Abstract
Parasitic relationships between Neotropical bats and their ectoparasites are not well known, even though parasitism is one of the factors that can affect the fitness of a host population. This study characterized parasite-host relationships in relation to sex, age, body size and reproductive status in a population of Anoura geoffroyi using the indices of Prevalence, Mean Intensity and Mean Abundance. Total prevalence for 93 sampled bats was 94.6%. Two species of streblid flies that are considered primary parasites of A. geoffroyi, Exastinion clovisi (n = 203) and Anastrebla modestini (n = 152), were the most abundant ectoparasites, followed by Trichobius sp. (n = 7). Two mite species, Periglischrus vargasi (Spinturnicidae) (n = 98) and Spelaeorhynchus praecursor (Spelaeorhynchidae) (n = 11), were also found. We recorded higher mean abundance and intensity of parasitism in pregnant females compared to reproductive males and reproductively inactive females, for different specific associations of ectoparasites. Host age and body condition had no effect on the parasitological indices. Even with high rates of parasitism, parasitic load did not influence host body condition, but infestation rates by mites were higher in reproductive males and higher by flies in reproductive females, showing that ectoparasites can have variable influences between the different stages of the life history of these host bats. Thus, the reproductive activity of the hosts could be an adverse factor for resistance to parasite infestations.

Abstract
Reproductive costs may increase the susceptibility of breeding females to parasites. Compatibility may be modulated by immunity and nonimmunological factors. However, experimental tests attempting to unravel the role of nonimmunological compatibility to parasites are scarce. We experimentally infected breeding and nonbreeding females with pseudoectoparasites (PEPs) to analyse how nursing a kid affects neatness in the Iberian ibex ( Capra pyrenaica Schinz, 1838). Our results revealed that nursing a kid does not seem detrimental to neatness in female Iberian ibex in terms of nonimmunological compatibility to contact-transmitted foreign bodies. Consequently, it seems that increased susceptibility of breeding females to contact-transmitted parasites may be mainly mediated by increased exposure or increased immunological compatibility to parasites.
