New species and new records of priceiella (phthiraptera: ischnocera: brueelia-complex) from south china

J Parasitol. 2021 Nov 1;107(6):863-877. doi: 10.1645/21-68.ABSTRACTSeven new species of chewing lice in the genus PriceiellaGustafsson and Bush, 2017, are described and illustrated based on specimens collected in south China. They are Priceiella (Camurnirmus) tanydrepanus n. sp. from Garrulax castanotis castanotis (Ogilvie-Grant, 1899); Priceiella (Camurnirmus) nanlingensis n. sp. from Garrulax maesi maesi (Oustalet, 1890); Priceiella (Thescelovora) brutifrons n. sp. from Turdinus brevicaudatus stevensi (Kinnear, 1925); Priceiella (Thescelovora) chuae n. sp. from Pellorneum albiventre cinnamomeus (Rippon, 1900); Priceiella (Thescelovora) catanachei n. sp. from Stachyris strialata swinhoei Rothschild, 1903; Priceiella (Thescelovora) dehongensis n. sp. from Stachyris nigriceps yunnanensis La Touche, 1921; and Priceiella (Thescelovora) rotundiceps n. sp. from Pomatorhinus ruficollis styani Seebohm, 1884. Several of these new species constitute the second species of Priceiella known from the host, suggesting that local endemism may be high in this louse genus. We also provide new host records for Priceiella (Thescelovora) coleyaeGustafsson et al., 2018, and Priceiella (Thescelovora) austiniGustafsson et al., 2018, and correct the type host subspecies for the latter. Finally, we amend the subgenus descriptions of CamurnirmusGustafsson and Bush, 2017, and ThescelovoraGustafsson and Bush, 2017. As a result of these changes, Priceiella najeriGustafsson et al., 2018, is moved to subge...

In this study, we evaluated the prevalence of head lice infestation among disadvantaged children aged between five to 14 years-old living in five poor conditions located across the Klang Valley, Malaysia. Of total 335 children examined, 14% were positively infected with head lice. Molecular analysis using the universal cytochrome c oxidase subunit I ( COI) barcoding gene on total of 167 head lice collected in this study indicated they are belonging to the A and C clades; confirming the global distribution of clade A and expansion of clade C in Southeast Asia, which is reported for the first time in Malaysia.PMID:35001925 |...

In this study, transcriptomic analysis was used to evaluate the impact of four experimental functional feeds (i.e. 0.3% EPA/DHA+high-ω6, 0.3% EPA/DHA+high-ω6+immunostimulant (IS), 1% EPA/DHA+high-ω6, and 1% EPA/DHA+high-ω3) on Atlantic salmon (Salmo salar) during a single infection with sea lice (L. salmonis) and a co-infection with sea lice and ISAv. The overall objectives were to compare the transcriptomic profiles of skin between lice infection alone with co-infection groups and assess differences in gene expression response among animals with different experimental diets. Atlantic salmon smolts ...

Scientists say ancient human DNA can be recovered from the cement made by head lice to stick eggs to hairAn unusual source of ancient human DNA could help scientists unpick details of our ancestors ’ lives and answer longstanding questions. The source? Nit glue.Scientists studying mummified remains from South America that date back 1,500-2,000 years say they have recovered ancient human DNA from the sticky cement produced by head lice to anchor their eggs to hair.Continue reading...

Mol Biol Evol. 2021 Dec 28:msab351. doi: 10.1093/molbev/msab351. Online ahead of print.ABSTRACTOver the past few decades there has been a growing demand for genome analysis of ancient human remains. Destructive sampling is increasingly difficult to obtain for ethical reasons, and standard methods of breaking the skull to access the petrous bone or sampling remaining teeth are often forbidden for curatorial reasons. However, most ancient humans carried head lice and their eggs abound in historical hair specimens. Here we show that host DNA is protected by the cement that glues head lice nits to the hair of ancient Argentini...
