This study documents the parasite assemblage of Rattus colletti (Thomas, 1904) from the Adelaide River flood plain, Northern Territory, Australia. In total, six species of helminth (comprising two cestodes, one trematode and three nematodes), and four species of arthropod (comprising one tick, one mite, one flea (identified to family level) and one louse (identified to generic level)) were found. In spite of the hosts being present in high numbers the helminth assemblage was depauperate, characterised by low prevalence and abundance, both being higher in wet seasons. More helminths were found in larger animals. The most prevalent helminth was from the Trichostrongylina, Nippostrongylus typicus (Mawson, 1961). The assemblage was characterised as having two heirloom species (N. typicus and Hymenolepis diminuta (Rudolphi, 1819)), a host capture (Raillietina celebensis (Janicki, 1902) and a cosmopolitan species (Mastophorus muris (Gmelin, 1790)) as well as occasional infections. When compared with the helminths from a single population of Rattus sordidus (Gould, 1858) a similar number of species were found, three species being in common, and both were depauperate when compared with the more extensively surveyed faunas of Rattus fuscipes (Waterhouse, 1839) and Rattus leucopus (Gray, 1858).

This study documents the parasite assemblage of Liasis fuscus Peters, 1873 from the Adelaide River flood plain, Northern Territory, Australia. In total, nine species of helminth (comprising three cestodes and six nematodes), one pentastome and one protozoan were found in 180 water pythons, with the Nematoda being the dominant and most diverse group, and a cestode, Bothridium ornatum Maplestone & Southwell, 1923, the most prevalent species. In spite of the hosts being present in high numbers the helminth assemblage was depauperate, characterised by low prevalence, intensity, frequency and abundance of species, with neither season nor sex of host affecting abundance. There were, however, significant differences between ages of hosts, juveniles having fewer parasites, and seasonal diversity, with the wet season of 2004 and the dry of 2005 the most similar. Of the Australian python species analysed Morelia spilota (Lacépède, 1804) had the highest species richness. The lower species richness found in L. fuscus was possibly due to its unusual biology. Biogeographic relationships of the parasite fauna of L. fuscus are diverse, connections with Africa, Asia, and South America being noted.

Abstract Introduction Discovered in 1911 by Frederick Forssman, the Forssman (Fs) antigen (Ag) expression varies among species, being rarely present on human red blood cells (RBC). In 1987 three unrelated English families were identified with a phenotype designed Apae which was later classified as the 31st blood group: FORS. Since antibodies (Ab) anti-Fs has natural occurrence and the expression of the Ag occurs on the surface of the RBC, body fluids and organs, raises a potential role for this antigen in transfusion and transplantation implications. Objectives Our main goals were to evaluate the prevalence of anti-Fs Ab and clarify its impact in transfusional medicine by classifying the type of immunoglobulin (Ig) involved. Methodology 3-5% sheep RBC suspension with positive expression for Fs Ag was used to evaluate the presence of Ab anti-Fs in plasma samples from a Portuguese population of blood donor and classify the immunoglobulin involved. Standard tube technique was used in all the experiments. Results From a total of 11877 donors, 117 (0,99%) showed weak reactions (between 0 and 1 in a scale from 0 to 4). All these samples would be further studied to evaluate the presence of the Arg296Gln in the GBGT1 gene. Also, from the 192 samples studied to classify the Ab involved, 52% revealed to be only IgM, being the rest a mixture between IgG and IgM. Conclusion The population studied revealed few samples with negative reaction against the sheep RBC confirm the low-prevalence of this blood group. The majority from the Ab to be IgM was also corroborated although the presence of an IgG portion can be clinically significant once it can cross the placental barrier.

A new tribe, the Stereomerini, is established for four unusual genera: Stereomera Arrow, Termitaxis Krikken, Australoxenella n.gen., and Bruneixenus n.gen. The previously described genera are monotypic, as is Bruneixenus, the type species being B. squamosus n.sp. from Brunei. Australoxenella contains two new species, A. humptydooensis, type species, and A. bathurstensis, both from the Northern Territory, Australia. The relationships of the new tribe are analyzed and compared with the most closely related tribe, the Rhyparini, in the Aphodiinae. The tribe Rhyparini is redefined, and the genus Notocaulus Quedenfeldt is transferred to the Eupariini. A key to genera in both the Stereomerini and the Rhyparini is presented, important characters are illustrated, a cladogram is given, and convergence is discussed.
