Forest edges affect ectoparasite infestation patterns of small mammalian hosts in fragmented forests in Madagascar.

This study aims to investigate if and how habitat fragmentation affects the composition of ectoparasite communities on small mammalian hosts in two networks of dry deciduous forest fragments in northwestern Madagascar. Forest sites differing in size, proportion of edge habitat and host density were studied in the Ankarafantsika National Park and in the Mariarano region. A total of 924 individuals of two mouse lemur species, Microcebus murinus (n=200) and Microcebus ravelobensis (n=426), and two rodent species, endemic Eliurus myoxinus (n=114) and introduced Rattus rattus (n=184), were captured to assess ectoparasite infestations. Ectoparasite prevalence and ectoparasite species richness (EPSR) were statistically related to nine ecological variables applying generalized linear mixed models. Hosts harbored ticks (Haemaphysalis microcebi), mites (Schoutedenichia microcebi, Listrophoroides spp., Laelaptidae gen. spp.) and sucking lice (Lemurpediculus spp., Polyplax sp., Hoplopleuridae gen. sp.). Parasite prevalence differed significantly between host species for all detected parasite taxa. Proximity to the forest edge led to a significant reduction in ectoparasites. Parasite-specific edge effects were observed up to a distance of 750 m from the forest edge. The obtained results imply that habitat fragmentation impacts ectoparasite communities, in particular by negatively affecting temporary parasite species. The results are best explained by an interplay of parasite life cycles, ...

CONCLUSION: The patterns of care and treatment outcomes were potentially consistent with world standards, needing future validation. This is the largest study of newly diagnosed nasopharyngeal cancer in Indonesia, a huge disease burden, providing an important basis for the clinical management of this disease.

Conclusion. Most hematological and biochemical profiles were significantly lower in the Schistosoma mansoni-positive group as compared with the control group. Most hematological and biochemical profiles decline significantly as the parasite density increased. Hence, with Schistosoma treatment, supportive treatment against hematological and biochemical disorders is recommended. PMID: 32454838 [PubMed]

r A Abstract Human encroachment of natural habitats bears the threat of disease transmission between native and introduced species that had not come into contact before, thus promoting the spread of new diseases in both directions. This is a matter of concern especially in areas where human-wildlife contact has not been intense in the recent past. In southwest Madagascar, we collected ectoparasites from various mammalian hosts and chicken, and examined their host preferences and their prevalence in relation to season and habitat degradation. Field-work took place in the northern portion of Tsimanampetsotsa Nationa...

AbstractHistorically, rodents-ectoparasites are responsible for many diseases in human and domestic animal communities because they are well-adapted to the environment and nutritional resources. In addition, ectoparasites can affect the reproductive rates, ecological fitness and the dispersal pattern of their hosts. Data was compiled through all publications relating to ectoparasites fauna from Iranian rodents. Host specificity, rodent-parasites interaction, geographical distribution, ecological trends as well as the medical or veterinary importance of ectoparasites are considered in this review. Also, results compared wit...

The salmon louse, Lepeophtheirus salmonis, is an endemic ectoparasite on salmonid fish that is challenging for the salmon farming industry and wild fish. Salmon lice produce high numbers of offspring, necessitating sequestration of large amounts of lipids into growing oocytes as a major energy source for larvae, most probably mediated by lipoproteins. The microsomal triglyceride transfer protein (MTP) is essential for the assembly of lipoproteins. Salmon lice have three L. salmonis MTP (LsMTP) transcript variants encoding two different protein isoforms, which are predicted to contain three β-sheets (N, C, and A) and a...

To better understand the lice species parasitizing swan geese that are endemic to East Asia, we collected chewing lice from 14 wild geese caught at 3 lakes in northeastern Mongolia. T...

Marie McIntyre Atlantic salmon’s (Salmo salar) annual aquaculture production exceeds 2M tonnes globally, and for the UK forms the largest single food export. However, aquaculture production is negatively affected by a range of different diseases and parasites. Effort to control pathogens should be focused on those which are most “important” to aquaculture. It is difficult to specify what makes a pathogen important; this is particularly true in the aquatic sector wh...

Abstract The Yunnan red‐backed vole Eothenomys miletus (Rodentia: Cricetidae) is an endemic rodent species and reservoir host of zoonoses in southwest China. Based on a large host sample (2463 voles collected from 39 localities between 2001 and 2013), a general analysis of four categories of ectoparasite (fleas, sucking lice, chigger mites and gamasid mites) on E. miletus across its entire range of distribution was made. This analysis identified a total of 71 895 ectoparasites belonging to 320 species (30 species of flea, 9 of sucking louse, 106 of gamasid mite and 175 of chigger mite) with a high prevalenc...

In this study, haematological reference intervals were developed for free-ranging endangered Australian sea lion (Neophoca cinerea) pups within the context of endemic hookworm (Uncinaria sanguinis) infection and the effects of pathogen, host, and environment factors on the variability of haematological parameters were investigated. Uncinaria sanguinis was identified as an important agent of disease, with infection causing regenerative anaemia, hypoproteinaemia, and a predominantly lymphocytic–eosinophilic systemic inflammatory response. Conversely, the effects of sucking lice (Antarctophthirus microchir) were less ap...
