. Vector Borne Zoonotic Dis., 11(5), 453–70.
Abstract: Abstract The ubiquity of ticks and their importance in the transmission of pathogens involved in human and livestock diseases are reflected by the growing number of studies focusing on tick ecology and the epidemiology of tick-borne pathogens. Likewise, the involvement of wild birds in dispersing pathogens and their role as reservoir hosts are now well established. However, studies on tick-bird systems have mainly focused on land birds, and the role of seabirds in the ecology and epidemiology of tick-borne pathogens is rarely considered. Seabirds typically have large population sizes, wide geographic distributions, and high mobility, which make them significant potential players in the maintenance and dispersal of disease agents at large spatial scales. They are parasitized by at least 29 tick species found across all biogeographical regions of the world. We know that these seabird-tick systems can harbor a large diversity of pathogens, although detailed studies of this diversity remain scarce. In this article, we review current knowledge on the diversity and global distribution of ticks and tick-borne pathogens associated with seabirds. We discuss the relationship between seabirds, ticks, and their pathogens and examine the interesting characteristics of these relationships from ecological and epidemiological points of view. We also highlight some future research directions required to better understand the evolution of these systems and to assess the potential role of seabirds in the epidemiology of tick-borne pathogens.

. (2011). Seroepidemiology of nine zoonoses in Viljujsk, Republic of Sakha (Northeastern Siberia, Russian Federation).
. Vector Borne Zoonotic Dis., 11(2), 157–60.
Abstract: A seroepidemiology survey of nine zoonoses was carried out in 2007 on 90 healthy adult volunteers in Viljujsk, a northern city in the Republic of Sakha (Eastern Siberia). The seroprevalence of Lyme borreliosis was 3.3% by immunofluorescence. None of the subjects displayed a positive enzyme-linked immunosorbent assay/Western blot result for alveolar or cystic echinococcosis. The seroprevalence of toxocariasis by Western blot was 4.4%, and 8.9% of the subjects had anti-Toxoplasma IgG. By enzyme-linked immunosorbent assay, the seroprevalence of trichinellosis was 4.4%. Three subjects were simultaneously positive for tick-borne encephalitis and West Nile infection, so no clear diagnostic conclusion could be reached for these flavivirus diseases. Interestingly, Crimea-Congo hemorrhagic fever had an 11.1% seroprevalence rate, indicating that Viljujsk is the most northern focus of this infection. Additionally, this finding suggests a potential involvement of Crimea-Congo hemorrhagic fever agent, or of another member of the Bunyaviridae family, in the genesis of the so-called Viljujsk encephalomyelitis.

. (2011). Seabirds and the circulation of Lyme borreliosis bacteria in the North Pacific
. Vector Borne Zoonotic Dis., 11(12), 1521–1527.
Abstract: Seabirds act as natural reservoirs to Lyme borreliosis spirochetes and may play a significant role in the global circulation of these pathogens. While Borrelia burgdorferi sensu lato (Bbsl) has been shown to occur in ticks collected from certain locations in the North Pacific, little is known about interspecific differences in exposure within the seabird communities of this region. We examined the prevalence of anti-Bbsl antibodies in 805 individuals of nine seabird species breeding across the North Pacific. Seroprevalence varied strongly among species and locations. Murres (Uria spp.) showed the highest antibody prevalence and may play a major role in facilitating Bbsl circulation at a worldwide scale. Other species showed little or no signs of exposure, despite being present in multispecific colonies with seropositive birds. Complex dynamics may be operating in this wide scale, natural host-parasite system, possibly mediated by the host immune system and host specialization of the tick vector.
