Abstract: Ectoparasites of various species of rodents were examined from Sarepole Zehab, Kermanshah Province Iran during 2005. This city is bordered with Iraq. A total of 139 rodents included 6 species of hosts were captured during all different seasons and examined for ectoparasites using live trap. The area of study was mainly plateu (70%) and mountanous. The hosts including: Microtus socialis, Mus musculus, Rattus rattus, Nesokia indica, Meriones persicus and Tatera indica. The 9 species of ectoparasites recovered included 3 fleas (Pulex irritans, Xenopsylla buxtoni, Nosopsyllus medus), one sucking lice (Polyplax spinolosa), two ticks (Rhipicephalus sp., Hyalomma sp.), and 3 mites (Lealaps nuttalli, Dermanysus sanguineus, Ornithonussus bacoti). Among all arthropod collected, the lice and flea had the most and least frequency, i.e. 77.7% and 4.4%, respectivelly. The data showed that the ectoparasites on some rodent hosts tend to prefer particular host body sites, and that some ectoparasite species sites may overlap owing to their inaccessibility to the host.

Abstract: in venezuela, the increment and expansion of autochthonous fishes farming, have prompted the importance of identifying the parasitic diseases that can affect these species under cultivation conditions. with that purpose, a study was carried out to determine the ectoparasitic fauna infecting the cachama (colossoma macropomum) and the hybrid cachama x morocoto (c. macropomum x piaractus brachypomus) under culture. the samplings were carried out in the ponds of delta amacuro experimental station of the national institute of agricultural research (inia), and in private fish farms of the region. fresh smear of gills and skin coming from 139 cachamas and 128 hybrids were prepared and observed under microscope. six species of parasites were identified: the monogenea, anacanthorus spatulatus; the mixosporeans, myxobolus sp. and henneguya sp.; the ciliated protozoan, trichodina sp. and epistylis sp. and the copepoda, ergasilus sp., a. spatulatus, myxobolus sp. and trichodina sp. were common to both species of fish, being present, in most of the cases, in mixed parasitism. from these parasites, the monogenea anacanthorus spatulatus occurred with the highest prevalence, while, the cachama was the host showing the highest infection prevalence. the identified parasites apparently neither cause economic impact to the production nor represent any danger for human consumption.

Graciolli, Gustavo;Bianconi, Gledson V.;
Revista Brasileira de Zoologia , 2007, DOI: 10.1590/S0101-81752007000100033
Abstract: the information available on streblid and nycteribiid bat flies and their hosts are scant in the araucaria forest (af) and there are no data on richness, distribution patterns or abundance of these ectoparasites in bat communities. therefore, we conducted a study on bats and their ectoparasites in af remnants (approximately 470 ha) located in the municipality of fazenda rio grande, paraná state, between december 2001 and may 2003. twelve individuals of three species of nycteribiidae and 119 individuals of six species of streblidae were collected on 127 bats (four species of phyllostomidae and seven of vespertilionidae). five of the six species of streblid were found exclusively on sturnira lilium (e. geoffroy, 1810) and artibeus lituratus (olfers, 1818). we collected megistopoda proxima (séguy, 1926) on 62 s. lilium examined with prevalence of 65.4% and mean intensity of 2.00; aspidoptera falcata wenzel, 1976, respectively, with 13.5% and 2.29; trichobius phyllostomae kessel, 1925 with 7.7% and 1.00; and metelasmus wenzeli graciolli & dick, 2004 with 1.6% and 4.00. we did not find significant differences in prevalence (p = 0.544) and mean intensity (p = 0.361) between the sexes of s. lilium. on 26 a. lituratus captured we found only paratrichobius longicrus (miranda-ribeiro, 1907) with prevalence of 32% and mean intensity of 1.50.

Calderón-Arguedas,Olger; Troyo,Adriana; Castro-Ugalde,Jorge;
Revista Costarricense de Ciencias Médicas , 2004,
Abstract: a case of dermatitis associated to macronyssid mites in a female patient from tuetal norte, an rural town in the province of alajuela, costa rica is described. the patient showed an intense and generalized rash with constant pruritus, and the other family members presented similar manifestations. the patient described "small animals" walking over her body and on the house walls. a sample of these organisms was cleared and mounted for microscopic examination. the analysis of the preparations revealed mites belonging to the family macronyssidae. treatment was performed with tetmosol? soap, eurax? lotion and atarax?. the application of an acaricid solution in the house was recommended. the patient was cured 10 days after the beginning of treatment
Distribution of ectoparasites of Canis lupus familiaris L. (Carnivora: Canidae) from Panama
Bermúdez C,Sergio; Miranda C,Roberto;
Revista MVZ Córdoba , 2011,
Abstract: objetive. to determine the distribution of ectoparasites in dogs in panama. materials and methods. there were surveyed 720 canines belonging to 57 communities. results. the results showed that 84% of the dogs were infested with at least one species of ectoparasite. dogs from lowlands showed a higher percentage of parasitism and a greater biodiversity of parasites than dogs from highlands. there were found seven species of ticks, four species of fleas, two species of lice, and one specie of botfly. the ticks rhipicephalus sanguineus, amblyomma cajennense, a. ovale and the flea ctenocephalides felis were widespread; however ixodes boliviensis and pulex simulans showed a much narrower geographic distribution and they were found only in dogs from highlands. the flea species rhopalopsyllus cacicus and the tick haemaphysalis juxtakochi were found for the first time in panamanian dogs. conclusions. the environmental situation in panama, can encourage that wildlife ectoparasites parasitized dogs in absence of their native hosts. this condition may increase transmission risk of some diseases where the ticks and fleas are vectors.

Koedoe : African Protected Area Conservation and Science , 2006, DOI: 10.4102/koedoe.v49i1.106
Abstract: This report provides additional information on the morphology of Damalinia (Tricholipeurus) antidorcus, previously described only by light microscopy. Live lice were collected and prepared for viewing by SEM. Micromorphological features investigated included aspects of the forehead, mandibles and spiracles. The average length of the males was 2.0 mm and females 2.04 mm. The anterior hyalin region of the head was notably emarginated. Awell-developed medial groove on the ventral surface of the head between the mandibles was noted. The surface of the epipharynx was smooth. The labrum with its typical scale-like appearance gradually changed into the pulvinal area of the clypeus. Both genders had notched left mandibles. The mandibles were highly serrated on the oral surfaces. Situated ventrally below and caudal to the mandibles were a pair of labial palpi. The immediate area between, and surrounding the labial palpi was littered with numerous spiked setae and two well developed larger setae raised at their bases. The tips of the palpi bore three larger and longer sensory setae. Palpi of this nature are described here for the first time in D. antidorcus.
