Detection of tick-borne pathogens in ticks collected in the suburban area of Monte Romano, Lazio Region, Central Italy.

CONCLUSION: Overall, 182 ticks (71%) were infected with at least one pathogen; among these co-infections were found in 94 ticks. Tick borne pathogens identified were C. burnetii, B. burgdorferi s.l., Bartonella spp., Rickettsia spp., Francisella spp., and Ehrlichia spp. In R. bursa and H. marginatum, the presence of B. burgdorferi s.l. was positively correlated with that of C. burnetii, Rickettsia spp., and Bartonella spp. and their coinfection probabilities were 29.8%, 22.7% and 11.7%, respectively; the probability of coinfection for Francisella spp. and Rickettsia spp. and for Francisella spp. and Bartonella spp. was 14.9% and 17.9%, respectively. In R. (Boophilus) annulatus, the probability of coinfection between C. burnetii and B. burgdorferi s.l. was 11.3%, while those between C. burnetii and Bartonella spp. and between B. burgdorferi s.l. and Bartonella spp. were 0.8%. Further studies are needed in order to assess the risk associated with these unusual tick-borne pathogens in Central Italy. PMID: 31264637 [PubMed - in process]

The American Lyme Disease Foundation is dedicated to the prevention, diagnosis, and treatment of Lyme disease which, in the United States, has been defined historically as a tick-borne bacterial infection caused by the spirochete, Borrelia burgdorferi sensu stricto. Through its website, the Foundation plays a major role in providing reliable and scientifically accurate information to the public, medical community and various public health agencies about Lyme disease and its impact on human health.

This study demonstrates the effect of only simultaneous infection by B. burgdorferi and B. microti on each pathogen, immune response and on disease manifestations with respect to infection by the spirochete and the parasite. In our future studies, we will examine the overall effects of sequential infection by these pathogens on host immune responses and disease outcomes.

Authors: Conforti C, Vezzoni R, Retrosi C, Longone M, Corneli P, Magaton-Rizzi G, Nan K, Di Meo N, Zalaudek I Abstract Lyme disease is a tick-borne illness, which is tipically caused by Borrelia Burgdoferi. Over time, a typical Borreliosis skin reaction takes shape, i.e. the formation of an annular erythema that tends to expand centrifugally with erythematous edges whose diameter can reach up to 20 cm. The symptoms of Lyme disease are not only cutaneous but there may be a systemic involvement. Obviously, this disease can also affect pregnant women and for this reason this review aims to summarize the main ways of t...

Borrelia burgdorferi is a tick-borne bacterium responsible for approximately 300,000 annual cases of Lyme disease (LD) in the United States, with increasing incidences in other parts of the world. The debilitating nature of LD is mainly attributed to the ability of B. burgdorferi to persist in patients for many years despite strong anti-Borrelia antibody responses. Antimicrobial treatment of persistent infection is challenging. Similar to infection of humans, B. burgdorferi establishes long-term infection in various experimental animal models except for New Zealand White (NZW) rabbits, which clear the spirochete within 4 t...

This study assessed the prevalence of B. burgdorferi s. l. among four non-Peromyscus rodents in a prairie ecosystem in the Midwestern United States over a four-year period. We found high prevalences of the bacteria in all four species studied. Our results help to support the roles of Microtus species as reservoirs of B. burgdorferi and add to the literature that suggests Zapus hudsonius may also be a reservoir. Additionally, we identified a previously unknown possible reservoir, Ictidomys tridecemlineatus. Our study also identifies the need to study the dynamics of Lyme borreliosis in habitats and areas outside of the typi...

Publication date: Available online 11 June 2019Source: Ticks and Tick-borne DiseasesAuthor(s): Kalvis Brangulis, Inara Akopjana, Ivars Petrovskis, Andris Kazaks, Kaspars TarsAbstractThe spirochete Borrelia burgdorferi sensu lato is the causative agent of Lyme borreliosis – the most common tick-borne disease in Europe and the United States. Spirochetes are transmitted from infected Ixodes ticks to the mammalian host when the ticks feed. In general, the transfer process of the borreliae is quite complicated, as the environments in the tick and the new mammalian host differs significantly. Therefore, Borrelia changes th...
