We detected 3 Bartonella species in wild rabbit fleas from Colorado, USA: B. vinsonii subsp. berkhoffii (n = 16), B. alsatica (n = 5), and B. rochalimae (n = 1). Our results support the establishment of the zoonotic agent B. alsatica in North America.

Wildlife are hosts of ectoparasites, such as fleas and ticks that may transmit human and animal pathogens. Little is known about the ecology of many ectoparasite species native to southern Texas, or their role in pathogen maintenance and transmission. Much attention has been given to the role of nonnative nilgai antelope as cattle fever tick hosts and agents of dispersal, but little attention has been given to other ectoparasites that may utilize nilgai antelope as hosts.

Wild rabbits in Australia developed genetic resistance to the myxoma virus, which was introduced as a biological control agent. However, little is known about the rate at which this evolutionary change occurred. We collated data from challenge trials that estimated rabbit resistance to myxomatosis in Australia and expressed resistance on a continuous scale, enabling trends in its development to be assessed over 45 years up to 1995.

Lagomorphs-principally rabbits and hares-have been implicated as hosts for vectors and reservoirs for pathogens associated with multiple rickettsial diseases. Western North America is home to diverse rickettsial pathogens which circulate among multiple wild and domestic hosts and tick and flea vectors. The purpose of this study was to assess lagomorphs and their ectoparasites in 2 locations in northern Baja California, Mexico, for exposure to and infection with rickettsial organisms.

Fleas are an important member of the North African entomofauna. An understanding of the risks of flea-borne diseases to public and veterinary health can be gained with surveys of their abundance, distribution, and hosts. The aims of this study were to make an initial assessment of flea (Siphonaptera) species collected from a selected number of mammalian hosts in Algeria and debate their medical and veterinary importance.

Background: Fleas (Insecta: Siphonaptera) are considered as highly specialized bloodsucking on mammals such as humans, livestock, dog, cat, rabbit, squirrels, rats, and mice. The desire for blood feeding from warm-blooded animals has led to becoming an intermediate host for some tapeworms like . The aim of this study was to detect larval infection in fleas of dogs living in Mesh-kinshahr County, northwest of Iran.
