Sucking lice of the genus <i>Hoplopleura</i> (Anoplura: Insecta) from Australian Muridae

Eighty-one H. chrysogaster from nineteen localities in Victoria and South Australia were examined for helminths. One acanthocephalan Corynosoma stanleyi: and one cestode, Hymenolepis diminuta, were found. Of the trematodes six were identified to species: Echinoparyphium hydromyos, Fibricola minor, F. intermedius, Microphaflus minutus, Maritrema oocysta and Plagiorchis jaenschi; two were placed in the families Heterophyidae, and Psilostomidae, both new locality records; and two new species Notocotylus sp. nov. and Paramonostomum sp. nov. were found. There were six nematode species: Synhimantus australiensis, Antechiniella suffodiax, Antechiniella sp., Woolleya hydromyos as well as Parastrongyloides sp. and a heteroxynematid both new host records. H. diminuta was the most prevalent helminth, with M. minutus and S. australiensis the most prevalent trematode and nematode respectively. A checklist of helminths from H. chrysogaster is given and comparisons between infections of Tasmanian, Victorian and South Australian hosts are made.Thirty-three of these water rats, trapped live in Victoria, were also examined for protozoa. Klossiella hydromyos, Toxoplasma gondii and Sarcocystis sp. were found. Twenty of the Victorian hosts were examined for ectoparasites. Three mites; Paraspeleognathopsis derricki, Murichirus parahydromys, and Radfordia sp.; one tick, Zxodes tasmani; one louse, Hoplopleura bidentata; and three flea species, Acanthopsylla rothschildi and Echidnophaga spp. were found. 0004-959X/90/060657$03 .OO

“…The third antennal segment of H. villosissima n. sp. is not sexually dimorphic, which is different from Hoplopleura irritans Kuhn & Ludwig, 1967 [ 8 ]. The dorsal marginal head setae (DMHS) of the new species are not aligned; this is different from Hoplopleura gyomydis Kuhn & Ludwig, 1967 [ 8 ] and Hoplopleura mastacomydis Kuhn & Ludwig, 1967 [ 8 ] in which the DMHS are aligned in a row.…”

A new species of sucking louse Hoplopleura villosissima n. sp. (Psocodea: Phthiraptera: Hoplopleuridae) and a new host record of the spiny rat louse Polyplax spinulosa Burmeister, 1839 (Psocodea: Phthiraptera: Polyplacidae) from the long-haired rat Rattus villosissimus Waite (Rodentia: Muridae) in Australia

BackgroundThe sucking louse fauna of endemic Australian rodents has been under-studied for decades. Sixty-five species of native rodents have been recorded in Australia. However, only 11 species of lice have been reported from 11 species of endemic Australian rodents.ResultsWe describe a new species of sucking louse, Hoplopleura villosissima Wang (Psocodea: Phthiraptera: Hoplopleuridae), and report a new host record of the spiny rat louse, Polyplax spinulosa Burmeister, 1839 (Psocodea: Phthiraptera: Polyplacidae), from the long-haired rat, Rattus villosissimus Waite (Rodentia: Muridae), which is endemic to Australia.ConclusionsThis study is the first record of sucking louse from R. villosissimus and the first record of a species of Polyplax Enderlein, 1904 from an endemic Australian rodent. This study brings the total number of sucking louse species in endemic Australian rodents from 11 to 13. Previously, only the introduced brown rat, Rattus norvegicus Berkenhout and the black rat, Rattus rattus Linnaeus were recorded as the hosts of P. spinulosa in Australia. Because R. villosissimus overlaps with R. rattus in distribution but not with R. norvegicus, we propose that P. spinulosa transferred to R. villosissimus from R. rattus.

“…The ecto‐ and endo‐parasites were washed in distilled water and clarified in lactophenol before morphological examination. Ecto‐ and endo‐parasites carried by rodents were identified to genus or species level using morphological criteria (Roberts, ; Mawson, ; Domrow, ; Kuhn and Ludwig, ; Traub and Dunnet, ; Taffs, ; Centers for Disease Control and Prevention ).…”

In 1964, Brucella was isolated from rodents trapped in Wooroonooran National Park (WNP), in Northern Queensland, Australia. Genotyping of bacterial isolates in 2008 determined that they were a novel Brucella species. This study attempted to reisolate this species of Brucella from rodents living in the boundary area adjacent to WNP and to establish which endo- and ecto-parasites and bacterial agents were being carried by non-indigenous rodents at this interface. Seventy non-indigenous rodents were trapped [Mus musculus (52), Rattus rattus (17) and Rattus norvegicus (1)], euthanized and sampled on four properties adjacent to the WNP in July 2012. Organ pools were screened by culture for Salmonella, Leptospira and Brucella species, real-time PCR for Coxiella burnetii and conventional PCR for Leptospira. Collected ecto- and endo-parasites were identified using morphological criteria. The percentage of rodents carrying pathogens were Leptospira (40%), Salmonella choleraesuis ssp. arizonae (14.29%), ectoparasites (21.42%) and endoparasites (87%). Brucella and C. burnetii were not identified, and it was concluded that their prevalences were below 12%. Two rodent-specific helminthic species, namely Syphacia obvelata (2.86%) and Nippostrongylus brasiliensis (85.71%), were identified. The most prevalent ectoparasites belonged to Laelaps spp. (41.17%) followed by Polyplax spp. (23.53%), Hoplopleura spp. (17.65%), Ixodes holocyclus (17.64%) and Stephanocircus harrisoni (5.88%), respectively. These ectoparasites, except S. harrisoni, are known to transmit zoonotic pathogens such as Rickettsia spp. from rat to rat and could be transmitted to humans by other arthropods that bite humans. The high prevalence of pathogenic Leptospira species is of significant public health concern. This is the first known study of zoonotic agents carried by non-indigenous rodents living in the Australian wet-tropical forest interface.
