“…34 The PCR were carried out in a total of 50 μL solution containing 1X PCR buffer minus Mg, 1.5 mM MgCl2, 0.2 mM dNTPs, 1 U of Platinum TaqDNA Polymerase, and 0.2 μM of each primer. For all PCR reactions, one positive control (DNA extracted from Borrelia anserina culture) and two negative controls (water) were included.…”

Blood samples collected from 201 humans, 92 dogs, and 27 horses in the state of Espirito Santo, Brazil, were tested by polymerase chain reaction, indirect immunofluorescence assays, and indirect enzyme-linked immunosorbent assay for tick-borne diseases (rickettsiosis, ehrlichiosis, anaplasmosis, borreliosis, babesiosis). Our results indicated that the surveyed counties are endemic for spotted fever group rickettsiosis because sera from 70 (34.8%) humans, 7 (7.6%) dogs, and 7 (25.9%) horses were reactive to at least one of the six Rickettsia species tested. Although there was evidence of ehrlichiosis (Ehrlichia canis) and babesiosis (Babesia canis vogeli, Theileria equi) in domestic animals, no human was positive for babesiosis and only four individuals were serologically positive for E. canis. Borrelia burgdorferi-serologic reactive sera were rare among humans and horses, but encompassed 51% of the canine samples, suggesting that dogs and their ticks can be part of the epidemiological cycle of the causative agent of the Brazilian zoonosis, named Baggio-Yoshinari Syndrome.

“…In Europe and Asia especially, the development of a uniform approach for the serological evaluation of LB is complicated by the prevalence of organisms from the three or more genospecies of B. burgdorferi sensu lato and by significant antigenic variation between and within each genospecies (Wang et al, 1999). Moreover, in the USA 'Borrelia lonestari' exposure may confound serological results (Stromdahl et al, 2003).…”

Recombinantly produced borrelial BBK32 protein fragments originating from Borrelia burgdorferi sensu stricto, Borrelia garinii and Borrelia afzelii were evaluated as antigens in the serology of Lyme borreliosis (LB). In ELISA, a mid-portion hydrophilic fragment reacted with LB patient sera. Of the 23 patients with culture-or PCR-positive erythema migrans (EM), 43 % at diagnosis and 52 % at convalescence were positive for at least one Borrelia species-specific variant BBK32 fragment antigen. In parallel ELISAs with BBK32 whole proteins from the three borrelial subspecies as antigens, 17 % at diagnosis and 26 % at convalescence were positive. These results suggest that BBK32 protein fragments may improve the early IgG serology of LB compared to the BBK32 whole protein.

“…20,23,25 Borrelia lonestari has additionally been identified in A. americanum ticks that were removed from humans, including patients from Kentucky. 26 Ehrlichia chaffeensis is a gram-negative obligate intracellular bacterium and the etiologic agent of human monocytotrophic ehrlichiosis. [27][28][29] Ehrlichia chaffeensis is maintained in a zoonotic cycle involving its principal reservoir, the white-tailed deer ( Odocoileus virginianus ) and A. americanum ticks.…”

Abstract. Rocky Mountain spotted fever, Lyme disease, and ehrlichiosis are tick-borne diseases that are reported annually in Kentucky. We conducted a survey to describe infection prevalence of tick-borne pathogens in Amblyomma americanum and Dermacentor variabilis ticks collected in Kentucky. During 2007-2008, we collected 287 ticks (179 D. variabilis and 108 A. americanum ) from canine, feral hog, horse, raccoon, white-tailed deer, and human hosts in six counties in Kentucky. Ticks were screened for Rickettsia spp., Borrelia spp., and Ehrlichia spp. by using polymerase chain reaction. Forty-one (14.3%) ticks (31 A. americanum and 10 D. variabilis ) were polymerase chain reaction-positive for a Rickettsia spp. Fourteen (4.9%) ticks (6 A. americanum and 8 D. variabilis ) were positive for E. chaffeensis , and 4 A. americanum (1.4%) were positive for E. ewingii . One (0.4%) A. americanum was positive for Borrelia lonestari .
