Potent in vitro activity of β-D-4'-chloromethyl-2'-deoxy-2'-fluorocytidine against Nipah virus.

In this study, we tested ALS-8112 against NiV and other major human respiratory pneumo- and paramyxoviruses in 2 human lung epithelial cell lines, and demonstrated the ability of ALS-8112 to reduce infectious wild-type NiV yield by over 6 orders of magnitude with no apparent cytotoxicity. However, further cytotoxicity testing in primary cells and bone marrow progenitor cells indicated cytotoxicity at higher concentrations of ALS-8112. Our results warrant the evaluation of lumicitabine against NiV infection in relevant animal models. PMID: 31935422 [PubMed - as supplied by publisher]

SUMMARY: When preparing for the coronavirus disease 2019 pandemic and its effects on the CNS, radiologists should be familiar with neuroimaging appearances in past zoonotic infectious disease outbreaks. Organisms that have crossed the species barrier from animals to humans include viruses such as Hendra, Nipah, Severe Acute Respiratory Syndrome, and influenza, as well as bacteria and others. Brain CT and MR imaging findings have included cortical abnormalities, microinfarction in the white matter, large-vessel occlusion, and features of meningitis. In particular, the high sensitivity of diffusion-weighted MR imaging in det...

Background: Nipah virus (NiV) infection is a zoonotic disease. Bangladesh identified first NiV in 2004; until 2019, Bangladesh reported 307 NiV cases with 70% case fatality rate (CFR). Drinking raw date palm sap (RDPS) and human-to-human infection are common modes of transmission. Study showed>3% contacts might develop NiV following exposure for>12 –24h. In February 2019, four deaths and one critically ill patient were reported in a northern district of Bangladesh. We investigated the outbreak to identify source, mode of transmission and establish control measures.

Nipah virus (NiV) is a fatal zoonotic agent that was first identified amongst pig farmers in Malaysia in 1998, in an outbreak that resulted in 105 fatal human cases. That epidemic arose from a chain of infecti...

It wasn’t greed, or curiosity, that made Li Rusheng grab his shotgun and enter Shitou Cave. It was about survival. During Mao-era collectivization of the early 1970s, food was so scarce in the emerald valleys of southwestern China’s Yunnan province that farmers like Li could expect to eat meat only once a year–if they were lucky. So, craving protein, Li and his friends would sneak into the cave to hunt the creatures they could hear squeaking and fluttering inside: bats. Li would creep into the gloom and fire blindly at the vaulted ceiling, picking up any quarry that fell to the ground, while his companion...

Licensed vaccines or therapeutics are rarely available for pathogens with epidemic or pandemic potential. Developing interventions for specific pathogens and defining generalizable approaches for related pathogens is a global priority and inherent to the UN Sustainable Development Goals. Nipah virus (NiV) poses a significant epidemic threat, and zoonotic transmission from bats-to-humans with high fatality rates occurs almost annually. Human-to-human transmission of NiV has been documented in recent outbreaks leading public health officials and government agencies to declare an urgent need for effective vaccines and therape...

ettil Viral outbreaks of varying frequencies and severities have caused panic and havoc across the globe throughout history. Influenza, small pox, measles, and yellow fever reverberated for centuries, causing huge burden for economies. The twenty-first century witnessed the most pathogenic and contagious virus outbreaks of zoonotic origin including severe acute respiratory syndrome coronavirus (SARS-CoV), Ebola virus, Middle East respiratory syndrome coronavirus (MERS-CoV) and Nipah virus. Nipah is considered one of the world’s deadliest viruses with the heaviest mortality rates in some instances. It is known...

The northern side of Chatuchak Weekend Market feels a bit like Noah has hit hard times and decided to offload the entire contents of his Ark. In wooden cages, bright-plumed fighting cocks squawk and peck. Around the corner are snakes in plastic takeout containers, prices scrawled on them in sharpie. Hairless squirrel kits snooze in a pile as a meerkat and giant iguana gaze on. A pygmy monkey leaps about with a furious scowl, perhaps indignant at the 30,000 baht ($950) price tag fixed to his enclosure. Across the narrow alleyway, a lynx prowls restlessly within its cage. “He’s 250,000 baht [$7,900],” says ...

Nipah virus is an emerging pathogenic paramyxovirus responsible for sporadic and isolated outbreaks of severe respiratory and neurologic disease in Southern Asia. As a zoonotic virus, disease can manifest in both animals and human with indigenous fruit bats acting as natural reservoirs of the virus. The effects of viral infection vary from acute respiratory distress to fatal encephalitis. There are currently no approved therapeutics or vaccines against the virus, and growing concerns that this highly pathogenic infection has the potential to cause larger epidemics capable of inflicting significant mortality burden.Like the...

A recent outbreak of Nipah virus (NiV) in India has caused 17 deaths among people living in districts of Kerala state. Its zoonotic nature as well as high rate of human-to-human transmission has led researchers worldwide to work high for understanding the different aspects of the NiV. We performed a codon usage analysis based on publicly available nucleotide sequences of NiV and its host adaptation along with other members of genus Henipavirus in ten hosts. NiV genome encodes nine open reading frames; and overall, no significant bias in codon usage was observed. Aromaticity of proteins had no impact on codon usage. An anal...
