Theory predicts a positive relationship between parasite infection intensity and host density. However, this generalization is complicated in natural systems by differences in life history among parasite taxa, e.g., transmissibility. Accordingly, predictions relating host density to parasite load should be specific to each parasite taxon. To illustrate this, we studied parasites that differed g...

rodent ectoparasites seems have a main role in transmission of some zoonotic pathogens from commensal rats to human and pets such as leishmaniasis, plague, cchf, etc. so rodents as the main reservoirs, are potential health dangers in human communities. the aim of this study was to determine the prevalence and frequency of identified ectoparasites in north of tehran . rodents were captured with ...
