Another reason for repeating my original experiments is, because it has become evident that there is a very large margin of unavoidable error in this method of investigation, and only by a long series of observations by different men can conclusions in any way reliable be obtained. One factor of error for which no correction is possibie, is the great variation in resistance found in individual ...

BACKGROUND The aim of the present study was to determine the prevalence of ectoparasite infestations in stray dogs in Mazandaran, Gilan and Qazvin Provinces in fall and winter in 2013(December to March). METHODS Seventy dogs in 2013, from these Provinces were examined for ectoparasite infestation and diagnosis of them based on parasitological methods and identification keys was done. RESULT...

Fleas are haematophagous ectoparasites that exhibit varying degrees of host specificity. Flea abundance is highest on principal hosts and lower on auxiliary hosts but may vary greatly among auxiliary hosts. We investigated the feeding and energy expenditure for digestion in two flea species Parapulex chephrenis and Xenopsylla ramesis on a principal host (Acomys cahirinus and Meriones crassus, r...

BACKGROUND Ectoparasites of mammalian hosts play an important role for transmission of diseases from the host reservoirs to human. The aim of this study was to determine the species composition and infestation parameters for parasitic arthropods associated with Rhombomys opimus. METHODS Ectoparasites of R. opimus were collected from seven endemic district of ZCL in Iran including Shirvan and ...

Bartonella spp. are erythrocytic bacteria transmitted via arthropod vectors, which infect a broad range of vertebrate hosts, including humans. We investigated transmission dynamics and host-parasite-vector relationships for potentially zoonotic Bartonella spp. in invasive Rattus rattus hosts and associated arthropod ectoparasites in Madagascar. We identified five distinct species of Bartonella ...
