A Methodology for Determining Which Diseases Warrant Care in a High-Level Containment Care Unit

Viruses, 2019
Although the concept of high-level containment care (HLCC or ‘biocontainment’), dates back to 1969, the 2014−2016 outbreak of Ebola virus disease (EVD) brought with it a renewed emphasis on the use of specialized HLCC units in the care ...

Infectivity of Norovirus GI and GII from Bottled Mineral Water during a Waterborne Outbreak, Spain

Emerging Infectious Diseases, 2020
During a waterborne outbreak of norovirus in Spain, we estimated 50% illness doses for a group of exposed (secretor) persons to be 556 (95% CI 319–957) genome copies/day for norovirus GI and 2,934 (95% CI 1,683–5,044) genome copies/day for norovirus GII.

Tolerance to mutations in the foot-and-mouth disease virus integrin-binding RGD region is different in cultured cells and in vivo and depends on the capsid sequence context. [PDF]

, 2008
Engineered RNAs carrying substitutions in the integrin receptor-binding Arg-Gly-Asp (RGD) region of foot-and-mouth disease virus (FMDV) were constructed (aa 141-147 of VP1 capsid protein) and their infectivity was assayed in cultured cells and suckling

A quantitative assessment of the prion risk associated with wastewater from carcase-handling facilities [PDF]

, 2013
Wastewater from facilities processing livestock that may harbor transmissible spongiform encephalopathies (TSEs) infectivity is permitted under license for application to land where susceptible livestock may have access. Several previous risk assessments

Helicoverpa armigera nucleopolyhedrovirus occlusion-derived virus-associated protein, HA100, affects oral infectivity in vivo but not virus replication in vitro [PDF]

, 2011
ORF100 (ha100) of Helicoverpa armigera nucleopolyhedrovirus (HearNPV) has been reported as one of the unique genes of group II alphabaculoviruses encoding a protein located in the occlusion-derived virus (ODV) envelope and nucleocapsid.

Propidium Monoazide Combined With RT-qPCR Detects Infectivity of Porcine Epidemic Diarrhea Virus

Frontiers in Veterinary Science, 2022
Reverse transcription-quantitative polymerase chain reaction (RT-qPCR) allows sensitive detection of viral particles and viruses in epidemic samples but it cannot discriminate noninfectious viruses from infectious ones.

The Leishmania major BBSome subunit BBS1 is essential for parasite virulence in the mammalian host [PDF]

, 2013
Bardet–Biedl syndrome (BBS) is a human genetic disorder with a spectrum of symptoms caused by primary cilium dysfunction. The disease is caused by mutations in one of at least 17 identified genes, of which seven encode subunits of the BBSome, a protein ...

Dose-response relationship of Ralstonia solanacearum and potato in greenhouse and in vitro experiments

Frontiers in Plant Science, 2022
Ralstonia solanacearum is the causative agent of bacterial wilt of potato and other vegetable crops. Contaminated irrigation water contributes to the dissemination of this pathogen but the exact concentration or biological threshold to cause an infection

Respiratory infection complicating HIV infection [PDF]

Current Opinion in Infectious Diseases, 2008
Respiratory infections remain a major cause of morbidity among HIV-infected persons. Thus, knowledge of recent advances regarding HIV-associated opportunistic pneumonias is crucial for optimal care of HIV-infected persons.Bacterial pneumonia is the most common HIV-associated opportunistic pneumonia in the USA and its incidence remains appreciable ...
