INTRODUCTION Eosinophilia and anemia are very common hematological alterations in the tropics but population-based studies scrutinizing their value for diagnosing parasitic infections are rare. METHODOLOGY A cross-sectional study was conducted in a rural district in northeast Brazil where parasitic infections are common. Stool and blood samples were collected and individuals were clinically e...

—Only a single previous study has examined ectoparasites of the occult bat (Myotis occultus), from which only 2 species of fleas were identified. For our study, we examined 202 individuals, 52 fresh hosts and 150 museum specimens, from New Mexico and southern Colorado for ectoparasites. We recorded 2158 ectoparasites, 634 from fresh hosts and 1524 from museum specimens. Ectoparasites belonged t...

A survey of ectoparasites on rodents was carried out bimonthly from April 2008 to March 2009 in 3 districts of Sukhothai Province, northern Thailand. A total of 130 rodents comprising 8 species of hosts were captured and examined for ectoparasites. The hosts examined were Bandicota indica, Bandicota savilei, Rattus losea, Rattus rattus, Rattus exulans, Rattus norvegicus, Menetes berdmorei and T...

The mark-recapture method allows analysis on the variation in the abundance of bat ectoparasites at consecutive captures. The objectives of this study were to compare the pattern of Streblidae parasitism between capture and recapture of C. perspicillata; ascertain whether the abundance of Streblidae varied with time after removal of ectoparasites at capture and analyze whether the intensity of ...

background: rodents play an important role as reservoir of some pathogens, and the host of some ectoparasites as well. these ectoparasites can transmit rodents’ pathogens to human or animals. the aim of this study was to assess the distribution and infestation load of ectoparasites on rodents in meshkin-shahr district, northwestern iran . method: rodents were captured using baited live traps in...

background:   the objective was to determine the prevalence of ectoparasite infestations in referred companion dogs to veterinary hospital of shahid chamran university of ahvaz, from 2009 to 2010 . methods: a total of 126 dogs were sampled for ectoparasites and examined by parasitological methods. the studied animals were grouped based on the age (<1 year, 1–3 years and >3 years), sex, breed an...

A total of 100 ground squirrels, Citellus (C.) citellus were trapped in rural regions of Konya in order to determine the presence of ectoparasites. Of these C. citellus examined, 16% (16/100) were infected with at least one ectoparasite species. Two types of ectoparasites were found including 10% fleas and 7% ticks. Only two flea species were found on C. citellus including Nosopsyllus fasciatus...

Birds are plagued by an impressive diversity of ectoparasites, ranging from feather-feeding lice, to featherdegrading bacteria. Many of these ectoparasites have severe negative effects on host fitness. It is therefore not surprising that selection on birds has favored a variety of possible adaptations for dealing with ectoparasites. The functional significance of some of these defenses has been...

Host-choice experiments were carried out with rodent and bat ectoparasites on Ilha Grande, state of Rio de Janeiro, Brazil. We constructed experimental chambers that enclosed three different rodent or bat host species, and then introduced a selected set of ectoparasitic arthropods. When given the opportunity to choose among host species, the ectoparasites showed a strong tendency to select thei...

Cryptic coloration is a classic example of evolution by natural selection. However, it has been studied almost exclusively in predator-prey systems, despite the fact that it may evolve in other groups, such as ectoparasites. The principle defense of hosts against ectoparasites is grooming behavior, which has a visual component. Host-imposed selection should lead to the evolution of background m...
