Pathogen-associated molecular patterns (PAMPs) derived from Leishmania and bacteria increase gene expression of antimicrobial peptides and gut surface proteins in sand flies
Int J Parasitol. 2024 Apr 14:S0020-7519(24)00075-4. doi: 10.1016/j.ijpara.2024.04.005. Online ahead of print.ABSTRACTThe interaction between pathogens and vectors' physiology can impact parasite transmission. Studying this interaction at the molecular level can help in developing control strategies. We study leishmaniases, diseases caused by Leishmania parasites transmitted by sand fly vectors, posing a significant global public health concern. Lipophosphoglycan (LPG), the major surface glycoconjugate of Leishmania, has been described to have several roles throughout the parasite's life cycle, both in the insect and verteb...

The geographic limits and life history of the tropical brown dog tick, Rhipicephalus linnaei (Audouin, 1826), in Australia with notes on the spread of Ehrlichia canis
Int J Parasitol. 2024 Apr 10:S0020-7519(24)00074-2. doi: 10.1016/j.ijpara.2024.04.004. Online ahead of print.ABSTRACTThe tropical brown dog tick, Rhipicephalus linnaei, is a tick of much medical, veterinary, and zoonotic importance. This tick has a nearly world-wide distribution due to its ability to survive and propagate in kennels and houses. Rhipicephalus linnaei is the vector of Ehrlichia canis, the causative agent of canine monocytic ehrlichiosis, an often debilitating disease of canids and, occasionally, humans. To prevent incursion of E. canis into Australia, dogs entering Australia have been required to have a nega...

Effects of regional coordination of salmon louse control in reducing negative impacts of salmonid aquaculture on wild salmonids
Int J Parasitol. 2024 Apr 10:S0020-7519(24)00073-0. doi: 10.1016/j.ijpara.2024.04.003. Online ahead of print.ABSTRACTParasitic salmon lice (Lepeoptheirus salmonis) are a constraint to the sustainable growth of salmonids in open net pens, and this issue has caused production to level off in recent years in the most aquaculture-intensive areas of Norway. The maximum allowed biomass at a regional level is regulated by using the so-called "traffic light" system, where salmon louse-induced mortality of migrating wild salmon post-smolts is evaluated against set targets. As a case study, we have investigated how a specific aquacu...

Searching for common patterns in parasite ecology: species and host contributions to beta-diversity in helminths of South African ungulates and fleas of South American rodents
Int J Parasitol. 2024 Apr 9:S0020-7519(24)00071-7. doi: 10.1016/j.ijpara.2024.04.001. Online ahead of print.ABSTRACTWe searched for common patterns in parasite ecology by investigating species and host contributions to the beta-diversity of infracommunities (=assemblages of parasites harboured by a host individual) in helminths of three species of South African ungulates and fleas of 11 species of South American rodents, assuming that a comparison of patterns in distinctly different parasites and hosts would allow us to judge the generality or, at least, commonness of these patterns. We used data on species' composition an...

Epidemiological investigation of Entamoeba in wild rhesus macaques in China: a novel ribosomal lineage and genetic differentiation of Entamoeba nuttalli
Int J Parasitol. 2024 Apr 9:S0020-7519(24)00072-9. doi: 10.1016/j.ijpara.2024.04.002. Online ahead of print.ABSTRACTWild rhesus macaques are a potential source of zoonotic parasites for humans, and Entamoeba spp. are common intestinal parasites. To investigate the prevalence of Entamoeba in wild rhesus macaques in China and explore the genetic differentiation of the potentially pathogenic species Entamoeba nuttalli, a total of 276 fecal samples from five populations at high altitudes (HAG, 2,800-4,100 m above sea level) and four populations at low altitudes (LAG, 5-1,000 m above sea level) were collected. PCR methods based...

Enigmatic host-mite relationships: Unraveling the distribution of quill mites on Birds-of-Paradise
This study presents an analysis of mite material collected from 22 avian species belonging to the family Paradisaeidae (Passeriformes), revealing the presence of four mite species belonging to four genera: Syringophiloidus attenboroughi n. sp., Peristerophila regiusi n. comb., Picobia frankei, and Gunabopicobia garylarsoni. In the present work, the genus Neoperisterophila is synonymized with the genus Peristerophila. While the genera Syringophiloidus and Picobia were expectedly found on paradisaeid birds, given their prevalence in passerines, the presence of Peristerophila and Gunabopicobia was intriguing, suggesting poten...
