“…Migratory birds can carry ticks and pathogens over great distances while upland game birds can host these ticks and may have exposure to pathogens [ 12 , 13 , 22 , 39 ]. On a global scale, our results support additional studies documenting findings of Borrelia species in avifauna, and importantly the associated vectors in various locations [ 40 , 41 , 42 ], highlighting the importance of birds in the transmission, maintenance and geographic spread of tick-borne pathogens. In this study, we reported B .…”

The Borrelia genus contains two major clades, the Lyme borreliosis group, which includes the causative agents of Lyme disease/borreliosis (B. burgdorferi sensu stricto and other related B. burgdorferi sensu lato genospecies), and the relapsing fever borreliosis group (B. hermsii, B. turicatae, and B. parkeri). Other unclassified reptile- and echidna-associated Borrelia spp. (i.e., B. turcica and ‘Candidatus Borrelia tachyglossi’, respectively) do not belong in either of these two groups. In North America, Borrelia spp. from both of the major clades are important pathogens of veterinary and public health concern. Lyme disease is of particular interest because the incidence in the northeastern United States continues to increase in both dogs and humans. Birds have a potentially important role in the ecology of Borrelia species because they are hosts for numerous tick vectors and competent hosts for various Borrelia spp. Our goal was to investigate the prevalence of Borrelia spp. in four free-living species of upland game birds in Pennsylvania, USA including wild turkey (Meleagris gallopavo), ruffed grouse (Bonasa umbellus), ring-necked pheasants (Phasianus colchicus), and American woodcock (Scolopax minor). We tested 205 tissue samples (bone marrow and/or spleen samples) from 169 individuals for Borrelia using a flagellin gene (flab) nested PCR, which amplifies all Borrelia species. We detected Borrelia DNA in 12% (24/205) of samples, the highest prevalence was in wild turkeys (16%; 5/31), followed by ruffed grouse (13%; 16/126) and American woodcock (3%; 1/35). All pheasants (n = 13) were negative. We sequenced amplicons from all positive game birds and all were B. burgdorferi sensu stricto. Our results support previous work indicating that certain species of upland game birds are commonly infected with Borrelia species, but unlike previous studies, we did not find any relapsing fever borreliae.

“…Ixodes auritulus is a cosmopolitan tick species distributed through the Afrotropical, Australasian, Nearctic, and Neotropical Zoogeographic Regions and all stages parasitize mainly birds ( Nava et al., 2017 ; Guglielmone et al., 2020 ). The presence of Bo r relia burgdorferi ( sensu lato ) was recently reported in I. auritulus from Argentina and Uruguay ( Cicuttin et al., 2019 ; Carvalho et al., 2020 ); however, information about the presence of other pathogens is scarce.…”

“…group were carried out in this part of the continent, but the vector species were ticks of the genus Ixodes with no reports of infestation in humans (Carvalho et al, 2020). The four fla haplotypes were registered in GenBank accession numbers MK160129, MK160130, MK160131, and MK160132 by Carvalho et al, (2020). This is the first serological detection of Borrelia spp.…”

This study aimed to verify the presence of IgG antibodies against Borrelia burgdorferi sensu lato (s.l) in domestic dogs in western Cuba. Serum samples were analyzed by indirect enzyme-linked immunosorbent assay (ELISA), using crude antigens of a B. burgdorferi strain of North American origin. To verify the presence of Borrelia spp., deoxyribonucleic acid (DNA) extracted from individual blood samples was analyzed by nested-PCR, with markers targeted for amplification of portions of the flagellin B gene (flaB) present in Borrelia spirochetes. Ticks were also collected through inspection of the animals. Sera from 93 of 176 (52.84%) dogs were reactive to the indirect ELISA. Geographic prevalence varied from 54.35% (25/46) in Boyeros, 44.44% (20/45) in Cotorro, 66.67% (22/33) in Habana del Este, and 50% (26/52) in San José de las Lajas. There was no statistical difference between these tested variables. No blood samples analyzed were positive for the Borrelia flaB gene.
