encoded -globin and mgmtP140K ge...
