AbstractFour families of parasitic mites (Acari: Rhinonyssidae, Ereynetidae, Cytoditidae, and Turbinoptidae) have evolved independently to live inside the nasal passages of birds. A previous survey of nasal mites in Canada drew attention to the dearth of knowledge about these specialised mites, and indicated there were more species of nasal mites to discover in Canada. Since 2008, we have continued to survey nasal mites and herein present the details from infested hosts, 92 host individuals representing 64 species from 11 orders and 23 families. We report 18 new records for species of nasal mites in Canada: 16 Rhinonyssidae, one Ereynetidae, and one Turbinoptidae. No Cytoditidae have yet been recorded in Canada. We also collected five undescribed species of rhinonyssids. A total of 64 host-parasite species records are reported, and of these records, 52 rhinonyssids, one ereynetid, and three turbinoptids are new for Canada. Nasal mites were not collected from 127 host species, and several of these host species were sampled extensively (⩾50 individuals). This research furthers our understanding of avian nasal mites in Canada and highlights the need for continued investigations on these mites.

Black-necked swans (Cygnus melanocoryphus) are endemic to the southern cone of South America. Their range extends from Brazil and Paraguay south to Argentina and Chile. A total of 16 parasite species were collected from 7 swans from the Biobio region, Chile, of which 12 are new records for Chile and 11 represent new host records, Echinostoma trivolvis, Paranomostomum sp., Microsomacanthus sp., Nadejdolepis sp., Retinometra sp., Avioserpens sp., Capillaria skrjabini, Ingrassia cygni, Anatoecus penicillatus, A. icterodes and A. keymeri. A checklist is presented that summarizes sites of infections, localities, life cycles and their intermediate hosts (if known), and the pertinent references to demonstrate the wide diversity of parasites of black-necked swans. Our review of the existing literature (23 publications) along with our own records provided information on a total of 18 families and 27 genera, including 33 described species (some only identified to genus), of which 11 were recorded only in Chile (8 endoparasites and 3 ectoparasites), and 6 only in Argentina (4 endoparasites and 2 ectoparasites). Five parasites are known only from captive swans in European zoos. Parasites recorded from C. melanocoryphus include 23 helminths and 10 ectoparasites (one leech and 9 arthropods).

Fifty specimens of Cichla piquiti were collected from the Paraná River downstream of the Ilha Solteira Hydroelectric Power Station in Brazil and surveyed for endohelminth parasites. All fish were parasitised by at least one helminth species (overall prevalence [P] = 100%). Eight parasite taxa were present: the nematode Procamallanus(Procamallanus) peraccuratus in the intestines; third-stage larvae of the anisakids Contracaecumsp. and Hysterothylacium sp. in the visceral cavity, mesentery and serosa of the stomach and intestines and on the liver and spleen; the trematodes Austrodiplostomum compactum in the eye (metacercariae) and Genarchella genarchella in the stomach; and the cestodes Proteocephalus macrophallus, Proteocephalus microscopicus, and Sciadocephalus megalodiscus in the intestines. Hysterothylaciumsp. larvae (P = 86%) and P. microscopicus (P = 74%) were the most prevalent parasites. Anisakids were more prevalent and abundant in the dry season. A negative correlation between the abundances of Hysterothylacium sp. and P. microscopicuswas observed, suggesting a competitive/antagonistic relationship between these parasites. Cichla piquiti represents a new host for four parasite species. These new records significantly increase the list of parasites of C. piquiti, contributing to the knowledge of the host-parasite relationship and the geographical distribution of these helminths.

Hygrobates salamandrarum Goldschmidt, Gerecke and Alberti, 2002 (Acari, Hydrachnidia, Hygrobatidae) is the first-known water mite parasitizing adult newts. After its description, three further species of newt-parasitizing mites were described and the subgenus Lurchibates Goldschmidt and Fu, 2011 was proposed for the group, now containing four newt-parasitizing mites. Until now, each water mite species parasitizes a different newt species (Table 1), suggesting possible mite-newt co-speciation. In order to test this hypothesis, we need an accurate taxonomy of both of the hosts and parasites. However, the taxonomy of those Asian newt genera known to be parasitized by Lurchibates mites has been substantially revised after the initial description of the H. salamandrarum. To account for these taxonomic changes, we here revise the host-parasite species list and amend the host species name as shown in Table 1.

AbstractThis new checklist is an update of helminths of freshwater fish from Turkey. The last publication of a checklist of helminth parasites of freshwater fish in Turkey was over 11 years ago (Öktener, 2003), and there have been a number of new records. This update includes additional records and allows for the correction of errors and omissions that were present in the preceding version. The revision literature indicated the occurrence of 123 parasite species which included 60 monogeneans, 20 digeneans, 20 cestodes, 11 nematodes, seven acanthocephalans, five annelids from 71 different wild fish (64 native, four transitional, three introduced fish) species from freshwater in Turkey. Parasites not identified to species level are listed separately, and not included in the resulting comments, because of reporting different host species. Cyprinidae, with 50 species, is the dominant family among the examined fish with regard to species diversity

In the spring of 2008, leaf spot was observed on <I>Rhododendron hippophaeoides</I> and <I>Rhododendron obtusum</I>; the causal agent was identified as the rust <I>Chrysomyxa rhododendri</I>. The rust occurs primarily in mountain regions and in the Czech Republic was first observed 105 years ago. In the present study we describe pathogen morphology and symptoms on the two new host species.

The object of this short paper is to record a number of new host species for certain common helminths of birds. These new records show that the host range of some helminths is not so circumscribed as had been previously believed. Most of these parasites have been obtained at routine post-mortem examinations and hence were the result of natural infections in the field. A few however were the result of experimental feedings at this Institute.

SUMMARYHost-parasite checklists are essential resources in ecological parasitology, and are regularly used as sources of data in comparative studies of parasite species richness across host species, or of host specificity among parasite species. However, checklists are only useful datasets if they are relatively complete, that is, close to capturing all host–parasite associations occurring in a particular region. Here, we use three approaches to assess the completeness of 25 checklists of metazoan parasites in vertebrate hosts from various geographic regions. First, treating checklists as interaction networks between a set of parasite species and a set of host species, we identify networks with a greater connectance (proportion of realized host–parasite associations) than expected for their size. Second, assuming that the cumulative rise over time in the number of known host–parasite associations in a region tends toward an asymptote as their discovery progresses, we attempt to extrapolate the estimated total number of existing associations. Third, we test for a positive correlation between the number of published reports mentioning an association and the time since its first record, which is expected because observing and reporting host–parasite associations are frequency-dependent processes. Overall, no checklist fared well in all three tests, and only three of 25 passed two of the tests. These results suggest that most checklists, despite being useful syntheses of regional host–parasite associations, cannot be used as reliable sources of data for comparative analyses.

AbstractCompetition between parasite species or genotypes can play an important role in the establishment of parasites in new host populations. Here, we investigate a mechanism by which a rare parasite is unable to establish itself in a host population if a common resident parasite is already present (a ‘priority effect’). We develop a simple epidemiological model and show that a rare parasite genotype is unable to invade if coinfecting parasite genotypes inhibit each other's transmission more than expected from simple resource partitioning. This is because a rare parasite is more likely to be in multiply-infected hosts than the common genotype, and hence more likely to pay the cost of reduced transmission. Experiments competing interfering clones of bacteriophage infecting a bacterium support the model prediction that the clones are unable to invade each other from rare. We briefly discuss the implications of these results for host-parasite ecology and (co)evolution.
