The 23rd Annual Meeting of the Rocky Mountain Virology Association.

Located 50 miles west of Fort Collins, Colorado, Colorado State University's Mountain Campus in Pingree Park hosted the 23rd annual Rocky Mountain Virology Association meeting in 2023 with 116 participants. The 3-day event at the end of September consisted of 28 talks and 43 posters that covered the topics of viral evolution and surveillance, developments in prion research, arboviruses and vector biology, host-virus interactions, and viral immunity and vaccines. This year's Randall Jay Cohrs keynote presentation covered the topic of One Health and emerging coronaviruses.

Galbut Virus Infection Minimally Influences Fitness Traits in a Strain and Sex-Dependent Manner.

Galbut virus (family ) infects and can be transmitted vertically from infected mothers or infected fathers with near perfect efficiency. This form of super-Mendelian inheritance should drive infection to 100% prevalence, and indeed, galbut virus is ubiquitous in wild populations. However, on average, only about 60% of individual flies are infected.

The 22nd Annual Meeting of the Rocky Mountain Virology Association.

Following the cause established twenty-two years ago, the 22nd Annual Rocky Mountain Virology Association meeting was held amidst the resplendent Rocky Mountains within the Arapahoe and Roosevelt National Forests. 116 intellectuals including both regional and international scientists as well as trainees gathered at the Colorado State University Mountain Campus for this three-day forum. Current trends in virology and prion disease research were discussed both in talks and poster presentations.

The 21st Annual Meeting of the Rocky Mountain Virology Association.

Nestled within the Rocky Mountain National Forest, 114 scientists and students gathered at Colorado State University's Mountain Campus for this year's 21st annual Rocky Mountain National Virology Association meeting. This 3-day retreat consisted of 31 talks and 30 poster presentations discussing advances in research pertaining to viral and prion diseases. The keynote address provided a timely discussion on zoonotic coronaviruses, lessons learned, and the path forward towards predicting, preparing, and preventing future viral disease outbreaks.

Partitiviruses Infecting Drosophila melanogaster and Aedes aegypti Exhibit Efficient Biparental Vertical Transmission.

Partitiviruses are segmented, multipartite double-stranded RNA (dsRNA) viruses that until recently were only known to infect fungi, plants, and protozoans. Metagenomic surveys have revealed that partitivirus-like sequences are also commonly associated with arthropods. One arthropod-associated partitivirus, galbut virus, is common in wild populations of To begin to understand the processes that underlie this virus's high global prevalence, we established colonies of wild-caught infected flies.
