Molecular Characterization of Noroviruses Causing Acute Gastroenteritis Outbreaks among US Military Recruits, 2013-2023.

Norovirus is the leading cause of acute gastroenteritis (AGE) worldwide. Norovirus outbreaks at military facilities can cause loss of training and working days and increased healthcare utilization, affecting force readiness. During 2013-2023, we enrolled 2,304 US military recruits from 4 basic training facilities to investigate AGE outbreaks among this population.

Two novel recombinant human mastadenovirus D genotypes associated with acute respiratory illness.

Two novel genotypes of species human mastadenovirus D designated 109 and 110 were isolated from three epidemiologically unrelated cases of acute respiratory disease detected in January 2018 by surveillance efforts at the California/Mexico border. Both genotypes represent examples of intertypic recombination. Genotype D109 is most closely related to genotype D56 (97.

Development, testing and validation of a SARS-CoV-2 multiplex panel for detection of the five major variants of concern on a portable PCR platform.

Many SARS-CoV-2 variants have emerged during the course of the COVID-19 pandemic. These variants have acquired mutations conferring phenotypes such as increased transmissibility or virulence, or causing diagnostic, therapeutic, or immune escape. Detection of Alpha and the majority of Omicron sublineages by PCR relied on the so-called S gene target failure due to the deletion of six nucleotides coding for amino acids 69-70 in the spike (S) protein.

Mutations in CSPP1 lead to classical Joubert syndrome.

Joubert syndrome and related disorders (JSRDs) are genetically heterogeneous and characterized by a distinctive mid-hindbrain malformation. Causative mutations lead to primary cilia dysfunction, which often results in variable involvement of other organs such as the liver, retina, and kidney. We identified predicted null mutations in CSPP1 in six individuals affected by classical JSRDs.
