Nasopharyngeal swabs vs. saliva sampling for SARS-CoV-2 detection: A cross-sectional survey of acceptability for caregivers and children after experiencing both methods
<p><span>Background: </span><span>Saliva sampling is a promising alternative to nasopharyngeal swabs for SARS-CoV-2 testing, but acceptability data is lacking. We characterize the acceptability of saliva sampling and nasopharyngeal swabs for primary decision makers and their children after experiencing both testing modalities.</span></p> <p><span>Results: </span><span>48 participants and 48 primary decision makers completed the survey. Nasopharyngeal swab acceptability differed between scenarios, ranging 79% [95%CI: 66, 88] to 100% [95%CI: 95, 100]); saliva sampling acceptability was similar across scenarios, ranging 92% [95%CI: 82, 97]) to </span><span> </span><span>98% [95%CI: 89, 99]. 58% of youth described significant pain with nasopharyngeal swabbing, versus none with saliva sampling. 90% of children prefer saliva sampling. 66% of primary decision makers would prefer nasopharyngeal swabbing if it were 10% more sensitive.</span></p> <p><span>Conclusion: </span><span>Though youth prefer saliva sampling over nasopharyngeal swabs, primary decision makers present for testing remain highly accepting of both. Acceptance of nasopharyngeal swabs, however, varies with the testing indication and is influenced by perceived test accuracy. Understanding factors that influence sampling acceptance will inform more successful testing strategies.</span></p>

Fig. 6 in From Spinning Silk to Spreading Saliva: Mouthpart Remodeling in Manduca sexta (Lepidoptera: Sphingidae)
Fig. 6. Labio-hypopharyngeal lobe (lb) of the first instar of MaNdUCa SexTa (medial views of longitudinal cross sections). The spigot (sp) of the first instar is elongate and cone shaped and is connected to the salivarium (spr) via arthrodial membrane (dm = dorsal premento-salivarial muscle, lb = labio-hypopharyngeal lobe, lbr = labrum, lsg = labial gland, md = mandible, pm = prementum, pma = premental arm, spr = salivarium (=silk press), t-pm = tentorio-premental muscle, te-ci = tentorio-cibarial muscle, vm = ventral premento-salivarial muscle).
Fig. 5 in From Spinning Silk to Spreading Saliva: Mouthpart Remodeling in Manduca sexta (Lepidoptera: Sphingidae)
Fig. 5. Labio-hypopharyngeal lobe of the third instar of MaNdUCa SexTa. The salivarium (=silk press, spr) and its muscles (vm, dm) of second and later instars are similar to those of the first instar, indicating that the structure plays a similar role (closing and opening of the salivary orifice) in the saliva-producing instars and the silk-producing first instar. Starting with the second instar, the distal margin of the spinneret is equipped with hollow cuticular evaginations (arrowheads in C) that form a fringe.This brush-like structure might be involved in saliva spreading (dm = dorsal premento-salivarial muscle, pma = premental arm, spr = salivarium (=silk press), vm = ventral premento-salivarial muscle).
Fig. 4 in From Spinning Silk to Spreading Saliva: Mouthpart Remodeling in Manduca sexta (Lepidoptera: Sphingidae)
Fig. 4. Labio-hypopharyngeal lobe of first (A–E) and second (F, G) instars of MaNdUCa SexTa.The spigot (sp) is more than four times as long as wide and clearly protrudes from the convex, sculptureless distal margin of the spinneret in the first instar (A,B) whereas it is almost as wide as long and obscured by the fringed distal margin of the spinneret in later instars (F, G).Two intrinsic (dm, vm) and one extrinsic (t-pm) muscles of the labio-hypopharyngeal lobe have been observed in all instars with similar configuration and relative size. (A) First instar, ventral view. (B) First instar, dorsal view. (C–E) first instar, ventral view. (F) Second instar, ventral view. (G) Second instar, dorsal view (Unlabeled arrowheads in A, F point to campaniform sensilla; arrowheads in C point to the two bands composing dm) (aca = acanthae, con = concavities on posterior premental margin,dm = dorsal premento-salivarial muscle, gal = galea,lp = labial palp,mp = maxillary palp, pgr = palpiger, pm = prementum,pms = premental stipular setae, sis = proximal sclerite of the spinneret, sp = spigot, t-pm = tentorio-premental muscle, vm = ventral premento-salivarial muscle).
Fig. 3 in From Spinning Silk to Spreading Saliva: Mouthpart Remodeling in Manduca sexta (Lepidoptera: Sphingidae)
Fig. 3. The Lyonet's and labial glands in second (A, C, E) and third (B, D, F) instar larvae of MaNdUCa SexTa. The Lyonet's gland (Lg) is larger in the second instar than in the third instar.The chitinized branch (br) of the labial gland (lsg) is apparently closed.The diameter of the epithelial cell cluster composing the Lyonet's gland is less than half the size of the main branch of the labial gland.
Fig. 1 in From Spinning Silk to Spreading Saliva: Mouthpart Remodeling in Manduca sexta (Lepidoptera: Sphingidae)
Fig. 1. Labio-hypopharyngeal lobe of first (A, B) and third (C, D) instar larvae of MaNdUCa SexTa. The labio-hypopharyngeal lobe (lb) forms the ventral wall of the oral foramen (of) and is adjacent to the maxillae (mx) laterally.The spinneret (spin) is the apicomedian portion of the lobe medial to labial palpi (lp) and the sclerotized spigot (sp) is the distalmost part of the common duct of the labial glands bearing the salivary orifice (so).The spinneret is smooth and the spigot protrudes from the apicomedian margin of the spinneret in the first instar (A, B) while the spinneret is equipped with a fringe of hollow, spinelike evaginations (fr) and the spigot does not protrude from the spinneret in later (C, D) instars (a = antenna, cm = mandibular adductor muscle, e = eye, gal = galea, lbr = labrum, lp = labial palp, md = mandible, mp = maxillary palp).
Fig. 2 in From Spinning Silk to Spreading Saliva: Mouthpart Remodeling in Manduca sexta (Lepidoptera: Sphingidae)
Fig. 2. The labio-hypopharyngeal lobe (A, dorsal view) and the labial gland (B–D) in the first instar larva of MaNdUCa SexTa. The Lyonet's gland (Lg), is composed of 10–12 epithelial cells surrounding the proximal branch (br) off the main lumen of the labial gland (lsg). The cells of the Lyonet's gland possess enlarged nuclei (n) and are filled with secretory vesicles (v). A, B volume-rendered CLSM micrographs, C CLSM micrographs, D brightfield micrograph (lp = labial palp, sp = spigot, spin = spinneret).
Coyote prey DNA from coyote saliva to test efficacy of obtaining diet information from oral swabs
<p>Human-carnivore conflicts often involve the depredation of domestic livestock. These depredation events are rarely observed, yet mitigation typically involves identifying the species or individual involved for removal or relocation. We tested a molecular method to identify individuals involved in depredation events using mouth swabs to determine if prey DNA could be detected, and for how long. We fed mule deer (<em>Odocoileus hemionus</em>) meat to captive coyotes (<em>Canis latrans</em>) and swabbed their mouths at five predetermined intervals between 2-72 hours after consumption of the deer meat. We assessed two different molecular forensic methods to analyze the saliva swabs: qPCR for species identification and microsatellites for individual prey identification. We found that qPCR analysis was highly effective, detecting the deer DNA in the coyote saliva for up to 72 hours post-deer consumption. Our results suggest that if an individual carnivore suspected of livestock depredation is captured within 72 hours of a depredation incident, it is possible to confirm their potential involvement with a buccal swab and qPCR analysis. Utilizing this method could aid in more targeted and effective removal of individual problem carnivores as opposed to widespread removal of involved species.</p>
