Article Synopsis
- * The study detected and characterized four major pathogens responsible for calf diarrhea using fecal samples from both diarrheic and non-diarrheic calves, identifying various strains of Cryptosporidium, rotavirus A, and bovine coronavirus.
- * Notably, the uncommon G24 genotype of rotavirus A was found for the first time in Ethiopia and Africa, highlighting the need for genetic analysis of these pathogens to improve understanding and control of calf diarrhea.
Article Synopsis
- The study investigates how H9N2 influenza virus can exchange genetic material with other subtypes, affecting its virulence and ability to infect new hosts, including humans.
- Researchers found that H9N2 is genetically compatible with wild bird viruses, particularly regarding the neuraminidase (NA) stalk, which can impact the virus's replication and virulence.
- Results showed that while intact NA-stalk viruses replicate better in avian cells, those with a stalk deletion have improved replication in mammalian and human cells, raising concerns about possible new virus strains emerging in poultry.
Background: Since the beginning of the COVID-19 pandemic, new variants of significance to public health have emerged. Consequently, early detection of new mutations and variants through whole-genome sequencing remains crucial to assist health officials in employing appropriate public health measures.
Methods: We utilized the ARTIC Network SARS-CoV-2 tiled amplicon approach and Nanopore sequencing to sequence 4,674 COVID-19 positive patient samples from Uppsala County, Sweden, between week 15 and 52 in 2021.
We describe a flight-associated infection scenario of seven individuals with a B.1.617.
