Damhorst G, Martin S, Wilber E, Verkerke H, Goodman M, Lam W
Open Forum Infect Dis . 2024 Oct; 11(10):ofae561. PMID: 39431150
Background: Studies of the diagnostic performance of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) nucleocapsid antigen in blood (antigenemia) have reached variable conclusions. The potential utility of antigenemia measurements as...

Bassit L, Bowers H, Greenleaf M, Sabino C, Lai E, Yu G, et al.
STAR Protoc . 2024 Jun; 5(3):103146. PMID: 38905104
The emergence of the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) Alpha variant in 2020 demonstrated the need for reanalysis of diagnostic tests to ensure detection of emerging variants. Here,...

Damhorst G, Lin J, Frediani J, Sullivan J, Westbrook A, McLendon K, et al.
Heliyon . 2024 Mar; 10(6):e27188. PMID: 38500996
Limited data highlight the need to understand differences in SARS-CoV-2 omicron (B.1.1.529) variant viral load between the gold standard nasopharyngeal (NP) swab, mid-turbinate (MT)/anterior nasal swabs, oropharyngeal (OP) swabs, and...

Damhorst G, McLendon K, Morales E, Solis Z, Fitts E, Bowers H, et al.
J Clin Virol . 2024 Mar; 171:105659. PMID: 38430669
Anorectal and oropharyngeal exposures are implicated in sexual transmission of mpox, but authorized assays in the United States are only validated with cutaneous lesion swabs. Diagnostic assays for anorectal and...

Damhorst G, Fujita A, Fitts E, Szabo B, Bowers H, Sabino C, et al.
J Infect Dis . 2023 Nov; 229(Supplement_2):S213-S218. PMID: 38019187
The 2022 mpox outbreak primarily involved sexual transmission among men who have sex with men and disproportionately affected persons with human immunodeficiency virus (HIV). We examined viral dynamics and clinical...

Cheedarla N, Verkerke H, Potlapalli S, McLendon K, Patel A, Frank F, et al.
iScience . 2023 Nov; 26(11):108256. PMID: 37965140
Traditional cellular and live-virus methods for detection of SARS-CoV-2 neutralizing antibodies (nAbs) are labor- and time-intensive, and thus not suited for routine use in the clinical lab to predict vaccine...

Lancelot M, Fibben K, Sullivan J, OSick W, McLendon K, Wu H, et al.
Front Microbiol . 2023 Aug; 14:1219214. PMID: 37608952
Introduction: Swab pooling may allow for more efficient use of point-of-care assays for SARS-CoV-2 detection in settings where widespread testing is warranted, but the effects of pooling on assay performance...

Damhorst G, Schoof N, Nguyen P, Verkerke H, Wilber E, McLendon K, et al.
Open Forum Infect Dis . 2023 May; 10(5):ofad226. PMID: 37213426
Background: Nasopharyngeal qualitative reverse-transcription polymerase chain reaction (RT-PCR) is the gold standard for diagnosis of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection, but it is not practical or sufficient...

Pediatr Infect Dis J . 2023 Jan; 42(2):130-135. PMID: 36638399
Background: Nucleocapsid antigenemia in adults has demonstrated high sensitivity and specificity for acute infection, and antigen burden is associated with disease severity. Data regarding SARS-CoV-2 antigenemia in children are limited....
